A stopper 236 having an outer diameter larger than the outer diameter of the male screw portion 231 is fixed to one end of the male screw portion 231, that is, the end portion of the male screw portion 231,

On the other hand, the male screw portion 231 is formed to have an outer diameter smaller than the outer diameter of the drawer 225. In the case of the drawer 225, And the male screw portion 231 should be formed so as to be smaller than the inner diameter of the drawer 225 because each ring should be movable within the inner diameter of the drawer holder 211 . When the first inclined ring 232, the second inclined ring 235 or the C ring 234 is pressed in the direction of the drawer 225 by the incision elastic ring 233 due to the difference in the inner diameters, So that it can be supported by one end of the base 225.

The first inclined ring 232 is formed in a ring shape so that at least one surface thereof is formed with an inclined surface and is inserted into the male screw portion 231 to be slidable along the male screw portion 231. When the incision type elastic ring 233 or the male screw part 231 is rotated so that the incision type elastic ring 233 is moved in the direction of the drawing board 225, Serves as a guiding means for bending the incision portion on the inclined surface and expanding radially outward.

That is, after the first inclined ring 232 is inserted into the male screw portion 231, the incision elastic ring 233 is inserted into the male screw portion 231. When the lead bar 225 is rotated in the normal direction, When the first inclined ring 232 is blocked at one end of the drawer 225 and is no longer able to move, the drawer 233 is moved in the direction of the drawer 225 with the thread of the male screw portion 231, The incision type elastic ring 233 is bent to the outside along the inclined portion of the first inclined ring 232 so that the incision type elastic ring 233 is further moved in the direction of the take- So that the frictional force is increased by this pressing so that the extended support portion 230 and the drawer 225 can be fixed on the inside of the drawing board insertion portion 211 .

The incision type elastic ring 233 is moved away from the one end direction of the draw board 225 and the incision portion of the incision type elastic ring 233 is moved away from the first inclined ring 232 And the frictional force between the withdrawing base 225 and the extended supporting portion 230 is reduced by the withdrawing portion inserting portion 211 ) From the inner side.

The incision elastic ring 233 is formed in a ring shape having one or more incisions and resiliently restoring the incision. A thread is formed on the inner periphery of the incision elastic ring 233 and inserted into the male screw portion 231, As shown in FIG.

The incision elastic ring 233 is formed so as to extend continuously along one end of the elastic ring 233 in the form of a circular flower and extend at the other end, do.

The incision elastic ring 233 is inserted into the drawer insertion portion 211 so that the outer periphery of the incision portion rubs against the inner periphery of the drawer insertion portion 211, The ring 233 can be moved in the direction of the drawing board 225 by the thread of the male screw portion 231 by rotating the ring 233 to a position smaller than the rotation amount of the drawing board 225 from the inside of the drawing board insertion portion 211. The incision elastic ring 233 which is moved in the direction of one end of the tilting table 225 of the drawer 225 pushes the first tilting ring 232 in the direction of the end of the drawer 225, When the ring 232 is blocked by one end of the drawer 225 and is no longer able to move, the incision extends radially outward along the inclined surface of the first inclined ring 232. Since the cutout portion is already in contact with the inner circumferential edge of the outgoing hook insertion portion 211, as the outgoing hook 225 is further rotated in the forward direction, the cut portion of the cut elastic ring 233 and the cutout insertion portion The extension support portion 230 and the drawer 225 can be firmly fixed to the inside of the drawer-insert portion 211. As a result,

The incision elastic ring 233 is moved in the direction of the counterpart 100 and the incision of the incision elastic ring 233 rides on the inclined surface of the first inclined ring 232 The frictional force between the cut portion of the incision elastic ring 233 and the inner circumferential edge of the drawer support insertion portion 211 is reduced and the extended support portion 230 and the drawer 225 are pulled out So that it can be moved inside the portion 211.

The C-ring 234 is inserted into the male screw portion 231 before the first tilting ring 232. When the C-ring 234 is provided, the first tilting ring 232 is formed with inclined portions on both surfaces thereof desirable.

3, the C-ring 234, the first inclined ring 232, and the incisional elastic ring 233 are inserted in the male screw portion 231 in this order, and then the lead board 225 is rotated forwardly, The C ring 234 is clogged at one end of the drawer 225. When the drawer 225 is further rotated here, the C ring 234 is moved in the direction of the drawer 225, The inclinations of the incision elastic ring 233 are slid and expanded on the other inclined surfaces of the first inclined ring 232. The first incline ring 232 is slid toward the inside of the first inclined ring 232 using the inclined surface. Therefore, both the C-ring 234 and the incised elastic portion expand radially outward to come into close contact with the inner peripheral edge of the draw-out cradle insertion portion 211, so that the extension support portion 230 and the draw- As shown in Fig.

Since the C-ring 234 is formed to have only one opening, the resilient force of the C-ring 234 is much stronger than that of the incision elastic ring 233, so that the C-ring 234 can not be extended as desired. Accordingly, in the present invention, a second inclined ring 235 is further provided between the C-ring 234 and one end of the draw-out bar 225 for smooth expansion of the C-ring 234.

The second inclined ring 235 is inserted into the male screw portion 231 and is provided between one end of the drawer 225 and the C ring 234 and is provided with an inclined surface on one side in the direction of the C ring 234, Shaped elastic ring 233 allows the C-ring 234 to extend along the inclined plane when the C-ring 234 is moved in the direction of the draw-out base 225.

The second inclined ring 235 is inserted into the male screw portion 231 in the order of the second inclined ring 235, the C ring 234, the first inclined ring 232, and the incisional elastic ring 233 , So that one side and the other side of the C-ring 234 are extended along the inclined portion so that easy expansion can be achieved.

In addition, at this time, a plurality of grooves can be formed in the longitudinal direction on the outer circumference of the C ring 234, and the frictional force with the inner circumferential edge of the outgoing cage insertion portion 211 can be easily .

The spring 237 serves to enable the incision elastic ring 233 to be quickly moved in the direction of the opponent 100 during the reverse rotation of the drawer 225. For this purpose, the spring 237 is inserted into the male screw portion 231, The other end is supported on one end of the base 225 or on the inclined face of the second inclined ring 235 and one end is supported on the inside of the incisional elastic ring 233. [ The spring 237 may be further provided with a spring retainer 238 at the other end to more easily provide an elastic force to the incision elastic ring 233.
