Embodiment

As shown in Figure 1, the quick fixing nail covering device of one embodiment of the invention comprises:

Outer sleeve 1 is a cylindrical shell and interiorly be perforation 11, and the end is provided with the axial groove 12 that extends to the stage casing so that its tool is flexible, and is provided with fin 13 in its outside, and wherein fin 13 is barb-like gilled rings;

Inner sleeve 2, be a cylindrical shell and interior for the perforation 21, and have first end 22 and a second opposed end 23, wherein first end 22 is provided with button wall 221, and be provided with retaining wall 231 in second end 23, and button wall 221 and the internal diameter of the external diameter that keeps off wall 231 greater than outer sleeve 1 perforation 11, be provided with the axial groove 24 that extends to the stage casing so that its button wall 221 tools are flexible in first end 22 in addition, and in the button wall 221 be provided with tilted guide surface 222, with in the perforation 11 of supporting outer sleeve 1, and be snapped in outer sleeve 1 by tilted guide surface 222 by button wall 221 and retaining wall 231.

As Fig. 2, Fig. 3 and shown in Figure 4, be respectively that the present invention is applied to the roller slide rail, for example for generally small-sized, the exploded view of the drawer sliding rail 3 of low loading and combination schematic representation, and wherein the fixed block 4 of Ying Yonging is a screw, during enforcement, the body of furniture for example, can get out post hole 51 prior to pre-determined constant place 5, and general Furniture fittings supplier, then as shown in Figure 3, inner sleeve 2 can be placed perforation 31 places of roller slide rail 3 earlier, and penetrate the perforation 31 of roller slide rail 3 and be screwed together in inner sleeve 2 by fixed block 4, when roller slide rail 3 and furniture construction, then only need support inner sleeve 2 in the perforation 11 of outer sleeve 1 with tilted guide surface 222 outer sleeve 1 implant post hole 51 again, this inner sleeve 2 can stretching among outer sleeve 1, and utilize the external end edge that wall 221 is butted on outer sleeve 1 of buckleing of inner sleeve 2 first ends 22, as shown in Figure 4, roller slide rail 3 can be fixed in pre-determined constant place 5.
