Detailed Description

The following will further describe the embodiments of the present invention with reference to the drawings and examples.

As shown in fig. 1 and 2, the fish scale sleeve gecko comprises a bolt 1 and a sleeve 2, wherein the sleeve 2 is provided with a through hole 3 penetrating through the sleeve 2 along the axial direction, the bolt 1 is arranged in the through hole 3, one end of the bolt 1 is provided with a conical expansion head 4, the sleeve 2 is provided with an expansion part 5 corresponding to the expansion head 4, the expansion part 5 is provided with a plurality of cracks 6 at equal intervals along the circumferential direction, the expansion part 5 is provided with a contact part, the contact part comprises a mounting groove 71 arranged on the expansion part 5, a plurality of contact blocks 72 arranged in the mounting groove 71 and an elastic sheet 73 connecting the contact blocks 72 and the mounting groove 71, the contact resisting blocks 72 are arranged into a fish-scale shape, the adjacent contact resisting blocks 72 are connected end to end, and the other ends of the contact resisting blocks 72, which are opposite to the ends connected with the elastic pieces 73, are arranged into arc surfaces which are obliquely arranged from one end far away from the expansion head 4 to one end close to the expansion head 4. The expansion part 5 is provided with a contact part which can contact with the inner wall of the drill hole when the expansion part 5 expands, so that the friction force between the expansion part 5 and the inner wall of the drill hole is enhanced, the effect of further reinforcing is achieved, and the fixation is firmer; wherein, shell fragment 73 provides thrust for conflict piece 72, make conflict piece 72 contradict with the inner wall of drilling, conflict piece 72 sets up fish scale shape and adjacent conflict piece 72 end to end, can make to mutually support between the contact piece 72 and form a whole, the combined action, it is more firm to make its and drilling between fixed, and conflict piece 72 is by the arc surface of keeping away from the one end of expansion head 4 to the one end slope of expansion head 4, can be in convenient the contact piece 72 to the removal of drilling when outwards moving its and producing the resistance, prevent that the sleeve from leaving from drilling.

In addition, the installation groove 71 can be provided with a plurality of abutting blocks 72 along the circumferential direction of the expansion part 5, and each installation groove 71 is internally provided with a plurality of abutting blocks 72, and the number of the abutting blocks 72 can be freely set as required.

It should be noted that, the contact block 72 may be made of a rubber material, and may be pushed by the elastic sheet 73 to be pressed on the inner wall of the drill hole, so as to provide a certain reaction force to the inner wall of the drill hole by being compressed, thereby fixing the contact block to the inner wall of the drill hole more firmly.

The expansion part 5 is provided with outward-turning sheets 8, and the surface of the expansion head 4 is provided with a plurality of lugs 9 which can extrude the outward-turning sheets 8 to turn outwards.
