Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
As shown in Fig. 1-Fig. 7, a kind of bucket tooth of the present utility model and the assembling structure of toothholder, including bucket tooth 1, toothholder 2 and
Locking head 3；The bottom of described toothholder 2 and the top of bucket tooth 1 are respectively arranged with union joint 4 and link slot 5, described union joint 4 He
Link slot 5 is connected；The lateral surface of described union joint 4 is provided with hole 6, a location, and the lateral surface of described bucket tooth 1 is provided with
The through hole 8 of one link slot 5 connection, fixes after described locking head 3 passes through hole 8 and hole 6, location and with through hole 8 and hole, location 6
Clamping.
Specifically, the periphery of above-mentioned locking head 3 is provided with the protruding block 7 of 2 circular arcs, hole 6, described location He
The hole wall of through hole 8 is respectively arranged with the locating slot 9 of 4 and 2 circular arcs, and described protruding block 7 is positioned at locating slot 9.
It is hexagonal polygonal hole 10 that the end face of above-mentioned locking head is provided with a structure, pulls for interior hexagonal
Hands connects.
The hole wall of above-mentioned through hole 8 is additionally provided with a breach 14 for placing screws cutter, the cylindrical of described locking head
In face, the side of opposed notches is additionally provided with several cutter grooves 15 contacted with screwdriver, makes screwdriver conveniently be pushed up by locking head 3
Out.
The top in above-mentioned hole 6, location is provided with a stepped hole 11, and the outside of described locking head 3 is provided with and also sets up one
The clamping sheet 12 of individual arc, in described clamping sheet 12 is connected to stepped hole 11 and can rotate along it, and upper and lower two ends contact respectively
