Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in figure 1, the utility model comprises a clamp body 1, a hinge plate 3, a top block 4, a drill bushing 6 and a hinge bolt 9; the fixture body 1 is provided with a drill bushing hole, and the drill bushing 6 is arranged in the drill bushing hole. One end of the hinge plate 3 is hinged with the clamp body 1, the hinge plate 3 is perpendicular to the axis of the drill sleeve hole, the other end of the hinge plate 3 is hinged with a hinge bolt 9, and the upper end of the hinge bolt 9 penetrates through a bolt groove in the clamp body 1 and is fixed through a nut 7. The ejector block 4 is arranged on the hinge plate 3 and located right below the drill bush 6, and a positioning pin 5 is arranged in a central hole of the drill bush 6.
The hinge plate 3 is provided with a waist-shaped hole 31 and a pin hole 33 at the center, the axis of the waist-shaped hole 31 is vertical to the upper end surface of the hinge plate 3, the axis of the pin hole 33 is vertical to the axis of the waist-shaped hole 31, and the pin hole 33 is a through hole. The lower part of the top block 4 is an installation part matched with the waist-shaped hole, the installation part is inserted in the waist-shaped hole, the installation part is also provided with a pin hole corresponding to the pin hole 33, and the installation part is connected with the hinge plate 3 through a pin.
