The holder is connected, the left side of the right holder is connected with the right holder, and the holder and the holder are connected by flanges. Both the left side of the left holder and the right side of the right holder have bosses, and the two sides of the base Screw rods are installed on both sides, and the screw rods reach the boss of the clamp body through the internal thread screw holes on both sides of the base. Lock nuts are installed on the outside of the base on the screw rods, and rotating handles are installed on the outer ends of the screw rods.

Preferably, the left clamping part and the right clamping part have different specifications and models, which can be selected according to the specifications of workpieces to be processed.

Preferably, the base connection interface can be selected in different specifications to meet the connection with different types of machine tools.

The beneficial effects of the utility model are:

1. The inner side of the base of the mechanical fixture is respectively connected to the left clamp body and the right clamp body through two spring rods, the right side of the left clamp body is connected to the left clamping part, the left side of the right clamp body is connected to the right clamping part, and the clamp body and the clamping part are connected. The holders are connected by flanges. When clamping workpieces, different left and right holders can be selected according to the specifications of the workpieces. The versatility is wider and it is convenient to process workpieces of different specifications.

2. In the mechanical fixture, there are bosses on the left side of the left clamp body and the right side of the right clamp body. The screws installed on both sides of the base reach the positions of the bosses. The workpiece is clamped under the action of the lock nut; and the clamped workpiece is more stable under the action of the lock nut, and the deviation is not easy to occur during the processing.

Of course, any product implementing the present utility model does not necessarily need to achieve all the above-mentioned advantages at the same time.
