The motor drives the position of the bidirectional threaded rod to rotate through the rotating shaft at the output end. The side wall of the bidirectional threaded rod is threadedly connected to the inner wall of the main clamping plate. Therefore, when the bidirectional threaded rod rotates, it can drive the positions of the two main clamping plates to approach each other. The main clamping plate will also drive the position of the adjusting rod to move. The adjusting rod slides on the inner wall of the arc groove provided on the inner wall of the adjusting plate, effectively prompting the adjusting plates on both sides to move to the middle position, and the adjusting plate further drives the long The position of the rod and the auxiliary clamping plate moves. When the auxiliary clamping plate contacts the side wall of the gear box body, it squeezes one end of the extrusion spring until the inner wall of the main clamping plate contacts the side wall of the gear box body. The main clamping plate clamps the gear box body for stability. Under the action of the extrusion spring and the long rod, the auxiliary clamping plate can assist in stabilizing the side wall of the gear box body, effectively improving the stability of the gear box body when it is fixed, and solving the problem that the current fastening positioning device often lacks flexibility. For gear box bodies of different specifications, different clamps need to be replaced, which increases processing costs and time costs.

At this time, the L-shaped plate will slide on the side wall of the limiting rod, effectively improving the stability of the adjusting plate when moving, making it easier for operators to use the device.
