The adjusting bolt is screwed with two locking nuts, one locking nut is used for locking the adjusting bolt and the lifting shaft 43, and the other locking nut is used for locking the adjusting bolt and the fixing sleeve 51.

Specifically, when the work is clamped using the rotating jig, the adjusting bolts are first rotated according to the specifications of the work to be screwed in or out with respect to the lifting shaft 43, and then the two locking bolts 21 are locked. And the supporting seat is rotated to enable the clamping assembly 5 to leave the position right above the workpiece mounting position, and the workpiece is placed. The support base is rotated again so that the clamping assembly 5 is located directly above the workpiece, and the handle 41 is pulled downward so that the ram 53 presses against the workpiece, thereby making good contact between the workpiece and both the base 1 and the test PCB 100. After the workpiece is tested, the handle 41 is pulled upwards to enable the pressure head 53 to be out of contact with the workpiece, the supporting seat is rotated to enable the clamping assembly 5 to be away from the position right above the workpiece, the workpiece is taken out, and the above actions are repeated to circularly clamp and test other workpieces.

The rotary clamp in the embodiment is simple and convenient to operate and wide in application range. And the actions of all the moving parts in the use process are controllable, so that the safety in the use process is higher, and the injury to a user is avoided. Meanwhile, the problem of collision damage in the workpiece taking and placing process due to insufficient space for taking and placing the workpieces is effectively solved.
