[0005] Preferably, a spring is connected to the lower side of the block, and an auxiliary plate is connected to the lower side of the spring.

[0006] Preferably, a guide chamfer is provided on the upper side of the clamping block.

[0007] Preferably, a handle is connected to the upper side of the circular rotating plate, and a sliding groove matching the handle is provided on the upper side of the bolt head.

[0008] Preferably, sockets are provided on both the left and right sides of the rotating plate.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. By setting the rotating plate, the circular rotating plate and the clamping block, when the position where the device contacts the screwdriver is damaged, the device can be replaced by replacing the rotating plate, thereby improving the stability of the device;

[0011] 2. By setting up the auxiliary plate and the spring, the rotating plate is attached to the lower side of the circular rotating plate during daily use, so that the upper side of the circular rotating plate contacts the bolt head, and the friction generated by the circular rotating plate and other objects is used to reduce the inconvenience of the circular rotating plate's own rotation, thereby avoiding the inability to replace the rotating plate due to the circular rotating plate's own rotation, thereby indirectly improving the stability of the device.
