[0061] It can be understood that the movable chuck 2 and the fixed chuck 1 in the embodiment are rotationally connected, and the movable chuck 2 can gradually approach the fixed chuck 1 when the user applies force to the driving assembly 3. Specifically, when the user wants to clamp an object, the user only needs to rotate the driving block 33. It should be understood that the driving block 33 can extend in the radial direction of the driving rod 32 to form at least one rotating handle.
