When the maximum clamping range of the adjustable bracket is larger than that of the workpiece 40, the sliding rail 20 is moved to move the clamping device 30 to the position above the workpiece 40, the handle 1 is continuously rotated, and at the moment, the adjustable bracket is contracted to clamp the workpiece 40. When the workpiece 40 needs to be loosened, the handle 1 is continuously rotated anticlockwise, the adjustable bracket cannot contract at the moment due to clamping of the workpiece 40, when the telescopic rod 8 is in a continuous extension state when the workpiece 40 is clamped, the third gear 91 provides a pushing force for the rack 10 in the radial direction outwards, and therefore the compression spring 11 cannot be compressed at the moment, in the continuous rotation process, the torsion spring 7 stores a torsional force, when the telescopic rod 8 is in a continuous shortening state when the workpiece 40 is clamped, the third gear 91 provides a pulling force for the rack 10 in the radial direction inwards, and therefore the compression spring 11 is compressed at the moment, the rack 10 moves inwards along the tooth grooves 31, and the torsion spring 7 does not deform. After continued rotation past the minimum grip range of the adjustable support for one rotation cycle, the adjustable support begins to expand, thereby releasing the workpiece 40 during continued rotation.
