In contrast, in the conventional pull-back collet chuck 10 shown in fig. 1, the pull-back strength is related to the area of the action surface 111 of the piston 11, and the pull-back strength is small when the area of the action surface 111 is small, and the pull-back strength is large when the area of the action surface 111 is large. Therefore, the minimum area of the active surface 111 of the existing pull-back collet chuck 10 must meet the effective clamping strength under the limitation of the effective clamping strength, resulting in the fact that the outer diameter of the existing pull-back collet chuck 10 must be large enough to accommodate the large area of the active surface 111. However, the number of the collet chucks which can be placed on the workbench is much smaller, and the collet chucks need to be locked by screws so as not to rotate, so that the total height of the existing rear pull type collet chuck 10 is increased by a large amount, and the existing rear pull type collet chuck 10 is long and thick. There is thus considerable room for improvement.
