In addition, when the tool holder 110 clamps the tool 200, the first clamping piece and the second clamping piece approach each other along the first direction, so as to clamp the tool 200, and then the spindle 100 drives the tool 200 to move away from the tool holder 310 along the second direction, at this time, the tool 200 is separated from the tool holder 310, and an acting force with the same direction as the spindle 100 is applied to the tool holder 310, and an acting force opposite to the spindle 100 is applied to the tool holder 310 due to the acting force of the elastic piece 320, so that an inertial force of the tool holder 310 along the spindle 100 is buffered, and the tool holder 310 is protected.
Preferably, the clamping and loosening of the tool 200 by the tool holder 110 is controlled pneumatically. The pneumatic control is the prior art, and therefore, will not be described herein.
