[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention ensures that all wear occurs on the two force-bearing movable blocks, thereby increasing the service life of the tool handle mounting seat. The provision of two positioning pins plays an elastic positioning role on the two force-bearing movable blocks, making the two force-bearing movable blocks more stable after being connected to the tool handle mounting seat.

[0020] 2. In the present invention, when the tool handle mounting seat does not shake after installation, the two circular metal blocks are connected under the conductive effect of the CNC lathe cutter disc, so that the buzzer continues to work. When the tool handle mounting seat shakes after installation, the front sides of the two circular metal blocks do not contact or intermittently contact the CNC lathe cutter disc, so that the buzzer does not work or works intermittently. The staff can judge the degree of wear of the two force-bearing movable blocks and the screws on the CNC lathe cutter disc according to the working state of the buzzer, which is convenient for the staff to replace the two force-bearing movable blocks and the screws on the CNC lathe cutter disc in time, thereby ensuring the processing accuracy of the workpiece;

[0021] In addition, when the screw on the CNC lathe tool disc continues to move downward and contacts the two linked reset rods, the screw on the CNC lathe tool disc pushes the two linked reset rods to move. At this time, the support spring B is compressed, and the rectangular insulating block drives the two circular metal blocks to move inward for a distance, so that the two circular metal blocks are separated from the CNC lathe, and the buzzer stops working.

[0022] 3. The present invention makes it convenient for the staff to tighten the compression thread block by using a hexagonal wrench. The arrangement of the six balls reduces the degree of wear on the bottom of the compression thread block. When the staff loosens the compression thread block by using a hexagonal wrench, the tool handle compression block moves upward under the action of the two reset springs C.

[0023] 4. In the present invention, when the bottom of the L-shaped anti-loosening plate contacts the clamping thread block, the tool handle in the tool handle mounting seat is in a locked state, which limits the clamping thread block and avoids loosening of the clamping thread block, thereby improving the locking effect of the tool handle. When the clamping thread block is tightened, the L-shaped anti-loosening plate automatically moves under the action of two reset springs D, and the clamping thread block has reached the specified locking position. Under the premise of ensuring the locking effect, the wear and damage between the tool handle and the tool handle clamping block are reduced. BRIEF DESCRIPTION OF THE DRAWINGS

When the tool holder mounting seat 101 does not shake after installation, the two circular metal blocks 207 are connected under the conductive effect of the CNC lathe tool disc, so that the buzzer 206 continues to work. When the tool holder mounting seat 101 shakes after installation, the front sides of the two circular metal blocks 207 do not contact or intermittently contact the CNC lathe tool disc, so that the buzzer 206 does not work or works intermittently.

[0051] Its specific function is: because the clamping thread block 305 is threadedly connected to the tool handle mounting seat 101, and a hexagonal groove is provided on the top of the clamping thread block 305, it is convenient for the staff to tighten the clamping thread block 305 with a hexagonal wrench. The setting of the six balls 306 reduces the degree of wear on the bottom of the clamping thread block 305. Because the two reset springs C304 are installed on the outside of the two circular guide rods 301, and the two reset springs C304 are located between the tool handle mounting seat 101 and the two reset clamps B303, when the staff loosens the clamping thread block 305 with a hexagonal wrench, the tool handle clamping block 302 moves upward under the action of the two reset springs C304.

When the tool handle mounting seat 101 does not shake after installation, the two circular metal blocks 207 are connected under the conductive effect of the CNC lathe tool disk, so that the buzzer 206 continues to work. When the tool handle mounting seat 101 shakes after installation, the front sides of the two circular metal blocks 207 are connected to the tool disk of the CNC lathe. The tool disc of the CNC lathe is not in contact or is in intermittent contact, so that the buzzer 206 does not work or works intermittently. The staff can judge the wear degree of the two force-bearing movable blocks 102 and the screws on the tool disc of the CNC lathe according to the working state of the buzzer 206, which is convenient for the staff to replace the two force-bearing movable blocks 102 and the screws on the tool disc of the CNC lathe in time, thereby ensuring the processing accuracy of the workpiece; when the screw on the tool disc of the CNC lathe continues to move downward and contacts the two linked reset rods 203, the screw on the tool disc of the CNC lathe pushes the two linked reset rods 203 to move. At this time, the support The support spring B204 is compressed, and the rectangular insulating block 201 drives the two circular metal blocks 207 to move inward for a distance, so that the two circular metal blocks 207 are separated from the CNC lathe, and the buzzer 206 stops working; then the staff inserts the tool handle into the tool handle mounting seat 101, and then tightens the clamping thread block 305 through the hexagonal screw. The setting of the six balls 306 reduces the wear degree of the bottom of the clamping thread block 305.
