[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0021] like Figures 1 to 4 As shown, a quick-install wear-resistant double-ended ball cutter with a clamping structure includes a clamping member 1, a mounting rod 2 is installed inside the clamping member 1, and a quick-release mechanism for quickly releasing the ball cutter is provided on the outer surface of the clamping member 1;

[0022] The quick-release mechanism includes a limit rod 3, which is mounted on the outer surface of the clamping member 1. The outer surface of the limit rod 3 is provided with a tension spring 31 that is connected to the outer wall of the clamping member 1. The end of the limit rod 3 is plugged into a limit hole 34 provided on the mounting rod 2. Two clips 32 are fixed to the inner wall of the clamping member 1. The insides of the two clips 32 are slidably connected to a slot 33 fixedly connected to the mounting rod 2. Both ends of the mounting rod 2 are connected to the tool handle 4. The staff can manually pull the limit rod 3 on the clamping member 1 so that the end of the limit rod 3 and the mounting rod 2 are in contact. The upper limit hole 34 of the mounting rod 2 is separated, releasing the fixation of the mounting rod 2. At the same time, the pulling block on the limiting rod 3 drives the fixedly connected tension spring 31 to move. With the cooperation of the clamping strip 32 and the clamping groove 33, the mounting rod 2 can be taken out of the clamping part 1. Then, the other end of the mounting rod 2 is placed outside and inserted into the clamping part 1 again, and the limiting rod 3 is loosened. Under the action of the tension of the tension spring 31 itself, the mounting rod 2 can be driven to return to the limiting hole 34, thereby limiting and fixing the mounting rod 2, which is convenient for quick disassembly and assembly and easy to use. Example 2

[0023] In addition to all the technical features of Example 1, this embodiment also includes: one end of the two tool handles 4 is fixed with a connecting block 6 that is plugged into the mounting rod 2, the outer wall of the mounting rod 2 is equipped with two fixing bolts 5 that are abutted against the connecting block 6, the ends of the two tool handles 4 are provided with a cutting mechanism for processing the workpiece, the cutting mechanism includes a blade 7, two blades 7 are provided, and the two blades 7 are installed at the ends of the two tool handles 4, the outer walls of the two blades 7 are fixed with a limiting block 71, the outer surface of the limiting block 71 is plugged into a limiting groove 72 opened on the tool handle 4, the side walls of the two blades 7 are coated with a wear-resistant coating 73, the outer wall of the tool handle 4 is equipped with two fixing screws 74 that are threadedly connected to the blade 7, by unscrewing the fixing bolts 5 on the mounting rod 2, the fixation of the connecting block 6 can be released, so that the tool handle 4 can be removed from the mounting rod 2 for easy maintenance, and by unscrewing the fixing screws 74, the blade 7 can be disassembled with the cooperation of the limiting block 71 and the limiting groove 72, and then the blade 7 can be replaced.

[0024] Working principle: Before using the quick-install wear-resistant double-headed ball cutter with a clamping structure, first connect and fix the clamping part 1 and the output shaft of the machine tool. When in use, the machine tool drives the ball cutter to rotate, thereby driving the blade 7 on the handle 4 to rotate to process the workpiece, and the wear-resistant coating 73 applied on the blade 7 can have a good wear-resistant effect. When the ball cutter needs to be replaced, the staff can manually pull the limit rod 3 on the clamping part 1 to separate the end of the limit rod 3 and the upper limit hole 34 of the mounting rod 2, thereby releasing the fixation of the mounting rod 2. At the same time, the pull block on the limit rod 3 drives the fixedly connected tension spring 31 to move, and with the cooperation of the clamping strip 32 and the clamping slot 33 , the mounting rod 2 can be taken out of the clamping part 1, and then the other end of the mounting rod 2 is outside and inserted into the clamping part 1 again, and the limiting rod 3 is loosened. Under the action of the tension of the tension spring 31 itself, the mounting rod 2 can be driven to reset and inserted into the limiting hole 34, thereby limiting and fixing the mounting rod 2, which is convenient for quick disassembly and assembly, and easy to use. By unscrewing the fixing bolt 5 on the mounting rod 2, the fixation of the connecting block 6 can be released, so that the knife handle 4 can be removed from the mounting rod 2, which is convenient for maintenance. By unscrewing the fixing screw 74, the blade 7 can be disassembled with the cooperation of the limiting block 71 and the limiting groove 72, and then the blade 7 can be replaced.
