When it is necessary to install the protective bin 4, the two limit blocks 905 are pressed again. When the limit block 905 moves to a suitable position, the mounting block 6 on the protective bin 4 is moved into the mounting slot 5, and the movement of the mounting block 6 drives the limit block 905 to move. When the limit block 905 moves to the fixed cavity 901 and is connected to the limit slot 904, the spring 902 is no longer subjected to external force, and will drive the limit block 905 to be inserted into the limit slot 904, thereby completing the fixation of the limit block 905 and then completing the installation of the protective bin 4.

A vertical rod 805 is movably provided through the surface, a second transmission block 809 is fixedly connected to one side of the moving block 806, and the second transmission block 809 is fixedly connected to the outer wall close to the movable plate 12, a sliding rod 803 is provided on one side of the second transmission block 809, a sliding sleeve 801 is slidably sleeved on the outer wall of the sliding rod 803, a first transmission block 802 is fixedly connected to the other side of the sliding sleeve 801, and the first transmission block 802 is fixedly connected to the outer wall close to the movable plate 12, a connecting rod 7 is fixedly connected to the bottom of the movable plate 12, and a cutter body 10 is fixedly connected to the bottom of the connecting rod 7;

[0028] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, when in use, when the cutter body 10 needs to be used for cutting, the rotating plate 2 can be rotated, and the rotating plate 2 drives the worm 804 to rotate, and the worm 804 rotates through the worm gear 807 to drive the rotating rod 808 to rotate, and the rotating rod 808 rotates to drive the threaded rod 810 to rotate, and the threaded rod 810 rotates to drive the moving block 806 to move downward, and the moving block 806 moves downward to drive the second transmission block 809 to move downward, and the second transmission block 809 moves downward through the cooperation of the sliding sleeve 801, the first transmission block 802 and the sliding rod 803, and the movable plate 12 moves downward, and the movable plate 12 moves downward and drives the cutter body 10 to move downward through the connecting rod 7. When the cutter body 10 moves downward, When it moves to a suitable position, the rotating plate 2 stops rotating, so that the lower end of the cutter body 10 extends out of the protective bin 4, which is convenient for cutting. At the same time, through the cooperation between the worm 804 and the worm wheel 807, a self-locking effect can be achieved, which can improve the stability of the cutter during operation. Similarly, the storage of the cutter body 10 can be completed, that is, the cutter body 10 completely enters the protective bin 4, thereby achieving the purpose of protecting the cutter body 10 with the protective bin 4, and solving the problem that the spring 902 is compressed by moving the guide rod downward to drive the cutter to move downward, which is convenient for cutting later, but the spring 902 is easily deformed, which will reduce the stability of the cutter during operation and is not conducive to the normal use of the cutter.

[0029] Working principle: In the present application, the mounting plate 1 is connected to the driving part corresponding to the eyelet buttonhole machine through the fixing plate 3, and then the driving part of the eyelet buttonhole machine is used to drive the cutter body 10 to move downward, so as to implement the cutting task. In this process, the rotating plate 2 can be rotated, and the rotating plate 2 drives the worm 804 to rotate, and the worm 804 drives the rotating rod 808 to rotate through the worm gear 807, and the rotating rod 808 drives the threaded rod 810 to rotate, and the threaded rod 810 drives the moving block 806 to move downward, and the moving block 806 moves downward with The second transmission block 809 moves downward, and the second transmission block 809 moves downward, and the movable plate 12 moves downward through the cooperation of the sliding sleeve 801, the first transmission block 802 and the sliding rod 803. The movable plate 12 moves downward and drives the cutter body 10 to move downward through the connecting rod 7. When the cutter body 10 moves to a suitable position, the rotating plate 2 stops rotating, so that the lower end of the cutter body 10 extends out of the protective bin 4, which is convenient for cutting. At the same time, the worm 804 and the worm wheel 807 cooperate with each other to achieve a self-locking effect. The stability of the cutter during operation can be improved. Similarly, the storage of the cutter body 10 can be completed, that is, the cutter body 10 is completely inserted into the protective bin 4, so as to achieve the purpose of using the protective bin 4 to protect the cutter body 10. Secondly, when the protective bin 4 needs to be disassembled, the two limit blocks 905 can be pressed to move the limit blocks 905 in a direction away from the limit groove 904 and close to the fixed cavity 901. When the limit blocks 905 move to a suitable position, the protective bin 4 is moved downward until the mounting block 6 is disengaged from the mounting groove 5, thereby completing the removal of the protective bin 4. The protective bin 4 is disassembled. When the protective bin 4 needs to be installed, the two limit blocks 905 are pressed again. When the limit blocks 905 move to the appropriate position, the mounting block 6 on the protective bin 4 is moved into the mounting groove 5, and the movement of the mounting block 6 drives the limit block 905 to move. When the limit block 905 moves to the connection between the fixed cavity 901 and the limit groove 904, the spring 902 is no longer subjected to external force, and will drive the limit block 905 to be inserted into the limit groove 904, thereby completing the fixation of the limit block 905 and completing the installation of the protective bin 4.
