A pull block 100 is fixedly connected to the bottom left side of the locking block 13.

[0026] Specifically, when needle 8 is needed, first pull down the pull block 100. The pull block 100 drives the locking block 13 to move downward. The locking block 13 drives the slider 11 to press down the buffer spring 12, causing the locking block 13 to separate from the bottom slot 14. Then move the moving block 6 to the left. The moving block 6 drives the protective frame 4 to move to the left, causing the protective frame 4 to separate from the needle 8. Then release the pull block 100. Through the restoring force of the buffer spring 12, the surfaces of the locking block 13 and the fixing rod 5 come into contact with each other. When pulled to the left to the corresponding top slot 14, rotate the moving block 6. The moving block 6 rotates 180 degrees around the fixing rod 5, causing the protective frame 4 to rotate 180 degrees.
