[0045] The locking mechanism 5 is arranged on the bottom plate 10 of the cutter 1 and is located on both sides of the sliding plate 41, and is used to lock the sliding plate 41 that slides to the replacement position. The locking mechanism 5 includes a locking head 50, a connecting rod 51, a return spring 52 and an operating head 53. The locking head 50 and the operating head 53 are provided with relatively movable grooves. One end of the connecting rod 51 can be swingably set in the movable groove of the locking head 50, and the other end can be swingably set in the movable groove of the operating head 53. A collar is arranged in the middle of the connecting rod 51, and a middle column is correspondingly arranged on the bottom plate 10. The collar is sleeved on the middle column to set the connecting rod 51 on the bottom plate 10, so that when one end of the connecting rod 51 swings inward, the other end swings outward at the same time.
