The auxiliary block 1 302c and the auxiliary block 2 302d are fixedly connected to the side wall of the mounting groove 302a through a torsion spring 302e. The first and second auxiliary blocks 302c and 302d are respectively formed with arc plates 302f in one piece. Therefore, when the arc portion 301b on the insert block 301a is pressed into the clamping space 302h, the first and second auxiliary blocks 302c and 302d on the arc plates 302f are driven to rotate in opposite directions. At this time, the torsion spring 302e is deformed. When the arc portion 301b on the insert block 301a completely enters the clamping space 302h, the torsion spring 302e drives the first and second auxiliary blocks 302c and 302d to rotate in opposite directions.

[0060] Working principle: It can be seen from Example 2 that before installing the movable blade 107, first pull the arc plate 203d downward to cause the tension spring 203c to deform. At this time, the arc plate 203d drives the locking portion 204a to move downward, and then the movable blade 107 is inserted into the movable hole 103. At this time, the movable blade 107 is preliminarily positioned by the positioning mechanism. Specifically, when the arc portion 301b on the plug block 301a correspondingly presses into the clamping space 302h, the auxiliary block 1 302c and the auxiliary block 2 302d on the clamping arc plate 302f are driven to rotate in the opposite direction. At this time, the torsion spring 302e is deformed. When the arc portion 301b on the plug block 301a completely enters the clamping space 302h, the auxiliary block 1 302c and the auxiliary block 2 302d are driven to rotate towards each other under the action of the torsion spring 302e, so that the two groups of clamping arc portions wrap the plug block 301a, thereby positioning the movable blade 107.
