When the first wedge block 11 is in use, the second elastic member is reset and slides to the initial position, the first compression spring 12 is reset to the natural state, the first slide bar 10 slides to the initial position, driving the first wedge block 11 to move to the initial position together. Conversely, when in use, the protective plate 5 is driven to slide to the initial position, and the reset spring 6 is squeezed. In this process, through the transition effect of the inclined surface, the first wedge block 11 is first forced to slide to the limit position, driving the first slide bar 10 to slide to the limit position together, and the first compression spring 12 is squeezed. Then the first compression spring 12 is reset to the natural state, the first slide bar 10 slides to the initial position, driving the first wedge block 11 to move to the initial position together and plug and cooperate with the positioning hole 7. Due to the obstruction of the first wedge block 11, the protective plate 5 cannot slide.

[0033] Referring to the above, in the initial state, the connecting rod 17 is in the initial position, and the two second slide bars 14 are both in the initial position. By driving the connecting rod 17 to slide to the extreme position, the two second slide bars 14 are driven to slide to the extreme position together, so that there is no need to operate the two second slide bars 14 separately, which is more convenient to use. After that, the connecting rod 17 is released, and the two second slide bars 14 and the connecting rod 17 move to the initial position together.

When the protective cover 4 is in the extreme position, the roller 22 rolls and overlaps with the limit block 19, and then the rotating rod 20 is locked by the locking part, and the rotating rod 20 cannot be reversed, that is, the connecting rod 21, the roller 22 and the protective cover 4 all keep their positions unchanged, so as to lock the protective cover 4. Conversely, the rotating rod 20 is unlocked by the locking part, the extrusion spring 18 is reset to the natural state, the protective cover 4 slides to the initial position, and the roller 22, the connecting rod 21 and the rotating rod 20 are driven by the protective cover 4 to rotate in the opposite direction, so as to unlock the protective cover 4.

When the rotating rod 20 is driven to rotate forward, the ratchet 23 is driven to rotate together, the torsion spring 26 is repeatedly squeezed and reset, and the shaft 24 and the pawl 25 reciprocate together. When the protective cover 4 is at the extreme position, the rotating rod 20 stops rotating. At this time, the torsion spring 26 is reset to the natural state, the pawl 25 and the ratchet 23 are in contact and overlapped, and the ratchet 23 cannot be reversed due to the obstruction of the pawl 25. 23 cannot be reversed, that is, the rotating rod 20 cannot be reversed, so as to lock the rotating rod 20. On the contrary, the pawl 25 is moved away from the ratchet 23, driving the shaft 24 to rotate together, the torsion spring 26 is squeezed, and due to the loss of the obstruction of the pawl 25, the ratchet 23 and the rotating rod 20 rotate in the opposite direction together, so as to unlock the rotating rod 20. Then the pawl 25 is released, and the torsion spring 26 is reset to a natural state, and the pawl 25 and the ratchet 23 are in contact and overlapped. Due to the obstruction of the pawl 25, the ratchet 23 cannot be reversed, that is, the rotating rod 20 cannot be reversed, so as to lock the rotating rod 20 again.
