The width of the L-shaped narrow deep groove is greater than the width of the first lever by 0.5 mm. The two deep grooves of different sizes on the locking block facilitate the combined locking spring to synchronously and linkageally exert force to lock.

[0076] The locking detent pin 133 is installed in the corresponding small hole at the end of the locking block, and the detent pin reset spring sheet 134 is installed in the groove of the locking block;

[0077] The lower end of the locking deflector pin 133 is in the guide groove of the W-shaped one-way guide slider, and the movement trajectory is controlled by the curved gentle slope and steps in the guide groove. The upper end of the locking deflector pin 133 is provided with elastic force by the deflector pin reset spring sheet 134, so that the lower end of the locking deflector pin 133 is always in contact with the guide groove of the W-shaped one-way guide slider 120 and moves up, down, left and right along the curved gentle slope and steps in the guide groove.
