Referring to fig. 10, the unlocking member 10 has a plate shape extending in a left-right direction (for example, in the left-right direction shown in fig. 10), a protruding driving portion 101 is formed on one side of the unlocking member 10 facing the locking mechanism, a first driving surface 10111 and a second driving surface 10121 are formed on left and right sides of the driving portion 101, respectively, and when the locking mechanism 9 passes through the unlocking member 10 in an up-down direction (for example, in the up-down direction shown in fig. 9), the unlocking section 95 of the first cantilever 91 slides along the first driving surface 10111, and the unlocking section 95 of the second cantilever 92 slides along the second driving surface 10121. Therefore, the locking mechanism 9 can be switched between the locking state and the unlocking state under the action of the driving part 101 of the unlocking piece 10, and the unlocking piece 10 is simple in structure, convenient to manufacture and capable of saving production cost.

Further, as shown in fig. 10, the driving portion 101 includes a first rib 1011 and a second rib 1012 extending in the up-down direction and arranged at an interval in the left-right direction, and in the direction from the bottom up (for example, the up-down direction shown in fig. 9), the first rib 1011 and the second rib 1012 extend obliquely upward toward the direction away from each other and then extend obliquely upward toward the direction close to each other, a side surface of the first rib 1011 facing away from the second rib 1012 is formed as a first driving surface 10111, and a side surface of the second rib 1012 facing away from the first rib 1011 is formed as a second driving surface 10121. That is, the first rib 1011 extends obliquely upward in a direction away from the second rib 1012 and then extends obliquely upward in a direction close to the second rib 1012, and the second rib 1012 extends obliquely upward in a direction away from the first rib 1011 and then extends obliquely upward in a direction close to the first rib 1011. Thus, the first rib 1011 and the second rib 1012 simplify the structure of the driving part 101, and reduce the manufacturing difficulty of the driving part 101 and the use difficulty of the user.

Specifically, the distance between the upper end of the first rib 1011 and the upper end of the second rib 1012 and the distance between the lower end of the first rib 1011 and the lower end of the second rib 1012 are both smaller than the distance between the unlocking section 95 of the first cantilever 91 and the unlocking section 95 of the second cantilever 92, the first rib 1011 and the second rib 1012 are bilaterally symmetrical, and the first rib 1011 and the second rib 1012 are vertically symmetrical. It can be understood that the distance between the upper end of the first rib 1011 and the upper end of the second rib 1012 is smaller than the distance between the unlocking section 95 of the first cantilever 91 and the unlocking section 95 of the second cantilever 92, and the distance between the lower end of the first rib 1011 and the lower end of the second rib 1012 is also smaller than the distance between the unlocking section 95 of the first cantilever 91 and the unlocking section 95 of the second cantilever 92.

When locking mechanism 9 reciprocates through unlocking piece 10, the upper end of first protruding muscle 1011 and the upper end of second protruding muscle 1012, can stretch into easily between the unblock section 95 of the first cantilever 91 of locking mechanism 9 and the unblock section 95 of second cantilever 92, or first protruding muscle 1011 lower extreme and the second protruding muscle 1012 lower extreme, also can stretch into easily between the unblock section 95 of the first cantilever 91 of locking mechanism 9 and the unblock section 95 of second cantilever 92, therefore, locking mechanism 9 and unlocking piece 10's cooperation simple structure, locking mechanism 9 is more convenient at the switching between locking state and the unlocking state, and the user is laborsaving when the operation.
