The rear end of the pressing rod 3 is rotatably connected with the rear part of the base 1 through a rotary shaft 31, the rotary axis between the pressing rod 3 and the base 1 extends in the left-right direction, and the length direction of the pressing rod 3 extends in the front-rear direction.
As shown in fig. 2 and 4, the locking mechanism includes a locking lever 4 slidably provided on the pressing lever 3, and a locking portion 5 provided on the base 1 and capable of being cooperatively connected with the locking lever 4, the locking lever 4 being connected with the locking portion 5 to lock the locking mechanism, and the locking lever 4 being disengaged from the locking portion 5 to unlock the locking mechanism.
The locking lever 4 is provided at the front of the pressing lever 3, and the axial direction of the locking lever 4 is perpendicular to the length direction of the pressing lever 3, and preferably, the locking lever 4 is provided between the left and right side portions of the U-shaped pressing lever 3. The direction of movement of the locking lever 4 is perpendicular to the axis of rotation of the compression lever 3.
The lock lever 4 has a first position and a second position by itself sliding relative to the plunger 3, and when the lock lever 4 is connected to the lock portion 5, the lock lever 4 is in the first position, and the lock lever 4 is switched to the second position by moving toward the front end of the plunger 3. The pressure lever 3 is provided with a first spring member 6 for directly or indirectly applying a force to the locking lever 4, which first spring member 6 is adapted to move the locking lever 4 from the second position to the first position or to hold the first spring member 6 in the first position. The pressing rod 3 is further provided with an unlocking member 7 in a sliding manner, and the unlocking member 7 is used for driving the locking rod 4 to slide from the first position to the second position against the force of the first elastic member 6.
