And when the first driving piece 20 is an electromagnetic valve, the armature of the electromagnetic valve can move under the action of external force in the non-energized state, namely when the second driving piece drives the sliding block to move upwards, the clamping plate 311 drives the armature of the electromagnetic valve to move upwards.

In other embodiments, the first driver 20 is configured to be self-locking, i.e., the solenoid valve is configured such that the armature cannot move under external force. Therefore, the second driving member cannot normally push the sliding plate to move. Therefore, in this design, the output shaft of the first driving member 20 is detachably connected to the bending portion 31. That is, when the first driving member 20 cannot drive the sliding plate 30 to move along the vertical direction, the output shaft of the first driving member 20 is separated from the bending portion 31, so that the sliding plate 30 can be driven to move by the second driving member, and the influence on the operation of the second driving member is avoided.
