As shown in fig. 2, the first jack 7 and the second jack 8 are both plate-shaped.

As shown in fig. 2 and 3, the first push rod 7 is provided with a first abutting portion 9 abutting against one end side of the key 6, the distance from the first abutting portion 9 to the rotation center of the key 6 is greater than the distance from the first push rod 7 to the rotation center of the key 6, and the outer end of the second push rod 8 abuts against the other end side of the key 6. The central axis of the first rotating shaft and the second rotating shaft 20 is the rotating center of the key 6, and when the key 6 is pulled, the key 6 rotates around the rotating center. The outer end of the first ejector rod 7 is bent towards one side far away from the rotating center of the key 6, and then bent towards the outer end to form a first abutting part 9.
