Wherein, during the deformation process of the elastic member 70 , it will also drive the displacement of the second limiting member 60 .

When an external force acts on the operating portion 41 of the handle 40 in any direction perpendicular to the Z-axis direction and except the X-axis direction and the Y-axis direction, since the fixed portion 45 of the handle 40 is fixedly connected to the first limiting member 50, the second A limiter 50 and the handle 40, the swing fulcrum is located between the operation part 41 and the fixed part 45, the first limiter 50 moves in the opposite direction of the action direction, the first limiter 50 is connected with the first opening 1332, the second The mutual cooperation of the opening 1372 and the first gap 535 makes the first limiting member 50 have a movable space in the XY plane, so the handle 40 can swing along the action direction. When the external force is lost, the elastic member 70 recovers to deform, and the first limiting member 50 returns to the original position under the action of the elastic member 70 and at the same time drives the handle 40 to return to the original position. Wherein, during the deformation process of the elastic member 70 , it will also drive the displacement of the second limiting member 60 .
