By adding the structure of the compression bar 4 acting on the elastic piece 3, when the first balance bar 1 and the second balance bar 2 are pressed down to swing down, the elastic piece 3 is transversely stretched to generate transverse elastic deformation, meanwhile, the downward acting force is applied to the elastic piece 3 along with the downward moving compression bar 4, so that the elastic piece 3 is longitudinally stretched to generate longitudinal elastic deformation, and therefore, the elastic piece 3 has transverse and longitudinal elastic deformation at the same time, and the elastic deformation amount is obviously increased, as shown in fig. 5; when the pressing of the first balance bar 1 and the second balance bar 2 is released, the acting force exerted by the pressing bar 4 on the elastic member 3 also disappears, at this time, the elastic member 3 can provide a larger resilience force, and the first balance bar 1 and the second balance bar 2 quickly and accurately move upwards and reset under the action of the larger resilience force of the elastic member 3, as shown in fig. 4.

Specifically, the pressing rod 4 is recessed to form the downward protruding portion 41. The downward convex action part 41 on the lower end surface of the compression bar 4 is structurally designed to directly act on the elastic piece 3, so that the accuracy of action on the elastic piece 3 is improved, the elastic piece 3 can be stretched longitudinally to generate longitudinal elastic deformation, the elastic deformation amount is increased, and the resilience force is increased.

In order to make the elastic member 3 elastically deformed in the longitudinal direction better, the downward convex action portion 41 in this embodiment is located in the middle of the compression bar 4 and acts on the middle of the elastic member 3. Therefore, the elastic piece 3 is elastically deformed downwards in the middle part, so that the elastic deformation quantity can be increased, and the resilience force can be increased.
