One end of the pull rod 38 is fixedly connected to the surface of the displacement plate 39.

[0032] Several connecting plates 31 and arc plates 34 are arranged in pairs and linearly arrayed on the electronic circuit board 1. The displacement plate 39 is located at the bottom of the electronic circuit board 1. By designing several displacement plates 39, the electronic circuit board 1 can be combined and connected.

[0033] The displacement plate 39 is set in a semi-circular arc shape and is made of metal. There are several displacement plates 39, arranged in pairs and linearly arrayed on the electronic circuit board 1.
