The sliding block 14 is also fixedly connected to the connecting plate 5, which plays a limiting role on the connecting plate 5, preventing the connecting plate 5 from rotating along with the double-threaded rod 4 during the rotation process, so that it cannot play a role of lateral translation;

The two connecting plates 5 adjust the distance and orientation of the two connecting rods 9 and the contact block 10. Through the elasticity of the first telescopic spring 16, the first telescopic spring 16 pushes the round head block 17 to engage with the semicircular groove 18, so that the connecting rod 9 can be locked and fixed in a specific position of the sliding hole 8.
