A first abdicating groove 10 is arranged in the first fixing part 1, and a first rotating shaft 11 which is vertically arranged is arranged in the first abdicating groove 10. The top surface and the bottom surface of the first abdicating groove 10 are respectively provided with a limiting device 5, and the two limiting devices 5 are arranged up and down symmetrically. The limiting device 5 comprises a limiting block 51 arranged in the first yielding groove 10 and a guide post 52 arranged on the first end portion 21, an arc-shaped guide groove 50 is formed in the limiting block 51, and the guide post 52 is inserted into the arc-shaped guide groove 50. The limiting block 51 is provided with a first damping device 6 on one side facing the first abdicating groove 10.

The first end portion 21 and the two limit blocks 51 are sleeved on the first rotating shaft 11, and the first end portion 21 is located between the two limit blocks 51. The first friction portion 41 always abuts against the first damper device 6. Preferably, the limiting block 51 and the first rotating shaft 11 are detachably connected in the first avoiding groove 10 by a screw or a pin. The guide post 52 is provided at the connecting position of the first section 23 and the second section 24. The arc length of the arc-shaped guide groove 50 is just such that the rotation angle a of the coupling part 2 around the inside of the first fixing part 1 is 0-90. The limiting block 51 is an arc surface on one side facing the first abdicating groove 10, the first damping device 6 is a first friction layer 60 detachably connected to the arc surface, and the first friction layer 60 covers the arc surface.
