The side of the force application column 322 is provided with a limit groove 3221, and the shape of the limit groove 3221 is the same as that of the limit convex part 51. Referring to fig. 5, when the rotation mechanism 4 forces the force-applying column 322 to turn upwards, the force-applying column 322 abuts against the swinging block 5 which naturally sags, and then the force-applying column 322 pushes the swinging block 5 to rotate upwards, and finally, when the limit protrusion 51 is located at the position corresponding to the limit groove 3221, the limit protrusion 51 can be automatically clamped in the limit groove 3221, so that the swinging block 5 and the force-applying column 322 are kept fixed.
