[0025] Specifically, the support block 41 is located on the inner wall of the assembly cavity 42 and is fixedly connected to a guide column 48. A slide groove 49 is provided on the curved surface of the force-carrying plate 43. The guide column 48 is slidably connected to the inner wall of the slide groove 49. Through the cooperation between the guide column 48 and the slide groove 49, the moving direction of the force-carrying plate 43 can be guided and the problem of rotation of the force-carrying plate 43 during use can be reduced.

[0026] Specifically, the support block 41 is in a stepped shape, the latch 45 is in a trapezoidal shape, and the trapezoidal angle of the latch 45 is located at the open end of the support block 41 .

[0027] In this embodiment, the support block 41 is configured to be stepped, so that an open end is left on one side of the support block 41 for the connection plate 47 to be placed.

[0028] Specifically, the guide column 48 is U-shaped, and there are four guide columns 48. The four guide columns 48 are arranged in a circular array about the force-carrying plate 43. The guide columns 48 are in line contact with the outer circumferential surface of the limit spring 44. By installing the four guide columns 48 around the limit spring 44, the guide columns 48 can constrain the deformation direction of the limit spring 44 during the deformation of the limit spring 44.

[0029] In this embodiment: the connecting component 5 includes a left limit frame 51, the left limit frame 51 is installed on the lower surface of the left protective cover 1, and the right limit frame 52 is installed on the lower surface of the right protective cover 2.

When the right protective cover 2 reaches the surface of the left protective cover 1, the connecting plate 47 is pushed toward the open end of the support block 41. The connecting plate 47 reaches the surface of the bayonet 45 during the rotation process, and continues to push the connecting plate 47. The connecting plate 47 pushes the bayonet 45 under the guidance of the inclined surface of the bayonet 45. The bayonet 45 is forced to push the load plate 43 upward, and the load plate 43 is forced to squeeze the limit spring 44. The limit spring 44 is squeezed and deformed to lose the constraint on the load plate 43 and the bayonet 45. The bayonet 45 loses the constraint and slides into the assembly cavity 42. When the connecting plate 47 is completely moved into the support block 4 1, the jack on the connecting plate 47 coincides with the bayonet 45, and at the same time, the connecting plate 47 loses the force applied to the bayonet 45, and the bayonet 45 loses the force applied to the load-bearing plate 43, and the load-bearing plate 43 loses the pressure applied to the limit spring 44, and the limit spring 44 loses the pressure and rebounds, and pushes the load-bearing plate 43 and the bayonet 45 to reset.
