Specifically, as shown in fig. 3, the cover body 2 is provided with a mounting frame 21 at the hinge joint, the mounting frame 21 is provided with a through hole 22, and the rotating shaft 3 is inserted into and penetrates through the through hole 22, so as to fix the rotating shaft 3 on the cover body 2. As shown in fig. 4, the support ring of the base 1 forms a support frame 11 at the hinge joint, the support frame 11 forms a notch 12, two ends of the shaft 3 are mounted in the notches 12, and the shaft 3 can rotate in the notches 12 to rotate the cover 2 relative to the base 1.

As shown in fig. 5, in order to switch the fixing and separating states of the cover 2 and the base 1, the supporting ring of the base 1 is provided with a rotatable switch 4, the switch 4 is formed with a hook 41, and the hook 41 extends to the side of the rotating shaft 3. As the switch 4 rotates, the hook 41 swings with the switch 4. When the switch 4 rotates in the forward direction, the hook 41 hooks the side of the rotating shaft 3 away from the notch 12 to prevent the rotating shaft 3 from coming off from the notch 12, the rotating shaft 3 is limited in a space enclosed by the inner wall of the notch 12 and the hook 41, and the rotating shaft 3 can rotate in the space, so that the cover 2 rotates relative to the base 1. When the switch 4 is rotated reversely, the hook 41 is disengaged from the shaft 3, so that the shaft 3 can be moved out of the notch 12, and the notch 12 is disposed on the base 1 and the shaft 3 is disposed on the cover 2, thereby separating the base 1 and the cover 2.

The specific rotation of the forward rotation and the reverse rotation depends on the position of the hook 41 relative to the rotation shaft 3. The hook 41 is located on the counterclockwise side of the rotating shaft 3, and the forward rotation is clockwise rotation, and the reverse rotation is counterclockwise rotation. Of course, the hook 41 may be located on the clockwise side of the rotating shaft 3, and the forward rotation is counterclockwise rotation, and the reverse rotation is clockwise rotation.

Referring to fig. 6 and 7, in order to make the switch 4 rotatable, the switch 4 is formed with a shaft body 42, the support ring of the base 1 is provided with symmetrically arranged stud holes 13, and the stud holes 13 are used for inserting two ends of the shaft body 42, so that the switch 4 is rotatably connected with the support ring of the base 1. And the opening of the rotary column hole 13 is formed with a guide notch 14 extending to the edge of the base 1, and the shaft body 42 is inserted into the rotary column hole 13 along the guide notch 14.

In order to reset the switch 4, an elastic member is clamped between the switch 4 and the support ring of the base 1, and the elastic member drives the switch 4 to rotate, so that the hook 41 swings and hooks the rotating shaft 3. Specifically, the elastic member is a return spring 5. In order to install the return spring 5, a collar 16 is formed on the support ring of the base 1, a cross-shaped positioning rib 44 is formed on the change-over switch 4, one end of the return spring 5 is sleeved in the collar 16, and the other end of the return spring is sleeved outside the positioning rib 44, so that the return spring 5 is installed and fixed.

The end of the hook 41, i.e., the end of the latch 412, is formed with a guide angle 413, the guide angle 413 is abutted by the rotating shaft 3 inserted into the notch 12, and the tangential component of the pressure applied to the guide angle 413 by the rotating shaft 3 causes the hook 41 to press the return spring 5 and rotate, so that the rotating shaft 3 is inserted into the space enclosed by the notch 12 and the hook 41. Then, the reset spring 5 drives the switch 4 to reset, and the hook 41 hooks the rotating shaft 3 to prevent the rotating shaft 3 and the base 1 from separating.

Hinge spring 6 is sleeved outside rotating shaft 3, first torque arm 61 and second torque arm 62 are respectively formed at two ends of hinge spring 6, first torque arm 61 is fixed with base 1, and second torque arm 62 is fixed with cover 2, so that cover 2 has an automatic cover opening function.
