The gimbal base 1 has a fixed tooth 5, and the ends of the fixed tooth 5 and the movable tooth 4 are provided with concave and convex steps 51. The end of the screw 3 is connected to a knob 31, which protrudes outside the gimbal cover 2. The knob 31 has a corner part 32 inside, and the screw 3 has a corner part 33. In this embodiment, the corner part and the corner part are hexagonal. The shape and size of the corner part 33 and the corner part 32 correspond to each other so that they can be tightly joined, and it is convenient to turn the screw 3 using the knob 31.

[0017] Both the through cavity 21 and the movable tooth 4 are provided with teeth 41. The teeth 41 of the movable tooth 4 are located on its outer end face. The movable tooth 4 is placed in the through cavity 21 so that the teeth 41 of the two mesh to restrict the rotation of the movable tooth 4 relative to the through cavity 21. The screw 3 is threadedly connected to the movable tooth 4. The end of the screw 3 is provided with a thread 34. The center of the movable tooth 4 is provided with a screw hole 42. The rotating screw 3 drives the movable tooth 4 to move along the through cavity 21, so that the concave and convex steps 51 of the fixed tooth 5 and the movable tooth 4 are engaged to control the locked or open state of the gimbal base 1 and the gimbal flip cover 2.

[0018] The gimbal base 1 has an outer sleeve 6, and the outer sleeve 6 has an access cavity 61. The access cavity 61 has a first slot 62, and the outer end face of the fixing tooth 5 has a first protrusion 52. The fixing tooth 5 is inserted into the access cavity 61, and the first protrusion 52 is connected to the first slot 62 so that the outer sleeve 6 and the fixing tooth 5 can rotate together. The fixing tooth 5 and the outer sleeve 6 are both provided with corresponding holes for the screw 3 to pass through.

[0019] The cavity 21 includes a first cavity section 22, a spacer 23, and a second cavity section 24. The screw 3 passes through the first cavity section 22, the second cavity section 24, and the third cavity section 21. The end of the screw 3 extends into the second cavity section 24. The spacer 23 is located between the first cavity section 22 and the second cavity section 24. The outer kit 6 of the gimbal base 1 is connected to the spacer 23.

[0020] The second cavity section 24 houses a mating member 7. The outer end face of the mating member 7 has a second protrusion 71, and the second cavity section 24 has a second retaining groove 25. The second protrusion 71 connects to the second retaining groove 25 to restrict the rotation of the mating member 7 within the second cavity section 24, allowing the mating member 7 to move only up and down along the second cavity section 24. The mating member 7 has a cavity 72 that extends through it, and the teeth 41 of the through cavity 21 are located within the cavity 72.

[0021] The gimbal cover 2 is provided with a positioning hole 26, which is connected to the first through cavity section 22. A positioning screw 27 is screwed into the positioning hole 26. The screw 3 is provided with an annular groove 35. The positioning screw 27 is inserted into the annular groove 35 to limit the position of the screw 3 in the through cavity 21 and prevent the screw 3 from falling off. The depth of the annular groove 35 is the range of adjustment of the screw 3. The screw 3 can only rotate in the through cavity 21 and cannot move up and down along the through cavity 21.

[0022] Operating principle: Since the second protrusion 71 and the second slot 25 are connected, the docking piece 7 can only move up and down along the second through cavity 21; the teeth 41 of the docking piece 7 and the movable tooth 4 are engaged, and the teeth 41 of the docking piece 7 and the movable tooth 4 are both designed vertically, so the docking piece 7 and the movable tooth 4 cannot rotate relative to each other. Therefore, the movable tooth 4 moves up and down along the cavity 72 of the docking piece 7; the first protrusion 52 and the first slot 62 are connected, and the fixed tooth 5 and the outer sleeve 6 cannot rotate relative to each other. The screw 3 and the movable tooth 4 are connected by a thread 34. By rotating the screw 3, the movable tooth 4 is restricted from rotating, so the movable tooth 4 moves up and down along the mating part 7. Both the movable tooth 4 and the fixed tooth 5 are provided with concave and convex steps 51. Rotating the screw 3 drives the movable tooth 4 to move upward. When the two concave and convex steps 51 are engaged, the gimbal base 1 and the gimbal flip cover 2 are locked and cannot be flipped relative to each other. Rotating the screw 3 drives the movable tooth 4 to move downward. When the two concave and convex steps 51 are separated, the gimbal base 1 and the gimbal flip cover 2 are unlocked and can be flipped relative to each other.

[0023] The direction of the thread 34 of both the screw 3 and the movable tooth 4 is determined according to actual needs. In this embodiment, the unlocked state and the locked state are achieved by rotating the screw 3 clockwise and counterclockwise. The angle of the concave and convex steps 51 is set to 90 degrees, so that the gimbal flip cover 2 and the gimbal base 1 can rotate 90 degrees relative to each other.
