[0051] Further, the lifting assembly 203 includes a collar 203a disposed above the sleeve column 201, movable grooves 203b disposed on both sides of the sleeve column 201, a movable frame 203c disposed on the collar 203a and matched with the movable grooves 203b, and a rotating plate 203d disposed between the movable frame 203c and the limit slider 202a-2. The bottom of the collar 203a contacts the top of the sleeve column 201, the collar 203a is sleeved on the outer surface of the vertical rod 102, and the inner surface of the collar 203a does not contact the outer surface of the vertical rod 102, the bottom of the collar 203a and both sides of the sleeve column 201 are fixedly connected with movable frames 203c matched with the movable grooves 203b, the top of the rotating plate 203d is rotatably connected to the bottom of the movable frame 203c through a rotating member, and the bottom of the rotating plate 203d is rotatably connected to the top of the limit slider 202a-2 through a rotating member.

[0052] Furthermore, the lifting assembly 203 also includes a fixing ring 203e arranged on the vertical rod 102, an annular groove 203e-1 arranged on the outer surface of the fixing ring 203e, and an annular frame 203e-2 arranged inside the annular groove 203e-1, and two limiting rods 203e-3 penetrating the annular frame 203e-2 are arranged on the collar 203a, and a return spring 203e-4 is arranged between the top of the outer surface of the limiting rod 203e-3 and the annular frame 203e-2. Among them, the fixing ring 203e is sleeved and fixed on the outer surface of the vertical rod 102, the fixing ring 203e is located between the rotating column 204c and the collar 203a, and the annular groove 203e-1 and the annular frame 203e-2 are slidably connected.

[0053] Furthermore, the driving assembly 204 includes a motor 204a disposed inside the box 101, a position-limiting rotating groove 204b disposed at the bottom of the box 101, a rotating column 204c disposed at the periphery of the vertical rod 102 and adapted to the position-limiting rotating groove 204b, and a driven gear 204d disposed on the rotating column 204c. The output end of the motor 204a penetrates the box 101 and is fixedly connected to a driving gear 204e meshing with the driven gear 204d. The bottom of the motor 204a is fixedly connected to the bottom of the inner wall of the box 101, the driven gear 204d is sleeved and fixedly connected to the top of the outer surface of the rotating column 204c, and the bottom of the rotating column 204c is provided with an arc section, so that the rotating column 204c is in a state where one side is low and the other side is high.

[0054] Furthermore, the limiting assembly 205 is provided with a limiting block 205a on the collar 203a, and a limiting groove 205b provided on the limiting block 205a and matched with the rotating column 204c, and the back of the limiting block 205a is provided as an inclined surface. The limiting block 205a is fixedly connected to one side of the collar 203a, and the top of the limiting block 205a is higher than a part of the collar 203a, and the bottom thereof is also lower than a part of the collar 203a. By providing the back of the limiting block 205a as an inclined surface, when the rotating column 204c rotates to the limiting block 205a, it is convenient for it to move along the inclined surface of the limiting block 205a to the limiting groove 205b.

[0055] When in use, the driving motor 204a drives the driving gear 204e to rotate counterclockwise, and drives the driven gear 204d and the rotating column 204c to rotate clockwise, so that the lower end of the rotating column 204c rotates from the left to the right. Since the back of the limiting block 205a is provided with an inclined surface, when the lower position of the rotating column 204c rotates to the right, it will gradually squeeze the ring 203a and the limiting block 205a downward along the inclined surface until the lower end of the rotating column 204c is in the limiting groove 205b, and the ring 203a is squeezed. The process of pressing and moving downward will drive the movable frame 203c to move downward in the movable groove 203b, and then drive the rotating plate 203d to rotate, pushing the sliding block to move in the limiting sliding groove 202a-1 toward a position away from the sleeve column 201. The movement of the sliding block will drive the tooth plate 202a-3 to move synchronously, and then drive the rotating gear 202d to rotate, so that the rotating shaft of the rotating frame 202b and the cleaning strip 202c are synchronously rotated downward until the two cleaning strips 202c are just in contact with the two sides of the camera body 104.

[0056] When the cleaning strip 202c rotates to fit the camera body 104, the motor 204a continues to rotate counterclockwise, driving the rotating column 204c to push the limit block 205a to rotate 360 ​​degrees clockwise, so that the cleaning strip 202c rotates around the camera body 104 for one circle, and the dust and impurities on its surface are completely removed. When the rotating column 204c drives the cleaning strip 202c to rotate for one circle, the motor 204a is controlled to rotate in the opposite direction, so that the rotating column 204c rotates from the right side to the left side, until the rotating column 204c is separated from the limit groove 205b and the limit block 205a. 205a and rotates to its initial state. When the rotating column 204c is separated from the limit block 205a, the limit block 205a, the ring 203a and the movable frame 203c will be moved upward back to the original position by the elastic force of the reset spring 203e-4. The upward movement of the movable frame 203c will pull the rotating plate 203d to rotate, so that the sliding block and the tooth plate 202a-3 move toward a position close to the sleeve column 201, and then the rotating gear 202d and the cleaning strip 202c will rotate upward and be above the camera body 104 to avoid blocking it.

[0057] The remaining structure is the same as that of Example 2.
