The lifting assembly 10 includes a screw 11, a guide rod 12, a carrier 13 and a driver 14. The screw 11 and the guide rod 12 are arranged in parallel, the guide rod 12 is provided with at least one, and the carrier 13 is provided with threaded holes and at least one guide hole. The screw holes allow the screw rods 11 to pass through and are screwed together with the screw rods 11. Each guide rod 12 passes through a guide hole respectively. The diameter of the guide holes matches the rod diameter of the guide rods 12. The driver 14 drives the screw rod 11 to rotate to make the stage 13 moves along the guide rod 12. In the illustrated structure, there are two guide rods 12 located on both sides of the screw rod 11. The two guide rods 12 jointly limit the radial movement and rotation of the carrier 13, which is beneficial to reduce the radial force of the screw rod 11 and achieve protection. Effect of screw 11. The diameter of the guide hole matches the diameter of the guide rod 12 , so as to avoid the shaking of the stage 13 in the horizontal direction, which is beneficial to the smooth movement of the camera. In other embodiments, a linear bearing may be arranged between the guide rod 12 and the carrier 13 to reduce the sliding friction force between the guide rod 12 and the carrier 13 .

The connecting structure 20 is used for installing and fixing the camera, and is rotatably connected to the carrier 13 . The rotation axis between the connecting structure 20 and the carrier 13 is parallel to the guide rod 12 . The stage 13 moves up and down and the connecting structure 20 moves up and down accordingly.

During the upward movement of the carrier 13, the clockwise spur gear 33 meshes with the clockwise rack 35 and rotates with the rise of the carrier 13, and the clockwise spur gear 33 rotates to drive the coaxially arranged clockwise bevel gear 32 to rotate, Then, the bevel gear 34 meshing with the clockwise bevel gear 32 is rotated to communicate with the connecting structure 20 to rotate the camera. That is to say, the arrangement of the clockwise bevel gear 32 and the clockwise rack 35 converts the lifting torque of the stage 13 into a rotational torque that drives the bevel gear 34 and the connecting structure 20 to rotate.

During the operation, the driver 14 is connected to the screw 11 and drives the screw 11 to rotate in the forward direction, the stage 13 is lifted upward by a certain distance to make the camera extend, and then the forward-rotating spur gear 33 abuts the forward-rotating rack 35, and continues with the screw 11. Rotation, the carrier 13 continues to rise to engage with the clockwise rack 35 and rotate under the engagement of the clockwise rack 35, thereby driving the connecting structure 20 and the camera to rotate counterclockwise.

It can be seen from the above process that when the clockwise spur gear 33 meshes with the clockwise rack 35, the spring 23 is in a compressed state, and when the reverse spur gear 37 and the reverse rotation rack 39 mesh, the spring 23 is also in a compressed state. In this design, the clockwise spur gear 33 is subjected to the upward driving force of the carrier 13 , the downward resistance of the spring 23 and the torque of the clockwise rack 35 . The reverse spur gear 37 is simultaneously subjected to the upward driving force of the stage 13 , the downward resistance of the spring 23 and the torque of the reverse rotation rack 39 . The increase of the downward resistance of the spring 23 can alleviate the driving force of the upward movement of the stage 13 to make the movement more relaxed, so as to facilitate the precise control of the rotation angle.
