[0046] Furthermore, the lampshade adjustment member also includes a driving rod 46 rotatably arranged in the sliding rod 12, the driving rod 46 is fixedly connected to a second winding wheel 47 outside, the second winding wheel 47 is wrapped with a second connecting rope 49 outside, the second connecting rope 49 passes through the sliding rod 12 and is fixedly connected to the fixed plate 1, the driving rod 46 is fixedly connected to a fan gear 48 meshing with the first gear 45 outside, the fan gear 48 is arranged in an incomplete type, when the fan gear 48 drives the first gear 45 to rotate, the rotation speed of the first gear 45 is reduced, thereby adjusting the movement rate of the first connecting rope 41, and adjusting the efficiency of the opening adjustment of the lampshade assembly 2.

[0047] Specifically, a coil spring 491 is provided on the outer sleeve of the driving rod 46, and the two ends of the coil spring 491 are respectively fixedly connected to the second winding wheel 47 and the sliding rod 12. A guide wheel 42 is rotatably provided at the bottom of the connecting plate 21. The guide wheel 42 is in rolling contact with the first connecting rope 41, and the first connecting rope 41 is guided by the guide wheel 42 to ensure the rotation direction of the rotating plate 22. The coil spring 491 limits the second winding wheel 47, so that after the second connecting rope 49 is stretched, the second winding wheel 47 rotates, thereby stretching the coil spring 491. When the sliding rod 12 moves up, the second winding wheel 47 is driven to rotate by the coil spring 491, thereby winding the second connecting rope 49.

[0048] In the embodiment provided by the present invention, a locking member is also included. When the sliding rod 12 stops sliding in the rotating tube 11, the lamp cover assembly 2 is locked by the locking member to lock the opening of the lamp cover assembly 2. The locking member includes a guide plate 51 fixed to the outside of the sliding rod 12, and an L-shaped rod 52 is slidably arranged in the guide plate 51. The L-shaped rod 52 extends into the sliding rod 12. A limiting hole 56 is provided in the movable rod 37. The L-shaped rod 52 is slidably arranged in the limiting hole 56. The bottom end of the L-shaped rod 52 is fixedly connected to a locking plate 53.

[0049] In the solution further provided by the present invention, the locking member also includes a connecting block 54 fixed to the outside of the L-shaped rod 52, and a return spring 55 is provided on the outer sleeve of the L-shaped rod 52, and the two ends of the return spring 55 are respectively fixedly connected to the guide plate 51 and the connecting block 54, and the return spring 55 generates a pulling force on the connecting block 54, pulling the connecting block 54 to generate a downward force, so that the L-shaped rod 52 drives the locking plate 53 to stably lock the first gear 45, and the elastic force of the return spring 55 is greater than the elastic force of the elastic rubber 23.

[0050] In the present invention, the height of the guide hole 39 is greater than the height of the limiting hole 56, and the height difference between the guide hole 39 and the limiting hole 56 is the height of the locking plate 53. When the wedge plate moves in the guide hole 39, it pushes the moving rod 37 to move upward, thereby causing the limiting hole 56 to move upward. When the bottom of the limiting hole 56 contacts the L-shaped rod 52, the wedge plate drives the moving rod 37 to continue to move upward, thereby causing the moving rod 37 to drive the L-shaped rod 52 to move upward, thereby unlocking the first gear 45.

[0051] When the lampshade assembly 2 is used, when the user needs to use it to find something, the user holds the sliding rod 12, and then presses the wedge-shaped rod 38 to move into the guide hole 39 in the sliding rod 12, thereby pushing the moving rod 37 to move upward, so that the spiral groove 371 moves upward, and the fixing block 35 rotates in the spiral groove 371, thereby driving the rotating rod 34 to rotate synchronously, so that the pull cord 36 is reeled in, so that the clamping rod 31 moves into the sliding rod 12, and the clamping spring 32 is compressed;

[0052] When the clamping rod 31 moves out of the clamping plate 33, the sliding rod 12 is unlocked from the rotating tube 11, so that the sliding rod 12 slides in the rotating tube 11 by pulling the sliding rod 12. When it moves to a suitable position, the wedge rod 38 is released, and the clamping spring 32 is elastically released, so that the clamping rod 31 is pushed to move into the clamping plate 33, and the sliding rod 12 is clamped and limited. At the same time, the rotating rod 34 rotates to make the moving rod 37 move downward, so that the wedge plate is moved out of the sliding rod 12.

[0053] When the wedge plate moves and pushes the moving rod 37 to move upward, the limiting hole 56 is driven to move upward. When the bottom of the limiting hole 56 contacts the L-shaped rod 52, the wedge plate drives the moving rod 37 to continue to move upward, so that the moving rod 37 drives the L-shaped rod 52 to move upward, so that the return spring 55 is compressed. At the same time, the L-shaped rod 52 moves and drives the locking plate 53 to move upward, thereby unlocking the first gear 45.

[0054] When the sliding rod 12 moves downward, the second winding wheel 47 moves downward synchronously. Under the pulling of the second connecting rope 49, the second winding wheel 47 rotates, thereby twisting the coil spring 491. At the same time, the second winding wheel 47 drives the driving rod 46 to rotate, so that the fan gear 48 rotates, driving the first gear 45 to rotate synchronously. The rotation of the first gear 45 drives the connecting rod 43 to rotate synchronously, thereby rotating the first winding wheel 44, thereby winding the first connecting rope 41, thereby rotating the rotating plate 22, driving the elastic rubber 23 to compress, thereby reducing the opening of the lampshade assembly 2, making the light more concentrated, thereby making the light brighter;

[0055] When the wedge block moves outward, the moving rod 37 drives the limiting hole 56 to move downward, thereby pushing the L-shaped rod 52 downward through the return spring 55, so that the locking plate 53 locks the first gear 45.

[0056] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
