[0024] The movable assembly 5 and the operating assembly 6 are arranged on the base 41. The movable assembly 5 comprises a sliding block 51 and a lead screw 52. The sliding block 51 is fixedly arranged on the bottom surface of the arc-shaped plate 42 and is in sliding connection with the base 41. The lead screw 52 is rotatably arranged on the base 41 and is in threaded connection with the sliding block 51. The movable assembly 5 further comprises a main bevel gear 53, a secondary bevel gear 54, a main gear shaft 55, a secondary gear shaft 56 and a transmission worm gear 57. The main gear shaft 55 is rotatably arranged in the base 41 and is fixedly connected with the main bevel gear 53 and the transmission worm gear 57 at both ends thereof. The secondary gear shaft 56 is also rotatably arranged in the base 41 and is fixedly connected with the secondary bevel gear 54 and the lead screw 52 at both ends thereof. The main bevel gear 53 is in meshing transmission connection with the secondary bevel gear 54. There are four arc-shaped plates 42, and the number of the secondary bevel gears 54 is consistent with the number of the arc-shaped plates 42, so that the positions of the four arc-shaped plates 42 can be adjusted at the same time, thereby ensuring that the whole structure is easy to operate, the whole operation process is time-saving, and the whole structure is suitable for actual use. The four secondary bevel gears 54 are symmetrically arranged around the main bevel gear 53 and are in meshing transmission connection with the main bevel gear 53.

[0025] The operating assembly 6 comprises a movable head 61, a connecting shaft 62, a friction block 63 and a driving worm 64. The movable head 61 is fixedly arranged on the end surface of the connecting shaft 62. The connecting shaft 62 is movably arranged in the base 41. The friction block 63 is fixedly arranged on the end surface of the connecting shaft 62 away from the movable head 61. The driving worm 64 is rotatably arranged in the base 41 and is in meshing transmission connection with the transmission worm gear 57. The operating assembly 6 further comprises a return spring 65 and a sliding rod 66. The two ends of the return spring 65 are fixedly connected with the friction block 63 and the driving worm 64, respectively. The sliding rod 66 is fixedly arranged on the friction block 63 and is in sliding connection with the driving worm 64. A hexagonal socket for cooperating with a hexagonal spanner is arranged on the movable head 61. A friction pattern for enhancing the friction between the friction block 63 and the base 41 is arranged on the side surface of the friction block 63. The friction generated by the friction pattern and the return spring 65 cooperate with each other, thereby limiting the movement of the friction block 63, so as to avoid the sliding of the arc-shaped plate 42 affecting the limiting effect of the glass tube during the transmission process, and further ensure that the whole transmission process is stable, so as to facilitate the processing and production of automobile lamp tubes.

[0026] The working principle is that the limiting member 4 is arranged on the plate-shaped structure in the conveying chain 2. The conveying chain 2 realizes reciprocating motion by means of the driving sprocket 3 on the support seat 1. The limiting space can be formed between the arc-shaped plates 42 in the limiting member 4. The glass tube of the lamp is inserted into the limiting space. The driving sprocket 3 is started, so as to drive the limiting member 4 and the glass tube on the limiting member 4 to be transmitted, thereby connecting the various processing equipment in the automobile lamp production line, so as to complete the processing of the automobile lamp.

[0027] The distance between the arc-shaped plates 42 needs to be adjusted to adapt to different thicknesses of the glass tube. When the hexagonal wrench is inserted into the movable head 61, the movable head 61 is pushed towards the inside of the base 41, and the friction block 63 fixedly connected with the movable head 61 is synchronously slid through the connecting shaft 62. At this time, the connecting shaft 62 and the friction block 63 are driven to rotate by the movable head 61, and the slide rod 66 fixed on the friction block 63 is in sliding connection with the driving worm 64. Therefore, the driving worm 64 rotates with the movable head 61, and because the driving worm 64 is in meshing transmission connection with the transmission worm 57, the transmission worm 57 is fixedly connected with the main gear shaft 55 and the main conical gear 53, and the auxiliary conical gear 54 in meshing transmission connection with the main conical gear 53 is fixedly connected with the auxiliary gear shaft 56 and the lead screw 52. Therefore, after the movable head 61 drives the driving worm 64 to rotate, the transmission worm 57 drives the main conical gear 53 to synchronously rotate, and then the auxiliary conical gear 54 drives the lead screw 52 to rotate. The arc-shaped plate 42 is further fixed with the sliding block 51 in sliding connection with the base 41, and the sliding block 51 is in sliding connection with the lead screw 52. Therefore, the sliding block 51 drives the arc-shaped plate 42 to slide on the base 41 with the rotation of the lead screw 52. The auxiliary conical gear 54 and the lead screw 52 are designed in multiple groups, so that all the arc-shaped plates 42 on the base 41 synchronously slide, thereby changing the size of the limiting space formed between the multiple arc-shaped plates 42 to adapt to the use of different thicknesses of the glass tube.

[0028] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
