In addition, it is a mature existing technology, which is conducive to the disassembly and assembly work.

[0036] Specifically, guide plates 961 are fixedly installed on the rear side of the movable plate 96, and guide rods 962 are slidably installed through the middle of the upper part of the guide plates 961. The left and right ends of the guide rods 962 are fixedly installed on adjacent fixed seats 3, which guide and limit the movement of the movable plate 96 so that it can slide smoothly left and right.

[0037] Specifically, a T-bolt 931 is threaded through the turntable 93 near the front side, which helps to limit the turntable 93 and prevent it from rotating due to accidental contact.

[0038] Specifically, a number of slots 911 are provided on the right side of the protective groove 91 near the bottom, and the slots 911 are arranged in a circular array with the center of the transmission rod 92 as the axis. The output end of the T-bolt 931 is inserted into the inner cavity of one of the slots 911, which facilitates the snapping of the turntable 93 after it stops rotating, and the snapping range is wide.

[0039] In this embodiment: when the fixed seat 3 is inserted into the inner cavity of the positioning groove, the turntable 93 can be rotated. When the turntable 93 rotates, it will drive the transmission rod 92 to rotate. When the transmission rod 92 rotates, it will drive the transmission shaft 95 to rotate through the chain 94. When the transmission shaft 95 rotates, it will drive the threaded rod 99 on the right side to rotate. Then, under the rotation of the shaft, it will drive the threaded rods 99 on both sides to rotate synchronously. When the threaded rod 99 rotates, it will drive the adjacent threaded sleeve 98 to move relative to each other. When the threaded sleeve 98 moves relative to each other, it will drive the adjacent moving plate 96 to move relative to each other. When the moving plate 96 moves relative to each other, it will drive the strip-shaped locking blocks 97 on both sides to move relative to each other, so that they are respectively inserted into the inner cavity of the adjacent locking interface to realize the installation between the fixed shell 4 and the fixed plate 1. After the installation is completed, the turntable 93 can be stopped from rotating. Then, the T-bolt 931 can be rotated to insert it into the inner cavity of a slot 911 to avoid accidental collision.

[0040] Working Principle: During use, the mounting plate 1 can be fixedly installed on the top plate through the mounting holes. After fixing, the mounting shell 4 can be placed below the mounting plate 1, and the mounting base 3 can be inserted into the inner cavity of the positioning groove. After insertion, it can be installed. After completion, the operator can adjust the height of the fresh food lamp body 7 according to the actual usage needs. By turning the knob 84, the movable rod 83 can be rotated. When the movable rod 83 rotates, it will cause the pawl 82 to deflect upward, thus moving away from the ratchet 81. At the same time, it will cause the spiral spring 831 to coil, thus releasing the restraint on the ratchet 81. Then, the servo motor 53 can be started. When the servo motor 53 runs, it will drive the drive gear 52 to rotate. When the drive gear 52 rotates, it will drive the rotating rod 5 to rotate through the driven gear 51. When the rotating rod 5 rotates, it will drive the connecting rope 6 to unwind, thus realizing the adjustment of the height of the fresh food lamp body 7. After the adjustment is completed, the servo motor 53 can be stopped. Then, the knob 84 can be released, so that the movable rod 83 is in the spiral spring 831. The spring returns to its original shape under the action of elasticity, thus continuing to engage with the ratchet 81. This prevents the connecting rope 6 from falling downwards under the weight of the fresh food lamp body 7 in the event of damage to the servo motor 53, improving safety during use. When the fixing seat 3 is inserted into the inner cavity of the positioning groove, the turntable 93 can be rotated. When the turntable 93 rotates, it drives the transmission rod 92 to rotate. When the transmission rod 92 rotates, it drives the transmission shaft 95 to rotate via the chain 94. When the transmission shaft 95 rotates, it drives the threaded rod 99 on the right side to rotate. Then, the rotation of the shaft drives the threaded rods 99 on both sides. When the threaded rod 99 rotates synchronously, it will cause the adjacent threaded sleeve 98 to move relative to each other. When the threaded sleeve 98 moves relative to each other, it will cause the adjacent moving plate 96 to move relative to each other. When the moving plate 96 moves relative to each other, it will cause the strip-shaped locking blocks 97 on both sides to move relative to each other, so that they can be inserted into the inner cavity of the adjacent locking interface respectively, realizing the installation between the fixed shell 4 and the fixed plate 1. After the installation is completed, the rotation of the turntable 93 can be stopped, and then the T-bolt 931 can be rotated to insert it into the inner cavity of a slot 911 to avoid accidental collision.
