[0040] One side of the top of the two sliders 44 is fixedly connected to a push rod 45, and the front ends of the two push rods 45 are fixedly connected to push blocks 46. The opposite side of the two moving blocks 31 is formed with a positioning plate 53. The positioning plate 53 is fixedly connected to a support shaft 48 on the side close to the moving block 31.

[0041] Specifically, when installing the electromechanical transmission assembly, it is necessary to install multiple transmission parts. Because each part is too large and heavy, the parts are placed on the top of the upper support plate 30 before installation. At this time, the upper support plate 30 and the upper bracket 29 are in the initial position, flush with the top of the shell 2, and the electric push rod 26 is started to drive the baffle 28 to move, so that the baffle 28 pushes the first swing rod 7 to deflect, and then the first swing rod 7 drives the second swing rod 8 to deflect synchronously during the deflection, so as to lift the lifting frame 9, so that the spring 27 supports the baffle 28, and then the first swing rod 7 is buffered. When the second swing rod 8 is rising When the lifting frame 9 and the upper bracket 29 are lifted, the first rear support rod 21 and the second rear support rod 22 support the lifting frame 9, and the third rear support rod 23 and the fourth rear support rod 24 support the upper bracket 29, so that the lifting frame 9 and the upper bracket 29 are lifted, and the lifting frame 9 and the upper bracket 29 are lifted.

When the threaded rod 34 rotates, the two threaded sleeves 33 are driven to move relative to each other, so that the two threaded sleeves 33 drive the two moving shells 32 and the moving block 31 to move when moving, and then the two moving blocks 31 are driven to move relative to each other when moving, so that the positioning plates 53 limit the parts of larger volume, thereby improving the stability of the parts. When the threaded rod 34 rotates, the limiting grooves on both sides of the threaded rod 34 limit the limiting plates 36, so that the threaded rod 34 drives the two limiting plates 36 and the rotating sleeve 35 to rotate, and the moving shell 32 drives the rotating sleeve 35 to slide on the outside of the threaded rod 34 when moving.

When the push rod 45 moves, it drives the push block 46 to push the inclined rod 50 to deflect. When the inclined rod 50 deflects, it drives the L-shaped rod 49 to deflect. When the L-shaped rod 49 deflects, it drives the clamping plate 52 to move, so that when the clamping plate 52 moves, it blocks the large connection to prevent parts from falling. When the large parts are moved to the installation position, they are loosened to facilitate installation and improve stability during installation.
