[0025] Embodiment 1

[0026] As Figure 1 、 Figure 2 、 Figure 4As shown in the figure, this device includes a first frame 1 and a second frame 2. A driving component 3 is arranged inside the first frame 1, and an adjusting component 4 is arranged inside the second frame 2. The driving component 3 includes a rotating rod 301 connected to the lower end inside the first frame 1. A connecting rod 302 is connected to the upper end inside the first frame 1. Moreover, a driven gear 303 fixedly sleeved on the left side of the outside of the connecting rod 302 is in tooth engagement with a driving gear 304 fixedly sleeved on the left side of the outside of the rotating rod 301. A handle 305 is slidably connected to the right side inside the rotating rod 301. The adjusting component 4 includes guiding grooves 401 integrally arranged on the left and right sides inside the second frame 2. The upper and lower ends of the guiding grooves 401 are connected and slidably provided with sliding columns 402. A pushing plate 403 is rotatably sleeved on the outside of the sliding columns 402. The other end of the upper pushing plate 403 is fixedly sleeved on the outside of the connecting rod 302, and the other end of the lower pushing plate 403 is fixedly sleeved on the outside of the rotating rod 301.

[0027] Installation plates 5 are longitudinally arrayed and fixedly arranged inside the first frame 1 from top to bottom. Connection plates 6 are longitudinally arrayed and fixedly arranged inside the second frame 2 from top to bottom. The number of connection plates 6 is the same as the number of installation plates 5, and the connection plates 6 and the installation plates 5 correspond to each other one by one. The connection plates 6 slide through the installation plates 5.

[0028] The worker rotates the handle 305, causing the handle 305 to drive the rotating rod 301 to rotate. The rotating rod 301 drives the driving gear 304 to drive the driven gear 303 and the connecting rod 302 to rotate synchronously and in different directions. At this time, the rotating rod 301 drives the lower pushing plate 403 and the lower sliding column 402 to move along the direction of the guiding groove 401. At the same time, the connecting rod 302 drives the upper pushing plate 403 and the upper sliding column 402 to move along the direction of the guiding groove 401. That is, the sliding columns 402 at the upper and lower ends inside the guiding groove 401 are in a state of moving away from or towards each other. Through the above method, the pushing plate 403 drives the sliding column 402 to push the guiding groove 401 and the second frame 2 to move in the direction of or in the opposite direction of the first frame 1. Synchronously, the second frame 2 drives the connection plate 6 to move in the direction of the installation plate 5, thereby realizing the adjustment of the distance between the first frame 1 and the second frame 2. After the adjustment is completed, the worker can then place the goods on the connection plate 6 and the installation plate 5.

[0029] Embodiment 2

[0030] As Figure 3 、 Figure 5As shown, a guide hole 7 is integrally provided on the right side inside the rotating rod 301. The cross-section inside the guide hole 7 and the outer cross-section of the handle 305 are both square-designed. A spring 8 is fixedly provided on the left side of the handle 305, and the other end of the spring 8 is fixedly connected to the rotating rod 301. The spring 8 is a compression spring. Rollers 9 are fixedly provided on the left and right sides at the bottom of the second frame 2. The bottom surface of the rollers 9 is designed to be in the same plane as the bottom surface of the first frame 1. An L-shaped plate 10 is fixedly provided in the middle of the right side of the outer wall of the first frame 1, and the L-shaped plate 10 is sleeved outside the rotating rod 301. A number of jacks 11 are integrally provided around the inside of the L-shaped plate 10. The center of the circular ring formed by the surrounding of the jacks 11 is concentric with the center of the rotating rod 301. A positioning rod 12 is fixedly provided on the outer wall of the handle 305, and the positioning rod 12 can be detachably inserted into any one of the jacks 11.

[0031] According to the operation method in Embodiment 1, when the staff rotates the handle 305, they need to first pull the handle 305 to make the handle 305 move along the right side direction of the guide hole 7, so that the handle 305 drives the positioning rod 12 to disengage from the jack 11, and the spring 8 deforms. When the distance between the first frame 1 and the second frame 2 is adjusted, then release the handle 305 by hand. Through the resilience of the spring 8, the handle 305 drives the positioning rod 12 to insert into the currently corresponding jack 11, so as to lock the state after the distance between the first frame 1 and the second frame 2 is adjusted. In addition, through the rolling friction of the rollers 9 on the ground, the smoothness of the displacement of the second frame 2 is ensured. Through the square design of the outside of the handle 305 and the inside of the guide hole 7, the stability of the synchronous rotation of the handle 305 driving the rotating rod 301 is ensured.
