[0025] The effect achieved by the entire embodiment 1 is that when adjusting the position of the guide rail 13, the staff pulls the pull plate 12, the pull plate 12 drives the block 10 to leave the slot 6, the spring 9 is compressed, and the block 10 enters the limit slot 8, and then the staff pulls the guide rail 13, the guide rail 13 drives the slide plate 7 to move until the guide rail 13 moves to the desired position, at this time the staff releases the pull plate 12, the block 10 enters the slot 6 under the elastic force of the spring 9, and fixes the slide plate 7 and the guide rail 13, so that the position of the guide rail 13 can be changed according to the size of the object, thereby improving the transportation efficiency of the staff.

[0026] Embodiment 2, as Figure 1-Figure 5 As shown, further, a storage plate 4 is slidably installed on one side opposite to the two guide rails 13, and two blocks 20 are symmetrically installed on one side of the storage plate 4. The two blocks 20 are slidably connected to the two guide rails 13 respectively, and multiple evenly distributed rollers 21 are arranged on both sides of the two storage plates 4 to reduce friction and facilitate the sliding of the storage plates 4.

[0027] Furthermore, a first L-shaped plate 14 is fixedly installed on the top and bottom of the two guide rails 13, a threaded rod 15 is rotatably installed between the two first L-shaped plates 14, the top of the threaded rod 15 passes through the first L-shaped plate 14 and is fixedly installed with a rotating shaft 16, and the outer wall of the threaded rod 15 is threadedly connected to two second L-shaped plates 17.

[0028] Furthermore, a limiting rod 19 is fixedly installed between the two first L-shaped plates 14 , and the limiting rod 19 passes through the two second L-shaped plates 17 and is slidably connected to the two second L-shaped plates 17 .

[0029] Furthermore, two limit plates 18 are symmetrically mounted on one end of the two guide rails 13 close to the threaded rod 15 .

[0030] Furthermore, a wall 1 is provided on one side of the main body 2.

[0031] Furthermore, the threaded rod 15 is provided with two sections of threads with opposite textures, and the threaded rod 15 is connected to the two second L-shaped plates 17 respectively through the two sections of threads with opposite textures.

[0032] The effect achieved by the entire embodiment 2 is that when replacing the storage plate 4, the staff rotates the rotating shaft 16, the threaded rod 15 rotates, and the two second L-shaped plates 17 move away from each other. The staff can then pull the block 20 out of the guide rail 13, making it convenient to replace the storage plate 4 when it is damaged.

[0033] Working principle: When adjusting the position of the guide rail 13, the staff pulls the pull plate 12, and the pull plate 12 drives the block 10 to leave the slot 6. The spring 9 is compressed, and the block 10 enters the limit slot 8. Then the staff pulls the guide rail 13, and the guide rail 13 drives the slide plate 7 to move until the guide rail 13 moves to the required position. At this time, the staff releases the pull plate 12, and the block 10 enters the slot 6 under the elastic force of the spring 9, fixing the slide plate 7 and the guide rail 13. In this way, the position of the guide rail 13 can be changed according to the size of the object, thereby improving the transportation efficiency of the staff. When using the storage plate 4, the staff rotates the shaft 16, the threaded rod 15 rotates, and then drives the two second L-shaped plates 17 to approach each other. When the two second L-shaped plates 17 are in contact with the two limit plates 18 respectively, the rotation of the shaft 16 is stopped. At this time, when the staff pulls the storage plate 4, the two second L-shaped plates 17 will prevent the block 20 from leaving the guide rail 13, so that the storage plate 4 will not work beyond the range. When replacing the storage plate 4, the staff rotates the shaft 16, the threaded rod 15 rotates, and drives the two second L-shaped plates 17 away from each other. The staff can pull the block 20 out of the guide rail 13, which is convenient for replacing the storage plate 4 when it is damaged.
