[0018] Furthermore, a plurality of movable shafts are provided inside the frame, and rollers are sleeved on the outer walls of the movable shafts and the outer walls of the driving shafts.

[0019] By adopting the above technical solution, if the movable shaft and the driving shaft rotate at the same time, they will drive the roller to rotate, and the roller can transport the objects.

[0020] Furthermore, the outer wall of the movable shaft and the outer wall of the driving shaft are sleeved with first sprockets, and a first chain is meshed and connected between every two first sprockets.

[0021] By adopting the above technical solution, when the driving shaft rotates, it will drive the first sprocket to rotate, then drive the first chain to rotate, and then drive the other first sprocket to rotate.

[0022] Furthermore, a top end of the connecting shaft is connected to a rotating disk, and the sliding seat is slidably connected to the sliding rod.

[0023] By adopting the above technical solution, it is convenient for the user to rotate the connecting shaft connected to the turntable through the turntable, and at the same time the slide rod can guide the slide seat so that the slide seat slides on the slide rod.

[0024] Furthermore, the rotating plate is rotatably connected to the pressing plate via a rotating shaft.

[0025] By adopting the above technical solution, the rotating plate can be rotated through the rotating shaft, and the rotating plate can push the sliding seat to move when rotating.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] The utility model is provided with an adjustment component. When the spacing between the two side plates needs to be adjusted to meet the requirement of limiting the position of objects of different sizes, the user can rotate the turntable, and the turntable drives the connecting shaft connected thereto to rotate. When the connecting shaft rotates, it drives the second sprocket connected thereto to rotate, and drives another second sprocket to rotate through the second chain, so that the two connecting shafts rotate at the same time, and when the connecting shaft rotates, it drives the threaded hole to rotate. Since the threaded column is restricted from rotating, the threaded column can only move. When the threaded column moves, it drives the pressure plate to move, and then drives the rotating plate to rotate. The rotating plate pushes the slide seat to move, and drives the side plate to move. In this way, the spacing between the two side plates can be quickly adjusted to meet the requirement of limiting the position of objects of different sizes. At the same time, the guide wheels on the side plates will only contact the objects, and will not exert a large extrusion force on the objects, so that the objects can move smoothly on the roller. At the same time, the spacing between the side plates can be quickly adjusted in this way, and there is no need to rotate multiple screws to adjust the position of the side plates. The adjustment process is simple and convenient, thereby improving the efficiency of adjusting the position of the side plates. BRIEF DESCRIPTION OF THE DRAWINGS
