[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a civilian product that keeps food or other items in a constant low temperature and cold state. The freezer layer of the refrigerator requires a freezer drawer to store, collect and separate food to prevent food from odor contamination. During processing, the freezer drawer often needs a clamping device to clamp it to facilitate subsequent chamfering, burr removal and other processing. However, the existing processing clamping device is inconvenient to adjust in actual use. The drawer is difficult to adjust the angle freely when clamped, and the processing efficiency is low; the operation is complicated, and the drawer is inconvenient to take up and put down.

[0005] By adopting the above technical solution, the clamping mechanism drives the push-pull plate to move up and down by driving the hydraulic cylinder piston rod to extend and retract. Since the racks on both sides of the push-pull plate are meshed with the connecting piece gears, the connecting piece and the rack cooperate to drive the clamping plates to move closer to each other to clamp the drawer body for grinding burrs and other processing. When the drawer body needs to be rotated to process other surfaces, it is only necessary to rotate the rotating component. After the processing is completed, the push-pull plate is controlled to drive the two clamping plates away from each other to release the drawer body, and the next drawer body can be replaced for processing. It is convenient to take and place, and the direction of the drawer can be adjusted without taking it down. The operation is simple and the processing efficiency can be improved.

[0006] The utility model is further configured as follows: the rotating assembly includes an internal gear fixed on the clamping plate near the connecting rod three side, a pillar is provided on one side of the clamping mechanism, a rotating part is rotatably connected to one side of the pillar, the rotating part includes a cylindrical pin, the cylindrical pin extends into the interior of the internal gear to drive the internal gear to rotate, a rotating rod is rotatably connected to the pillar, a hand wheel is fixedly connected to one side of the rotating rod, and the other side is fixedly connected to the rotating part.

[0007] By adopting the above technical solution, when the clamping plate clamps the drawer body, the hand wheel is turned to drive the rotating rod on the pillar to rotate, thereby the rotating part rotates, and when the cylindrical pin rotates, it cooperates with the internal gear to drive the internal gear to rotate, thereby rotating the clamping plate fixed to the internal gear, and the clamping plate tightens the drawer body, thereby rotating the drawer body, making it convenient to process each surface of the drawer body and further improving the processing efficiency.

[0008] The utility model is further configured as follows: the first connecting rod and the second connecting rod are of equal length and are arranged in parallel.

[0009] By adopting the above technical solution, the connecting rod 1 drives the connecting rod 2 to translate synchronously through the connecting rod 3, so that the connecting rod 1 can be limited.

[0010] The utility model is further configured as follows: it also includes a square placement rack, the square placement rack is used to place the drawer body, a base is provided at the bottom of the U-shaped rack, a slide groove is opened on the base, the placement rack is slidably connected in the slide groove, and a handle is provided on one side of the placement rack.

[0011] By adopting the above technical solution, the handle is pulled to drive the placement rack to move in the slide groove on the base. Before clamping, the placement rack is pulled to the middle of the clamping plate, the drawer body is placed on the placement rack, and then the clamping assembly is started to fix it. After fixing, the handle is pulled to move the placement rack away from the clamping plate. This avoids the inconvenience of fixing the drawer body by hand and does not affect the rotation direction of the drawer body driven by the clamping plate. It is convenient and practical.

[0012] The utility model is further configured as follows: the U-shaped frame is provided with an L-shaped groove, the connecting piece is hinged in the L-shaped groove, the cross bar is provided with a through groove, and the second connecting rod is hinged in the through groove.

[0013] By adopting the above technical solution, the connecting piece is hinged in the L-shaped groove, and the second connecting rod is hinged in the through groove, which can make the rotation smoother and prevent jamming.

[0014] The utility model is further configured as follows: buffer pads are arranged on opposite sides of the two clamping plates.

[0015] By adopting the above technical solution, the buffer pad can prevent the problem of wear on the surface of the drawer body caused by the clamping plate being too tight when clamping.

[0016] The beneficial effects of the utility model are as follows: the push-pull plate is driven to move up and down by the extension and contraction of the hydraulic cylinder piston rod arranged on the U-shaped frame, and racks are arranged on both sides of the push-pull plate to mesh with the connecting gear, so that the connecting member and the rack cooperate to drive the clamping plates to approach each other to clamp the drawer body for grinding burrs and other processing work. After the processing is completed, the push-pull plate is controlled to drive the two clamping plates to move away from each other to release the drawer body, and the next drawer body can be replaced for processing, which is convenient for taking and placing and can improve the processing efficiency. By setting a rotating component to drive the clamping plate to rotate to realize the rotation of the drawer body, it is convenient to process other surfaces of the drawer body, and the direction of the drawer body can be adjusted without removing it. The operation is simple and can further improve the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
