[0021] Compared with the prior art, the advantages and positive effects of the present invention are:

[0022] In the present invention, two clamping plates are provided. Under the action of the threaded rod, the threaded barrel drives the threaded rod to extend and retract on the inner wall of the threaded barrel. During the extension and retraction process, the threaded rod drives the clamping plates to move on the top of the storage plate until the two clamping plates completely clamp the material. This effectively limits the position of the material and helps prevent materials with special shapes from being easily displaced on the top of the storage plate, thereby causing inconvenience in quick weighing.

The middle of the two clamping plates 61 away from each other are fixedly connected to a threaded rod 62, and the outer surface of the threaded rod 62 is threadedly connected to a threaded cylinder 63, and the outer surface of the threaded cylinder 63 is threaded. The surface is provided with side panels 64, and the two side panels 64 are symmetrically arranged on the top of the storage plate 2. A convenient disassembly device 7 is provided between the two side panels 64 and the storage plate 2. By setting two clamping plates 61, under the action of the threaded rod 62, the threaded cylinder 63 is rotated, and the threaded cylinder 63 will drive the threaded rod 62 to retract and contract on the inner wall of the threaded cylinder 63. During the retraction process, the threaded rod 62 will drive the clamping plate 61 to move on the top of the storage plate 2 until the two clamping plates 61 completely clamp the material, which can effectively limit the material, and is conducive to preventing materials with special shapes from easily shifting and connecting on the top of the storage plate 2, thereby causing inconvenience in quick weighing.

[0029] Reference Figure 2-Figure 4 As shown, the outer surface of the threaded barrel 63 is fixedly connected to a bearing 65, and the outer surface of the bearing 65 is fixedly connected to the inner wall of the side plate 64. By providing the bearing 65, the friction between the threaded barrel 63 and the side plate 64 can be reduced when the threaded barrel 63 rotates, thereby making the threaded barrel 63 more labor-saving when rotating; one end of the threaded barrel 63 is fixedly connected to an operating block 66, and the outer surface of the operating block 66 is provided with a protrusion. By providing the operating block 66, rotating the operating block 66 can drive the threaded barrel 63 to rotate.
