the fixing device comprises a handle 205, the handle 205 penetrates through the workbench 101, the handle 205 is rotatably connected with the workbench 101, the other end of the handle 205 is fixedly connected with a first threaded shaft 206, the left end face of the first threaded shaft 206 is fixedly connected with a connecting shaft 207, the left end face of the connecting shaft 207 is fixedly connected with a second threaded shaft 208, the second threaded shaft 208 is rotatably connected with the workbench 101, the outer sides of the first threaded shaft 206 and the second threaded shaft 208 are both spirally connected with a second sliding block 209, the second sliding block 209 penetrates through the workbench 101, the second sliding block 209 is slidably connected with the workbench 101, the top end face of the second sliding block 209 is fixedly connected with a second limiting plate 210, the second limiting plate 210 is slidably connected with the workbench 101, and the furniture plate can be fixed by the arrangement; the thread direction of the first threaded shaft 206 is opposite to that of the second threaded shaft 208, and the first threaded shaft 206 and the second threaded shaft 208 are symmetrically distributed on the right side and the left side of the connecting shaft 207, so that the moving directions of the two second sliders 209 can be opposite.

The working process is as follows: the power of all electrical apparatus in the device is external power supply, add man-hour, put the furniture board between two second limiting plates 210, it rotates to drive first threaded shaft 206 through rotating handle 205, first threaded shaft 206 drives second threaded shaft 208 through connecting axle 207 and rotates, first threaded shaft 206 and second threaded shaft 208 drive second slider 209 respectively and slide, second slider 209 drives second limiting plate 210 motion and presss from both sides tight furniture board, carry out spacing fixed to the furniture board, thereby can fix the furniture board during the use, it is more convenient to polish and polish the furniture board.

The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts of the present invention. The foregoing is only a preferred embodiment of the present invention, and it should be noted that there are objectively infinite specific structures due to the limited character expressions, and it will be apparent to those skilled in the art that a plurality of modifications, decorations or changes may be made without departing from the principle of the present invention, and the technical features described above may be combined in a suitable manner; such modifications, variations, combinations, or adaptations of the invention using its spirit and scope, as defined by the claims, may be directed to other uses and embodiments.
