A rotating component for rotating the support frame 501 is provided inside the operating table 300. By starting the first motor 502, it drives the bidirectional screw rod 503 to rotate, so that the two clamping blocks 504 are moved closer to or away from each other in the support frame 501.

[0033] like Figure 2 As shown, the rotating assembly includes a second motor 505, the second motor 505 is arranged inside the operating table 300, and a worm 506 is provided at the output end of the second motor 505. The worm 506 is meshed with a worm wheel 507, and a rotating column 508 is fixedly connected inside the worm wheel 507. The rotating column 508 is rotatably connected to the inside of the operating table 300, and the top of the rotating column 508 is fixedly connected to the bottom of the support frame 501. By starting the second motor 505, it drives the worm 506, thereby driving the worm wheel 507 and the rotating column 508.

[0034] like Figure 1 and Figure 2 As shown, both sides of the operating table 300 are provided with absorption components for absorbing dust, and the absorption components include a fixed frame 601, and the fixed frame 601 is fixedly connected to both sides of the operating table 300. A first slider 602 is slidably connected inside the fixed frame 601, and a third motor 603 is provided above the first slider 602. A first threaded rod is provided at the output end of the third motor 603. The bottom of the first threaded rod is rotatably connected to the top of the first slider 602, and a second slider 604 is threadedly connected to the outer surface of the first threaded rod. A limiting rod is also slidably connected inside the second slider 604, and the bottom of the limiting rod is fixedly connected to the top of the first slider 602, and a limiting plate is provided on the top of the limiting rod. A negative pressure dust suction device 605 is provided on the side of the second slider 604 away from the first threaded rod. By starting the third motor 603, it drives the first threaded rod to rotate, and then under the limit of the limiting rod, the second slider 604 can be raised and lowered, thereby driving the negative pressure dust suction device 605.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, a driving component for driving the first slider 602 is provided inside the fixed frame 601, and the driving component includes a fourth motor 606. The fourth motor 606 is provided on one side of the fixed frame 601, and a second threaded rod 607 is provided at the output end of the fourth motor 606. The second threaded rod 607 is rotatably connected to the fixed frame 601, and the second threaded rod 607 is threadedly connected to the first slider 602. By starting the fourth motor 606, the second threaded rod 607 is driven to rotate, and then the first slider 602 is moved inside the fixed frame 601 under the limit of the fixed frame 601.

[0036] like Figure 1 As shown, a cleaning component for cleaning wood chips is provided on the top of the base 100, and the cleaning component includes an electric push rod 701, and the electric push rod 701 is arranged around the top of the base 100. A push plate 702 is provided at the output end of the electric push rod 701. A discharge trough 703 is provided at a position of the base 100 and the collection box 400 near the operating table 300. By starting the electric push rod 701, it drives the push plate 702 to move.

[0037] like Figure 1 As shown, the plurality of push plates 702 are staggered with each other to prevent the push plates 702 from interfering with each other when moving.

[0038] like Figure 1 and Figure 2 As shown, the length of the support frame 501 and the first motor 502 is smaller than the distance between the two first sliders 602, so as to prevent the support frame 501 from interfering with each other when rotating.

[0039] like Figure 3 As shown, a limiting groove matching with the discharge groove 703 is provided at the bottom of the fixed frame 601 to prevent wood chips from being retained in the fixed frame 601 and making the first sliding block 602 unable to move.

[0040] Example 2

[0041] like Figure 1 and Figure 2 As shown, the difference from Example 1 is that the negative pressure vacuum device 605 does not contact the limiting plate to prevent the negative pressure vacuum device 605 from colliding when lifting or lowering.

[0042] The above embodiment discloses a wooden model polishing device, wherein the operator places the model to be polished on the top of the support frame 501, and then starts the first motor 502 to drive the bidirectional screw rod 503 to rotate, so that the two clamping blocks 504 are close to each other in the support frame 501, thereby clamping the model, and then the operator uses the handheld grinder 200 to polish. During the polishing, wood chips and dust will fly. At this time, the negative pressure vacuum device 605 can be raised and lowered according to the models of different sizes. The third motor 603 can be started to drive the first threaded rod to rotate, and then the second slider 604 can be raised and lowered under the limit of the limit rod, thereby driving the negative pressure vacuum device 605 to adapt to different heights, and then the negative pressure vacuum device 605 is used to adjust the height of the model. The device 605 absorbs dust in the air, and can also start the fourth motor 606 to drive the second threaded rod 607 to rotate, and then under the limit of the fixed frame 601, the first slider 602 drives the negative pressure dust suction device 605 to move inside the fixed frame 601, thereby changing the dust suction position, and some large wood chips will be scattered on the surface of the base 100. At this time, the electric push rod 701 can be started to drive the push plate 702 to move, so that the push plate 702 pushes the wood chips into the discharge trough 703, and then falls into the collection box 400. After one side is polished, the second motor 505 can be started to drive the worm 506, thereby driving the worm wheel 507 and the rotating column 508, thereby driving the model to rotate, so that it can be polished in many aspects.

[0043] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
