The bottom end of the fixing frame 101 is fixedly connected to the table frame 301 by bolts, and the bottom end of the limiting frame 201 is fixedly connected to the table frame 301 by bolts. By fixing with bolts, the structure can be disassembled and replaced.

[0026] The cutting structure 1 includes a fixing frame 101. A fixing hole is provided at the top of the fixing frame 101. A hydraulic rod 102 is fixedly welded inside the fixing hole of the fixing frame 101. A connecting frame 103 is fixedly connected to the bottom end of the hydraulic rod 102 by welding. The connecting frame 103 fixedly connects the motor 104 and the hydraulic rod 102, making the connection of the cutting structure more stable. The motor 104 is fixedly clamped inside the connecting frame 103. The motor 104 is connected to an external power supply. A saw blade 105 is fixedly connected to the output end of the motor 104.

[0027] The fixing structure 2 includes a limiting frame 201. A rectangular limiting groove is provided on the side of the limiting frame 201. A limiting hole 202 is provided at the top of the limiting frame 201. The rectangular limiting groove of the limiting frame 201 communicates with the upper limiting hole 202. A pull rod 203 is movably sleeved inside the limiting hole 202. The outer diameter of the pull rod 203 is the same as the inner diameter of the limiting hole 202. The pull rod 203 moves up and down in the limiting hole 202, improving the connection stability. A pressing plate 204 is fixedly connected to the bottom end of the pull rod 203. Both sides of the pressing plate 204 are sleeved inside the limiting frame 201. The pressing plate 204 moves inside the sliding groove of the limiting frame 201.

[0028] Embodiment 2

[0029] As Figure 5As shown in the figure, based on the same concept as the above embodiments, this embodiment also proposes that the support structure 3 includes a table frame 301. A leakage groove 302 is provided at the central axis of the table frame 301. The leakage groove 302 facilitates the dust to fall into the collection groove 304 for collection. A plurality of threaded fixing holes are provided at the top end of the table frame 301, which are convenient for fixing and disassembling the device. The bottom end of the table frame 301 is fixedly connected with an adapter frame 303. The upper end of the adapter frame 303 corresponds to the leakage groove 302. A sliding groove is provided inside the adapter frame 303. A collection groove 304 is movably sleeved inside the sliding groove of the adapter frame 303. A clamping hole is provided on the right side of the table frame 301. A fixing frame 305 is fixedly connected to the right side of the table frame 301. The fixing frame 305 corresponds to the clamping hole 30. The clamping column 307 is inserted into the clamping hole under the push of 206. A second spring 306 is fixedly connected inside the fixing frame 305. The second spring 306 is compressed and deformed, making the applied pressure more stable. The other end of the second spring 306 is fixedly connected with a clamping column 307. The diameter of the clamping column 307 is the same as the diameter of the clamping hole of the table frame 301, improving the accuracy of the clamping structure. The clamping column 307 is movably sleeved inside the clamping hole of the table frame 301. A guard plate 308 is movably sleeved on the upper end of the table frame 301. A clamping hole is provided on one side of the guard plate 308 close to the fixing frame 305. The clamping hole of the guard plate 308 is the same size as the clamping hole of the table frame 301. The area of the guard plate 308 from the top-down view is smaller than the area of the table frame 301 from the top-down view, so that the guard plate 308 is clamped on the upper end of the table frame 301, and the protection structure of the guard plate 308 is more stable.

[0030] The working principle of the present utility model: Before use, first check whether the device can work properly to ensure that the device can operate normally during use. During use, first pull out the collection groove 304 clamped by the adapter frame 303 at the bottom end of the table frame 301, continue to clean the internal debris, and then insert it back into the inside. The guard plate 308 is sleeved on the upper end of the table frame 301 from above. Pull the clamping column 307 to compress and deform the second spring 306 inside the fixing frame 305, and pull out the clamping column 307 from the clamping hole of the table frame 301. Place the guard plate 308 on the upper end of the table frame 301. Release the clamping column 307, and the clamping column 307 is inserted back into the clamping holes of the table frame 301 and the guard plate 308. Pull the pull rod 203 to move upward in the limit frame 201, making the first spring 205 compressed and deformed, and the pressing plate 204 moves upward. The material is placed at the bottom end of the pressing plate 204. Release the pull rod 203, and the first spring 205 pushes the pressing plate 204 to clamp and fix the material. The material is placed at the lower end of the pressing plate 204, which is convenient for fixing the material and making the cutting device more stable. The motor 104 is powered on to drive the saw blade 105 to rotate. The fixed frame 101 is fixed with a hydraulic rod 102. The hydraulic rod 102 pushes the saw blade 105 downward to cut under the action of hydraulic pressure. Among them, the dust generated by the saw blade 105 cutting the material falls on the tabletop, and part of the dust falls into the collection groove 304 clamped by the adapter frame 303, and the collection groove 304 is pulled out for cleaning.
