[0030] Embodiment Two

[0031] Please refer to Figures 1 - 5, based on the above embodiments, the fixing structure 3 of this embodiment includes a fixing frame 301 bolted to the output end of the driving motor 1. The fixing frame 301 is in the shape of a hollow cylinder. A docking frame 302 welded to the central position inside the fixing frame 301. The docking frame 302 is in the shape of a hollow cuboid with docking holes opened on all four sides. A spring 306 is arranged inside the fixing frame 301. The spring 306 is in a slightly compressed state. A sliding plate 303 is slidably connected to the fixing frame 301. A sliding groove is opened on the outer wall of the fixing frame 301. Both sides of the sliding protrusion of the sliding plate 303 are attached to the inner wall of the sliding groove. The sliding plate 303 is slidably connected to the docking frame 302. A square hole is opened at the central position of the sliding plate 303. The docking frame 302 passes through the square hole of the sliding plate 303 to ensure the stability of the sliding plate 303 during movement. A fixing block 305 is slidably connected to the docking frame 302. The fixing block 305 passes through the square hole of the docking frame 302 and fits with the drill bit 4. The fixing block 305 is embedded in the docking groove at one end of the drill bit 4. The inner wall of the docking groove of the drill bit 4 fits with the outer wall of the fixing block 305 to ensure the stability of the drill bit 4 after fixation. One end of the spring 306 is attached to one side of the sliding plate 303, and the other end of the spring 306 is attached to the inner wall of the fixing frame 301. Through the spring 306, the sliding plate 303 can quickly return to the initial position, improving the installation efficiency of the drill bit 4. The movement of the sliding plate 303 can drive the movement of the fixing block 305 to fix the drill bit 4. A sliding rod 307 is welded to the inner wall of the fixing frame 301, and the sliding rod 307 is slidably connected to the fixing block 305. Through the sliding rod 307, the fixing block 305 can be limited to ensure the stability of the fixing block 305 during movement. A guide rod 308 is slidably connected to the sliding plate 303, and the guide rod 308 is welded to the inner wall of the fixing frame 301, and the guide rod 308 passes through the hole in the center of the spring 306. Through the guide rod 308, the spring 306 is limited to prevent the spring 306 from being displaced during deformation.

[0032] Embodiment III

[0033] Please refer to Figures 1 - 5 , based on the above embodiments, the limiting structure 5 of this embodiment is arranged on the outer wall of the fixing frame 301. The limiting structure 5 includes a limiting frame 501 welded to the outer wall of the fixing frame 301. The limiting frame 501 is made of stainless steel to prevent the limiting frame 501 from rusting due to the influence of external moisture. A limiting plate 502 rotatably connected to one side of the limiting frame 501. Through the limiting plate 502, the sliding plate 303 can be limited and fixed to prevent the sliding plate 303 from shaking due to external influence. A total of four groups of limiting plates 502 are provided, and rubber pads are arranged on one side of the four groups of limiting plates 502. By providing rubber pads, the rubber pads will increase the friction between the sliding plate 303 and the limiting plate 502, and can better fix the sliding plate 303 to ensure the stability of the sliding plate 303 after fixation.

[0034] Working principle: First, when it is necessary to replace the damaged drill bit 4, rotate the limit plate 502 by 90° to separate the rubber pad on one side from the sliding plate 303, release the fixation of the sliding plate 303, and then push the sliding plate 303. Since the sliding plate 303 is rotatably connected to the connecting rod 304, the connecting rod 304 is rotatably connected to the fixed block 305, and the fixed block 305 is slidably connected to the sliding rod 307, the movement of the sliding plate 303 will drive the fixed block 305 to move. The movement of the fixed block 305 separates from the docking groove of the drill bit 4, releases the fixation of the drill bit 4, and pulls the drill bit 4 to separate it from the docking frame 302, completing the disassembly of the drill bit 4;

[0035] Second, when it is necessary to install a new drill bit 4, push the sliding plate 303 again. The movement of the sliding plate 303 will drive the fixed block 305 to move to one side of the docking frame 302. And the horizontal movement of the sliding plate 303 causes the spring 306 to deform. Insert the square end of the drill bit 4 into the docking frame 302, release the sliding plate 303, and the spring 306 will restore its deformation and push the sliding plate 303 to move. The movement of the sliding plate 303 drives the fixed block 305 to move, and the fixed block 305 moves and is embedded in the docking groove of the drill bit 4. Then rotate the limit plate 502 reversely by 90° so that the rubber pad on one side fits against one side of the sliding plate 303, and limit and fix the sliding plate 303 through the limit plate 502 to ensure the stability of the drill bit 4 after fixation. The operation is simple and convenient for the staff to replace the damaged drill bit 4.
