[0022] As a technical optimization scheme of the utility model, four sliding grooves 302 are formed on the mounting seat 301, two reinforcing rods 405 are fixedly connected to the two supporting blocks 401, the reinforcing rods 405 are slidably connected between the sliding grooves 302, an inclined groove 303 is formed on the bottom plate 1, the inclined groove 303 is located directly below the mounting seat 301, one storage box 304 is clamped to each side of the bottom plate 1, the storage box 304 is communicated with the inclined groove 303, the inclined groove 303 and the internal space of the mounting seat 301 are interconnected, and the two inclined grooves 303 are symmetrically arranged; meanwhile, when the cutting process causes the waste to fall between the two supporting blocks 401, the internal space of the mounting seat 301 and the two inclined grooves 303 at the bottom are interconnected, and then the waste falling into the mounting seat 301 slides into the storage box 304 on the two sides of the bottom plate 1 through the inclined groove 303, thereby avoiding the problem of blockage caused by the accumulation of waste and facilitating cleaning.

[0023] As a technical optimization scheme of the utility model, the clamping structure 2 comprises two mounting racks 201, the upper surface of the bottom plate 1 is fixedly connected with the two mounting racks 201, the cross section of the knob 404 is in a "convex" character structure, the cross section of the baffle 406 is in an "L" character structure, the top end of the two mounting racks 201 is slidably connected with two first guide rods 202, the four first guide rods 202 are fixedly connected with a connecting plate 203, the center position of the connecting plate 203 is provided with a clamping block 205, the upper surface of the clamping block 205 is fixedly connected with two adjusting rods 204, two nuts 206 are threadedly connected to the two adjusting rods 204, the four nuts 206 are in mutual abutment with the outer wall of the connecting plate 203, one of the mounting racks 201 is fixedly connected with a supporting rack 207, the supporting rack 207 is fixedly connected with a hydraulic rod 208, and the telescopic end of the hydraulic rod 208 is fixedly connected with the connecting plate 203; after the support of the bottom of the monocrystalline silicon rod is completed, the four nuts 206 are sequentially rotated, the position of the clamping block 205 is preliminarily adjusted according to the radius of the monocrystalline silicon rod, the extension distance of the hydraulic rod 208 is reduced, the operation efficiency is improved, then the hydraulic rod 208 on the supporting rack 207 drives the connecting plate 203 to move downward, the connecting plate 203 drives the first guide rod 202 to move downward along the inner wall of the mounting rack 201, then the connecting plate 203 drives the clamping block 205 at the center position to extrude the monocrystalline silicon rod downward, so that the monocrystalline silicon rod is quickly clamped and fixed, and the firmness is high.

[0024] In use, the fixture is first installed at a designated position on the cutting equipment via the base plate 1. Then, the monocrystalline silicon rod is moved directly above the mounting base 301 and horizontally lowered. Under the weight of the monocrystalline silicon rod, the two support blocks 401 move laterally along the inner wall of the mounting base 301. The support blocks 401 drive the second guide rod 402 to slide outward, simultaneously compressing the spring 403 between the support blocks 401 and the inner wall of the mounting base 301. When the two support blocks 401 have moved to their maximum outward distance, the knob 404 at the end of the second guide rod 402 is rotated, causing the outer side of the knob 404 to contact the baffle 406, thus effectively limiting the position of the support blocks 401. This completes the adjustment of the distance between the two support blocks 401, facilitating the processing of monocrystalline silicon rods of different radii. It is highly practical. Furthermore, the reinforcing rod 405 fixed to the side of the support block 401 is slidably connected to the slide groove 302, strengthening the movement of the support block 401. To ensure stability during operation, after supporting the bottom of the monocrystalline silicon rod, the four nuts 206 are rotated sequentially to initially adjust the position of the clamping block 205 according to the radius of the monocrystalline silicon rod, thereby reducing the extension distance of the hydraulic rod 208 and improving operating efficiency. Then, the hydraulic rod 208 on the support frame 207 drives the connecting plate 203 to move downward. The connecting plate 203 drives the first guide rod 202 to move downward along the inner wall of the mounting frame 201. The connecting plate 203 then drives the clamping block 205 at the center to press the monocrystalline silicon rod downward, thereby quickly clamping and fixing the monocrystalline silicon rod with strong stability. At the same time, when waste chips fall between the two support blocks 401 during the cutting process, since the internal space of the mounting base 301 is connected to the two inclined grooves 303 at the bottom, the waste chips falling into the mounting base 301 slide through the inclined grooves 303 to the storage boxes 304 on both sides of the bottom plate 1, avoiding the problem of blockage caused by waste chip accumulation and facilitating cleaning.
