[0025] The driving assembly 5 includes a slide plate 503 , and the slide plate 503 is slidably disposed inside the first U-shaped seat 1 .

[0026] Among them, the driving component 5 also includes a shaking handle 501, a driving screw 502 and a limiting slider 504, the slide plate 503 is threadedly connected to the driving screw 502, the front end of the driving screw 502 is fixedly connected to the shaking handle 501, and the end of the driving screw 502 away from the shaking handle 501 passes through the limiting slider 504 and is rotatably connected to the inner wall of the No. 1 U-shaped seat 1. By rotating the shaking handle 501, the driving screw 502 can be effectively driven to rotate synchronously, and by rotating the driving screw 502, the slide plate 503 can be moved back and forth along the driving screw 502.

[0027] Among them; a strip groove 101 is opened in the middle end of the upper surface of the No. 1 U-shaped seat 1, and a limit slider 504 is clamped in the center of the upper end of the slide plate 503. The upper end of the limit slider 504 passes through the strip groove 101 and is fixedly connected to the No. 1 bracket 3. The limit slider 504 is slidably connected to the inner wall of the strip groove 101. The slide plate 503 moves back and forth, and the limit slider 504 can drive the No. 1 bracket 3 to move back and forth synchronously, thereby effectively adjusting the distance between the No. 1 bracket 3 and the No. 2 bracket 301, so as to facilitate the micro-concave roller 4 to be inserted into or pulled out of the shaft hole at the upper end of the No. 2 bracket 301 away from the mounting shaft at one end of the No. 1 bracket 3.

[0028] Among them; the clamping assembly 6 includes a strip top plate 601, a vertical rod 602 and a limiting plate 603. The strip top plate 601 is arranged above the pressing block 302. Two vertical rods 602 are provided. The two vertical rods 602 are respectively fixedly arranged on the two ends of the lower end surface of the strip top plate 601. Side ears 303 are fixedly arranged on both sides of one end where the No. 1 bracket 3 and the pressing block 302 are close to each other. A through hole is opened in the center of the side ear 303. The lower end of the vertical rod 602 is fixedly connected to the limiting plate 603 through the through hole. The side ear 303 is provided to facilitate the installation of the clamping assembly 6, and the limiting plate 603 is used to prevent the clamping assembly 6 from detaching from the No. 1 bracket 3.

[0029] Among them; the center thread of the strip top plate 601 is connected with a clamping screw 604, the lower end of the clamping screw 604 is provided with a pressure plate 605, and the upper end of the clamping screw 604 is provided with a rotating rod 606. By rotating the rotating rod 606, the clamping screw 604 can be driven to rotate upward or downward. When the clamping screw 604 rotates and moves downward, it drives the pressure plate 605 to move downward synchronously. Under the limiting action of the limiting plate 603, the pressure plate 605 pushes the pressure block 302 to press the No. 1 bracket 3, effectively limiting the position of the mounting shaft at the end of the micro-concave roller 4. The overall operation is simple, time-saving and labor-saving, and it is convenient to disassemble in the later stage, and no other tools or auxiliary operations are required.

[0030] Among them, fixing holes 7 are provided on the bottom plates of the No. 1 U-shaped seat 1 and the No. 2 U-shaped seat 2. By providing the fixing holes 7, it is convenient to install and fix the No. 1 U-shaped seat 1 and the No. 2 U-shaped seat 2 to ensure the overall stability.

[0031] Working principle: when replacing the micro-concave roller 4, by rotating the rotating rod 606, the clamping screw 604 can be driven to rotate and move upward. When the clamping screw 604 rotates and moves upward, the pressure plate 605 no longer squeezes the pressure block 302, and the pressure block 302 can be lifted up to separate from the No. 1 bracket 3. The overall operation is simple.

[0032] Furthermore, by turning the shaking handle 501, the driving screw 502 can be effectively driven to rotate synchronously. By driving the screw 502 to rotate, the slide plate 503 can be moved backward along the driving screw 502. By moving the slide plate 503, the No. 1 bracket 3 can be driven to move backward synchronously through the limit slider 504, thereby effectively expanding the distance between the No. 1 bracket 3 and the No. 2 bracket 301, making it easy for the micro-concave roller 4 to be pulled out of the axial hole at the upper end of the No. 2 bracket 301 away from the mounting axis at one end of the No. 1 bracket 3, and disassembling the micro-concave roller 4 does not require the use of other tools to assist the operation, which is simple to operate and saves time and effort.
