[0029] Working principle description:

[0030] The basic function of this device is the same as that of the utility model patent entitled "A multi-angle burr removal device for metal cutting materials" (application number 202310595951.7). The device fixes the metal handrail through a metal clamping mechanism, moves the metal handrail through a transmission mechanism, and grinds the burrs of the metal handrail through a burr grinding mechanism. It is worth noting that first, the clamp 11 is pushed and the pressing plate 17 is pressed down, so that the groove 16 set on the first slide 10 matches the limit block 15, and then the support frame 14 pops out under the action of the second spring 13, and at the same time When the metal handrail needs to be fixed, the handle 20 is pulled to separate the second rack 22 set on the second slider 19 from the first rack 12, and the metal handrail is placed on the pressure plate 17. The metal handrail presses down the pressure plate 17, and the limit block 15 comes out of the groove 16. Therefore, after the clamp 11 is released from the restriction, the clamp 11 clamps the metal handrail under the action of the first spring 9, and the handle 20 is released. The second slider 19 rebounds under the action of the second spring 13 to match the second rack 22 with the first rack 12 to achieve the limiting effect on the clamp 11.

[0031] Preferably, a rubber cushion layer is provided on the first chute 6. Such a structural design reduces the friction damage to the first chute 6 and prolongs the service life of the equipment.

[0032] Preferably, a rubber cushion layer is provided on the second chute 7. Such a structural design reduces the friction damage to the second chute 7 and prolongs the service life of the equipment.

[0033] Preferably, a rubber cushion layer is provided on the third chute 8. Such a structural design reduces the friction damage to the third chute 8 and prolongs the service life of the equipment.

[0034] Preferably, the handle 20 is provided with anti-slip grooves. Such a structural design makes the handle 20 more convenient to operate.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
