Groove 11 and spring groove 12, the spring groove 12 is fixedly installed with hanging rods 17 at the positions near the two ends of the opening of the spring groove 12, the upper end of the inner cylindrical surface of the inner chuck 6 is evenly distributed in a circle with three claw grooves 20, the claw grooves 20 are slidably connected with claws 8, the claws 8 are rotatably connected to the outer chuck 5 at one end away from the center of the inner chuck 6, and the claws 8 are rotatably connected to the outer chuck 5 at one end close to the center of the inner chuck 6. A brake mechanism 3 is provided at the cantilever end on the left side of the U-shaped frame 2.

[0020] By adopting the above technical solution, the outer chuck 5 is clamped on the U-shaped frame 2 and rotated in the vertical direction, so that the angle of the rubber ring during processing can be adjusted. The outer chuck 5 and the inner chuck 6 are respectively connected to the claws 8, so that the inner chuck 6 can drive the claws 8 to rotate when it rotates relative to the outer chuck 5. The three claws 8 are simultaneously away from or close to the circular rubber ring.

[0021] The brake mechanism 3 includes a threaded handle 15, the middle part of which passes through the cantilever of the U-shaped frame 2 and extends to the rear side of the cantilever of the U-shaped frame 2, and the rear end of the threaded handle 15 is rotatably connected to an arc-shaped brake block 16, the width of the arc-shaped brake block 16 is adapted to the width of the space at the cantilever of the U-shaped frame 2 where it is located, and the arc surface of the arc-shaped brake block 16 facing the center of the arc is provided with gear teeth.

[0022] By adopting the above technical solution, the width of the arc brake block 16 is adapted to the gap width at the cantilever of the U-shaped frame 2, preventing the arc brake block 16 from rotating with the threaded handle 15, and the gear teeth on the arc surface of the arc brake block 16 can engage with the brake teeth 14 of the rotating rod 10 to prevent the rotating rod 10 from rotating.

[0023] A steering handle 21 is fixedly installed on the outer cylindrical surface of the inner chuck 6 corresponding to the handle groove 11, and a spring connector 22 is fixedly installed on the outer cylindrical surface of the inner chuck 6 corresponding to the spring groove 12. The spring connector 22 is rotatably connected to a contraction spring 18, and the end of the contraction spring 18 away from the spring connector 22 is rotatably connected to a hook 19.

[0024] By adopting the above technical solution, the inner chuck 6 can be rotated in the outer chuck 5 by rotating the steering handle 21, and the spring connector 22 is rotatably connected with the contraction spring 18 so that the contraction spring 18 can change the force direction, and the hook 19 can be hung on the hanging rod 17 on one side to change the tendency of the claw 8 to expand or contract.

[0025] A circular inner plate slide groove 13 is provided at the lower end of the inner cylindrical surface of the outer chuck 5 , and the inner plate slide groove 13 is slidably connected to the inner chuck 6 .

[0026] By adopting the above technical solution, the inner disk slide groove 13 can limit the relative movement of the inner chuck 6 and the outer chuck 5, thereby improving stability.

[0027] The left rotating rod 10 among the rotating rods 10 passes through the cantilever of the U-shaped frame 2 and extends to the rear end of the arc-shaped brake block 16. The circumferential surface of the rotating rod 10 located at the part covered by the arc-shaped brake block 16 is provided with a brake tooth 14, and the brake tooth 14 meshes with the gear teeth of the arc-shaped brake block 16 when they approach each other.

[0028] By adopting the above technical solution, the braking of the outer chuck 5 is exerted by the cooperation between the arc-shaped braking block 16 and the braking teeth 14 of the rotating rod 10 .

[0029] The middle part of the claw 8 extends toward its side, and is slidably connected with the claw groove 20 at its extended part.

[0030] By adopting the above technical solution, the rotating wheel 9 and the clamping claw 8 are distributed in a triangular shape at the connection between the inner chuck 6 and the outer chuck 5, thereby increasing the stroke.

[0031] A handrail 7 is fixedly mounted on the front side of the outer cylindrical surface of the outer chuck 5 .

[0032] The rotating wheel 9 is made of rubber and the outer surface of the middle part is concave inwards.

[0033] By adopting the above technical solution, the rotating wheel 9 is made of rubber, which can better fit and avoid damaging the rubber ring. The concave shape in the middle can make the positioning more stable. At the same time, the rotation of the rotating wheel 9 can make the rubber ring rotate during processing without processing dead angles.

[0034] Working principle: When the utility model is in use, the technician rotates the threaded handle 15 to move the arc brake block 16 away from the rotating rod 10, and its gear teeth are away from the brake teeth 14 of the rotating rod 10, thereby loosening the rotating rod 10, and then rotates the outer chuck 5 to adjust it to a suitable angle through the handrail 7, and then rotates the threaded handle 15 in the opposite direction to make the arc brake block 16 engage with the brake teeth 14 on the rotating rod 10 to fix the angle of the outer chuck 5, and then hangs the hook 19 at the end of the contraction spring 18 into a suitable hanging rod 17 according to the processing needs, so as to determine whether the positioning requirement of this processing is to expand the inner ring of the rubber ring from the inside to the outside or from the outside The outer ring of the rubber ring is squeezed inward to achieve the purpose of positioning and clamping. When the hook 19 is hung on the hanging rod 17, the tension on one side of the contraction spring 18 is applied, so that the inner chuck 6 has a tendency to rotate clockwise or counterclockwise relative to the outer chuck 5. Thereafter, the steering handle 21 is pulled, and the inner chuck 6 obtains a force temporarily opposite to the tension applied by the contraction spring 18. Subsequently, the rubber ring to be processed is placed on the plane of the rotating wheel 9 and the steering handle 21 is released. The claw 8 resumes rotation to position the rubber ring from the inside or outside. At the same time, the rubber ring can be directly rotated during processing. The rubber ring fits the rotating wheel 9 and can rotate freely to prevent the rotating wheel 9 from blocking the area from being processed.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
