[0028] Specifically, before the bevel flange is placed on the upper surface of the base 1 for processing, the bevel flange is pushed to move, and the outer surface of the bevel flange is respectively fitted on the inner walls of the four groups of arc-shaped limit plates 203, and then the bevel ring 202 is pushed to clamp the positioning ring 201 inside the mounting groove of the base 1, so that the bevel ring 202 is fitted on the inner wall of the bevel flange, and then the clamping mechanism 2 can clamp the bevel flange to the upper end of the base 1 in a single clamping process, thereby minimizing the impact of repeated clamping on the processing speed of the bevel flange, thereby improving the practicality of the device.

[0029] like Figure 1 and Figure 2As shown, the limiting mechanism 4 includes a telescopic rod 405 and a bidirectional threaded rod 401, the bidirectional threaded rod 401 is rotatably connected to the inside of the two groups of through holes of the base 1, the external thread of the bidirectional threaded rod 401 is connected to the two groups of sliders 402, a positioning groove is provided at the bottom of the inner wall of the base 1, the two groups of sliders 402 are slidably connected to the inside of the positioning groove of the base 1, the front of the two groups of sliders 402 are installed with connecting rods 403, and the adjacent sides of the two groups of connecting rods 403 are provided with limiting rods 404, the left and right sides of the positioning ring 201 are provided with through holes, the positions of the two groups of through holes of the positioning ring 201 are respectively located on the moving paths of the two groups of limiting rods 404, the end of the bidirectional threaded rod 401 away from the base 1 is installed with a telescopic rod 405, and the side of the telescopic rod 405 away from the base 1 is installed with a handle 406;

[0030] Specifically, after the positioning ring 201 is clamped in the installation groove of the base 1, the handle 406 is pushed to drive the telescopic rod 405 and the bidirectional threaded rod 401 to rotate, so that the bidirectional threaded rod 401 drives the two groups of sliders 402, the two groups of connecting rods 403 and the two groups of limit rods 404 to move synchronously during the rotation, and then the positions of the two groups of through holes of the positioning ring 201 are respectively located on the moving paths of the two groups of limit rods 404, so that the two groups of limit rods 404 are inserted into the two groups of through holes of the positioning ring 201 during the movement, so that the limiting mechanism 4 limits the moving position of the bevel ring 202 at the upper end of the base 1 during use, thereby improving the stability of the clamping mechanism 2 during use.

[0031] like Figure 3 and Figure 4 As shown, the positioning mechanism 6 includes an L-shaped limit rod, which is installed on the front side of the telescopic rod 405. A fixed block 602 is arranged on the side of the L-shaped limit rod close to the base 1. A groove is provided on the side of the base 1 close to the L-shaped limit rod, and the position of the internal groove of the base 1 is located on the moving path of the fixed block 602; specifically, when the staff connects the two groups of limit rods 404 to the two groups of through holes of the positioning ring 201, the telescopic rod 405 is pushed to drive the L-shaped limit rod and the fixed block 602 to move, and the fixed block 602 is inserted into the groove of the base 1, so that the positioning mechanism 6 limits the rotation position of the telescopic rod 405 and the bidirectional threaded rod 401 during use, thereby minimizing the movement of the two subsequent groups of limit rods 404 during use, thereby improving the stability of the limit mechanism 4 during use.

[0034] In summary: by pushing the beveled flange to move, the outer surface of the beveled flange is respectively fitted on the inner walls of the four groups of arc-shaped limit plates 203, and then by pushing the beveled circular ring 202, the positioning circular ring 201 is clamped inside the mounting groove of the base 1, so that the beveled circular ring 202 is fitted on the inner wall of the beveled flange, and then the clamping mechanism 2 can clamp the beveled flange to the upper end of the base 1 in a single clamping process, thereby minimizing the impact of repeated clamping on the processing speed of the beveled flange; by pushing the handle 406 to drive the telescopic rod 405 and the double The threaded rod 401 is rotated so that the bidirectional threaded rod 401 drives the two groups of sliders 402, the two groups of connecting rods 403 and the two groups of limit rods 404 to move synchronously during the rotation. Then, the two groups of through holes of the positioning ring 201 are respectively located on the moving paths of the two groups of limit rods 404, so that the two groups of limit rods 404 are inserted into the two groups of through holes of the positioning ring 201 during the movement, thereby allowing the limit mechanism 4 to limit the moving position of the bevel ring 202 on the upper end of the base 1 during use.

[0035] At the same time, by pushing the telescopic rod 405 to drive the L-shaped limit rod and the fixing block 602 to move, the fixing block 602 is inserted into the groove of the base 1, so that the positioning mechanism 6 limits the rotation position of the telescopic rod 405 and the bidirectional threaded rod 401 during use, thereby avoiding the subsequent two groups of limit rods 404 from moving during use; by pushing the positioning ring 201, the two groups of connecting blocks 5 are clamped in the two groups of clamping grooves of the base 1, so that the two groups of connecting blocks 5 limit the position of the positioning ring 201 installed in the mounting groove of the base 1 each time, so that when subsequent staff members open holes for multiple groups of beveled flanges, the positions of the opening marks left on the outer surface of the beveled ring 202 are the same, thereby avoiding the subsequent staff members opening multiple groups of holes on the outer surface of the beveled ring 202 when opening holes on the front side of the beveled flange, causing damage to the beveled ring 202.
