Through the support block 6, a U-shaped groove structure can be formed in part of the first limiting groove 4. When drilling holes in the circular pull rod, the arc groove of the support block 6 is fitted to the outer surface of the running pull rod, so that the outer surface of the circular pull rod obtains more support and fixing points, reducing the activity of the pull rod; an anti-skid plate 7 is fitted in the arc groove of the support block 6, and the convex strip design of the support block 6 increases the friction with the pull rod, thereby And improve the anti-skid effect of the pull rod; the connecting rod 8 is fixed on both sides of the top of the support block 6, and each group of support blocks 6 is connected and fixed to each other. A groove is opened on the surface of the workbench 2 corresponding to the position of the connecting rod 8, so that the connecting rod 8 can enter the groove. One end of the connecting rod 8 is connected by a fixed plate. When drilling the rectangular pull rod, the support blocks 6 are uniformly taken out from the first mounting groove 5 through the connecting rod 8, so that there is no obstruction inside the first limiting groove 4, which facilitates the stable placement of the rectangular pull rod. When drilling the circular pull rod, each group of support blocks 6 is simultaneously placed in the first mounting groove 5 through the anti-slip plate 7, so that a U-shaped groove is formed in part of the first limiting groove 4. After the circular pull rod is placed in the first limiting groove 4, the bottom of the first limiting groove 4 falls in the arc groove at the top of the support block 6, supporting the circular pull rod, and the arc groove can fit the surface of the circular pull rod to the maximum extent, providing more stable support for the circular pull rod.

[0029] A puncher 3 is provided on the top of the support plate 1. The top of the puncher 3 is connected to a screw rod through a cylinder. The screw rod drives the cylinder to move, so that the cylinder can drive the puncher 3 to drill holes at different positions of the pull rod.

[0030] Symmetrical second mounting grooves 9 are provided on both sides of the inner wall of the first limiting groove 4, and the second mounting grooves 9 are located between each group of first mounting grooves 5. A push plate 10 is installed inside the second mounting groove 9, and a support rod is fixed on the side of the push plate 10 away from the first limiting groove 4, and a compression spring 11 is sleeved on the outer surface of the support rod. Through the two symmetrical groups of push plates 10, the pull rod placed inside the first limiting groove 4 is centered to ensure the accuracy of the punch 3 when drilling holes.

When processing the circular pull rod, the support block 6 is installed into the first installation groove 5. When fixing the pull rod, the adjustment plate 15 is lifted upward to make the top of the first limiting groove 4 open. The pull rod is directly placed into the first limiting groove 4 from the top of the first limiting groove 4, so that the bottom of the pull rod falls on the inner surface of the anti-slip plate 7, thereby increasing the supporting and fixing effect of the circular pull rod. After the pull rod enters the first limiting groove 4, the push plate 10 is pushed by the compression spring 11. The pull rod is moved to center the pull rod and limit the pull rod at the same time. After the pull rod is located in the first limit groove 4, the positions between the groups of movable rods 13 are adjusted according to the drilling position of the pull rod to avoid the position where the pull rod needs to be drilled. Then the adjustment plate 15 is pressed down to make the movable rod 13 located on the top of the workbench 2, and the pressure plate 14 at the bottom of the movable rod 13 falls to the top surface of the pull rod through the thrust of the compression spring 11, which limits the pull rod again, strengthens the fixing effect of the pull rod, reduces the activity problem when the pull rod is drilled, and ensures the qualified quality of the pull rod drilling.
