Therefore, this structural design can meet the requirements for drilling U-shaped channel steel of various sizes.
[0024] Example: Figure 1 , Figure 2 and Figure 4As shown, this utility model provides a technical solution for a drilling device for channel steel of duct support. The drilling structure includes a mounting plate 18, which is rotatably connected to the outside of a fixed base 1. An external gear ring 24 is fixedly connected to one side of the mounting plate 18.

[0026] Example: Figure 1 - Figure 3 As shown, the adjustment structure includes a bidirectional screw 12, which is disposed inside the convex groove 11 and rotatably connected to the fixed seat 1.

One end of each L-shaped plate 15 is fixedly connected to an L-shaped rod 16, and one end of each L-shaped rod 16 passes through the outside of the fixed seat 1 and extends into the rectangular groove 3. Both L-shaped rods 16 are slidably connected to the fixed seat 1, and one end of each L-shaped rod 16 is fixedly connected to a limit plate 17.
[0027] Specifically, when the second throttle is turned, the second worm gear 14 meshes with the second worm wheel 13. The second worm wheel 13 drives the double-acting screw 12 to rotate. The double-acting screw 12 is threadedly connected to the two L-shaped plates 15. The two L-shaped plates 15 drive the two L-shaped rods 16 to slide on the fixed seat 1, and the two L-shaped rods 16 drive the two limiting plates 17 to move in opposite directions inside the rectangular groove 3. Therefore, the position of the two limiting plates 17 can be adjusted. The two limiting plates 17 can limit the two sides of the U-shaped channel steel, which can improve the stability of the fixing block 10 in fixing the U-shaped channel steel and avoid deflection during drilling.
