[0024] The first positioning plate 11 is installed on the top of the mounting frame 10 by welding, so that the mounting frame 10 is aligned with the first positioning plate 11, thereby keeping the first positioning plate 11 in a horizontal state and improving the stability of the first positioning plate 11. By setting multiple trapezoidal positioning grooves 12 on the first positioning plate 11, the first positioning plate 11 can position and accommodate the round shaft to be drilled by positioning the grooves 12. By setting multiple empty tool grooves 13 in the first positioning plate 11 and connecting the multiple empty tool grooves 13 to the multiple positioning grooves 12, when drilling the round shaft, the drill bit can be embedded in the empty tool grooves 13, thereby avoiding interference between the drill bit and the first positioning plate 11 and improving the user experience of the product. By welding the support plate 14 onto the mounting bracket 10 and positioning it below the first positioning plate 11, the mounting bracket 10 supports the support plate 14, thereby keeping the support plate 14 horizontal and improving its stability. By mounting the clamping mechanism 15 onto the support plate 14 and connecting the clamping plate 16 to it, positioning the clamping plate 16 above the first positioning plate 11, the support plate 14 supports the clamping mechanism 15. This allows the clamping mechanism 15 to move the clamping plate 16 up and down, pressing multiple round shafts into the first positioning plate 11, thus improving the stability of the round shafts and facilitating drilling.
