Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

In this embodiment, referring to fig. 1-3, a simple drilling machine includes a mounting box 1 and a steel pipe 11, wherein a double-headed screw 2 and two single-headed screws 3 are disposed in the mounting box 1, the double-headed screw 2 is disposed above, the single-headed screw 3 is disposed at corresponding positions on two sides of the lower part, and corresponding spin handles 12 are respectively connected to the ends of the double-headed screw 2 and the single-headed screw 3 through respective transmission shafts.

The two sides of the rod body of the double-head screw rod 2 are respectively connected with a nut pair A4 in a threaded transmission manner, a connecting column A5 downwards extends from the bottom of the nut pair A4, connecting columns A5 positioned at two sides are respectively arranged in the inner sides of the steel pipes 11, a nut pair B8 is respectively connected to the single-head screw rod 3 in a threaded transmission manner, a connecting column B9 downwards extends from the bottom of the nut pair B8, connecting columns B9 positioned at two sides are respectively positioned at the outer sides of the steel pipes 11, clamping blocks 6 are arranged at the bottom of the connecting column A5, and the clamping blocks 6 positioned at the same side are positioned flush with the perforating machine 10. The bottom of the connection column B9 is provided with a punch 10, and the steel pipe 11 is drilled by the punch 10. As shown in fig. 3, the side of the clamping block 6 facing the inner wall of the steel pipe 11 is designed as an arc surface 13, and the arc surface 13 is provided with a avoiding hole 7 for the drill bit of the puncher 10 to pass through.

The cambered surface 13 is designed to ensure that the clamping block 6 can be fully attached to the inner wall of the steel pipe 11 in the process of continuously adjusting the position, and meanwhile, the design of avoiding the hole 7 can also prevent the drilling tool of the puncher 10 from damaging the clamping block 6.

In addition, as shown in fig. 1, it is also specifically proposed that the bottom surface of the mounting case 1 is provided with a through groove 14 for the two connecting posts A5 and B9 to slide back and forth.

It should also be mentioned that the bottom surface of the installation box 1 is also provided with a rubber pad 15, and the installation box 1 is pressed against the pipe orifice of the steel pipe 11 through the rubber pad 15.
