Claims

[Scope of claim for utility model registration] 1. A pipe is clamped from above and below by a lower clamp and an upper clamp, and the upper clamp is provided with a female thread with a fine lead, and a male thread is screwed into the female thread. It is a tool for making a hole in the surface of the clamped pipe by screwing together a formed drill and rotating the drill, and the tool has square pillars installed vertically on the side of the lower mold clamp, and the periphery of the square pillar is A holding sleeve is provided integrally with the upper mold clamp so that it can slide up and down the prism, and rack plates formed with tooth profiles that engage with the drilled sides of the sliding portion are opposed to each other, and one rack plate is attached to the inner surface of the sleeve. The other rack plate is installed loosely at the front and rear of the square column, and a female thread is provided that penetrates from the back of the rack plate inside the square column to the back surface of the square column, and a bolt with a handle is inserted into the female thread from the back surface of the square column. A punching machine characterized in that a lower mold clamp and an upper mold clamp are connected by screwing them together, pressing a loosely fitted rack plate, and engaging the rack plate on the inner surface of the sleeve. 2. Claim 1 of the Utility Model Registration Claims: The rack plate installed inside the square column is always attached to the square column side by engaging a bolt with the rack plate and interposing a spring between the bolt head and the square column. A drilling machine characterized by being pulled together. 3. Claims for Utility Model Registration, as stated in Paragraph 1, have a clamp bolt that is screwed into an internal thread provided on the upper clamp body, and the upper clamp seat is connected to the end of the bolt, and the lower clamp bolt is tightened by tightening the clamp bolt.
