Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, and particularly relates to a circular tube punching auxiliary tool. Background Art

[0002] In the field of machining in modern industry, in many cases, it is necessary to manually punch holes in circular pipe fittings. When manually punching holes, a hand-held electric drill is required for drilling. When drilling on a circular tube, the front end of the drill bit cannot be positioned, resulting in problems such as slipping between the drill bit and the circular tube, breakage of the drill bit, and deviation of the punching position. For example, the instrument panel beam inside the car cab is a metal circular pipe fitting, and multiple process holes need to be opened on the beam. The process holes determine the assembly and positioning accuracy of the instrument panel. However, during the actual drilling process, due to the slipping phenomenon between the drill bit and the circular tube, the hole positions deviate. Existing circular tube punching methods include using laser cutting holes, manually scribing and punching positioning points for drilling, and using a special round hole drill template for auxiliary drilling, etc. However, the existing technologies have the following disadvantages: Laser cutting holes in circular tubes is costly, and a special auxiliary positioning template device needs to be made, which affects the punching efficiency of circular tubes. Manually scribing and punching positioning points for drilling in circular tubes is slow in scribing speed, inaccurate in scribing, slow in punching positioning points, too long in auxiliary drilling time, poor in accuracy, low in efficiency, and not good in operability. And using a special round hole drill template for auxiliary drilling in circular tubes requires making a special round hole drill template, which has poor versatility, high precision requirements for making the drill template, high wear rate, high cost, and inconvenient use. Therefore, the existing technologies have limitations. Content of the Utility Model

The second arc-shaped claw is connected to one end of the first handle through a first pivot shaft and can cooperate with the first arc-shaped claw to form a jaw. One end of the second handle is connected to the second arc-shaped claw through a second pivot shaft. The second handle is connected to the first handle through a connecting plate. One end of the connecting plate abuts against the adjusting bolt. One end of an elastic member is connected to one end of the second arc-shaped claw, and the other end is connected to the middle of the first handle. A fixing member is arranged in the through hole, and external threads and internal threads that mesh with each other are respectively arranged on the outer wall of the fixing member and the inner wall of the through hole; wherein, a plurality of teeth are evenly distributed on the opposite arc-shaped surfaces of the first arc-shaped claw and the second arc-shaped claw.
