Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a hole-opening device for construction. Background Art

[0002] Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc. The place where the construction work is done is called "construction site" or "construction site", also called construction site.

[0003] In the construction of buildings, a process of drilling holes in certain parts of the building body is included. There is an electric drilling machine with a Chinese patent publication number of CN207086975U. The structure is simple and reasonable, and it is easy to use. The dust and fragments generated by drilling are isolated in a collection room, and the dust does not come into contact with the air, thereby ensuring the visibility of workers during construction, avoiding environmental pollution, and ensuring human health. The fragments fall directly into the storage bag, keeping the ground clean and tidy, and avoiding workers from stepping on the fragments and scratching the ground. At the same time, the collection room is a closed structure, ensuring that the fragments will not roll down to the output shaft of the drilling machine, ensuring the normal operation of the output shaft; and the drilling depth is ensured by the fixing block and the fastening bolts on the ruler, avoiding the problem of excessive deviation of the drilling depth due to manual operation errors.

[0004] However, due to the lack of support, the opening grip is unstable and has poor reliability. Utility Model Content
