Problems solved by technology

[0002] The existing new building masonry knives are usually monolithic. The vibration of the hands of construction workers is particularly large when cutting bricks on the masonry wall, which often causes accidents such as cracking and vibration injuries of the hands. Poor performance, uncomfortable operation and other problems have plagued construction workers for a long time and have not been resolved; in the process of building walls, sometimes it is necessary to use a plumb hammer to check whether the verticality of the wall is qualified, and the existing building The block knife does not have the function of detecting the verticality of the wall

Abstract

The invention discloses a novel building masonry knife, and relates to a building tool. The novel building masonry knife comprises a knife body, a knife handle and a grip, wherein the knife handle is arranged in the grip; a groove is sunken in the tail end of the grip; an auxiliary grip is arranged outside the groove; the auxiliary grip is in threaded connection with the grip; a thin line is arranged in the groove; one end of the thin line is fixedly connected into the groove, and the other end of the thin line is fixedly connected onto the auxiliary grip; and a tooth-shaped auxiliary knife edge is arranged on the knife back of the knife body. The novel building masonry knife disclosed by the invention has the advantages of being reasonable in structure, low in labour intensity, high in safety, comfortable to operate, and the like; and moreover, the novel building masonry knife further has a function of detecting whether the perpendicularity of the built wall body is qualified or not, and is quite practical.

Description

technical field [0001] The invention relates to a construction tool, in particular to a novel construction knife. Background technique [0002] The existing new building masonry knives are usually monolithic, and the vibration of the hands of construction workers is particularly large when cutting bricks on the masonry wall, which often causes accidents such as cracking and vibration injuries of the hands. Poor performance, uncomfortable operation and other problems have plagued the construction workers for a long time and have not been resolved; in the process of building walls, sometimes it is necessary to use a plumb hammer to check whether the verticality of the wall is qualified, and the existing building The masonry knife does not have the function of detecting the verticality of the wall. Contents of the invention [0003] Aiming at the deficiencies of the prior art above, the present invention provides a new type of building masonry knife with reasonable structure...
