Abstract

The invention discloses a steel chisel beneficial for labor protection. The steel chisel includes a cylindrical striking part, a cylindrical pin body part and a pyramid shape drill head. The main characteristics of the steel chisel are as follows: the outer diameter end of the bottom part of the cylindrical pin body part is provided with an integrated form of c-ring; a compression spring is covered on the outer diameter end of the cylindrical pin body part below the c-ring; a hollow ball mask body is adjustably covered on the outer diameter end of the cylindrical pin body part below the compression spring; the cylindrical pin body part below the compression spring is provided with an external screw thread that is matched and connected with a flange nut; the compression spring is in a free style condition; a rubber gasket is covered on the outer diameter end of the cylindrical pin body part between the flange nut and the ball mask body; the outer diameter of the ball mask body is set at 10-15 cm; the material of the ball mask body is transparent organic glass. The steel chisel can avoid to the greatest extent the carved broken stones falling down to hit on the face of a worker. The steel chisel is especially suitable for carving characters and patterns on stone walls.

Description

technical field [0001] The invention relates to the technical field of steel brazing, in particular to a steel brazing which is beneficial to labor protection. Background technique [0002] Steel drills are often used in mines and construction sites to cut stones. It consists of a cylindrical knocking part, a cylindrical drill body and an integrally formed square cone drill head. However, the existing steel drills lack the necessary labor protection devices, especially when they are used to chisel characters and patterns on the stone wall, because the face of the operator is close to the stone wall, the chiseled gravel is very easy to hit the operator the face, and even fly into the eyes, causing accidental injury. Contents of the invention [0003] The purpose of the present invention is to provide a steel drill that can prevent the chiseled gravel from hitting the face of the operator as much as possible, and is especially suitable for use when chiseling characters and...
