Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

Examples are given.

See fig. 1-3.

The embodiment discloses a brick chisel which is used for cutting bricks in the construction process and comprises a cutter 1, a chisel rod 2, a bearing seat 3 and a handle 4. The cutter 1 is in a rectangular sheet shape, the edge of the bottom of the cutter 1 is a cutter edge part 11, and the hardness of the cutter 1 is as high as 45HRC after the high-frequency heat treatment process, so that the cutter 1 cannot be easily damaged when the brick is cut.

In this embodiment, the bearing seat 3 is cylindrical, a through groove is formed in the bottom of the bearing seat, the forming direction of the through groove is perpendicular to the axis direction of the bearing seat 3, the bearing seat 3 is installed on the top of the cutter 1 through the through groove, and the bearing seat 3 is fixedly connected with the cutter 1 through welding.
