Abstract

The invention belongs to the technical field of mowers and particularly relates to a tool apron. The tool apron comprises a mounting seat and is characterized in that the mounting seat is produced bydie casting through a powder metallurgy process, a connecting seat is arranged at one end of the mounting seat, a mounting protrusion and positioning protrusions for tool mounting are arranged at theother end of the mounting seat, a plurality of annular stress grooves are formed in the mounting seat, and the annular stress grooves are arranged around the periphery of the mounting protrusion/positioning protrusions. The tool apron is simple in structure, convenient to produce and small in internal stress during production.

Description

technical field [0001] The invention belongs to the technical field of lawnmowers, in particular to a knife seat. Background technique [0002] The lawn mower is a common garden tool. The lawn mower cuts the grass and trees through the high-speed rotating blade. Due to the unreasonable structure of many lawn mower knife seats, the internal stress in the knife seat is relatively large during the production process, and the knife seat is prone to cracks during the production process, which affects the qualified rate and service life of the product. Contents of the invention [0003] In order to overcome the deficiencies and existing problems of the prior art, the present invention provides a tool holder with simple structure, convenient production and less internal stress during the production process. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A tool holder, including a mounting seat formed by die-casting...
