Cutting blade and cutting tool

Abstract

The invention relates to the field of metal cutting tools, in particular to a cutting blade and a cutting tool. The cutting tool comprises a tool handle, a tool body and blades, the tool body is of a flat structure, and the blades are arranged on the two sides of the tool body. The tool handle comprises sliding blocks, elastic pieces, a rubber sleeve and a fixing shaft. One end of the fixing shaft is fixedly connected with the middle of one end of the tool body, and the other end is sleeved with the rubber sleeve. Sliding grooves are formed in the outer wall of the rubber sleeve. T-shaped blocks are slidably connected into the sliding grooves. The T-shaped blocks are fixedly connected with the corresponding sliding blocks. The sliding block close to the tool body is fixedly connected with the rubber sleeve. Every two adjacent sliding blocks are fixedly connected through the elastic pieces. The two adjacent sliding blocks are driven to get close to each other by pressing the elastic pieces with the finger, so that the sliding blocks completely wrap the outer contour surface pressed by the finger and extending into the position between the two adjacent sliding blocks, the effect that the tool is not prone to falling off when held by the hand is achieved, and then the safety in the production working process is improved.

Description

technical field [0001] The invention relates to the field of metal cutting tools, in particular to a cutting blade and a cutting tool. Background technique [0002] Cutting tools are tools commonly used for cutting in machinery manufacturing; most of the cutting tools are machine-used, but some are also hand-used; In the case of burrs, deburring treatment is required. Compared with machine deburring, manual deburring does not require technical treatment, saves costs and is environmentally friendly. Manual deburring cutting tools mainly include two parts: the knife handle and the knife body. Hands will sweat after long-term high-intensity work. The sweaty hands will not hold the knife handle tightly and fall off or even hurt the hand. This will affect the normal work and personal safety of the workers. Different workers have different finger thicknesses, so it is necessary to Hold the cutting tool as tightly as possible to facilitate the worker's work. [0003] For example,...

Problems solved by technology

[0003] For example, a Chinese patent with the application number CN210359620U discloses a plane scraper, including a cutter head, a fixed cutter rod, an extended cutter rod and a handle, wherein: the first end of the cutter head and the fixed cutter rod are embedded connected and locked by screws; the second end of the fixed knife rod is detachably connected to the first end of the extended knife rod; the second end of the extended knife rod is detachably connected to the handle , this technical solution solves the technical problem that in the prior art, in order to meet the technical needs of rough scraping and fine scraping, a large number of scrapers and different lengths need to be prepared, causing inconvenience to carry; but this technical solution is not on the fixed knife bar The opening of the groove does not take into account that different people have different finger thicknesses, which will affect the stability of the worker holding the cutting tool, and then the cutting tool may fall off after the worker's palm sweats, which will affect the worker's safety, which makes the present invention have limitations. sex
