Description

Technical Field

[0001] The utility model belongs to the technical field of blades and relates to a new type of tool. Background Art

[0002] Cutting tools are tools used for cutting in mechanical manufacturing. Most of the tools are machine tools, but there are also hand tools. Since the tools used in mechanical manufacturing are basically used to cut metal materials, the term "tools" is generally understood to mean metal cutting tools. Tools used to cut wood are called woodworking tools.

[0003] In the existing technology of cutting tools, there is still a problem that the blade of the tool becomes dull or damaged after long-term use, which makes it troublesome to replace the blade. Summary of the invention

[0004] The purpose of the utility model is to provide a new type of tool which is convenient for disassembly and assembly in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a new type of tool, including a blade seat, a blade body is provided at the front end of the blade seat, and a positioning slot for installing the blade body is provided at the front end of the blade seat, characterized in that a fixing rod is fixedly provided at the front end of the blade seat and at a position relative to the blade body, an opening for the fixing rod to pass through is provided on the blade body, a positioning piece for positioning the blade body is provided on the blade seat, a sliding component fixedly connected with the positioning piece and controlling the positioning piece to move up and down is provided in the blade seat, a through hole is provided in the blade seat and at a position relative to the sliding component, a positioning head is provided at the front end of the positioning piece, one end of the positioning head extends into the opening of the blade body and abuts against the upper end of the fixing rod, the sliding component is composed of a sliding rod and a reset spring, a sliding groove for sliding the sliding component is provided in the blade body, a sliding part for sliding up and down is provided on the sliding rod and relative to the sliding groove, and the reset spring is provided between the sliding part and the blade seat, and the sliding rod is moved up and down in the sliding groove by the action of the reset spring so that the positioning piece positions the blade body.

[0006] In the above-mentioned novel tool, the sliding part and the sliding rod are integrally formed, the positioning head and the positioning piece are integrally formed, and the fixing rod and the blade seat are integrally formed.

[0007] In the above-mentioned novel tool, the positioning member is fixedly mounted on the sliding rod by means of fixing bolts and is controlled by the sliding rod to slide up and down as the sliding rod slides up and down.

[0008] In the above-mentioned novel tool, the front end portion of the blade seat is arranged in an inclined structure.

[0009] Compared with the prior art, the new tool is connected to the sliding assembly inside the blade seat through a positioning piece, so that the positioning piece is controlled by the sliding assembly. Since the blade body is positioned by the positioning piece, the blade body can be detachably fixed through the sliding assembly, which is convenient for the operator to repair and replace the blade body and improves the use efficiency.
