High-speed steel cutter suitable for plastic window angle clearing

Abstract

The invention discloses a high-speed steel cutter suitable for plastic window angle clearing. The high-speed steel cutter includes a cutter seat, a high-speed steel cutter body and a guarding block. The guarding block is of a C-shaped structure. The ends, closed to each other of the guarding block and the cutter seat are provided with cutter grooves. The upper end of the high-speed steel cutter body is inserted into the cuter groove in the lower end of the cutter seat. The lower end of the high-speed steel cutter body is inserted into the cutter groove in the upper end of the guarding block. The two sides of the upper end of the guarding block are provided with transverse grooves. One ends of the transverse grooves are located in the upper end of the guarding block. The other ends of the transverse grooves are located in the outer side of the cutter seat. The other ends of the transverse grooves are internally in inserted connection with one ends of first transverse blocks. The arranged cutter seat facilitates using of the high-speed steel cutter body, the cutter seat is located above the high-speed steel cutter body, the length of the whole device is shortened, and the whole device is convenient to carry; and double fixing is formed for the guarding block by arranging the first transverse blocks and a limiting rod, so that the guarding block is firmly connected with the cutterseat, and the use safety of the whole device is improved.

Description

technical field [0001] The invention relates to the technical field related to sharp steel knives, in particular to a sharp steel knife suitable for clearing corners of plastic windows. Background technique [0002] Fenggang is an alloy steel with complex composition, containing carbide forming elements such as tungsten, molybdenum, chromium, vanadium, etc. Fenggang knife is a cutting tool with high hardness. Plastic windows are made of polyvinyl chloride or resin as the main raw material. Add a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., extrude into shaped materials, and then make door and window frame leaves by cutting, welding or screwing, equipped with sealing strips, wool strips, Hardware, etc. The doors and windows made in this way are called plastic-steel doors and windows. In the prior art, when installing plastic-steel doors and windows, it is generally necessary to use a sharp steel knife to cut the remaining rubber strips o...

AI Technical Summary

Problems solved by technology

[0004] 1. The overall structure of the front steel knife is too long, which is inconvenient to use and carry;

[0005] 2. The front steel knife needs a scabbard for protection to prevent the front steel knife from accidentally injuring people when it is not in use, but the existing scabbard does not have a good fixed structure, which makes the front steel knife a potential safety hazard
