Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tire production and relates to a handheld shaving knife frame. Background Art
[0002] With the rapid development of the automobile industry, tires, which are essential for vehicle driving, have also been widely developed. Automobile tires are rubber products. After being formed, the tire embryos need to be vulcanized in the mold at high temperature and high pressure. On the surface of the vulcanized tire, the tread and sidewall will produce rubber edges and rubber columns. Such rubber edges and rubber columns not only affect the appearance of the tire, but also seriously affect the dynamic balance of the tire. Therefore, it is necessary to use cutting tools such as razors for trimming.
[0003] The traditional razor device can be used by fixing the blade on the blade holder. The blade edge is composed of a number of triangular sharp teeth. During the trimming process, the tire rotates at high speed and there is unstable shaking, so the tip of the triangular teeth is easy to shave and scratch the tread, affecting the quality of the tire. Summary of the invention
[0004] The utility model aims to provide a handheld razor holder, which can solve the problem that the triangular blade tip is easy to shave and scratch the tread.
[0005] According to the technical solution provided by the utility model: a handheld razor holder comprises a handle, which is connected to a blade through a fixing unit; the blade comprises a mounting portion and a blade portion, the blade portion is provided with a plurality of V-shaped grooves, and V-shaped teeth are formed between adjacent V-shaped grooves; the fixing unit is composed of a guide head and a connecting seat connected to each other; a plurality of guide grooves are provided on one side of the lower part of the guide head, and a positioning portion is provided on the other side; a blade connecting plate is provided in the middle of the connecting seat, and side plates are provided on both sides of the blade connecting plate; one end of the side plate is connected to the positioning portion; an adjustment connection structure is provided between the blade connecting plate and the blade.
[0006] As a further improvement of the present invention, the side panels are arranged in an L-shaped structure, and the positioning portions are matched with the ends of the side panels.
[0007] As a further improvement of the utility model, the adjustment connection structure includes matching blade connection holes and adjustment waist grooves, the two blade connection holes are symmetrically arranged in the middle of the mounting portion, and the adjustment waist grooves are symmetrically arranged on the blade connection plate.
[0008] As a further improvement of the utility model, the bolt passes through the adjusting waist groove and the blade connecting hole in sequence and then is connected to the nut to complete the connection between the blade connecting plate and the blade.
[0009] As a further improvement of the utility model, the blade connecting hole is a through hole.
[0010] As a further improvement of the utility model, the outer side of the lower part of the guide head adopts an arc surface structure.
[0011] As a further improvement of the utility model, one end of the shank is fixedly connected to the top of the guide head by a welding process.
[0012] The positive effects of this application are:
[0013] The utility model prevents the blade from contacting the tire surface during shaving and scratching the tire surface, thereby ensuring that the trimmed tire will not be scratched and having a low wear rate. BRIEF DESCRIPTION OF THE DRAWINGS
