Opposite-pulling type multifunctional double-strip steel saw

Abstract

The invention discloses an opposite-pulling type multifunctional double-strip steel saw. The opposite-pulling type multifunctional double-strip steel saw comprises a steel saw bow rack. A telescopic rod with a length adjusting spinning roller is transversely arranged in an inner cavity in the top of the steel saw bow rack. Sliding strips and limiting scales are sequentially arranged on the front face of the steel saw bow rack from interior to exterior. A fixed saw strip and a movable saw strip are connected to the inner cavity of the steel saw bow rack from bottom to top through connecting bolts. The steel saw is light in structure and diverse in function. Materials can be cut off in a labor saving manner through the fixed saw strip and the movable saw strip, the materials can be cut in the upper direction and the lower direction at the same time, and therefore the material cutting speed can be increased, and the material machining efficiency is improved. The length of the steel saw bow rack can be manually adjusted through cooperation of the telescopic rod, the sliding strips and the limiting scales, the length of the steel saw bow rack can be adjusted according to steel saw strips with different lengths, and it is not needed to arrange a plurality of steel saws at the same time.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a pair-pull multifunctional double hacksaw. Background technique [0002] A hacksaw is a commonly used tool and an essential tool for a master fitter. It is used to cut small-sized hardware materials such as round steel, angle steel, flat steel and workpieces. The hacksaw consists of two parts, a saw frame and a saw blade. During use, the saw blade is installed on the saw frame and then the saw frame is manually operated to cut materials such as steel and wood. Nowadays, different kinds of hacksaws have appeared widely on the market, which has brought great convenience to people's life and work. [0003] However, the functions of the hacksaws currently on the market are relatively single, and when saw blades of different lengths are used, the length of the hacksaw frame is fixed, so that the hacksaw frame must be replaced when the saw blade is replaced, and most of the ha...

Problems solved by technology

[0003] However, the functions of the hacksaws currently on the market are relatively single, and when saw blades of different lengths are used, the length of the hacksaw frame is fixed, so that the hacksaw frame must be replaced when the saw blade is replaced, and most of the hacksaws on the market are It is a single saw blade. When encountering a cutting material with high hardness, it is difficult for a single saw blade to quickly cut two sections of the material, and the cutting speed is slow, which is difficult to meet the needs of the market and people.
