Safety chain saw

Abstract

The invention discloses a safety chain saw which comprises a body and a saw chain. A gripping portion is arranged on the body and is provided with a starting switch, a cover plate is arranged on a side surface of the body, a quadrant arc-shaped groove is formed in a certain position of the body, the cover plate covers the certain position of the body, the side walls of the arc-shaped groove are made of insulating materials, one end of the arc-shaped groove is positioned at the lowest point, the other end of the arc-shaped groove is positioned at a horizontal point, a mounting portion in the shape of a circular truncated cone is arranged at the end, which is positioned at the lowest location, of the arc-shaped groove, an iron ball is arranged on the upper side of the mounting portion, the mounting portion comprises a half circular truncated cone A and a half circular truncated cone B, the circular truncated cone A is close to the end of the arc-shaped groove as compared with the half circular truncated cone B, insulating treatment is carried out between the half circular truncated cone A and the half circular truncated cone B, and an alarm switch is arranged at the other end of thearc-shaped groove. The safety chain saw has the advantages that the safety chain saw is simple and reliable in structure, convenient to manufacture and low in cost and is provided with safety protection structures, and accordingly workers can be prevented from being accidentally injured when using the safety chain saw.

Description

technical field [0001] The invention relates to the technical field of chain saws, in particular to a safety chain saw. Background technique [0002] The chain saw is a kind of demolition equipment, mainly used for logging and lumber making. Its working principle is to perform cutting action by the lateral movement of the interlaced L-shaped blades on the saw chain. According to the function and driving mode, it can be divided into motorized chainsaws. Chainsaws are generally divided into motorized chainsaws and non-motorized chainsaws. [0003] Chain saws are divided into different sources according to the same principle: gasoline saws, electric saws, pneumatic saws, and hydraulic saws. The advantages and disadvantages of these four power chain saws are more obvious. [0004] Gasoline saw: It is highly mobile and suitable for mobile work in the field, but it is noisy, troublesome to maintain, and generates more heat. [0005] Electric chain saw: stable power, quick start,...

AI Technical Summary

Problems solved by technology

At present, there is a chain saw, which lacks safety protection measures. When the worker works for a long time, the arm will have a sore and numb physiological reaction under the influence of the vibration of the chain saw. When the worker can't hold on, the palm of the hand can still hold the chain saw handle, but the strength of the arm has been unable to support the overall weight of the chain saw normally

Therefore, the chain saw will center on the part held by the palm, turn and fall, and at this time, the worker's body may be injured.

In addition, when cutting special objects, if the chain saw jumps violently, workers may be accidentally injured
