Chain saw for preventing accidents

Abstract

The invention discloses a chain saw for preventing accidents. The chain saw comprises a body and a saw chain, wherein the body is internally provided with a starter; a side surface of the body is provided with a cover plate, the body is provided with a work control part which is internally provided with an arc groove, the arc groove is connected with a pressing plate installation part, and the pressing plate installation part is rotationally provided with a first pressing plate and a second pressing plate; a first ferrous pressing plate covers the other end of the arc groove, a first pressure-bearing switch and a magnet are arranged on the work control part and located at the first pressing plate, and the magnet is closer to the gyration center axis than the first pressure-bearing switch;the second pressing plate is provided with a second pressure-bearing switch, a side wall of the pressing plate installation part is provided with a pressure-bearing table, and the pressure-bearing table is positioned between the second pressure-bearing switch and the side wall of the pressing plate installation part. The chain saw is simple and reliable in structure, convenient to manufacture andlow in cost, has a safety protection structure, and can be used for preventing accidental injury to workers during use.

Description

technical field [0001] The invention relates to the technical field of chainsaws, in particular to a chainsaw preventing accidents. 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, ...

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
