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

Abstract

The invention discloses a chain saw capable of avoiding injuries of workers. The chain saw comprises a body and a saw chain, wherein a starter is arranged in the body, a holding part is arranged on the body and is provided with a starting switch, a cover plate is arranged on one side surface of the body, an arc-shaped groove accounting for one fourth of a circle is formed in the body, a truncatedcone-shaped mounting part is arranged at the end part of the lowest position of the arc-shaped groove, and an iron ball is mounted above the mounting part; a guiding arc is arranged at the part, abovethe mounting part, of the arc-shaped groove and produces a guide function when the rolling ball leaves the mounting part; a light ray emitter is arranged in the mounting part, a mounting groove is formed in the position, right above the mounting part, of the guiding arc, a light ray receiver is arranged in the mounting groove, the light ray receiver is matched with the light ray emitter to work,and the light ray receiver and the light ray emitter are connected with the starter. The chain saw is simple and reliable in structure, convenient to manufacture and low in cost, has a safe protectionstructure and can avoid accidental injuries of the workers during use.

Description

technical field [0001] The invention relates to the technical field of chain saws, in particular to a chain saw that prevents workers from being injured. 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 cha...
