Problems solved by technology

[0002] At present, when the existing chain saws are sawing, wood chips or other impurities are usually adhered to the sawing chain. These impurities are usually thrown out by the inertial force of the impurities during the rotation of the sawing chain. Due to the limitation of the inertial force, there are usually certain impurities still adhering to the sawing chain. Obviously, this will lead to low sawing efficiency on the one hand, and affect the service life of the sawing chain on the other hand.

Embodiment Construction

[0023] Such as figure 1 , 2, 3, and 16 show that the chain saw of a preferred embodiment of the present invention comprises a casing 2, a rear handle 1 connected to the rear end of the casing 2, and a rear handle 1 fixedly mounted on the casing 2 and close to the casing 2 The front handle 6 of the front end of the front end, an anti-rebound shield 4 is firstly rotated and mounted on the front end of the casing 2, and the casing 2 forms a long axis X extending along the front and rear handle directions. The chain saw also includes a motor 3 installed in the casing 2, the motor 3 has a motor shaft (not shown in the figure), preferably, the Y axis is perpendicular to the X axis. A sprocket 10 is installed on the output shaft 34 along the Y-axis direction, and the motor 3 drives the sprocket 10 to rotate through a transmission mechanism connecting the output shaft 34 and the motor shaft. The transmission mechanism can be a planetary gear structure or other reduction gears institu...

Abstract

The invention provides a chain saw, which comprises a machine case, a motor, a fan, a chain wheel, a guide plate, a sawing chain and an air passage, wherein the motor is arranged in the machine case, the fan is driven by the motor, the chain wheel is driven by the motor, the guide plate is arranged on the machine case, the sawing chain is arranged on the chain wheel and the guide plate, the air passage is formed in the machine case, the first end of the air passage is near the fan, and the second end of the air passage is near the sawing chain. When an air passage mechanism of the chain saw is adopted, the sawing efficiency is improved, and the service life of the sawing chain is prolonged.

Description

technical field [0001] The present invention relates to a chain saw. Background technique [0002] At present, when the existing chain saws are sawing, wood chips or other impurities are usually adhered to the sawing chain. These impurities are usually thrown out by the inertial force of the impurities during the rotation of the sawing chain. Due to the limitation of the inertial force, there are usually certain impurities still adhering to the sawing chain. Obviously, this will lead to low sawing efficiency on the one hand, and also affect the service life of the sawing chain on the other hand. Contents of the invention [0003] The technical problem solved by the invention is to provide a chain saw, which improves the sawing efficiency of the chain saw and the service life of the sawing chain. [0004] In order to solve the above technical problems, the present invention provides: a casing, a motor installed in the casing, a fan driven by the motor, a sprocket driven by...
