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 arranged in the machine case, a chain wheel driven by the motor, a guide plate arranged on the machine case, a sawing chain arranged on the chain wheel and the guide plate, a sawing chain cover plate, and an anti-rebound shield including a holding part and a pivotal shaft part. The pivotal shaft part includes a stretching part. The anti-rebound shield has a first position and a second position enabling devices respectively to be in a brake state and a non-brake state, and is characterized in that a locking part is installed on the anti-rebound shield, the sawing chain includes a cooperation part, when the anti-rebound shield is arranged in the first position, the locking part is partially detached from the cooperation part, and when the anti-rebound part is arranged in the second position, the locking part is partially meshed with the cooperation part. The above structure prevents operators from accidentally removing the sawing chain cover plate when the devices are in the non-safety state, and effectively improves the security of the chain saw use.

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...
