Chain saw with manual and electric double-starting system

Abstract

The invention discloses a chain saw with a manual and electric double-starting system. The chain saw comprises a starting assembly, a flywheel assembly, an engine driving assembly and an chain saw shell, wherein the starting assembly is connected with the flywheel assembly and drives the flywheel assembly to move, the flywheel assembly is connected with the engine driving assembly, the flywheel assembly and the engine driving assembly are arranged inside the chain saw shell, the starting assembly is arranged on the chain saw shell, the starting assembly comprises a starting wheel, a starter body, a manual starting assembly and an electric starting assembly, wherein the starting wheel is arranged on the starter body, and the manual starting assembly, the electric starting assembly is correspondingly connected with the starting wheel and drives the flywheel assembly to move through the starting wheel. The manual starting assembly and the electric starting assembly are connected with theflywheel assembly through the starting wheel, the internal structure of the starting assembly is simplified, the requirement for concentricity of the starter and the flywheel assembly is also reducedthrough connection of the starting wheel and the flywheel assembly, and the machining difficulty is lowered.

Description

technical field [0001] The invention relates to a chain saw, in particular to a chain saw with a flashlight double starting system. Background technique [0002] Existing hand-held portable chainsaws are almost all powered by a two-stroke gasoline engine, and the starting method is mainly based on manual starting, which is single and laborious to start. After improvement, the electric starting method has become a more labor-saving structural form. The specific structure is that a ring gear is installed on the outer ring of the flywheel, and a starter motor for starting is arranged on the chain saw, and an external power supply is used to provide energy to start the chain saw. , but only realized the increased weight of the starting function and increased the user's labor load. In order to improve the portability of the machine, it was later improved to adopt the starting method of an external starter motor. Generally, the starting transmission structure is set at the starte...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the disadvantages in the prior art that the starting systems of the manual starting and the electric starting modes are independent, the starting structure is compact, the concentricity of the starter and the rotary flywheel is relatively high, and the safety hazard of the electric starting joint is relatively large, etc., and provides A new kind of chainsaw with flashlight double starting system
