Abstract

The invention belongs to the field of multifunctional non-electric combined control devices of internal combustion engines, and particularly relates to a combination switch for an internal combustionengine-driven work machine. The combination switch comprises a switch seat, a fuel switch, an inhaul cable, an inhaul cable rotating shaft, a gear structure and a switch handle; the fuel switch is connected with the switch seat, and the inhaul cable is sleeved with a sleeve; the fuel switch is provided with a non-cylindrical switch rotating shaft, a toggle piece in on-off fit with a microswitch controlling a flameout switch is arranged on the switch rotating shaft in a linkage mode, and the inhaul cable rotating shaft is provided with a non-cylindrical connecting hole matched with the switch rotating shaft; the end, away from the fuel switch, of the switch rotating shaft penetrates through the connecting hole and is statically connected with the switch handle, thus, the switch handle and the switch seat form a structure for surrounding the inhaul cable rotating shaft and the gear structure together; and the sleeve is clamped and fixed with the switch seat. According to the scheme, theproblems of complex structure and inconvenient maintenance of the combination switch in the prior art are solved.

Description

technical field

[0001] The invention belongs to the field of non-electric combined control devices with multiple functions of an internal combustion engine, and specifically relates to a combination switch for an internal combustion engine-driven operating machine. Background technique

[0002] Combination switch for internal combustion engine-driven operating machinery, including fuel switch, cable for controlling choke, micro switch for controlling flameout switch, gear position structure and switch handle for operation, which generally includes start gear, running gear And the stop gear, some will also set the relevant oil gear, the fuel switch, the cable and the micro switch can be operated at the same time through the switch handle, so as to achieve the purpose of reducing the user's operation steps; in different gears, its functions are roughly as follows:

[0003] ①Starting gear: make the fuel switch in the open position, the choke valve in the closed position, and th...
