Embodiment Construction

[0031] refer to Figure 1-7 , is an engine recoil starter disclosed in the present invention, the return coil spring 2 and the retaining cover 21 are installed in the starter case 1 together, and the outer ring end 3 of the return coil spring 2 is fixed on the starter In the case 1, the end 4 of the inner ring of the return coil spring 2 is stuck in the groove 6 of the starting sheave 5, the starting sheave 5 is set on the center column 7 of the starting case 1, and one end of the pull rope 8 is fixed In the hole in the rope groove 9 on the starting sheave 5, the other end is fixed on the starting handle 10 outside the starter case 1, and the stay rope 8 can drive the starting sheave 5 to rotate under the action of external force, and the starting sheave 5 When rotating, the ratchet wheel on the starting sheave 5 drives the flywheel to rotate, and at the same time the starting sheave 5 rotates to shrink the return coil spring 2. After the external force is canceled, the return...

Abstract

The invention relates to the technical field of engines, in particular to an engine recoil starter. The engine recoil starter comprises a return spiral coil spring, a starting rope sheave and a ratchet which are disposed in a starter housing, wherein an elastic connecting device is disposed between the starting rope sheave and the ratchet; the elastic connecting structure is characterized in that an auxiliary starting plate is disposed between the starting rope sheave and the ratchet, the ratchet is disposed on the auxiliary starting plate, an energy accumulation spring is disposed between the auxiliary starting plate and the starting sheave, the two tips of the energy accumulation spring are respectively fixed on the corresponding lateral sides of the starting sheave and the auxiliary starting plate, and the ratchet is disposed on the other lateral side of the auxiliary starting plate. The engine recoil starter has the advantages that the starter is in reliable transmission and clutch with an engine, small in size, capable of correspondingly reducing the shape of the whole starter, easy in starting, labor saving, small in vibration, and high in use comfortableness.

Description

technical field [0001] The present invention relates to the technical field of engines, in particular to a hand-held garden tool powered by a small air-cooled engine, such as: brush cutters, chain saws, hedge shears, etc. The starter is installed on the same side of the flywheel blade, that is, It relates to an engine recoil starter. Background technique [0002] The small gasoline engine with pull-start is simple in structure and light in weight, and is widely used in hand-held garden tools. The crankshaft of the engine begins to rotate under the external force of the hand starter to the whole process of the automatic idling of the engine, which is called the starting process of the engine. A general recoil starter is composed of a starter cover, a return coil spring, a starting handle, a pull rope, and a starting sheave. Engageable, the flywheel is fixed to the crankshaft. When starting the engine, hold the starter handle tightly and pull the pull rope, the pull rope dr...
