Problems solved by technology
However, the existing traditional starting device has many disadvantages: (1) The pull rope is directly and rigidly connected with the starter handle, so that the pull rope often bears the instantaneous impact tension and is in danger of being broken; (2) The pull rope is due to the production process For this reason, most of them are directly exposed to the air after being knotted, and the life of the rope head will be shortened due to aging

Embodiment Construction
[0014] refer to figure 1 , 2 , which is a kind of engine starter handle with a buffer mechanism disclosed in the present invention, one end of the pull rod 10 is connected with a handle 11, the pull rod 10 is provided with a drawstring hole 12 passing through its two ends, and the handle 11 is matched with the drawstring hole 12 A rope groove 13 connected to the rope hole 12 is provided at the position of the rope, and a rubber buffer seat 14 is arranged in the rope groove 13 and sealed with the rope groove 13, and the rubber buffer seat 14 is provided with through holes 15 through both sides. A rope guide hole 16 communicating with the through hole 15 is provided on the side of the rubber buffer seat 14 corresponding to the draw rope hole 12 , and the axis of the guide rope hole 16 intersects or is perpendicular to the axis of the through hole 15 . Since the top of the rubber buffer seat 14 is fully enclosed, and its shape design matches the pull rope groove 13 of the starte...

The invention relates to the technical field of engines, in particular to an engine starting handle with a buffering mechanism. The engine starting handle comprises a pull rod and a handle body connected with one end of the pull rod. A rope pulling hole is formed in the pull rod and is throughout the two ends of the pull rod, a rope pulling groove communicated with the rope pulling hole is formed in the position, matched with the rope pulling hole, of the handle body, the rubber buffering base combined with the rope pulling groove in a sealed mode is arranged inside the rope pulling groove, a penetrating hole is formed in the rubber buffering base and is throughout the two sides of the rubber buffering base, a rope guiding hole is formed in the side, corresponding to the rope pulling hole, of the rubber buffering base and communicated with the penetrating hole, and the axis of the rope guiding hole and the axis of the penetrating hole intersect with each other or are perpendicular to each other. The engine starting handle has the advantages that the time interval, for a pull rope, from no stress to bearing of large impact pull force is increased by 6-10 times, the risk of breaking the pull rope is reduced, and meanwhile the engine starting handle is an orientated closed device and can isolate a pull rope knot from the external world, so that the rope head is prevented from aging.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to an engine starting handle with a buffer mechanism. Background technique [0002] Small engines usually need to manually pull the starter handle to start manually. The handle is directly connected to the starting pull rope. The pull rope drives the rope wheel to rotate during starting, and the rope pulley drives the engine flywheel to rotate synchronously. Due to the huge inertia of the engine flywheel, The crankshaft and connecting rod of the engine are driven to rotate synchronously, and at the same time, the rotation of the flywheel makes the igniter start to ignite the cylinder combustion chamber, and the engine starts to run normally. However, the existing traditional starting device has many disadvantages: (1) The pull rope is directly and rigidly connected with the starter handle, so that the pull rope often bears the instantaneous impact tension, and there is a danger of b...
