Description

Technical Field

[0001] The utility model relates to the technical field of starters, in particular to a clamping fixture for a hand-pulled starter. Background Art

[0002] The working principle of the hand-pulled starter is to pull the starter handle to drive the starter wheel with the starter rope to rotate. The starter wheel toggles the starter dial connected to the crankshaft of the gasoline engine, driving the crankshaft of the engine, causing the piston to reciprocate, and the combustible mixture in the cylinder burns and expands to do work, pushing the piston downward to rotate the crankshaft. The engine thus transitions from a stationary state to a working state, and the working cycle proceeds automatically. At this time, the starter dial rotates with the engine crankshaft, and the starter claw on the starter dial is separated from the starter wheel under the action of centrifugal force. The starter wheel compresses the return spring while toggling the starter dial. After the starter starts the engine, its starter wheel, pull rope, handle, etc. return to the starting position under the action of the return spring.

[0003] There is no good clamp in the production and processing of the starter, which makes it inconvenient to fix the starter during processing, which easily causes the starter to shake, and the clamping surface of the clamping plate will be worn after long-term use. In order not to affect the clamping effect, it is usually necessary to replace the clamp as a whole. This integrated replacement will cause a waste of resources. The clamping plate cannot be replaced independently, and there are certain limitations. In view of the above problems, the inventor proposes a hand-pull starter clamping fixture to solve the above problems. Utility Model Content
