Technical field

The utility model relates to a kind of accessory of motorcycle carburetor, especially a kind of motorcycle carburetor with extension bar screw of draining the oil.

Background technique

At present, the public motorcycle carburetor screw of draining the oil need be unscrewed and tighten, and to drain in the Carburetor Residual oil and the full fresh oil of storage again, guarantees that motor normally starts.The motorcycle carburetor screw of draining the oil is assemblied in the left side or the right side of Carburetor bottom, blocked by the covering of motorcycle both sides, and pedal motorcycle carburettor draw off screw especially, it is covered fully by motorcycle covering component; On the motorcycle covering component of corresponding carburettor draw off screw side, be provided with a technology aperture, can only pass this aperture with the lengthening bottle opener and realize unscrewing of carburettor draw off screw and tighten.Its deficiency is that the carburettor draw off screw is invisible, is unfavorable for bottle opener aligning carburettor draw off screw, and the feasible screw of draining the oil turns difficulty, even just can't turn the screw of draining the oil at the period of the day from 11 p.m. to 1 a.m that extended at all.And, because this screw of draining the oil is invisible, turn when draining the oil screw with the lengthening bottle opener, destroy than the notch that is easier to the screw of draining the oil, the screw that just will cause draining the oil is scrapped, even the very difficult screw of will draining the oil turns.

Summary of the invention

The utility model is at the drain the oil above-mentioned deficiency of screw of the motorcycle carburetor of prior art, and its objective is provides a kind of motorcycle carburetor with extension bar screw of draining the oil.It has overcome the invisible screw of draining the oil that causes of carburettor draw off screw effectively and has turned difficulty, and has reduced and turn the dependence of screw to long bottle opener of draining the oil.

The technical solution of the utility model: the motorcycle carburetor screw of draining the oil of band extension bar, comprise the screw of draining the oil, it is characterized in that: the top at the described screw of draining the oil is provided with opening slot, the connection termination of extension bar is goed deep in the opening slot and is connected, and makes extension bar can drive the screw of draining the oil and rotates synchronously;

Further feature is: at the exposed junction of extension bar, the bottle opener notch of " one " font or " ten " font is set;

The profile of the exposed junction of extension bar is square or hexagonal shaped.

The motorcycle carburetor of the utility model band extension bar screw of draining the oil with respect to prior art, has following characteristics:

1, the extension bar exposed junction end of carburettor draw off screw is provided with the shared screw-driver slot of one word/cross, and the exposed junction profile is four directions or six sides, directly just can turn the screw of draining the oil with bottle opener or spanner by the exposed junction that turns extension bar.

2, not only overcome the invisible screw of draining the oil that causes of carburettor draw off screw and turned difficulty, and reduced and turn the dependence of screw of draining the oil long bottle opener instrument.

3, it is very convenient to turn the screw of draining the oil, and the drain the oil notch of screw of protection prolongs its working life.
