Description
Technical field
The utility model relates to garden equipment field, and more particularly, it relates to the operating mechanism on a kind of mower.
Background technology
Mower (Lawnmower) is also known as weeder, grass mower, lawn mower etc.Mower be a kind of for cutting the grass on a lawn, the machine tool of vegetation etc., it is made up of cutterhead, engine, road wheel, running gear, blade, handrail, control section.
Existing mower is divided into hand-push type and self-propelled two kinds, and without any power on hand-push type mower road wheel, its walking promotes to advance entirely artificially; Self-propelled mower is provided with clutch on road wheel, utilize the bent axle on engine to connect belt wheel to be connected with the belt wheel on clutch, be pull conjunction that clutch handrail realizes clutch and the rotation point realizing road wheel by people, unlatching from walking modes descendant be controlling party to.The mower of prior art is from walking device, there is clutch, there is stepless speed changing mechanism, control respectively by drag-line, this is the technical scheme that the public knows well, and certainly also have the clutch certainly walked in device of clutch and stepless speed changing mechanism one, on market, ubiquitous mower all only has a kind of speed to regulate, namely clutch handrail is pulled to realize, from walking device and close to make mower be adjusted to from walking modes, after bleeding off clutch handrail, being adjusted to hand push pattern from the clutch separation walked in device.
The pace controlling mower is regulated commercially to occur the mechanism of many stepless speed regulation for realizing an infinitely variable speeds, such as at the walking infinitely variable speeds governor motion that application number is a kind of lawn machine disclosed in the Chinese patent of 201320557212.0, by from arranging variable velocity zone wheels between belt wheel and main pulley, variable velocity zone wheels are connected with main pulley with from belt wheel with the second speed change edge-cutting belt with low first speed change edge-cutting belt respectively, the infinitely variable speeds that the contact radius pulling gear change hand lever to drive zip line to change two speed change edge-cutting belts realizes lawn machine regulates, well-known this infinitely variable speeds governor motion is by leading, existing leading is compared from arranging variable velocity zone wheels between belt wheel, all deposit structurally complicated from arranging a regulating wheel between belt wheel, and need to do significantly corresponding improvement to chassis, and then increase manufacturing cost.
Be in the patent document of 200910207840.4 for solving the problem the applicant at application number, by rotating from walking device tensioning driving belt, increase and realize infinitely variable speeds with the frictional force of belt pulley, the process of rotating from walking device drives drag-line by clutch handrail, drag-line is connected with from walking device, namely speed regulation process determines the pace of mower by aperture between drag-line and handrail, because clutch handrail is generally located at the side of rear near people of handrail, speed regulation process needs people's backhand to pull, and in this process, pull startup handrail again, operation inconvenience, be not easy to the pace controlling mower.
Utility model content
For the deficiency that prior art exists, first object of the present utility model is to provide the operating mechanism that a kind of structure is simple, convenient operation meets the mower of body mechanics.
For achieving the above object, the utility model provides following technical scheme:
A kind of operating mechanism of mower, comprise promotion handrail, the holding part between the long handle portion, left and right that described promotion handrail is rearward extended by lawnmower chassis and two long handle portions forms, and it is characterized in that, described operating mechanism is positioned at the upper side promoting handrail, comprising:
Start handrail, be rotationally connected with the long handle portion, left and right promoting handrail, described startup handrail is connected with the clutch cable of lawn mower engine;
