Specific embodiment

In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, with Lower combination accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific reality described herein It applies example to be only used to explain the utility model, is not used to limit the utility model.

Also referring to Fig. 1 and Fig. 2, now chain saw provided by the utility model is illustrated.The chain saw, including start Machine 10, the starter with the driving axis connection of engine 10, and the saw blade 20 being connect with engine 10；Starter, which is externally provided with, to be opened Dynamic cover 30 (since starter setting is in starting cover 30, without display starter in Fig. 1 and Fig. 2, the structure of starter with The structure of starter in the prior art is identical), starting cover 30 is equipped with starting pull rod 40, further includes electric motor 60 and setting Shaft coupling 50 on the input shaft of starter；The output shaft 61 of electric motor 60 is detachably connected with shaft coupling 50.

Electric motor 60 is hand electric motor, and compact structure, convenient for hand-held, electric motor 60 is only in starting engine It is connect before 10 with shaft coupling 50, when which works normally, electric motor 60 is not connect with shaft coupling 50.

Engine 10 is petrol engine, and petrol engine is equipped with fuel tank.

The start-up course of the engine of chain saw provided by the utility model is as follows:

The output shaft 61 of electric motor 60 is connect with shaft coupling 50, starts electric motor 60, electric motor 60 passes through connection Axis device 50 starts starter, and then starts engine 10, and after start completion, electric motor 60 exits the connection with shaft coupling 50. In addition, engine 10 can also be started by starting pull rod 40, Starting mode is same as the prior art.

Chain saw provided by the utility model, compared with prior art, engine 10 can directly be opened by electric motor 60 Dynamic, Starting mode is time saving and energy saving.In addition, when 60 short of electricity of electric motor or electric motor 60 be not in use site, engine 10 It can also be started by starting pull rod 40, to guarantee the chain saw normal use.
