[0061] like Figure 19 and Figure 20As shown, the third transmission 5 includes two coaxial two-stage planetary gears arranged on the motor 6, the ratchet disc 413, the ratchet knob 412, the starting wheel 421, the reset member and the passive wheel 424 are replaced by two-stage planetary gears, a torsion spring is arranged between the planetary gears and the starting ratchet 422, the motor 6 is coaxially arranged with the two-stage planetary gears, that is, the motor 6 is perpendicular to the starter cover 1, and the motor 6 is located on the outer surface of the starter cover 1.

[0062] It can be seen that the transmission can be implemented in various ways, so that the selection is large.

[0063] In the fourth embodiment, a circuit board is arranged on the mounting seat 7, the circuit board contains a mos tube (field effect transistor), a power supply is plugged on the circuit board, the circuit board is respectively connected with the motor 6 and the starting switch 3, which is convenient for installation and disassembly of the power supply and replacement, the mos tube (field effect transistor) on the circuit board limits delay, and the service life is greatly improved. Further, the power supply adopts a battery pack, which is convenient for replacement in the later period. Further, the mounting seat 7 is located on one side of the starter cover 1, which ends the phenomenon that the power supply is placed in the air and is damaged by falling in the prior art, and the service life of the power supply is greatly prolonged.

[0064] In the fifth embodiment, the present application further provides a chainsaw, which comprises a chainsaw body, and the electric starter described above is mounted on the chainsaw body, and in the embodiment, the electric starter is fixed on the chainsaw body by a fixing member, specifically, the electric starter is fixed on the flywheel of the chainsaw body by the fixing member, and the fixing member is a bolt, a screw or a screw, etc., so that the user can manually install and disassemble the electric starter, which is conducive to large-scale promotion and application.

[0065] Further illustrate, the flywheel position of the chainsaw body increases a stator coil, so that the original one stator coil becomes two stator coils, and the stator coils are connected with the high-voltage package (containing a chip) in the chainsaw body, and the circuit board 12 is arranged on the inner wall of the starter cover 1, and the circuit board 12 is connected with the power supply, wherein when the flywheel and the high-voltage package rotate during the operation of the machine, a high-voltage electricity of 300 volts is generated to charge the battery package, and the circuit board 12 functions as rectification and voltage reduction (voltage stabilization). Further illustrate, the circuit board 12 can be integrated into the high-voltage package (containing a chip) in the case of being small enough, which is beneficial to save space and reduce the cost of manufacturing the starter cover 1. One is the original stator coil, which can amplify a 20-kilovolt stator coil (voltage coil) to break the spark plug ignition, and now a small stator coil (voltage coil) can generate a voltage of one or two hundred volts, which is controlled by the high-voltage package (containing a chip) and rectified by the circuit board 12 to generate a small current in the battery package. During the use of the chainsaw, a certain power is generated, which is rectified and stabilized by the rectifier and stabilizer on the circuit board 12 to charge the battery package, and the power is about 2w-3w, 21V, and the current is about 0.1A. During the starting process, about 50A is needed, and the consumption time is very short (3 seconds). In theory, only 25 minutes of continuous use of the machine is needed to fully charge the battery package for the next start, which can reduce the battery capacity, reduce the charger and reduce the cost. Because the chainsaw body (the chainsaw itself) has a high-voltage package, its function can generate a certain magnetic flux to generate an electric current when the flywheel rotates, and then amplify the high voltage through the stator coil. The chip in the high-voltage package can check its speed through the power generation time interval, so as to control the speed range of 2500-12000, and realize reverse charging.

[0066] When the manual handle 2 is started, the handle 2 drives the starting rope to rotate the starting rope wheel 411 counterclockwise, so that the starting rope wheel 411 drives the starting wheel 421 and the starting ratchet 422 to rotate counterclockwise through the cooperation of the ratchet knob 412 and the ratchet disc 413, so that the starting ratchet 422 can drive the flywheel in the chainsaw to rotate and start, and the chainsaw starts to work. This kind of opening starts the manual starting mode, and when the handle 2 is released, the down winding spring in the starting rope wheel 411 can rotate clockwise to reset, so that the starting rope wheel 411 rotates clockwise to reset, and the handle 2 is reset.

[0067] When the present application is started by starting switch 3, starting switch 3 will start motor 6, motor 6 will drive driving wheel 522 through planetary reducer 521, driving wheel 522 engages transmission driven wheel 424, driven wheel 424 drives starting wheel 421 to rotate, starting wheel 421 will drive starting ratchet wheel 422 to rotate counterclockwise, starting ratchet wheel 422 can drive the flywheel in the chainsaw to rotate and start, the chainsaw starts to work, because ratchet handle 412 and the ratchet disc 413 on the starting wheel 421 are in a disengaged state, so that the starting wheel 421 can only rotate counterclockwise alone, and the starting rope wheel 411 will not rotate (is static), this is to achieve the electric starting mode. Pressing or short pressing the starting switch 3 is limited by the circuit board to limit the starting time, to achieve the purpose of protecting the motor 6, which is beneficial to prevent overheating.
