The first gear 232 is coaxially sleeved on the output shaft 221 of the motor 22, and the diameter of the first gear 232 is smaller than that of the second gear 233, so that when the motor 22 rotates, the output shaft 221 can drive the first gear 232 to rotate, and then the second gear 233 is driven to rotate.
Eccentric wheel parts 2331 are respectively arranged at two opposite ends of the second gear 233, and the central axes of the two eccentric wheel parts 2331 do not overlap in the direction of the central axis of the second gear 233. The power transmission assembly 23 further includes two crank rods 239 respectively sleeved on the two eccentric wheel portions 2331, one end of each crank rod 239 is sleeved on the corresponding eccentric wheel portion 2331, and the other end is connected to the blade assembly 30, so that when the second gear 233 rotates, the crank rods 239 can be driven to move, and then the blade assembly 30 is driven to move back and forth to perform shearing operation. Preferably, the two crank rods 239 have one end connected to the eccentric wheel 2331 and the other end connected to the blade bar assembly 30, which are not overlapped at the center, so as to achieve stable power transmission.
In the present invention, the first and second bottom covers 2311 and 2312 are assembled by screw and screw holes being engaged with each other; of course, in other embodiments, the first bottom cover 2311 and the second bottom cover 2312 may be assembled and fixed by other methods, which is not limited herein. In addition, it is understood that the rotational connection between the first gear 232 and the second fan 230 and between the eccentric wheel portion 2331 of the second gear 233 and the crank lever 239 are implemented by the bearings 40, which is prior art and thus will not be described in detail.
The blowing chamber 236, the heat dissipating fins 234, and the heat dissipating passage 235 are formed at a side of the first bottom cover 2311 facing the housing assembly 21. Specifically, the heat dissipating fins 234 are formed on the first bottom cover 2311 and located at one side of the second fan 230, one end of the heat dissipating channel 235 is communicated with the blowing chamber 236, and the other end is communicated with the outside, when the motor 22 rotates, the second fan 230 rotates synchronously and drives the air in the accommodating cavity 2313 to be discharged outwards along the heat dissipating channel 235, in this process, heat on the motor 22, the power transmission assembly 23 and the heat dissipating fins 234 is taken away, and the heat dissipating efficiency of the pruner 100 of the present invention is improved.
