Because the handle assembly 10 and the blade assembly 30 are of conventional construction, they will not be described in detail herein, and the power mechanism 20 will be described in detail in the following sections of the specification.
Referring to fig. 6 to 10 in combination with fig. 3, the power mechanism 20 includes a housing assembly 21, a motor 22 accommodated in the housing assembly 21, and a power transmission assembly 23 mounted on the housing assembly 21. The housing assembly 21 includes a first housing 211, a second housing 212, and a top cover 213 covering over the first housing 211 and the second housing 212. In the present invention, the top cover 213 is a metal top cover, the first housing 211 and the second housing 212 are both metal housings, the first housing 211 is fixed to the handle assembly 10, and the second housing 212 is fixed to the first housing 211. Of course, the top cover 213 may be a plastic top cover, as long as the same function is achieved, and is not limited thereto.
The first housing 211 includes a bottom housing 2111 and a side portion 2112 protruding from the bottom housing 2111 toward the handle assembly 10, a mounting cavity 2113 is formed in the bottom housing 2111, and the motor 22 is mounted in the mounting cavity 2113. The bottom shell 2111 is further provided with a plurality of fixing holes 2114, and the fixing holes 2114 penetrate through the bottom shell 2111 and are communicated with the mounting cavity 2113, so that the screws 40 can penetrate through the fixing holes 2114, and the bottom shell 2111 and the power transmission assembly 23 can be fixed by means of the screws 40.

The metal top cover 213 is mounted to the bottom housing 2111 and covers over the motor 22 to close the mounting chamber 2113. The metal top cover 213 is integrally formed with a heat dissipation surface 2131, and the first housing 211 and the second housing 212 are combined to form a metal housing, so that heat generated when the motor 22 works in the metal top cover 213 can be dissipated through the heat dissipation surface 2131, the first housing 211 and the second housing 212, thereby improving the heat dissipation efficiency of the pruner 100.
The metal top cover 213 includes an arch-shaped protrusion 2132, a recess 2133 provided around the arch-shaped protrusion 2132, and a mounting portion 2134 tilting from the side of the recess 2133 toward the main handle 11, the mounting portion 2134 being mounted to both the side portion 2112 and the second housing 212.

Of course, in other embodiments, the side portion 2112 and the second housing 212, the metal top cover 213 and the first housing 211 and the second housing 212 may be assembled and fixed by other methods, which is not limited herein.
The motor 22 is an external rotor motor, and includes an output shaft 221, an external rotor (not shown) sleeved on the output shaft 221, and a casing 222 sleeved on the external rotor and the outside of the output shaft 221. Because the motor 22 is an external rotor motor, that is, the external rotor is used to rotate to drive the motor 22 to operate and then drive the pruner 100 to operate, the external rotor cannot be too close to the casing 222, an avoiding gap (not shown) needs to be formed between the external rotor and the casing 222, and the avoiding gap can cause heat to be difficult to dissipate, so that the metal top cover 213 can enable heat to be rapidly dissipated, and the heat dissipation efficiency of the pruner 100 is improved.
The end of the output shaft 221 is provided with a fan 223, and the fan 223 is located at the bottom of the bottom shell 2111 to blow off the heat at the bottom of the housing assembly 21, thereby playing a role in cooling. Preferably, the fan 223 is installed in the power transmission assembly 23 to blow off heat generated when the power transmission assembly 23 is operated, thereby cooling the power transmission assembly 23.
The power transmission assembly 23 includes a bottom cover 231 installed at the bottom of the housing assembly 21, a first gear 232 and a second gear 233 installed at the bottom cover 231 and engaged with each other, at least two heat dissipation fins 234 are formed to extend from one side of the bottom cover 231 near the blade assembly 30, and a heat dissipation channel 235 is formed between the adjacent two heat dissipation fins 234.
The fan 223 is accommodated in the bottom cover 231, and a blast chamber 24 entirely covering the outside of the fan 223 and a heat dissipation channel 25 at the bottom of the blast chamber 24 and communicating with the outside are formed at one side of the bottom cover 231 away from the blade assembly 30. The fan 223 is connected to the output shaft 221 of the motor 22, the blower chamber 24 is enclosed by two heat dissipation fins 234 at the outermost side and is in a closed arrangement, the heat dissipation channel 25 is opened at an edge of the bottom cover 231 far away from the blade assembly 30, and in the width direction of the bottom cover 231, the heat dissipation channel 25 extends in a strip shape.
The bottom of the blast chamber 24 is also provided with a vent 26 communicating with the outside, and the vent 26 is also elongated in the length direction of the bottom cover 231. Therefore, when the motor shaft 221 rotates, the fan 223 can be driven to rotate, and when the fan 223 rotates, a low pressure area is generated nearby the fan 223, and at the moment, the ventilation opening 26 can supplement external cold air to the fan and discharge internal hot air through the heat dissipation channel 25, so that the heat dissipation effect is improved.
In the present invention, the heat dissipation channel 25 and the ventilation opening 26 are designed in a long shape and connect the blast chamber 24 and the outside in the thickness direction of the bottom cover 231 for the purpose of: the strip-shaped structure can increase the contact area between the cold/hot air and the corresponding ventilation opening 26/heat dissipation channel 25, so that the heat dissipation effect is better, but the invention is not limited thereto.
The bottom cover 231 includes a first bottom cover 2311 and a second bottom cover 2312 assembled and matched up and down, and a receiving cavity 2313 formed between the first bottom cover 2311 and the second bottom cover 2312, and the first gear 232 and the second gear 233 are received in the receiving cavity 2313. 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.
The two opposite ends of the second gear 233 are respectively provided with an eccentric wheel portion 2331, and the central axes of the two eccentric wheel portions 2331 do not overlap in the central axis direction of the second gear 233. The power transmission assembly 23 further comprises two crank rods 236 respectively sleeved on the two eccentric wheel portions 2331, one ends of the two crank rods 236 are sleeved on the corresponding eccentric wheel portions 2331, and the other ends of the two crank rods 236 are connected with the cutter bar assemblies 30, so that when the second gear 233 rotates, the crank rods 236 can be driven to move, and then the cutter bar assemblies 30 are driven to move back and forth to perform shearing operation. Preferably, the crank rod 236 has one end connected to the eccentric portion 2331 not overlapping in the center and the other end connected to the blade assembly 30 overlapping in the center, so that the effect of stably transmitting power can be achieved.
In the present invention, the assembly between the first and second bottom covers 2311 and 2312 is achieved by the mutual engagement of the screw 40 and the screw hole; 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. It will be appreciated that the rotational connection between the first gear 232 and the fan 223 and between the eccentric portion 2331 of the second gear 233 and the crank lever 236 is achieved by means of bearings 60, which are known in the art and will not be described in detail.
