This low pruner for being conducive to heat dissipation.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of pruner conducive to heat dissipation, packet
Casing, motor, blade assembly with accommodating chamber are included, the output end of motor is connect by transmission component with blade assembly, described
Blade assembly is contained in gear-box, and the handle lower end of the casing is releasably connected with the battery powered to the motor
Packet, it is characterised in that: the gear-box is equipped with the first heat release hole inside and outside connection gear-box, and casing is equipped with connection accommodating chamber
With the second extraneous heat release hole, the interior heat generated of gear-box sheds via the first heat release hole, the second heat release hole to the external world.
For the ease of connection the first heat release hole, the second heat release hole will be equipped with outside heat loss to casing, in the accommodating chamber
Heat dissipation channel.
In order to radiate faster, second heat release hole is positioned close to the side of the first heat release hole.
In order to lengthen cruise duration and control panel and plug arrangement are reasonable, the handle lower, transverse of the casing is equipped with control
Making sheet, the handle lower part of casing are equipped with groove, 2 plugs stretched out outside casing are integrated on control panel, and plug is contained in
In the groove, correspondingly, the battery pack has 2, each battery pack is equipped with and corresponding plug inserting connection
Socket.
In order to facilitate battery pack dismounting, one of the casing or the battery pack is equipped with sliding slot, and another is equipped with
With the gib block of sliding slot cooperation.
It the cross section of sliding slot can be there are many shape, it is preferable that the cross section of the sliding slot is L-shaped.In this way convenient for molding
Production.
In order to more in good order, the sliding slot on casing is set or gib block is located in the groove.In this way, battery pack is torn open
After unloading, sliding slot or gib block on casing do not seem lofty, and monnolithic case compares coordination.
In order to rationally utilize space, so that plug and battery pack are in good order, 2 plugs are laterally arranged in the control
Making sheet bottom, correspondingly, 2 battery packs are also laterally arranged in the control panel bottom.General control board bottom portion laterally away from
From bigger, lateral setting plug and battery pack, the space of control panel bottom can be rationally utilized.
Compared with the prior art, the advantages of the utility model are: by the first heat release hole of setting and the second heat release hole, just
Radiate in gear-box, such gear-box can adopt it is made of plastic, compared to the prior art, gear-box using thermal conductivity it is preferable
Metal be made, the utility model cost is lower；In addition, being radiated by blast wheel to gear-box compared to existing, this is practical new
Type structure is simple, does not account for additional space.
