Embodiment 3
As shown in Fig. 8 to Fig. 6, on the basis of embodiment 1, to be easily installed first motor 21, the second motor 22, transmission
Mechanism and power head 71,72,73 are additionally provided with supporting mechanism, and first motor 21 and the second motor 22 are mounted on supporting mechanism,
Power head 71,72,73 is mounted on supporting mechanism front.
Wherein, power head 71 on supporting mechanism, 72,73, first motor 21, the second motor 22 and transmission mechanism are integrated in
Main part, form a module；It is first integrated into the mode that modular construction assembles again, ensure that the orderly of each components
Installation is scattered or in disorder, convenient for the integral arrangement of apparatus structure after avoiding loading shell.
As shown in fig. 6, power head includes line shaft 701 and the flat head 702 positioned at 701 front end of line shaft, line shaft
701 are connected to motor, and flat torque drive portion 702 is for transmitting torque.
Wherein, supporting mechanism includes the first support 5 and second support 4 that front and back is arranged, first support 5 and second support 4
Between the modes such as clamping, grafting, screw connection or welding can be used connect, first support 5 and second support 4 are corresponding offer before
Three pairs of mounting holes 44 afterwards, each power head are rotatably installed in corresponding a pair of of front and back mounting holes 44 by bearing 74, second support 4
On offer supported hole 45 for installing first motor 21 and the second motor 22, first motor 21 and 22 rear portion of the second motor peace
In corresponding supported hole 45, front end is connect with power head 71,73.
The rounded structure of first support 5, three mounting holes 44 are disposed side by side in the first support 5, in the first support 5
It is additionally provided with stitch interface mounting hole 51, second support 4 includes the front support seat 41 and rear support 43 of the rounded structure of gabarit
And it is connected to the support frame 42 between front support seat 41 and rear support 43, supported hole 45 is disposed side by side on rear support 43
On, so that first motor 21 and the second motor 22 are arranged side by side.First support 5, front support seat 41 and rear support 43 are circle
Structure and hull shape adapt to, and are easily installed cooperation.
The power of first motor 21 and the second motor 22 is directly passed to power head 71,73 after the deceleration of deceleration mechanism.The
The power of three motors 31 by bevel gear pair is transferred to transmission shaft 61 after the deceleration of deceleration mechanism, then through driving gear 64 and driven
Gear 65 passes to power head 72.
In this example, three power heads are arranged side by side, and the corresponding power head 72 of third motor 31 is located at first motor 21 and the
Between corresponding two power heads 71,73 of two motor 22.
Further, to prevent rotation of the supporting mechanism in body 11, spline structure is provided on supporting mechanism, in this example
Spline structure is that the limiting slot 47 being arranged on support frame 42, limiting slot 47 and shell or other components cooperate, in support machine
Structure limits rotation after being packed into shell, convenient for circumferentially positioned after loading.
Preferably, body 11 and handle 12 are integrally formed, body 11, handle 12, power head 71,72,73, first
Frame 5, second support 4 and transmission mechanism are made of metal.These structures are each made of a metal, and make handle 12 after taking out battery 8
It is able to carry out integral high-temperature sterilizing, overcoming handle 12 in the prior art cannot integrally sterilize, and be individually replaced every time using needs
The problem of sterilizing shell, reduce use cost.
The present invention compared with the existing technology the advantages of be:
1, power unit is optimized, power unit is separately positioned in body and handle, so that each motor has foot
Enough installation spaces avoid multiple motors from clustering round together, and structure is complicated, and installation is inconvenient.On the one hand arragement construction is simplified, electricity
Machine is easy to operate when installing, and utilizes enclosure interior space rationally；Another aspect motor heat dissipation effect arranged apart obtains
It improves.
2, installation position is provided by second support, to install first motor, the second motor and transmission mechanism etc., passes through second
Frame realizes the support and positioning of multiple components, ensure that installation accuracy, and be convenient for modularization management.
3, first support, second support, transmission mechanism and shell are each made of a metal, and power handle is enable to take in battery
Integral high-temperature sterilizing is realized after out, does not have to reduce use cost using a sterilizing shell is all consumed every time.
Any person skilled in the art all without departing from the spirit and scope of the present invention, carries out above-described embodiment
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from disclosed spirit with
All equivalent modifications completed under technical idea or change should be covered by the claims of the present invention.
