Enter end and another 4th PIN 74 connects the current output terminal of the electric elements.
Movable piece 34 has first position and the second place, and it can live between the first position and the second place
It is matched with dynamicly on pedestal 32；Also, when movable piece 34 is movable between the first position and the second place, it can select one
Connect exchange PIN group 80 or direct current PIN group 70.
Specifically, when movable piece 34 is located at the first position, movable piece 34, which is connected, exchanges PIN group 80, two
One of them is electrically connected first PIN 81 with the realization of one of two the second PINs 82, and two the first PINs 81 are wherein
Wherein another realization of another and two the second PINs 82 electrically connects, so that the electric elements can access by the alternating current
In the alternating current circuit of source power supply, now, burnisher 100 can perform alternating current mode of operation.
When movable piece 34 is located at the second place, movable piece 34 connects direct current PIN group 70, two the 3rd PINs
73 one of them and two the 4th PINs 74 one of them realize and electrically connect that and two the 3rd PINs 73 are wherein another and two
Wherein another realization of 4th PIN 74 electrically connects, so that the electric elements can access the direct current powered by battery bag 20
Lu Zhong, now, burnisher 100 can perform direct current mode of operation.So, the burnisher 100 of the present embodiment, passes through switching
Switch 30 realizes the switching of alternating current-direct current, and the relay compared to prior art switches the structure of alternating current-direct current, greatly reduces product
Cost.
Further, movable piece 34 includes conductive mechanism, the conductive mechanism include being used for connecting exchange PIN group 80 or
If the dry contact of direct current PIN group 70.
When movable piece 34 connects exchange PIN group 80, between each 3rd PIN 73 and two the first PINs 81, often
Between individual 3rd PIN 73 and two the second PINs 82, between each 3rd PIN 73 and two the 4th PINs 74 and
The electric clearance between the contact in each 3rd PIN 73 and the access alternating current circuit is all higher than 4.8mm and climbs electricity
Distance is all higher than 8mm.So, when movable piece 34 connects exchange PIN group 80, due at least partly contact, two the
One the second PIN 82 of PIN 81, two and two the 4th PINs 74 access the alternating current circuit（With the AC power
Connection）, therefore by setting between the contact in each 3rd PIN 73 and the access alternating current circuit, each 3rd
Between PIN 73 and two the first PINs 81, between each 3rd PIN 73 and two the second PINs 82, each 3rd PIN
Electric clearance between pin 73 and two the 4th PINs 74 is all higher than 4.8mm and creep age distance is all higher than 8mm, can avoid the 3rd
PIN 73（It is connected with battery bag 20）Forceful electric power is carried because of electrical breakdown, when reduction operating personnel touch the inserted sheet of battery bag 20
The risk for injury of getting an electric shock, effectively strengthens protection effect.
Similar, when movable piece 34 connects direct current PIN group 70, each first PIN 81 and two the second PINs 82
Between, between each first PIN 81 and two the 3rd PINs 73, each first PIN 81 and two the 4th PINs 74 it
Between and each first PIN 81 and the access DC circuit in the contact between electric clearance be all higher than 4.8mm
And creep age distance is all higher than 8mm.So, when movable piece 34 connects direct current PIN group 70, due at least partly contact,
Two the second PINs, 82, two the 3rd PINs, 73, two the 4th PINs 74 access the DC circuit（With battery bag 20
Connection）, therefore by setting between the contact in each first PIN 81 and the access DC circuit, each first
Between PIN 81 and two the second PINs 82, each first PIN 81 and two the 3rd PINs 73, each first PIN 81
Electric clearance between two the 4th PINs 74 is all higher than 4.8mm and creep age distance is all higher than 8mm, can avoid the first PIN
81 are transferred to the DC circuit because of electrical breakdown and by forceful electric power, reduce got an electric shock when operating personnel touch the inserted sheet of battery bag 20 by
The risk of wound, effectively strengthens protection effect.
In addition, in the utility model, switching switch 30 is arranged in the accommodating chamber, only when cover lid 12 open it is described
During opening, switching switch 30 just can be operatively exposed to the opening, namely operating personnel can just enter to switching switch 30
Row operation；And when cover lid 12 closes the opening, switching 30 quilt cover lids 12 of switch cover.
Further, microswitch 40 is also included referring to Fig. 1, Fig. 3 to Fig. 5, the switching device, microswitch 40 is with cutting
Switch 30 is changed to be in series.Microswitch 40 has first state and the second state.Specifically, the first state is opening state
State, second state are closure state.In the present embodiment, when switching switch 30 can be operatively exposed to the opening
When, microswitch 40 is in the first state, and the DC circuit and/or the alternating current circuit disconnect all the time；When switching is opened
When closing 30 quilt cover lids 12 and covering and can not be operated, microswitch 40 switches to second state.So, can further improve
Safeguard protection.
Specifically, microswitch 40 includes the first switch portion 401 being located in the alternating current circuit and positioned at described straight
Second switch portion 402 on current circuit, first switch portion 402 and second switch portion 402 are arranged to synchronous and open and/or close.
So, when microswitch 40 is in the first state, first switch portion 402 makes the alternating current circuit disconnect all the time, and second
Switch portion 402 makes the DC circuit disconnect all the time.
Microswitch 40 includes trigger unit 41 and elastic component 42, and trigger unit 41 is movably set on housing 11, elastic component 42
It is engaged with trigger unit 41；Cover lid 12 includes the support division 50 coordinated with trigger unit 41.
When cover lid 12 closes the opening, the support division 50 supports trigger unit 41 and drives trigger unit 41 by initial bit
Put and move to trigger position, so that microswitch 40 switches to second state by the first state；When cover lid 12 is opened
During the opening, trigger unit 41 returns to the initial bit under the elastic restoring force effect of elastic component 42 by the trigger position
Put, so that the microswitch 40 switches to the first state by second state.So, when operating personnel's opening cover lid
12 with to battery bag 20 or switching switch 30 operate when, microswitch 40 is in the first state, can lifting operation when
Safeguard protection；On the other hand, when being in the first state due to microswitch 40, switching switch 30 is in electroless state
Lower to be operated, switching switch 30 does not have to go to examine certification as forceful electric power switch, without carrying out switch safety certification, saves certification
