Accompanying drawing explanation
Accompanying drawing 1 is the overall schematic of electric tool of the present invention;
Accompanying drawing 2 is the power supply circuit of laser instrument in electric tool of the present invention.
In accompanying drawing:
1-body, 2-laser instrument, 3-subunit switch, 4-laser switch, 5-linked switch.
Detailed description of the invention
Below in conjunction with accompanying drawing being preferred embodiment described in detail to Multi-head electric tool of the present invention.
Accompanying drawing 1 is the overall schematic of electric tool of the present invention; here electric tool is for electric circular saw; it comprises body 1; body 1 is provided with laser instrument 2; wherein body 1 has duty and stopped status; laser instrument 2 has luminance and OFF state; body 1 and laser instrument 2 are to provide electric energy by different power supply circuits; both can be direct current for providing the power supply of electric energy; also can be exchange; can be powered respectively to the two by multiple power supply, also can power etc. to the two by the mode that a power supply is in parallel.
Accompanying drawing 2 is the circuit diagram of electric tool of the present invention, as shown in the figure, body 1 is provided with subunit switch 3, for controlling work and the shutdown of body 1, normally be located on the power supply circuits of body 1, during subunit switch 3 path, body 1 is in running order, during subunit switch 3 open circuit, body 1 is in stopped status, meanwhile, preferably, subunit switch 3 is provided with back-moving spring, after pressing subunit switch 3, body is started working, when loosing one's grip, subunit switch 3 can automatically reset to stopped status, facilitates the operation of user; The power supply circuits of laser instrument 2 are provided with laser switch 4 and linked switch 5, these two switches are all used to the break-make of control circuit, all there is channel status and off state, when being all in channel status both and if only if, laser instrument 2 just can be luminous, other situation laser instruments 2 are in OFF state without exception, therefore in order to realize this object, the two are connected on the main line of the power supply circuits of laser instrument 2 in the present embodiment.
For linked switch 5, can synchronism switching between itself and subunit switch 3, specific in the present embodiment, when subunit switch 3 is in channel status, when also namely body 1 is started working, linked switch 5 synchronism switching is to channel status; When subunit switch 3 is in off state, when also namely body 1 is shut down, linked switch 5 synchronism switching is to off state.The design of this interlock, can prevent from forgetting that the situation of closing laser instrument 2 occurs well.
When user does not use electric tool, all switches are all in off state, and body 1 is shut down.First laser switch 4 is switched to channel status subsequently, now because linked switch 5 is still in off state, therefore laser instrument 2 still extinguishes; Next press subunit switch 3 and make its path, body 1 is started working, and linked switch 5 is subject to the driving of subunit switch 3 simultaneously, also channel status is switched to, now laser instrument 2 is luminous, and user can carry out calibration location with laser, and uses electric tool to carry out the work such as the cutting of workpiece; When after end-of-job, unclamp subunit switch 3, it automatically resets to off state, drives linked switch 5 also to switch to off state simultaneously, and the power supply circuits of laser instrument 2 disconnect, and it switches to OFF state from luminance.Like this, although user does not contact laser switch 4 after a procedure again, laser instrument 2 also quits work, and serves the effect preventing waste of energy, if at this moment need to reuse laser instrument 2, only need directly press subunit switch 3.But, when the electric tool long-term not used time, still need laser switch 4 to switch to off state, be conducive to the service time of prolongation instrument.
