Abstract

The utility model relates to an electric tool which comprises a main body, a power cord extending from the main body and a subsidiary power supply device connected with the power cord. The subsidiary power supply device includes at least one power supplier for providing power to other electric tools. Moreover, the subsidiary power device can uninterruptedly supply AC or DC currents to other electric tools of different types.

Description

Electric tool

Technical field

The utility model relates to a kind of electric tool, relates in particular to a kind of electric tool that can outputting power.

Background technology

The range of application of electric tool is quite extensive, mainly is to rely on power line to connect AC power power is provided and uses.But, limited by operating environment and scope, this type electric tool can only use in the extendible scope of its power line, for use has caused inconvenience.

At present, there has been the mode of utilizing the load cell bag to power to occur to address the above problem.What is more, the battery power of self can also be supplied with other electric tools uses, extended the scope of application of such instrument greatly, a kind of hay mover is disclosed as U.S. bulletin patent US 6484484, the housing of its hay mover is provided with a socket, and this socket connects the power brick of himself.By on this socket, connecting other electric tools, facilitate the use and the battery power in the power brick on this hay mover can be supplied with other electric tools that connect.

In addition, U.S. bulletin patent US 4870811 has also provided a solution, and it is provided with a socket equally on the fuel oil hay mover, by connecting other electric tools, and will be supplied to other electric tools uses by the electric energy that oil inflame transforms.

But, for scheme one, because the common power brick that adopts, the battery flying power of himself is limited, can't satisfy the instrument long-time application of (comprising hay mover self and connected other electric tools), the power brick that need more renew or this power brick carried out charging operations, thereby cause cost too high and use inconvenient.Self there are a lot of problems for scheme two, fuel oil type hay mover,, also do not advocate use as noise, environmental protection etc.

The utility model content

For overcoming the above-mentioned defective of prior art, the purpose of this utility model is: a kind of uninterruptedly electric tool of outputting power is provided, and simultaneously environmentally-friendly sanitary, noise are little, safe in utilization.

The purpose of this utility model is achieved in that a kind of electric tool, comprise main body and the power line that extends from main body, also comprise the auxiliary power supply that is connected on the power line, described auxiliary power supply comprises that at least one charger is to power to other electric tools.

As the improvement to the technical program: described charger can be AC socket; Described charger can be direct current jack and the rectifier transformer that is connected with direct current jack; Described charger can also comprise AC socket and direct current jack and the rectifier transformer that is connected with direct current jack; Also comprise circuit protection device on the described main body, it is one to be provided with the housing of opening, and is provided with mobile cover plate in opening and covers; An enterprising step of described mobile cover plate is provided with elastic mechanism to automatically reset; Described auxiliary power supply is installed in the corresponding described opening part in inside of circuit protection device.

Compared with prior art, the beneficial effects of the utility model are:

1) by being connected the auxiliary power supply on the power line, can provide continual electric energy to other electric tools, and, alternating current or direct current can be provided for dissimilar electric tools;

2) by circuit protection device, can grant asylum to control circuit and auxiliary power supply.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

See also Fig. 1 to Fig. 2, a kind of electric tool, in the present embodiment, especially refer to a kind of hay mover, comprise the main body 1 of electric tool and the power line 2 that extends from main body, wherein, described power line 2 one ends connect AC power, and the motor that the other end connects in the main body 1 by switch 21.After switch 21 triggered, described electric tool can normally use.

Described electric tool further comprises the auxiliary power supply 3 that is connected on the power line 2, in the present embodiment, it comprises that AC socket 4 reaches the rectifier transformer 52 that is connected with direct current jack with direct current jack 5, can be to other electric tools supply electric energy that are connected on the auxiliary power supply 3.Certainly, described auxiliary power supply 3 also can only have AC socket 4, perhaps the rectifier transformer 52 of direct current jack 5 and connection direct current jack.Because auxiliary power supply 3 is to be connected in parallel on the power line 2,, also can separately select to use so main body 1 can be used simultaneously with other electric tools that are connected.

See also Fig. 3 to Fig. 5, auxiliary power supply 3 also can be arranged on the handle part of electric tool, and extends power line 2, and it is normally used power line, can connect AC power.Certainly, can also be one section power line that plug receptacle is provided, connect AC power by connecting other power lines, perhaps, plug receptacle can also be located immediately at and connect power line on the main body 1 again, the effect of being reached is consistent.

Also be provided with circuit protection device 6 on the described power tool body, it is a housing, and inside accommodates control circuit and drenched with rain to prevent circuit.On described circuit protection device 6, be provided with opening 61, and cover by mobile cover plate 62; and mobile cover plate 62 also is connected with elastic mechanism 63, with the mobile cover plate 62 that automatically resets; in the present embodiment, elastic mechanism 63 is a spring, and the one end is fixedly connected on the housing.Corresponding described opening 61, auxiliary power supply 3 is arranged on the inside of circuit protection device 6.

In use, after pressing switch 21, motor is driven by the AC power that connects, and at this moment, can keep the operate as normal of electric tool; And when stopcock 21, the motor stall, described electric tool is in not duty.At this moment,, auxiliary power supply 3 is exposed and connect other electric tools thereon, then can provide electric energy, like this, just can keep the continual application of electric tool that connects by power line 2 if open mobile cover plate 62.If finish using, pull up the electric tool on the auxiliary power supply 3, the elastic mechanism 63 mobile cover plate 62 that can automatically reset covers also protection auxiliary power supply 3.Certainly, this is the two state that uses separately, and when they used jointly, the effect that is reached was identical.
