Abstract
The utility model provides a plug used for an electric tool, which comprises a plug body and a power supply connection wire, wherein the power supply connection wire is connected with the plug body into a whole body, the plug also comprises an elastic device, and both ends of the elastic device are respectively connected with the power supply connection wire. The power supply connection wire has better flexibility, and when the length of the electric tool needs to be adjusted, the elastic device can generate a stretched length so as to make the electric tool used more conveniently; simultaneously, conductor copper wire breakage caused by the conventional cord straight contraction is avoided, the safety of the plug is increased, and the contraction of the elastic device can greatly prolong the service life of a plug machine; and in addition, when the working range of the electric tool exceeds the length of the power supply connection wire, the elastic device can generate a response force to prompt an operator to avoid pulling out the plug body, so the use is more convenient.
Description
Technical field
The utility model relates to a kind of plug, relates in particular to a kind of plug that is used for electric tool.
Background technology
At present, tradition is used for the plug on the electric tool (as grass-mowing machine, hay mover etc.), comprises header body, electric power connection line, wherein, described electric power connection line is a straight line, usually the electric power connection line of this structure is that thermoplastic macromolecule material is made, and its retractility is relatively poor.Running into when needing regulating handle to prolong to beat the grass or mow radius, traditional solution is to reserve the electric wire of certain-length in advance on the take-up reel of electric tool (grass-mowing machine, hay mover etc.), so that the usefulness of elongation, and long-term straight shape is flexible, the retractility of electric power connection line is reduced greatly, cause the electric power connection line fracture, thereby shortened the useful life of electric power connection line, and electric power connection line can be too high because of frequency of usage, and cause the fracture of inner conductor (copper wire), accidents caused, thus the fail safe of plug reduced.
The utility model content
Technical problem to be solved in the utility model provides that a kind of telescopicing performance is good, long service life, the plug that is used for electric tool safe in utilization and simple in structure.
In order to solve the problems of the technologies described above, a kind of plug that is used for electric tool of the utility model comprises header body, electric power connection line, described electric power connection line and described header body link into an integrated entity, wherein, also comprise elastic device, described elastic device two ends link to each other with electric power connection line respectively.
Above-mentioned a kind of plug that is used for electric tool, wherein, described elastic device is a spirality elastic force flexible cord, described spirality elastic force flexible cord two ends link to each other with described electric power connection line.
The utlity model has following advantage:
Owing to be provided with an elastic device in the middle of the described electric power connection line, electric power connection line has had telescopicing performance preferably, when needs are regulated electric tool length, elastic device can produce a spread length, make that electric tool is convenient to be used, simultaneously, avoided shrinking the conductor copper wire fracture that causes because of the straight shape of traditional flexible cord, improved the fail safe of plug, and the contraction of elastic device will strengthen the useful life of plug machinery greatly; In addition, when the working range of electric tool exceeded electric power connection line length, elastic device can produce a response, and prompting operation person avoids header body to be pulled out, thereby was more convenient for using; In addition, because described elastic device is a spirality elastic force flexible cord, production cost is lower, and relatively simple for structure.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, in order to solve the problems of the technologies described above, a kind of plug that is used for electric tool of the utility model, comprise header body 1, electric power connection line 2, described electric power connection line 2 links into an integrated entity with described header body 1, also comprise elastic device, described elastic device 3 is arranged in the middle of the electric power connection line 2, and elastic device 3 two ends link to each other with electric power connection line 2 respectively.Owing to be provided with an elastic device 3 in the middle of the described electric power connection line 2, electric power connection line 2 has had telescopicing performance preferably, when needs are regulated electric tool length, elastic device 3 can produce a spread length, make that electric tool is convenient to be used, simultaneously, avoided shrinking the conductor copper wire fracture that causes because of the straight shape of traditional flexible cord, improved the fail safe of plug, and the contraction of elastic device 3 will strengthen the useful life of plug machinery greatly; In addition, when the working range of electric tool exceeded electric power connection line length, elastic device 3 can produce a response, and prompting operation person avoids header body to be pulled out, thereby is more convenient for using.
Elastic device is unrestricted, in order to save cost, be example with spirality elastic force flexible cord as elastic device 3 in the present embodiment, described spirality elastic force flexible cord two ends link to each other with described electric power connection line 2, spirality elastic force flexible cord is passed through around rod by thermoplastic macromolecule material, baking molding and making, make helical spring line magnification more than 1: 8, make the product of equal length have great extendable room, make the use of electric tool more handy, act freely, reduced simultaneously because of the straight shape of traditional flexible cord is shunk the conductor copper wire that causes and ruptured, it is safer that plug is used, and because described elastic device 3 is a spirality elastic force flexible cord, therefore, production cost is lower, and relatively simple for structure.
In sum, the utility model is compared with traditional plug that is used for electric tool, has that telescopicing performance is good, a long service life, with low cost, safe in utilization and advantage of simple structure.
The utility model is not limited to the scope that the foregoing description is described, and the technical scheme that the means that all employing equivalences are replaced obtain is all in the scope of the utility model protection.
