Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The assembly structure schematic diagram of the auxiliary line-straining device that Fig. 1 provides for a kind of embodiment of the utility model.
Embodiment
Core of the present utility model is to provide a kind of auxiliary line-straining device, and this auxiliary line-straining device can reduce the operation easier of circuit terminal operation and improve its fail safe.
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, the assembly structure schematic diagram of the auxiliary line-straining device that Fig. 1 provides for a kind of embodiment of the utility model.
In embodiment, auxiliary line-straining device provided by the utility model, comprise main pipe 11, main pipe 11 is interior is axially movably fitted with the first action bars 12 along it, on anterior outer peripheral face of the main pipe 11, along its axial restraint, there is the outside of the second action bars 13, the second action bars 13 to have the 3rd action bars 14 along its axial restraint; The front end of the first action bars 12 is provided with the front end that front end with the first operation hook 121, the second action bars 13 of wire grip plug-in mounting adaptation is provided with the second operation hook 131, the three action bars 14 that match with wire grip and is provided with the support hook 141 matching with wire.In the course of work, by controlling the first action bars 12 moving axially along main pipe 11, make the first action bars 12 and the second action bars 13 cooperatively interact to realize the front end of wire grip is fixed and reclaimer operation by the first operation hook 121 and the second operation hook 131, thereby significantly improved operating personnel to wire can operating distance, and its operation easier is less, and operation process is simple and easy to do; Meanwhile, support hook 141 hangs on wire, thereby has effectively guaranteed structural reliability and the fail safe of described auxiliary line-straining device.
