It should be noted that used term is only to describe detailed description of the invention here, and be not intended to the illustrative embodiments of restricted root according to the application.As used herein, unless the context clearly indicates otherwise, otherwise singulative is also intended to comprise plural form, in addition, it is to be further understood that, " comprise " when using term in this manual and/or " comprising " time, it indicates existing characteristics, step, operation, device, assembly and/or their combination.
It should be noted that, term " first ", " second " etc. in the description of the application and claims and above-mentioned accompanying drawing are for distinguishing similar object, and need not be used for describing specific order or precedence.Should be appreciated that the data used like this can be exchanged in the appropriate case, so as the embodiment example of the application described herein if with except here diagram or describe those except order implement.In addition, term " comprises " and " having " and their any distortion, intention is to cover not exclusive comprising, such as, contain those steps or unit that the process of series of steps or unit, method, system, product or equipment is not necessarily limited to clearly list, but can comprise clearly do not list or for intrinsic other step of these processes, method, product or equipment or unit.
For convenience of description, here can usage space relative terms, as " ... on ", " in ... top ", " at ... upper surface ", " above " etc., be used for the spatial relation described as a device shown in the figure or feature and other devices or feature.Should be understood that, space relative terms is intended to comprise the different azimuth in use or operation except the described in the drawings orientation of device.Such as, " in other devices or structure below " or " under other devices or structure " will be positioned as after if the device in accompanying drawing is squeezed, being then described as the device of " above other devices or structure " or " on other devices or structure ".Thus, exemplary term " in ... top " can comprise " in ... top " and " in ... below " two kinds of orientation.This device also can other different modes position rotating 90 degree or be in other orientation, and relatively describe space used here and make respective explanations.
As shown in Figure 1, an Insulation spanner of embodiment comprises working head 10 and handle, and working head 10 is connected with handle, the outer surface of handle is provided with insulation sleeve 20.
The technical scheme of application the present embodiment, insulation sleeve 20 can prevent when using spanner to carry out hot line job, causes electric shock accidents because of spanner conduction.Therefore, the present embodiment can solve the problem that spanner contact limbs cause injury of getting an electric shock effectively.
As shown in Figure 1, in the technical scheme of the present embodiment, working head 10 comprises active chuck.The active chuck of working head 10 has two parallel clamping faces, the distance between turn guiding mechanism and adjustable two working faces.Active chuck structure is mainly used to install or dismounting outer-hexagonal bolt, nut.Because working head 10 is active chuck, therefore can the bolt of corresponding different model or nut.
In unshowned in the drawings embodiment, the structure of working head 10 is not limited to active chuck, and can determine the concrete structure of working head 10 according to the kind installing or dismantle part, concrete scheme needs to determine according to real work.
As shown in Figure 1, in the technical scheme of the present embodiment, insulation sleeve 20 wraps up handle completely.Insulation sleeve 20 wraps up handle completely farthest can cover current-carrying part in Insulation spanner, reduces the danger causing electric shock when using Insulation spanner to carry out hot line job.
In unshowned in the drawings embodiment, insulation sleeve 20 surface also has anti-skid structure.The anti-skid structure of insulating barrier can prevent workman's Insulation spanner slippage when operating, and avoids causing security incident.Certainly, the manufacture craft of anti-skid structure does not have particular requirement, can adopt rough surface technique or other slide-resistances, concrete structure according to actual needs and concrete technology determine.
As shown in Figure 1, in the technical scheme of the present embodiment, one end of handle is provided with working head 10.The quantity of working head does not have particular/special requirement, can determine according to actual needs.
In the technical scheme of the present embodiment, working head 10 has electrodeposited coating.Adopt the effect of electrodeposited coating as follows at working head 10:
