Description
Technical field
It the utility model is related to test pencil technical field, more particularly to a kind of novel multi-use test pencil.
Background technology
Voltage test pencil is also test pencil, referred to as " electroprobe ".It is a kind of electrician tool, it is whether powered in electric wire for testing.Pen
There is a neon bulb in body, if neon bulb lights during test, illustrate that wire has electricity or the live wire for path, common test pencil can only be used
Carry out test circuit, staff is also needed to other instrument, inconvenient, therefore it is single how to solve test pencil function
Problem, it is that workmen is badly in need of solving.
Utility model content
The purpose of this utility model is to provide a kind of novel multi-use test pencil, to solve above-mentioned technical problem.
The utility model uses following technical scheme to achieve the above object：
A kind of novel multi-use test pencil, including electric installation and storage device are surveyed, the survey electric installation passes through storage device, institute
State survey electric installation to be made up of screw rod, current-limiting resistance, ammonia pipe and sheet metal, described screw rod one end opens up screw thread mouth, the other end and limit
Leakage resistance is in contact, and the current-limiting resistance is connected with ammonia pipe one end, the ammonia pipe other end series connection sheet metal, the storage device
It is made up of receiver, buckle, base and thread head, the receiver is plastic material, and upper lower casing is described by snapping connection
Current-limiting resistance is glued in receiver bottom surface and the base for placing thread head, the base are welded in ammonia pipe, the receiver bottom surface
Current-limiting resistance and ammonia pipe both sides are symmetrically mounted on, the thread head is threadedly coupled with screw thread mouth.
Preferably, the base quantity is ten, places different types of thread head, the thread head species has tack spiral shell
Line head, cross thread head, interior hexagonal screw thread are first-class.
Preferably, the base is hollow cylindrical structure, and base is threadedly coupled with thread head.
Compared with prior art, the utility model has advantages below：The utility model is simple in construction, reasonable in design, makes
Valency cost is low；During routine use, electroprobe is inserted into circuit, touches sheet metal with hand, ammonia pipe, which lights, then to be represented to be powered, and do not work then table
Show power-off, current-limiting resistance protection human body is endangered by high current, when needing the screwdriver of different model, can open storage
Box, the thread head needed is selected, can be used after replacing, and the thread head wide variety in receiver, meet routine use,
It is very convenient, preferably promote the use of.
Brief description of the drawings
Fig. 1 is this novel multi-use test pencil structure figure.
Fig. 2 is this novel multi-use test pencil receiver interior view.
In figure：1st, screw thread mouth, 2, screw rod, 3, buckle, 4, receiver, 5, sheet metal, 6, base, 7, ammonia pipe, 8, thread head,
9th, current-limiting resistance.
Embodiment
The utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of novel multi-use test pencil, including electric installation and storage device are surveyed, the survey electric installation passes through
Storage device, the survey electric installation are made up of screw rod 2, current-limiting resistance 9, ammonia pipe 7 and sheet metal 5, and described one end of screw rod 2 opens up spiral shell
Line mouth 1, the other end are in contact with current-limiting resistance 9, and the current-limiting resistance 9 is connected with the one end of ammonia pipe 7, the other end string of ammonia pipe 7
Join sheet metal 5, the storage device is made up of receiver 4, buckle 3, base 6 and thread head 8, and the receiver 4 is plastics material
Matter, whole clearing, upper lower casing are connected by buckle 3, and current-limiting resistance 9 and ammonia pipe 7, the receipts are glued in the bottom surface of receiver 4
The base 6 for placing thread head 8 is welded in the bottom surface of case 4, and the base 6 is symmetrically mounted on current-limiting resistance 9 and the both sides of ammonia pipe 7,
The thread head 8 is threadedly coupled with screw thread mouth 1.
The quantity of base 6 is ten, places different types of thread head 8, the species of thread head 8 has tack thread head
8, cross thread head 8, interior hexagonal thread head 8 etc..The base 6 is hollow cylindrical structure, and base 6 is threadedly coupled with thread head 8.
During routine use, electroprobe is inserted into circuit, touches sheet metal 5 with hand, ammonia pipe 7, which lights, then to be represented to be powered, and is not worked then
Power-off is represented, current-limiting resistance 9 is protected human body to be endangered by high current, when needing the screwdriver of different model, can opened
Receiver 4, the thread head 8 needed is selected, can be used after replacing, and the wide variety of thread head 8 in receiver 4, meet
Routine use, it is very convenient.
Described above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With new teaching, in the case where not departing from principle of the present utility model and spirit, the change that is carried out to embodiment, repair
Change, replace and modification is still fallen within the scope of protection of the utility model.
