Abstract
The utility model discloses a multipurpose duplex tube safety electricity tester, comprising a probe rod, a transparent pen holder, a resistor, neon tubes, a spring, a pen clamp, etc. The utility model adopts two neon tubes, and the probe rod has multi-purpose and multifunction. The utility model has the advantages of high safety and reliability, simple structure, easy fabrication, obvious effect, less investment and salability.
Description
The utility model relates to a kind of electrician's instrument.
Present employed electroscope or electroscope, its probe is an in-line, meet the just inconvenience use of criss-cross screw on occasion, in penholder hollow, a neon tube only is housed, very dangerous during use, do not know any reason and damage that see during use that neon tube does not work just to think not have electricity by mistake, the result causes human casualty accident or damages machinery and equipment owing to neon tube.
The purpose of this utility model is to avoid weak point in the above-mentioned prior art and provides a kind of, and feeler lever can be dismantled, and a neon tube damages, and the another neon tube still can be shinny, and have many usefulness, and safer electroscope.
The purpose of this utility model can reach by following measure: feeler lever is dismountable, and an end is in-line, and the other end is a cruciform; The neon tube of two parallel connections is housed in transparent penholder is hollow.
Feeler lever of the present utility model is provided with the boss of symmetry, when feeler lever inserts in the metal screw, boss is embedded in the breach of screw rod, is fixed together by nut; One end of metal screw contacts with resistance.Feeler lever also can dress up with transparent pen arm be one.
Advantage of the present utility model is: feeler lever is dismountable and an end is a cruciform, and the other end is an in-line, has multi-functionally, and safeguard protection is reliable, and is simple in structure, easily manufactured, invests little instant effect, and in demand, benefit is high.
The drawing of accompanying drawing is described as follows:
Fig. 1: be the utility model synoptic diagram.
Fig. 2: feeler lever is fixing synoptic diagram.
The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment:
As shown in Figure 1: feeler lever 1 is dismountable, and an end is in-line, and the other end is a cruciform.Just can work as Flathead screwdriver and use, turn around and also can work as the Philips screwdriver use, can a bar dual-purpose, more convenient.In transparent pen arm 5 hollow, two neon tubes 8 are equipped with in parallel connection, even one of them neon tube burns out, another neon tube also can be bright, can avoid having only a neon tube to burn out, and misidentification does not have electricity and causes personal injury.Feeler lever 1 is provided with the boss 2 of symmetry, when feeler lever 1 inserts in the metal screw 4, boss 2 is embedded in the breach of screw rods 4, and by nut 3 it is tightened together; One end of metal screw 4 contacts with resistance 6, and when the test electricity, hand is arrested pen clip 10 can form path.
Shown in Figure 2, be the another kind of embodiment of the utility model, feeler lever 1 can be fixed on the transparent pen arm 5.
Claims (3)
1, a kind of many with two-tube safe electroscope, form by feeler lever 1, transparent pen arm 5, resistance 6,7, neon tube 8, spring 9, pen clip 10 etc., it is characterized in that: feeler lever 1 is dismountable, and an end is in-line, the other end is a cruciform; In transparent pen arm 5 hollow, two neon tubes 8 are equipped with in parallel connection.
2, according to claim 1 many with two-tube safe electroscope, it is characterized in that: feeler lever 1 also can be dressed up fixing.
3, according to claim 1 many with two-tube safe electroscope, it is characterized in that: feeler lever 1 is provided with the boss 2 of symmetry, and feeler lever 1 inserts in the metal screw 4, and makes in the breach of boss 2 embedding screw rods 4, by nut 3 it is tightened together; One end of metal screw 4 contacts with resistance 6.
