Abstract
The invention discloses a universal meter convenient to use. The universal meter convenient to use comprises a universal meter body, a positive pole jack, a negative pole jack, test lines and a meter stylus. The test lines comprise the red positive pole test line and the black negative pole test line, one end of the meter stylus is fixed on the positive pole test line and the negative pole test line, the universal meter body is provided with an inwards concave cylindrical groove, and a fixed supporting rod is arranged in the groove. The fixed supporting rod is sleeved with a round roll which is further provided with a spring, the other end of the spring is fixed on the fixed supporting rod, the positive pole jack and the negative pole jack of the universal meter body are arranged on the surface of the round roll, and the round roll rotates on the fixed supporting rod in a reciprocating mode through the spring. The universal meter convenient to use is simple in structure and convenient and rapid to use, and is directly and fixedly arranged, so the universal meter convenient to use is prevented from being mounted and dismounted every time the universal meter is used, and meanwhile the situation that the test lines fall off and are lost is avoided.
Description
Technical field
The present invention relates to instrument and equipment, be specifically related to a kind of multimeter easy to use.
Background technology
Multimeter is also called multi-meter, multimeter, avometer, numerous table etc., is the indispensable measurement instrument of the departments such as power electronics, generally with measuring voltage, electric current and resistance for fundamental purpose.Multimeter is divided into pointer multimeter and digital multimeter by display mode.It is a kind of multi-functional, multiple range measurement instrument, general multimeter can measure DC current, DC voltage, alternating current, alternating voltage, resistance and audio-frequency electric equality, some parameters (as β) etc. can also surveying alternating current, electric capacity, inductance value and semiconductor had.
By a multimeter, multimeter conventional in prior art adds that two external p-wires form mostly, in use, being taken out by p-wire is inserted in the both positive and negative polarity jack of multimeter, extract again after finishing using and put well respectively, this type of multimeter uses relatively trouble, and p-wire plug easily damages, and during storage as easy as rolling off a log go out the situation of active, increase unnecessary trouble to follow-up use, result of use is not good enough.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, convenient to use, adopt and be directly fixedly installed, avoid each installation and removal used, eliminate the multimeter easy to use of situation that p-wire drops and loses simultaneously.
Technical scheme of the present invention is, a kind of multimeter easy to use, described multimeter easy to use comprises multimeter, positive pole jack, negative pole jack, p-wire and test pencil, described p-wire comprises red positive pole p-wire and the negative pole p-wire of black, one end of described test pencil is separately fixed on positive pole p-wire and negative pole p-wire, described multimeter is provided with the cylindrical groove of an indent, a fixing pole is provided with in described groove, described fixing pole is equipped with a circular-roll, described circular-roll is also provided with a spring, the other end of described spring is fixed on fixing pole, the positive pole jack of described multimeter and negative pole jack are arranged on the surface of described circular-roll, the other end of described positive pole p-wire and negative pole p-wire is corresponding to be respectively arranged in positive pole jack on described circular-roll and negative pole jack, described circular-roll does round rotary motion by spring on described fixing pole.
In a preferred embodiment of the present invention, effective tensile elongation of described positive pole p-wire and negative pole p-wire is 30cm.
In a preferred embodiment of the present invention, described multimeter is respectively arranged with two perforates in the below of described circular-roll, and described positive pole p-wire and negative pole p-wire are each passed through two perforates.
Of the present invention is a kind of multimeter easy to use, and structure of the present invention is simple, convenient to use, adopts and is directly fixedly installed, and avoids each installation and removal used, eliminates the situation that p-wire drops and loses simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of multimeter easy to use in a preferred embodiment of the present invention.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Of the present invention is a kind of multimeter easy to use, shown in Figure 1, described multimeter easy to use comprises multimeter 1, positive pole jack 2, negative pole jack 3, p-wire and test pencil 4, described p-wire comprises red positive pole p-wire 5 and the negative pole p-wire 6 of black, and one end of described test pencil 4 to be separately fixed on positive pole p-wire 5 and negative pole p-wire 6.
Described multimeter 1 is provided with the cylindrical groove of an indent, a fixing pole 7 is provided with in described groove, described fixing pole 7 is equipped with a circular-roll 8, described circular-roll 8 is also provided with a spring 9, the other end of described spring 9 is fixed on fixing pole 7.
The positive pole jack 2 of described multimeter 1 and negative pole jack 3 are arranged on the surface of described circular-roll 8, and the other end of described positive pole p-wire 5 and negative pole p-wire 6 is corresponding to be respectively arranged in positive pole jack 2 on described circular-roll 8 and negative pole jack 3.
Described circular-roll 8 does round rotary motion by spring 9 on described fixing pole 7.
Further, effective tensile elongation of described positive pole p-wire 5 and negative pole p-wire 6 is 30cm.
Further, described multimeter 1 is respectively arranged with two perforates in the below of described circular-roll 8, and described positive pole p-wire 5 and negative pole p-wire 6 are each passed through two perforates.
Multimeter easy to use of the present invention in use, directly can haul test pencil 4 positive pole p-wire 5 and negative pole p-wire 6 are directly pulled out from perforate, now circular-roll 8 rotates, positive pole p-wire 5 and negative pole p-wire 6 are elongated, use when being convenient to test, after finishing using, decontrol test pencil 4, now circular-roll 8 under the effect of spring 9 again rolling on circular-roll.
Of the present invention is a kind of multimeter easy to use, and structure of the present invention is simple, convenient to use, adopts and is directly fixedly installed, and avoids each installation and removal used, eliminates the situation that p-wire drops and loses simultaneously.
The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
