Specific embodiment

As illustrated, a kind of test pencil, including reference test bar 1, the upper end of described reference test bar 1 is fixed in insulator 10, electricity Resistance 3, neon tube 4, spring a5, spring lever 6, successively in insulator 10, are additionally provided with wire stripper in insulator 10, survey The top of one end that bar 1 is fixed in insulator 10 is provided with resistance 3, is provided with neon tube 4, on neon tube 4 above described resistance 3 Side is provided with spring a5, is provided with spring lever 6 above spring a5, and spring lever 6 is provided with screw 7, described screw 7 with absolutely Edge body 10 screw thread coordinates, and screw 7 presses closer spring lever 6, and rotating shaft 11 is fixed on insulator 10, and it is fixing that clamp handle 8 passes through rotating shaft 11 On insulator 10, the left and right sides of described insulator 10 is provided with the groove placing clamp handle 8, and clamp handle 8 has hand hay cutter mouth 9, two pincers Hand hay cutter mouth 9 on handle 8 is correspondingly arranged.

Described wire stripper includes briquetting 13, and briquetting 13 is arranged in the square hole 22 in insulator 10, square hole Draw ring 17 is symmetrically arranged with 22 two sides, the upper surface of briquetting 13 is higher than the upper surface of insulator 10, briquetting 13 lower end Be symmetrically arranged with two upper spring compressors 18, the bottom hole of square hole 22 be symmetrically arranged with two lower spring caps 19, upper spring compressor 18 with Lower spring cap 19 is correspondingly arranged, and is provided with spring b20 between upper spring compressor 18 and lower spring cap 19, and spring b20 upper end presses closer Spring compressor 18, spring b20 lower end presses closer lower spring cap 19, is symmetrically arranged with two blades 21 below briquetting 13, and blade 21 leads to Cross rotating shaft 14 to be hinged with briquetting 13, blade 21 is provided with hole b24, on the hole b24 on blade 21 and square hole 22 side wall Draw ring 17 is correspondingly arranged, and spring c16 one end connects draw ring 17, and the spring c16 other end is fixed in the b24 of hole, sets below blade 21 It is equipped with two symmetrical guide pads 23, the arcwall face being provided with arcwall face at side angle on guide pad 23 with the lower side angle of blade 21 connects Touch, insulator 10 is provided with hole a12, hole a12 is correspondingly arranged with the gap portion of two blades 21.
