Problems solved by technology

However, the traditional continuity test pen is composed of the test pen body, wires, and test rods connected in sequence. Open, waste time and energy, and the entangled wires will be squeezed and bent, which will easily cause hard damage to the inner core wire of the wire, resulting in open circuit or poor contact of the inner core wire of the wire, affecting the detection effect of the test pen

Embodiment Construction

[0008] The present invention will be further described below in conjunction with accompanying drawing.

[0009] see figure 1 , the anti-winding on-off test pen of the present invention includes a test pen holder 1, a test head 2, a light-emitting diode 3 and a wire 4, the tail end of the pen holder 1 is provided with a groove 6 around the outer wall, and the outer wall of the pen holder 1 is close to the groove. A protruding pen lug 7 is provided at the groove 6, and an alligator clip 5 is connected to the terminal of the wire 4, and an insulating sheath is provided on the outside of the alligator clip 5.

[0010] When in use, the test head 2 on the test pen holder 1 and the alligator clip 5 at the end of the wire 4 can be used to test and judge the continuity of the circuit; Fixed on the pen ear 7, like this, the wire 4 of the on-off test pen is not easy to be entangled together, and the internal core wire of the wire 4 will not be damaged due to being squeezed, and the oper...

Abstract

The invention discloses an anti-winding on-off test pen, which comprises a test penholder, a test head, a light-emitting diode and a lead, wherein the tail end of the penholder is provided with a groove around the outer wall; the outer wall of the penholder close to the groove is provided with a raised pen lug; and the terminal of the lead is connected with a crocodile clip. The on-off test pen has a simple structure and is convenient to use, the lead is not easily wound together during take-up and release, and damage of the internal core wire of the lead is not caused by extrusion.

Description

technical field [0001] The invention relates to an electronic measuring tool, in particular to an anti-winding on-off testing pen. Background technique [0002] At present, in the installation and maintenance process of various lines of electric power, electronics, communication, etc., people often use the on-off test pen to judge the on-off state of the wire. However, the traditional continuity test pen is composed of the test pen body, wires, and test rods connected in sequence. Opening, wasting time and energy, and the entangled wires are squeezed to form a bend, which is easy to cause hard damage to the inner core wire of the wire, resulting in open circuit or poor contact of the inner core wire of the wire, which affects the detection effect of the test pen. Contents of the invention [0003] The object of the present invention is to provide an anti-tangle on-off testing pen, which can effectively solve the above problems. [0004] In order to achieve the above obje...
