Problems solved by technology

[0002] Because the existing electric test pen does not have its own lighting device, it is very inconvenient for users to use it in dark places. Although there can be auxiliary lighting tools such as flashlights, it is often necessary to hold the flashlight in the left hand, and the electric test pen in the right hand. Occupied, unable to assist the right hand to do some maintenance movements
In addition, if there is a circuit failure in an ordinary residential building at night, a flashlight is used for auxiliary lighting during maintenance, and it is often necessary to stand on a ladder. If both hands are occupied, the body cannot maintain balance and there is a danger of falling.
[0003] And in the prior art, it is usually that the electric test terminal is set as a screwdriver bit, but the current general-purpose screw heads are mainly two styles of slotted and cross-slotted, which causes the screwdriver bit set by the electric test pen to be different. May be universal

Abstract

The invention provides a test pencil which comprises lighting devices, a test pencil point and a test pencil rod. The lighting devices are clamped on the test pencil point through a clamp, the irradiation direction of the lighting devices is consistent with the direction of the test pencil point, and the test pencil point is detachably connected with the test pencil rod. A slotted-point or cross-recess screwdriver bit is adopted in the test pencil point. The test pencil has the advantages that a small type flashlight is clamped on the test pencil point, and therefore the left hand can be free to assist the right hand in completing the overhauling motion or the left hand is used for assisting in balancing. Meanwhile, light can be prevented from being blocked by the test pencil, shadowless lighting is achieved, the structure is simple, and use is convenient; in addition, the lighting devices and the test pencil can be disassembled, and therefore whether the lighting devices are damaged or the test pencil is damaged, the lighting devices or the test pencil can be independently replaced; the test pencil point is detachably connected with the test pencil rod, and therefore the screwdriver bit arranged on the test pencil can perform replacement according to needs of a user.
