Abstract
The utility model discloses a kind of test pencil of improvement, solve existing test pencil and there is use inconvenience and flimsy problem.The penholder that the utility model comprises test nib and is connected with this test nib, is also comprised the lighting device removably connected by " Ω " type elastic clip and penholder, is arranged on the arm clamping device of pen arm end, and is enclosed within the gum cover at penholder two ends; The direction of illumination of described lighting device is consistent with the written direction of test.The utility model is reasonable in design, significantly optimizes the usability of test pencil, and effectively extends its serviceable life.
Description
Technical field
The utility model relates to a kind of test pencil of improvement.
Background technology
Whether test pencil is also test pencil, and being called for short " electroprobe ", is a kind of electrician tool, be used in test wires charged, be requisite measurement apparatus during electrician operates, be usually used in the occasions such as security protection construction, interior decoration.There is a neon bulb in its handwriting, if neon bulb is luminous during test, illustrates that wire has electricity, or be the live wire of path.
At present, the most structure of test pencil is on the market simple, and in use all there is awkward defect, this kind of defect generally shows following two aspects:
(1) phenomenon that often can come off in use procedure, falls and damages or need again to pick up, and uses comparatively inconvenience.And because penholder is normally made up of hard transparent plastic, material is more crisp, easily causes penholder parts against wear because of clashing into when thus accidentally dropping, causing the neon bulb inside it to damage.
(2) test pencil does not have self illumination device, is difficult to be suitable at the construction site of dark, if carry the floor light instrument of electric torch and so on, then can hinder other operations (such as overhauling).
Utility model content
The purpose of this utility model is the test pencil providing a kind of improvement, mainly solves existing test pencil and there is use inconvenience and flimsy problem.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A test pencil for improvement, the penholder comprising test nib and be connected with this test nib, is also comprised the lighting device removably connected by " Ω " type elastic clip and penholder, is arranged on the arm clamping device of pen arm end, and is enclosed within the gum cover at penholder two ends; The direction of illumination of described lighting device is consistent with the written direction of test.
Specifically, described lighting device comprises the housing be connected with " Ω " type elastic clip, and is arranged on the battery case, shift knob and the LED that also connect successively in this housing; Described LED direction of illumination is consistent with the written direction of test.
Specifically, described arm clamping device comprises " L " type bar be connected with penholder, the connecting rod be connected with this end, " L " type bar long limit, and the annular ring be connected with this connecting rod.
Further, the utility model also comprises setting on the annular rings and around its inwall cushion of a week.
Compared with prior art, the utility model has following beneficial effect:
(1) the utility model by setting up lighting device on test pencil, can realize floor light, thus make test pencil be applicable to the construction site of dark, and staff can be made to have freed hand to some other operation.
(2) the utility model is by arranging gum cover, when test pencil is dropped accidentally, can well for the shock of penholder provides a buffering, and then prevent penholder from damaging, effectively extend the serviceable life of test pencil.
(3) the utility model utilizes the arm clamping device arranged, and can strengthen the contiguity between test pencil and staff, prevent it from dropping.
(4) the utility model is practical, significantly facilitates the use of test pencil.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, the parts name that Reference numeral is corresponding is called:
1-tests nib, 2-penholder, 3-gum cover, 4-" Ω " type elastic clip, 5-housing, 6-LED lamp, 7-" L " type bar, 8-connecting rod, 9-annular ring.
Embodiment
As shown in Figure 1, the utility model comprises test nib 1, penholder 2, gum cover 3, lighting device and arm clamping device.Like the prior art, described test nib 1 is connected with penholder 2.Described gum cover 3 is enclosed within penholder 2 two ends, for providing buffering for dropping of penholder 2.Described lighting device is used for providing light source for test pencil, it is connected with penholder 2 by one " Ω " type elastic clip 4, and specifically, this lighting device comprises the housing be connected with " Ω " type elasticity 4, and be arranged on battery case, shift knob and the LED 6 also connected successively in this housing; Further, LED 6 direction of illumination is consistent with written 1 direction of test.
Described arm clamping device is enclosed within the arm of people when test pencil works, and it comprises " L " type bar 7 be connected with penholder 2, the connecting rod 8 be connected with this end, " L " type bar 7 long limit, and the annular ring 9 be connected with this connecting rod 8.
When needs use the utility model, first utilize annular ring 9 latch closure on human arm, in the present embodiment, for increasing the comfort level of latch closure, it is also provided with cushion in one week at annular ring 9 inwall.After latch closure lives the arm of people, test pencil just can drop easily again, so can guarantee operated by personnel's test pencil well.And at the poor construction site of some light, then can open shift knob, the light source utilizing LED to launch realizes illumination, guarantees the normal work of test pencil.
If test pencil drops accidentally, then utilize the buffering of gum cover 3, penholder 2 can be prevented damaged.
