Description

Test pencil

Technical field

The utility model relates to a kind of test pencil.

Background technology

The test pencil of Chu Shouing in the market, mainly comprise housing, neon tube, test contact, but the test contact of this test pencil does not generally all have stationary installation, need be on measurand during test with test contact point, the operator can't vacate hand and carry out other work, for a long time test contact point is also required great effort on measurand very much.

Technology contents

The purpose of this utility model is to overcome the weak point that prior art exists, and a kind of work test pencil easily is provided, and it can be fixed on test contact on the measurand easily.

For achieving the above object, the utility model is realized by following technical solution: the utility model test pencil, mainly comprise handle, test contact, described test contact is with rhampotheca, and this rhampotheca is made up of rhampotheca seat, cover hook, and the cover hook is connected on the rhampotheca seat, the upper end of cover hook is provided with the hook groove, be provided with spring between rhampotheca seat and the test contact, an end of spring is connected with test contact, and the other end of spring is connected with the rhampotheca seat.

Because in the above-mentioned technical solution, the test contact of test pencil is provided with rhampotheca, rhampotheca is provided with the hook groove, as long as grasping rhampotheca during test upwards promotes, rhampotheca moves up, expose the hook groove in the upper end indentation rhampotheca of test contact, the hook groove of rhampotheca is hooked on the measurand, unclamp hand, test contact can be pressed on the measurand under the effect of spring, thereby can easily test contact be fixed on the measurand, so the operator can vacate hand and carries out other work, be pressed on the measurand under the effect of spring owing to test contact simultaneously, thereby can guarantee that test contact contacts with the good of measurand.

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
