Current detection pen convenient for recording data

Abstract

A current detection pen convenient for recording data disclosed by the invention comprises a handle, a switching cavity penetrating front and back and provided with an upward opening is formed in the handle, rotating shaft cavities in bilateral symmetry are formed in the left wall and the right wall of the switching cavity respectively, a switching rotating shaft is rotatably connected between the left wall of the rotating shaft cavity on the left side and the right wall of the rotating shaft cavity on the right side, left and right symmetrical rotating shaft fixing plates fixedly sleeve the outer circular surface of the switching rotating shaft in the rotating shaft cavities, and torsion springs surrounding the switching rotating shaft are fixedly connected between the left and right rotating shaft fixing plates and the left and right walls of the left and right rotating shaft cavities respectively. A conductive rod and a writing pen can be combined into a whole through a switching structure, a user can conveniently carry out current detection and writing recording work after detection, the magnitude of current is recognized through an electromagnet and then transmitted into an analyzer, the detection result is more reliable, and meanwhile, the device can automatically supplement ink for the writing pen, and is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of current detection, in particular to a current detection pen which is convenient for recording data. Background technique [0002] The current detection pen is an electrical tool used to test whether the electric wire is charged. When the electrician is working, due to the influence of external unfavorable factors, once it is difficult to replace the current detection and writing pen, it will make it difficult for the electrician to work and affect work efficiency. The existing current detection pen cannot be replaced with the writing pen at will, and an electrician is required to manually replace it, which affects work efficiency. A current detection pen that is convenient for recording data described in the present invention can solve the above problems. Contents of the invention [0003] In order to solve the above problems, this example designs a current detection pen that is convenient for recordin...
