Detailed Description

The present invention will be described in further detail with reference to examples.

The utility model discloses an universal meter dysmorphism pen-shape meter, including a shell 3, set up in a shell 3 and stretch out a shell 3 outside electrically conductive core 1, the cladding sets up at the insulating layer 2 of electrically conductive core 1 outer wall, a shell 3 is the L type structure that horizontal part 31 is longer than vertical portion 32, the horizontal part 31 that shell 3 was stretched out to the one end level of electrically conductive core 1 and insulating layer 2, the other end is worn out perpendicularly and is on a parallel with horizontal part 31 from the vertical portion 32 of a shell 3, electrically conductive core 1 diameter is not more than 3 millimeters, the external diameter of the outer terminal surface that electrically conductive core 1 and insulating layer 2 formed is not more than 5 millimeters. The conductive core 1 is a tung tree core, and the insulating layer 2 is made of rubber, PVC, polyvinyl chloride and the like.

The length of the horizontal part 31 of the pen shell 3 is more than 100mm, the length of the horizontal part 31 of the pen shell 3 is 6-10 times of the length of the vertical part 32, and the length of the conductive core 1 and the insulating layer 2 horizontally extending out of the horizontal part 31 is more than 500 mm.

The length of the conductive core 1 and the insulating layer 2 vertically penetrating out of the vertical part 32 of the pen shell 3 is 8-20mm, and the vertical penetrating position is located at 1/3-2/3 of the length of the vertical part 32.
