Specific implementation mode
Below in conjunction with drawings and examples, the present invention is described in further detail.
A kind of electrical maintenance multimeter of the utility model；Including outer housing 3, the side wall of outer housing 3 is provided with annular handle
1, shell 3 is rotatablely connected with handle 1 by shaft, and the upper end centre position of handle 1 is provided with Anti-slip cover 8, handle 1 and Anti-slip cover
8 bond connection by glue, can realize that both hands lift outer housing 3 by annular handle 1, easy to carry.
LED display 2 is provided with above the front surface of outer housing 3, outer housing 3, which is bonded with LED display 2 by glue, to be connected
It connects；The lower section of LED display 2 is provided with range disk 7, and the surface of range disk 7 is provided with range switch 6, and range disk 7 is opened with range
6 are closed to be rotatablely connected by shaft；The lower section of range disk 7 is provided with jack 5, and test pencil 4 is provided on jack 5, and 4 one end of test pencil are inserted
Enter to the inside of jack 5, the other end is provided with probe jacket 16, and the inside of probe jacket 16 is cased with test probe hook 15；It visits
It is cased with spring between end protective cover 16 and test probe hook 15, and spring is fixed on the inner wall of probe jacket 16.
The rear surface upper and lower ends of outer housing 3 are symmetrically arranged with rubber band 10, and rubber band 10 is cylindrical structure, outer housing 3 with
Rubber band 10 is fixed by screws.10 both sides of rubber band are symmetrically arranged with cheese 9, and each cheese 9 is weldingly fixed on sliding block 11
