Abstract
The utility model discloses a foldable shell body of a clamp current meter. The shell body includes a numerical control part shell body and a clamp arm part shell body which are connected to each other by a hinge portion; and the hinge portion includes a hinge piece arranged on the numerical control part shell body, a hinge piece arranged on the clamp arm part shell body and a hinge shaft for connecting the two hinge pieces to each other. By employing the hinge portion, the numerical control part shell body and the clamp arm part shell body can be turned, so that the shape of the whole foldable shell body turns from a straight plate shape into a shape that the numerical control part shell body is vertical to the clamp arm part shell body. The foldable shell body in the shape that the numerical control part shell body is vertical to the clamp arm part shell body is used for testing a vertical wire, and vise versa, the foldable shell body in the straight plate shape is used for testing a horizontal wire. With the foldable shell body of the clamp current meter, current testing operation can be effectively carried out by one operator standing on the ground. The application range is widened.

[utility model content]
Problem to be solved in the utility model is to provide a kind of folding split-core type current watch shell for the deficiency of above-mentioned prior art existence, and the current pincerlike meter that has possessed this housing not only can be measured horizontal wire but also be convenient to measure vertical electric wire.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
A kind of folding split-core type current watch shell, comprise the housing of numerical control portion and the housing of tong arm portion, its improvement is: the housing of numerical control portion is connected by the portion of being hinged with the housing of tong arm portion, the portion of being hinged comprises the pin-joint piece on the housing of pin-joint piece on the housing that is divided into numerical control portion and tong arm portion, and the jointed shaft that described pin-joint piece is linked together.
Compared with prior art, the utlity model has following advantage and beneficial effect:
Setting is hinged after portion, by pulling the housing of tong arm portion and the housing of numerical control portion, can make the utility model entirety convert the housing of tong arm portion to by straight board status and the housing of numerical control portion is mutually right angle, now for the electric wire of measuring vertical state, vice versa, the right angle state conversion cost utility model entirety being mutually by the housing of tong arm portion and the housing of numerical control portion is straight board status, at that time for measuring the electric wire of horizontality, greatly conveniently stand on that the operating personnel on ground are single carries out current measurement operation efficiently, service condition has obtained widening, therefore, compared with being straight tabular current pincerlike meter with simple entirety, fully demonstrate progressive of the present utility model.
