Abstract

The utility model relates to a low voltage clamp type earth pin. The utility model is characterized in that: a spring which can automatically separate two handles and then clamps a clamp part is arranged on the central part of the clamp body; a clamp is made to automatically clamp a high voltage line and a low voltage line; symmetrical concave slots are arranged on the clamping position of the clamp part for clamping the high voltage line and the low voltage line and preventing slippage on a working line, thereby the construction operation is finished. The utility model has the characteristics of small volume, and flexible, convenient and practical construction during construction process, etc.

Description

Low pressure clamp-type earth rod

Technical field

The utility model relates to a kind of low pressure clamp-type earth rod, and particularly a kind of a kind of earthing tool commonly used when low-voltage power is constructed belongs to the technical field of high-low pressure concerned power.

Background technology

Existing common combination pliers with side cutting jaws is to do pincers handle, vice body and binding clip as a whole, clamp head part is shaped on pattern groove, the rear portion is shaped on the edge of a knife, two calipers connect together by fixed axis, and two axis bodies are rotated mutually by this axle, and come the restrictive axial play with the riveting ring,, cut, press from both sides, turn round three kinds of functions thereby finish to realize the switching of jaw.In the work progress of high-low pressure power transmission line, for the sake of security, need be with constructing again after the safety ground rod ground connection.Its operating process: at first cut off this working line, have or not with the electroscope check then, after determining no electricity, hanging earthing conductor, to guarantee the safety of personnel when constructing, the inventor has invented following low pressure clamp-type earth rod by the association between the low pressure earth rod of using at combination pliers with side cutting jaws and electric power.

Summary of the invention

The purpose of this utility model is: a kind of a kind of jaw type earthing tool of using when constructing of carrying in the high-and low-voltage circuit is provided, it has volume little, in work progress flexibly, characteristics such as convenience, practicality, it is characterized in that: thus the spring that can make two handles separately make the clamping of pincers portion automatically be provided with in the middle part of caliper body, make clamp clamp the high-and low-voltage circuit automatically, be provided with the concave groove of symmetry at the clamping position of pincers portion, be used for clamping and keep a grip on the high-and low-voltage circuit, prevent from working line, to slide, thereby finish construction operation.The utility model is made simple, and is easy to use, can clamp the high-and low-voltage circuit effectively, can landing when guaranteeing construction.

Description of drawings

Fig. 1 is a structural representation of the present utility model

Among the figure: 1 clamp body, 2 centre bolt axles, 3 concave groove A, 4 concave groove B, 5 springs, 6 taper knobs, 7 earth connection connecting screws.

Embodiment

Clamp body 1 is that aluminum alloy material is made, the structure that has bolt to flexibly connect in the middle part of handle and clamp portion, top at handle just has spring 5 to come support handle in the bottom of bolt, the two legs of handle is separated automatically, thereby make pincers portion clamp operation automatically, at every two concave grooves in the clamping position of clamp, in jaw, form two clamp holes that constitute by concave groove like this.Symmetry clamps working line, thereby finishes construction operation.On the handle of the wherein a slice between centre bolt axle 2 and spring 5 bolt that is connected ground wire is installed, is used for finishing ground connection work, be provided with taper knob 6 in the lower end of clamp body 1, taper knob 6 must be that the insulation material is made.

Claims (1)

1. low pressure clamp-type earth rod, comprise: clamp body (1), it is characterized in that: in clamp body (1) thus the middle part be provided with the spring (5) that can make two handles automatically separately make the clamping of pincers portion, be provided with the concave groove of symmetry at the clamping position of pincers portion, there are two concave grooves at every clamping position, forms two clamp holes that are made of concave groove like this in jaw.
