The secondary devices are connected together through secondary small wires according to certain functional requirements to form a secondary wiring, or called a secondary circuit, which is an essential important component for ensuring safe production, economic operation and reliable power supply of an electric power system.

In order to ensure the operation of secondary equipment, the wiring strength of a secondary small wire is generally required to be tested, the traditional detection mode of the secondary small wire is to clamp the secondary small wire by using a sharp-mouth clamp for detection, the secondary small wire is easily clamped and broken by the detection mode, and the wiring is required to be performed again, so that the working efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to above-mentioned prior art in the long flat nose pincers problem disconnected with the secondary small line clamp easily, provide an electric power system secondary small line wiring strength test pincers, can realize through following technical scheme:

the utility model provides a power system secondary small-wire wiring intensity test pincers, includes first handle and second handle, first handle is articulated with second handle one end, first handle and second handle keep away from articulated pot head and are equipped with insulating handle, be connected with reset spring between first handle and the second handle, reset spring both ends are connected in first handle and second handle respectively, first handle and second handle hinged end fixedly connected with are flaky stainless steel clamping piece respectively.

By adopting the technical scheme, the clamping piece increases the contact area of the test clamp and the secondary small wire, and prevents the test clamp from clamping the secondary small wire in the wire clamping process; in addition, the flaky clamping piece can conveniently penetrate into the space between two secondary small wires with narrow space, and the applicability of the test clamp is improved.

The utility model discloses further set up to: the first handle and the second handle are arranged in a bending mode.

Through adopting above-mentioned technical scheme, crooked setting is convenient to stretch into the narrow space that first handle and second handle of being not convenient for stretched into with the test pincers, improves the practicality of test pincers.

The utility model discloses further set up to: and one opposite side of the two clamping sheets is fixedly connected with a protective layer, and the protective layer is made of rubber.

By adopting the technical scheme, the protective layer made of the rubber material increases the friction force between the clamping sheet and the secondary small wire, so that the wiring strength of the secondary small wire is conveniently detected; in addition, the rubber layer has elasticity, so that the secondary small wire is clamped to play a role in buffering, and the secondary small wire is prevented from being damaged by clamping.

The utility model discloses further set up to: the handle is far away from the clamping piece one end fixedly connected with arch, articulated on the second handle have the buckle.

By adopting the technical scheme, when the test clamp is not used, the retaining ring is buckled on the bulge of the grip, so that the test clamp is convenient to store.

The utility model discloses further set up to: the surface of the handle is processed with patterns.

Through adopting above-mentioned technical scheme, the frictional force between human hand and the handle is increased to the decorative pattern, prevents that test pincers from taking place to skid with human hand when using.

To sum up, the utility model discloses a beneficial technological effect does:

1. the clamping piece of the test clamp increases the contact area with the secondary small wire, so that the test clamp is prevented from clamping the secondary small wire in the wire clamping process;

2. the clamping piece is sheet-shaped, so that the clamping piece can conveniently penetrate between two secondary small wires with narrow space, and the applicability of the test clamp is improved;

3. the protective layer made of rubber material increases the friction force between the clamping sheet and the secondary small wire; in addition, the rubber layer has elasticity, so that the secondary small wire is clamped to play a role in buffering, and the secondary small wire is prevented from being damaged by clamping.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Examples

As shown in fig. 1, for the utility model discloses a power system secondary small-wire wiring strength test pincers, including being first handle 1 and the second handle 2 of crooked setting, first handle 1 is articulated with 2 one ends of second handle, first handle 1 and second handle 2 keep away from articulated pot head and are equipped with insulating handle 3, be connected with reset spring 4 between first handle 1 and the second handle 2, reset spring 4 both ends are respectively in first handle 1 and 2 fixed connection of second handle, first handle 1 and 2 hinged ends of second handle are fixedly connected with holding piece 5 respectively (refer to fig. 2), holding piece 5 is flaky stainless steel piece. The clamping piece 5 increases the contact area of the test clamp and the secondary small wire, and prevents the test clamp from clamping the secondary small wire in the wire clamping process; in addition, the sheet-shaped clamping piece 5 can conveniently penetrate into the space between two secondary small wires with narrow space, and the applicability of the test clamp is improved. The first handle 1 and the second handle 2 are bent to be convenient for extending the clamping piece 5 of the test clamp into a narrow space where the first handle 1 and the second handle 2 are not convenient to extend into, so that the practicability of the test clamp is improved. The opposite sides of the two clamping pieces 5 are fixedly connected with a protective layer 6, and the protective layer 6 is made of rubber. The protective layer 6 made of rubber material increases the friction force between the clamping sheet 5 and the secondary small wire; in addition, the rubber layer has elasticity, so that the secondary small wire is clamped to play a role in buffering, and the secondary small wire is prevented from being damaged by clamping.
