Based on the above, one end of the two clamp bodies is hinged, and the two clamp bodies are respectively provided with fixing holes. The fixing holes fix the two clips together.

Based on the above, the middle parts of the two clamp bodies are hinged, one end of the two clamp bodies is correspondingly provided with a handle, the clamping member is a spring, and the spring is pushed between the two handles.

Based on the above, the clip body and the appliance end are respectively provided with wire jacks, and the two ends of the wires are respectively provided with plugs corresponding to the wire jacks. the

Compared with the prior art, the present invention has outstanding substantive features and significant progress. Specifically, the present invention adopts the design of arc-shaped groove or tooth-shaped groove, which is convenient for clamping irregular ground conductors such as steel bars; it is set by spring or bolt, which is convenient for installation with disassembly. The detachable ground wire connection device has the advantages of scientific design, can clamp irregular ground conductors such as steel bars, and is convenient for installation and disassembly.

Detailed ways

The technical solutions of the present invention will be described in further detail below through specific implementation methods.

Example 1

As shown in Figure 1, a detachable ground wire connection device includes a ground terminal, an electrical appliance terminal and a wire, and the two ends of the wire are respectively connected to the ground terminal and the electrical appliance terminal; the ground terminal includes a clamp The clamping part and two corresponding clamping bodies 1 are connected flexibly, the clamping parts are respectively connected to the two clamping bodies 1, and the wire is connected to one of the clamping bodies 1; A clip groove 2 is correspondingly provided on one of the clip bodies 1 , and clip pieces 3 are correspondingly provided on the two clip bodies 1 . Clamp groove 2 is used for clamping steel bar usefulness, and clamp piece 3 is used for clamping flat iron usefulness.

The clamping groove 2 is an arc-shaped groove, and the arc-shaped grooves are not less than one pair. Each pair of the arc-shaped grooves has the same size and is respectively arranged on the two clamp bodies 1. differ in size from each other. The purpose of setting the arc-shaped groove is to make the detachable ground wire connecting device conveniently fixed on the steel bar, and the different shapes of the arc-shaped groove are also to be able to adapt to steel bars of different diameters.

One end of the two clamp bodies 1 is hinged, and the two clamp bodies 1 are respectively provided with fixing holes 4 correspondingly. The clamping parts are a pair of bolts and nuts arranged in cooperation, and the bolts and the nuts pass through the The fixing holes fix the two clamp bodies 1 together. The advantage of this fixing method is that it can be fixed on the steel bar very well, and the screw connection is used to ensure that the fixing is very firm, and it is not easy to fall off during the construction process. The threaded connection here can also be replaced by other connection structures having the same effect.

The clamp body 1 and the appliance end are respectively provided with wire jacks 5 , and the two ends of the wires are provided with plugs corresponding to the wire jacks 5 .

Example 2

The difference between Embodiment 2 and Embodiment 1 is that a different fixing method is provided: the middle parts of the two clamp bodies 1 are hinged, and the ends of the two clamp bodies 1 are correspondingly provided with a handle 6, and the clamping member is a spring 7. The spring 7 is mounted between the two handles 6 . The advantage of this fixing method is that the detachable ground wire connection device can be fixed on or removed from the steel bar more conveniently and quickly.

Example 3

The difference between embodiment 3 and embodiment 1 is that a different clamping groove shape is provided: the clamping groove is a toothed groove, and the toothed grooves are not less than one pair, and the size of each pair of the toothed grooves is the same and They are respectively arranged on the two clip bodies, and the sizes of different pairs of the tooth-shaped grooves are different from each other.
