In order to solve the technical problem, the embodiment of the utility model provides a pincerlike ground resistance tester, binding clip including handle and handle upper portion, including the binding clip on handle and handle upper portion, wherein, the binding clip include first fixed binding clip and second activity binding clip, second activity binding clip bottom end connection has the pincers handle, the pincers handle exposes in handle one side, and the handle opposite side is equipped with the portion of holding, the portion of holding is four inside sunken recesses, it has the silica gel pad to paste inside the recess, first fixed binding clip and second activity binding clip symmetry set up, binding clip thickness is less than handle thickness, binding clip front end radian is less than the rear end radian size.

Furthermore, a plurality of function buttons and a liquid crystal display screen are arranged on the surface of the handle.

Furthermore, the side wall of the clamp handle is provided with a plurality of anti-slip strips.

Further, the caliber of the jaw of the forceps head is 30mm multiplied by 42 mm.

By adopting the technical scheme, the utility model discloses beneficial effect as follows: the embodiment of the utility model has the advantages that the four grooves are arranged on one side of the handle, the grooves are matched with the outline of the fingers, when in use, the fingers are placed in the grooves, and the silica gel pads are also pasted on the grooves, so that the fingers of an operator feel comfortable, do not feel pain, and do not influence the detection efficiency; the front end radian of keeping silent is less than the rear end radian, and its thickness is thinner than the thickness of keeping silent rear end handle, makes keep silent and can stretch into in the narrow space and detect, and application range is wider.

Fig. 1 is a schematic front view of the present invention;

fig. 2 is a usage state diagram of the present invention.

Wherein: 10 is a handle; 101 is a hand holding part; 102 is a groove; 103 is a multifunctional key; 104 is a liquid crystal display screen; 105 is a silica gel pad; 20 is a tong head; 201 is a first fixed binding clip; 202 is a second movable binding clip; 203 is a forceps handle; 204 are cleats.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1-2, the utility model provides a pincerlike ground resistance tester, binding clip 20 including handle 10 and handle upper portion, wherein, the binding clip include first fixed binding clip 201 and second activity binding clip 202, second activity binding clip 202 bottom end connection has pincers handle 203, pincers handle 203 exposes in handle 10 one side, and handle 10 opposite side is equipped with holds portion 101, hold portion 101 is four inside sunken recess 102, and recess 102 suits with the finger, and during the specific use, the big finger presses pincers handle 203, and other fingers are placed in the recess, and the operation is light comfortable.
