Detailed Implementation

[0025] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1-4 As shown, the present invention provides a technical solution: a clamp-on grounding resistance tester, including a resistance tester component 1, and an extended pulling component 2 is provided on the bottom surface of the resistance tester body 101.

[0027] The resistance tester assembly 1 includes a tester body 101. A rope groove 106 is opened on the top side of one side of the tester body 101. A thin round shaft 107 is rotatably installed at the outer edge of the middle part of the rope groove 106. An adjustment slot 108 is opened in the middle of the bottom surface of the tester body 101. An adjustment screw 109 is threaded into the bottom back of the tester body 101.

[0028] The extended pull assembly 2 includes an adjustable handle 201. The top surface of the adjustable handle 201 has several adjustable threaded holes 202 from top to bottom. A handle 203 is fixedly installed at the bottom end of the adjustable handle 201. A transition groove 204 is opened on one side of the handle 203. A damping shaft 205 is rotatably installed in the transition groove 204. A pull rope 206 is wound on the shaft of the damping shaft 205.

[0029] In this embodiment, a clamp head 102 is provided on the top surface of the tester body 101, and an operation button 103 is provided on the top side of the front of the tester body 101.

[0030] The front bottom of the tester body 101 is embedded with a display screen 104, and the top of one side of the tester body 101 is provided with a trigger 105. One end of the pull rope 206 is fixedly connected with the shaft body of the damping shaft 205, and the other end of the pull rope 206 passes through the rope slot 106 and is fixedly connected with the bottom outer edge of the trigger 105. The top end of the damping shaft 205 extends above the top surface of the handle 203, and a rotating knob is fixedly installed on the top end of the damping shaft 205. The damping shaft 205 is manually rotated to pull the pull rope 206, and the pull rope 206 can pull the trigger 105. Since the pull rope 206 passes through the rope slot 106, the rope slot 106 can pull the trigger 105 inward, so as to be equivalent to the electrician pressing the trigger 105 to separate the jaw 102, thereby facilitating the electrician to use the jaw-shaped grounding resistance tester to detect the depth of the electric box.

[0031] One end of the adjusting screw 109 extends into the adjusting slot 108, the adjusting handle 201 is movably inserted into the adjusting slot 108, the plurality of adjusting screw holes 202 are evenly arranged at equal distances, and the adjusting screw 109 is screwed with one adjusting screw hole 202. After the adjusting screw 109 is removed, the limitation on the adjusting handle 201 is released, and then the adjusting handle 201 is manually pulled out. After the adjusting handle 201 is pulled to a certain length, the adjusting screw 109 is screwed back. By screwing the adjusting screw 109 with the adjusting screw hole 202 corresponding to the current length, the adjusting handle 201 can be fixed at the current position, so that the overall length of the jaw-shaped grounding resistance tester can be conveniently adjusted.

[0032] Working principle: the overall length of the resistance tester can be changed to increase the working radius, which facilitates testing in narrow and deep areas. The specific adjustment steps are as follows: first, remove the adjusting screw 109. After the adjusting screw 109 is removed, the limitation on the adjusting handle 201 is released, and then the adjusting handle 201 is manually pulled out. After the adjusting handle 201 is pulled to a certain length, the adjusting screw 109 is screwed back. By screwing the adjusting screw 109 with the adjusting screw hole 202 corresponding to the current length, the adjusting handle 201 can be fixed at the current position, so that the overall length of the jaw-shaped grounding resistance tester can be conveniently adjusted.

[0033] After adjusting the overall length of the clamp-type grounding resistance tester, the rod body of the adjusting handle 201 can be held to facilitate the extension of the clamp-type grounding resistance tester into the deep position of the electric box. After moving the clamp-type grounding resistance tester to the specified test position, the damping shaft 205 is manually rotated to pull the pull rope 206, which in turn pulls the trigger 105. Since the pull rope 206 passes through the rope slot 106, the rope slot 106 can pull the trigger 105 inward, which is equivalent to the electrician pressing the trigger 105 to separate the jaw 102, thereby facilitating the electrician to use the clamp-type grounding resistance tester to detect the deep position of the electric box.

[0034] In summary, the clamp-type grounding resistance tester only needs to manually pull out the adjusting handle 201, and after adjusting the handle 201 to a certain length, the adjusting screw 109 is screwed back to fix the adjusting handle 201 at the current position, thereby conveniently adjusting the overall length of the clamp-type grounding resistance tester, thereby increasing the working radius by changing the overall length of the resistance tester. Since the pull rope 206 passes through the rope slot 106, the rope slot 106 can pull the trigger 105 inward, which is equivalent to the electrician pressing the trigger 105 to separate the jaw 102, thereby facilitating the electrician to use the clamp-type grounding resistance tester to test the narrow and deep area of the electric box, and the utility is stronger.

[0035] Although the utility model has been described in detail above with general description and specific embodiments, some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the utility model, all belong to the scope of protection required by the utility model.
