Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0026] Please see Figure 1 - Figure 6 The present invention provides the following technical solution:

[0027] A power testing instrument includes a testing instrument body 1 and a wire clamp 2. The wire clamp 2 is fixedly connected to one end of the testing instrument body 1, and the wire clamp 2 is composed of two symmetrically distributed clamping rods, and the two clamping rods form a clamp.

[0028] The detector body 1 is fixedly connected to two sides of a fixed shaft 3. A fixed ring is fixedly connected to the outer end of the fixed shaft 3 away from the detector body 1. A positioning groove 5 is provided on the outer side of the outer end of the fixed shaft 3 away from the fixed ring. A rotating sleeve 6 is rotatably connected to the outer side of the fixed shaft 3. A positioning ring 8 is fixedly connected to the inner side of the rotating sleeve 6 near the detector body 1. The positioning ring 8 is rotatably connected inside the positioning groove 5. A rotating spring 7 is fixedly connected between the positioning ring 8 and the fixed ring. The rotating spring 7 is located on the outer side of the fixed shaft 3.

[0029] The rotating sleeve 6 is fixedly connected to a ring of equally spaced fixing strips 9, and a receiving roller 10 is engaged with the outer side of the rotating sleeve 6.

[0030] The inner side of the receiving roller 10 is provided with a fixed groove 11 that is distributed in a ring at equal intervals, and the fixing strip 9 is engaged and connected to the inside of the fixed groove 11.

[0031] Both ends of the receiving roller 10 are fixedly connected to intercepting rings 12, and the outer side of the intercepting rings 12 is provided with limiting grooves 13 that are distributed in an annular pattern.

[0032] The outer side of the collecting roller 10 is wound with a detection wire 19, and the detection wire 19 is located between two intercepting rings 12. The outer side of the detection wire 19 away from the collecting roller 10 is slidably connected to a positioning block 4, and the end of the detection wire 19 is fixedly connected to a limiting ring 20. The limiting ring 20 is in contact with the side of the positioning block 4 away from the collecting roller 10, and the positioning block 4 is fixedly connected to one side of the detector body 1.

[0033] A fixed block 14 is fixedly connected to one side of the detector body 1, and a movable ring 15 is slidably connected inside the fixed block 14. The side of the movable ring 15 away from the fixed block 14 is engaged with the inside of the limiting groove 13. A friction block 16 is fixedly connected to the side of the movable ring 15 away from the detector body 1, and the friction block 16 extends to the outside of the fixed block 14. A positioning spring 17 is fixedly connected between the inside of the fixed block 14 and the movable ring 15.

[0034] The detector body 1 has protective boxes 18 fixedly connected to both sides, and the receiving roller 10 and the fixing block 14 are both located inside the protective box 18. The friction block 16 and the fixing block 14 on the side near the friction block 16 both extend to the outside of the protective box 18. Example 2:

[0035] Based on Example 1, its specific working principle is as follows:

[0036] In the operation of this power testing instrument, the jaws of the wire clamp 2 are opened and clamped onto the single cable to be tested. The jaws of the wire clamp 2 are ensured to be fully closed. At this time, the current value detected by the wire clamp 2 will be displayed on the top of the instrument body 1 to monitor the cable current. Thus, the instrument body 1 can be used as a current clamp meter.

[0037] First, connect the detection wire 19 on the side of the limiting ring 20 away from the positioning block 4 to the circuit, so that the detection wire 19 can be connected to the plug, socket and terminal block, so that the detection wire 19 connects the detector body 1 and the circuit.

[0038] When the detector body 1 and the circuit are connected, ensure that the connection between the detection wire 19 and the circuit is firm. At this time, slide the friction block 16, and drive the movable ring 15 to slide inside the fixed block 14, so that the fixed block 14 compresses the positioning spring 17. At this time, the friction block 16 will drive the movable ring 15 away from the inside of the limiting groove 13, and at the same time pull the detector body 1, so that the detection wire 19 drives the receiving roller 10 to rotate outside the receiving roller 10, and then the detection wire 19 slides and extends inside the positioning block 4. When the detection wire 19 reaches the appropriate length, release the friction block 16, so that the positioning spring 17 drives the movable ring 15 to slide inside the fixed block 14 to the inside of the limiting groove 13, thereby fixing the position of the receiving roller 10, and thus realizing the adjustment of the length of the detection wire 19.

[0039] When the detection lead 19 needs to be stored, the friction block 16 drives the movable ring 15 to slide inside the fixed block 14, causing the fixed block 14 to compress the positioning spring 17. At this time, the friction block 16 will drive the movable ring 15 away from the inside of the limiting groove 13. Then, the rotating spring 7 will drive the fixed ring outside the positioning ring 8 to rotate, causing the positioning ring 8 to rotate inside the positioning groove 5. At the same time, the positioning ring 8 will drive the rotating sleeve 6 to rotate, causing the rotating sleeve 6 to drive the storage roller 10 to rotate on its outside. The rotation of the storage roller 10 will wind the detection lead 19 to the outside of the detection lead 19, thereby storing the detection lead 19.
