[0068] Wherein, the adjustment mechanism 200 includes an adjustment member 210 and an extension sleeve 220;

[0069] The adjusting member 210 is installed on the extension sleeve 220;

[0070] The extension sleeve 220 is sleeved and installed on the sheath structure 100 through the adjusting member 210 .

The adjustment member 210 can also adjust the depth of the circuit detector in the installation groove 120, so as to adapt to circuit detectors of different lengths. The fastening device 300 can better fix the circuit detector and facilitate user operation.

[0072] In this embodiment, the sheath structure 100 is made of insulating material, and may be a hard shell made of polyvinyl chloride or other insulating materials, which is not limited here.

[0073] It should be noted that the sheath structure 100 is a hard shell to ensure the use of the adjustment member 210, which is explained here.

[0074] In one embodiment, the sheath structure 100 includes a sheath member 110;

[0075] The protective cover 110 is provided with a waterproof layer 111, an anti-corrosion layer 112, a heat insulation layer 113 and an insulating layer 114;

[0076] The waterproof layer 111 is disposed on the outer surface of the protective cover 110;

[0077] The anti-corrosion layer 112 is disposed on one side of the waterproof layer 111;

[0078] The heat insulation layer 113 is arranged on a side of the anti-corrosion layer 112 away from the waterproof layer 111;

[0079] The insulating layer 114 is disposed on a side of the heat insulation layer 113 away from the anti-corrosion layer 112 .

[0080] In this embodiment, the waterproof layer 111 is used to prevent most of the water from penetrating into the protective kit 110 during detection in rainy weather, thereby causing damage to the circuit tester. The anti-corrosion layer 112 is used to increase the service life of the protective kit 110. The heat insulation layer 113 is used to prevent excessive heat generated by the circuit tester during detection from being transferred to the user's hands. The insulating layer 114 is used to ensure the safety of the user.

[0081] It should be noted that the layered structure of the extension sleeve 220 is consistent with that of the protective sleeve 110 .

[0082] Furthermore, the circuit tester is a small testing device, not a large equipment, as explained here.

[0083] In one embodiment, the protective member 110 is provided with a plurality of mounting slots 120 adapted to the fastening device 300 .

[0084] In this embodiment, the mounting slot 120 is used to mount an external circuit tester.

[0085] In one embodiment, the adjusting member 210 includes a circular fixing member 211, a threaded rod 212 and a push block 213;

[0086] The extension sleeve 220 is provided with an extension hole 221, and the circular fixing member 211 is fixedly disposed in the extension hole 221;

[0087] One end of the threaded rod 212 is fixed to one side of the circular fixing member 211, and the other end of the threaded rod 212 passes through the sheath structure 100 and extends into the installation groove 120;

[0088] The push block 213 is installed at one end of the threaded rod 212 extending into the installation slot 120 .

[0089] In this embodiment, the extension sleeve 220 is rotated by the user, thereby driving the circular fixing member 211 and the threaded rod 212 to rotate. After the threaded rod 212 rotates, it drives the push block 213 to be continuously pushed forward through the threaded hole 130 on the sleeve structure 100. Rotating in the opposite direction can move the push block 213 in the opposite direction, making it convenient to push the circuit tester, so that corresponding adjustments can be made according to the length of the circuit tester.

[0090] In one embodiment, the fastening device 300 includes a plurality of elastic strips 310;

[0091] The number of the plurality of elastic strips 310 is consistent with the number of the mounting slots 120;

[0092] The elastic strip 310 is provided with an arc portion 311;

[0093] The elastic strip 310 is movably mounted in the mounting slot 120 , and a portion of the elastic strip 310 extends out of the mounting slot 120 ;

[0094] Each of the insulating spaces 400 is disposed between every two of the elastic strips 310 , and a mounting space 320 is formed in the middle of a plurality of the elastic strips 310 . The mounting space 320 is located in the middle of the plurality of the insulating spaces 400 .

[0095] In this embodiment, an insulating space 400 is formed between every two elastic strips 310, and an installation space 320 is also formed between several elastic strips 310. The circuit tester can be better placed in the installation space 320 through the arc portion 311 on the elastic strip 310, and the circuit tester first contacts the elastic strip 310, reducing the contact with the shielding kit 110, thereby enhancing the insulation effect of the shielding kit 110.

[0096] In one embodiment, a threaded hole 130 having a size matching that of the threaded rod 212 is formed on the sheath structure 100 , and the threaded rod 212 is threadedly connected to the threaded hole 130 .

[0097] In this embodiment, the threaded hole 130 on the sheath structure 100 drives the push block 213 to be continuously advanced.

[0098] In one embodiment, an annular groove 222 is provided on the inner wall of the extension sleeve 220;

[0099] At least two steel balls 223 are movably disposed in the annular slot 222;

[0100] The steel ball 223 partially extends out of the annular groove 222 and abuts against the outer wall of the sheath structure 100 .

[0101] In this embodiment, after the extension sleeve 220 is rotated, the extension sleeve 220 can be more conveniently rotated by a plurality of steel balls 223 abutting against the sheath structure 100 , thereby quickly adjusting the extension sleeve 220 .

[0102] In one embodiment, the extension sleeve 220 includes an active state and a fixed state;

[0103] When the extension sleeve 220 is in an active state, the extension sleeve 220 is rotated by an external force, and the circular fixing member 211 drives the threaded rod 212 to rotate at the same time. Since the threaded rod 212 is threadedly connected to the threaded hole 130, the extension sleeve 220 and the push block 213 are driven to move up and down. At this time, the extension sleeve 220 is movably connected to the sheath structure 100;

[0104] When the extension sleeve 220 is in a fixed state, the extension sleeve 220 is not rotated by an external force. At this time, the extension sleeve 220 is fixedly connected to the sheath structure 100 .

[0105] In this embodiment, through the above description of the state of the extension sleeve 220, it is clearer how to adjust the extension sleeve 220, and the utility model has a simple structure and is easy to operate.

[0106] It should be noted that if Figure 3 As shown, the cross-sectional area of ​​the push block 213 is smaller than the cross-sectional area formed by a plurality of elastic strips 310 , so that the push block 213 can move in the installation space 320 without hindrance.

[0107] Further, such as Figure 1 As shown, the extension sleeve 220 and the protective sleeve 110 are both cylindrical, so that the extension sleeve 220 can be easily rotated in the protective sleeve 110, and other shapes cannot rotate the extension sleeve 220. It is explained here that a round detector or a square detector can be inserted into the protective sleeve 110 without affecting the use of the device.

[0108] The working principle of this utility model:

[0109] An insulating space 400 is formed between every two elastic strips 310, and an installation space 320 is also formed between several elastic strips 310. The circuit tester can be better placed in the installation space 320 through the arc portion 311 on the elastic strip 310, and the circuit tester first contacts the elastic strip 310, reducing the contact with the shielding member 110, thereby enhancing the insulation effect of the shielding member 110. After the extension sleeve 220 is rotated by the user, the circular fixing member 211 and the threaded rod 212 are driven to rotate. After the threaded rod 212 is rotated, it passes through the threaded hole 130 on the sheath structure 100, thereby driving the push block 213 to continuously advance. Rotating in the opposite direction can make the push block 213 move in the opposite direction, which is convenient for pushing the circuit tester, so that the corresponding adjustment can be made according to the length of the circuit tester. After the extension sleeve 220 is rotated, the extension sleeve 220 can be more conveniently rotated through several steel balls 223 abutting on the sheath structure 100, thereby quickly adjusting the extension sleeve 220.
