A guide tube is provided on the bottom surface of the U-shaped frame, and the guide tube corresponds to the guide hole. However, when using the above-mentioned device, multiple marking devices and a multimeter are required to test the wires. When using the multimeter, the operator needs to hold two test leads to test the wires, and it is impossible to fix the multimeter. A support platform needs to be found around the device to place the multimeter, which is quite inconvenient.

[0029] Example 1
[0030] Reference Figures 1-3 This is the first embodiment of the present invention, which proposes a device for detecting and accurately marking leakage current in power distribution lines. The device includes a fixing mechanism 1, with a multimeter body 4 mounted on top of the fixing mechanism 1. A marking tape placement mechanism 2 is fixedly connected to one side of the fixing mechanism 1. The fixing mechanism 1 includes a mounting plate 101, with two sets of symmetrically arranged first clamping blocks 103 slidably connected to the top of the mounting plate 101. A second clamping block 108 is slidably connected to the adjacent ends of both sets of first clamping blocks 103. By fixing the multimeter body 4 with the fixing mechanism 1, the portability of the multimeter body 4 is improved, and the testing can be completed without removing the multimeter body 4 during testing.
[0031] The marking tape placement mechanism 2 is equipped with a marking tape body 3. The marking tape placement mechanism 2 includes a U-shaped bracket 201, and a cutting blade 209 is provided on the U-shaped bracket 201. The cutting blade 209 facilitates the cutting of the marking tape body 3 and allows for adjustment of the cutting length according to usage requirements.
[0032] The top of the mounting plate 101 is provided with a first sliding groove 102. A reciprocating screw 104 is threadedly connected to the mounting plate 101. One end of the reciprocating screw 104 passes through the mounting plate 101 and is rotatably connected to the first sliding groove 102. Both sets of first clamping blocks 103 are provided with threaded grooves 110. The threads inside the two sets of threaded grooves 110 are symmetrically arranged. The inner walls of the two sets of threaded grooves 110 are threadedly connected to the reciprocating screw 104. By rotating the reciprocating screw 104, the two sets of first clamping blocks 103 are driven to move closer or further away from each other along the first sliding groove 102, thereby fixing the multimeter body 4.
[0033] A mounting block 105 is fixedly connected to the middle of the bottom end of the mounting plate 101. An elastic band 106 is fixedly connected to the mounting block 105. Two sets of locking blocks 107 are fixedly connected to one side of the mounting plate 101. The elastic band 106 is detachable. By setting the elastic band 106, it is easy to fix the fixing mechanism 1 to the user's wrist without holding the multimeter body 4, and it is also easy for the user to observe the values displayed on the multimeter body 4.
[0034] Both sets of first clamping blocks 103 are provided with second sliding grooves 109. The second clamping block 108 is slidably connected to the second sliding groove 109. A threaded rod 111 is threadedly connected to the second clamping block 108. The output end of the threaded rod 111 passes through the second clamping block 108 and is rotatably connected to the second sliding groove 109. By rotating the threaded rod 111, the second clamping block 108 is driven to slide along the second sliding groove 109, which brings the second clamping block 108 closer to the multimeter body 4 and fixes it.
[0035] Two sets of test leads 5 are fixedly connected to the multimeter body 4. The other end of the two sets of test leads 5 is engaged with the locking block 107. The locking block 107 is used to fix the test leads 5.
[0036] In this embodiment, rotating the reciprocating screw 104 drives the two sets of first clamping blocks 103 to move closer or further apart along the first slide groove 102 to fix the multimeter body 4. Rotating the threaded rod 111 drives the second clamping block 108 to slide along the second slide groove 109, bringing the second clamping block 108 closer to the multimeter body 4 and fixing it. This allows the device to fix various models of multimeter bodies 4. The elastic band 106 makes it easy to fix the fixing mechanism 1 to the user's wrist. When using it, only the two test leads 5 need to be inserted into the position to be tested, without having to remove the multimeter body 4. This makes it easy to observe the values displayed on the multimeter body 4, which improves the convenience of use.
[0037] Example 2
[0038] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a support rod 202 is fixedly connected to the U-shaped bracket 201, and a limiting disk 203 is threadedly connected to the other end of the support rod 202. A marking tape body 3 is sleeved on the outside of the support rod 202. By setting the limiting disk 203, the marking tape body 3 is limited, which helps to prevent the marking tape body 3 from falling off the support rod 202. When the marking tape body 3 is used up, it is only necessary to rotate the limiting disk 203 to separate it from the support rod 202, put a new marking tape body 3 on the outer wall of the support rod 202, and then reset the limiting disk 203. The structure is simple and easy to operate.
[0039] A support block 204 is fixedly connected to the side wall of the U-shaped bracket 201 away from the fixing mechanism 1. A telescopic sleeve 205 is fixedly connected to the top of the support block 204. A slider 207 is fixedly connected to the top of the telescopic sleeve 205. A spring 206 is sleeved on the outside of the telescopic sleeve 205. One end of the spring 206 is fixedly connected to the support block 204, and the other end of the spring 206 is fixedly connected to the slider 207. A limiting groove 208 is provided on the U-shaped bracket 201. The cutting blade 209 is slidably connected to the limiting groove 208. One end of the cutting blade 209 is fixedly connected to the slider 207. By pressing the slider 207, the cutting blade 209 is driven to slide along the limiting groove 208, so that the cutting blade 209 moves out of the U-shaped bracket 201 to cut the tape pulled out of the marking tape body 3. After cutting, the slider 207 is released, and the cutting blade 209 is reset under the action of the spring 206 and the telescopic sleeve 205.
[0040] In this embodiment, pressing the slider 207 drives the cutting blade 209 to slide along the limiting groove 208, causing the cutting blade 209 to move out of the U-shaped bracket 201 to cut the tape pulled out of the marking tape body 3. After cutting, the slider 207 is released, and the cutting blade 209 is reset under the action of the spring 206 and the telescopic sleeve 205, making it convenient for workers to cut the marking tape body 3 and wrap the marking tape body 3 around the outside of the leaking wire. The marking tape body 3 is made of bright colors and insulating materials, making it easy to find later and serving as a warning to prevent others from accidentally touching it. By setting the limiting plate 203, the marking tape body 3 is limited, which helps to prevent the marking tape body 3 from detaching from the support rod 202. When the marking tape body 3 is used up, it is only necessary to rotate the limiting plate 203 to separate it from the support rod 202, put the new marking tape body 3 on the outer wall of the support rod 202, and then reset the limiting plate 203. The structure is simple and easy to operate.
