[0040] Reference Figure 1 , Figure 2 and Figure 4 The docking mechanism 4 includes two heat insulation sleeves 41, the outer sides of which are located inside the bottom shell 1. Heating tubes 42 are fixedly connected to the inner sides of both heat insulation sleeves 41, and melting sleeves 43 are fixedly connected to the inner sides of both heating tubes 42. Mounting plates 44 are fixedly connected to the front and rear sides of both heat insulation sleeves 41. Mounting assemblies 45 are provided on the outer sides of the mounting plates 44. Each mounting assembly 45 includes multiple bolts 451, the bottom of which is threaded to the top of the mounting plates 44. Nuts 452 are threaded to the bottom of each bolt 451. A lifting assembly 4 is provided on the top of the top cover 2. 6. The lifting assembly 46 includes a handle 461, the left and right sides of which are rotatably connected to the top of the top cover 2. The top of the top cover 2 is provided with a placement groove 462. The front side of the bottom shell 1 is provided with a locking assembly 47, which includes a locking ring 471. The rear side of the locking ring 471 is fixedly connected to the front side of the bottom shell 1. The front side of the top cover 2 is fixedly connected with a buckle 472. The rear side of the bottom shell 1 is provided with a flipping assembly 48, which includes multiple rotating seats 481. The front sides of the multiple rotating seats 481 are all fixedly connected to the rear side of the bottom shell 1. Two flipping shafts 482 are rotatably connected between adjacent rotating seats 481.

[0041] Specifically, when the docking mechanism 4 is working, the heat insulation sleeve 41 on the inner side of the bottom shell 1 wraps the heating tube 42 to reduce heat loss during the heating process. The heating tube 42 is energized and heats up, transferring the heat to the inner molten sleeve 43, so that the molten sleeve 43 reaches the predetermined temperature. Through the cooperation of the heat insulation sleeve 41 and the heating tube 42, the molten sleeve 43 is heated efficiently.

[0042] The mounting plates 44 on the front and rear sides of the heat insulation sleeve 41 are fixed by the mounting assembly 45. The bolts 451 pass through the mounting plates 44 and are threadedly connected to the nuts 452. After tightening, the mounting plates 44 are fixed to the corresponding structure. Through the cooperation of the bolts 451 and the nuts 452, the heat insulation sleeve 41 is stably installed inside the bottom shell 1.

[0043] In the lifting assembly 46 at the top of the top cover 2, the handle 461 can rotate along the top of the top cover 2. When not in use, it can be placed in the placement slot 462. When the device needs to be moved, the handle 461 can be rotated out of the placement slot 462 and held. Through the cooperation of the handle 461 and the placement slot 462, the device can be conveniently lifted and stored.

[0044] In the locking assembly 47 on the front side of the bottom shell 1, when the top cover 2 is closed, the latch 472 on the front side of the top cover 2 engages with the locking ring 471 on the front side of the bottom shell 1 to lock the bottom shell 1 and the top cover 2. When opened, the latch 472 and the locking ring 471 are separated. Through the cooperation of the locking ring 471 and the latch 472, the stability of the bottom shell 1 and the top cover 2 after closing is ensured.

[0045] In the flip assembly 48 on the rear side of the bottom shell 1, the top cover 2 is rotatably connected to the rotating base 481 via the flip shaft 482. When the top cover 2 is opened, the flip shaft 482 rotates along the rotating base 481, causing the top cover 2 to flip backward. Through the cooperation between the rotating base 481 and the flip shaft 482, the top cover 2 can be flexibly flipped.

[0046] When docking is required, the top cover 2 is opened by flipping component 48, the parts to be docked are placed inside the melting sleeve 43, the heating tube 42 is energized to heat the melting sleeve 43, melting the outer rubber layer of the circuits on both sides. After docking is completed, the top cover 2 is closed, the locking component 47 is locked, and the moving device is moved by lifting component 46.

[0047] Working principle: The measuring mechanism 3 is operated to cut the external cable for which the current needs to be measured and pass it through the inlet and outlet seats 381 of the buffer components 38 on the left and right sides of the bottom shell 1. The rubber ring 382 on the inner side of the inlet and outlet seat 381 is in close contact with the surface of the cable to reduce wear when the cable passes through and enhance the sealing of the connection between the cable and the bottom shell 1. After the cable passes through the inlet and outlet seat 381, the positioning clamps 35 on the left and right sides of the inner side of the bottom shell 1 clamp the two ends of the cable respectively. The screw 36 on the top of the positioning clamp 35 is rotated so that the bottom of the screw 36 contacts the cable and keeps it pressed tightly to fix the position of the cable and prevent the cable from loosening and falling off during the measurement process.

[0048] After the cable is fixed, both ends contact the connecting rings 34 on the left and right sides of the protective shell 31 respectively. The connecting rings 34 transmit the current to the contact plate 33, and then the current is introduced into the current detection module 32 inside the protective shell 31 by the contact plate 33. The current detection module 32 starts to detect the current flowing through the cable. The detected data is displayed in real time on the display screen 371 of the operation component 37 on the top of the protective shell 31. According to the measurement requirements, the detection mode and related parameters can be adjusted by the button 372 of the operation component 37 to ensure the accuracy of the measurement data.

[0049] After the measurement is completed, rotate the screw 36 in the opposite direction to release the clamping clamp 35 from the cable and pull the cable out of the inlet / outlet seat 381.

[0050] When the cables need to be reconnected, operate the connection mechanism 4 to separate the latch 472 and the locking ring 471 of the locking assembly 47. The flipping shaft 482 of the flipping assembly 48 rotates along the rotating base 481, causing the top cover 2 to flip back and open.

[0051] The heat insulation sleeve 41 and the heating tube 42 and the fusion sleeve 43 inside the bottom shell 1 are exposed. The heat insulation sleeve 41 is fixed to the inside of the bottom shell 1 by the mounting plates 44 on the front and rear sides and the bolts 451 and nuts 452 of the mounting assembly 45. The two ends of the cable with the outer sheath cut are respectively placed inside the two fusion sleeves 43 to ensure that the part to be fused is aligned with the center of the fusion sleeve 43.

[0052] The heating element 42 is activated and begins to heat up after being powered on. The heat insulation sleeve 41 wraps around the outside of the heating element 42 to reduce heat loss to the outside and concentrate the heat to the inner melting sleeve 43. The temperature of the melting sleeve 43 gradually increases, contacts the outer rubber layer of the cable and melts it, thus achieving the connection of the cable sheath. After the welding is completed, the heating element 42 is turned off and the temperature of the melting sleeve 43 is allowed to drop slightly. The top cover 2 is then flipped forward and closed by the flipping component 48, so that the latch 472 and the locking ring 471 are re-engaged, thus locking the bottom shell 1 and the top cover 2. If it is necessary to move the device, the handle 461 in the placement groove 462 on the top of the top cover 2 is turned out for gripping. After the movement is completed, the handle 461 is turned back into the placement groove 462 for storage.
