The analysis mechanism 8 can also be adjusted in direction by the distance adjustment mechanism 7. After the adjustment is completed, lift the pull-down mechanism 4, and the pull-down mechanism 4 can drive the clamping mechanism 6 and the analysis mechanism 8 to move upward through the support sleeve 5. When the clamping mechanism 6 and the analysis mechanism 8 are moved to the upper side of the cable, the clamping mechanism 6 and the analysis mechanism 8 are controlled by the moving wheel 2 to move horizontally to the top of the cable, and the pull-down mechanism 4 is released. The pull-down mechanism 4 can drive the clamping mechanism 6 and the analysis mechanism 8 to be clamped to the cable, and the analysis mechanism 8 can analyze the cable line loss. The moving wheel 2 can be driven to move by pushing the push handle 3, thereby driving the clamping mechanism 6 and the analysis mechanism 8 to move on the cable, so that the line loss analysis can be performed on different positions of the cable.

[0032] When adjusting the distance between the two ends of the analysis mechanism 8, the power member 71 is rotated. The power member 71 is specifically a motor. The output shaft of the power member 71 drives the first bevel gear 72 to rotate, and the first bevel gear 72 drives the second bevel gear 75 and the connecting rod 74 to rotate. The rotation of the connecting rod 74 drives the screw rod 73 to rotate.

The telescopic rods 78 on both sides can drive the two ends of the analysis mechanism 8 to approach or move away from each other, thereby realizing the adjustment of the cable power loss analysis distance. The two ends of the analysis mechanism 8 can also adjust the direction by rotating the universal ball 792 in the ball sleeve 791, so that the analysis mechanism 8 can be smoothly inserted into the cable. The protrusion 793 can be close to the universal ball 792, thereby increasing the rotation resistance of the universal ball 792, so that the analysis mechanism 8 can maintain the adjusted direction.

[0035] When conducting an electric loss analysis on the cable, the distance between the two U-shaped grooves 86 can first be adjusted through the distance adjustment mechanism 7. After the adjustment is completed, the direction of the U-shaped groove 86 on the connecting block 87 can be adjusted through the universal assembly 79. After the adjustment is completed, the two U-shaped grooves 86 are clamped on the cable, and the compression spring 884 can push the clamping plate 883 to move, thereby pushing the cable to be close to the line loss sensor 85. The line loss sensors 85 on both sides can collect various data of the current flowing through the cable, and transmit them to the analyzer 82 for analysis through the hard wire 84 and the soft wire 83. The analyzer 82 can analyze the power loss of the cable at this distance. The analyzer 82 can be turned to control its rotation on the circular sleeve 81, so that the orientation of the analyzer 82 can be adjusted to facilitate the acquisition of the analysis results.
