[0002] Wires refer to products with a small number of cores, small diameter and simple structure. They are materials used for electricity, communications and related transmission purposes. Wires refer to conductors that transmit electrical energy. Generally speaking, there are many wires indoors, and many wires are gathered in each place. When these wires are damaged, they need to be detected and found, so a line loss tester is needed.

[0003] For example, the multi-line damage tester with publication number CN214669386U has a circuit board arranged in the outer shell, a hand is inserted between the outer shell and the fixing belt, and the outer shell is held, and the utility model is used for line damage testing;

[0004] The multi-line loss tester connects a copper test ring to the connecting wire of the circuit board and tests the damaged part of the line through the copper test ring. However, since there is no extension structure at the copper test ring, if the measured line is high from the ground, or the measured line is placed in a narrow area (for example, in a high-voltage cabinet or a measuring panel cabinet), the staff can only rely on ladders, stools and other climbing tools, or bend and curl up in a small area to work, which makes it difficult for the staff to approach the measured line and inconvenient to operate, so the use effect is not good. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a line loss tester with good use effect, which solves the problem of existing multi-line loss testers that if the measured line is high above the ground, or the measured line is placed in a narrow area, the staff can only rely on ladders, stools and other climbing tools, or bend and curl up in a small area to work, which makes it difficult for the staff to approach the measured line and inconvenient to operate.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a line loss tester with good use effect, including a shell and a cover body, the front end face of the shell is threadedly connected to the cover body through a plurality of bolts, a circuit board is installed inside the shell, a first horizontal plate is fixedly connected to the lower right side of the shell, and a first set of plates is fixedly connected to the top of the first horizontal plate, a second set of plates is sleeved on the upper outer wall of the first set of plates, and a connecting mechanism is installed on the outer wall of the second set of plates, a second horizontal plate is fixedly connected to the upper surface of the second set of plates, and a fixing mechanism is installed on the upper part of the interior of the shell.

[0007] Preferably, the connecting mechanism includes a plastic wire clamp fixedly connected to the front end face of the second horizontal plate, the left side of the plastic wire clamp holds a copper test ring, the lower outer wall of the second set of plates is fixedly connected to the third horizontal plate, the lower right side of the third horizontal plate is fixedly connected to a pair of arc blocks, and the inner side of the arc blocks is rotatably connected to a baffle through a rotating shaft, the outer wall at the lower left bevel of the baffle is gap-matched with the inner wall at the corresponding groove of the first set of plates, and an elastic component is installed in the middle of the baffle.

[0008] Preferably, the elastic component includes a baffle rod fixedly connected to the outer wall of the second set of plates, and the middle outer wall of the baffle rod is gap-matched with the inner wall of the through groove of the baffle plate. A spring is installed on the left outer wall of the baffle rod, and both ends of the spring are respectively fixedly connected to the second set of plates and the baffle plate.

[0009] Preferably, the fixing mechanism includes a screw connected to the internal thread at the top of the shell, and a rotating head is fixed to the upper surface of the screw, a pressure plate that fits the upper surface of the circuit board is rotatably connected to the bottom of the screw, rectangular blocks are fixed to the left and right sides of the pressure plate, and a telescopic rod fixed to the inside of the shell is fixed on the upper surface of the rectangular block.

[0012] Beneficial Effects

[0013] The utility model provides a line loss tester with good use effect, which has the following beneficial effects:

[0014] When it is necessary to perform a line loss test on the wires in a higher or narrow area, the baffle can be rotated to the right so that the lower left bevel of the baffle leaves the groove of the first set of plates. At the same time, the baffle cooperates with the baffle rod and the second set of plates to allow the spring to undergo elastic deformation. Then, the baffle drives the second set of plates to move on the first set of plates through the third horizontal plate. The first set of plates drives the copper test ring to move through the second horizontal plate and the plastic wire clamp to extend the copper test ring. Then, the baffle is released so that the lower bevel of the baffle is reset under the elastic force of the spring and enters the corresponding groove of the first set of plates. In this way, the copper test ring can be used to perform line loss tests on wires in higher or narrow areas, so the use effect is better. BRIEF DESCRIPTION OF THE DRAWINGS
