[0037] Handle 40 is fixedly connected to the side of sleeve 34 away from universal ball head 33, and a circle of silica gel pad can be adhered to the inner wall of handle 40 to improve the comfort of the worker when holding handle 40.

[0038] Clamping assembly includes support frame 500, small motor 51, push rod 53, toothed plate 54 and driven assembly 55.

[0039] Support frame 500 is fixedly connected to the inner wall of bottom side of shell 50, and is provided as a square frame; small motor 51 is fixedly connected to the inner wall of bottom side of support frame 500, and transmission shaft 52 is fixedly connected to the upper side of output end of small motor 51; push rod 53 is sleeved outside transmission shaft 52, and the upper side of push rod 53 passes through the upper side of support frame 500 and is slidingly connected with support frame 500; toothed plate 54 is fixedly connected to the upper side of push rod 53 to provide power for the rotation of driven assembly 55; driven assembly 55 is provided on the inner wall of rear side of shell 50 and is provided with two groups, which are symmetrically arranged on both sides of toothed plate 54.

[0040] Driven assembly 55 includes fan-shaped toothed plate 551, driven rod one 552, driven rod two 553 and clamping head 555.

[0041] The fan-shaped tooth plate 551 is rotationally connected to the rear inner wall of the shell 50, and is in meshing rotation with the tooth plate 54; the driven rod one 552 is fixedly connected to the fan-shaped tooth plate 551, the driven rod two 553 is rotationally connected to the rear inner wall of the shell 50, and the upper sides of the driven rod one 552 and the driven rod two 553 are connected through two front and rear parallel swing rods 554; the clamping head 555 is fixedly connected to one side of the two parallel swing rods 554.

[0042] The driven rod one 552 and the driven rod two 553 are rotationally connected with the two parallel swing rods 554, and through the cooperation between the tooth plate 54 and the fan-shaped tooth plate 551, the swing rods 554 can be slightly swung left and right to clamp the cable to be detected between the clamping head 555.

[0043] The push rod 53 is square and has a threaded hole formed therein, the transmission shaft 52 is a threaded rod, and the transmission shaft 52 is rotationally connected with the push rod 53. Through the square shape, the push rod 53 can be prevented from rotating with the transmission shaft 52 when the transmission shaft 52 rotates, so that the push rod 53 can only slide up and down.

[0044] The clamping head 555 is made of high-permeability material and can effectively concentrate the magnetic field. The inner wall of the clamping head 555 (i.e. the clamping portion) is provided with a Hall element. When current passes through the measured cable, a magnetic field is generated around it. The clamping portion of the clamping head 555 can concentrate the magnetic field, so that the Hall element is in a strong and uniform magnetic field, thereby more accurately sensing the magnetic field and converting it into an electrical signal to achieve accurate measurement of the measured current.

[0045] The support frame 500 further has a battery block fixedly connected to the inner wall of the bottom side. The battery block is electrically connected with the small motor 51 and the Hall element through wires, for providing power for their operation.

[0046] The battery block is further externally connected with a control switch through wires. The control switch can be wound on the handle 40 when not in use (the wires between the control switch and the battery block can be reserved long enough to avoid disconnection when the length of the telescopic rod 10 is adjusted later). The control switch not only includes the switch of the battery block but also includes the control switch of the small motor, to facilitate the opening or closing of the small motor later.

[0047] The Hall element is further externally connected to the signal collector 20 (such as a plug or a USB connector) through wires. The Hall element transmits the electrical signal converted from the magnetic field to the signal collector 20. The signal collector 20 processes and converts the received electrical signal to be displayed directly on the digital display screen in the form of numbers, presenting the current value in the measured cable to provide a basis for the staff to judge whether the cable is faulty (the wires between the Hall element and the signal collector can be reserved long enough to avoid disconnection when the length of the telescopic rod 20 is adjusted later).

[0048] The embodiment of the present application is actually operated as follows:

[0049] When the line is detected, the wire of the Hall element is firstly inserted into the information collector 20, and then the battery plate and the information collector 20 are turned on; then the length of the telescopic rod 10 is adjusted according to the position of the cable (which can be a certain height or a certain length);

[0050] The limiting bolt 31 can be loosened to appropriately rotate the sleeve 34 to adjust the angle of the handle 40 for the convenience of workers;

[0051] Then the small motor 51 is turned on to drive the transmission shaft 52 to rotate forward or reversely, so that the push rod 53 and the gear plate 54 slide up and down, thereby providing the power for the rotation of the sector gear plate 551, and the driven rod one 552 and the driven rod two 553 can drive the swing rod 554 to swing left and right, thereby clamping the cable between the clamping heads 555;

[0052] Then the Hall element can be used to detect the position of the cable, and the detected data value can be viewed on the signal collector.

[0053] It should be noted that since the cables are of different thicknesses, the size of the clamping head can be changed to use cables of various specifications;

[0054] Moreover, the components in the shell can be made of hard plastic except the small motor and the battery plate, which can not only provide insulation protection but also appropriately reduce the weight (the telescopic rod and the handle can also be made of hard plastic).

[0055] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
