[0043] In this embodiment, the slider base 1 and the slider upper cover 2 are movably connected in the cover plate 3, the slider base 1 and the slider upper cover 2 are provided with a wire clamping port 19 between them and the cover plate 3, the lower ends of the two springs 4 are fixedly connected with the lower inner wall of the cover plate 3, the left and right sides of the upper part of the outer surface of the slider base 1 are provided with a limiting boss 12, a lower limiting surface 13 and an upper limiting surface 14, and the limiting boss 12 is located between the lower limiting surface 13 and the upper limiting surface 14, the limiting boss 12, the lower limiting surface 13 and the upper limiting surface 14 can form limiting with the cylindrical boss 31 respectively.

[0044] Through the above scheme: the lower limit surface 13 on the slider base 1 and the cylindrical boss 31 on the cover plate 3 form a limit, and due to the presence of the limiting boss 12, it cannot move upward in the natural state, forming an upper and lower limit. At this time, the wire clamping port 19 formed between the slider assembly composed of the slider base 1 and the slider upper cover 2 and the cover plate 3 is the largest. When the slider base 1 and the slider upper cover 2 are driven by the manual brake boss 11, the slider assembly composed of the slider base 1 and the slider upper cover 2 moves upward. When the upper limit surface 14 on the slider base 1 and the cylindrical boss 31 on the cover plate 3 form a limit, the slider assembly composed of the slider base 1 and the slider upper cover 2 cannot move upward. At this time, the wire clamping port 19 formed between the slider assembly composed of the slider base 1 and the slider upper cover 2 and the cover plate 3 is the smallest. The upper and lower limiting mechanisms ensure the locking of the slider assembly composed of the slider base 1 and the slider upper cover 2 at a specific position, preventing accidental movement and protecting the internal circuit and user safety.

[0045] In this embodiment, the middle of the front end of the slider base 1 is provided with an NTC fixing groove 18 passing through front and back, and the front end of the slider upper cover 2 is provided with an NTC limiting column 23 corresponding to the position of the NTC fixing groove 18; the cooperation of the NTC limiting column 23 and the NTC fixing groove 18 limits the installation of the NTC temperature acquisition element 5 between the slider base 1 and the slider upper cover 2.

[0046] Through the above scheme: through the cooperation of the NTC fixing groove 18 and the NTC limiting column 23, the NTC temperature acquisition element 5 is limited and fixed, realizing the stable installation of the NTC temperature acquisition element 5, avoiding inaccurate data caused by vibration or external interference, and enhancing the reliability of the overall device.

[0047] In this embodiment, the rear end of the slider upper cover 2 is provided with a wire passing hole 24 passing through front and back.

[0048] In this embodiment, the rear end of the slider base 1 is provided with a cavity 15 on both sides, and the lower part of the cavity 15 is an open structure. The slider base 1 is provided with a buckle groove 17 communicating with the inside of the cavity 15 on both sides. The inner surface of the slider upper cover 2 is provided with a buckle 25 used in cooperation with the buckle groove 17 on both sides. The buckle 25 and the buckle groove 17 are connected to fix the slider base 1 and the slider upper cover 2 together. The spring 4 is located between the slider base 1 and the slider upper cover 2, and the upper end of the spring 4 is fixedly connected with the upper inner wall of the cavity 15.

[0049] Through the above scheme: the compression and release of the slider assembly composed of the slider base 1 and the slider upper cover 2 are controlled by the spring 4, realizing the free adjustment of the size of the wire clamping port 19, which can adapt to different specifications of the measured wire, greatly widening the application range of the device.

[0050] In the embodiment, the slider base 1 is integrally formed with slider positioning columns 16 on both sides of the rear end, and the slider upper cover 2 is provided with slider fixing holes 22 on both sides of the front end for cooperation with the slider positioning columns 16.

[0051] Through the above scheme, the cooperation of the slider positioning columns 16 and the slider fixing holes 22 simplifies the assembly process of the slider base 1 and the slider upper cover 2, and makes the assembly and disassembly of the whole device more convenient and fast, facilitating maintenance and debugging.

[0052] In the use process of the embodiment, the temperature detection structure is arranged on the current detection module, the two modules are designed together, which is beneficial to the monitoring of the electric parameters and temperature, and makes the user more convenient and intelligent. The NTC fixing groove 18 and the NTC limiting column 23 cooperate with each other to limit and fix the NTC temperature acquisition element 5, so that the NTC temperature acquisition element 5 is stably installed. Meanwhile, the cooperation of the slider positioning columns 16 and the slider fixing holes 22 and the cooperation of the buckles 25 and the buckle grooves 17 can fix the slider base 1 and the slider upper cover 2. The cooperation of the slider base 1 and the slider upper cover 2 facilitates the installation of the spring 4 in the cavity 15. The spring 4 is used to compress and release the slider assembly composed of the slider base 1 and the slider upper cover 2. When the spring 4 is in the compressed state, the lower limiting surface 13 on the slider base 1 and the cylindrical boss 31 on the cover plate 3 form a limit. Due to the existence of the limiting boss 12, the slider base 1 cannot move upward in the natural state, forming the upper and lower limits. At this time, the wire clamping port 19 formed between the slider assembly composed of the slider base 1 and the slider upper cover 2 and the cover plate 3 is the largest. When the slider assembly composed of the slider base 1 and the slider upper cover 2 is driven by the manual brake boss 11, the upper limiting surface 14 on the slider base 1 and the cylindrical boss 31 on the cover plate 3 form a limit, so that the slider assembly composed of the slider base 1 and the slider upper cover 2 cannot move upward. At this time, the wire clamping port 19 formed between the slider assembly composed of the slider base 1 and the slider upper cover 2 and the cover plate 3 is the smallest. Therefore, the size of the wire clamping port 19 can be freely adjusted, and it can adapt to different specifications of the measured wire, greatly widening the application range of the device.

[0053] The basic principles and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
