[0009] Preferably, as an improvement, a wire nose is sleeved on the probe stage between the fastener and the fixing plate, the wire nose is in contact with the probe conductor, and the end of the wire is crimped in the wire nose.

[0010] The principle of the scheme is: in the actual aluminum electrolysis production scene, the environment is complex and there is a certain safety risk, and the workers need to hold the handle rod to carry out detection work. Thanks to the carefully designed operating structure of the device which keeps a safe distance from the electrolysis equipment, it can effectively avoid the workers from close contact with the electrolysis equipment, thereby ensuring the workers to carry out detection work in a safe area. Among them, the probe layout on the fixing plate and the unique bending structure of the fixing plate are the key to realize multi-angle detection. The left and right side connecting pieces of the fixing plate are bent by 135°, thereby forming a stable support part, and at least two vertical and side-by-side mounting hole positions are provided on each support part, which are used to connect the probes. In this way, the probes can accurately detect the equal distance voltage drop of different parts such as anode guide rod and busbar according to different detection needs. In addition, the fixing plate and the end of the handle rod are connected through a specific rotating connection structure. Specifically, the connecting piece is two ear plates fixedly connected to the fixing plate, the ear plates are provided with ear holes, and the connecting seat on the sleeve pipe of the handle rod end is provided with two connecting plates provided with through holes. By accurately passing the pin shaft through the ear hole and the through hole, the rotating connection between the two is realized. This ingenious design enables the fixing plate to rotate flexibly, regardless of the complexity of the structure of the electrolysis equipment, it can ensure that the probes stably contact the parts to be detected of the electrolysis equipment, greatly improving the accuracy and reliability of the detection.

[0011] The measuring instrument is detachably connected in the middle of the handle rod through the instrument seat. The design of the instrument seat is extremely ingenious. The seat pipe is tightly sleeved on the handle rod, and the T-shaped insertion slot is formed on the seat plate, and the T-shaped insertion plate on the back of the measuring instrument can be smoothly inserted into the T-shaped insertion slot. This connection method has many advantages. On the one hand, it is convenient to install the measuring instrument near the worker's hand-held end, so that the worker can clearly and accurately read the detection data without much effort. On the other hand, the worker does not need to spend extra effort to support the measuring instrument, which greatly simplifies the detection operation process, saves operation time, and thus improves the detection efficiency. In addition, the measuring instrument and the probe can be conveniently detached from the handle rod, which meets the needs of separate use in some special cases, such as using the probe and the measuring instrument separately for fine detection, which further expands the use scenarios of the device and enhances the flexibility of use, making it can adapt to more diversified work needs.

[0014] 2. Reliable operation: From the perspective of the connection structure, whether it is the rotating connection between the fixed plate and the handle, the detachable connection between the measuring instrument and the handle, or the connection between the probe and the fixed plate, mature and stable connection methods are adopted, such as pin connection, T-slot connection and fastener fixation, to ensure that there will be no loosening or falling off during the testing process, which will affect the test results and guarantee the accuracy and stability of the test data.

[0015] 3. Easy to use: Workers can operate the device simply by holding the lever, without the need for complex training or professional skills. The lever is ergonomically designed for easy gripping; the measuring instrument is mounted close to the hand for easy reading; the mounting plate can rotate flexibly to adapt to different testing positions, making operation simple and quick, and greatly improving the work efficiency of operators.
