[0012] Compared with the prior art, a handheld electrical detection equipment protection device using the above technical solution has the following beneficial effects:

[0013] 1. After the electric pen is used, the staff will move the protective cover along the direction from the tip of the electric pen to the handle and put it on the handle of the electric pen. When the protective cover slides on the surface of the handle of the electric pen, the sliding plate will slide on the surface of the handle of the electric pen. When the sliding plate slides, it will pass over the limit ring. In this process, the thickness of the limit ring will push the sliding plate upward to slide inside the sliding groove and compress the spring. When the sliding plate passes over the limit ring, the compressed spring will push the sliding plate in the direction of the central axis of the protective cover, so that the sliding plate can be used to apply a squeezing force to the electric pen to protect the electric pen inside. When the staff installs or removes the protective cover, the process is simple and convenient, which increases the convenience of the protective cover when in use;

[0014] 2. After the staff puts the protective cover on the tip of the electric pen, the staff will put the split tube on the handle of the electric pen, and drive the threaded tube close to the protective cover and screw it into the inside of the protective cover, so that the electric pen can be completely protected inside the protective cover and the split tube. The transparent plate can facilitate the staff to understand the safety of the internal electric pen, thereby increasing the safety of the electric pen;

[0015] 3. When the electric pen is inside the protective cover and the split tube, the tip of the electric pen is inside the stabilizing ring, and the surface of the electric pen handle is squeezed and fits with the elastic strip to fix the position of the electric pen and prevent the electric pen from shaking and colliding inside the protective cover and the split tube, thereby increasing the stability of the electric pen's position inside the protective cover and the split tube.
