A toggle block 29 is fixedly installed at the lower end of the slider 26. The movable clips 28 and the fixing clips 23 are respectively clamped between the clamping plate 21.

[0022] The specific settings and effects of the embodiment are described below. When installing the overvoltage protector 15, first, the overvoltage protector 15 is connected with the fixing plate 22 through the screw 24, then the two fixing clamps 23 above the fixing plate 22 are buckled at the clamping plate 21 above the guide rail 2, and then the sliding block 26 is pulled down along the sliding groove 25 by the pulling block 29. In the process, the spring 27 will be stretched and deformed, until the movable clamp 28 below the sliding block 26 is buckled at the clamping plate 21 below the guide rail 2. At this time, the pulling of the pulling block 29 is released, and the spring 27 will reset. However, due to the limiting of the movable clamp 28, the movable clamp 28 and the fixed clamp 23 will firmly fix the fixing plate 22 and the overvoltage protector 15 on the guide rail 2, making the installation convenient and fast. The spacing between the movable clamp 28 and the fixed clamp 23 is adjustable, so that the fixing plate 22 can be fixed on guide rails 2 of different specifications and sizes, and the device has higher practicality.

One side of the lower end of the transparent protective cover 11 is fixedly installed with the handle 12.

[0024] The effect achieved by the whole embodiment is that by improving the guide rail 2, the clamping plates 21 are arranged above and below one end of the guide rail 2, which are matched with the fixed clamps 23 and the movable clamps 28 of the fixed plate 22, so that the user can conveniently install the overvoltage protector 15. When the overvoltage protector 15 is installed, the overvoltage protector 15 is connected with the fixed plate 22 through the screw 24, then the two fixed clamps 23 above the fixed plate 22 are buckled at the clamping plates 21 above the guide rail 2, then the sliding block 26 is pulled along the sliding groove 25 by the pulling block 29 and moves downward, in the process, the spring 27 will be stretched and deformed, until the movable clamp 28 below the sliding block 26 is buckled at the clamping plate 21 below the guide rail 2, at this time, the pulling of the pulling block 29 is released, the spring 27 will reset, but due to the limiting of the movable clamp 28, the fixed plate 22 and the overvoltage protector 15 are firmly fixed on the guide rail 2 by the fixed clamps 23 and the movable clamps 28, so that the installation becomes convenient and fast, the spacing between the movable clamp 28 and the fixed clamp 23 is adjustable, so that the fixed plate 22 can be fixed on guide rails 2 of different specifications and sizes, so that the device has higher practicality. When the overvoltage protector 15 is disassembled and repaired, only the pulling block 29 is pulled downward to drive the sliding block 26 and the movable clamps 28 on both sides to move downward, until the clamping plate 21 below the guide rail 2 is cancelled, the bottom of the whole fixed plate 22 and the overvoltage protector 15 can be pulled outward, and then it can be disassembled by pulling it upward.
