The control component is electrically connected to the linear motor 211, the telescopic cylinder 2121, and the thread cutting cylinder 232 for driving the sliding part 21, the clamping part 22 and the thread cutting part 23 to move respectively.

[0032] When a safety protection device for electrical construction is used, the height of the device is adjusted by rotating the worm 122, and then the device is pushed to a suitable position through the fixed universal wheel 111 so that the device covers the electrical box 3, and then the cables connected to the electrical components in the electrical box 3 are clamped one by one using multiple clamping parts 22, and then the measuring ring of the leakage detector 24 is opened, and the cable is placed therein, and then the leakage detector 24 detects in real time whether the corresponding cable is leaking. Once a leakage cable is found, the leakage detector 24 will send a signal to the control component, and then the control component starts the linear motor 211 to move the wire cutting frame 234 to the bottom of the leakage cable. Then start the telescopic cylinder 2121 to lock and fix the position of the linear motor 211, then start the wire cutting cylinder 232, raise the wire cutting frame 234, raise the side rack 237, and cut the leaking cable. This arrangement can cut off the line where the leaking cable is located in time, and at the same time enable workers to quickly find the leaking cable, deal with and replace it in time, thereby reducing the safety hazards of workers during construction. Pull down the spring roller shutter 131, and at the same time pull down the lock bolt 134, put the pull rod end corresponding to the spring roller shutter 131 into the U-shaped lock buckle 133, and then release the lock bolt 134. The spring roller shutter 131 can perform daily protection on the electrical box 3 to reduce the entry of dust and rainwater.
