Therefore, it is necessary to protect and repair electrical equipment. During the maintenance process, workers usually need to use ladders as auxiliary climbing tools.

[0003] After searching, a Chinese patent discloses a circuit safety detection external protection device (Announcement No. CN212296185U), which includes a folding ladder top mechanism and a folding ladder bottom mechanism. The bottom of the folding ladder top mechanism is slidably connected to the top of the folding ladder middle mechanism; the top of the folding ladder bottom mechanism is slidably connected to the bottom of the folding ladder middle mechanism. The ladder body uses the contraction principle to store the folding ladder top mechanism into the folding ladder middle mechanism, and the folding ladder middle mechanism is stored in the folding ladder bottom mechanism for easy carrying, which solves the problem that the ladder body is not easy to store. The patented technology fixes the folding ladder middle mechanism and the folding ladder bottom mechanism through the cooperation of the bayonet spring and the limit hole, and then slides the top telescopic column of the folding ladder top mechanism out of the top telescopic column storage slot of the folding ladder middle mechanism, thereby realizing the telescopic function of the ladder. However, the bottom of the device cannot be adjusted. When the device needs to be placed on an uneven ground, it may cause the lifting center of gravity to be unstable, and then roll over. Therefore, those skilled in the art provide a circuit safety detection device to solve the problems raised in the above background technology. Utility Model Content

The inner ends of the pedals 7 are fixedly connected with springs 8, and the ends of the springs 8 away from the card column 7 are fixedly connected to the inner walls of the adjacent slide grooves b6. Both sides of the middle of the card column 7 are rotatably connected with connecting rods 9. Multiple connecting rods 9 are arranged inside the adjacent slide grooves b6. The ends of the connecting rods 9 away from the card column 7 are fixedly connected with push rods 10. Multiple connecting rods 9 are doubled and penetrate the front and rear ends of the adjacent pedals 2. Multiple push rods 10 are respectively slidably connected to the front and rear ends of the adjacent pedals 2. The bottom end of the left telescopic rod 1 is fixedly connected with an adjusting mechanism, which prevents the sections of the telescopic rod 1 from detaching through the slider a4 sliding inside the adjacent slide groove a3, and pushes the card column 7 to engage with the card groove 5 through the spring 8.

[0029] Reference Figure 1-4 The adjustment mechanism includes two slide grooves c11, which are respectively opened on both sides of the inside of the left telescopic rod 1. The bottom end of the left telescopic rod 1 is rotatably connected with a rotating block 12, and the outside of the rotating block 12 is fixedly connected with a rotating ring 13. The middle part of the rotating block 12 is threadedly connected with a threaded rod 14, and the threaded rod 14 slides inside the lower side of the left telescopic rod 1.

[0030] Working principle: When in use, the telescopic rod 1 is extended by pulling each single section of the telescopic rod 1. When the adjacent slot 5 moves to the column 7, the spring 8 pushes the column 7 to engage with the slot 5, thereby extending the telescopic rod 1. When the telescopic rod 1 is retracted, the push rod 10 is pushed to squeeze the connecting rod 9 to push the column 7 away from the slot 5, thereby shrinking the telescopic rod 1, thereby making the equipment easy to carry; when encountering a bumpy ground, the right telescopic rod 1 is placed at a high place and the left telescopic rod 1 is placed at a low place. The rotating ring 13 is turned to drive the rotating block 12 to rotate and then push the threaded rod 14 to move, thereby achieving height adjustment of the left telescopic rod 1, thereby enabling the equipment to adapt to the bumpy ground and avoid overturning.
