The bellows 309 is used to protect the rotating sleeve 302.

[0025] The lower surface of the first rotating sleeve 302 is in contact with the upper surface of the clamping groove rotating block 301.

[0026] The working principle of this embodiment is as follows: When using this kind of easily adjustable electrical instrument, rotate the first adjusting mechanism 3 to the vertical position. Rotate the first rotating sleeve 302 through the convex points on the outer surface of the first rotating sleeve 302, so that the second rotating sleeve 303 moves outward, and the rotating shaft column 305 moves outward through the first threaded column 304.

At this time, continue to rotate the first rotating sleeve 302 so that the through-hole rotating ring 306 continues to move downward, and push the ball head rotating rod 307 to move downward, thereby pushing the groove rotating block 308 to rotate on the outer surface of the rotating shaft of the rotating shaft column 305, and then clamp the ground through the inclined surface of the groove rotating block 308 to realize the adjustment and support of the electrical instrument, which is convenient for the operation and use of the operator.

[0028] The rectangular column 604 is fixedly connected to the lower surface of the box body 1. The upper surface of the rectangular column 604 is in contact with the lower surface of the bottom plate 610. The upper surface of the rectangular frame 607 is in contact with the lower surface of the bottom plate 610. The card slot frame 609 is clamped to the box body 1. The friction plate 608 is used to limit the rough surface column one 601 and the rough surface column two 603. The outer surface of the rough surface column two 603 is fixedly connected to the outer surface of the symmetrically arranged card slot rotating block 301, and the rough surface column one 601 and the rough surface column two 603 are limited by the limit rotating shaft 602, so that when they are in contact with the friction plate 608, the rough surface column one 601 and the rough surface column two 603 will not bend. While the bottom plate 610 protects the locking mechanism 6, the arc corners of the bottom plate 610 are used to process the rough surface column one 601 and the rough surface column two 603, so that no debris remains.

[0029] The adjusting mechanism two 7 includes a wedge block one 701. The outer surface of the wedge block one 701 is fixedly connected to the outer surface of the rectangular frame 607. A sliding rod 702 and a spring 703 are slidably connected inside the lower rib plate 2. A slider 704 is fixedly connected to the outer surface of the sliding rod 702. A wedge block two 705 is arranged on the outer surface of the slider 704. The sliding rod 702 is used to limit the adjusting mechanism one 3.

[0030] The adjusting mechanism two 7 further includes a magnetic plate one 706. The box cover 4 is fixedly connected to the magnetic plate one 706. A connecting rod 708 and a bellows two 707 are fixedly connected to the outer surface of the upper rib plate 5. A through-hole column 709 is slidably connected to the outer surface of the connecting rod 708. A threaded column two 710 is threadedly connected inside the through-hole column 709. A magnetic plate two 711 is fixedly connected inside the through-hole column 709. The magnetic plate one 706 and the magnetic plate two 711 are used to fix the through-hole column 709.

[0031] The upper surface of the spring 703 is fixedly connected to the outer surface of the slider 704. The outer surface of the bellows two 707 is fixedly connected to the outer surface of the through-hole column 709. The outer surface of the through-hole column 709 is in contact with the outer surface of the box cover 4. The threaded column two 710 is used to support the box cover 4. When the hydraulic pump 605 pushes the friction plate 608, it cannot push the wedge block one 701. When pushing the wedge block one 701, it cannot push the friction plate 608, so as to ensure the stability of the adjustment and support of the electrical instrument and the stability of the results of the unused electrical instrument.

[0032] The working principle of this embodiment is as follows: When using this kind of easily adjustable electrical instrument, when adjusting the level of the box body 1, the hydraulic pump 605 pushes the clamping plate 606 to move outward, drives the rectangular frame 607 to move outward, makes the friction plate 608 contact with the outer surface of the rough surface column two 603, realizes the angle fixation of the first adjusting mechanism 3, and realizes the fixation of any angle of the first adjusting mechanism 3 through this angle fixation. Through the cooperation of the symmetrically arranged locking mechanism 6 and the first adjusting mechanism 3, and through the corresponding setting and separate adjustment of the locking mechanism 6 and the first adjusting mechanism 3, the fixation of different angles of the four symmetrically arranged first adjusting mechanisms 3 is realized, increasing the adaptability to different ground surfaces. After adjusting and supporting the box body 1, at this time, rotate the through-hole column 709 so that the through-hole column 709 is perpendicular to the box cover 4 and slide on the outer surface of its connecting rod 708. At this time, rotate the second threaded column 710 to make the second threaded column 710 extend out and contact the ground to assist in supporting the box cover 4, thereby forming an additional working surface, which is convenient for the operator to adjust the electrical instrument. After the use is completed, the first adjusting mechanism 3 resets. At this time, the hydraulic pump 605 drives the rectangular frame 607 to retract, and reversely pushes the first wedge block 701 to squeeze the slider 704, so that the sliding rod 702 slides inside the lower rib plate 2, and the first adjusting mechanism 3 is limited by the symmetrically arranged locking mechanism 6, the first wedge block 701, and the second wedge block 705 to realize its fixation, ensuring the stability of the electrical instrument when not in use. And when in use, while the hydraulic pump 605 pushes the friction plate 608, the contact between the first wedge block 701 and the slider 704 is released, and the sliding rod 702 is pushed by the spring 703, so that the first adjusting mechanism 3 can rotate normally.
