[0051] The locking unit comprises a fixing frame 413 and a screw rod part 414, the fixing frame 413 being rotatably installed between the outer adjusting pipes 41 of the same row and adjacent to each other, the screw rod part 414 being symmetrically rotatably installed at the top of both sides of the fixing frame 413, the outer side of the screw rod part 414 being threadedly connected with a vertical plate 415, the side of the vertical plate 415 close to the outer adjusting pipe 41 being installed with a locking rod 416 and a limiting rod 419, the side of the inner adjusting pipe 43 close to the fixing frame 413 being uniformly provided with a locking groove 418.

[0052] The lower part of the outer adjusting tube 41 near the vertical rod 48 is fixedly connected to the limiting sleeve 412. The vertical rod 48 is slidably connected to the limiting sleeve 412. The bottom of the vertical plate 415 is in contact with the top of the fixing frame 413.

[0055] Example 1: As Figures 4-8 As shown, when a large-scale coarse adjustment is required, the operator reverses the lead screw 414, causing the vertical plate 415 to slide on the outside of the fixed frame 413. The vertical plate 415 causes the limiting rod 419 and the locking rod 416 to move. The limiting rod 419 causes the limiting head 420 to disengage from the limiting groove 422, and the locking rod 416 disengages from the locking groove 418, releasing the limitation on the inner adjusting tube 43.

[0056] At this time, the middle box 2 is pulled up, and the rise of the middle box 2 drives the inner adjusting tube 43 to rise. The inner adjusting tube 43 stretches the first spring 42 and drives the inner rack 44 to rise. The inner rack 44 drives the gear part 46 to rotate. The gear part 46 drives the outer rack 411 to fall. The outer rack 411 drives the vertical rod 48 and the pressure block 49 to fall. The pressure block 49 falls and stretches the second spring 410. The limiting sleeve 412 limits the vertical rod 48 and keeps the vertical rod 48 stable and pressed down until the pressure block 49 presses the ground. The middle box 2 rises to its maximum height. Since the pressure blocks 49 on all sides press down synchronously, the bottom plate 1 is kept horizontally and stably placed, thereby maintaining the verticality of the outer adjusting tube 41 and the inner adjusting tube 43 and reducing the possibility of tilting during the rise.

[0057] After adjustment, the silk rod part 414 is rotated in sequence, so that the vertical plate 415 is adjusted to the pipe 41, the vertical plate 415 drives the limiting rod 419 and the locking rod 416 to move, the limiting head 420 is first clamped in the limiting groove 422, then the vertical plate 415 continues to move and compresses the spring three 421, the locking rod 416 is clamped into the corresponding locking groove 418 through the slot 417, so as to facilitate the positioning of the inner adjusting pipe 43, the height adjustment support stability is maintained, the plurality of fixing frames 413 improve the structural strength, solve the problem that it is inconvenient to fix and lock in time after lifting adjustment, it is difficult to guarantee the verticality and levelness of the scaffold, and the work efficiency is affected.

[0059] The inner bottom surface of the middle box body 2 is symmetrically fixedly installed with telescopic rods 51, the telescopic parts of the telescopic rods 51 are fixedly connected with the bottom of the top plate 3, the inner bottom surface of the middle box body 2 is symmetrically fixedly installed with four servo motors 52, the output ends of the servo motors 52 are fixedly installed with double-head lead screws 53 through speed reducers, the middle outer sides of the double-head lead screws 53 are fixedly connected with center discs 54, the outer rings of the center discs 54 are uniformly provided with positioning holes 55, and the outer lower parts of the double-head lead screws 53 are threadedly connected with lower plates 56.

[0060] The servo motor 52 is installed with a fixed rod 57, the bottom end of the fixed rod 57 is fixedly installed with the middle box body 2, the number of the fixed rod 57 is same as that of the servo motor 52, the lower plate 56 is slidingly connected with the fixed rod 57, the outer side of the fixed rod 57 is sleeved with a spring four 58, the two ends of the spring four 58 are respectively fixedly connected with the bottom of the lower plate 56 and the middle box body 2, the top end of the fixed rod 57 is fixedly connected with a top block 59, the outer upper part of the double-head lead screw 53 is threadedly connected with an upper plate 510, and the bottom side of the top rod 511 is fixedly connected with the upper plate 510.

When the double-ended lead screw 53 rotates, it drives the lower plate 56 to move down and the upper plate 510 to move up. The upper plate 510 drives the top rod 511 to rise. Multiple top rods 511 drive the top plate 3 to rise synchronously. The self-locking of the thread of the double-ended lead screw 53 keeps the height of the top plate 3 infinitely adjustable.

[0063] After adjustment, the operator places a weight on top of the pedal 517. Pressing down the pedal 517 causes the sliding rod 516 and trapezoidal block 519 to press down, compressing the spring 518. The inclined surface of the trapezoidal block 519 presses against the crossbar 512, which in turn moves the locking block 513. The locking block 513 stretches the spring 514 and locks into the positioning hole 55, thus locking the center plate 54 and the double-ended lead screw 53 to prevent unstable rotation of the double-ended lead screw 53.
