[0012] By adopting the above technical solution, the pull rope is loosened, and the first spring pushes the second rack to slide toward the direction close to the corresponding first rack, thereby realizing the engagement of the second rack and the corresponding first rack; pulling the pull rope, the pull rope pulls the second rack to slide toward the direction away from the corresponding first rack, which helps to disengage the second rack and the corresponding first rack, thereby facilitating the adjustment of the inclination direction and angle of the level body.

At this time, the pull rod pulls the pull rope, which helps to achieve the disengagement of the second rack and the corresponding first rack, thereby facilitating the adjustment of the inclination direction and angle of the spirit level body as needed; the rotating ring is driven to reset by the coil spring, and the rotating ring pushes the pull rod upward, so that the horizontal segment gradually abuts against the pull rod, reducing the pulling force of the pull rod on the pull rope, and providing convenience for the engagement of the second rack with the corresponding first rack.

[0017] Preferably, the rotating assembly includes a sliding rod slidably inserted into the sleeve, a pulling member arranged in the sleeve and an adhesive member arranged on the sleeve, the sliding direction of the sliding rod is parallel to the sliding direction of the adjusting rod, the sliding rod is slidably inserted into the mounting plate, the sliding rod is used to slide relative to the arc segment, when the coil spring is in a natural state, the sliding rod is aligned with the middle of the arc segment, the pulling member is used to pull the sliding rod to slide in a direction away from the mounting plate, and the adhesive member is used to fix the sliding rod and the sleeve relative to each other when the sliding rod abuts against the rotating ring.

[0024] By adopting the above technical solution, the sliding rod corresponding to the sliding rod on the side that needs to be adjusted moves downward, and the sliding rod drives the corresponding transmission block to move downward. Through the bonding cooperation between the fifth Velcro and the sixth Velcro, the limit plate is driven to slide toward the direction close to the mounting plate, so that the third Velcro is bonded to the fourth Velcro. At this time, the limit plate cannot continue to move downward under the restriction of the first telescopic rod, and the sliding rod continues to move downward to separate the fifth Velcro and the sixth Velcro. Then, when the sliding rod drives the rotating ring to rotate, the pull rod in the corresponding sleeve is not easy to move downward due to the bonding action of the third Velcro and the fourth Velcro, so that the position of the sliding rod corresponding to the pull rod can be adjusted to facilitate the adjustment of the inclination direction and angle of the level body.

[0025] In summary, this application has the following beneficial technical effects:

[0026] Confirm the corresponding adjustment group according to the direction that needs to be adjusted, that is, the two adjustment rods in the adjustment group are in the adjustment direction, and then the adjustment rod on the side that needs to be raised in the corresponding adjustment group is fixed relatively to the mounting plate through the fixing assembly, and the remaining adjustment rods are relatively separated from the mounting plate, and then the corresponding lifting member corresponding to the side that needs to be raised is driven to slide in the direction away from the mounting plate. Since the first ball joint between the support rod and the adjustment plate confirms the rotation center of the adjustment plate, the sliding sliding rod can adjust the direction and angle of the adjustment plate at this time, so that the remaining adjustment rods can slide relative to the mounting plate. When the adjustment plate is rotated to the desired direction and angle, all the adjustment rods are fixed relatively to the mounting plate through the fixing assembly, so that the position of the adjustment plate is fixed, which makes it convenient to adjust the inclination direction and angle of the level body according to needs.

At this time, the operating rod 23 drives the sliding rod 21 to move downward, stretching the tension spring 22, and the transmission block 30 on the sliding rod 21 drives the limit plate 26 to approach the abutment block 27 through the adhesion between the fifth Velcro 31 and the sixth Velcro 32, so that the third Velcro 28 and the fourth Velcro 29 are gradually bonded. At this time, the first telescopic rod 47 reaches the longest length, and then the operating rod 23 continues to drive the sliding rod 21 to move downward, so that the fifth Velcro 31 and the sixth Velcro 32 are disengaged, so that the sliding rod 21 gradually abuts against the arc segment 192 When relative sliding occurs, the sliding rod 21 pushes the rotating ring 18 to rotate, causing the arc segment 192 to rotate toward the direction close to the corresponding pull rod 16. At this time, the pull rod 16 corresponding to the sliding rod 21 does not slide under the bonding force of the third Velcro 28 and the fourth Velcro 29, and the second rack 14 can maintain the engagement with the corresponding first rack 13; and the pull rods 16 other than the corresponding sliding rod 21 move toward the direction close to the rotating ring 18 under the pushing action of the second spring 17, and the pull rod 16 pulls the corresponding pull rope 152, and the pull rope 152 pulls the corresponding second rack 14 toward the direction away from the corresponding first rack 13, realizing the disengagement of the second rack 14 and the first rack 13, and then the first Velcro 24 on the moving operating rod 23 is bonded to the second Velcro 25 on the bar hole 44, maintaining the abutment state between the sliding rod 21 and the rotating ring 18, so that the other adjusting rods 6 can slide relative to the sleeve 12.

[0048] Then, use one hand to turn the hand-held ring 34 corresponding to the sliding rod 7 on the side that needs to be adjusted, and use the other hand to lightly support the corresponding sliding rod 7 so that the sliding rod 7 does not rotate with the rotation of the screw 11. At this time, it is necessary to adjust the screw 11 on one side to drive the corresponding sliding rod 7 to slide toward or away from the mounting plate 1. Since both ends of the fixed rod 9 are ball-jointed and the other adjusting rod 6 can slide in the corresponding sleeve 12, the adjusting plate 3 can drive the level body 2 to tilt, thereby adjusting the tilt direction and angle of the level body 2 to the desired position, which is simple and convenient.

[0049] After the adjustment is completed, the operating rod 23 on the adjustment side is pulled to slide in the direction away from the mounting plate 1, so that the first Velcro 24 and the second Velcro 25 are disengaged, and the slide bar 21 slides in the direction away from the rotating ring 18 under the tension of the tension spring 22. Without the abutment of the slide bar 21, the coil spring 20 drives the rotating ring 18 to rotate and reset, so that the arc segment 192 rotates in the direction away from the corresponding pull rod 16, and the arc segment 192 abuts against the pull rod 16 and moves up. The pull rod 16 reduces the tension on the pull rope 152, so that other The second rack 14 corresponding to the sliding rod 7 approaches the first rack 13 under the action of the first spring 151, and the second rack 14 engages with the corresponding first rack 13 to achieve relative fixation of the adjusting rod 6 and the sleeve 12, until the pull rod 16 abuts against the horizontal section 191, and the abutment block 27 on the pull rod 16 abuts against the limit block 46; then the upward sliding rod 21 gradually abuts against the limit plate 26, pushing the limit plate 26 to move upward, so that the fourth Velcro 29 on the limit plate 26 remains disengaged from the corresponding third Velcro 28, which is convenient for the next adjustment.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
