Referring to fig. 2, 3 and 4, the drive mechanism includes a slide assembly 6, a lock assembly 7 and an unlock assembly 8. The sliding assembly 6 comprises a wedge block 61, a gear 62 and a rack 63, and the wedge block 61 and the marking rod 5 are connected through a synchronizing rod 64. Wedge 61 is hollow and is set up, and wedge 61 is connected with first spring 611 and telescopic link 612 on keeping away from the one side of steel construction 2, and on telescopic link 612 was located to first spring 611 cover, telescopic link 612 provided direction and spacing for the motion of first spring 611. The first spring 611 and the telescopic rod 612 are obliquely arranged and the oblique direction of the first spring and the telescopic rod is consistent with the direction of the wedge surface of the wedge block 61, the locking assembly 7 is used for fixing the rack 63 in the wedge block 61, and the unlocking assembly 8 is used for unlocking the rack 63, so that the rack 63 slides until the tooth surface of the rack 63 is positioned outside the wedge block 61.
Referring to fig. 2 and 3, the gear 62 rotates synchronously with the wheel 11 through the synchronizing assembly 621, and the wedge block 61 slides away from the steel structure 2 when the gear 62 rotates. An arc-shaped groove 65 used for accommodating the gear 62 is formed at the lowest end of the wedge block 61, a control groove 651 communicated with the interior of the wedge block 61 is formed in the bottom wall of the arc-shaped groove 65, and a control block 66 is arranged in the control groove 651 in a sliding mode. When the gear 62 moves to the arc-shaped slot 65, the control block 66 slides upward. The rack 63 is slidably disposed on the wedge surface of the wedge block 61, and the control block 66 is connected to the rack 63 through a connecting rod 661. The wedge surface of the wedge block 61 is provided with an accommodating groove 67 for the rack 63 to slide, the rack 63 can slide to the tooth surface of the rack 63 through the accommodating groove 67 and is positioned inside the wedge block 61, and the rack 63 can also slide to the tooth surface of the rack 63 through the accommodating groove 67 and is positioned outside the wedge block 61. The wedge block 61 is provided with a second spring 68, and the second spring 68 is used for limiting the rack 63 to keep meshed with the gear 62 when the rack is out of the accommodating groove 67. A fixing plate 69 horizontally arranged is fixedly connected to the inner wall of the wedge block 61, one end of a second spring 68 is fixedly connected to the bottom surface of the fixing plate 69, and the other end of the second spring 68 is fixedly connected to the top surface of the control block 66. The width of the gear 62 is larger than that of the accommodating groove 67, when the tooth surface of the rack 63 is positioned in the wedge block 61, the gear 62 can be contacted with the outer wall of the wedge surface of the wedge block 61, and the possibility that the gear 62 is clamped into the accommodating groove 67 and contacted with the rack 63 is reduced. The degree of depth of arc wall 65 is less than gear 62's radius, and the one end that arc wall 65 is close to rack 63 is the arc setting, and the one end that arc wall 65 is close to rack 63 is crooked with arc wall 65 reverse, has improved wedge 61 towards when being close to steel construction 2 and has slided, and the smoothness nature of gear 62 follow the interior roll-off of arc wall 65. The gear 62, the rack 63 and the control block 66 are made of lightweight plastic, and the second spring 68 has a low stiffness and does not prevent the gear 62 from entering the arc-shaped groove 65.
Referring to fig. 2, the synchronizing assembly 621 includes a first synchronizing wheel 6211, a second synchronizing wheel 6212 and a synchronizing belt 6213, the first synchronizing wheel 6211 is coaxially connected to the rotating shaft of the wheel 11, the second synchronizing wheel 6212 is coaxially connected to the rotating shaft of the gear 62, the synchronizing belt 6213 is simultaneously sleeved on the first synchronizing wheel 6211 and the second synchronizing wheel 6212, and the synchronizing belt 6213 is simultaneously abutted to the peripheral side walls of the first synchronizing wheel 6211 and the second synchronizing wheel 6212. The wheel 11 rotates to drive the first synchronizing wheel 6211 to rotate, and drive the synchronizing belt 6213 to rotate, and drive the second synchronizing wheel 6212 to rotate, so as to drive the gear 62 to rotate synchronously with the wheel 11.
