Because the end face of the building board often has process holes or other reserved holes, the sliding blocks 13 and the positioning columns 14 are arranged on the upper limiting plate 9 by combining the structural characteristics of the building board, so that limiting points of the building board are increased, and multi-point limiting is realized. In the same way, a plurality of positioning columns 14 can be arranged on the supporting plate 7 according to the requirement, so that the lifting of the building board is more stable and reliable.
As a preferable structure, as shown in fig. 6 to 7, a first rectangular groove 13-1 penetrating from front to back is provided at an end of the slider 13 hinged to the adjusting bolt 12, the first rectangular groove 13-1 is connected to the second rectangular groove 13-2, and a longitudinal section of the first rectangular groove 13-1 and the second rectangular groove 13-2 after being connected is in a T-shaped structure.

The assembly of the sliding block 13, the adjusting bolt 12 and the upper limiting plate 9 is facilitated.
Based on the above structure, when assembling the slide block 13, the adjusting bolt 12 and the upper limit plate 9, firstly, the adjusting bolt 12 is connected with the threaded hole 9-5 of the upper limit plate 9, the screw cap 12-1 is rotated to adjust the screwing depth of the adjusting bolt 12 in the threaded hole 9-5, and the annular flange 12-3 end of the adjusting bolt 12 extends into the slide block channel 9-4 until the length of the slide block 13 is satisfied; adjusting the adjusting bolt 12 to enable the flat tenon surface to be parallel to the sliding block channel 9-4; then, the second rectangular groove 13-2 of the slider 13 is aligned with the annular flange 12-3 of the adjusting bolt 12, the slider 13 is slowly pushed into the slider channel 9-4, the slider 13 is stopped to be pushed when the circular arc groove 13-3 is coaxial with the adjusting bolt 12, and the nut 12-1 is rotated by a certain angle (the rotation angle is arbitrary, so that the first rectangular groove 13-1 is not parallel to the flat tenon, and the slider 13 slides out).
After the assembly of the slide block 13, the adjusting bolt 12 and the upper limiting plate 9 is completed, the positioning column 14 is installed. When the positioning column 14 is installed, the positioning column 14 passes through the unthreaded hole 9-6 to be fixedly connected with the sliding block 13, and can be connected in a bonding and welding mode.

Of course, in order to facilitate the disassembly of the positioning column 14, a clamping part for connecting with a wrench should be provided on the positioning column 14. For example, a hexagonal hole is provided at the other end of the positioning column 14, and an external hexagonal wrench can be used for assisting in the operation when the positioning column 14 is assembled and disassembled.
One embodiment of the invention: the end cover 5 is fixedly connected with the machine base 2 by adopting screws. Hanging lug plates (hanging parts) connected with the hanging chains 1 are symmetrically welded at the left end and the right end of the machine base 2 respectively; in this embodiment, the transmission rod 3 is directly formed by machining a rod body on a machining center. Two guide posts 7-2 are arranged on a supporting plate 7 in the clamping limiting assembly; and the lower end of the guide post 7-2 is provided with a connecting plate, the connecting plate is connected with the supporting plate through countersunk screws, and a fixing hole corresponding to the guide post 7-2 is arranged at the position of the upper end of the guide post 7-2 corresponding to the rectangular through hole 7-1 of the supporting plate 7. A side limiting plate 15 is welded on one side of the joint of the supporting plate 7 and the lower limiting plate 11. Other structures of this embodiment are substantially the same as the preferred structure, and will not be described here.
Working principle: by rotating the hand wheel 4, the hand wheel 4 drives the transmission rod 3 to rotate, and the two sliding seats 6 move oppositely or reversely along with the rotation of the transmission rod 3, so that the sliding seats 6 can slide relatively to the machine base 2 under the limitation of the machine base 2; the two sliding seats 6 drive the clamping and limiting assembly to finish bearing, clamping and limiting the building board.
Furthermore, in the clamping and limiting assembly, the building board is subjected to bearing and clamping through an upper limiting plate 9 and a lower limiting plate 11 which are connected with the supporting plate 7; because the compression spring 10 is fixedly connected with the supporting plate 7, the compression spring 10 always generates thrust to the upper limiting plate 9, the upper limiting plate 9 slides up and down along the guide post 7-2, and the building board is pressurized and limited through the limiting part 9-1 of the upper limiting plate 9; afterwards, the adjusting bolt 12 is screwed, so that the adjusting bolt 12 pushes the sliding block 13 to slide, and therefore the positioning column 14 is clamped in a hole on the end face of the building board, the effect of multidirectional limiting is achieved, the board is effectively prevented from moving, and the overall practicability is improved.
