[0007] Preferably, limiting blocks are rotatably connected to both side surfaces of the splicing panel adjacent to the T-shaped block, and the limiting blocks rotate to block the ends of the T-shaped slots.

[0008] Further, the limiting block is strip-shaped, one end is rotatably connected, and the other end makes a circular motion to wind around the end of the insertion of the T-shaped block into the T-shaped slot for limiting to prevent it from coming out.

[0009] Preferably, a plurality of first positioning posts are equidistantly connected to the side surface of the splicing panel, and a plurality of second positioning posts are equidistantly connected to the side surface of the cross bar above the base.

[0010] Preferably, two telescopic support rods are arranged between the first positioning post and the second positioning post; both ends of the telescopic support rods are sleeved with the first positioning post and the second positioning post through a collar structure.

[0011] Furthermore, the telescopic support rod is composed of a lead screw and a threaded sleeve, and its length can be freely adjusted as needed and self-locked.

[0012] The beneficial effects of the utility model are as follows:

[0013] The tabletop of the design table designed by this device is a split tabletop, which can be freely combined and spliced by splicing panels, thus realizing modular size adjustment; this device also designs a modular angle adjustment mechanism, which can achieve arbitrary angle adjustment by sleeving two telescopic support rods into different positioning posts; it solves the problem that the size of the existing field workbench is fixed and cannot be adjusted, which is not conducive to carrying, and has the characteristics of simple structure, easy to use, portable disassembly, and carrying.
