[0024] As shown in the drawings, Figures 1-4 The support 1 comprises a bottom plate 11, a stand 12, an adjusting assembly 13, a pressing assembly 14 and a foot prop 15, the stand 12 is vertically arranged on the bottom plate 11, the adjusting assembly 13 is arranged on the stand 12, the mounting disc 2 is arranged on the adjusting assembly 13, the height position of the mounting disc is adjusted by the adjusting assembly 13, thereby adapting to artificial wood of different thicknesses. The upper surface of the bottom plate 11 is provided with through fixing grooves 111 near both sides, the pressing assembly 14 is connected with the fixing grooves 111, the artificial wood is fixed on the bottom plate 11 by the pressing assembly 14, and the foot prop 15 is installed on the bottom plate 11. Two groups of pressing assemblies are arranged in each fixing groove 111, and the two groups of pressing assemblies are fixed on both sides of the artificial wood, thereby fixing the artificial wood on the bottom plate 11. In addition, the measuring point position of the artificial wood can be adjusted horizontally by adjusting the position of the pressing assembly 14 in the fixing groove 111.

[0025] In an embodiment, as shown in the drawings, Figures 1-4 The pressing assembly 14 comprises an upper pressing block 141, a lower pressing block 142 and a connecting piece 143, the upper pressing block 141 and the lower pressing block 142 are arranged above and below the bottom plate 11 respectively, and the upper pressing block 141 and the lower pressing block 142 are connected by the connecting piece 143. In use, the upper pressing block 141 is placed at the edge of the artificial wood, the distance between the upper pressing block 141 and the lower pressing block 142 is tightened by the connecting piece 143, thereby fixing the artificial wood on the bottom plate 11.

[0026] In an embodiment, as shown in the drawings, Figures 1-4 The connecting piece 143 is a screw.

[0027] In an embodiment, as shown in the drawings, Figures 1-4 The upper surface of the lower pressing block 142 is provided with a rotation-stopping part 144. Specifically, the rotation-stopping part 144 is a square structure; in use, it is placed in the fixing groove 111, effectively avoiding synchronous rotation of the connecting piece 143 when rotating.

[0028] In an embodiment, as shown in the drawings, Figures 1-4As shown, a magnet 145 is provided on the contact surface between the lower pressure block 142 and the base plate. Preferably, a mounting groove is recessed on the surface of the lower pressure block 142, the magnet 145 is placed in the mounting groove, and the upper surface of the magnet 145 is lower than the upper surface of the lower pressure block 142. Because the upper surface of the lower pressure block 142 is in close contact with the lower surface of the base plate 11 during fixing, the above structure effectively avoids the magnet 145 from being subjected to force.
