Through grooves are provided on the tabletop 3 at the positions of the cylinders 5, and the cylinders 5 pass through the corresponding through grooves on the tabletop 3 to achieve the support cooperation between the piston rods of the cylinders 5 and the lower surface of the support plate 7. Metal contact plates 12 are installed at the four corners of the lower surface of the support plate 7 through bolts, and the top end of the push sleeve 8 is in movable support cooperation with the lower surface of the corresponding metal contact plate 12 to ensure that the push sleeve 8 does not directly rub against the support plate 7, thereby ensuring the service life of the support plate 7. Piston rods of the cylinders 5 are all installed with push sleeves 8, and the push sleeves 8 are inserted into the piston rods of the corresponding cylinders 5 and are fixedly connected by bolts to achieve the replacement of the push sleeves 8 after subsequent wear. The top end of the push sleeve 8 is arc-shaped. The central vertical rod 6 passes through the central position of the tabletop 3, the bottom of the central vertical rod 6 is inserted into the sleeve seat 4 and is fixedly connected by bolts, and a sphere 9 is provided at the top end of the central vertical rod 6. A sphere connection seat 10 is provided at the central position of the lower surface of the support plate 7, and the sphere 9 is in movable cooperation with the sphere connection seat 10.

The cover plate 11 is fixedly connected to the sphere connection seat 10 through bolts to limit the sphere 9 in the sphere connection seat 10 and at the same time enable the support plate 7 to tilt with the sphere 9 as the center.

[0023] Installation method and working principle: First, sleeved the pushing sleeve 8 on the piston rod of the cylinder 5 and fasten it with bolts. Install the metal contact plate 12 on the four corners of the lower surface of the support plate 7 with bolts. Vertically install the four cylinders 5 on the upper surface of the bottom plate 1. At the same time, install the bottom of the sleeve seat 4 on the center position of the upper surface of the bottom plate 1 through a flange and bolts. Then connect the two sides of the table top 3 with the side support seats 2 through bolts. At the same time, connect the top of the sleeve seat 4 with the center position of the lower surface of the table top 3 through a flange and bolts. Then put the cover plate 11 on the center vertical rod 6, and insert the sphere 9 at the top of the center vertical rod 6 into the hemispherical groove 14 of the sphere connecting seat 10 on the lower surface of the support plate 7. At the same time, fasten the cover plate 11 with bolts to the bottom of the sphere connecting seat 10. At this time, the sphere 9 is located between the sphere connecting seat 10 and the cover plate 11. Finally, insert the center vertical rod 6 into the sleeve seat 4 and fasten it with bolts to complete the assembly of the base. When 3D printing, if the bottom of the object is inclined, the four cylinders 5 can be coordinated. By controlling the extending length of the piston rods of each cylinder 5, the pushing sleeve 8 abuts against each metal contact plate 12, so that the support plate 7 tilts in the corresponding direction, as Figure 5 shown. Then cooperate with the printer head for printing. The bottom of the printed material is inclined, and the forming direction of the material is perpendicular to the horizontal plane. This base can be used in cooperation with a three-axis printer. The structure of the present invention is reasonable. A sphere connecting seat 10 is arranged at the center position of the lower surface of the support plate 7, a center vertical rod 6 is arranged at the center position of the bottom plate 1, the top of the center vertical rod 6 is rotatably connected with the sphere connecting seat 10 through a sphere 9, and four cylinders 5 are arranged on the upper surface of the bottom plate 1. The four corners of the lower surface of the support plate 7 are respectively supported by the four cylinders 5, so that the support plate 7 can tilt in any direction with the center vertical rod 6 as the center. When printing an oblique object, through the tiltable support plate 7, the object is vertically formed, so that there is no need to print a support, saving the printing cost and improving the printing efficiency at the same time.
