[0034] The support plate 7 is arranged on the bracket 1 and can move vertically up and down on the bracket 1 through the vertical displacement component 66. The support plate 7 is provided with a printing platform component 6, including:

[0038] The third rotation drive unit 64 is mounted on the swing frame 63, and the output shaft of the third rotation drive unit 64 is connected to the printing platform 65; through the mutual cooperation between the mobile module 4, the vertical displacement component 66 and the printing platform component 6, the volume is minimized and the space utilization is improved to the maximum extent, and the mobile printing of the printing platform 65 in the five-axis direction is realized;

[0039] The first rotation driving unit 61 is a first motor, and the first motor drives the swing frame 63 to swing around the Z axis;

[0040] The second rotation driving unit 62 is a right-angle reducer, which drives the swing frame 63 to rotate about an arbitrary straight line in the horizontal plane as an axis;

[0041] The third rotation driving unit 64 is a second motor, and the second motor drives the printing platform 65 to rotate around its own axis.

[0042] The vertical displacement assembly 66 includes:

[0043] The third motor 661 is connected to the bottom of the bracket 1, and its driving shaft is connected to a vertically arranged screw rod 662;

[0045] The outer side of the screw 662 is provided with a light rod 664; the screw 662 is driven to rotate by the rotation of the third motor 661, and the screw 662 drives the nut pair 82 to move upward, thereby driving the entire printing platform assembly 6 to move up and down, and cooperate with the nozzle 5 to print.

[0046] The swing frame 63 is an L-shaped structure, one right-angle side of which is connected to the right-angle reducer, and the other right-angle side is connected to the second motor, and the swing frame 63 is driven to swing through the right-angle reducer.

[0047] A rubber base 3 is provided at the bottom of the bracket 1 .
