At the moment, the force applied by the spring to the universal ball rod pressing block is increased, and pressure exists between the printing platform and the printing screen, so that absolute parallelism between the printing platform and the printing screen is ensured. At this time, the screw stops rotating.
Finally, the fastening screw can be locked by one hand, and the opening structure of the universal ball head rod fixing piece firmly clamps the universal ball head rod. At this point, the leveling action is completed.
Compared with the prior art, the invention has the advantages that: when the printing platform is in a loose state, any degree of freedom is open, and adjustment of any angle can be performed. When leveling, the printing platform is pressed on the printing screen by utilizing the elasticity of the spring, so that the uniform stress is ensured, the printing platform and the printing screen are absolutely parallel, and then the leveling operation can be easily completed by locking the fastening screw.
