Description

Technical Field

[0001] The utility model relates to the technical field of transmission rods for printers, in particular to a transmission rod for printers with an improved structure. Background Art

[0002] A 3D printer, also known as a 3D printer, is a rapid prototyping process that creates a three-dimensional model layer by layer. Its operation is similar to that of a traditional printer, except that traditional printers print ink onto paper to form a two-dimensional plan, while 3D printers stack liquid photosensitive resin materials, molten plastic filaments, gypsum powder and other materials layer by layer through spraying adhesives or extrusion to form a three-dimensional entity. The device is the transmission rod for the printer, specifically the transmission screw.

[0003] When the transmission rod of the printer is in use, it is often used in conjunction with a screw sleeve. As the screw rotates, the screw sleeve cooperates with the screw thread to drive the screw sleeve to move up and down along the screw. The screw and the screw sleeve need to be regularly maintained during use, such as oiling and maintenance, which is mostly manual operation and inconvenient.

[0004] Therefore, a transmission rod for a printer with an improved structure is needed to solve the above problems. Utility Model Content
