[0075] In addition, all parts of the ink coating housing are detachable. The housing 21 is fixedly connected to the tray 22 and the positioning sleeve 11 by screws, and the tray 22 is snapped to the cover 23 by a snap. If the tooling parts are damaged, they can be replaced locally, which is convenient and quick.

[0076] The top surface of the cover 23 is marked with anti-loosening markings to facilitate identification of the anti-loosening markings. The cover 23 and the tray 22 are connected by a snap fastener, making it easy to install and remove the cover 23 when replacing the ink cartridge.

The drive assembly 41 consists of a motor, a reducer, and a lead screw. The lead screw is threadedly connected to the slider 213. The motor drives the lead screw to rotate, and the slider 213 drives the second ink pen 32 to move (the power module 42 is connected to the housing 21 by bolts. The ink application button on the top of the power module 42 is manually pressed to provide power to the tooling. The lead screw of the drive assembly 41 drives the slider 213 and the second ink pen 32 to reciprocate). This achieves the application of anti-loosening marks on the side of the fastener. After the application is completed, the second ink pen 32 returns to its original position.
