AI Technical Summary
Technical Problem
The existing nozzle adjustment mechanism lacks self-locking capability. The tightening process can easily cause screw misalignment and loosening, resulting in loss of calibration position and affecting the accuracy and quality of the nozzle.
Method used
The nozzle adjustment mechanism uses steel balls and set screws. Through the cooperation of the moving rod and steel balls, the nozzle module is self-lockingly connected to the base plate. The sliding of the steel balls in the groove and the rotation of the threaded rod ensure the stable fixation of the nozzle after calibration.
Benefits of technology
This improves the stability of the printhead after calibration, avoids position loss due to loose screws, and ensures the accuracy and quality requirements of the printhead.

Abstract
This utility model discloses a reversing nozzle adjustment mechanism based on steel balls and set screws, including a base plate and a nozzle module. A mounting plate is provided on the nozzle module, and several connecting mechanisms are provided between the mounting plate and the base plate. Each connecting mechanism includes a first connecting hole and a second connecting hole respectively opened on the mounting plate and the base plate. A common connecting sleeve is movably connected between the first and second connecting holes. A moving rod is slidably connected inside the connecting sleeve, and several steel balls are slidably connected between the moving rod and the connecting sleeve. A threaded tube is provided at the top of the connecting sleeve. By setting the moving rod and steel balls between the base plate and the mounting plate, the user can control the position of the steel balls by controlling the moving distance of the moving rod. This achieves the purpose of self-locking the connection between the base plate and the mounting plate on the nozzle module through the steel balls, thus avoiding the problem of insufficient self-locking after nozzle calibration and easy loss of calibration position in the prior art.
