[0021] The trolley base plate 1 is also equipped with a first push rod 12 and a second push rod 13, and the first push rod 12 and the second push rod 13 are respectively connected to two linkage pressure rods 7 through a connecting rod 14.

[0022] The trolley base plate 1 is also equipped with a positioning adjustment block 9, and a positioning post 10 is provided on the positioning adjustment block 9.

[0023] The bottom of the nozzle base plate transition plate 5 is provided with a positioning pin that matches the positioning post 10.

[0024] The first push rod 12 and the second push rod 13 are designed diagonally, thereby realizing the linkage of the four linkage pressure rods 7 to form a rectangular frame.

[0025] The elastic suspension structure 6 includes a connecting column fixedly connected to the arc-shaped guide rail transition plate 3. The top of the connecting column is connected to the nozzle base plate transition plate 5. A spring device is fitted on the connecting column, and the spring device supports the nozzle base plate transition plate.

[0026] Working Principle: A circular guide rail is installed on the base plate of the printing carriage. Two arc-shaped guide rail transition plates are mounted on the guide rail. The printhead base plate is rigidly connected to the printhead base plate transition plates and then to four elastic suspension structures on the arc-shaped guide rail transition plates. Under no external force, the elastic suspension structure must have sufficient elasticity to rebound the weight of the printhead base plate, printhead base plate transition plates, and additional structures such as the printhead, ensuring the printhead base plate is raised a certain distance above the arc-shaped guide rail transition plates. This prevents interference with the positioning posts on the four height pads attached to the carriage base plate along the X or Y axis when the gear motor drives the arc-shaped rack to rotate the arc-shaped guide rail transition plates. Two electric push rods are installed on the carriage base plate. The vertical movement of these electric push rods drives the connecting rod structures on their adjacent sides. On one side, regardless of whether the trolley base plate is rotated to the X-axis or Y-axis by the trolley base plate transition plate and guide rail transition plate, one of the connecting rods will always press down on the nozzle base plate transition plate and compress the elastic suspension structure. This ensures that the positioning pins or locating pins on the back of the nozzle base plate transition plate rigidly align with the three locating posts on the height adjustment plate on the trolley base plate, thus achieving precise and repeatable positioning in the X-axis or Y-axis. Specifically, upon receiving the rotation switching command, the push rod is first released, causing the connecting rod to lift. Under the action of the elastic suspension structure's rebound mechanism, the nozzle base plate, i.e., the nozzle base plate transition plate, springs up, and the three positioning pins on the nozzle base plate transition plate disengage from their corresponding locating posts, becoming airborne. The gear motor is then started, driving the arc gear, which in turn rotates the guide rail transition plate and the nozzle base plate transition plate, along with all the other discs, by 90°. The rotation stops when the plate approaches the locating posts on the three height adjustment plates in the corresponding direction. The push rod is pressed down until it engages with the three corresponding pins on the nozzle base plate transition plate, achieving positioning after rotation. This process is repeated to achieve a 90° switch.

[0027] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
