After the separating rod is pulled by applying external force, the elastic force of the spring can be overcome to enable the positioning block to move downwards. After the ball moves downwards along with the positioning block, the ball is separated from the positioning notch. At this time, the substrate can rotate relative to the base plate.
Once the position of the substrate is determined, after the external force is stopped, the ball is embedded in the positioning notch again under the action of the elastic force of the spring, and the substrate and the bottom plate are repositioned together.
In the above-described frame of the printer, the upper portion of the bottom plate has a projecting extension portion, and the positioning hole portion is located at the extension portion.
In the above-mentioned frame of the printer, the extension part and the bottom plate are of an integrated structure.
The length of the positioning hole is increased due to the arrangement of the extension part, and the positioning block and the spring can be stably arranged in the positioning hole.
Compared with the prior art, the frame of this printer is because the effect infrabasal plate is in the same place with the stable location link of bottom plate in locking structure, consequently, can not rotate in the printer normal use, and its stability is higher.
Meanwhile, when the printer needs to be rotated, external force is applied to enable the locking structure to be in a separated state, at the moment, the substrate can stably rotate relative to the bottom plate, and the printer on the substrate can rotate along with the substrate, so that the applicability of the printer is high.
In addition, the locking structure is positioned between the base plate and the bottom plate, and the whole rack structure is compact and has high practical value.
