In the process of opening and closing the flip cover 200, the cover opening hook 300 rotates toward the print head assembly 600, at this time, the first spring 700 will be compressed, and when the flip cover 200 is opened or closed, the restoring force of the first spring 700 can enable the cover opening hook 300 to rotate and reset along the rotation axis of the cover opening hook. The restoring force of the cover opening hook 300 is provided by the first spring 700, so that the elastic force of the first spring 700 can be adjusted according to the required cover opening hand feeling, and the elastic force of the printing head assembly 600 is not affected, so that the cover opening force and the printing head pressing force can be simultaneously combined.
Referring to fig. 3, the cover opening hook 300 has a hook portion 310 and a first protrusion 320, and a second groove 330 is disposed between the hook portion 310 and the first protrusion 320, where an opening of the second groove 330 faces a side close to the printing rubber roller 210. Referring to fig. 3 to 5, the first groove 110 and the second groove 330 are formed with a limiting space 800 capable of cooperating with the limiting printing rubber roller 210, and in the process of closing the flip cover 200, the printing rubber roller 210 presses the hooking portion 310 towards the direction of the printhead assembly 600, so that the cover opening hook 300 rotates towards the direction of the printhead assembly 600, the first groove 110 and the second groove 330 generate a notch 810 in the side view direction, the limiting space 800 is opened, and the notch 810 gradually increases along with the gradual rotation of the cover opening hook 300 until the printing rubber roller 210 can be clamped into the limiting space 800 along the notch 810. Then, under the restoring force of the first spring 700, the cover opening hook 300 reversely rotates, the gap 810 between the first groove 110 and the second groove 330 gradually decreases or disappears, the thermal sensitive sheet 610 in the print head assembly 600 presses the printing rubber roller 210 under the elastic force, and presses the printing rubber roller 210 to the side wall of the limiting space 800, so that the printing rubber roller 210 is limited, and the two sets of hooking parts 310 hook the two ends of the printing rubber roller 210, so that the flip cover 200 is kept in a closed state. It should be noted that, as referred to herein, the "in the side view direction" refers to a portion where, when viewed along the axis direction of the printing roller 210, the projections of the first groove 110 and the second groove 330 on the side of the frame 100 overlap, where the overlapping portion is a projection of the limiting space 800, when the flip cover 200 is closed, the projection of the limiting space 800 is a closed or incompletely closed space, and when the space is in an incompletely closed shape, the notch 810 is referred to herein, and as the cover-opening hook 300 rotates, the originally closed space will generate the notch 810 referred to herein, and the notch 810 will also gradually increase, so that the printing roller 210 can be smoothly snapped into the limiting space 800 or separated from the limiting space 800.
With continued reference to fig. 3, the top block 400 is rotatably connected to the frame 100, the top block 400 has a second protrusion 410, the second protrusion 410 extends into the second groove 330 of the cover opening hook 300, the top block 400 is provided with a third groove 420, the first protrusion 320 of the cover opening hook 300 extends into the third groove 420 and can rotate in the third groove 420, in order to facilitate the relative rotation of the first protrusion 320 in the third groove 420, the outer end of the first protrusion 320 is in an arc shape, and the bottom wall of the third groove 420 is also in an arc shape. When the cover opening hook 300 rotates toward the direction of the print head assembly 600, the first protrusion 320 will rotate in the third groove 420 and push the second protrusion 410 upward, so that the second protrusion 410 contacts with the printing rubber roller 210 and pushes the printing rubber roller 210 upward, and under the elastic force of the print head assembly 600, the printing rubber roller 210 is separated from the limiting space 800 from the notch 810, so that the flip cover 200 is opened. Further, with continued reference to fig. 3, a side of the first groove 110, which is far away from the printhead assembly 600, has a first inclined plane 111, a side of the hooking portion 310, which is far away from the printhead assembly 600, has a second inclined plane 331, the first inclined plane 111 and the second inclined plane 331 together form an entrance of a notch 810, and in the process of closing the flip cover 200, the printing rubber roller 210 can press the cover hook 300 along the second inclined plane 331 to rotate the cover hook 300, and the notch 810 is enlarged, and the printing rubber roller 210 is clamped into the limiting space 800 from the notch 810 along the first inclined plane 111.
