[0038] Figure 1 is a schematic structural view of a handheld printer capable of adjusting the position of an inkjet print head. As Figure 1 shown, the handheld printer capable of adjusting the position of the inkjet print head includes a housing 10 and an ink cartridge sliding assembly. The ink cartridge sliding assembly is movably connected to the housing 10 and can move relative to the housing 10, so that the ink cartridge sliding assembly can adjust the position of the print head 21 according to the printing environment, adapt to different printing environments, and expand the application range of the handheld printer.

[0039] Figure 2 is a schematic structural view of the housing 10 from a perspective. As Figure 2 shown, the housing 10 is generally in the shape of an "L"-shaped structure, and a cavity is provided inside for accommodating the ink cartridge sliding assembly. In Figure 1 the illustrated embodiment, through holes 14 and a pair of rollers 13 are provided at the bottom of the housing 10. The through holes 14 are used for the print head 21 of the ink cartridge sliding assembly to extend or retract from the through holes 14 to adjust the position of the print head 21. In this embodiment, the through holes 14 are located between the rollers 13, so that the print head 21 can extend or retract between the rollers 13. The diameters of both ends of the rollers 13 are larger, and the diameter of the middle part is smaller, forming a structure in which the small ends of two cones are connected. In addition, rubber rings are sleeved on both ends (large ends) of the rollers 13 to prevent the rollers 13 from wearing the components in contact with them during rolling. In addition, a handle 11 and a print button 12 are further provided at the end of the housing 10. The handle 11 protrudes from the housing 10 for the user to hold and use the printer. The print button 12 is provided at the end of the handle 11. When the user holds the handle 11, the user can conveniently press the print button 12 to start a printing operation or release the print button 12 to stop the printing operation.

[0040] Figure 3 is a schematic structural view of the housing 10 from another perspective, Figure 4 is Figure 3 a partial enlarged view of the A position inFigure 3 and Figure 4 As shown in Figure 4 , a catch tooth 15 arranged along the moving direction of the ink cartridge sliding assembly is further provided on the inner side of the housing 10, and the catch tooth 15 faces the ink cartridge sliding assembly to engage with the ink cartridge sliding assembly. In this embodiment, in order to movably connect the ink cartridge sliding assembly, the housing 10 further includes a chute 16 extending along the moving direction of the ink cartridge sliding assembly, so that the moving assembly of the ink cartridge 20 can pass through the chute 16 and the slider 32 (shown in Figure 5 Figure 5 and Figure 6 to be movably connected to the housing 10).

[0041] Figure 5 is a schematic structural diagram of the ink cartridge sliding assembly. As shown in Figure 5 Figure 5 As shown, the ink cartridge sliding assembly includes an ink cartridge 20, a sliding bracket 30, and an unlocking handle 40. The ink cartridge 20 is used to store printing ink and can be an integrated ink cartridge 20 with an integrated print head 21. However, the present application is not limited to the integrated ink cartridge 20, and a split ink cartridge 20 can also be applied through the design of the installation structure of the ink cartridge 20. In this embodiment, a print head 21 is integrally provided at the bottom of the ink cartridge 20 for inkjet printing. An open cavity is provided inside the sliding bracket 30 for installing the ink cartridge 20, and the print head 21 at the bottom of the ink cartridge 20 extends out from the bottom of the sliding bracket 30.

[0042] The sliding bracket 30 is movably connected to the housing 10, the ink cartridge 20 is provided with a print head 21, and the ink cartridge 20 is connected to the sliding bracket 30. When the sliding bracket 30 moves relative to the housing 10, the sliding bracket 30 drives the ink cartridge 20 to move relative to the housing 10 to move the print head 21.

[0043] Figure 6 is a schematic structural diagram of the sliding bracket 30 and the unlocking handle 40. As shown in Figure 5 Figure 5 and Figure 6 As shown, the sliding bracket 30 is provided with a scale 31 extending along the moving direction, and the housing 10 is provided with a triangular mark pointing to the scale 31 to show the moving distance of the sliding bracket 30 relative to the housing 10. At least one side of the sliding bracket 30 is provided with a slider 32 extending along the moving direction. The sliding bracket 30 is movably connected to the housing 10 by embedding the slider 32 into the chute 16 of the housing 10. In this way, the sliding bracket 30 can move relative to the housing 10 by moving the slider 32 along the length direction of the chute 16, and the moving distance is shown by the scale 31 and the mark.

[0044] Figure 7 is a schematic structural diagram of the unlocking handle 40. As shown in Figure 6 Figure 6 and Figure 7As shown, the unlocking handle 40 is rotatably connected to the outside of the sliding bracket 30 and abuts against the housing 10. Specifically, rotating shafts 42 extending in the width direction are provided on both sides of the unlocking handle 40. Correspondingly, the sliding bracket 30 is provided with rotating holes corresponding to the rotating shafts 42. The pair of rotating shafts 42 are inserted into the rotating holes of the sliding bracket 30, so that the unlocking handle 40 is rotatably connected to the sliding bracket 30 through the rotating shafts 42 and the rotating holes and rotates within the space between the sliding bracket 30 and the housing 10.

[0045] In addition, the unlocking handle 40 further includes a clamping portion 41 that extends toward the sliding bracket 30 and is clamped to the clamping teeth 15 of the sliding bracket 30. When the clamping portion 41 is clamped to the sliding bracket 30, the sliding bracket 30 is fixedly connected to the housing 10 through the unlocking handle 40 to lock the sliding bracket 30; when the unlocking handle 40 rotates relative to the sliding bracket 30, the clamping portion 41 disengages from the sliding bracket 30 to unlock the sliding bracket 30. To facilitate the rotation of the unlocking handle 40, the unlocking handle 40 further includes an elastic arm 43. The free end of the elastic arm 43 extends toward the ink cartridge 20 and abuts against the ink cartridge 20 to push the unlocking handle 40 toward the housing 10, so that the clamping teeth 15 are clamped to the housing 10.

[0046] The following combines Figures 8 - 10 to describe the working process of the above-mentioned handheld printer capable of adjusting the position of the inkjet print head.

[0047] Figure 8 is a schematic diagram of the handheld printer printing on a plane. As Figure 8 shown, when printing on a plane is required, the unlocking handle 40 is pressed so that the unlocking handle 40 rotates until the clamping portion 41 disengages from the clamping teeth 15 to unlock the sliding bracket 30. At this time, the elastic arm 43 abuts against the sliding bracket 30 and is in a deformed state.

[0048] Then, the sliding bracket 30 is moved and moved to a suitable position according to the position recorded by the scale 31, so that the print head 21 approaches the printing plane 50. At this time, the print head 21 is flush with the bottom of the roller 13. Then, the unlocking handle 40 is released, so that the unlocking handle 40 rotates in the reverse direction under the restoring force of the elastic arm 43 until the clamping portion 41 of the unlocking handle 40 is clamped into the clamping teeth 15, so that the sliding bracket 30 cannot move in the moving direction and the sliding bracket 30 is locked.

[0049] Finally, the print button 12 is pressed, and the handheld printer performs inkjet printing as the roller 13 rolls.

[0050] Figure 9 is a schematic diagram of the handheld printer printing on the concave surface 52. As Figure 9As shown, when printing on the concave surface 52 is required, the unlocking handle 40 is pressed, causing the unlocking handle 40 to rotate until the engaging portion 41 disengages from the locking teeth 15 to unlock the sliding bracket 30. At this time, the elastic arm 43 abuts against the sliding bracket 30 and is in a deformed state.

[0051] Then, the sliding bracket 30 is moved and adjusted to a proper position according to the position marked by the scale 31, such that the print head 21 extends out from between the rollers 13 to the printing plane 50. At this time, the print head 21 protrudes from the bottom of the rollers 13. Then, the unlocking handle 40 is released, causing the unlocking handle 40 to rotate in the reverse direction under the restoring force of the elastic arm 43 until the engaging portion 41 of the unlocking handle 40 engages into the locking teeth 15, preventing the sliding bracket 30 from moving in the moving direction to lock the sliding bracket 30.

[0052] Finally, the printing button 12 is pressed, and the handheld printer performs inkjet printing as the rollers 13 roll on the auxiliary plane 51.

[0053] Figure 10 is a schematic diagram of the handheld printer printing axially on a convex surface. As Figure 10 shown, when printing axially on the convex surface 53 is required, the unlocking handle 40 is pressed, causing the unlocking handle 40 to rotate until the engaging portion 41 disengages from the locking teeth 15 to unlock the sliding bracket 30. At this time, the elastic arm 43 abuts against the sliding bracket 30 and is in a deformed state.

[0054] Then, the sliding bracket 30 is moved and adjusted to a proper position according to the position marked by the scale 31, such that the height of the print head 21 is lower than that between the rollers 13. At this time, the print head 21 retracts between the rollers 13. Then, the unlocking handle 40 is released, causing the unlocking handle 40 to rotate in the reverse direction under the restoring force of the elastic arm 43 until the engaging portion 41 of the unlocking handle 40 engages into the locking teeth 15, preventing the sliding bracket 30 from moving in the moving direction to lock the sliding bracket 30.

[0055] Finally, the printing button 12 is pressed, and the handheld printer performs inkjet printing as it moves axially along the convex surface as the rollers 13 roll.

[0056] Figure 11 is a schematic diagram of the handheld printer printing circumferentially on a convex surface. As Figure 11 shown, when printing circumferentially on the convex surface 53 is required, the unlocking handle 40 is pressed, causing the unlocking handle 40 to rotate until the engaging portion 41 disengages from the locking teeth 15 to unlock the sliding bracket 30. At this time, the elastic arm 43 abuts against the sliding bracket 30 and is in a deformed state.

[0057] Then, move the sliding bracket 30 and move it to the appropriate position according to the position recorded by the scale 31, so that the height of the print head 21 is lower than between the rollers 13. At this time, the print head 21 shrinks between the rollers 13. Then, release the unlocking handle 40, so that the unlocking handle 40 rotates reversely under the restoring force of the elastic arm 43 until the engaging portion 41 of the unlocking handle 40 is engaged into the teeth 15, so that the sliding bracket 30 cannot move along the moving direction and the sliding bracket 30 is locked.

[0058] Finally, press the print button 12, and the handheld printer moves along the circumferential direction of the convex surface 53 as the rollers 13 roll to perform inkjet printing.

[0059] The above handheld printer with an adjustable inkjet print head position sets the ink cartridge 20 on the sliding bracket 30, and moves the ink cartridge 20 by moving the sliding bracket 30 relative to the housing 10, so that the position of the print head 21 of the ink cartridge 20 can be adjusted to adapt to various environments, especially it can be used for both flat printing and arc surface printing.
