[0017] The following is combined with Figure 1-4 This application is described in further detail.

[0018] The embodiment of the present application discloses an inkjet printer, including a handle 1, a support frame 2 is fixed at one end of the handle 1, and the support frame 2 is arranged in a U shape, and the opening of the support frame 2 faces downward, sleeves 7 are arranged on both sides of the inner surface of the support frame 2, and one end of the sleeve 7 is fixedly connected to the support frame 2, and an extension mechanism is arranged at the other end of the sleeve 7, and a connecting block 8 is slidably sleeved on the outer surface of the sleeve 7, a nozzle 3 is fixedly connected between the two groups of connecting blocks 8, and a moving mechanism is arranged on the upper surface of the support frame 2, and the moving mechanism can drive the nozzle 3 to move along the sleeve 7.

[0019] In this embodiment, during use, the user holds the handle 1, places the support frame 2 on the surface of the object to be coded, and uses the other hand to move the nozzle 3 through the moving mechanism, so that the nozzle 3 and the connecting block 8 move along the sleeve 7, thereby preventing the nozzle 3 from shifting during the movement, resulting in the problem of skewed coding pattern.

[0020] Furthermore, the extension mechanism includes a telescopic rod 9 slidably inserted into the sleeve 7, and the end of the telescopic rod 9 away from the sleeve 7 is fixedly connected to a connecting plate 12, and the surface of the connecting plate 12 is fixedly connected to a guide rod 11 arranged parallel to the telescopic rod 9, and the guide rod 11 is slidably inserted into the support frame 2, and fixing bolts 13 are inserted on both sides of the support frame 2, and the fixing bolts 13 are against the surface of the guide rod 11.

[0021] In this embodiment, by providing a telescopic rod 9 and pulling the telescopic rod 9 out of the sleeve 7, the overall length of the sleeve 7 and the telescopic rod 9 can be extended, thereby extending the coding length and improving the applicability of the device. In addition, by providing a fixing bolt 13, the guide rod 11, the connecting plate 12 and the telescopic rod 9 can be limited.

[0022] Furthermore, at least two groups of protrusions 10 are fixedly connected to the surface of the telescopic rod 9 , and the protrusions 10 slide through the sleeve 7 , and the inner surface of the connecting block 8 is provided with an embedding groove adapted to the protrusions 10 .

[0023] In this embodiment, since the telescopic rod 9 is sleeved inside the sleeve 7, there is a height difference between the surface of the telescopic rod 9 and the surface of the sleeve 7. When the connecting block 8 passes through the connection between the sleeve 7 and the telescopic rod 9, shaking will occur. By providing a protrusion 10 to cooperate with the connecting block 8, the height difference between the surface of the telescopic rod 9 and the surface of the sleeve 7 can be compensated, and shaking of the connecting block 8 when passing can be avoided.

[0024] Furthermore, the moving mechanism includes a slide groove 4 opened on the upper surface of the support frame 2, and a slider 5 is slidably connected inside the slide groove 4, the slider 5 is fixedly connected to the nozzle 3, and the side of the slide groove 4 close to the telescopic rod 9 is open.

[0025] In this embodiment, by moving the slider 5 , the slider 5 and the nozzle 3 can be driven to move.

[0026] Furthermore, rollers 6 are rotatably installed at the four corners of the lower surface of the nozzle 3, and the rolling direction of the rollers 6 is consistent with the telescopic direction of the telescopic rod 9. By arranging the rollers 6 at the bottom of the nozzle 3, the movement of the nozzle 3 is facilitated.
