[0030] Embodiment 1:

[0031] Figure 1The utility model shows a hand-held inkjet gun provided by the utility model, including an inkjet gun 1 and a buckle 2. The inkjet gun 1 includes a working end face, an inkjet port 11 is arranged on the working end face, and the buckle 2 is detachably connected to the working end face. A through groove 21 is correspondingly arranged on the buckle 2 for exposing the inkjet port 11, so as to facilitate inkjet printing at the inkjet port 11. A pulley 12 and an infrared proximity switch are also arranged on the working end face. The pulley 12 protrudes relative to the buckle 2, which can prevent the product from directly abutting the buckle 2 and avoid sliding friction between the product and the surface of the buckle 2. The infrared proximity switch has For the function of sensing the approach of an object, a through groove is correspondingly provided on the buckle 2 to expose the pulley 12 and the infrared proximity switch. The buckle 2 is connected with a detection roller 3, and an angular momentum sensor is arranged inside the detection roller 3. The angular momentum sensor is electrically connected to the inkjet gun 1. The product needs to abut against the pulley 12 and the detection roller 3 before inkjet coding. When the product moves, the detection roller 3 rotates accordingly due to the sliding friction. At this time, the internal angular momentum sensor feeds back the information to the internal system of the inkjet gun 1, and the inkjet gun 1 controls the inkjet port 11 to output the corresponding characters and codes on the surface of the product.

[0032] The buckle 2 is provided with a power connection pin 22 which cooperates with the power connection port on the working end surface. The buckle 2 is composed of an outer stainless steel plate and an inner circuit wiring. The circuit wiring includes a circuit board. The circuit board has an encoder for auxiliary printing. The circuit wiring is connected to the detection roller 3. The power connection pin 22 is set on the circuit board. The detection roller 3 is electrically connected to the inkjet printer 1 through the circuit wiring and the power connection pin 22. In this embodiment, the power connection pin 22 includes eight pogopins. The cooperation between the power connection pin 22 and the power connection port is a prior art means and is widely used in electronic devices, such as the connection method between Bluetooth headsets and headphone boxes, which will not be elaborated here.

[0033] The power pin 22 can be inserted into the inkjet gun 1 and connected to the circuit structure in the inkjet gun 1, which can not only conduct the circuit but also fix the buckle 2. The buckle 2 has a convex edge. When the buckle 2 is installed on the inkjet gun 1, the convex edge can prevent the buckle 2 from shifting or misaligning. When the buckle 2 is installed on the inkjet gun 1, there is friction between the power pin 22 and the convex edge and the inkjet gun 1, which can prevent the buckle 2 from falling off, which is similar to the connection method between the charging port and the charging cable of various electrical appliances.

[0034] Two positioning baffles 4 are also provided on the buckle 2, and a work station for placing products is formed between the positioning baffles 4. A vertical groove is provided on the positioning baffle 4, and a locking bolt is provided in the groove for fixing the positioning baffle 4 on the buckle 2. Some products are relatively thick, so an extension plate is connected to the adjacent ends of the two positioning baffles 4 to play a better limiting role and prevent the product from shifting or misaligned. The angle between the extension plate and the positioning baffle 4 is 90°. During actual manufacturing, the extension plate and the positioning baffle 4 can be integrally formed to form a right-angle bent plate.

[0035] The inkjet printer 1 in this embodiment has the functions of the inkjet printer in the prior art and can be used alone without the buckle 2.

[0036] Technical principle:

[0037] An improvement is made on the original inkjet gun 1, and a buckle 2 is designed. The buckle 2 can cover the inkjet gun 1. A through groove 21 is provided on the buckle 2 to expose the inkjet port 11 and the pulley 12. The buckle 2 is pre-loaded with a detection roller 3 of a set size. The size of the detection roller 3 can be arbitrarily selected according to product requirements. When the product to be inkjet printed needs to be replaced, the buckle 2 can be manually removed and replaced with another buckle 2 pre-loaded with a detection roller 3 of an adapted size. Various adaptive components can be flexibly pre-loaded on the buckle 2 to facilitate targeted application in different products. This embodiment is mainly aimed at narrow-edge products such as plates and tiles. Two positioning baffles 4 are pre-loaded on the buckle 2. The positioning baffles 4 can limit the deviation of the plate-like product to ensure normal inkjet printing. In actual manufacturing, it is necessary to design multiple buckles 2 corresponding to multiple products.

[0038] Embodiment 2:

[0039] Figure 2-3 A handheld inkjet printer provided by the utility model is shown. The difference between this embodiment and embodiment 1 is that the products targeted are different in appearance. The buckle 2 is equipped with a follower block 5 to replace the positioning baffle 4. Specifically, two follower blocks 5 are sleeved on the detection roller 3, and the follower blocks 5 can rotate together with the detection roller 3. The follower blocks 5 are stepped, and the diameter of the ends of the two follower blocks 5 that are close to each other is smaller than the diameter of the ends that are far away. The sides of the follower blocks 5 are circumferentially provided with tooth grooves. The two follower blocks 5 can abut against the pipe-shaped products. The inner edge of the follower block 5 and the detection roller 3 are matched with a concave-convex structure, so that when the product slides, the follower block 5 can be driven to rotate together with the detection roller 3, so that the angular momentum sensor inside the detection roller 3 plays a role, and cooperates with the inkjet printer 1 to perform precise inkjet printing on the product.

[0040] The inner edge of the follower block 5 is made of rubber material, and the friction between it and the detection roller 3 is relatively large. The user can push the follower block 5 to any position on the detection roller 3 according to actual needs. Then, due to the large friction between the follower block 5 and the detection roller 3, the follower block 5 can be fixed on the detection roller 3.

[0041] This embodiment is mainly applied to products in pipes of different sizes that need to be coded.

[0042] Embodiment 3:

[0043] Figure 4A handheld inkjet printer provided by the utility model is shown. The difference between this embodiment and embodiment 1 is that a laser assistant 6 is mounted on the buckle 2 to replace the positioning baffle 4. Specifically, a functional carrier plate is connected to the side of the buckle 2, and a laser assistant 6 is installed on the functional carrier plate. The laser assistant 6 is electrically connected to the inkjet printer 1, and the laser assistant 6 can assist the user in positioning the product.

[0044] Embodiment 4:

[0045] Figure 5 A handheld inkjet printer provided by the utility model is shown. The difference between this embodiment and embodiment 1 is that a laser scanner 7 is mounted on the buckle 2 to replace the positioning baffle 4. Specifically, a functional carrier board is connected to the side of the buckle 2, and a laser scanner 7 is installed on the functional carrier board. The laser scanner 7 is electrically connected to the inkjet printer 1. The characters, barcodes, numbers and other information scanned by the laser scanner 7 are fed back to the inkjet printer 1. After recognition, the inkjet printer 1 can re-encode the information onto the same product or other products.

[0046] Embodiment 5:

[0047] Figure 6 A handheld inkjet printer provided by the utility model is shown. The difference between this embodiment and embodiment 1 is that the buckle 2 is loaded with a screw 8 and a nut 81 to replace the positioning baffle 4. Specifically, a functional carrier plate is connected to the side of the buckle 2, and a screw 8 is fixed on the functional carrier plate. A nut 81 is threadedly connected to the screw 8. The screw 8 and the nut 81 can cooperate to fix the buckle 2 together with the inkjet printer 1 on a plate preset in the assembly line, which is convenient for assembly line production.
