Referring to fig. 3, in the present embodiment, an assembly of one locking module 200 and two adjacent showerhead modules 100 is taken as an example for description, and for convenience of description, the two housings 120 of the adjacent showerhead modules 100 are respectively a first housing 120 and a second housing 120. The first clamping portion 126 of the first casing 120 and the second clamping portion 127 of the second casing 120 are clamped and matched, then the spring is sleeved outside the rod body 211 from the end of the rod body 211 where the second inserting portion 212 is not arranged, and the rod body 211 is inserted into the sliding through hole 1251 of the positioning protrusion 125 on the first casing 120 by using the end of the rod body 211 where the second inserting portion 212 is not arranged, and the rod body 211 and the sliding through hole 1251 are slidably matched in the first direction. The second plug part 212 faces the second housing 120, and the second plug part 212 is used for plug-in matching with the corresponding first plug part 128. The spring is clamped between the positioning lug 125 and the second inserting-connecting part 212, then the limiting sleeve 220 is fixed with the rod body 211 in a threaded manner, the spring is in a compressed state, and the spring is used for enabling the second inserting-connecting part 212 to have a sliding trend away from the positioning lug 125 along a first direction; in addition, the position limiting sleeve 220 is located in the second groove 1223, and can be abutted against one side of the positioning protrusion 125 close to the second clamping portion 127 under the elastic force action of the spring, so that the depth of the second insertion portion 212 inserted into the corresponding first insertion portion 128 is limited. That is, the spring serves to make the second socket part 212 have a sliding tendency to approach the second housing 120, so that the second socket part 212 can always be kept inserted into the stopper structure on the second housing 120. In other words, in the initial state, the first clamping portion 126 of the first casing 120 is in clamping fit with the second clamping portion 127 of the second casing 120, and the second insertion portion 212 is always in insertion fit with the first insertion portion 128 of the second casing 120 under the action of the spring. At this time, the locking module 200 is in the first state, and the adjacent head module 100 cannot slide in the second direction. When the position of the adjacent spraying module needs to be adjusted, the limiting sleeve 220 is operated, so that the rod body 211 drives the second insertion part 212 to be far away from the second shell 120 to slide and be separated from the first insertion part 128, at the moment, the locking module 200 is in the second state, the adjacent spraying head module 100 is not locked by the locking module 200, the position can be adjusted in the second direction, and when the position is adjusted to a proper position, at the moment, the second insertion part 212 is loosened, the second insertion part 212 can be inserted into the corresponding first insertion part 128 under the action of the spring, and self-locking is realized. Therefore, the adjacent nozzle modules 100 are convenient to adjust, stable in structure after adjustment is completed, and safe and reliable in use.

It should be noted that in other embodiments, the first mating part 128 may be configured as a protrusion, and correspondingly, the second mating part 212 is configured as a groove.

Referring to fig. 3, it should be understood that, in other embodiments, two guide plates 300 may be slidably connected to the housing 120 of the corresponding head module 100, respectively. Also, each guide plate 300 may be releasably coupled with the corresponding housing 120 by the locking module 200, so that the guide plate 300 and the housing 120 can slide in the second direction when sliding is required, and the corresponding guide plate 300 and the housing 120 are locked by the locking module 200 when sliding is not required. In addition, the guide plate 300 may be provided with a third engaging portion 330 that is engaged with the first engaging portion 126 or the second engaging portion 127 of the head module 100. That is, when the third clamping portion 330 is matched with the first clamping portion 126, the third clamping portion 330 is configured as a groove. When the third engaging portion 330 is engaged with the second engaging portion 127, the third engaging portion 330 is formed as a protrusion, and meanwhile, a threaded hole is formed in the protrusion, a through hole 1275 extending in the third direction is formed in the second side wall 1272 in a penetrating manner, and a screw is screwed with the threaded hole in the protrusion after passing through the through hole 1275, so that the guide plate 300 and the housing 120 are fixed in the second direction. In addition, the third clamping portions 330 on the two guide plates 300 can be different, and can be clamped and matched with the corresponding nozzle module 100.

Referring to fig. 7, each guide plate 300 is a bent plate, specifically, each guide plate 300 includes a first plate portion 310 and a second plate portion 320 which are integrated, the first plate portion 310 and the second plate portion 320 have an included angle different from zero, a third engaging portion 330 is disposed on a side of the first plate portion 310 away from the second plate portion 320, and a side of the second plate portion 320 away from the first plate portion 310 is farther from an ink ejection opening of the head module 100 than the first plate portion 310 in a third direction. The printer is located right above the workpiece to be printed, in the printing process, the second plate portion 320 of the baffle is closer to the workpiece to be printed than the first plate portion 310, and because the second plate portion 320 has an elevation angle relative to the workpiece to be printed, the second plate portion 320 is not easy to interfere with the workpiece to be printed, and can guide the workpiece to be printed to move to the lower side of the ink jetting port, so that the printing is facilitated.

According to the printer provided by the embodiment, the plurality of spray head modules 100 are matched for use, and the positions of the plurality of spray head modules 100 in the second direction can be adjusted as required, so that the plurality of spray head modules 100 can be switched between a linear shape or a step shape, the adjustment is convenient, the application range is wide, the printer is suitable for various printing scenes, and the cost is low; can realize the chromatography ink-jet printing and high-speed printing, and has diversified functions and high efficiency.
