[0002] 3D printer, also known as three-dimensional stereo printer, is a high-tech rapid prototyping equipment. It uses a layer-by-layer stacking method to stack liquid photosensitive resin, molten plastic filament, gypsum powder and other materials by spraying binder or extrusion to form a three-dimensional entity. Its working principle is similar to that of a traditional printer, but the difference is that traditional printers print two-dimensional graphics on paper, while 3D printers build three-dimensional objects. 3D printing technology has been widely used in many fields such as jewelry, footwear, industrial design, architecture, automobiles, aerospace, and medical care. In the medical field, 3D printing technology has realized the manufacture of porous titanium bone implant prostheses, providing patients with more accurate treatment plans. At the same time, 3D printing technology has also shown its advantages in the field of architecture, and can quickly produce exquisite architectural models that meet design requirements. With the continuous development and popularization of 3D printing technology, more and more consumers and companies have begun to pay attention to and use 3D printers. 3D printing technology not only improves production efficiency and reduces costs, but also provides more possibilities for innovation and personalized customization.

[0003] After searching, a Chinese patent with announcement number CN220297839U discloses a 3D printing device that is convenient for replacing a print head, including a base, first slide grooves are respectively opened on both sides of the upper side wall of the base, an auxiliary guide rod is fixedly connected between the front and rear side walls of one of the first slide grooves, a first screw rod is rotatably connected between the front and rear side walls of the other first slide groove, an auxiliary slider is slidably connected to the auxiliary guide rod, a first moving block is threadedly connected to the first screw, a first servo motor is installed on the rear side wall of the base, an output shaft end of the first servo motor extends into the first slide groove and is fixedly connected to one end of the first screw A gantry is fixedly connected between the auxiliary sliding block and the upper side wall of the first moving block, and second sliding grooves are opened on both side walls of the gantry, and a second moving block is slidably connected in the second sliding grooves, a second servo motor is installed on one side wall of the second moving blocks, an output shaft end of the second servo motor passes through the second moving block and is fixedly connected to a second screw, the other end of the second screw is threadedly passed through a third moving block and is rotatably connected to another second moving block, a third servo motor is installed on the upper outer wall of the gantry, and an output shaft end of the third servo motor extends to one of the second sliding grooves and is fixedly connected to a third screw.

[0004] Although the 3D printing device in the above-mentioned prior art can realize the rapid disassembly, assembly and replacement of the print head of the 3D printing component by disassembling and assembling the components, in actual operation, when disassembling the print head of the printing component, it is necessary to simultaneously detent the two control panels on both sides of the lower end of the mounting plate, and at the same time, the print head needs to be pulled down and removed from the plug slot of the mounting plate, which makes the operation still not convenient enough. In addition, the printing device is generally placed directly on a workbench or operating table during use. Since it is not fixed, it is also easy to be touched, resulting in the risk of the device falling and being damaged. In particular, the gantry on the device has a certain height, and it is easy to be scratched if not careful, causing the device to fall. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] Firstly, in the present invention, the printing component body is inserted into the mounting seat limit groove of the moving part of the X-axis screw module through the connecting block on the back side. During the insertion process, the lower end of the connecting block squeezes the inclined surface of the card block extending out of the limit groove, and at the same time, the limit plate connected to the card block slides in the mounting cavity to compress the first spring sleeved on the outer side of the pull rod. When the connecting block is inserted, and the external card groove corresponds to the position of the card block, the first spring elastically resets and pushes the card block connected to the limit plate to be inserted into the card groove of the connecting block, so that the fixing and use of the printing component body can be completed. When disassembling and replacing, only one hand needs to pull the handle so that the handle drives the pull rod to drag the limit plate to move in the mounting cavity. When the card block on the limit plate is separated from the card groove on the connecting block, the printing component body can be taken out of the limit groove from bottom to top at the mounting seat position, thereby making the disassembly and assembly more convenient.

[0020] Secondly, in the present invention, the mounting shell is fixed on both sides of the base, and the operating handle is pressed, so that the handle slides downward at the mounting shell through the slide bar, and at the same time, the lower end of the slide bar pushes the mounting plate to slide down, and the suction cup at the matching plate at the lower end of the mounting plate can extend through the through hole to be sucked tightly with the placement surface of the external base, so that the base is reinforced, thereby effectively avoiding the risk of the device falling and being damaged due to accidental touching of the device;

[0021] Thirdly, in the present invention, the mounting shell is inserted along the front limit of the base. During the insertion process, the corners on both sides of the front of the base squeeze the inclined surfaces of the bevel block, so that the stopper connected to the bevel block slides in the connecting sleeve and squeezes the second spring on the outside of the round rod until the mounting shell is inserted into place and the snap-in end of the bevel block corresponds to the limiting groove on the outside of the base. At this time, the second spring resets and pushes the snap-in end of the bevel block connected to the stopper to be snapped and fixed. In subsequent use, if the suction cup needs to be cleaned or replaced, the pull button can be pulled to drive the stopper to slide in the connecting sleeve through the round rod. When the bevel block on the stopper is separated from the limiting groove, the mounting shell can be moved from the back to the front at the base, so that the mounting shell part of the reinforcement mechanism can be quickly disassembled and assembled on the outside of the base for use.

[0044] The working principle of the present invention is as follows: during use, when installing the printing component body 4, the printing component body 4 is inserted into the limiting groove 11 of the mounting seat 8 of the moving part of the X-axis screw module 3 through the connecting block 9 on the back. During the insertion process, the lower end of the connecting block 9 squeezes the inclined surface of the card block 706 extending out of the limiting groove 11, and at the same time, the limiting plate 705 connected to the card block 706 slides in the installation cavity 702 to compress the first spring 703 sleeved on the outer side of the pull rod 701. When the connecting block 9 is inserted and the external card slot 10 is positioned with the card block 706, the first spring 703 is compressed. Corresponding to the position, at this time, the first spring 703 elastically resets and pushes the block 706 connected to the limit plate 705 to be inserted into the slot 10 of the connecting block 9, so that the printing component body 4 can be fixed and used. When disassembling and replacing, it is only necessary to pull the handle 704 with one hand, so that the handle 704 drives the pull rod 701 to drag the limit plate 705 to move in the installation cavity 702. When the block 706 on the limit plate 705 is separated from the slot 10 on the connecting block 9, the printing component body 4 can be taken out from the limit slot 11 from bottom to top at the position of the mounting seat 8;

[0045] On the basis of the mounting shell 501 being limited and fixed on both sides of the base 1, the handle 507 is pressed so that the handle 507 slides downward on the mounting shell 501 through the slide bar 506. At the same time, the lower end of the slide bar 506 pushes the mounting plate 502 to slide down, and the suction cup 504 at the matching plate 503 at the lower end of the mounting plate 502 can extend through the through hole 505 to be sucked tightly with the placement surface of the external base 1, so that it is reinforced to the base 1. When the mounting shell 501 is quickly limited and fixed on the base 1, the mounting shell 501 is inserted along the front side of the base 1. During the insertion process, the corners on both sides of the front side of the base 1 squeeze the inclined surface of the bevel block 263, so that the stopper 262 connected to the bevel block 263 is connected The second spring 267 on the outside of the round rod 265 is pressed against the connecting sleeve 261 until the mounting shell 501 is inserted into place and the snap-in end of the bevel block 263 corresponds to the limiting groove 264 on the outside of the base 1. At this time, the second spring 267 is reset to push the snap-in end of the bevel block 263 connected to the stopper 262 to be snapped in and fixed. In subsequent use, if the suction cup 504 needs to be cleaned or replaced, the pull button 266 can be pulled so that the pull button 266 drives the stopper 262 to slide in the connecting sleeve 261 through the round rod 265. When the bevel block 263 on the stopper 262 is separated from the limiting groove 264, the mounting shell 501 can be moved out from the back to the front on the base 1.
