Communication grooves 7 are provided on the front and rear sides of the top of the base 1. The inner wall of the communication groove 7 is movably connected to a support plate 8. The top of the support plate 8 is fixedly connected to the bottom of the support plate 2. A linkage mechanism 9 is provided inside the base 1, and a transmission mechanism 10 is provided at the rear side of the base 1

[0025] Referring to Figure 3 , the linkage mechanism 9 includes a movable groove 91. The movable groove 91 communicates with the communication groove 7. The bottom of the support plate 8 is fixedly connected to a first triangular plate 92. The two first triangular plates 92 are symmetrically arranged.

[0026] As a technical optimization solution of the present utility model, by providing a linkage mechanism 9, moving two movable blocks 93 can drive two second triangular plates 94 to approach each other. Since the top of the second triangular plate 94 is in contact with the bottom of the first triangular plate 92, the movement of the second triangular plate 94 can successively drive the first triangular plate 92, the support plate 8 and the support plate 2 to move upward.

[0027] Reference Figure 3 , the transmission mechanism 10 includes a driven gear 101, a transmission rod 102 and a bidirectional lead screw 103.

[0028] As a technical optimization solution of the present utility model, by providing a transmission mechanism 10, rotating the driven gear 101 can drive the transmission rod 102 to rotate. The rotation of the transmission rod 102 can drive the bidirectional lead screw 103 to rotate. The rotation of the bidirectional lead screw 103 can drive two movable blocks 93 to move and approach each other.

[0029] Reference Figure 4 , on the left side of the rear side of the base 1, an installation groove 11 is opened. The bottom of the inner wall of the installation groove 11 is fixedly installed with a servo motor 12. The servo motor 12 is electrically connected to the computer 3 through a wire. The output end of the servo motor 12 is fixedly installed with a driving gear 13. The surface of the driving gear 13 meshes with the surface of the driven gear 101.

[0030] As a technical optimization solution of the present utility model, by providing the installation groove 11, the servo motor 12 and the driving gear 13, the installation groove 11 can fix and limit the servo motor 12. Starting the servo motor 12 through the computer 3 can make the output end of the servo motor 12 drive the driving gear 13 to rotate. Since the driving gear 13 meshes with the driven gear 101, the rotation of the driving gear 13 can drive the driven gear 101, the transmission rod 102 and the bidirectional lead screw 103 to rotate.

[0031] Reference Figure 3 , the bottom of the movable block 93 is fixedly connected with a sliding block 14. A sliding groove 15 is opened at the bottom of the inner wall of the movable groove 91. The surface of the sliding block 14 is slidably connected to the inner wall of the sliding groove 15.

[0032] As a technical optimization solution of the present utility model, by providing a sliding block 14 and a sliding groove 15, the forward and backward movement of the movable block 93 can drive the sliding block 14 to slide back and forth inside the sliding groove 15. The sliding groove 15 can limit the sliding block 14 and the movable block 93 in the up, down, left, and right directions, thereby improving the stability of the movement of the movable block 93 and the second triangular plate 94.

[0033] Reference Figure 1 , four sliding rods 16 are fixedly connected to the top of the base 1. The four sliding rods 16 are arranged in a rectangle. Both the left and right sides of the support plate 2 are fixedly connected with ear plates 17. The four sliding rods 16 penetrate through the ear plates 17 and extend to the top of the ear plates 17. The sliding rods 16 are movably connected to the ear plates 17.

[0034] As a technical optimization solution of the present utility model, by providing the sliding rods 16 and the ear plates 17, the up and down movement of the support plate 2 can drive the ear plates 17 to move up and down on the surface of the sliding rods 16. At this time, the sliding rods 16 can limit the ear plates 17 and the support plate 2 in the front, back, left, and right directions, thereby improving the stability of the movement of the support plate 2.

[0035] Reference Figure 1 , a limiting ring 18 is fixedly connected to the top of the surface of the sliding rod 16. A timer 19 is fixedly installed at the rear side of the right side of the base 1. The timer 19 is electrically connected to the computer 3 through a wire.

[0036] As a technical optimization solution of the present utility model, by providing the limiting ring 18 and the timer 19, the limiting ring 18 can prevent the ear plates 17 from detaching from the surface of the sliding rods 16, and the timer 19 facilitates the user to control the cooling time after the model printing is completed.

[0037] Working principle and usage process of the present utility model: When in use, the servo motor 12 can be started through the computer 3. At this time, the output end of the servo motor 12 drives the driving gear 13 to rotate. Since the driving gear 13 meshes with the driven gear 101, the rotation of the driving gear 13 can drive the driven gear 101, the transmission rod 102 and the bidirectional lead screw 103 to rotate. The rotation of the bidirectional lead screw 103 can drive the two movable blocks 93 to move closer. Since the top of the second triangular plate 94 is in contact with the bottom of the first triangular plate 92, the movement of the second triangular plate 94 can drive the first triangular plate 92, the support plate 8 and the support plate 2 to move upward in sequence, thus facilitating the printing work. When printing, first convey the external wire to the inside of the 3D printer main body 6, and then the computer 3 can be used to start the 3D printer main body 6 for printing work. The computer 3 and the 3D printer main body 6 are prior arts. The structures and working principles of the computer 3 and the 3D printer in the comparative document application number: (CN202221324552.4) are the same, and will not be elaborated here. After printing, the user can start the servo motor 12 through manipulation to drive the driving gear 13, the driven gear 101, the transmission rod 102 and the bidirectional lead screw 103 to rotate in the reverse direction, so as to drive the movable block 93, the second triangular plate 94, the first triangular plate 92, the support plate 8 and the support plate 2 to move downward to return to the original position, thus facilitating the user to take the model. At the same time, after printing, by starting the timer 19, the cooling time of the model can be controlled. After cooling, the user can take out the model, so as to avoid the model colliding and rubbing with the 3D printer main body 6 when taking it.

[0038] To sum up: For this printer with a protective structure, by setting the connecting groove and the support plate 8, the support plate 8 can move up and down inside the connecting groove, so as to drive the support plate 2 and the model on its top to move up and down, thus facilitating the user to take the model and avoiding the model colliding with the 3D printer main body 6 when taking it, solving the problem that since the distance between the printed model and the printing nozzle is relatively close after the 3D printing work is completed, when taking the model, it is easy to cause the model to collide with the printing nozzle, and since the overall strength and toughness of the model are relatively low when it is just printed, it is easy to be damaged and there is a lack of a protective structure.
