[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figures 1-4 This utility model provides an adjustable 3D printing fixture, including a mounting plate 1 and a printing probe 4. The front of the mounting plate 1 is provided with an adjustment component, which includes an adjustment groove 102 opened at the center of the front of the mounting plate 1. A sliding seat 2 is slidably connected inside the adjustment groove 102. A protrusion is provided on the front of the sliding seat 2. A sliding groove for sliding the protrusion is opened on the front of the mounting plate 1. A threaded post 201 is fixedly connected to the front of the protrusion. A locking disc 202 is threadedly connected to the outside of the threaded post 201.

[0025] According to the size of the printing probe 4 to be clamped, the position of the sliding seat 2 in the adjusting groove 102, due to the design of the sliding groove, the protrusion and the threaded column 201 thereon can freely slide along the direction of the sliding groove, thereby realizing the lateral adjustment of the sliding seat 2. When the sliding seat 2 is adjusted to the appropriate position, the rotating locking disc 202 is moved downward along the external threads of the threaded column 201 until the locking disc 202 is in close contact with the front surface of the mounting plate 1. At this time, the friction force generated by the locking disc 202 firmly locks the sliding seat 2 in the current position in the adjusting groove 102, preventing it from moving during printing.

[0026] In this embodiment, the front surface of the adjusting assembly is fixedly connected with a connecting column 3, and the end of the connecting column 3 is provided with a fixing assembly 5. The fixing assembly 5 comprises a first fixing piece 501 connected with the connecting column 3, a second fixing piece 502 screwed on the front surface of the first fixing piece 501, a limiting cavity provided between the first fixing piece 501 and the second fixing piece 502, a probe 4 placed in the limiting cavity, a plurality of equidistant arc-shaped limiting elastic pieces 505 fixedly connected to the inner wall of the limiting cavity, the arc-shaped limiting elastic pieces 505 being annularly distributed on the opposite surfaces of the second fixing piece 502 and the first fixing piece 501, connecting portions 504 fixedly connected to the two sides of the second fixing piece 502 and the first fixing piece 501, and bolts connecting every two abutting connecting portions 504. The recessed part of the arc-shaped limiting elastic piece 505 is provided with a "C"-shaped weakening groove 5051, and the side of the limiting cavity facing the arc-shaped limiting elastic piece 505 is provided with an avoiding groove 503.

[0027] After the sliding seat 2 of the adjusting assembly is adjusted to the appropriate position and locked, the connecting column 3 is fixed to the front surface of the sliding seat 2. At this time, the fixing assembly 5 is connected with the connecting column 3 through the first fixing piece 501, forming the basic structure for clamping the printing probe 4. The rear end of the printing probe 4 is inserted into the limiting cavity formed by the first fixing piece 501 and the second fixing piece 502. The design of this limiting cavity is to tightly wrap the printing probe 4, ensuring that it is stably and accurately fixed on the clamp. The arc-shaped limiting elastic pieces 505 are annularly distributed on the opposite surfaces of the second fixing piece 502 and the first fixing piece 501. They will automatically adjust their bending degree according to the size of the printing probe 4 to provide appropriate clamping force.

[0028] This design ensures that the printing probe 4 can be uniformly and tightly clamped regardless of the size change. After the printing probe 4 is placed in the limiting cavity, the second fixing piece 502 is pulled closer to the first fixing piece 501 by rotating the bolts on the second fixing piece 502 (these bolts pass through the holes of the connecting portions 504). During this process, the arc-shaped limiting elastic pieces 505 will further bend until they are in close contact with the printing probe 4 and maintain the clamping state through their elastic force.

[0029] The "C"-shaped weakened groove 5051 formed in the recess of the arc-shaped limiting elastic sheet 505 helps the elastic sheet to bend more easily when subjected to pressure, thereby adapting to printing probes 4 of different sizes, and the avoidance groove 503 formed on the side of the limiting cavity facing the arc-shaped limiting elastic sheet 505 provides additional space for the bending of the elastic sheet, preventing the elastic sheet from interfering with the inner wall of the limiting cavity during the bending process. Through the design of the arc-shaped limiting elastic sheet 505 and the weakened groove 5051, the fixing assembly 5 can tightly and uniformly clamp printing probes 4 of different sizes, improving the versatility and adaptability of the clamp. The elastic force of the arc-shaped limiting elastic sheet 505 and the fastening effect of the bolt together ensure the stability of the printing probe 4 during printing, reducing the possibility of shaking and displacement. The design of the weakened groove 5051 and the avoidance groove 503 reduces the pressure on the surface of the printing probe 4 during the bending process of the arc-shaped limiting elastic sheet 505, thereby reducing the risk of damage to the printing probe 4.

[0030] In the embodiment, the mounting plate 1 is fixedly connected with mounting portions 101 at four corners, and each mounting portion 101 is internally provided with an elongated mounting hole 1011. First, the mounting plate 1 is placed on a predetermined mounting position, and the mounting portion 101 is aligned with the corresponding mounting point on the 3D printer or other fixed structure. Since the mounting hole 1011 is elongated, the user can select a suitable mounting position within the length range of the mounting hole 1011 according to actual needs. This design provides additional flexibility, so that the clamp can adapt to different installation environments and needs. Once the mounting position is determined, a suitable fastener can be used to pass through the mounting hole 1011 and be fixed on the 3D printer or other fixed structure.

[0031] The working principle and use process of the utility model are as follows: first, the mounting plate 1 is placed on a predetermined mounting position, and the mounting portion 101 is aligned with the corresponding mounting point on the 3D printer or other fixed structure. Since the mounting hole 1011 is elongated, the user can select a suitable mounting position within the length range of the mounting hole 1011 according to actual needs. This design provides additional flexibility, so that the clamp can adapt to different installation environments and needs. Once the mounting position is determined, a suitable fastener can be used to pass through the mounting hole 1011 and be fixed on the 3D printer or other fixed structure. According to the size of the printing probe 4 to be clamped, the position of the sliding seat 2 in the adjusting groove 102 is adjusted. Due to the design of the sliding groove, the protrusion and the threaded column 201 thereon can freely slide along the direction of the sliding groove, thereby realizing the transverse adjustment of the sliding seat 2.

[0032] When the sliding seat 2 is adjusted to the appropriate position, the rotating locking disc 202 is moved downward along the external thread of the threaded column 201 until the locking disc 202 is in close contact with the front surface of the mounting plate 1, at this time, the friction generated by the locking disc 202 firmly locks the sliding seat 2 in the current position in the adjusting groove 102, preventing it from moving during printing, after the sliding seat 2 of the adjusting assembly is adjusted to the appropriate position and locked, the connecting column 3 is fixed to the front surface of the sliding seat 2;

[0033] At this time, the fixing assembly 5 is connected to the connecting column 3 through its first fixing piece 501, forming the basic structure for clamping the printing probe 4, the rear end of the printing probe 4 is inserted into the limiting cavity formed by the first fixing piece 501 and the second fixing piece 502, this limiting cavity is designed to tightly wrap the printing probe 4, ensuring that it is stably and accurately fixed on the clamp, the arc-shaped limiting spring pieces 505 are annularly distributed on the opposite surfaces of the second fixing piece 502 and the first fixing piece 501, they will automatically adjust their bending degree according to the size of the printing probe 4 to provide appropriate clamping force, this design ensures that no matter how the size of the printing probe 4 changes, uniform and tight clamping can be achieved, after the printing probe 4 is placed in the limiting cavity, the second fixing piece 502 is pulled closer to the first fixing piece 501 by rotating the bolts on the second fixing piece 502 (these bolts pass through the holes of the connecting part 504), during this process, the arc-shaped limiting spring pieces 505 will further bend until they are in close contact with the printing probe 4 and maintain the clamping state through their elastic force.
