[0026] A spring 10 is movably mounted on the surface of the cross bar 4 , and a limiting plate 11 is fixedly mounted on the other side of the cross bar 4 .

[0027] Reference Figure 4 Through the structural design of the spring 10 and the limit plate 11, and through the mutual cooperation between the structures, the automatic locking function is realized, thereby simplifying the circuit board fixing structure by utilizing the deformable characteristics, thereby reducing the user's adjustment time.

[0028] A mounting plate 12 is fixedly mounted on one side of the positioning seat 2 , and a circuit board A13 is fixedly mounted on the bottom of one side of the mounting plate 12 .

[0029] Reference Figure 1 and Figure 2 By setting the assembly plate 12, it is convenient to support the positioning seat 2 and the circuit board A13 while limiting their positions, and at the same time, the stability and reliability between the positioning seat 2 and the circuit board A13 can be increased.

[0030] A slot 14 is formed at the top of the assembly plate 12 , and positioning rods 15 are formed at two corners of the top of the circuit board A13 .

[0031] Reference Figure 2 By setting the card slot 14, it is convenient to limit the connection block 16, thereby reducing the shaking when the circuit board A13 and the circuit board B18 are placed overlapping.

[0032] Connecting blocks 16 are fixedly mounted on both sides of the surface of the shaft sleeve 7 , and the positions of the connecting blocks 16 are matched with the slots 14 .

[0033] Reference Figure 3 By setting the connecting block 16, it is convenient to cooperate with the card slot 14 to increase the stability of the circuit board A13 and the circuit board B18 when they overlap, avoiding the mutual misalignment caused by the interference of the external environment when the circuit board A13 and the circuit board B18 overlap, thereby extending the service life of the double-layer circuit board.

[0034] A vertical plate 17 is fixedly mounted on one side of the connection block 16 , and a circuit board B18 is fixedly mounted on one side of the vertical plate 17 .

[0035] Reference Figure 3 By setting the vertical plate 17, it is convenient to cooperate with the assembly plate 12 to further increase the stability of the circuit board A13 and the circuit board B18.

[0036] Vertical holes 19 are formed on both sides of the top of the circuit board B18.

[0037] Reference Figure 3 By setting the vertical hole 19, it is convenient to cooperate with the positioning rod 15 to ensure that the circuit board A13 and the circuit board B18 are placed vertically, and it can also ensure that the gap between the circuit board A13 and the circuit board B18 is within a safe range when they overlap, thereby reducing the mutual interference between the circuit board A13 and the circuit board B18.

[0038] Working principle: When adjusting the tilt angle of circuit board A13 and circuit board B18, the limit plate 11 drives the cross bar 4 to move outward, and the baffle 5 is driven to move synchronously through the cross bar 4. The baffle 5 compresses the spring 10, and the spring 10 is deformed after receiving the pressure. At this time, the positioning pin 6 is disengaged from the inside of the positioning hole 9, and the circuit board B18 is rotated. The positioning shaft 1 cooperates with the shaft sleeve 7 to ensure that the circuit board B18 rotates with the positioning shaft 1 as the center of the circle. When the angle between the circuit board B18 and the circuit board A13 is appropriate, the limit plate 11 is released. At this time, the spring 10 releases the tension and pushes the positioning pin 6 to move inward through the baffle 5. The positioning pin 6 enters the corresponding positioning hole 9 to complete the locking. When the circuit board B18 and the circuit board A13 are required to be locked, the limit plate 11 is released. When A13 is overlapped, the limit plate 11 drives the cross bar 4 to move outward, and the cross bar 4 drives the baffle 5 to move synchronously, and the baffle 5 compresses the spring 10. The spring 10 is deformed after receiving the pressure. At this time, the positioning pin 6 is disengaged from the positioning hole 9, and the circuit board B18 is rotated. The positioning shaft 1 cooperates with the sleeve 7 to ensure that the circuit board B18 rotates with the positioning shaft 1 as the center, until the small diameter end of the positioning rod 15 is inserted into the vertical hole 19, and the large diameter end of the positioning rod 15 is used to support the circuit board B18. At this time, the connecting block 16 is limited by the slot 14, and the limit plate 11 is released. The spring 10 releases the tension of the baffle 5 to push the positioning pin 6 to move inward, and the positioning pin 6 enters the corresponding positioning hole 9 to complete the locking.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
