Four second pin holes 9 are provided on the top surface of the fixing bracket 2. A protective frame 3 is provided on the top surface of the fixing bracket 2. Four second pins 8 are provided on the bottom surface of the protective frame 3. Two mounting grooves 15 are provided on the bottom surface of the mounting bracket 1. Locking tongues 12 are provided inside each of the two mounting grooves 15. A return spring 14 is provided on one side of each of the two locking tongues 12. A bottom cover 11 is provided at the bottom of each of the two mounting grooves 15. The four first pin holes 7 are located at each corner of the mounting bracket 1, and the positions of the four first pins 6 correspond one-to-one with the first pin holes 7. The four first pins 6 are integrally formed with the fixing bracket 2. The first pins 6 are all installed in the first pin holes 7. The four second pin holes 9 are set at each corner of the top surface of the fixed frame 2, and the second pin holes 9 are aligned with the vertical center axis of the first pins 6. The four second pins 8 correspond one-to-one with the second pin holes 9, and the four second pins 8 are all installed in the second pin holes 9. The four second pins 8 are integrally formed with the guard frame 3. The four sliding grooves 5 are evenly set on the surface of both sides of the fixed frame 2. The positions of the four sliders 4 correspond one-to-one with the positions of the sliding grooves 5, and the sliders 4 are integrally formed with the fixed frame 2. The four sliders 4 are all installed in the sliding grooves 5. The four locking blocks 13 are evenly inserted into the bottom end of the sliding grooves 5. The two mounting grooves 15 are all set at the end near the sliders 4, and the two bottom covers 11 are all fixed to the bottom surface of the mounting frame 1 by two fixing bolts and cover the mounting grooves 15. One end of the two locking tongues 12 extends through the mounting frame 1, and the locking tongues 12 are T-shaped. The two return springs 14 are all installed in the mounting grooves 15 and abut against the locking tongues 12.

[0027] First, the mounting bracket 1 is installed at the location where the circuit board 10 needs to be installed, providing a mounting location for the circuit board 10. The mounting bracket 1 can be installed using fixing bolts. The first pin 6 at the top of the fixing bracket 2 is installed in the first pin hole 7 of the mounting bracket 1. The circuit board 10 is fixed to the mounting bracket 1 by the fixing bracket 2. The protective bracket 3 at the top of the fixing bracket 2 is engaged with the second pin hole 9 on the bottom surface of the fixing bracket 2 by the second pin 8. The protective bracket 3 will block external impacts and protect the circuit board 10 installed on the mounting bracket 1. Two sliding grooves 5 are evenly set at both ends of the fixing bracket 2 on the left and right sides. Since the four sliders 4 are all installed in the sliding grooves 5, when the fixing bracket 2 moves upward, the sliders 4 of the mounting bracket 1... The device will move within the slide groove 5 of the fixed frame 2. The cooperation between the slide groove 5 and the slider 4 will serve as a guide to prevent the fixed frame 2 from shifting when moving up and down. Four locking blocks 13 are evenly inserted into the bottom end of the slide groove 5 to lock the slider 4 and prevent the fixed frame 2 from moving excessively upward. The two bottom covers 11 on the bottom surface of the mounting frame 1 are covered by two fixing bolts on the mounting groove 15 to protect the locking tongue 12 and the return spring 14 inside the mounting frame 1. The locking tongue 12 passes through one end of the mounting frame 1 to lock the locking hole on the surface of the fixed frame 2 to fix the fixed frame 2. The return spring 14 inside the mounting groove 15 will push the locking tongue 12 out of the mounting groove 15 through its own elasticity to lock the locking hole of the fixed frame 2.

[0028] During installation, press the locking tongues 12 on both sides of the mounting bracket 1 to retract them into the mounting groove 15. When the locking tongues 12 are retracted, the fixing bracket 2 can move upward. Since the slider 4 of the mounting bracket 1 is installed in the slide groove 5 of the fixing bracket 2, the fixing bracket 2 will move in the direction that the slider 4 moves in the slide groove 5, causing the first pin 6 on the bottom surface of the fixing bracket 2 to disengage from the first pin hole 7 on the top surface of the mounting bracket 1. After disengagement, attach the circuit board 10 to the top surface of the mounting bracket 1, aligning the bolt holes of the circuit board 10 with the first pin hole 7 of the mounting bracket 1. After alignment, press the fixing bracket 2 to move it downward, allowing the first pin 6 on the bottom surface of the fixing bracket 2 to disengage from the first pin hole 7. After the pin 6 passes through the bolt hole of the circuit board 10, it is installed into the first pin hole 7 of the mounting bracket 1. The circuit board 10 is fixed to the mounting bracket 1 by the fixing bracket 2. When the mounting bracket 1 continues to move downward, the locking holes on both sides of the fixing bracket 2 will align with the locking tongue 12, and the locking tongue 12 will pass out of the locking hole. The fixing bracket 2 is fixed by the locking tongue 12. When it is necessary to remove the circuit board 10, press the locking tongue 12 again to make the locking tongue 12 retract into the mounting groove 15. When the locking tongue 12 is retracted, the fixing bracket 2 is moved upward, so that the first pin 6 on the bottom surface of the fixing bracket 2 is disengaged from the first pin hole 7. After disengagement, the circuit board 10 can be removed from the mounting bracket 1. Specific Implementation Example 2:

[0030] Reference Figures 1-7An ultra-thin circuit board, further based on the basic structure in specific embodiment one, according to the appendix Figure 5 and attached Figure 7 A heat sink can be installed on the bottom surface of the mounting bracket 1. The heat sink is fixed to the bottom surface of the mounting bracket 1 by four fixing bolts, so that the heat sink is attached to the circuit board 10 on the bottom surface of the mounting bracket 1, thereby increasing the heat dissipation of the circuit board 10.

[0031] In summary:

[0032] 1. During installation, press the locking tongues 12 on both sides of the mounting bracket 1 to retract them into the mounting groove 15. When the locking tongues 12 are retracted, the fixing bracket 2 can move upward. Since the slider 4 of the mounting bracket 1 is installed in the slide groove 5 of the fixing bracket 2, the fixing bracket 2 will move in the same direction as the slider 4 moves in the slide groove 5. This causes the first pin 6 on the bottom surface of the fixing bracket 2 to disengage from the first pin hole 7 on the top surface of the mounting bracket 1. After disengagement, attach the circuit board 10 to the top surface of the mounting bracket 1, aligning the bolt holes of the circuit board 10 with the first pin holes 7 of the mounting bracket 1. After alignment, press the fixing bracket 2 to move it downward, allowing the first pin 6 on the bottom surface of the fixing bracket 2 to pass through the bolt holes of the circuit board 10 and be installed into the mounting bracket. In the first pin hole 7 of the mounting bracket 1, the circuit board 10 is fixed to the mounting bracket 1 by the fixing bracket 2. When the mounting bracket 1 continues to move downward, the locking holes on both sides of the fixing bracket 2 will align with the locking tongue 12, and the locking tongue 12 will pass through the locking hole. The fixing bracket 2 is fixed by the locking tongue 12. When the circuit board 10 needs to be removed, the locking tongue 12 is pressed again to retract the locking tongue 12 into the mounting groove 15. When the locking tongue 12 is retracted, the fixing bracket 2 is moved upward, so that the first pin 6 on the bottom surface of the fixing bracket 2 is disengaged from the first pin hole 7. After disengagement, the circuit board 10 can be removed from the mounting bracket 1. The entire installation or removal does not require installation bolts, which solves the disadvantage of needing to frequently remove screws when installing or replacing the circuit board 10.
