A second FPC circuit board 5 is provided on the right side between the bottom plate 1 and the upper cover 3. A fixing rod 6 is fixedly connected to the top of the bottom plate 1. A chute 7 is opened on the inner side surface of the fixing rod 6. A sleeve rod 8 is inserted into the inner cavity of the chute 7. The sleeve rod 8 can slide up and down in the chute 7 and can rotate in the chute 7. A pressing rod 9 is fixedly connected to the side surface of the sleeve rod 8. A clamping block 18 is fixedly connected to the bottom of the upper cover 3. A clamping groove 17 is opened at the top of the fixing rod 6. The clamping block 18 can be inserted into the clamping groove 17.
[0020] A limiting rod 11 is fixedly inserted into the inner cavity of the chute 7. A through hole 12 is opened at the top of the sleeve rod 8. The sleeve rod 8 is sleeved on the limiting rod 11 through the through hole 12. The setting of the limiting rod 11 can make the sleeve rod 8 more stable when rotating.
[0021] A spring 13 is sleeved on the circumferential surface of the limiting rod 11. The spring 13 can play a downward rebounding effect on the sleeve rod 8, so as to achieve a more stable effect of limiting the FPC circuit board.
[0022] The number of the pressing rods 9 is four. The four pressing rods 9 are respectively located at the four corners of the top of the bottom plate 1. And protective pads 10 are provided at the bottoms of the four pressing rods 9. The four pressing rods 9 can respectively limit and extrude the first FPC circuit board 4 and the second FPC circuit board 5.
[0023] A sliding rod 14 is fixedly connected to the side surface of the sleeve rod 8. The other end of the sliding rod 14 is fixedly connected to a sliding block 15. A sliding track 16 is further opened in the inner cavity of the fixing rod 6. The sliding block 15 is slidably inserted into the sliding track 16. The setting of the sliding rod 14 and the sliding block 15 can make the sleeve rod 8 more stable when sliding. And the sliding track 16 is an annular strip-shaped groove, so that the sliding block 15 can slide up and down and horizontally in the sliding track 16 in the reverse direction.
[0024] The number of the clamping blocks 18 is four. The four clamping blocks 18 are respectively located at the four corners of the bottom of the upper cover 3. And the four clamping blocks 18 are respectively arranged corresponding to the clamping grooves 17 at the tops of the four fixing rods 6. The four clamping blocks 18 can make the upper cover 3 more stable, thereby improving the stability of the upper cover 3.
[0025] Working principle: First, pull the upper cover 3 upward. The upper cover 3 will drive the clamping block 18 to slide out of the clamping groove 17. Then, the first FPC circuit board 4 and the second FPC circuit board 5 can be inserted and connected to the places on the bottom plate 1 that need to be welded. Then, pull the pressure lever 9 upward and rotate the pressure lever 9 at the same time. When pulling the pressure lever 9 upward, it will slide upward along the limiting rod 11 and squeeze the spring 13. When rotating the pressure lever 9, it will drive the slider 15 to slide in the slideway 16 through the slide rod 14, so that the pressure lever 9 is more stable when rotating, making the four pressure levers 9 in two groups respectively located on the tops of the first FPC circuit board 4 and the second FPC circuit board 5. Then, release the pressure lever 9 that is pulled. The spring 13 will rebound downward to sleeve the rod 8, and the sleeve rod 8 will drive the pressure lever 9 to slide downward. The pressure lever 9 will respectively squeeze the first FPC circuit board 4 and the second FPC circuit board 5. The protection pad 10 can protect the first FPC circuit board 4 and the second FPC circuit board 5. Then, the first FPC circuit board 4 and the second FPC circuit board 5 can be welded. After the welding and installation are completed, the clamping block 18 at the bottom of the upper cover 3 can be aligned with the clamping groove 17, and pressing the upper cover 3 downward can insert the clamping block 18 into the clamping groove 17 to complete the installation of the upper cover 3.
