Two fixing grooves 6 are opened on one side of the fixing block 2 close to the second circuit board 4, and an installation cavity 9 is opened in the fixing block 2. Two splicing blocks 5 are fixedly installed on one side of the second circuit board 4 close to the first circuit board 1. Both of the two splicing blocks 5 are adapted to the fixing grooves 6, and through holes are opened at the top and bottom of both of the two splicing blocks 5. A vertical rod 13 is movably installed in any one of the through holes. A clamping block 16 and a connecting plate 15 are respectively fixedly installed at both ends of any one of the vertical rods 13. A return spring 12 is sleeved on any one of the vertical rods 13. One end of any one of the return springs 12 is fixed on the corresponding vertical rod 13, and the other end of any one of the return springs 12 is fixed on the inner wall of the corresponding through hole. A rotating shaft 17 is rotatably installed in both of the two splicing blocks 5. A worm gear 22 and an elliptical wheel 11 are fixedly sleeved on both of the two rotating shafts 17. A worm 14 is rotatably installed in both of the two splicing blocks 5. The two worms 14 are respectively engaged with the corresponding worm gears 22. The tops of the two worms 14 are fixedly sleeved with turning knobs 7. Slots are opened at the top and bottom of both of the two fixing grooves 6. The clamping blocks 16 are adapted to the slots and are both arranged in a square structure. Through the above structural settings, when it is necessary to splice and fix between the first circuit board 1 and the second circuit board 4, first insert the two splicing blocks 5 into the corresponding fixing grooves 6 respectively, and then drive the rotation of the two worms 14 by rotating the two turning knobs 7. The two worms 14 drive the rotation of the two worm gears 22, which can drive the rotation of the two rotating shafts 17, which can drive the rotation of the two elliptical wheels 11. During the rotation of the elliptical wheels 11, they respectively squeeze the corresponding two connecting plates 15, which can drive the corresponding clamping blocks 16 to move up and down separately, so that the clamping blocks 16 are respectively clamped into the slots on the corresponding fixing grooves 6, and the two splicing blocks 5 and the fixing block 2 can be preliminarily spliced and fixed.
[0031] Combined with Figures 1-4As shown, movable holes are formed on both sides of the installation cavity 9. Cross bars 19 are movably installed in the two movable holes. Roller 10 and limit block 8 are fixedly installed at both ends of the two cross bars 19 respectively. Compression springs 20 are sleeved on the two cross bars 19. One end of each of the two compression springs 20 is fixed on the corresponding cross bar 19, and the other end of each of the two compression springs 20 is fixed on the inner wall of the corresponding movable hole. A locking bolt 18 is threadedly installed at the top of the fixed block 2. The bottom end of the locking bolt 18 is rotatably installed with a trapezoidal block 21 located between the two rollers 10. The top end of the locking bolt 18 is fixedly sleeved with a knob 3. Limit grooves are formed on one side of the two splicing blocks 5 close to each other. The limit block 8 is adapted to the limit groove and is set in a square structure. A slide rail is fixedly installed in the installation cavity 9. A slider fixedly connected to the trapezoidal block 21 is slidably installed on the slide rail. Through the above structural settings, by downwardly locking and rotating the knob 3, the locking bolt 18 is driven to rotate downward. The locking bolt 18 pushes the trapezoidal block 21 to move downward. During the movement of the trapezoidal block 21, the rollers 10 on both sides are squeezed, so that the two cross bars 19 can be driven to move left and right apart, and the two limit blocks 8 can be driven to move left and right apart, so that the two limit blocks 8 are respectively inserted into the limit grooves on the corresponding splicing blocks 5, and the two splicing blocks 5 can be finally fixedly spliced with the fixed block 2, and the first circuit board 1 and the second circuit board 4 can be finally spliced and fixed.

During the rotation of the elliptical wheels 11, they respectively squeeze the corresponding two connecting plates 15, which can drive the corresponding clamping blocks 16 to move up and down separately, so that the clamping blocks 16 are respectively clamped into the clamping grooves on the corresponding fixing grooves 6, and the two splicing blocks 5 can be preliminarily spliced and fixed with the fixing block 2. Then, by rotating the locking knob 3 downward, it drives the downward rotation of the locking bolt 18. The locking bolt 18 pushes the trapezoidal block 21 to move downward. During the movement of the trapezoidal block 21, it squeezes the rollers 10 on both sides, which can drive the left and right separation movement of the two cross bars 19, and then drive the left and right separation movement of the two limiting blocks 8, so that the two limiting blocks 8 are respectively clamped into the limiting grooves on the corresponding splicing blocks 5, and the two splicing blocks 5 can be finally fixed and spliced with the fixing block 2, and the first circuit board 1 and the second circuit board 4 can be finally spliced and fixed.
