By setting up the triangular groove plate 28, the triangular groove on the triangular groove plate 28 can push the L-shaped connecting turn 6 to move up and down when moving horizontally, thereby driving the patch head 7 to move up and down.

[0030] Example 2

[0031] like Figure 1-5 As shown, on the basis of embodiment 1, the utility model provides a technical solution: preferably, the top of the track bar 4 is slidably connected with a storage groove 30, and an elastic block 31 is fixedly installed on the inner wall of the storage groove 30, and the number of the elastic blocks 31 is two, and the inner wall of the fuselage 1 is fixedly connected with a connecting plate 25, and a long slot 26 is provided on the side wall of the connecting plate 25, and a connecting block 27 is slidably connected to the inner wall of the long slot 26. By providing the long slot 26, the movement of the cylinder 24 can be limited.

[0032] A cylinder 24 is fixedly connected to the side wall of the connecting plate 25, and the cylinder 24 contacts the gear 21. A long slot 26 is provided on the side wall of the connecting plate 25, and a connecting block 27 is slidably connected to the inner wall of the long slot 26.

[0037] like Figure 1-5As shown, when in use, the motherboard that needs to be patched is lowered from the top of the storage slot 30. When the motherboard is lowered, the motherboard pushes the slope of the triangular part of the elastic block 31 downward, and the elastic block 31 is deformed and bent downward. When the motherboard contacts the inner bottom surface of the storage slot 30, the motherboard will be located below the elastic block 31, and the elastic block 31 will restore its original shape due to elasticity, thereby clamping the motherboard in the storage slot 30. When the motherboard is placed, the motor in the motor box 20 is started, and the motor drives the shaft to rotate. The rotation of the shaft drives the gear 21 to rotate. When the gear 21 rotates, the teeth are inserted between the cylinders 24, and the gear teeth are inserted into the cylinders 24. The gears will push the motor box 20, the connecting column 22, the rectangular block 23, the connecting block 27 and the triangular groove plate 28 to move. At the same time, the gear 21 will also drive the storage slot 30 to move when it rotates. The storage slot 30 will move along the track bar 4, and the triangular groove on the triangular groove plate 28 will drive the patch head 7 to do lifting movement through the sliding column 29. When the storage slot 30 moves to the bottom of the patch head 7, the patch head 7 will be closest to the mainboard and will start the patch work. When the patch work is completed, the motor running gear 21 will rotate and drive the triangular groove plate 28 and the storage slot 30 to move, and the staff can pry open the elastic block 31 to take out the mainboard.
