[0058] First, place the bottom plate 21 on the workbench 15, and after adjusting the reference and size, lock the fixing groove of the bottom plate 21 with the slot 151 of the workbench 15 by bolts. Place one end of the main chord into the base device 3, and make the horizontal top surface and the vertical rear side of the main chord respectively contact the first positioning block 34 and the second positioning block 35, and make the right end of the main chord contact the limit plate 33. At this time, the boring positions of the horizontal and vertical surfaces of the main chord correspond to the openings 331 of the horizontal and vertical surfaces of the upper base 31 respectively; screw the screw 43 of the tightening device 4, and the screw 43 drives the push block 44 and the top block 45 to move toward the main chord, so that the two waists of the top block 45 respectively support the horizontal bottom surface and the vertical front side surface of the main chord, and then screw the bolt into the locking hole 37, cooperate with the tightening device 4, and fix the main chord firmly in the upper base 31. Place the base device 3 with the main chord installed on the bottom plate 21, place the right end of the base device 3 against the positioning plate 23, and then adjust the base device 3 in the left and right directions so that the boring position on the horizontal plane of the main chord is aligned with the drill bit 13 of the boring device 1, screw the bolt into the fixing hole 221 on the fixing plate 22, and fix the base device 3 on the horizontal plane; screw the handle 55 of the clamping device 5 to drive the stud 53 to move in the connecting tube 52, and the stud 53 drives the pressure head 54 to descend, so that the pressure head 54 presses on the base device 3, and fixes the base device 3 on the vertical plane. At this time, the support roller 62 of the support device 6 supports the other side of the main chord.

[0059] The drilling and boring device 1 is started, and the motor 14 drives the drill bit 13 to rotate through the transmission box 12, and then moves downward on the front side of the fixed column 11 through the transmission box 12, driving the drill bit 13 to move downward, and the drill bit 13 enters the base device 3 through the opening 331 on the horizontal plane of the upper base 31, and can drill the boring position on the horizontal plane of the main chord. After the boring of this surface is completed, the transmission box drives the drill bit 13 to move upward, so that the drill bit 13 leaves the base device 3.

[0060] After boring the horizontal surface of the main chord, turn the handle 55 of the clamping device 5 to drive the stud 53 to move in the connecting tube 52. The stud 53 drives the pressure head 54 to rise, so that the pressure head 54 no longer presses the base device 3, and then loosen the bolts on the fixing plate 22 so that it no longer fixes the base device 3. Flip the base device 3 to the left by 90°, so that the vertical surface of the upper base 31 faces upward and becomes a horizontal surface. The base device 3 drives the main chord to flip, so that the vertical surface of the main chord flips upward and becomes a horizontal surface. Then screw the bolts into the fixing holes 221 of the fixing plate 22, and press the pressure head 54 of the clamping device 5 on the base device 3 to fix the base device 3 again.

[0061] The boring device 1 is started to allow the drill bit 13 to enter the base device 3 through the opening 331 on the horizontal plane of the upper base 31, so that the boring position on the horizontal plane of the main chord can be bored, thereby boring both sides of the main chord.

[0062] After one end of the main chord is bored and drilled, loosen the bolts of the fixing plate 22, the pressure head 54 of the clamping device 5, the bolts of the locking hole, and the top block 45 of the clamping device 4, remove the main chord, and install and drill the other end of the main chord in the above manner to complete the boring and drilling work at both ends of the main chord.

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
