When people need to drill, people firstly hold the handle 1 to place the wood drilling tool on the wood to be drilled, the protection device 15 is in contact with the wood, the drill bit 14 is arranged right above the drilling position, then people pull the cross rod 11 upwards, the cross rod 11 drives the motor 9, the rotating shaft 12, the clamp 13, the drill bit 14 and the pull rod 10 to move upwards, the motor 9 drives the mounting seat 8 and the sliding block 5 to move upwards, the first spring 6 is stretched, then people start the motor 9 to work, the rotating shaft 12, the clamp 13 and the drill bit 14 are driven to rotate by the rotation of the output shaft of the motor 9, then people remove hands from the cross rod 11, the sliding block 5, the motor 9 and the drill bit 14 can move downwards under the spring force of the first spring 6, the drill bit 14 is in contact with the wood to drill, when the sliding block 5 returns to the original position, the drill bit 14 is in place, then people pull the cross rod 11 upwards, further, the drill bit 14 is pulled out of the hole, then people can move the drilling device to a position needing drilling at the lower part for drilling, the air inlet net 3 can ventilate the first shell 2, the heat dissipation of the motor 9 is facilitated, the device is protected to be intact, meanwhile, wood chips can be prevented from entering the first shell 2, the safety of the motor 9 is further protected, the baffle plate 7 can provide support for the first spring 6, when the drill bit 14 is long in service time and seriously worn and needs to be replaced, people separate the protection device 15 from the first shell 2, then people can loosen the clamp 13 to replace the drill bit 14, after people replace the drill bit 14, people clamp the clamp 13 again, then combine the protection device 15 with the first shell 2, so that the protection of the drill bit 14 can be realized, and the damage of foreign objects to the drill bit 14 is avoided, meanwhile, when the drill bit 14 is broken in the drilling process, people are protected, the situation of hurting people is prevented, and the safety is higher.
When people need to replace the drill bit 14, people press the pull ring 156 inwards, the pull ring 156 drives the connecting rod 155 to move inwards, the second spring 157 is compressed, the elastic rod 151 deforms, and then the hook 152 is driven to be disengaged from the groove 153, then people can take the second housing 150 down, after people take the second housing 150 down, people remove hands from the pull ring 156, stop pressing the pull ring 156, and then the pull ring 156 and the connecting rod 155 can recover to the original position under the elastic force action of the second spring 157 and the elastic rod 151, then people replace the drill bit 14, after people replace the drill bit 14, people press the pull ring 156 inwards again, and then the hook 152 moves inwards, people can install the second housing 150, then people remove hands from the pull ring 156, and then the hook 152 is combined with the groove 153, so that the first housing 2 is connected with the second housing 150, therefore, the drill bit 14 can be protected in the second housing 150, the probability of damage to the drill bit 14 caused by foreign objects is reduced, the drill bit 14 can be effectively protected to be intact, the rubber pad 158 can enable the first housing 2 and the second housing 150 to be combined more tightly, the anti-slip pad 1510 can prevent the stability of the air conditioner in the working process, the sliding condition cannot occur, the air outlet net 1511 can keep the flow of air in the first housing 2 and the second housing 150, and meanwhile, wood chips can be prevented from entering the second housing 150 to affect equipment.
When people need to drill, people firstly pull the cross rod 11 upwards to further enable the motor 9 to move upwards, the first spring 6 is stretched, the motor 9 drives the cylinder body 16 to move upwards, the check valve 164 is pressed to be opened, air at the lower part in the cylinder body 16 is discharged through the large air inlet hole 163 and the small air inlet hole 165, the exhaust speed is high, people pull the cross rod 11 easily, the work efficiency of people is improved, the work time is shortened, when the bottom of the cylinder body 16 is not in contact with the stop block 167 any more, the stop block 167 can rotate clockwise under the action of the elastic force of the elastic sheet 1612, the stop block 167 blocks the cylinder body 16, the downward movement of the motor 9 is further prevented, the situation that people always pull the cross rod 11 by hands is avoided, the burden of people is relieved, the limit block 1611 can prevent the stop block 167 from rotating too far, the people are not beneficial to withdraw the stop block 167, when people move the drill bit, when the block 167 is separated from the bottom of the cylinder 16, the motor 9 and the drill bit 14 move downwards under the action of the spring force of the first spring 6, the check valve 164 is pressed to be closed, the large air inlet hole 163 is closed, the cylinder 16 can only intake air through the small air inlet hole 165, the air intake speed is slow, and the descending speed of the motor 9 is slow, so that the instant force generated when the drill bit 14 is in contact with wood is reduced, the safety of the drill bit 14 is protected, the drill bit 14 is not easy to break, the drill bit 14 drills, after the drill bit 14 drills a hole, people pull the cross rod 11 upwards again, the cylinder 16, the motor 9 and the drill bit 14 move upwards, the drill bit 14 is pulled out of the drilled hole, and after the cylinder 16 is separated from the block 167, the cylinder 16 is blocked by the block 167, and is ready for the next drilling.
Before people drill, people can adjust the descending distance of the drill bit 14 by rotating the nut 171 to further control the drilling depth, when people need to drill deeper holes, people rotate the rotating rod 172 anticlockwise to drive the nut 171 to rotate anticlockwise on the threaded pipe 17, the cushion block 173 moves upwards along with the nut, further the distance between the cushion block 173 and the first shell 2 is increased, further the descending distance of the drill bit 14 is increased, the holes drilled by the drill bit 14 are deeper, when people need to drill shallower holes, people rotate the rotating rod 172 clockwise to drive the nut 171 to rotate clockwise on the threaded pipe 17, the cushion block 173 moves downwards along with the cushion block 173, further the distance between the cushion block 173 and the first shell 2 is reduced, further the descending distance of the drill bit 14 is reduced, the holes drilled by the drill bit 14 are shallower, further the drilling depth can be accurately controlled, and the adjustment can be carried out according to actual needs of people, the drilling machine has the advantages that the operation of people is facilitated, the situation of repeatedly drilling can be avoided, the time of people is saved, and the drilling efficiency is improved.
When people start the motor 9, the rotation of the output shaft of the motor 9 drives the rotating shaft 12 to rotate, and further drives the fan blade 183 to rotate, and then wind is generated, and after the wind is guided by the wind deflector 185, the wood dust drilled during drilling the drill bit 14 is blown to one direction, and then the wood dust is blown off from the wood, when an obstacle is on the right side of the wood, people can rotate the second housing 150, and further drive the bent rod 184 and the wind deflector 185 to rotate, and then the direction of the wind guided out by the wind deflector 185 is changed, so that the raised dust generated during blowing the wood dust is reduced, the long-time work of people is facilitated, the influence of the raised dust during the work of people can be reduced, the health of people is facilitated, the fan blade 183 can be protected by the protection ring 182, meanwhile, the influence on the first housing 2 and the second housing 150 can be reduced when the fan blade 183 is damaged, the loss is reduced, and when people close the motor 9, the, and then the wood dust blowing operation is stopped.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
