[0038] Example 3

[0039] Working principle: When the operator drills a hole in metal, he first fixes the drill bit 5 on the rotating shaft 45 through the clamping jaws 454, then slides the protection rod 46 in the clamping ring 415, sets it to the maximum feed depth of the drill bit 5, and then starts the motor 2. The motor 2 drives the output shaft 3 to rotate, and the output shaft 3 drives the rotating shaft 45 to rotate through the cross shaft 451. After the rotating shaft 45 rotates, it drives the No. 1 gear 44 to rotate. The rotation of the No. 1 gear 44 drives the No. 2 gear 453 to rotate. The rotation of the No. 2 gear 453 drives the rotation of the worm 43. The rotation of the worm 43 drives the rotation of the turbine 42. The large transmission ratio of the worm 43 and the turbine 42 reduces the speed transmitted by the rotating shaft 45. Due to the unidirectional transmission of the turbine 42 and the worm 43, the up and down movement of the housing 41 can only be The rotation of the worm 43 drives the meshing ring 61 on one side of the turbine 42 to rotate. After the meshing ring 61 rotates, it drives the clutch sleeve 62 engaged therewith to rotate. The clutch sleeve 62 drives the spline 63 to rotate through the limit block 624. After the spline 63 rotates, it drives the reset gear 631 to rotate on the rack 65, thereby driving the housing 41 to move downward in the slide groove 13 through the slide rail 411. The sliding of the pulley 47 at one end of the turbine 42 in the limit plate 48 makes the downward movement of the housing 41 more stable. After the housing 41 moves downward, the limit ring 414 on one side of the housing 41 drives the bearing 452 to move downward. At the same time, the bearing 452 drives the rotating shaft 45 to move downward. After the rotating shaft 45 moves downward, the cross shaft 451 slides downward inside the output shaft 3.

[0040] During the drilling process of the drill bit 5, the rotation speed of the drill bit 5 is proportional to the feed speed of the drill bit 5, which makes the drill bit 5 less likely to be damaged and always maintains a reasonable feed speed;

[0041] When the drill bit 5 reaches the set feeding depth, the switch at the bottom of the protection rod 46 is squeezed by the metal surface and then contracts. At this time, the motor 2 reverses and drives the housing 41 to rise to the initial position.

[0042] When manual feeding is required, the operator pushes the clutch sleeve 62 to engage with the meshing tooth 611 fixed on the rocker 64, thereby connecting the clutch sleeve 62 to the rocker 64. At this time, the rotation of the turbine 42 will not drive the reset gear 631 to rotate through the clutch sleeve 62. After the operator manually shakes the rocker 64, the meshing ring 61 on one side of the rocker 64 cooperates with the extension tooth 622 to drive the clutch sleeve 62 to rotate, and then the clutch sleeve 62 drives the reset gear 631 on the spline 63 to rotate, thereby manually controlling the feeding of the drill bit 5.
