Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Figure 1: the multi-angle hand electric drill includes an electric drill body 1, a transmission shaft 3, a drill bit 10 and an angle adjustment device, the electric drill body 1 is connected to the drill card 2, and the drill card 2 is connected to the angle adjustment device through the transmission shaft 3 The tail end of the angle adjustment device is connected to each other, and the head end of the angle adjustment device is connected to the drill bit 10 through the drill bit clamp 9. The handle of the electric drill body 1 is provided with a switch 15 .

Described angle adjustment device has angle adjustment box 12, is provided with in angle adjustment box 12: the 1st bevel gear 6, the 2nd bevel gear 7, axle sleeve 13, bevel gear axle sleeve 14, bevel gear drive shaft 8, driven Gear 5 and driving gear 4, the driving gear 4 is connected with the transmission shaft 3 through the shaft sleeve 13 fixed on the angle adjustment box, the driving gear 4 is meshed with the driven gear 5, and the front end of the driven gear 5 is connected to the first gear through the shaft. The bevel gears 6 are connected, the tail end of the driven gear 5 is inserted into the shaft sleeve 13 fixed on the angle adjustment box, the front end of the first bevel gear 6 is inserted into the bevel gear sleeve 14, the first bevel gear 6 and the second bevel gear The gears 7 are meshed, the tail end of the second bevel gear 7 is connected to the shaft sleeve 13 through the bevel gear transmission shaft 8, the front end of the second bevel gear 7 is inserted into the bevel gear sleeve 14, and the bevel gear sleeve 14 is inserted into the drill card 9 .

An auxiliary handle 11 is installed on the angle adjustment box 12 .

The working process of the present utility model is as follows:

As shown in Figure 2, when the switch 15 is pressed, the transmission shaft 3 drives the driving gear 4 to rotate clockwise, and drives the driven gear 5 to rotate counterclockwise. The driven gear 5 is integrated with the first bevel gear 6, and the first bevel gear 6 is also Rotate counterclockwise, the first bevel gear 6 drives the second bevel gear 7 to rotate clockwise, the bevel gear transmission shaft 8 rotates clockwise, the drill card 9 and the drill bit 10 also rotate clockwise under the drive of the bevel gear transmission shaft 8 , the drill bit 10 rotates clockwise to complete the drilling work.
