Fig. 1-5 is please referred to, the present invention provides a kind of technical solution: a kind of electric drill of the protecting against shock that band is self-locking protection, including
Electric drill ontology 1, the output end of the electric drill ontology 1 are connected with output shaft 2, and the outside of the electric drill ontology 1 is fixed with the first bullet
Spring column 4, first spring stack 4 are connected to the side of cylinder 5, and the inside of the cylinder 5 is articulated with the one of second spring column 6
Side, the other side of the second spring column 6 are articulated with the outer ring of first bearing 7, and the inner ring of the first bearing 7 is fixed with triangle
The body of rod 8, one end of the triangle body of rod 8 are welded in the lumen centers position of outer cover 9, and the outside of the outer cover 9 is welded with screw thread
Cylinder 10, the side of the threaded cylindrical 10 offer slot 14, and the avris of the slot 14 offers through slot 11, the through slot
Side is articulated with the side of set square 12 in 11, and the other side of the set square 12 is hinged with fixture block 13, and the one of the output shaft 2
Side offers the delthyrium 3 to match with the triangle body of rod 8, and the outside of the triangle body of rod 8 offers conduit 23, the outer cover 9
Outside through there is side to be located at the l-shaped rod body 24 in conduit 23, the other side of the l-shaped rod body 24 is fixed with briquetting 27,
The side of the briquetting 27 is connected to the outside of outer cover 9 by third spring 26, offers in the delthyrium 3 and hooks body 25
The hanging hole 28 to match.
Specifically, the inner ring of second bearing 15 is fixed in the outside of the cylinder 5, the outer ring of the second bearing 15 passes through
First spring 16 is connected to the inside of outer cover 9；First spring 16 can be improved the shock resistance effect of cylinder 5.First spring
16 quantity is no less than three, and the first spring 16 is evenly distributed on the inside of outer cover 9；So that the shock resistance effect of outer cover 9 is more
It is good.First spring stack 4 and second spring column 6 include cylinder body 17, piston 18 and piston rod 20, and 18 activity of piston is even
It is connected to the inner cavity of cylinder body 17, the piston rod 20 is fixedly connected on the side of piston 18；So that the first spring stack 4 and second spring
Column 6 can have elasticity.The side of the piston 18 is connected to inner cavity one end of cylinder body 17 by second spring 19；So that second
