Furthermore, the diameter of the openings at the two ends of the straight cylinder part is smaller than the inner diameter of the straight cylinder and larger than the diameter of the percussion bit, the two ends of the interior of the straight cylinder part are respectively provided with a gasket A and a gasket B which are movably connected, the diameters of the gasket A and the gasket B are the same,
furthermore, the opening of the extension part is polygonal or circular.
Further, the percussion drill comprises a part of the fixed stop block, which penetrates through the straight barrel part and extends to the extension part.
Further, the diameter of the extension part is gradually reduced to be the same as the diameter of the opening of the straight cylinder part along the length direction.
Furthermore, the fixed stop block is annular, and the outer diameter of the fixed stop block is smaller than the inner diameter of the straight cylinder part and larger than the diameter of the opening of the straight cylinder.
Further, the part of the percussion drill bit which is not sleeved into the stainless steel pipe is in a pitch-rectangular pulse shape.
By adopting the technical scheme, the method has the following beneficial effects:
the utility model has the advantages of whole simple structure, high durability and convenient use, keep away from telescopic one end with percussion bit and install on the percussion drill, when needs use, in screw nail or draw the screw to pack into the extension pipe, open inside the impact force that the percussion drill power utilized the percussion drill squeezes into the wall body of having punched the hole in advance, squeeze into the in-process in the wall gradually again, along with user's direction extrusion spring hard, percussion bit impels to the other end of extension pipe gradually, make screw nail or draw the screw of exploding expose and squeeze into the internal portion of rifle from the extension pipe gradually, whole installation process time is short, high efficiency, and the shape of extension opening part is not fit for drawing the screw nail and the screw nail of exploding, it is effectual to fix a position.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Example 1:
as shown in fig. 1-5, an impact drill sleeve comprises a stainless steel tube 1 and an impact drill 2, wherein a fixed stop block 4 is integrally connected to the impact drill 2, a portion of the impact drill 2 including the fixed stop block 4 is disposed inside the stainless steel tube 1, the stainless steel tube 1 includes a straight tube portion 11 and an extension portion 12 integrally connected to one end of the straight tube portion 11, an extension opening 13 and a straight tube opening 14 are respectively disposed at two ends of the stainless steel tube 1, and a portion of the impact drill 2 disposed inside the stainless steel tube 1 is sleeved with a spring 3.
In addition, the diameter of the opening at the two ends of the straight cylinder part 11 is smaller than the inner diameter of the straight cylinder and larger than the diameter of the percussion bit 2, a gasket a5 and a gasket B6 which are movably connected are respectively arranged at the two ends of the inner part of the straight cylinder part 11, the diameter of the gasket a5 is the same as that of the gasket B6, the opening of the extension part 12 is polygonal or circular, the percussion bit 2 comprises a part of a fixed stop 4 which penetrates through the straight cylinder part 11 and extends to the extension part 12, the diameter of the extension part 12 is gradually reduced to be the same as that of the opening of the straight cylinder part 11 along the length direction, the fixed stop 4 is annular, the outer diameter is smaller than the inner diameter of the straight cylinder part 11 and larger than that of the opening 14 of the straight cylinder, and the part of the percussion.
The utility model discloses when carrying out concrete use, screw nail or inflation screw are packed into extension 12 department, and to the wall body position that needs the installation, place the sleeve perpendicularly and contact the wall body, open percussion bit 2's power and squeeze into the wall body of beating the hole in advance along with the impact force in, compare with current manual hammer improvement, and constructor can according to percussion bit 2 not embolia the part of nonrust steel pipe 1 roughly judge squeeze into the rifle internal portion how much.
