Connecting rod for an impact member of an impact tool

A connecting rod for an impact member of an impact tool, the impact member comprising an impacting portion, a connecting portion axially opposite to the impacting portion and a radial flange between the impacting portion and the connecting portion, the radial flange including a first abutting surface facing the connecting portion, the impact member being insertable into the impact tool and detachably blocked by the impact tool, the connecting rod including :

• a rod body, including an axially opposing receiving end surface and an impacting end surface, a receiving end portion having the receiving end surface, and a holding portion between the receiving end surface and the impacting end surface, the receiving end surface recessed to form an assembling slot, the assembling slot including a second abutting surface disposed circumferentially;
• wherein when the connecting portion is inserted in the assembling slot, the first abutting surface abuts against the second abutting surface;
• wherein the receiving end portion and the holding portion are integrally formed of one piece, and the receiving end portion includes a horn shaped flange and is greater than the holding portion in diametrical dimension;
• wherein the assembling slot further includes a cylindrical opening which is open at the receiving end surface, a horn section extending from the cylindrical opening and a cylindrical section extending from the horn section and away from the receiving end surface, the horn shaped flange has the horn section thereinside, the horn section is smoothly curvedly enlarged outwardly toward the receiving end surface from the cylindrical section to the cylindrical opening, the horn section has the second abutting surface, and the second abutting surface is smooth;
• wherein receiving end portion further includes a groove formed circumferentially on an outer surface thereof and around the second abutting surface, the receiving end portion further includes a through hole radially communicated with the assembling slot and disposed between the receiving end surface and the second abutting surface, the rod body further includes a stuck member, the stuck member is integrally formed of one piece, the stuck member includes a C-shaped elastic buckling member received in the groove, a ball-shaped member and a straight member which is radially connected integrally with and between the C-shaped elastic buckling member and the ball-shaped member, the straight member is disposed through the through hole, the ball-shaped member is exposed within the assembling slot, and when the connecting portion is inserted in the assembling slot, the ball-shaped member is engaged on a side surface of the radial flange opposite to the first abutting surface.
