Description

Tap sleeve anchor clamps

The utility model relates to the sleeve anchor clamps, specifically a kind of tap sleeve anchor clamps.

In the prior art, the sleeve anchor clamps generally are that fixing part one end is the lock-joining part that an outer rim has the proper range screw thread, the central leading portion of this lock-joining part has the disposal area of one group of clamping pawl, and centre extension downwards is provided with a grooving among this disposal area, in this grooving, be provided with a shape tensile spring, two arm of forces of this shape tensile spring penetrate respectively in the set perforation in described clamping pawl bottom, make described clamping pawl keep relative open configuration because of the tension force effect of tensile spring, outer rim is provided with an arcuation inclined-plane at the relative top of described clamping pawl, in it, then be provided with relative V word clamping notch, in addition, be hollow tubular at lock-joining part interlocking one, the endoporus epimere is a screw thread, hypomere has the adjustment folder bundle part of scalene cone, when adjusting this adjustment folder bundle part, outer rim arcuation inclined-plane, clamping pawl top is subjected to the displacement effect of the scalene cone in this adjustment folder bundle part, and distance is changed, thereby tap that can the clamping different size; In addition, in the fixing part termination of the sleeve anchor clamps other end, be provided with a square trepanning, and be provided with the steel ball locating slot at the inwall of this square trepanning, this square trepanning and pneumatic tool front end connect as one, and can attack the processing of hinge screw thread to workpiece.Its weak point is: when attacking the hinge screw thread with pneumatic tool, because of the reaction force of rotation, and make the tightness of this adjustment folder bundle part revolve tighter and tighter, therefore must just can unscrew this adjustment folder bundle part with instrument, to reach the purpose that unloads or change tap, use very inconvenient.

In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide a kind of tool using that do not need can unscrew adjustment folder bundle part easily, is convenient for changing the tap sleeve anchor clamps of tap.

To achieve these goals, the technical solution of the utility model is: comprise the sleeve anchor clamps, lock-joining part, the clamping pawl, adjust folder bundle part and stop sliding sleeve, wherein fixing part one end of sleeve anchor clamps is the screwed lock-joining parts of outer rim, the central epimere of described lock-joining part is provided with a disposal area, symmetry is installed one group of clamping pawl in the described disposal area, and under mediad, extend and be provided with a grooving, one shape tensile spring is installed in described grooving, two arm of forces of described tensile spring penetrate respectively in the set perforation in clamping pawl bottom, outer rim has an arcuation inclined-plane at the relative top of described clamping pawl, be provided with relative V word clamping notch in the inboard of each clamping pawl, the described lock-joining part adjustment folder bundle part that is hollow tubular that spins, the endoporus hypomere of described adjustment folder bundle part is provided with screw thread, its epimere is a scalene cone, be provided with a square trepanning on the end face of sleeve anchor clamps other end fixing part, the inwall of described square trepanning is provided with the steel ball locating slot, it is characterized in that:

Outer rim is provided with the chute that is axially parallel in the stage casing of described sleeve anchor clamps, described chute place is provided with the stop sliding sleeve of an endoporus stage casing tape spool to parallel raised line, described raised line matches with the set chute in sleeve anchor clamps stage casing, bore end is provided with internal tooth portion in described stop sliding sleeve, described adjustment folder bundle part end outer rim is provided with the outer toothed portion that matches with described internal tooth portion, and the endoporus leading portion of described stop sliding sleeve is equipped with a spring; To adjust folder bundle part and revolve a suitable tightness, passing described stop sliding sleeve makes its internal tooth portion match with the outer toothed portion of adjusting folder bundle part, so adjusting folder bundle part is restricted and can't be screwed by external force or loosening again, then in the process of attacking the hinge screw thread, the tightness of this adjustment folder bundle part is remained unchanged, pass the outer toothed portion that makes its internal tooth portion and adjust folder bundle part backward when separating at the stop sliding sleeve, do not need can unscrew easily under the tool using adjustment folder and restraint part in order to changing tap, the spring that the endoporus leading portion of described stop sliding sleeve is installed can make stop slide at ordinary times and all restraint the part interlock with the adjustment folder.

The utlity model has following advantage:

In the process of attacking the hinge screw thread, the tightness of adjusting folder bundle part remains unchanged, the stop sliding sleeve makes its internal tooth portion separate with the outer toothed portion of adjusting folder bundle part when passing backward, then need not tool using and can unscrew adjustment folder bundle part easily, be convenient for changing tap, laborsaving, save time, easy to use and efficient is high.
