Description
Technical field
The utility model relates to a kind of specific purpose tool for tapping, relates in particular to a kind of tap wrench.
Background technology
The tap wrench that now uses has two kinds, for adjustable closely tap wrench and non-adjustable length apart from tap wrench.And these two kinds all exist certain defective: although adjustable closely tap wrench can a tap wrench install all kinds of models tapping-head it can not process distant hole internal thread, although and but non-adjustable length can be processed distant hole internal thread apart from tap wrench can not be regulated, the tapping-head of all kinds of models can not be installed at same tap wrench.
Chinese patent notification number CN201776534U discloses a kind of tap wrench, comprise handle, screw tap and tap chuck, one end of described tap chuck is fixedly connected with handle, the other end of this tap chuck offers a central inner hole vertically, the shank of this central inner hole shape and screw tap is adaptive, and the shank of described screw tap is removably installed and is fixed in the central inner hole of tap chuck.The distance of the tapping hole of this tap wrench is unadjustable equally.
The utility model content
The purpose of this utility model is to provide a kind of length adjustable, and the tap wrench that the tapping-head model is interchangeable is to solve the non-exchange problem of the irreconcilable tapping-head model of length that exists in the background technology.
To achieve these goals, the technical scheme of the utility model tap wrench is: a kind of tap wrench, comprise handle, connecting rod and chuck, one end of described connecting rod is fixedly connected with handle, the other end of connecting rod is fixedly connected with chuck, the scalable adjusting of described connecting rod, and the end face center of described chuck is provided with groove, sidewall at groove is provided with at least one screw, is provided with lock screw in the screw.The mentality of designing of this technical scheme is: connecting rod is designed to scalable adjustable type, makes its length adjustable; Adopt lock screw to be locked at the tapping-head of different model in the groove of chuck, this tap wrench both length is adjustable, again the tapping-head of replaceable Multiple Type.
As preferably, described connecting rod comprises outer tube and is located at inner tube in the outer tube, the internal diameter of outer tube and the external diameter of inner tube are adaptive, described outer tube wall is provided with through hole, and through hole is positioned at outer tube radially, and the sidewall of described inner tube is provided with a plurality of locating holes along its axially-aligned, locating hole is positioned at inner tube radially, cross-under has bolt in the through hole on one of them locating hole and the outer tube wall, and described outer tube is connected with handle, and described inner tube is connected with chuck.
As preferably, be equipped with screw on the two opposite side walls of the groove of described chuck, be provided with lock screw in the screw.
As preferably, be equipped with screw on the other two relative sidewalls of the groove of described chuck, be provided with alignment pin in the screw.Two alignment pins can be limited in tapping-head the center of chuck, and spanner concentricity in tapping is relatively good like this, are difficult for attacking screw bad.
As preferably, described handle is cylindrical steel, and handle is vertical with outer tube, and described outer tube is positioned at the centre position of handle.When tapping, above structure uniform force application, balance is better.
The beneficial effect of the utility model tap wrench is: this tap wrench both length is adjustable, again the tapping-head of replaceable Multiple Type.
