It is fixed on the tap holder by the first fixed knob；Measuring scale, the survey are additionally provided on the outside of the Fixing shrink ring
Gage is arranged on the Fixing shrink ring by the second fixed knob, and the measuring scale is arranged vertically with Fixing shrink ring.
Further scheme is that through-hole is provided on the outside of the Fixing shrink ring, and the measuring scale is set through through-hole activity
It sets on the Fixing shrink ring；The measuring scale includes scale section and extended segment, and scale area is provided in the scale section and is carved
Degree section is positioned close to one end of the through-hole, and the extended segment is positioned close to one end of the screw tap.
Further scheme is that the scale section is provided with a grade item, the scale area and the shelves close to one end of through-hole
The joint of item is set as " 0 " scale.
Further scheme is that one end on the tap holder far from screw tap is provided with extension bar, the extension bar
Through tap holder and extension bar is arranged perpendicular to tap holder.
The tapping depth measuring device provided in above-mentioned technical proposal, utilizes the knot of tap holder, screw tap and measuring scale
It closes and uses, can directly measure tapping depth, so that measurement is more accurate quick, while can also realize and first determine that tapping is deep
Degree is carrying out screwing operation, flexibly and easily, is not required to difference and calculates, reduce measurement error.The utility model tapping depth measurement dress
It sets, structure is simple, and it is flexible and convenient to use, tapping depth can be quick and precisely measured, and can first determine tapping depth, later
Screwing operation is carried out again, and use is portable, and flexibility ratio is high；It can effectively solve low efficiency existing in the prior art, the big problem of error.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of tapping depth measuring device described in the utility model.
In figure: 1, tap holder；2, screw tap；3, Fixing shrink ring；31, the first fixed knob；32, the second fixed knob；4,
Measuring scale；41, shelves item；42, scale section；43, extended segment；5, extension bar；6, workpiece is measured.
Specific embodiment
In order to which the purpose of this utility model and advantage is more clearly understood, with reference to embodiments to the utility model into
Row illustrates.It should be appreciated that following text is only used to one or more of specific embodiments of description the utility model,
Considered critical is not carried out to the protection scope that the utility model is specifically requested.
As shown in Figure 1, a kind of more specifically scheme is, a kind of tapping depth is surveyed for technical solution that the utility model is taken
Device is measured, including tap holder 1 and screw tap 2, the screw tap 2 are detachably arranged at the lower end of the tap holder 1, the tapping
Length direction sliding on collet 1 along tap holder 1 is provided with Fixing shrink ring 3, and the Fixing shrink ring 3 passes through the first fixed knob
31 are fixed on the tap holder 1；The outside of the Fixing shrink ring 3 is additionally provided with measuring scale 4, and the measuring scale 4 passes through the
Two fixed knobs 32 are arranged on the Fixing shrink ring 3, and the measuring scale 4 is arranged vertically with Fixing shrink ring 3；First fixed knob
For Fixing shrink ring to be fixed on tap holder, the position of Fixing shrink ring is according to the length of screw tap (when measuring scale length is fixed)
It determines, i.e. the lower end of guarantee measuring scale is concordant with the lower end of screw tap to be arranged, and second fixed knob is surveyed for fixed after a measurement
The position of gage, convenient for reading scale.
Specifically, the outside of Fixing shrink ring 3 is provided with through-hole, and the measuring scale 4 is movably arranged on described solid through through-hole
