Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features and the advantage of the present invention are further described, but this
Bright it is not limited to listed embodiment.
Seeing shown in Fig. 1-3, a kind of shallow interior stepped hole internal diameter special measurement measurer, including a hand holding handle
10 and the amesdial 12 that is fixed on described hand holding handle, described hand holding handle is opened on axial direction
It is provided with straight line adjustment hole 11, described straight line adjustment hole is provided with removable regulation and measures the mobile survey of position
Amount 20, described traverse measurement head is by the measurement of connected sliding part 13 with described amesdial 12
Bar 16 is connected, and described sliding part 13 is arranged in described straight line adjustment hole 11, and can described directly
Line adjustment hole moves into line position regulation, thus realizes regulating the position of described traverse measurement 20,
Described traverse measurement head is positioned at the lower side of described hand holding handle, and the lower side of described hand holding handle is provided with described
The fixation measuring head 21 that amesdial is connected, described fixation measuring head and described traverse measurement head are positioned at described
The same side of hand holding handle, when described traverse measurement head carries out position adjustments, can realize traverse measurement 20
And the distance between fixation measuring head 21, wherein traverse measurement 20 and the center of fixation measuring head 21
Line and the dead in line of described straight line adjustment hole.
Implementing, in the present invention, the bar 16 of measuring of described amesdial passes consolidating of a fixture
Being connected with described sliding part after determining portion 17, described sliding part is provided with the first measurement bar cramp tieholen 14,
Described fixed part is provided with the second measurement bar cramp tieholen, and described first measures bar cramp tieholen and second measures bar
Clamping screw 15 it is preset with on holes for clamping；Described fixture is fixedly mounted in described straight line adjustment hole.
Wherein, described fixture include a nahlock portion 18 being arranged on described hand holding handle upper side and
The locking member 22 threadeded with described nahlock portion, described locking member 22 is from the lower side of described hand holding handle
It is connected through described straight line adjustment hole 11 with described nahlock portion 18, the upper surface in described nahlock portion 18
