One specific scale；
One mounting blocks, the mounting blocks outside is provided with a mounting hole, and the mounting blocks are provided with a regulation by upper table downwards
Hole, the adjustment hole is connected with mounting hole；
The installation end grafting of the lever meter is simultaneously installed in the mounting hole, and the set screw adjustable type is installed on institute
State in adjustment hole, the gauge head and part measuring staff of the lever meter are located at the lower section of the cuboid support body through the holding tank；
When shallow bore hole is measured, the set screw carries out Primary Location, the regulation spiral shell in passing through a location hole mutually fitted
Silk regulation depth rotates gauge head, the set screw and the gauge head is contacted with the medial surface of surveyed shallow bore hole respectively.
In the embodiment of the utility model one, the center of the holding tank and each location hole is in a straight line.
In the embodiment of the utility model one, described shallow bore hole measurement apparatus also include a calibrating plate, described for calibrating
Lever meter, makes the initial scale of the lever meter be 0.
In the embodiment of the utility model one, the calibrating plate is a disk, and there are a circular hole, the circle in the disk middle part
Hole is used for the calibration of the lever meter.
The utility model has the advantages that：Shallow bore hole measurement apparatus of the present utility model, can accurately measure the size of shallow bore hole,
Including internal diameter size etc., simple structure is easy to use, and certainty of measurement reaches 0.01mm, meets the shallow bore hole chi of existing workpiece
Very little measurement demand, improves measurement efficiency and certainty of measurement.
Brief description of the drawings
The utility model is further explained with reference to the accompanying drawings and examples.
Fig. 1 is the shallow bore hole measurement apparatus structural representation of the utility model embodiment.
Fig. 2 is the shallow bore hole measurement apparatus explosive view of the utility model embodiment.
Structural representation when Fig. 3 is the shallow bore hole measurement apparatus calibration of the utility model embodiment.
Wherein,

Specific embodiment
The explanation of following examples is, with reference to additional schema, to be used to illustrate the specific reality that the utility model may be used to implement
Apply example.The direction term that the utility model is previously mentioned, for example " on ", D score, "front", "rear", "left", "right", " top ", " bottom "
Deng being only the direction with reference to annexed drawings.Therefore, the direction term for using is to illustrate and understand the utility model, rather than
It is used to limit the utility model.
Embodiment, as shown in Figure 1 and Figure 2, a kind of shallow bore hole measurement apparatus, including a lever meter 1, a set screw 2, are adjusted
Section screw 3, a dial framework 4.
The dial framework 4 includes a cuboid support body 41, a mounting blocks 42.The cuboid support body 41 is provided with multiple location holes
411 Hes
One holding tank 412, each location hole 411 represents a specific scale.Holding tank 412 and each location hole 411
Center in a straight line.The outside of mounting blocks 42 is provided with a mounting hole 421, and mounting blocks 42 are provided with an adjustment hole by upper table downwards
422, adjustment hole 422 is connected with mounting hole 421.
The grafting of installation end 13 of lever meter 1 is simultaneously installed in mounting hole 421, and the installation end 13 is one raised.Set screw 3
