State the handle that one end at the top of foot bar close to fixed jaw is fixedly connected with L-shaped structure, the outside of the foot bar and separate fixation
One end of pawl has been fixed by screws fixed ring, and the top side detachable of the fixed ring is connected with dial gauge, the foot bar
Outside and sliding shoe is slidably connected between fixed jaw and fixed ring, the sliding shoe bottom is solid close to fixed jaw side
Surely it is connected with sliding jaw, one end of close fixed ring is fixedly connected with fixed bracket, the fixed bracket at the top of the sliding shoe
Reset spring is installed between fixed ring, the middle part corner of the handle is equipped with hinged pin shaft, and the handle passes through pin shaft
Rotatable lever is installed, one end of the lever is stuck in the outside of foot bar, and the lever connects with Slideslip outside foot bar
It connects.
It is in arc-shaped as a kind of preferred embodiment of the utility model, the bottom of the lever and close to the side of sliding shoe
Structure.
As a kind of preferred embodiment of the utility model, the measuring head of the dial gauge towards support bracket fastened side, and
The dial plate and axle sleeve of the dial gauge are rotatablely connected.
As a kind of preferred embodiment of the utility model, the inside and outside measuring surface of the fixed jaw and sliding jaw is circular arc
Face.
The utility model beneficial effect achieved is: it is novel that the utility model has the advantages of simple structure, practical, the present apparatus
The vernier caliper for not depending on standard detects workpiece, keeps chain link detection more convenient and economical, and it is big that material is applicable in the temperature difference, not by
Temperature influences, and not will cause substantial damage to cubing, does not influence cubing detection accuracy and service life, long service life, inspection
Frequency measurement time increases, and provides reliable basis to control of product quality is reinforced.
