Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-4, the inside of a kind of expansion positioning device, including shell, the shell is equipped with horizontally disposed expansion pin,
The expansion pin is flexibly connected inside the housing, and the outer wall movable sleeve of the shell is connected to expansion block, and the expansion block is located at interior of shell
Outer wall be in contact with the outer wall of expansion pin, the outer wall of described expansion pin one end is equipped with arcuate thread, the external spiral shell of the arcuate thread
Line is socketed with horizontally disposed connector, and the surface of the connector is equipped with water chestnut, and the expansion pin extends the outside of connector
And mounting hole is offered, the internal whorl of the mounting hole is connected with fastening bolt, and the expansion pin is set far from one end of connector
There is horizontally disposed stop mechanism, the stop mechanism includes the scotch of expansion pin one end welding, is set in the middle part of the scotch
There is threaded hole, the threaded hole internal screw thread is connected with arresting lever, and the middle part of the arresting lever is nibbled equipped with what is be meshed with threaded hole
Screw thread is closed, the both ends that the arresting lever is located at engagement screw thread are equipped with rubber layer, the inner wall of the rubber layer and the outer wall of arresting lever
Bonding, the surface of the shell is equipped with equally distributed anti-skid chequer, and the length of the fastening bolt is greater than the diameter of expansion pin.
In the present embodiment, when work, by the way that two holes are put into concentric position, shell 1 is put into inside two holes, by arresting lever
