By adopting technique scheme, in the time wanting sleeved, first sleeve is set to and on axostylus axostyle, aims at corresponding scale, then make expansion block withstand sleeve pipe airbag aeration, withstand after sleeve pipe when discovery expansion block, scale has been offset, the other end of the relative air bag of expansion block is equipped with the slide block of axial slip, just can again aim at corresponding scale by moving axially axle sleeve, finally locate slide block by detent mechanism, so just make sleeve accurately be positioned on gas expansion shaft.
The utility model is further set to: described detent mechanism comprises the screw of 2 location expansion blocks and slide block, and described two screws are separately positioned on the axial two ends of the expansion block sidewall that can withstand slide block, are respectively equipped with corresponding tapped bore in described expansion block.
By adopting technique scheme, after sleeve is had good positioning, two screws are exposed at respectively outside sleeve, by rotary screw, slide block is secured in chute, slide block just can not slide like this, two screws are separately positioned on the axial two ends of the expansion block sidewall that can withstand slide block, and slide block is stablized regularly more.
The utility model is further set to: described rolling body comprises roller and rotating shaft, and described rotating shaft is erected in chute rotationally, and described roller is set in rotating shaft and respectively and contacts with chute diapire and slide block.
The utility model is further set to: the axial two ends of the relative axostylus axostyle of described chute communicate with the external world respectively.
By adopting technique scheme, in the time that slide block damages, can change slide block.
