摘要： An air chuck includes a body and a valve core interface. The body includes output, interface, and input ports. The body defines a first passageway that extends between the output and interface ports. The input port defines a second passageway that is in fluid communication with the first passageway. The valve core interface is slidably coupled with the body and is slidable between extended and retracted positions. The valve core interface includes a shaft and a knob. The shaft includes proximal and distal ends. The distal end is at least partially disposed in the first passageway. The knob is coupled with the proximal end of the shaft. The shaft is rotatably coupled with the body and is selectively rotatable in either tightening or loosening directions via the knob. The distal end of the shaft comprises a grasping feature that is configured to grasp a valve core of a valve stem.

摘要： A chuck includes a plurality of master jaws 20 that slide in the radial direction in the front surface of a body 10 in conjunction with slide of a plunger 40. The body 10 has a housing chamber 11 communicating with a plurality of keyways 13. The plunger 40 is fitted in the housing chamber 11. Each of the master jaws 20 includes a narrower part 21 and a wider part 22 fitted into an associated one of the keyways 13, and a wedge 23 connected to the plunger 40. The wider part 22 has a flat wider sliding surface 22b radially outside the wedge 23. Each of the keyways 13 has a wider slid surface 14.
