With the above pressure relief structure, the adaptor joint can stay at any radially displaced position relative to the fixed retainer.

A floating joint and retainer connection device includes a fixed retainer internally defines a receiving space; an adaptor joint having an end extending through the receiving space to an outer side of the fixed retainer and an axially limiting section formed near another end; a fixing element fitted on the adaptor joint and located outside the fixed retainer for limiting the adaptor joint from moving axially while allowing the adaptor joint to displace radially relative to the fixed retainer; a rolling assembly disposed adjoining the fixed retainer; and a spring located in the receiving space and fitted on the adaptor joint with two ends pressed against the axially limiting section and the fixed retainer or the rolling assembly. When the rolling assembly rolls to displace radially relative to the fixed retainer, a radial frictional force produced by a normal force applied by the spring to the fixed retainer is reduced.

A rotating shaft device includes a base, a rotation member, a slide member, a supporting member, and a linkage unit. The rotation member is rotatable relative to the base between a first position and a second position. The slide member is slidable relative to the base. The supporting member is pivotable relative to the base between an initial position and a supporting position. The linkage unit is convertible between a folded state and an expanded state. When the rotation member is in the first position, the linkage unit is in the folded state and the supporting member is in the initial position. When the rotation member is rotated to the second position, the slide member is urged by the rotation member to slide and to convert the linkage unit into the expanded state, and the supporting member is urged by the linkage unit to pivot to the supporting position.

Rotating shaft device

A rotating shaft device includes a base, a rotation member, a slide member, a resistance-providing member, a supporting member, and a linkage unit. The rotation member is rotatable relative to the base between a first rotation position and a second rotation position. The slide member is slidable relative to the base between a first slide position and a second slide position. The resistance-providing member prevents the slide member from moving toward the first slide position when the slide member is in the second slide position. The supporting member is movable relative to the base between an initial position and a supporting position. The linkage unit is convertible between a folded state and an expanded state. When the rotation member is in the first rotation position, the slide member, the linkage unit, and the supporting member are respectively in the first slide position, the folded state, and the initial position.

A floating joint and retainer connection structure includes a hollow fixed retainer having one closed side formed with a through opening and radially extended sliding slot pairs; an adaptor joint having a pipe connecting and a joining section connected to the retainer and a male coupler, respectively; a first sliding member having an opening fitted on the pipe connecting section, a first slide movably engaged with the sliding slots, and a front guiding recess; a second sliding member having a bore fitted on the pipe connecting section and shaped for slidably engaging with the guiding recess; and a retaining ring fitted on the pipe connecting section and attached to the second sliding member to limit the first and second sliding members from moving axially. With the first and second sliding members, the adaptor joint can translate to correct a radial fit tolerance and be conveniently assembled to the fixed retainer.

A rotating shaft device includes a base, a rotation member, a slide member, a supporting member, and a linkage unit. The rotation member is rotatable relative to the base between a first position and a second position. The slide member is slidable relative to the base. The supporting member is slidable relative to the base between an initial position and a supporting position. The linkage unit is convertible between a folded state and an expanded state. When the rotation member is in the first position, the linkage unit is in the folded state and the supporting member is in the initial position. When the rotation member is rotated to the second position, the slide member is urged by the rotation member to slide and to convert the linkage unit into the expanded state, and the supporting member is urged by the linkage unit to slide to the supporting position.

A rotation device includes a base seat, an axle unit and a lock unit. The axle unit extends into the base seat. The lock unit includes a lock plate that is sleeved on the axle unit, and a lock member that is disposed on the base seat. The lock plate is formed with a first lock groove. The lock member has a lock portion that is operable to move into the first lock groove. The lock plate is locked by the lock portion of the lock member when the lock portion moves into the first lock groove, so that the axle unit and the lock plate are not rotatable relative to the base seat.
