Abstract: A hinge for a cellular phone that has a cover and a base comprises an inner sleeve, an outer sleeve and a spring. The spring is mounted between the inner sleeve and the outer sleeve and provides a torsion force to open the cover. A layer of buffering gel is applied the outer surface of the inner sleeve between the inner sleeve and the outer sleeve to damp the opening rate of the cover so that the pivoting device can keep a wire between the cover and the base from breaking.

Abstract: A device for coupling a wheel to a golf club carrier includes a sleeve member axially and rotatably passed through the axle of the wheel. A head portion with a tongue is formed at an end of the sleeve member. Two lugs parallelly extend from the free end of the leg of the golf club carrier. A fixing rod has a first end connected to the leg of the golf club carrier near the free end of the leg and a second end passing through the head portion of the sleeve member into the sleeve member. A plurality of radial ribs extend outwardly near the first end of the fixing rod and are correspondingly fitted into a plurality of radial grooves formed in the head portion of the sleeve member so as to prevent the fixing rod from rotation relative to the sleeve member when the fixing rod is received in the sleeve member.
