Abstract: A pull handle structure includes a carrier mounted on a first object, a pull handle movably assembled to the carrier, and a limiting section located on the pull handle for connecting to, interfering with or engaging with a second object. By operating the pull handle to move the carrier, the first object can be engaged with or separated from the second object. Therefore, the pull handle structure has the advantages of being securely lockable in place and operable in an easy, convenient, effortless and quick manner.

Abstract: A roller structure and a manufacturing method thereof are introduced. The roller structure includes a roller rotatable about an axial portion; a bush with an end disposed to an end of the axial portion and has a first stop portion positioned proximate to one side of the roller and another end having an engaging portion coupled to a load; and a second stop portion disposed to the other end of the axial portion and positioned proximate to the other side of the roller such that the roller rotates between the first stop portion and the second stop portion. Hence, the roller structure and the manufacturing method thereof provide a modularized roller structure for carrying a load, effectuate modularized assembly and production, enhance assembly efficiency, attain structural streamlining, and cut costs.
