Abstract: A linear actuator orderly comprises an inner pipe, a middle pipe and an outer pipe, and the pipes are pivotally connected with each other. Each pipe is formed with at least three arc-shaped portions and three guiding portions, and the pipes abut against each other. The outer pipe is axially formed with a screw and two positioning rods that are passed through the middle pipe and the inner pipe, respectively. One end of each positioning rod is fixed with a pulling member, and one end of each pulling member is fixed to the inner pipe. The middle pipe is axially formed with a pushing post threaded with the screw. The pushing post and the middle pipe are pivotally disposed with a guiding wheel for rolling the pulling members, respectively. The pipes can be moved by the relative motion of the screw and the pushing post by cooperating with the guiding wheels and the pulling members, such that the pipes can be extended or retracted synchronously.

Abstract: An extension mechanism for an actuator comprises a telescopic assembly, a motor and an extension assembly. The motor and the extension assembly are respectively disposed in the telescopic assembly, and the motor is fixed at one end of the telescopic assembly. The extension assembly is connected by a plurality of X-shaped pivot members, and every two rods are pivotally connected together to form an X-shaped pivot member. The extension assembly is respectively connected to the sleeves. The motor is used to drive the extension assembly to extend and retract, thus causing the extension and retraction of the telescopic assembly.

Abstract: A removable pull handle device is adapted for use with a cabinet drawer formed with a handle mounting hole, and includes a face plate and a pull handle member having a key portion and a handle portion. The face plate includes a plate wall to be secured on the cabinet drawer so as to cover the handle mounting hole, and formed with a key hole for access into the handle mounting hole. The key hole and the key portion are configured such that, when the key portion is extended through the key hole, the pull handle member is rotatable relative to the face plate between a key inserting position, and a plate engaging position, where the pull handle member and the face plate cooperate to form a force exerting mechanism that permits application of a pull force to draw the cabinet drawer to an opened state.

Abstract: A mechanism for confining a flat flexible cable of an image scanner in position is provided. The flat flexible cable is electrically connected between a circuit board and a carriage and bends differentially with the movement of the carriage relative to the circuit board under a scanning platform. The mechanism includes a confining member disposed between a first portion of the flat flexible cable and the scanning platform for isolating the flat flexible cable from the scanning platform. The confining member changes states and bends differentially with the movement of the carriage relative to the circuit board under the scanning platform, and has a bending resistance greater than that of the flat flexible cable. Accordingly, the confining member is kept at least a certain clearance from the scanning platform while confining the first portion of the flat flexible cable thereunder.
