Abstract: A management method for a cutting tool of a machine tool is provided. A user host imports a graphical data of a workpiece and a cutting tool database into CAM, and a user may select cutting tools to establish a complete machining process. T codes are replaced with electronic tags. Before executing a machine code comprising the electronic tags, the machine tool re-scans the cutting tools assembled at a tool turret and updates cutting tool arrangement information to ensure that the tool turret is equipped with the cutting tools used in the machining process. When the machine tool stores the electronic tags, a ready message is displayed for reminding an operator. When the electronic tags are not stored, the current storage location of a cutting tool lacked in the machining process or a warning message is displayed at the operation interface for reminding the operator.

Abstract: A foldable vehicle includes a skeleton, a coupling member and a latch unit. The skeleton includes a base frame, front and rear supporting frames pivoted to the base frame, a pivoting member pivoted to the front and the rear supporting frames and having a first crossbar, and a second crossbar provided on one of the front and rear supporting frames. The coupling member is fixed to one of the first and second crossbars and is releasably coupled to the other of the first and second crossbars. The latch unit is mounted on the coupling member for preventing uncoupling between the coupling member and the other of the first and second crossbars.

Abstract: A stroller includes pivotally connected wheel-carrying front and rear legs, and two handle tubes pivoted to the front and rear legs via a pair of joints in such a manner that the handle tubes and the front and rear legs are movable relative to one another between a storage position, in which, the front legs and the handle tubes are foldable onto the rear legs and a position of use, in which, the front legs and the handle tubes are moved away from the rear legs. Two locking units are independently operated so as to prevent untimely folding of the front legs and the handle tubes onto the rear legs when in the position of use.

Abstract: A stroller includes a stroller frame, a wheel unit mounted on the stroller frame, a resistance providing unit mounted on the stroller frame, a revolution sensor mounted on the stroller frame adjacent to the wheel unit so as to detect revolution of the wheel unit and so as to generate an electrical signal each time one revolution of the wheel unit is detected, and a counter mounted on the stroller frame and connected to the revolution sensor so as to receive the electrical signal from the revolution sensor and so as to count the number of the revolutions of the wheel unit.

Abstract: A stroller includes a folding mechanism and a basket support frame. The folding mechanism has front and rear folding parts interconnected pivotally for moving toward or away from each other to a folded position or an unfolded position. The front folding parts are connected to a front frame. The rear folding parts are connected to rear and handle frames.

Abstract: A foldable stroller includes a pair of hollow handle tubes, a pair of front legs, a pair of plungers, and a pair of actuating members. Each handle tube has a lower end with an enlarged portion. Each front leg has an upper end with a rearward enlarged part. When the handle tubes are moved from a first folded position to a first stretched position, the enlarged portion of the respective handle tube moves from a first angular position where it does not overlap with the rearward enlarged part of the respective front leg, to a second angular position where it overlaps with the rearward enlarged part. Each locking member has a hooked portion mounted on the rearward enlarged part of the respective front leg, and a rear hooking portion mounted on the enlarged portion of the respective handle tube. Each plunger has actuated and coupling ends, and a middle portion coupled to the rear hooking portion of the respective locking member. Each actuating member has actuating and linking ends.

Abstract: A foldable stroller includes a pair of rear legs, a pair of hollow handle tubes, a pair of front legs, a pair of bracing rods, a pair of locking members, a pair of plungers, a pair of actuating members, and a pair of biasing members. Each handle tube has a lower end with a forward enlarged portion. Each front leg has an upper end with a rearward enlarged portion. When the handle tubes are moved from a folded position to a stretched position, the forward enlarged portion moves from a first angular position where the forward enlarged portion overlaps slightly with the rearward enlarged portion, to a second angular position where the forward enlarged portion overlaps extensively with the rearward enlarged portion. Each locking member has a hooked portion disposed on the rearward enlarged portion and a rear hooking portion that is pivotally mounted on the forward enlarged portion, and that engages the hooked portion when the forward enlarged portion is in the second angular position.

Abstract: A leg exerciser includes first and second legs, and a stretcher member. The first and second legs are mounted pivotally to each other at a first pivot. Each of the first and second legs has upper and lower leg portions which are disposed respectively at two opposite sides relative to the first pivot. The stretcher member is disposed to link the first upper leg portion and the second upper leg portion in such a manner that when the first and second lower leg portions are in a straddled position, the stretcher member is in a stretched position and, when the first and second lower leg portions are in a folded position, the stretcher member is in a non-stretched position.
