Abstract: An oil filling device includes an oil filling funnel, an extendable tube assembly, a direction adjustment assembly, and a coupling assembly. The oil filling funnel is mounted to a first end of the extendable tube assembly. The extendable tube assembly has a second end mounted to the direction adjustment assembly. The direction adjustment assembly is mounted to the coupling assembly that is attachable to an oil filling hole of an engine. The direction adjustment assembly enables adjustment of the direction of the extendable tube assembly and the oil filling funnel with respect to the engine, while the extendable tube assembly allows the oil filling funnel to be selectively moved toward or away from the oil filling hole. Thus, the oil filling device may accommodate various heights and angles of oil filling hole of engine and allows filling of oil into the engine to be conducted in a smoother manner.

Abstract: A multi-purpose large capacity pump includes a cylinder having top and bottom ends closed by a top lid and a bottom lid. The top lid is provided with an inlet port that is in communication through a first one-way valve with an interior space of the cylinder. The bottom lid includes a second one-way valve in communication with the interior space of the cylinder. An output tube connects between the second one-way valve and an outlet port of the top lid. A protection enclosure is set around an outer circumference of the cylinder and a base is provided to fix and support the bottom end of the cylinder. A pull bar extends through the top lid into the cylinder to allow an inner end thereof to couple to a piston. The pull bar has an outer end to which a handle is mounted.

Abstract: A hand-operated vacuum pulling device includes a shank, over which a backward ram is slidable fit. The shank has a front end to which a suction cup is attached and a rear end to which a handgrip defining a cylinder and having a pressure relief seat is attached. The pressure relief seat forms a ram stop at a joint thereof with the shank. The handgrip has a rear end to which a ring-shaped cover assembly is attached. The piston assembly is manually operable to induce a vacuum inside the cylinder. And then, the ring-shaped cover assembly can be manually operated to pull the piston assembly backward for repeated operation of the piston assembly to thereby make a spring contained in the piston assembly stiffer and increase the suction power of the suction cup. The backward ram can be quickly moved backward to impact the ram stop for improving pulling effect.

A collar receives a ball end of a bar therein and is attached to the pillar. The ball-ended bar is coupled to a threaded rod, which extends through an internally-threaded locking knob and received into the attaching seat to be secured by a nut. With such an arrangement, one of the suction cups can be attached to a planar fixture surface, while the other suction cup can be used to hold an article and is orientation adjustable in any direction.

Abstract: A hand/pneumatics dual operation vacuum pulling device includes an elongate shank and a slidable backward ram fit to the shank. The shank has an end to which a suction cup is attached. The shank has an upper end to which a handgrip having a pressure relief seat is mounted. A ramp stop section is formed below the pressure relief seat. The handgrip can selectively and switchably couple with a hand-operating pump piston to form a hand-operating vacuum pulling device, or couple with a pneumatic operation seat to form a pneumatically-operating vacuum pulling device. For hand operation or pneumatics operation, the vacuum pulling device is allowed to easily switch between the two modes according to the availability of power supply and the site of use, thereby achieving an excellent device for one device having two ways of use.

Abstract: An automatic alert device is provided for a suction cup, including a pump and a suction cup positionable on an object to be handled. The pump is operable to drive air out of the suction cup thereby inducing suction force on the object to be handled. When the suction cup gradually loses the suction force, a plunger of the pump gets moved out of the pump. When the outward movement of the plunger reaches a preset extent, the alert device that includes a warning light and an audio alert is activated to cause the warning light and the audio alert to give off warnings of light and sound respectively. Thus, an operator can be immediately notified of the situation of losing suction force for taking remedial operation to get the suction force back to the desired level.
