Abstract: A tire inflation device includes a bottle having a valve on a top end of the bottle and a top part is mounted to the top end of the bottle. The top part has a frame having a U-shaped groove and the valve extends through top part and located in the frame. A block is movably engaged with the U-shaped groove and has a curved path defined therethrough. A first end and a second end of the curved path are respectively connected with a tube and the valve. An operation member is pivotably connected to the frame so that when pivoting the operation member, the press end of the operation member pushes the block to move along the U-shaped groove and the valve is pushed by the block so that the pressurized air is released via the path and the tube.

Abstract: A warning device includes a sign connected with a first end of a cable and a second end of the cable passes a pulley, and is connected to a garage door, so that when the garage door is opened, the sign is lowered to a desired height and seen by the driver to stop the car.

Abstract: A cleaning device for oil dipsticks includes two first parts which are pivotably connected with each other at a mediate portion thereof and a torsion spring is located between the two first parts so that the two handles are wide opened from each other. Each first part has a clamping portion which can clamp the device to a part in the engine room. Each handle has a slot defined therethrough. Two second parts are respectively connected to the two handles, wherein each second part has one end flexibly connected to the handle corresponding thereto. A cleaning member is connected to two respective insides of the two second parts. The two second parts can be pushed toward via the slots to wipe the oil dipstick between the two ends of the cleaning member while the first parts still clamp to the part.

Abstract: A cleaning device for oil dipsticks includes two parts pivotably connected with each other and each part includes clamping portion at a first end thereof and a handle at a second end thereof. A cleaning member is connected to the two handles. The user pivots the two handles toward each other to wipe the oil on the oil dipstick by the cleaning member and the device can conveniently clamps to any part in the engine room when not in use.

Abstract: An unclogging device includes a support member securely mounted to the can and a cap rotatably mounted to the support member. The cap includes two flexible portions on the peripheral wall thereof and first and second protrusions extend from each of the flexible portions. The support member includes two first notches for engaging one of the first protrusions and two second notches which are deeper than the first notches so as to allow the first protrusions to be moved therein after the support member is rotated an angle relative to the cap. By the arrangement, the users have rotate the support member together with the can relative to the cap before the nozzle on the can is pushed by the cap to eject the pressurized air in the can from the nozzle to clean the clogged drains.

Abstract: A drain cleaner includes a casing having a tube engaged with an opening in the first end of the casing and the tube has a shrink opening on a top surface thereof. A high pressure can is received in the casing and includes a valve which is located in alignment with the shrink opening of the tube. A rod movably extends through a second end of the casing so as to push the can to let the valve be activated by the shrink opening and a high pressure is generated through the tube.
