摘要： A versatile air-valve connecting device includes two valve connectors and a rotator. The two valve connectors each have an air inlet. The rotator has a cam including a major diameter and a minor diameter and has an air hole. The rotator normally contacts the two valve connectors with the minor diameter so that the two valve connectors are in a relaxed state, and when the rotator is rotated to have the major diameter contacting the two valve connectors, the two valve connectors are slightly deformed under compression and turned into a use state for connecting a valve, where the air hole is communicated with the air inlet of one of the valve connector while the air inlet of the other valve connector is closed by the cam portion into airtightness.

摘要： An air pump that measures an air pressure including a base, a one-way valve, a pump pipe, a piezometer, a scale plate, a cylinder, a piston, and a driving stem. The base has a chamber room. The one-way valve has an inlet chamber and a vent. The scale plate has an air-guiding hole so that a cylinder hole of the cylinder is communicated with the air-guiding hole. A piston is driven to pump gas in the cylinder hole, thereby forcing the gas to enter the inlet chamber, rendering the vent to deliver the gas unidirectionally, and allowing the scale plate to display an air pressure value.

摘要： A dual-purpose safety baby carrier includes a seat having armrests and a bottom to which a cover defining a receiving chamber is mounted. Upper and lower positioning sections are mounted to a back of the seat. A control bar is movable along the upright tubes between a position where a push key of a safety switch engages the upper positioning section to allow a wheel frame carrying wheels to be retracted into the receiving chamber for serving as a safety seat and a position where the push key engages the lower positioning section to allow the wheel frame to be expanded to form a stroller. The safety switch also includes a push button biased by a spring for locking the push key in position of engaging the upper or lower positioning section. A securing structure includes coupling members mounted to the seat for coupling a seat belt.

摘要： An inversion table includes a supporting stand, a tilt inversion mechanism and an operating unit. The tilt inversion mechanism includes an inversion unit including a support table assembly which is pivotally disposed on the supporting stand, and an extension assembly which is coupled with and extends from the support table assembly downwardly. A feet holding unit includes a front feet holding assembly securely and non-pivotably disposed on a lower portion of the inversion unit, and a rear feet holding assembly pivotably and movably connected to the inversion unit. The operating unit includes an operating assembly operably coupled with the front feet holding assembly, and is rotatable about a rotating axis at the front feet holding assembly to actuate the rear feet holding assembly to rotate and move toward the front feet holding assembly. In an inversion state, the users feet is firmly held on the front feet holding assembly.
