Abstract: An extensible supporting strut including an inner sleeve and an outer sleeve. Each end of the supporting strut has a supporting section. The inner sleeve is formed with several engaging holes axially arranged at equal intervals. A base seat is connected between the outer sleeve and the inner sleeve. Two locking lugs laterally extend from the bottom of the base seat for locking the outer sleeve. The base seat has two symmetrically extending sideboards each having a head section. An engaging member and a handle are pivotally disposed between the head sections of the sideboards. A pivoted end of the handle is formed with a stepped protruding push section. The engaging member is pivotally disposed in the handle and has a pivoted end formed with a toothed section. The middle sections of the sideboards are formed with a pair of aligned through holes. A fixing pin is passed through the through holes, a resilient member and a pawl.

Abstract: A belt reel for fastening goods on a truck includes an axle extending through a main frame and a lever to pivotally mount the main frame and the lever to each other. The axle includes two opposite ends each having a ratchet wheel mounted thereto between the main frame and the lever and rotated with the axle. A slot is diametrically defined in the axle for allowing a belt extending through the axle. The main frame has a stop plate slidably mounted therein and selectively engaged to the ratchet, and the lever has a pawl slidably mounted therein. The pawl is engaged to the ratchet for driving the axle to reel the belt and separated from the ratchet for releasing the strain of the strained belt.
