摘要： 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. By means of the resilient force of the resilient member, the pawl is inserted into the engaging hole of the inner sleeve.

摘要： A tying device including a seat body, a ratchet wheel, a driving member, a shaft and a detent member. A shaft is passed through the seat body and connected with the ratchet wheel. The driving member is pivotally connected with the shaft. The driving member can be wrenched to engage the detent member with different ratchets of the ratchet wheel so as to wind or release a tying belt connected with the shaft.
