20100123109 | Extension rod unit - An extension rod unit includes an outer tube with an inner tube retractably inserted thereto and a ratchet unit is connected to the open top of the outer tube. The ratchet unit includes a connection member and a lever. The connection member includes two side panels and each have a first lug extending therefrom. The lever has two second lugs and the shaft extends through the first and second lugs so as to pivotably connect the lever to the connection member. Two ratchet gears are located between two sets of first and second lugs. A slot is defined axially through the shaft. A driving member has a first end fixed to the fixing part and a second of the driving member extends through the slot of the shaft and is located beyond the outer tube. By pivoting the lever, the inner tube can be moved relative to the outer tube. | 05-20-2010 |
20100192336 | Belt Pincher - A belt pincher for holding a belt is disclosed. A loop made of the belt is constrained on a constrainer. The belt pincher has two opposite sidewalls. A restricting rod is fixedly interposed between the two sidewalls. A rotating arm is pivotally interposed between the two sidewalls. One end of the rotating arm is formed with an acting part. One end of the belt winds around the acting part and urges against the restricting rod. When the belt is pulled by the reaction of a constrained object, it pulls the rotating arm to pivotally rotate. As a result, the acting part and the restricting rod pinch to restrict and position the belt. | 08-05-2010 |
20100243838 | Press-fit extendable support rod - A press-fit extendable support rod includes an outer pipe and an inner pipe sheatheable along the outer pipe. An end of a rope is fixed to the inner pipe, and another end of the rope is extendable outward. A press-fit buckle device is sheathed to a joint of the inner and outer pipes. A rotary arm is pivotally coupled to the press-fit buckle device, and an end of the rotary arm has a first operating portion, a second operating portion and a third operating portion. The rotary arm can be pivotally coupled to the press-fit buckle device by one of the operating portions, and another end of the rope is wound onto each operating portion. When the rotary arm is turned, the rope is pulled, turned around, and pressed at each operating portion, and the length of the inner pipe extended out of the outer pipe is adjusted and fixed. | 09-30-2010 |
20110041300 | Hand puller with detachable handle - The present invention disclosed a hand puller with a detachable handle, and the hand puller includes a body, an axle, and a handle. The axle is passed and mounted onto the body, and a sheath opening is formed at an end of the handle for sheathing an edge of the axle, such that the handle can be turned by using the axle as an axial center, and a guide section is defined and formed at an external periphery of the sheath opening, and the body includes at least one stop portion protruded from a position proximate to the guide section of the handle. When the handle is turned by using the axle as the axial center, the guide section and the stop portion are slidably coupled to restrict a radial movement of the handle to prevent the handle from being separated from the axle along the radial direction. | 02-24-2011 |
20110146035 | HAND PULLER WHOSE HANDLE ROLLS IN THE STRAP - A hand puller whose handle can roll in a strap includes a base and a movable arm. The base has a pivotal element. The movable arm is disposed on the outer end of the pivotal element. A ratchet wheel is disposed between the movable arm and both ends of the base, respectively. The movable arm has a second stopping plate and extends with a pulling element. The pulling element has a third sliding groove with a rotating axis. Both ends of the rotating axis are disposed on the two arm boards of the movable arm. A rotating element is provided for the user to rotate, so that the strap is winded on the rotating axis. | 06-23-2011 |
