A torque transfer control mechanism that suppresses output-side displacement, and including a rotation control unit that maintains a locked state when an input torque rotating a transfer mechanism is not applied, and releases the locked state when the transfer mechanism rotates. The rotation control unit includes an internal gear and lock plates that include outer teeth that can engage with inner teeth of the internal gear. When an input torque is not applied, the inner teeth of the internal gear engage with the outer teeth of the lock plates, and when the transfer mechanism is rotated, engagement between the inner teeth and the outer teeth is released. Thus, even when torque is applied from the output unit side, engagement between the inner teeth and the outer teeth is not released by the torque.

A wrench rotational axis re-positioning apparatus includes a housing, an interior cavity defined in the housing, input and output gear assemblies mounted to the housing and disposed in the interior cavity in a meshing contact with one another and rotatable about respective first and second axes arranged in a right angle configuration with one another, the input and output gear assemblies having respective input and output fittings for connection to respective drive and driven devices, and a ratcheting mechanism mounted to the housing and extending from exterior thereof into the interior cavity such that the ratcheting mechanism is presettable in either one of first and second orientations relative to the output gear assembly to enable the latter to correspondingly rotate in one or the other opposite direction about the second axis in response to the input gear assembly being rotated in either opposite direction about the first axis.

A handle of a load binder. The handle includes a handle gear housing having a front end opposite a rear end. An outer handle gear is rotatably coupled within the handle gear housing. At least one drill connector 16 is extending laterally from the handle gear housing and is operable to rotate the outer handle gear when driven. A handle grip protrudes from the rear end of the handle gear housing. A binder gear housing protrudes from the front end of the handle gear housing. The binder gear housing includes an outer wall and a sidewall extending inward from the outer wall. The sidewall has a U-shaped cutout. The U-shaped cutout releasably receives a binder stem of the load binder and positions the outer handle gear to interlock with a binder gear of the load binder.

A hand tool assembly includes a body having a ratchet portion, a room and a window. A driving unit is rotatably received in the ratchet portion and the room of the body. The driving unit includes a driving head, a pawl, a spring and a rotary member. The rotary member is rotated via the window to control the operational directions of the driving unit. A seat is connected to the body, and the driving unit is connected between the body and the seat. The seat includes an insertion portion formed on one end thereof, and which is engaged with the room. The seat has an engaging portion formed on the other end thereof. The seat is replaceable to make the hand tool assembly have more functions.

A ratcheting belt system with opposed rollers and quick release capability provides two opposed rollers which frictionally allow a tightening belt of a safety harness, cargo securement system, between themselves compressively, via a manually operated ratcheting handle such that the excess length of belt distal to the active portion used for securement is passed through the system substantially parallel to the active portion of belt, and need not be contained on a spool. A ratchet mechanism prevents back-out of the belt through the buckle, a manually operated lever provides for opening of the rollers away from each other and easy, quick exit of the driver, passenger, or cargo from securement.

A rotary high lifter and controlled descender has a main housing enclosing a ratchet spool, controlled descender, and locking pawl. An adjustable crank turns the ratchet spool and takes up rope which raises an attached feeder, nestbox, etc. The locking pawl assures that as the rope is wound, the lifter/descender automatically locks in place so that an inadvertent crank release of the crank does not cause the feeder to fall. The rope exits the main housing via an inlet nipple which protects the housing from the elements, insects, etc. To lower the feeder, actuate a cam lock to release the locking pawl, and turn the crank in the opposite direction. Releasing the cam lock can actuate a controlled descender portion of the invention. These components apply a brake-pad-like action against the ratchet spool (can also use a tension knob) to control the speed of rotation and descent.

A step-by-step mechanism with a housing (2) in which an outer ring (3) and an output element (4) are disposed, the outer ring (3) including double-clamp ramps (6) and the output element (4) including an inner clamping track (7), and, in an annular space (8) formed between the outer ring (3) and the output element (4), clamping bodies (9) being disposed which cooperate with the double-clamp ramps (6), the clamping bodies (8) being spring-loaded. Provided in the housing (2) is a housing-fixed sleeve (10) and spring elements (13) that spring-load the clamping bodies (9) are supported on the sleeve (10).

A quickly released and fastened adjustment mechanism including a gasket, a first ratchet, a second ratchet, a T-shaped sleeve and a fastener is installed between a sliding member and a fixing member. The first and second ratchets are arranged with annular teeth respectively while the two annular teeth are engaged. The T-shaped sleeve is mounted in the first and second ratchets and against the gasket. The fastener is passed through the T-shaped sleeve, the gasket and the sliding member to be secured on the fixing member. Thus the two corresponding annular teeth are engaged firmly. The height difference between low-level and high-level engagement of the two annular teeth is H.sub.f. The sleeved height of the T-shaped sleeve is D.sub.1. The total height of the first and second ratchets in the low-level engagement is D.sub.2. D.sub.1>D.sub.2. D.sub.1D.sub.2=G>0 and H.sub.f>G>0.
