A reversible ratchet tool includes a cage-type reversing mechanism including a cage member for shifting rollers from their first positions to their second positions. The structure and configuration of the cage member is improved with resilient members for preventing the rollers being stuck unintentionally when the rollers are positioned either in the corresponding first positions or the corresponding second positions, while being capable of maintaining and restricting the rollers upright in place when the rollers are shifted from the corresponding first positions to the corresponding second positions.

Reversible ratchet tool

A wrench has a head with an inside cylindrical wall surrounding a body with ramps. Cylindrical rollers located between the ramps and the cylindrical wall of the head are moved into wedging positions relative to the ramps and the inside cylindrical wall with permanent magnets located in a cage assembly anchored on the body.

Wrench

A wrench has a roller motion transmission mechanism that changes reciprocating motion of a driving member to unidirectional rotational motion of a driven member. The wrench has a head with a cylindrical inside wall surrounding a body with a plurality of ramps inclined toward the cylindrical inside wall. A wedging member comprising a cylindrical roller engages each ramp and the cylindrical inside wall of the head. A cage anchored to the body retains the wedging members in contiguous locations relative to the ramps and the cylindrical inside wall of the head. Retainers connected to the cage bias all of the wedging members into engagement with the ramps and the cylindrical inside wall of the head.

The wrench as a head with an inside cylindrical wall surrounding a body with a plurality of protrusions. Each protrusion has a ramp inclined toward the cylindrical wall. A wedging member comprising a cylindrical roller engages each ramp and inside cylindrical wall of the head. A cage anchored to the protrusions retains the wedging members in engagement with the ramps and the inside cylindrical wall of the head.
