| 20100101376 | Ratchet Open End Wrench - A ratchet open end wrench includes a wrench body provided with an operation head, a ratchet unit mounted on the operation head, and at least one drive unit mounted on the wrench body and engaged with the ratchet unit. The ratchet unit includes a ratchet member provided with a plurality of oneway ratchet teeth. The drive unit includes a pawl member provided with a plurality of oneway driving teeth engaged with the oneway ratchet teeth. Thus, the ratchet member is driven by the pawl member to rotate a workpiece, so that the reaction force applied by the workpiece onto the operation head is shared by and distributed on the drive unit and the wrench body to prevent the force from being concentrated on the operation head. | 04-29-2010 |
| 20100101382 | Hand Tool that can Replace Tips Easily and Quickly - A hand tool includes handle, a connector mounted on the handle and having an inner wall provided with a mounting hole and a peripheral wall provided with a plurality of positioning holes, a drive member mounted on the connector and having a first end provided with a fixing portion which is detachably mounted in the mounting hole of the connector and has a peripheral wall provided with a fixing groove, a plurality of locking balls movably mounted in the positioning holes of the connector and movable into the fixing groove of the drive member to lock the drive member onto the connector, and a control sleeve movably mounted on the connector and movable to press or release the locking balls. Thus, the drive member can be detached from the connector to facilitate a user replace the drive member. | 04-29-2010 |
| 20100122608 | Open-Ended Ratchet Wrench - An open-ended ratchet wrench includes a handle provided with an open driving head, an open ratchet wheel mounted in the driving head of the handle and having an outer wall provided with a plurality of oneway ratchet teeth, and a pawl member movably mounted in the driving head of the handle and having a first side provided with a plurality of oneway locking teeth detachably meshing with the ratchet teeth of the ratchet wheel. Thus, the ratchet wheel has a side provided with an opening to make the ratchet wheel flexible so that the ratchet wheel is mounted on and detached from the workpiece easily and quickly, thereby facilitating a user operating the ratchet wrench to rotate the workpiece. | 05-20-2010 |
| 20100122610 | Adjustable Wrench That Clamp a Workpiece Exactly and Tightly - A wrench includes a handle, and a driving unit pivotally mounted on the handle. The handle has an end portion provided with a support surface. The driving unit includes a first jaw having a first end pivotally mounted on the end portion of the handle, and a second jaw having a first end pivotally connected with a second end of the first jaw and a second end that is movable to abut the support surface of the handle and the first end of the first jaw. Thus, the second end of the second jaw abuts the support surface of the handle tightly and closely so that the force applied by a user is transmitted to the wrench directly so as to drive the wrench to operate the workpiece in an energy-saving manner. | 05-20-2010 |
