Radially extending eccentrically movable handle | 2 |
| 20140060256 | WRENCH DEVICE - A wrench device includes a handle having two pivoting holes opened, a clamp member having an enclosing portion and two extension portions, the enclosing portion enclosing a driving member, the two extension portions having a gap communicating with the enclosing portion and two openings, a pivoting rod being inserted into each corresponding opening and pivoting hole, the driving member having an adapting hole and a fastening groove, the enclosing portion engaged with the fastening groove. Under this arrangement, when the handle is rotated in one direction, the enclosing portion of the clamp member tightly clamps the driving member, so that the driving member is rotated by the rotation of the handle; when the handle is rotated in another direction, the driving member is not rotated by the enclosing portion of the handle. | 03-06-2014 |
| 20150101456 | WRENCH DEVICE - A wrench device includes a handle having two pivoting holes opened, a clamp member having an enclosing portion and two extension portions, the enclosing portion enclosing a driving member, the two extension portions having a gap communicating with the enclosing portion and two openings, a pivoting rod being inserted into each corresponding opening and pivoting hole, the driving member having an adapting hole and a fastening groove, the enclosing portion engaged with the fastening groove. Under this arrangement, when the handle is rotated in one direction, the enclosing portion of the clamp member tightly clamps the driving member, so that the driving member is rotated by the rotation of the handle; when the handle is rotated in another direction, the driving member is not rotated by the enclosing portion of the handle. | 04-16-2015 |

| 20080210061 | RATCHET WRENCH THAT IS MOUNTED CLOSELY - A ratchet wrench includes a wrench body, a ratchet wheel, and a drive device. The drive device includes a pawl member, a drive block, and a control button. Thus, the insert of the pawl member is inserted into the slot of the drive block so that the pawl member and the drive block are combined integrally, and the pawl member is limited in the head portion of the wrench body, so that the pawl member and the drive block are retained by the head portion of the wrench body to prevent the drive block and the control button from being detached from the head portion of the wrench body by the push force of the first elastic unit. | 09-04-2008 |
| 20080210062 | Ratcheting manual threader drive device - A ratchet assembly, and particularly, a ratcheting manual threader drive device is described. The device utilizes a unique pawl extension assembly that includes a sleeve, and one or more biasing members that are positioned within a channel extending through the head of the assembly. | 09-04-2008 |
| 20110048177 | Wrench with a sheath - A wrench with a sheath has a wrench body and a sheath. The wrench body has a handle.
