Abstract: A dynamometric tool having a longitudinal axis and capable of providing a tightening torque, includes: a head with a first housing arranged along the longitudinal axis and a second circular housing arranged along a transverse axis perpendicular to the longitudinal axis, the head being adapted for receiving a dowel in the second housing; a shaft to be received in the first housing, the shaft being capable of assuming a working position in which a first end thereof is located in the second housing for engaging with the dowel. In order to make the tool fully removable, the head and the first end of the shaft are arranged and sized so that the head and the shaft can assume a first relative orientation in which the shaft can slide freely relative to the head so that the head can be removed from the shaft, and a second relative orientation in which bearing members are arranged so as to maintain the shaft in the working position.

Abstract: The tool adaptor of the present invention includes a first work piece, a second work piece and a block element. The work pieces are pivoted with each other. The block element is sleeved on the first work piece and slidable between a first position and a second position. As the block element locates at the second position, it engages with the first and second work pieces simultaneously to restrict the sway of the first work piece about the second work piece. The tool adaptor is therefore switchable between a swayable mode and a fixation mode by moving the block element between such positions.

Abstract: A socket connection device including a main body; a slide rod installed in the main body and slidable along the main body, a shallow depression and a deep depression being formed on a front end of the slide rod; and a ball body inlaid in a through hole of the main body. In normal state, a bottom edge of the ball body falls on the shallow depression and a top edge of the ball body protrudes out of the main body. When the slide rod moves to a position where the deep depression is aligned with the through hole, the ball body moves into the deep depression without protruding out of the main body. In the invention, a center of the ball body is positioned outside a bottom wall of the shallow depression. When fitting a socket on the connection device, the socket presses the ball body to drive the slide rod slide, whereby the ball body drops into the deep depression. Therefore, the socket can be directly connected with the device without performing any additional operation.
