Abstract:
A dust proof structure for a stress-sensible screw is provided. The dust proof structure includes a sensing screw, a head, a dust proof boot and a displayer. The sensing screw includes a base and at least one exposed lead, and the exposed lead is located in the base and transmits a stress signal. The head includes a lead base, the head is fitted with the base, and the exposed lead is detachably connected to the lead base. The dust proof boot is disposed on the head, and sleeves a connecting portion between the lead base and the exposed lead. The displayer is electrically connected w the had for displaying the stress signal.
Abstract:
A spring compensation structure for a torque wrench includes a body, a compensation component and an engaging head. The body has a first connecting portion, The compensation component is installed on the body and has a compensation distance, wherein one end of the compensation component is abutted on the first connecting portion of the body. The engaging head has a second connecting portion; the second connecting portion is detachably disposed on the body and is abutted on the other end of the compensation component, wherein a distance between the second connecting portion and the first connecting portion is equal to the compensation distance.
Abstract:
A threaded member has an axial direction. A thread is formed on the threaded member in the axial direction. At least one receiving recess is formed on a circumferential surface of the thread of the threaded member. At least one sensor member is disposed in the receiving recess for detecting tension applied to the threaded member in the axial direction. When a tightened article is tightened by the threaded member, an extension force/tension is applied to the threaded member in the axial direction. The sensor member is positioned in adjacency to the thread of the threaded member so that the sensor member can precisely detect the extension extent of the threaded member for precisely obtaining the tightening force applied to the threaded member.

Abstract:
A wrench including a handle, an open drive portion, and a closed drive portion is provided. The open drive portion and the closed drive portion are located at two ends of the handle, respectively. The handle includes a first side, a second side, and two recessed structures. The second side is opposite to the first side. The recessed structures are formed on the first side and the second side, respectively. The recessed structures are near the ends of the handle, respectively. Both the open drive portion and the closed drive portion have an abutting plane. Each abutting plane forms an angle with an extending axis of the handle.
Abstract:
A socket-driven lighting connector is configured to connect with a socket and includes a connector main body, a light bulb, a switch, and a positioning ball. The connector main body includes an enclosing wall and a radial through hole. The enclosing wall surrounds and forms a through space. The radial through hole penetrates the enclosing wall and is in communication with the through space. The light bulb is disposed in the through space. The switch is provided in the through space and is electrically connected to the light bulb. The positioning ball is movably provided in the radial through hole. The switch and the positioning ball are so structured that by mounting the socket on the connector main body, the light bulb can be turned on to enhance the efficiency with which the socket can be operated in the dark.
Abstract:
The invention is a hand tool for enhancing strength of a working head, which comprises: a main body with two parallel ears spaced apart at a front end; a working head with a pivotal portion pivotally connected between the ears of the main body; a column with one end connected to a periphery of the pivotal portion; and a strengthening portion extending from the periphery of the pivotal portion toward the column, and disposing at a junction of the pivotal portion and the column. An outer diameter of the strengthening portion is greater than an outer diameter of the column, the strengthening portion is capable of enhancing a strength of the column, relatively improving a torsion applied by the column to a workpiece, and enhancing durability and strength of the column.
