摘要： A socket includes a first section and a second section. The first section is to be connected with a tool. The second section includes an outer face, and a mounting hole is axially defined through the second section and communicates through the first section. The mounting hole includes multiple recesses and multiple sides defined in the inner periphery thereof. The multiple recesses and the multiple sides are located alternatively with each other. Each recess includes a rounded corner formed radially in the inner portion thereof. A triangular groove is formed axially and centrally in each side. The angle between two insides of each groove is smaller than 90 degrees. A rusted or damaged bolt head is engaged with either the rounded corners or the grooves so as to be effectively rotated.

摘要： A hand tool with angle adjusting mechanism includes a handle, a driving head, an engaging assembly and a button. The handle has a receiving groove, a transverse hole and a longitudinal hole. The driving head has a connecting portion disposed in the receiving groove. The engaging assembly has an engaging member and a spring. The engaging member has an engaging tooth at a top thereof for engagement with the driving head, and has an arc-shape pushing groove in a lateral side with an arc-shape wall inside thereof. The button is movably disposed in the transverse hole of the handle, and has an abutting portion slidably inserted in the arc-shape pushing groove, the abutting portion of the button has an arc-shape plane abutting against the arc-shape wall such that horizontal movement of the button drives the engaging member to move longitudinally along the longitudinal hole of the handle.

摘要： A ratchet ring includes six first driving portions formed to the inner periphery of the ratchet ring. Each first driving portion includes a first driving face and a toothed face. A second driving portion is formed in each of the six first driving portions and includes two second driving faces which respectively extend from the first driving face and the toothed face. A first angle is formed between the two second driving faces. A third driving portion is formed in each of the six first driving portions and includes a recess located between the two second driving faces. A second angle is formed between two sides of the recess. A step is formed between the two second driving faces and the third driving portion. When a corner of an object is engaged between the two second driving faces, the step avoids the object from dropping from the ratchet ring.

摘要： A telescopic wrench includes an outer tube, an outer sleeve, and an inner rod. The first hole of the outer sleeve ring is fitted onto the outer tube, and the second hole of the outer sleeve provides peripheral contact with the rod section of the inner rod. The outer sleeve forms an external auxiliary fitting structure with the inner rod and outer tube. The telescopic wrench provides an improvement over known structures that are prone to loosening and noise during use. The telescopic wrench enhances the structural strength when subjected to operating forces.
