Abstract: The present invention provides a multi-segment bendable joint, comprising: a jointer, having a rod portion, a first ball head and a second ball head connected at two ends of the rod portion; a first connector, at opposite ends thereof, with a first connecting portion and a first joint slot for receiving the first ball head therein, respectively; and a second connector, at opposite ends thereof, with a second connecting portion and a second joint slot for receiving the second ball head therein, respectively. When one of the first and second connectors is linked to a wrench body and the other acts as a socket, two-segment bending between the socket and the wrench body is allowed, resulting in larger bending angle between the socket and the wrench body compared to conventional products.

The first inverter and the second inverter each includes an inverter that includes a first inverter branch composed of at least one first P-type transistor and at least one first N-type transistor; and a second inverter branch composed of at least one second P-type transistor, at least one second N-type transistor and at least two tuning switches.

Abstract: 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.

Abstract: A wrench includes a function end having an extension portion extending therefrom. Two arms extend from the function end and toward a direction opposite to the extension portion. A space is formed between the two arms and the extension portion. An engaging portion is formed to the distal end of the extension portion for receiving a hand tool. A rotary head is pivotably located in the space of the function end by two bolts respectively extending through the two arms and connected to the rotary head. The rotary head includes an outer part and a control unit which is located in a through hole defined through the outer ring. The control unit includes a control part and a driving part respectively located on two opposite end of the rotary head. The control part is rotated to control the direction that the driving part rotates.

Abstract: An inverter-based comparator, powered between a first supply voltage and a second supply voltage being lower than the first supply voltage, includes a first inverter branch composed of at least one first P-type transistor and at least one first N-type transistor; and a second inverter branch composed of at least one second P-type transistor, at least one second N-type transistor and at least two tuning switches. The first inverter branch and the second inverter branch are configured to compare an input voltage with an internal trigger point, thereby generating a compare voltage at an interconnected node. One of the at least two tuning switches is controlled to isolate the first supply voltage and another is controlled to isolate the second supply voltage to compensate for trigger point shifting.

Abstract: 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.

Abstract: 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.

Abstract: A wrench includes a handle and a working end, two arms extend from the working end to form a room between the two arms. Each arm includes a locking hole. A driving head is pivotably connected between the two arms. Two bolts are respectively and threadedly connected to the locking holes of the two arms, and inserted into the two recesses of the driving head to pivotably position the driving head. A wave washer is mounted to each of the two bolts and sandwiched between the driving head and the arm. The convex portions one side of each wave washer contact the outside of the driving head. The convex portions on other side of each wave washer contact the inside of the arm corresponding thereto. The friction between the driving head and the arms is reduced when the driving head is pivoted relative to the arms.

Abstract: 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.

Abstract: A wrench includes a driving unit located in the head of the wrench. A rod extends through the driving member and includes a stepped recess so as to control a bead in the radial hole of the driving member to secure a socket connected to the driving member. A rotary member is connected to the head and includes a room. A locking member is located in the room and locked to the driving member. A fixing area is formed between the locking member and the driving member so as to fix the locking member and the driving member together. The fixing area ensures that locking member is not separated from the driving member.
