A manually operable pliers tool has a first pressing jaw with a first handle extending therefrom, a second pressing jaw pivotably mounted on the first pressing jaw about a first pivot axis, and a second handle which can move in a spreadable manner relative to the first handle and which is linked to the second pressing jaw. The second pressing jaw has a u-shaped node element with a base and two limbs extending from the base in the direction of the handles. The base of the node element is mounted on the first pressing jaw via the first pivot axis and a first of the limbs is mounted on the second handle via a second pivot axis. When the pliers mouth formed by the sections of the pressing jaws remote from the handles is opened, the second limb of the node element is pivoted in the direction of an upper outer rim of the first pressing jaw, the outer rim being remote from the second pressing jaw. A stop, which is adjustable between a passive position and at least one active position, is arranged on the first pressing jaw, wherein an opening movement of the second handle can be limited by the second limb of the node element coming to a stop on the stop by setting the stop into the at least one active position.

An embedded element pulling apparatus, the apparatus comprises a pair of linear guides separated by a width, each linear guide having a length and an inner guide surface, the inner guide surface angled to form a closing ramp at the grasping end. A jaw is paired with each linear guide; each jaw is engaged to follow along the inner guide surface. Each jaw may have an interchangeable grasping tooth. A lock assembly is integrated to lock and unlock the jaws. A carriage cooperatively couples the jaws and the lock assembly. A positioning actuator engages with the carriage to position the jaws along the length of the linear guides and a drive actuator engages with the carriage to close the jaws, pull the embedded element, and open the jaws. A motive device may drive the positioning actuator and drive actuator.

A hand tool includes a handle section, a working end operably coupled to the handle section, and a jaw assembly disposed at the working end. The jaw assembly includes a movable jaw and a fixed jaw. A span defined between the movable jaw and the fixed jaw is adjustable. Each of the movable jaw and the fixed jaw includes an array of teeth defined by ridges that extend substantially parallel to each other. The array of teeth on each of the fixed jaw and the movable jaw includes a first set of teeth having a first width and a first depth, and a second set of teeth having a second width and a second depth. The first depth is less than the second depth and the first width is less than the second width.

A release tool for cable connector, Having opposed levers with a spreader tip and a locator tip arranged thereon, and adapted to provide an instant force to a cable connector, such that a degree of retainment is reached which effects and adjustment of the fit value of the connector with respect to a grip object to a release value, at which point a grip object within the connector is released.

A clipless bicycle pedal auxiliary tool includes two cramp bodies, each cramp body includes a pivot part, a holding section and a clamping section, the two pivot parts are pivoted with each other, and the holding sections and the clamping sections are disposed on two sides of the pivot parts, respectively. Each clamping section includes a clamping pin and a pushing pin protruded thereon. The two holding sections can be operated to pivotally swing the two clamping section relative to each other, and make the two clamping pins and the two pushing pins move close to and away from each other, so that the two clamping pins can clamp the two inner sides of the clamping fastener of the clipless bicycle pedal, and the two pushing pins push the two outer sides of the clamping fastener to form a force pivot.
