A pair of pliers has a first and a second plier leg, which are mounted so as to be rotatable relative to one another in a joint region and which form gripping regions on one side of the joint region and a plier jaw on the other side. A locking part fixes position of the pliers. The locking part is rotatably mounted on the first plier leg at a transition between the gripping region and the joint region of the plier leg, and, in the fixed position, fixes the pliers by contact with the joint region of the second plier leg. The locking part, in the fixed position and under load, is in supporting contact both with the joint region of the second plier leg and with the gripping region of the first plier leg in a plane perpendicular to the axis of rotation of the plier legs.

A plug for retaining a filter screen in a fluid port of a servovalve, comprises an annular body, the annular body comprising: opposed first and second axial end surfaces, a radially inner surface extending between the first and second axial end surfaces, a radially outer surface extending between the first and second axial end surfaces and at least one recess formed in the radially inner surface for receiving a tool for removing the plug from the port. A tool for removing the plug comprises a pair of handles pivotally mounted to one another about a pivot, each handle having a plug gripping portion extending therefrom beyond the pivot, each plug gripping portion comprising an outwardly projecting tooth for engaging in the recess of the plug when the plug gripping portions are moved apart by operation of the handles.

Disclosed are a ceramic tile leveling bracket, pushing and clamping pliers and a ceramic tile leveling and laying system. The ceramic tile leveling and laying system comprises: a ceramic tile leveling bracket (1), an insertion block (2) and pushing and clamping pliers (3), wherein the ceramic tile leveling bracket (1) is provided at the junction between two adjacent ceramic tiles (4), one end of the insertion block (2) is inserted into an insertion block through hole (16) of the ceramic tile leveling bracket (1), and the pushing and clamping pliers (3) push and clamp the insertion block (2) into the insertion block through hole (16), so that an insertion block bottom surface (21) is tangent to upper surfaces of the two ceramic tiles (4). The ceramic tile leveling and laying system is easy to operate, and helps to improve the laying efficiency and laying quality.

The pipe pliers includes a first clamping body, a driving handle, and a clamping element. The first clamping body includes a body portion. The body portion includes two side plates and is formed with two guiding toothed grooves. A receiving groove is defined between the two side plates. Each side plate is formed with a sliding groove facing the other side plate. The driving handle is slidably arranged at the two guiding toothed grooves and is pivotable with respect to the first clamping body. The driving handle has a protrusion. The clamping element is slidably arranged at the two sliding grooves. The clamping element has a recess. The protrusion is rotatably inserted into the recess. When clamping a workpiece, the clamping element slides linearly.

The ceramic tile leveling and laying system comprises: a ceramic tile leveling bracket, an insertion block, and pushing and clamping pliers, wherein the ceramic tile leveling bracket is disposed at a junction of at least two adjacent ceramic tiles, one end of the insertion block is inserted into an insertion block receiving portion of the ceramic tile leveling bracket, and the pushing and clamping pliers push and clamp the insertion block into a ceramic tile leveling bracket such that a bottom face of the insertion block is tangent to upper surfaces of the ceramic tiles. The ceramic tile leveling and laying system is easy to operate, and improves the laying efficiency and laying quality.

The present invention relates to a hand tool. More specifically, a rapid adjust multigrip tool having a first arm, second arm, linking mechanism and locking mechanism. The first arm is connected to the second arm via a primary pivot. The linking mechanism biases the arms away from one another. The locking mechanism allows an operator to selectively secure the first and second arms together.

The wrench includes a first member having a first jaw. The first jaw has at least one first nut member contacting edge. The wrench also has a second member having a second jaw. The second jaw has at least one second nut member contacting edge. The wrench further has a pivot axis at which the first and second members are pivotably coupled to each other, thereby allowing the first and second jaws to be movable between an open position and a closed position, and at least one opening defined by the at least one first nut member contacting edge and the at least one second nut member contacting edge, when the first and second jaws are positioned in the closed positions.
