The present invention relates to a manual hydraulic multi-functional extra-high-voltage insulating gear gripper pliers stick for live-wire work and the pliers stick and, more specifically, to a manual hydraulic multi-functional extra-high-voltage insulating gear gripper pliers stick for live-wire work and an indirect live-wire construction method using the pliers stick, which: allow components or the like, which are installed on and removed from an electric pole in order to perform electric wire-stringing work or fix electric wires, to be remotely constructed by means of the indirect live-wire work while maintaining a safe distance from live wires when constructing power distribution equipment in an extra-high-voltage live-wire state; ensure safety by eliminating risks due to instability during work, said instability occurring due to the intensity of the labor and the physical limitations of the workers; and bring about improvements in utilization efficiency.

A working head for a hydraulic power tool including a head frame and a first moveable die head configured to move along the working head frame. The first moveable die head configured to receive a first moveable die comprising a first body length. A second die head is adapted to receive a second die comprising a second body length. The first body length of the moveable die is different from the second body length of the stationary die.

The present invention relates to an ergonomic plier tool. More specifically, the invention relates to a piston actuated ergonomic plier tool having a 360-degree rotative and exchangeable head. The tool includes a body, lever, head cylinder, piston and jaw assembly. The disclosed tool allows an operator to work in tight spaces with her hand in one plane, while cutting/manipulating an object in an infinite number of planes different from that of her hand.

The present invention relates to a manual hydraulic multi-functional extra-high-voltage insulating gear gripper pliers stick for live-wire work and the pliers stick and, more specifically, to a manual hydraulic multi-functional extra-high-voltage insulating gear gripper pliers stick for live-wire work and an indirect live-wire construction method using the pliers stick, which: allow components or the like, which are installed on and removed from an electric pole in order to perform electric wire-stringing work or fix electric wires, to be remotely constructed by means of the indirect live-wire work while maintaining a safe distance from live wires when constructing power distribution equipment in an extra-high-voltage live-wire state; ensure safety by eliminating risks due to instability during work, said instability occurring due to the intensity of the labor and the physical limitations of the workers; and bring about improvements in utilization efficiency.

The invention relates to pliers (1). The pliers might be embodied as crimping pliers (2), cutting pliers or pipe crimping pliers. In the pliers (1) pliers jaws (3, 4) are driven by hand levers (8, 9) via a toggle lever drive (13). The toggle lever drive (13) is not formed by toggle lever rods or toggle lever bars. Instead, imaginary toggle levers are formed by a plurality of toggle lever components (35) which are movable along contact contours (30, 37; 33, 38) relative to each other.

A hand-held knockout driver includes a main housing having a handle portion, a motor positioned within the main housing, a pump assembly driven by the motor, and a secondary housing coupled to the main housing and defining a bore therein. The hand-held knockout driver also includes a working piston moveable within the bore from a rest position to an actuated position to define a piston throw distance therebetween. The hand-held knockout driver also includes a draw stud coupled to the working piston, a die coupled to the secondary housing, and a punch coupled to the draw stud opposite the working piston for movement therewith relative to the die. The die has a depth greater than the piston throw distance.

A working head for a hydraulic power tool including a head frame and a first moveable die head configured to move along the working head frame. The first moveable die head configured to receive a first moveable die comprising a first body length. A second die head is adapted to receive a second die comprising a second body length. The first body length of the moveable die is different from the second body length of the stationary die.

An auxiliary tool to be detachably attached to tip portions (36, 46) of a pair of arms (30, 40) which are opened/closed by each rotating relative to a base (24) of an actuation device (e.g., hydraulic actuation device (10)), includes a first auxiliary member (60) to be detachably attached to a first arm (30) of the pair of arms (30, 40), the first auxiliary member (60) having at least one claw portion (62), and a second auxiliary member (70) to be detachably attached to a second arm (40) of the pair of arms (30, 40), the second auxiliary member (70) having at least one claw portion (72). Positions of the claw portion (62) of the first auxiliary member (60) and the claw portion (72) of the second auxiliary member (70) are such positions that the claw portion (62) of the first auxiliary member (60) and the claw portion (72) of the second auxiliary member (70) do not come into contact with each other even when the arms (30, 40) are closed in a state in which the first auxiliary member (60) is attached to the first arm (30) and the second auxiliary member (70) is attached to the second arm (40).
