Three-claw-centering wire-pressing pliers

Abstract

The invention discloses a pair of three-claw-centering wire-pressing pliers. The three-claw-centering wire-pressing pliers comprise a plier opening, an accurate adjusting mechanism and handles; the three-claw-centering wire-pressing pliers are characterized in that the plier opening comprises an outer sleeve, an inner sleeve and crimping heads, wherein the outer sleeve is a fixed sleeve connected with an upper handle; the inner sleeve is a movable sleeve which is positioned in the center of the outer sleeve and connected with a lower handle; inner arcs which are deviated from the center are formed in positions of three equally-divided parts of 120 degrees on the inner side of the outer sleeve; three movement inner cavities are formed between the three inner arcs and the outer side wall of the inner sleeve; three column holes and three side holes are formed in the inner sleeve in a crossing manner; crimping heads sleeved with compressed springs are arranged in the three side holes respectively; the tail parts of the crimping heads prop against the corresponding inner arcs of the movement inner cavities; therefore, when the lower handle is kneaded upwardly to drive the inner sleeve to rotate, the tail parts of the crimping heads can be driven to move, in a manner of being tightly clung to the inner arcs; and meanwhile, the heads of the crimping heads can realize the wire-pressing function through extension in a central wire-pressing hole. By adoption of the three-claw-centering wire-pressing pliers, three-claw centering and guarantee of non-eccentricity in the wire-pressing process can be accurately accomplished under the conditions of lower cost and low material consumption.

Description

technical field [0001] The invention relates to a device for crimping a wire and an interface, in particular to a three-jaw centering wire crimping pliers. Background technique [0002] Wire crimping pliers is a hardware tool that connects wires by cold pressing, and is a necessary tool for line maintenance in the power industry. However, the old-fashioned crimping pliers that have been used in my country for a long time are very inconvenient to use, and the crimping quality is poor. Imported crimping pliers are very expensive. Therefore, easy to use and good quality crimping pliers have become the long-cherished wish of the majority of electricians. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention proposes a new material-saving three-jaw centering wire crimping pliers, in order to accurately complete the three-jaw centering pliers at a lower cost and a small amount of material. Center and ensure no eccentr...
