Type of joining pliers

An improved type of joining pliers, particularly one that presses and joins an object (coating terminal) to a conductive wire and can make correction without being deviated or displaced during a compressing and joining process, comprising a left handle, a right handle that is pivoted to the left handle so the two handles can be opened or folded to each other, an opening mold that is movably pivoted to the left handle, and a slide block that is movably pivoted to the right handle and can be embedded in the opening mold; by the mobility of the opening mold and the slide block that are movably pivoted to each other, the assembling position of the mobile opening mold and the slide block can be automatically corrected when the left and right handles are folded.

What is claimed is:

1. An improved set of joining pliers comprising:

a first handle;

a second handle pivotally coupled to the first handle, the first and second handles being pivotally displaceable one relative to the other between opened and closed positions;

an opening mold including a mold unit and a mold body, the mold unit being movably pivoted to the first handle, the mold body being inserted in the mold unit; and,

a slide block movably pivoted to the second handle, said slide block being embedded in the opening mold for slidable displacement therein responsive to the relative pivotal displacement of the first and second handles between the opened and closed positions;

the opening mold and the slide block being thereby self-adjusted in relative linear alignment during the pivotal displacement of the first and second handles, the mold unit being accommodated in the mold body, the mold body and the slide block being replaceable when other types of objects are being compressed and pivoted;

wherein the mold unit and the mold body are engaged by an assembly structure therebetween, the assembly structure including first and second snap fasteners installed between the mold body and the mold unit, said first and second snap fasteners being fastened to each other and being separable from each other by an outside force.

2. An improved set of joining pliers comprising:

a first handle;

a second handle pivotally coupled to the first handle, the first and second handles being pivotally displaceable one relative to the other between opened and closed positions;

an opening mold including a mold unit and a mold body, the mold unit being coupled in pivotably displaceable manner to the first handle, the mold body being inserted in the mold unit; and,

a slide block coupled in pivotally displaceable manner to the second handle, said slide block being embedded in the opening mold for slidable displacement therein responsive to the relative pivotal displacement of the first and second handles between the opened and closed positions;

the opening mold and the slide block being thereby self-adjusted in relative linear alignment during the pivotal displacement of the first and second handles, the mold body and the slide block being replaceable when other types of objects are being compressed and pivoted;

wherein the mold unit and the mold body are engaged by an assembly structure therebetween, the assembly structure having a second snap fastener on an inside wall of the mold unit, and a first snap fastener on a matching outside wall of the mold body to match the second snap fastener, the first and second fasteners being separable from each other by an outside force.

3. The improved joining pliers of claim 2, wherein the first snap fastener is shaped like a post and vertically pivoted to the mold body, on a side near a top of the first snap fastener being a depressed groove that is engaged for fastening purpose.

4. The improved joining pliers of claim 2, wherein the second snap fastener is a flange protruding from an inside wall of the mold unit.
