Structure pliers for inner and outer diameter C-shaped snap

An improved structure pliers for inner and outer diameter C-shaped snap rings comprised of a two-part symmetrically paired left and right-handled pliers body that is situated together at a predetermined point between its two inner sides and, furthermore, in an upper and lower overlaid and pivotably linked assembly positioning;

• two implement ends capable of being articulated apart and together by pivoting at the front portion and two hand grips for manual operation are disposed at the rear portion;
• and an elastic component mounted between the said two hand grips near their pivotable linkage area to provide a rebound force when the said two hand grips are pivoted by squeezing, the innovative features of which include:
• the said two implement ends have a first mounting hole and a second mounting hole respectively formed in them;
• the said two hand grips have a third mounting hole and a fourth mounting hole respectively formed in them near their pivotable linkage area;
• each said mounting hole is circumferentially situated an equal radius in length way from the center point of the said overlaid and pivotably linked assembly positioning;
• the said two-part pliers body has a jaw at each of its two upper and lower two sides that are overlaid and in a pivotably linked assembly positioning and, furthermore, which respectively share the same pivotal axis;
• the said two jaws have a through-hole disposed that corresponds to the site of the said first mounting hole and the said second mounting hole, respectively, and attached to its front end are tip members capable of being turned up and down for angular adjustment to facilitate C-type snap ring distension or constriction;
• positioned at each of the upper and lower two sides of the said two jaws in a movable arrangement and, furthermore, respectively along the same axis is a direction control component;
• each said direction control component has perpendicularly disposed at their two lengthwise ends a long post and a short post that are situated relative to the said first mounting hole and the said third mounting hole as well as the said second mounting hole and the said fourth mounting hole, respectively;
• as such, the said long posts can be optionally inserted beyond the said jaw through-holes and coupled into the said first mounting hole (or the said second mounting hole) or the said short posts can be optionally inserted into the said jaw through-holes such that the said long posts are coupled into the said third mounting hole (or the said fourth mounting hole), enabling the said two implement ends at the two sides of the said jaws to either distend or constrict in operation and thereby provide inner and outer diameter C-shaped snap ring installation and removal in various spatial operating environments.
