Abstract
The invention discloses double-purpose tongs for assembling and disassembling a chain joint. A tong handle is operated to simultaneously open or close two first clamping blocks, and a tool can be connected with a chain sheet in a detachable or combined automatic clamping mode so as to realize the double-purpose effect on assembly and disassembly; meanwhile, each clamping block is provided with a curved propping edge, and the curved propping edge has circular arc shape or toothed texture or the both; and the curved propping edges are encircled and propped against the periphery of the chain tip of the chain sheet, so that the double-purpose tongs have the effect on stable operation.
Description
Technical field
The present invention relates to a kind of chain joint group and unload gripping tongs, specifically be meant a kind of instrument that is applicable to the self-clamping type connection chain sheet of dismounting bicycle chain.
Background technology
Existing bicycle chain connection chain sheet mainly has been many outer chain sheet and at each many ring fixing ditch of the chain tip one end or two ends, and this outer chain sheet then correspondence is provided with the C type and buckles edge, and then outer chain sheet is fastened on this fixing ditch, thereby avoids the chain tip to deviate from.
As for this class connection chain sheet of dismounting, just must use the instrument of specialization, fixedly connected chain sheet struts outer chain sheet more earlier, extrudes the chain tip and finishes dismounting with push rod at last.So, range the chain cutter in the patent IC B21L 21/00 at present, all belong to suitable this quasi-tradition chain.
But, self-clamping type connection chain sheet, extremely shown in Figure 3 as No. 5291730 Fig. 1 of United States Patent (USP) or No. 5362282 Fig. 1, the dismounting of this class connection chain sheet does not but have specific purpose tool.Current practice is to take general hand-held tool to tear open, for example uses nipper plier that the chain tip is supported into taking off the hole by draw-in groove.When assembling chain sheet, equally also to use hand-held tool that the chain tip is supported into draw-in groove by taking off the hole.Yet the chain tip of self-clamping type connection chain sheet is an arc surface, has only a bit with the pincers end of nipper plier to contact, and is very easy to skid, and is very inconvenient.
In addition, the dismounting of self-clamping type connection chain sheet and the direction of operating of combination, just opposite in fact, that is to say that dismounting the time is by the cramping chain tip in the lateral, and be outwards to strut the chain tip during combination by the inboard.If only use one common nonelastic general with nipper plier (normality closure/left caliper with right caliper body intersect pivot joint), it is gruelling to strut the operation meeting.And if use normality to open the nipper plier of (left caliper parallel and in the stage casing pivot joint) with right caliper body, it is more laborsaving to strut the operation meeting.But, like this to use two nipper pliers to dismantle and work in combination.
So, not special-purpose at present at the dual tool of tearing open on the group self-clamping type connection chain sheet.
Summary of the invention
The object of the present invention is to provide a kind of chain joint group to unload gripping tongs, can skid and can't the realization group unload dual-purpose problem to solve in the prior art instrument.
