The specific embodiment

The utility model is relevant for a kind of C type retaining ring tongs structure, it is the C type retaining ring tongs of a tool fast replacing work rod member specification, be beneficial to the engineering staff and must regard industry demand replacement work rod member up to specification rapidly as, to promote operating efficiency, refer to shown in Fig. 1 to Fig. 7, the utility model " C type retaining ring tongs structure " includes a tonger body 1, two backstays 2 and two work rod members 3;

This tonger body 1 is pivoted and is formed by two clamp handles 11 intersections, this tonger body 1 is pivoted by two clamp handles 11, and to form a side be press-side A in position, the opposing party is working end B, this two clamp handle 11 respectively is formed with a joining hole 12 of planting for work rod member 3 in working end B, and this two clamp handle 11 in working end B mono-side respectively be formed with one with the axis hole 13 of joining hole 12 vertical conductings;

The section that this work rod member 3 is inserted in joining hole 12 1 ends is formed with a neck inside contracted 31, and this neck 31 is when work rod member 3 is inserted in joining hole 12, just corresponding to joining hole 12 conducting axis hole 13 positions;

This backstay 2 is formed with an axostylus axostyle 21 that is hubbed at axis hole 13, the local external diameter of this axostylus axostyle 21 1 is arc, and rotarily driven by axostylus axostyle 21 can to stretch into joining hole 12 and compel to be butted on the positioning section 211 of neck 31, and these axostylus axostyle 21 another local external diameters are plane, and rotarily driven by axostylus axostyle 21 break away from joining hole 12 and remove the releasing section 212 of neck 31 restrictions;

So, these axostylus axostyle 21 positioning sections 211 can provide work rod member 3 the stable clamp handle 11 (as shown in Figures 2 to 4) that is assembled in, when wish is replaced the work rod member 3 of different size, only need switching two backstays 2, make releasing section 212 corresponding to neck 31, to remove its restricted kenel, can carry out the replacement (as shown in Figures 5 and 6) of work rod member 3.

Furthermore, this clamp handle 11 has one for after backstay 2 foldings corresponding to the position depression of backstay 2, presents the depression section 14 that fits into the one kenel with clamp handle 11; So, when user's normal operation, its backstay 2 is integrated in clamp handle 11, to avoid backstay 2, interferes construction.

Furthermore, when this backstay 2 is folded in depression section 14, this positioning section 211 compels to be butted on the position of neck 31, and backstay 2 lifts off when depression section 14, and this releasing section 212 is corresponding to the position of neck 31.

Furthermore, these backstay 2 surfaces are formed with on-slip burr 22; Because its backstay 2 of the utility model is designed to be integrated in clamp handle 11 kenels after folding, the application of force that by this on-slip burr 22, can provide operator one to pull, the operation while replacing with convenient the utility model work rod member 3.

Furthermore, this work rod member 3, except neck 31 positions, is a polygonal body of rod, the polygonal hole that this joining hole 12 is a corresponding working beam part 3; So, in the time of making work rod member 3 be assembled in clamp handle 11, produce improperly and rotate.

From aforementioned utility model content, the utility model be take and locked that to compel be fixing mode by screw with respect to existing, without separately replacing so that driver tool is auxiliary, advantage with replacement, and the utility model only needs to pull backstay and obtains the fixing or work of release rod member, separately has advantages of the fast replacing specification; The person is only in order to explain preferred embodiment of the present utility model from the above mentioned; not attempt tool the utility model is done to any pro forma restriction; be with; all have be relevant any modification of the present utility model or change person under identical utility model spirit; for other aspects that can implement according to this and there is same effect person, all must be included in the category of the utility model intention protection.

In sum, " C type retaining ring tongs structure " of the present utility model, on structural design and use practicality, really meet practicality, and disclosed structure creation, also to there is unprecedented innovative structure, so it has " novelty " should be without doubt, the utility model can have more than existing structure the enhancement of effect again, therefore also has " creativeness ", and it meets the regulation of the relevant utility application of Patent Law fully, therefore, whence proposes patent application to an ancient unit of weight office in accordance with the law, earnestly asks an ancient unit of weight office and can vouchsafe early this case patent right, to feeling moral just.
