For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of pincers special for sleeve conductive screw, comprise left caliper and the right caliper body of cross-articulation, it is hinged that left caliper and right caliper body pass through hinge symmetry, it more than hinged place is binding clip, it is below clamp handle, described binding clip comprise jaw seat and and be fixed on jaw on jaw seat, described jaw seat is by symmetrically arranged left jaw seat, right jaw seat composition, left jaw seat is a part for right caliper body, right jaw seat is a part for left caliper, described jaw is by symmetrically arranged left jaw, right jaw composition, left jaw seat is fixed on respectively by screw, on right jaw seat, the symmetric position of left jaw and right jaw opposite face arranges semicircle internal thread respectively, in jaw trend closing course, when the center line being arranged on the semicircle internal thread on left jaw and right jaw overlaps, two semicircular internal thread and extended line thereof form unitary circular internal thread.
Further, the symmetric position of left jaw with right jaw opposite face arrange the different semicircle internal thread of two nominal diameters respectively, in jaw trend closing course, when being arranged on the center line coincidence of the semicircle internal thread on left jaw and right jaw, two semicircular internal thread and extended line thereof form unitary circular internal thread.
Further, the center line of the semicircle internal thread described left jaw and right jaw arranged and hinge centerline parallel.
Further, the center line of the semicircle internal thread described left jaw and right jaw arranged and hinge central axis.
Further, in two semicircle internal threads that described left jaw and the right jaw of person are arranged, close to the center line of and the hinge centerline parallel of hinge, another center line and hinge central axis.
Owing to have employed technique scheme, the technological progress that the utility model obtains is:
The utility model by arranging internal thread on jaw, and make pliers when clamping screw, the internal thread on jaw coordinates with the external screw thread of screw rod, enlarge active surface, non-slip between screw rod and jaw, also do not destroy the screw thread of screw rod while realizing clamping, the nut on screw rod for convenience detach.Jaw and jaw seat adopt screw to be connected, and are convenient for changing the jaw of different size specification, to adapt to the screw rod of different size specification.Center line and the hinge centerline parallel of internal thread or vertical, easy to use on jaw.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further details:
The utility model relates to a kind of for clamping screw, thus the special vice of degree of tightness screw rod top nut.As shown in Figure 1, the utility model comprises left caliper 6 and the right caliper body 3 of cross-articulation, it is symmetrical hinged that left caliper 6 and right caliper body 3 pass through hinge 2, hinge 2 is parts of left caliper 6, it more than hinged place is binding clip, it is below clamp handle, described binding clip comprise jaw seat and and be fixed on jaw on jaw seat, described jaw seat is by symmetrically arranged left jaw seat 5, right jaw seat 1 forms, left jaw seat 5 is parts of right caliper body 3, right jaw seat 1 is a part for left caliper 6, described jaw is by symmetrically arranged left jaw 9, right jaw 4 forms, left jaw seat 5 is fixed on respectively by screw 7, on right jaw seat 1, the symmetric position of left jaw 9 and right jaw 4 opposite face arranges semicircle internal thread 8 respectively, in jaw trend closing course, when being arranged on the center line coincidence of the semicircle internal thread 8 on left jaw 9 and right jaw 4, two semicircular internal thread and extended line thereof form unitary circular internal thread.The center line of the semicircle internal thread 8 that described left jaw 9 and right jaw 4 are arranged and hinge 2 centerline parallel.Left jaw and right jaw size, shape and structure are identical, can exchange.Left jaw and right jaw, when producing, only need produce left jaw or right jaw in batches.In use, for the screw rod of different-diameter, different pitch, only left jaw and right jaw need be changed.
More than a specific embodiment of the present utility model, the center line of the semicircle internal thread 8 that described left jaw 9 and right jaw 4 are arranged and hinge 2 centerline parallel.As shown in Figures 2 and 3, be another specific embodiment of the present utility model, the center line of the semicircle internal thread 8 that left jaw 9 described in this embodiment and right jaw 4 are arranged and hinge 2 central axis.Left jaw and right jaw size, shape and structure are identical, can exchange.
In use, what have some specification screw rods is conventional screw rod, for these screw rods, frequent replacing jaw is cumbersome, therefore when designing jaw, the symmetric position of left jaw 9 with right jaw 4 opposite face arrange the different semicircle internal thread 8 of two nominal diameters respectively, in jaw trend closing course, when being arranged on the center line coincidence of the semicircle internal thread 8 on left jaw 9 and right jaw 4, two semicircle internal threads on left jaw 9 form the different unitary circular internal thread of two nominal diameters from two semicircle internal threads on right jaw 4 and extended line thereof, thus realize the screw rod that a pair of tongs can clamp two kinds of specifications.The mode described left jaw 9 and right jaw 4 being arranged two semicircle internal threads 8 both can adopt the mode (as shown in Figure 4) of its center line and hinge 2 centerline parallel, also the mode (as shown in Figure 5) of its center line and hinge 2 central axis can be adopted, a center line and hinge 2 centerline parallel can also be adopted, the mode of another center line and hinge 2 central axis, is positioned at shown in the side (as Fig. 6) close to hinge 2 with that semicircle internal thread position of hinge 2 centerline parallel.
