The specific embodiment
As Fig. 1, shown in 2, technical scheme of the present invention is: a kind of Power Tong binding clip clamping body that does not damage body, by opening gear 6, opening gear cap 4, jaw plate frame 3, introversion ramp 5, jaw 11, jaw roller 8, Roller Shaft 9, introversion dental lamina 1, dental lamina rotating shaft 7 is formed, there is axial dovetail groove opening gear 6 inboards, introversion ramp 5 is inlayed wherein, jaw plate frame 3 is in opening gear 6 inside, there is the square hole that jaw 11 is installed its opening symmetry both sides, square hole has gathering sill 2 up and down on the y reference axis, jaw 11 is falcate, on its symmetrical center line, there is the up and down outstanding guide rail 10 can be along jaw plate frame gathering sill 2 radial centripetal slippages about in the of 3, on its symmetrical center line, axis hole is arranged, Roller Shaft 9 is installed wherein, roller 8 is between two axis holes and can rotates around Roller Shaft 9, the two ends of Roller Shaft 9 are embedded in jaw plate frame energy slippage in the gathering sill 2 about in the of 3, there is axis hole jaw 11 symmetrical center line both sides, on introversion dental lamina 1 symmetrical center line axis hole is arranged, axis hole is separately passed through in dental lamina rotating shaft 7, and two introversion dental laminas 1 are linked on jaw 11.
As shown in Figure 3, jaw plate frame 3 is temporarily braked, opening gear 6 clockwise rotates, roller 8 relative introversion ramp 5 climbings, jaw 11 moves to the centre of gyration, four introversion dental laminas 1 hug body 14, button in the enforcement, introversion dental lamina 1 has inner arc surface and stuck pipe body 14 to match, and is intensively distributed with axial bald tooth on its inner arc surface, owing to be bald, densely distributed, it is big to contain area, prick not inlet pipe body, thereby damage is not caused on body 14 surfaces, bald tooth can increase the coefficient of friction to the body surface, and the vertical and lateral trench on introversion dental lamina 1 inner arc surface can deposit the greasy filth foreign material, containing body surface circumference can be near 340 ° in rotating around dental lamina rotating shaft 7 for four introversion dental laminas 1, under the situation that strengthens clamping force (promptly suitably reduce cut footpath than), body 14 still can keep original cylindricity, is not pressed from both sides not flat.When opening gear 6 rotates counterclockwise shackle, move as the same.
As shown in Figure 4, have in the jaw plate frame 3 and hold the space (numbering 13) that dental lamina 1 rotates referring to Fig. 3, when the opening gear reverses to breach, under the counter-rotating action of centrifugal force, dental lamina 1 is with jaw 11 recession, dental lamina 1 near opening one side can rotate around dental lamina rotating shaft 7, abdicates the space and makes 14 turnover of stuck pipe body without hindrance.
As shown in Figure 5, when needing to change dental lamina, one side jaw assembly (comprising all parts that link to each other with jaw) is advanced to opposite side, Roller Shaft 9 and jaw guide rail 10 are along entad slippage of jaw plate frame gathering sill 2, the jaw 11 of this assembly can expose from opening part near the dental lamina rotating shaft 7 of opening one side, extract dental lamina rotating shaft 7 out, promptly replaceable dental lamina near opening.
As shown in Figure 6, on basis shown in Figure 5, lower guideway 10 has broken away from the gathering sill 2 of jaw plate frame 3 on this jaw 11, and this jaw is turned an angle to opening one side around Roller Shaft 9, another dental lamina rotating shaft 7 can be exposed from open rear section, extracts this dental lamina rotating shaft 7 out and can take out another dental lamina 1.
Shown in Fig. 7,8, the introversion dental lamina has negative camber and stuck pipe body to match, and tooth is bald tooth, except that the interdental groove groove, longitudinal groove 15, lateral trench 16 are still arranged, be used for depositing the foreign material in the chucking process, guarantee that bald tooth contacts with the stuck pipe body, non-slip in the work.
