The specific embodiment

Be described in further detail for example with regard to specific implementation method of the present invention by accompanying drawing 1,2,3 below.

Press Fig. 1, right figure is the using method of common buildings template clamping, put on polished rod 5 earlier, oblique cover 3 and wedge 4 are all loaded onto in two, strike in the tangible tiltedly cover 3 with the wedge 4 of hammer earlier by one of E steering handle, the other end is by the clamp installation tool that is inserted in shown in Figure 3, when two handles 13 to K to firmly the time, retaining sour jujube 8 nips in the polished rod 5 and withstands vice body 12 the back is sliding, to tiltedly overlap 3 pushes ahead, because of having sandwiched a sleeve clamp, polished rod 5 other ends withstand the another side template, so can not retreat, tiltedly cover 3 can only advance to the T direction, rotate the ramp blocks 6 of oblique circular cylinder shape, make the inclined-plane contact the afterbody of wedge 4, its effect is the ramp blocks 6 that also promotes to be contained on the thrust groove 14 when thrust groove 14 promotes tiltedly to overlap 3, wedge 3 to T to synchronous propelling, the purpose that ramp blocks 6 is set is because tiltedly overlap 3, wedge 4, the size of polished rod 5 has error, make wedge 4 enter have in the oblique cover 3 have deeply shallow, ramp blocks 6 is to be used for adjusting this error to guarantee wedge 4 and tiltedly cover 3 propelling synchronously, if only withstand wedge 4, tiltedly overlap motionlessly, thrust groove 14 just advances and is obstructed.When pine instrument when pincers, the bounce of template will be oppressed pad 2, tiltedly overlap 3, tiltedly cover 3 compressing wedges 4 make it bite polished rod 5, can not retreat, when two handles 13 of instrument pincers are opened 130 ° of-150 ° of angles, adjust the top that retaining sour jujube 8 is changeed on screw 17 tops, make the interlock of sour jujube 8 disengagings and polished rod 5, the entire tool pincers can push forward and make thrust groove 14 press close to oblique cover 3, repeat handle 13 and press the K direction firmly, oblique cover 3 is pushed to back again and is and then pinned by wedge 4, repeatedly work repeatedly, shift template onto precalculated position till, ramp blocks 6 is rotated make the width position of ramp blocks 6 push down wedge 4 again, thrust groove 14 then is not pressed onto oblique cover 3, repeat the above method that advances, become thrust groove 14 and withstand ramp blocks 6, withstand wedge 4 again and be pressed in the oblique cover 3, make wedge 4 sting real polished rod 5 more, perhaps clamp installation tool is withdrawed from polished rod 5, enter in the oblique cover with the heavy wedge 4 that knocks of hammer, locking to reinforce.

Dismounting uses demounting tool 18 as Fig. 2, in the foregoing invention content 3) o'clock say very clear no longer repetition.

As the above example of Fig. 3, the tooth of wedge 4 and retaining sour jujube with 90 ° of about at interval 2.5mm of wedge angle about, crossing conference as angle stings not tight, the too small tooth that then collapses easily, the many contact surfaces of the interval too small number of teeth greatly then difficulty are stung into polished rod 5, the number of teeth is too small, and then to damage polished rod 5 serious, once testing wedge does not scribe tooth and reduces gradient again to increase frictional force yet, the full friction lock of using, if polished rod 5, wedge 4, when tiltedly cover 3 contact surfaces were dry hair sides, its frictional force increase also was limited, and its normal pressure generally is ten times of frictional force, can its frictional force increase then depend on the intensity of oblique cover 3 withstand frictional force increases needed normal pressure, so also be limited.But when being stained with sliding agent such as water, oil, paint, wet cement slurry when contact surface, because friction factor has diminished, so the performance that locks is unsettled, add that gradient is too little, dismounting is had any problem, so do not adopt.Once replaced cylinder ramp blocks 6 with spring or plane wedge in the trial-production, all feasible, but effect is undesirable, and spring force kicks the beam and then pushes away motionless wedge 4, and excessive then advance distance can dwindle, and plane wedge method structure is than complex loose, and adjusting range is also wide inadequately.
