Detailed Description
Example (b):
as shown in fig. 1 and 6, the rusted bolt breaking and detaching device comprises an annular frame 4, a cutter assembly, a force application disc 9, a force application rod 10, a fixed screw rod 2 and a second cutter 3;
the side wall of the annular frame 4 is provided with a fixing threaded hole 41 and an inserting hole 42 which are oppositely arranged, the fixing screw rod 2 is inserted into the fixing threaded hole 41 to be in threaded connection with the fixing threaded hole and is fixed through the screw cap 1, and the end part of one end, extending into the annular frame 4, of the fixing screw rod 2 is fixedly connected with the second cutter 3. Two limit convex strips 421 are symmetrically arranged on the inner wall of the inserting hole 42.
The cutter subassembly includes first cutter 5 and telescopic link, the telescopic link includes interior pole 6, outer tube 7 and threaded rod 8, 7 inner walls of outer tube are equipped with the screw thread, pole 6 in 7 upper ends grafting of outer tube, lower extreme threaded connection threaded rod 8, 8 up end of threaded rod are equipped with slot rolling 81, roll in the slot rolling 81 and be connected with ball 82, 6 lower extremes of interior pole support on ball 82, leave the clearance between 6 lower extremes of interior pole and the 8 upper ends of threaded rod. 6 outer wall symmetries of interior pole are equipped with two spacing grooves 61, interior pole 6 passes spliced eye 42, spacing sand grip 421 cards are gone into in the spacing groove 61, the fixed 4 outer walls of annular frame in outer tube 7 upper end, the first cutter 5 of the 6 upper end joints of interior pole, the 5 lower extremes of first cutter are equipped with dop 51, but interior pole 6 upper end is equipped with joint dop 51's draw-in groove 62, dop 51 card goes into draw-in groove 62.
