Description of reference numerals: the nut comprises a rotary nut 1, a limiting jackscrew 2, a connecting rod 3, an upper movable ball 11, an inner screw thread 12, a nut through cavity 13, a lower movable ball 14, a rod through hole 21, an outer screw thread 22, a hexagonal screw head 31 and a tail screw thread 32.
Detailed Description
Referring to fig. 1 to 5, the technical solution adopted by the present embodiment is: the connecting rod comprises a limiting jackscrew 2, a rotating nut 1 used for connecting the limiting jackscrew 2 and a connecting rod 3 of a connecting pin shaft, wherein the inner cavity of the rotating nut 1 is in threaded connection with the outer wall of the limiting jackscrew 2, the connecting rod 3 penetrates through the limiting jackscrew 2, one end of the connecting rod 3 is connected with the pin shaft screw hole, and the rotating nut 1, the limiting jackscrew 2 and the connecting rod 3 are made of alloy steel. The steel alloy is adopted for manufacturing, so that the hardness of the extractor is increased, and the service life of the extractor is prolonged.
The rotary nut 1 comprises an upper movable ball 11, an inner screw thread 12, a nut through cavity 13 and a lower movable ball 14, the upper end of the rotary nut 1 is provided with the upper movable ball 11, the lower end of the rotary nut 1 is provided with the lower movable ball 14, the inner cavity of the rotary nut 1 is the nut through cavity 13, and the nut through cavity 13 is provided with the inner screw thread 12. The nut leads to chamber 13 and is convenient for spacing jackscrew 2 to connect swivel nut 1 to carry out the spacing jackscrew 2 of threaded connection through interior screw thread 12, when using, activity ball 11 and lower activity ball 14 can alleviate swivel nut 1 and external frictional force on it, the inner chamber of spacing jackscrew 2 is pole through-hole 21, and the outer wall of spacing jackscrew 2 is equipped with outer screw thread 22.
