It is equipped with ball, force block, spring and supporting rod, the part of the ball is exposed outside the head in correcting portion, and ball can not lead to
It crosses through-hole entirely to move out outside the head in correcting portion, the lower face of the force block and ball contact, and the upper surface of force block
It is contacted with spring, oil storage part is set in the force block, lubricating oil is adsorbed in the oil storage part, pass through ball and force block
Slow pcrmanent lubrication, the lower end of the supporting rod and spring contact are contacted, the upper end of the supporting rod is provided with interconnecting piece, described
Interconnecting piece and through-hole or shank are fixed, for making supporting rod fix.
As preferred：The ball uses hard metal material, and the surface of the ball is provided with lubricant passage way.
As preferred：The lower face centrally disposed fluted one of the force block, the groove one are the arc of indent, are used
It is contacted in ball realization face.
As preferred：The spring is set in the upper surface of force block, and the upper surface setting fluted two of force block, institute
It is annular to state groove two, for being further clamped spring.
As preferred：The force block is provided centrally with oil storage hole, and the oil storage hole runs through the lower face of force block, institute
Oil storage part is stated to be located in oil storage hole.
As preferred：The oil storage part is absorption type oil storage, and the oil storage part is provided with one or more in oil storage hole,
And isolation board is provided between adjacent oil storage part, oil leak aperture is provided on the isolation board.
As preferred：The through-hole is stepped hole in shank, and fixture block, the fixture block and rank are provided on the supporting rod
It is in contact at the ladder in terraced hole, for judging and prompting the bottom end of supporting rod in the position of through-hole.
As preferred：The top of the interconnecting piece and through-hole is threadedly coupled.
As shown from the above technical solution, the advantageous effect of this practicality is：
Using the high-freedom degree of ball, during correcting, rolls when ball stress and moved into through-hole, be conducive to unload
Power reduces the impact that the head in correcting portion is subject to,；The setting of force block, the power be conducive between spring and ball are transmitted, are avoided
Due to the arc moulding of ball cause it is irregular with stress when spring power transmission；It is provided with oil storage part in force block, realizes to ball
Pcrmanent lubrication.
