Accompanying drawing explanation
Fig. 1 is of the present inventionly led by guide peg and is with the overall structure schematic diagram of the drilling equipment of dirt-proof boot.
Detailed description of the invention
By reference to the accompanying drawings 1, detailed explaination is made to the present invention.
According to embodiment, a kind ofly led by guide peg and be with the drilling equipment of dirt-proof boot, comprise housing 9 and be positioned at the driving shaft 8 of housing 9, the lower end of described driving shaft 8 is provided with the blind hole with guide peg 81, the right and left of the shell portion 62 of transmission cylinder 6 is provided with pilot hole 82 to be slidably matched with the guide peg 81 of described blind hole, internal spline is provided with in order to coordinate with the external splines outside the radial enlargement 71 of drilling rod 7 inside the described shell portion 62 of described transmission cylinder 6, described transmission cylinder 6 the portion integral formula of described shell portion 62 be provided with outstanding cylindrical portion 61 in order to threaded engagement side engagement in the lower end cylindrical portion 91 of described housing 9 and in the lower end wall 51 of the screw shell 5 be shifted up and down, thus described transmission cylinder 6 is shifted up and down in described blind hole, the centre of the lower end wall 51 of described screw shell 5 is provided with screwed hole 33, dirt-proof boot 34 is provided with in described screwed hole 33, described dirt-proof boot 34 is provided with the through hole 35 passed for drilling rod 7, the diameter of described through hole 35 is a bit larger tham the diameter of drilling rod 7, described dirt-proof boot 34 is connected with described screwed hole 33 threaded engagement, top pressure spring 4 is provided with thus by described transmission cylinder 6 biased downward between the end wall 63 of the perforate arranged in the top institute integral type of the described shell portion 62 of described transmission cylinder 6 and the inner end wall of described blind hole, the downside of the described shell portion 62 of described transmission cylinder 6 is provided with location shoulder 620 in order to engage with the stopper section, location 810 of the lower end being arranged on described guide peg 81, the multiple radial expansion alignment pins 631 arranged in described end wall 63 can extend out to carry out axial location with the circumferential detent engagement in the epirelief cylindrical portion 72 of the described drilling rod 7 extend in described perforate thus to described drilling rod 7 in the perforate of end wall 63 under the effect of biased element, and described epirelief cylindrical portion 72 is adjoined with described radial enlargement 71 and diameter is less than described radial enlargement 71.
Alternatively, wherein, the end of described radial expansion alignment pin 631 is provided with and skids off inclined-plane to coordinate with the inclined surface of described circumferential locating slot thus can skid off from described circumferential locating slot.
