The base endoporus of described male seat both sides is provided with female joint axle sleeve, the endoporus of described male seat is installed
There is male joint axle sleeve, the two ends periphery of described screw shaft is disposed with screw thread in opposite direction and passes through
Screw thread is symmetrically connected with the nut axle sleeve that outside is close to female joint axle sleeve and male joint axle sleeve, described
In cone on the lateral wall of nut axle sleeve, on described female joint axle sleeve and the inner headed face of male joint axle sleeve
It is disposed with the taper seat matched with nut axle sleeve.
Supplementing as one of the present utility model, the inside of described screw shaft has the polygon of through two ends
Shape through hole.
As further supplementing, described polygonal through hole is regular hexagon through hole.
Supplement as to the one of technical scheme described in the utility model, outside the middle part of described screw shaft
The support round platform contacted outside a circle it is disposed with male joint axle sleeve inner headed face on disc.
Further, the lateral wall of described nut axle sleeve is that outboard end diameter is big, medial extremity diameter is little
Cone.
Further, the screw thread at described screw shaft two ends is trapezoidal thread or saw-tooth thread.
Beneficial effect
This utility model relates to a kind of quick-detaching pin axle construction connecting large type drill guide holder and base,
Rational in infrastructure ingenious, utilize contrary screw thread to make nut shaft set move axially, and utilize inclined-plane to lock,
As long as filling up lubricating oil at screw shaft and nut axle sleeve, periodically rotating screw shaft, whole bearing pin total performance is not
Can be because of motionless and corrosion, dismounting bearing pin the most easily, substantially increases the efficiency of rig transition.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model is depending on partly cuing open structure chart.
Diagram: 1, screw shaft；2, nut axle sleeve；3, polygonal through hole；4, male joint axle sleeve；5, male seat；
7, round platform is supported；8, base.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further.Only should be understood that these embodiments
For this utility model being described rather than limiting scope of the present utility model.In addition, it is to be understood that reading
After the content that this utility model is lectured, this utility model can be made various changing by those skilled in the art
Moving or amendment, these equivalent form of values fall within the application appended claims limited range equally.
As it is shown in figure 1, embodiment of the present utility model relates to a kind of connection large type drill guide holder and the end
The quick-detaching pin axle construction of seat, including base 8, screw shaft 1 and the male seat 5 connecting guide holder, described
Male seat 5 be positioned at the inside of base 8, described screw shaft 1 is horizontally through the interior of base 8 and male seat 5
Hole, is provided with female joint axle sleeve 6 in base 8 endoporus of described male seat 5 both sides, described male seat 5
Endoporus is provided with male joint axle sleeve 4, the two ends periphery of described screw shaft 1 is disposed with in opposite direction
Screw thread and be symmetrically connected with outside by screw thread and be close to female joint axle sleeve 6 and male joint axle sleeve 4
Nut axle sleeve 2, in cone on the lateral wall of described nut axle sleeve 2, described female joint axle sleeve 6 He
The taper seat matched with nut axle sleeve 2 it is disposed with on the inner headed face of male joint axle sleeve 4.
As a kind of embodiment of the present utility model, just may be used when rotating forward screw shaft 1 when of use
So that the nut axle sleeve 2 at its two ends axially inwardly moves, due to the effect of taper seat, nut axle sleeve 2 with
Will produce extruding force between female joint axle sleeve 6 and male joint axle sleeve 4, and produce the biggest friction
Power, it is achieved that being relatively fixed of male seat 5 and base 8.
When rotating backward screw shaft 1, the nut axle sleeve 2 at its two ends can be made axially outwardly to move, spiral shell
Female axle sleeve 2 separates unclamp with female joint axle sleeve 6 and male joint axle sleeve 4, thus can be by whole spiral shell
Bar axle 1 takes out together with nut axle sleeve 2.
Supplementing as one of the present utility model, it is many that the inside of described screw shaft 1 has through two ends
Limit shape through hole 3, conveniently utilizes existing instrument to make screw shaft 1 rotate.
As further supplementing, described polygonal through hole 3 is regular hexagon through hole, often can use
Die nut be inserted into polygonal through hole 3 screw shaft 1 rotated.
Supplement as to the one of technical scheme described in the utility model, the middle part of described screw shaft 1
It is disposed with the support round platform 7 contacted with male joint axle sleeve 4 inner headed face outside a circle on periphery, opens and prop up
Support effect, improves the stability that screw shaft 1 rotates.
Further, the lateral wall of described nut axle sleeve 2 is that outboard end diameter is big, medial extremity diameter is little
Cone.
Further, the screw thread at described screw shaft 1 two ends is trapezoidal thread or saw-tooth thread, ladder
Shape screw thread or saw-tooth thread have bigger transmission power, can improve the coupling mechanism force of pin shaft structure.
Pin shaft structure described in the utility model is the most ingenious, utilizes contrary screw thread to make nut shaft set axially
Mobile, and utilize inclined-plane to lock, as long as filling up lubricating oil at screw shaft and nut axle sleeve, periodically turn
Dynamic screw shaft, whole bearing pin total performance will not be because of motionless and corrosion, and dismounting bearing pin the most easily, carries significantly
The high efficiency of rig transition.
