In order to guarantee using effect and easy to use, the oblique dovetail wing 2 is plate, the dovetail-shape formula in lower part and oblique swallow
Stern notch 5 matches, and top is that trapezoidal shape is presented in both sides chamfering, after oblique dovetail groove 5 of the oblique dovetail wing 2 in lower contact 3 is inserted into, then
The compression of connector 1 is connected, is become one structure；
The first internal screw thread catching groove 7 is small in the big inner end of oral area, and internal thread circular hole channel-shaped on hole wall；
The second external screw thread discount 8 is in the conical hollow that point diameter is small, rear end diameter is big；
The 1 upper body diameter of top connection is less than lower body diameter, and the upper body that the lower body diameter of lower contact 3 is less than top connection is straight
Diameter, the upper body diameter of top connection and the lower body diameter of lower contact are identical, the lower body diameter of top connection and the upper body diameter of lower contact
Identical, the lower body of top connection and the upper body of lower contact link together in same axle center, constitute 1 centre bore of top connection and lower contact
The through-hole integral structure of 3 centre bores on the same line, the middle part of integral structure are in the cylinder that both ends inclined-plane expands outward, circle
Cylindrical top is equipped with the oblique dovetail wing 2 through oblique dovetail groove 5；
The oblique dovetail groove 5 is 3-4, and the oblique dovetail wing 2 matched is also 3-4, oblique dovetail groove and the oblique dovetail wing
Length it is identical.
A kind of interchangeable oblique wing stabilizer of the utility model it can be seen from above structure, including top connection 1, the oblique dovetail wing
2, lower contact 3 forms, and top connection 1 is inner via hole cylindrical body, and top is that internal screw thread button is connected with drill string, lower part for external thread buckle and
Lower contact 3 is connected, and has a boss in the outer circle of middle part, when top connection 1 is connect with lower contact 3, boss can be than more smoothly
The oblique dovetail wing of the limitation in lower contact 3, guarantees the normal use of tool, what is connect with top connection 1 is that 3 top of lower contact is
Internal screw thread button is connected with top connection 1, and lower part is that external thread buckle is connected with drill string, and outer circle presentation in middle part is cylindric, columned
One, that is, box end is provided with the oblique dovetail groove in three to four roads, and does not penetrate through, length and the corresponding tiltedly dovetail wing 2 are corresponding,
Just the oblique dovetail wing 2 is inserted, and the oblique dovetail wing 2 is plate, under dovetail-shape formula and dovetail groove match, thereon to lean now to one side, then to the other
Trapezoidal shape is presented in angle, after dovetail of the oblique dovetail wing 2 in lower contact 3 is inserted into, then connects the compression of connector 1, becomes one completely
Product, when requiring replacement, only need to lay down top connection 1 after the oblique dovetail wing 2 is taken out out of lower contact dovetail groove, change
The required new oblique dovetail wing 2 just, guarantees the normal use of stabilizer.
In order to guarantee using effect, the top connection 1 is inner via hole cylindrical body, and top is internal screw thread button and drill string phase
Even, lower part is that external thread buckle is connected with lower contact 3, there is a boss in the outer circle of middle part, when top connection 1 is connect with lower contact 3,
Boss can guarantee the normal use of tool, connect with top connection 1 than more smoothly limiting the oblique dovetail wing in lower contact 3
What is connect is that 3 top of lower contact is connected for internal screw thread button with top connection 1, and lower part is that external thread buckle is connected with drill string, and middle part outer circle is in
Existing cylindric, at columned one, that is, box end is provided with the oblique dovetail groove in three to four roads, and does not penetrate through, length and phase
The oblique dovetail wing 2 answered is corresponding, and just the oblique dovetail wing 2 is inserted.
The oblique dovetail wing 2 is plate, under dovetail-shape formula and dovetail groove match, be thereon that ladder is presented in both sides chamfering
Shape after dovetail of the oblique dovetail wing 2 in lower contact 3 is inserted into, then connects the compression of connector 1, becomes a complete product, when
When needing replacing, the oblique dovetail wing 2 is taken out out of lower contact dovetail groove after only need to laying down top connection 1, needed for changing newly
The oblique dovetail wing 2 just, guarantees the normal use of stabilizer.
