731 the second inclined-plane 732 position it is corresponding in the position on the first inclined-plane 724 with circular through hole 721, stud 80 can be made successively to wear
Cross right-angled trapezium block 73 and right angle trigonometry block 72.
On the basis of the above embodiments, right-angled trapezium block 73 is provided with through the second inclined-plane 732 and first side 734
Waist-shaped hole, right-angled trapezium block 73 are set on stud 80 by waist-shaped hole.Specifically, the middle and upper part for being located at the second inclined-plane 732 is set
It is equipped with waist-shaped hole, the axis direction of waist-shaped hole is consistent with the inclined direction on the second inclined-plane 732, and waist-shaped hole runs through the second inclined-plane 732
With first side 734, the wide outer diameter slightly larger than stud 80 in the hole of waist-shaped hole prevents right-angled trapezium block 73 from swinging on stud 80.
The waist-shaped hole that right-angled trapezium block 73 is arranged, provides the upper and lower displacement that right-angled trapezium block 73 is moved along stud 80, increases right angle
Adjustable range of the trapezoid block 73 to sealing strip.It is understood that position and circular through hole of the waist-shaped hole on the second inclined-plane 732
721 the first inclined-plane 724 position it is corresponding, stud 80 can be made to sequentially pass through right-angled trapezium block 73 and right angle trigonometry block 72.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
