The inwall of through hole slides, and the inwall of two described boss combines formation and described first through hole concentric and be mutually communicated second
Through hole.
As a further improvement on the present invention, described first through-hole wall is provided with first parallel with its inwall recessed
Groove, the outer wall of described boss is provided with the slide block slided along described first groove.
As a further improvement on the present invention, annular it is provided with between lower surface and the described lower millstone of described upper millstone
First elastic washer, the endoporus of described first elastic washer contacts with each other with the outer wall of described boss.
As a further improvement on the present invention, the medial surface of described first convex umbilicus is provided with the second groove, described first convex umbilicus
And contacted with each other by the second elastic washer being arranged in described second groove between described second convex umbilicus
The beneficial effects of the present invention is, arrange upper millstone and lower millstone, both are connected with boss by the first through hole, actual
During use, by upper millstone and lower millstone being connected with each other through the auxiliary connection of the second through hole, when active force acts on upper millstone
Time, the first through hole making mill jigsaw under two mutually compress with the structure of boss, so that mutually compressing between the second convex umbilicus, rising
To preventing the purpose that loosens, solve the problem run in prior art.

Detailed description of the invention
Below the detailed description of the invention of the present invention is described in further detail.
As it is shown in figure 1, the present invention includes upper millstone 2 and lower millstone 4, wherein:
Described upper millstone 2 is platy structure, and it is provided with the first through hole 6 in centre position, is provided with downwards in vertical side
The the first convex umbilicus 8 leant out, the vertical section of described first through hole 6 is the trapezium structure upper end of more than of going to the bottom；
Described lower millstone 4 is made up of two pieces of symmetrically arranged lower mill jigsaw 10, and it is clamped between two described first convex umbilicuss 8,
Described lower mill jigsaw 10 includes the platysome 12 of platy structure, is positioned at the lower section of described platysome 12 side and first convex with described
Second convex umbilicus 15 of the medial surface contact of umbilicus 8 and be arranged on the boss 14 of upper surface of described platysome 12, described boss 14
Outer wall can slide along the inwall of described first through hole 6, the combination of the inwall of two described boss 14 is formed leads to described first
Hole 6 concentric and the second through hole 16 being mutually communicated.
As a further improvement on the present invention, described first through hole 6 inwall is provided with first parallel with its inwall recessed
Groove, the outer wall of described boss 14 is provided with the slide block slided along described first groove.
As a further improvement on the present invention, it is provided with annular between lower surface and the described lower millstone 4 of described upper millstone 2
The first elastic washer 17, the endoporus of described first elastic washer 17 contacts with each other with the outer wall of described boss 14.
As a further improvement on the present invention, the medial surface of described first convex umbilicus 8 is provided with the second groove 18, described first convex
Contacted with each other by the second elastic washer 20 being arranged in described second groove 18 between umbilicus 8 and described second convex umbilicus 15.
The concrete principle of the present invention is as follows:
(1) arranging upper millstone 2 and lower millstone 4, both are connected with boss 14, time actually used, by wearing by the first through hole 6
Upper millstone 2 and lower millstone 4 are connected with each other by the auxiliary connection crossing the second through hole 16, and when active force acts on upper millstone 2, second leads to
Hole 16 makes mill jigsaw 10 under two mutually compress with the structure of boss 14, so that mutually compressing between the second convex umbilicus 15, rises
To preventing the purpose that loosens, solve the problem run in prior art.
The inwall of (2) first through holes 6 and the bottom angle of the first through hole 6 are obtuse angle, between upper millstone 2 and lower millstone 4
When anti-life mutually extrudes, the slide block on boss 14 slides along the first groove parallel with the first through hole 6, and the process of this slip is produced
Raw horizontal force is oppositely arranged, and therefore grinds jigsaw 10 under two and mutually compresses, so that side bearing is compressed by the second convex umbilicus 15；
(3) the first elastic washer 17 is set, for arranging certain buffering between upper millstone 2 and lower millstone 4, simultaneously at upper mill
Dish 2 and lower millstone 4 discharge deformation force after unloading power so that upper millstone 2 and lower millstone 4 mutually reset；
(4) the second elastic washer 20 is set between the first convex umbilicus 8 and the second convex umbilicus 15, is the first convex umbilicus 8 and the second convex umbilicus 15
When mutually moving, it is provided that buffering.
Above example is only the present invention a kind of embodiment therein, and it describes more concrete and detailed, but can not
Therefore the restriction to the scope of the claims of the present invention it is interpreted as.It should be pointed out that, for the person of ordinary skill of the art,
Without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into the protection model of the present invention
Enclose.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
