The upper millstone be platy structure, it is provided with first through hole in centre position, in vertical side be provided with to
Under the first convex navel for leaning out, the first through hole（6）Trapezium structure for bottom be less than upper bottom；
The lower millstone is made up of two pieces of symmetrically arranged lower mill jigsaw, and it is clamped between two first convex navels,
It is described it is lower mill jigsaw include the platysome of platy structure, positioned at the lower section of the flat board body side surface and with the described first convex navel
Second convex navel of contacts side surfaces and be arranged on the platysome upper surface boss, the outer wall of the boss can be along described
The inwall of first through hole slides, and the inwall of two boss combines to form concentric and be mutually communicated with the first through hole
Second through hole.
As a further improvement on the present invention, to be provided with first parallel with its inwall on the first through hole inwall recessed
The sliding block that can be slided along first groove is provided with groove, the outer wall of the boss.
As a further improvement on the present invention, annular is provided between the lower surface of the upper millstone and the lower millstone
First elastic washer, the outer wall of the endoporus and the boss of first elastic washer contacts with each other.
As a further improvement on the present invention, the medial surface of the described first convex navel is provided with the second groove, the first convex navel
Contacted with each other between the described second convex navel by the second elastic washer being arranged in second groove
The beneficial effects of the present invention are, upper millstone and lower millstone are set, and both are connected by first through hole with boss,
When actual use, upper millstone and lower millstone are connected with each other by the auxiliary connection through the second through hole, on active force is acted on
During mill, the structure of first through hole and boss make it that jigsaw is ground under two mutually to be compressed, so that mutually being pressed between the second convex navel
Tightly, the purpose for preventing loosening is played, the problem of running into the prior art is solved.

Embodiment
The embodiment to the present invention is described in further detail below.
As shown in figure 1, the present invention includes upper millstone 2 and lower millstone 4, wherein：
The upper millstone 2 is platy structure, and it is provided with first through hole 6 in centre position, is provided with vertical side
The the first convex navel 8 leant out downwards, the first through hole（6）Trapezium structure for bottom be less than upper bottom；
The lower millstone 4 by two pieces it is symmetrically arranged it is lower mill jigsaw 10 constitute, its be clamped in two first convex navels 8 it
Between, the lower mill jigsaw 10 includes the platysome 12 of platy structure, positioned at the side of platysome 12 lower section and with described the
One convex navel 8 medial surface contact the second convex navel 15 and be arranged on the platysome 12 upper surface boss 14, it is described convex
The outer wall of platform 14 can be slided along the inwall of the first through hole 6, and the inwall of two boss 14 combines to be formed and described the
One through hole 6 is concentric and the second through hole 16 for being mutually communicated.
As a further improvement on the present invention, to be provided with first parallel with its inwall on the inwall of first through hole 6 recessed
The sliding block that can be slided along first groove is provided with groove, the outer wall of the boss 14.
As a further improvement on the present invention, it is provided with annular between the lower surface and the lower millstone 4 of the upper millstone 2
The first elastic washer 17, the outer wall of the endoporus of first elastic washer 17 and the boss 14 contacts with each other.
As a further improvement on the present invention, the medial surface of the described first convex navel 8 is provided with the second groove 18, and described first is convex
Contacted with each other between navel 8 and the second convex navel 15 by the second elastic washer 20 being arranged in second groove 18.
The concrete principle of the present invention is as follows：
（1）Upper millstone 2 and lower millstone 4 are set, and both are connected by first through hole 6 with boss 14, when actual use, led to
Upper millstone 2 and lower millstone 4 are connected with each other by the auxiliary connection crossed through the second through hole 16, when active force acts on upper millstone 2, the
The structure of two through holes 16 and boss 14 make it that jigsaw 10 is ground under two mutually to be compressed, so that mutually being pressed between the second convex navel 15
Tightly, the purpose for preventing loosening is played, the problem of running into the prior art is solved.
（2）The inwall of first through hole 6 and the bottom angle of first through hole 6 are obtuse angle, when between upper millstone 2 and lower millstone 4
During anti-raw mutually extruding, the sliding block on boss 14 is slided along the first groove parallel with first through hole 6, the process production of the slip
Raw horizontal force is oppositely arranged, therefore the mutually compression of jigsaw 10 is ground under two, so that the second convex navel 15 compresses side bearing；
（3）First elastic washer 17 is set, for setting certain buffering between upper millstone 2 and lower millstone 4, while
Upper millstone 2 and lower millstone 4 unload and deformation force are discharged after power so that upper millstone 2 and lower millstone 4 mutually reset；
（4）Second elastic washer 20 is set between the first convex navel 15 of convex navel 8 and second, is that the first convex navel 8 and second is convex
There is provided buffering when navel 15 is mutually moved.
Above example is only a kind of present invention embodiment therein, and it describes more specific and detailed, but can not
Therefore it is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection model of the present invention
Enclose.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
