DETAILED DESCRIPTION

[0027] The application will be further described in detail below with reference to the accompanying drawings.

As Figures 1-8 shown, the mechanism includes a synchronous gear 1, two flip plates 2, two double-wheel structures 3, a first connecting piece 4, a second connecting piece 5, a third connecting piece 6, two first same-motion shafts 7, two second same-motion shafts 8, a connecting shaft 9, three springs 10, a double clamping spring 81 and a three clamping spring 71, etc.

[0029] The synchronous gear 1 is substantially cylindrical, and has two sides in one direction and two ends in another direction. The two sides of the synchronous gear 1 are provided with a plurality of first side teeth 11, and the two flip plates 2 each include a plate body 21 provided with a plurality of second side teeth 22 on one side. The plate body 21 of each flip plate 2 is installed by the cooperation of the first side teeth 11 and the second side teeth 22. The side of the plate body 21 of the flip plate 2, on which the second side teeth 22 are located, is further provided with a mounting shaft 23 movably installed through a shaft hole structure. The plate body 21 can be flipped around the mounting shaft 23, and the synchronous gear 1 can be rotated when the plate body 21 is flipped.

[0030] The two ends of the synchronous gear 1 are each provided with two groups of first sawteeth 12, and the first sawteeth 12 at the two ends are each installed in cooperation with a double-wheel structure 3. The double-wheel structure 3 includes two cam wheels 31 connected to each other, and each cam wheel 31 is provided with second sawteeth 32. The two groups of first sawteeth 12 at the two ends of the synchronous gear 1 are each installed in cooperation with the second sawteeth 32 of the two cam wheels 31 of the double-wheel structure 3. When the synchronous gear 1 rotates, the first sawteeth 12 thereon will climb along the second sawteeth 32 of the double-wheel structure 3.

[0031] In addition, the two groups of first sawteeth 12 of the synchronous gear 1 and the second sawteeth 32 of each double-wheel structure 3 are both hollow in the middle to allow the shaft structure to pass through.

[0032] One end of the synchronous gear 1 is provided with a third connecting piece 6 in contact with the double-wheel structure 3 at the end. One end of each of the two second same-motion shafts 8 passes through the third connecting piece 6, the double-wheel structure 3, the synchronous gear 1, and the other double-wheel structure 3 in sequence, and is connected by a double snap spring 81 at the end. The other end of each of the two second same-motion shafts 8 passes through a connecting shaft 9, and the connecting shaft 9 is also in contact with the third connecting piece 6.

[0033] One end of the connecting shaft 9 is provided with two first through holes 91, and each of the two second same-motion shafts 8 passes through one of the two first through holes 91. The other end of the connecting shaft 9 passes through the second connecting piece 5, one of the springs 10, and the first connecting piece 4 in sequence.

[0034] Each of the two sides of the second connecting piece 5 is provided with a clamping strip 51, and each of the two sides of the third connecting piece 6 is provided with a clamping groove 61. The two clamping strips 51 are clamped and installed in the two clamping grooves 61, so that the second connecting piece 5 and the third connecting piece 6 are clamped and installed. Thus, when installed, the second connecting piece 5 and the third connecting piece 6 clamp the connecting ends of the two second same-motion shafts 8 and the connecting shaft 9 in the middle.

[0035] One end of the two first connecting shafts 7 is connected to the second connecting member 5, and the other end of the two first connecting shafts 7 respectively penetrates the other two springs 10 and the first connecting member 4, and is connected to the connecting shaft 9. Specifically, the two first connecting shafts 7 and the connecting shaft 9 penetrate the first connecting member 4 and are connected by a three-clamp spring 71.

[0036] Preferably, the second connecting member 5 has three second penetrating holes 52, and the two first connecting shafts 7 and the connecting shaft 9 respectively penetrate the three second penetrating holes 52.

[0037] In use, when the plate body 21 of the turnover plate 2 is turned over, the synchronous gear 1 is driven to rotate by the cooperation of the second side teeth 22 and the first side teeth 11, and the first sawtooth 12 at both ends of the synchronous gear 1 will respectively climb along the second sawtooth 32 of the two double-wheel structures 3, so as to press and compress the two double-wheel structures 3.

[0038] Among them, at the end of the synchronous gear 1 away from the third connecting member 6, the double-wheel structure 3 at this end will compress the ends of the two second connecting shafts 8 after being stressed, and pull the two second connecting shafts 8, so as to drive the connecting shaft 9 and the first connecting member 4 to move towards the side close to the synchronous gear 1, so as to compress the spring 10 to generate torsion.

[0039] And at the end of the synchronous gear 1 close to the third connecting member 6, the double-wheel structure 3 at this end will compress the third connecting member 6 and the second connecting member 5 after being stressed, so as to move them away from the synchronous gear 1, so as to further improve the effect of compressing the spring 10 to generate torsion.

[0040] The above only describes some embodiments of the present application. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are all within the protection scope of the present application.
