The material of bead 33 is plastics.
The material of second bull stick 25 is stainless steel.
Operation principle：In presentation process, by rotating clockwise the second bull stick 25, the second bull stick 25 drives the first screw mandrel 23
Rotated clockwise with the second screw mandrel 24, the first screw mandrel 23 drives the first nut 19 to left movement, and the first nut 19 drives first to insert
Bar 21 to left movement, while the first nut 19 drive on the left of sliding block 18 on slide rail 17 to left movement, the second screw mandrel 24 drives
Second nut 20 is moved right, and the second nut 20 drives the second inserted link 22 to move right, while on the right side of the drive of the first nut 19
Sliding block 18 is moved right on slide rail 17, consolidates the first mounting rod 8 and the 3rd mounting rod 32 when the first inserted link 21 is moved to the left
Live calmly, and the second inserted link 22 is moved right to after being fixed the second mounting rod 28, stop operating the second bull stick 25, then leads to
The first bull stick 14 of rotation is crossed, the first bull stick 14 drives tellurion 13 to rotate, to demonstrate solar eclipse phenomenon.
Because also including steel wire rope 2, guide rail 3, guide pin bushing 4, spring 5, first connecting rod 6, block rubber 7, the and of second connecting rod 10
Fix bar 11, installs the left upper portion of case 1 and is connected with second connecting rod 10, the antetheca top of second connecting rod 10 is connected with fix bar 11, the
The right upper portion of two connecting rod 10 is connected with slidingtype on guide rail 3, guide rail 3 and is connected with guide pin bushing 4, and guide pin bushing 4 coordinates with guide rail 3, and guide pin bushing 4 is left
Middle side part is connected with steel wire rope 2, and steel wire rope 2 is fixed in fix bar 11, is connected with the right side of guide pin bushing 4 and guide rail 3 between right side
Spring 5, the right side of guide pin bushing 4 is symmetrically connected with first connecting rod 6, and the right-hand member of first connecting rod 6 is connected with block rubber 7, block rubber 7 and tellurion
13 contacts, when the first bull stick 14 drive tellurion 13 to turn in solar eclipse phenomenon, steel wire rope 2 are untied from fix bar 11, is drawn
Dynamic steel wire rope 2 is moved downward, and steel wire rope 2 pulls guide pin bushing 4 and connecting rod on guides 3 to left movement, and then connecting rod drives rubber
Blob of viscose 7 is to left movement, after block rubber 7, which leaves, to be contacted with tellurion 13, when rotating the globe 13 in solar eclipse phenomenon, unclamps steel
Cord 2, guide pin bushing 4 and connecting rod are moved right in the presence of the elastic force of spring 5, and then connecting rod drives block rubber 7 to move right,
When block rubber 7 is moved right to when being contacted with tellurion 13, then steel wire rope 2 is fixed on fix bar 11, so, block rubber
7 just can play fixation to tellurion 13.
Because it is light material to install the material of case 1, weight can be reduced, facilitates taking for teacher.
Because the material of tellurion 13 be plastics, when to rotate the globe 13 when, more fast.
Because the material of bead 33 be plastics, can alleviator weight.
Because the material of the second bull stick 25 is stainless steel, stainless steel corrosion resistance and acid resistance are strong, make the use longevity of device
Life is longer.
Embodiment described above only expresses preferred embodiment of the present utility model, and it describes more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model the scope of the claims.It should be pointed out that for the common of this area
For technical staff, without departing from the inventive concept of the premise, some deformations can also be made, improves and substitutes, these are all
Belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
