End cap is mounted in the periphery of protecting crust 10.Motor 1 and vertical pivot 2 are arranged in the space of a closing, when experiment is more safe and reliable.
The contact area of model and desktop can be increased using pedestal 9, when experiment is more reliable and more stable.
As a further refinement of the present invention, the 3rd body of rod 25 is provided between upper connecting rod 12 and elastic rod 8, the 3rd body of rod
25 one end and the lower end of upper connecting rod 12 are hinged, and the other end and elastic rod 8 of the 3rd body of rod 25 are hinged.Can be with using the 3rd body of rod 25
Increase the distance between elastic rod 8 and upper connecting rod 12 so that elastic rod 8 move when more nimbly and freely.
The present invention is in the specific implementation：Jacking block 14 is triangular structure of right angle, and the depth of small-bore groove is more than sliding block 11
Length, when initial, as shown in Fig. 2, elastic rod 8 is clamped with connector sleeve 7, the inserted link 23 of 12 lower end of upper connecting rod and inserting on lower link 13
Groove is clamped, and a right-angle side of jacking block 14 is contacted with lower link 13, and gap is left between the slot bottom of sliding block 11 and small-bore groove, is limited
Gap is left between via on position block 21 and sliding block 11.When student's rotating vane 4, blade 4 is driven by linking arm 5 and turned round
Axis 3 rotates together, and rotating shaft 3 drives vertical pivot 2 to rotate together by the cooperation of elastic rod 8 and connector sleeve 7, when the rotation speed of blade 4
When degree reaches the maximum speed of motor 1, under the action of the centrifugal force, sliding block 11 is moved to the direction away from vertical pivot 2, due to inserted link 23
It is clamped with the slot on lower link 13, so upper connecting rod 12 is not active, second spring 16 is elongated, at limited block 21 and via
Sliding block 11 be in contact after, with the movement of sliding block 11, upper connecting rod 12 rotates counterclockwise, and the first spring 15 is elongated, the first bar
Body 18 is moved to the direction away from vertical pivot 2, and drives jacking block 14 to rotate counterclockwise by second body of rod 19, jacking block 14 and lower link
13 right-angle sides being in contact gradually erect, and rotate clockwise lower link 13, and lower link 13 turns upwards close to one end of elastic rod 8
Dynamic, resetting spring 17 is elongated, and lower link 13 is rotated down close to one end of sliding block 11 so that the inserted link 23 of 12 lower end of upper connecting rod
Separated with the slot on lower link 13, since second spring 16 is elongated, so at this time under the contraction of second spring 16,
The lower end of upper connecting rod 12 is promptly close to sliding block 11, while drives elastic rod 8 to be moved to 11 direction of sliding block by the 3rd body of rod 25,
Make elastic rod 8 and the card slot quick separating on connector sleeve 7, so that vertical pivot 2 is separated with rotating shaft 3, as shown in figure 3, rotating shaft 3 is again
During rotation, vertical pivot 2 will not rotate therewith；After blade 4 stops rotating, sliding block 11 is close to vertical pivot 2, and limited block 21 is with sliding
Block 11 separates, and under the action of resetting spring 17, lower link 13 rotates counterclockwise, and lower link 13 is downward close to one end of elastic rod 8
Rotate, lower link 13 is rotated up close to one end of sliding block 11, since the first spring 15 is in elongated condition, so in the first bullet
Under the action of spring 15, upper connecting rod 12 rotates clockwise, and elastic rod 8 is blocked again with the card slot on connector sleeve 7 by the 3rd body of rod 25
Connect, while the inserted link 23 of 12 lower end of upper connecting rod is clamped again with the slot on lower link 13, is returned to original state, such as Fig. 2 institutes
Show.The present invention it is possible to prevente effectively from due to the rotating speed of vertical pivot 2 is too high and by the appearance of 1 burn observations of motor, more securely and reliably,
Instruction cost can be saved.
