Between and supported by first cam and the second cam, with the rotation of first cam and the second cam, the transmitting of laser emitter
Irregular rotation is done with the irregular contour of first cam and the second cam in end, so that the rotation by irregular cam makes
It is mobile by specified path to obtain laser emitter, projects designated shape.
The utility model may be implemented to project the function of customized laser pattern, and on the other hand, the utility model both included
Have the electromechanical knowledge of gear drive, cam drive and laser projection, attract student attention simultaneously, both develop student's
Intelligence, and improve the learning interest of student；In addition the outer circular shape of cam can the shape that projected according to laser emitter
Then design is come out using 3D printing, cam commutativity is strong, at low cost, is very suitable for intelligence development teaching.
As a kind of improvement of the utility model, the fixed bracket is equipped in the installation end corresponding position with laser emitter
V-type fork, the installation end of the laser emitter are placed on V-type fork.
As a kind of improvement of the utility model, the transmission ratio between first cam, the second cam and driving gear is equal
For 5:1.
Further, the laser emitter is the green laser emitter that wavelength is 535RM.
Compared with prior art, the utility model has the advantage that
The utility model may be implemented to project the function of customized laser pattern, and on the other hand, the utility model both included
Have the electromechanical knowledge of gear drive, cam drive and laser projection, attract student attention simultaneously, both develop student's
Intelligence, and improve the learning interest of student；In addition the outer circular shape of cam can the shape that projected according to laser emitter
Then design is come out using 3D printing, cam commutativity is strong, at low cost, is very suitable for intelligence development teaching.
