The front side of shape baffle.
When needing to demonstrate anaclasis, laser pen is first put between two briquettings with hand by teacher, and to moving to left
Dynamic laser pen is moved to the left briquetting, and briquetting, which is moved to the left, is moved to the left circular slab, and No.1 spring compresses therewith, subsequent teacher
Rotation laser pen makes to rotate the left side that fixture block is located at fixed fixture block, and then teacher unclamps laser pen, in the work of No.1 spring force
Under rotation fixture block can be close to fixed fixture block, laser pen can be so fixed, teacher uses and descends shift(ing) ring on hand
Shape sliding block, ring slider, which moves up and down, so that laser pen is moved up and down, and stop after laser pen is moved up and down to suitable position
Mobile, subsequent teacher, which opens laser pen, makes laser irradiation in semicircle glass, can be rolled over to laser by semicircle glass
It penetrates, in this way, light of the student, that is, observable after semicircle glass refraction understands anaclasis.After the completion of anaclasis demonstration, always
Teacher closes laser pen, and teacher, which rotates laser pen, separates rotation fixture block with fixed fixture block, so can be in No.1 spring force
Laser pen is set to move right under effect, subsequent teacher removes laser pen.
Teacher is moved to the left arc pressuring plate with hand, and No. two springs compress therewith, subsequent teacher with moving down movable pendulum motion block on hand,
Swinging block moves up and down ring slider up and down through oscillating rod, can so carry out to the angle of laser pen laser irradiation
It adjusts, after laser pen is moved up and down to suitable position, then unclamps arc pressuring plate, it can under the action of No. two spring forces
So that arc pressuring plate is moved right reset, swinging block can be so fixed, from sliding to annular always with hand without teacher
Block is fixed, and then can reduce the workload of teacher.
Teacher, which swings backward connecting rod with hand, swings backward support rod, and support rod is swung backward through elastic ball and ground
Contact, so can be supported fixation to the present invention by support rod, from using hand steered the present invention always without teacher, into
And the hand of teacher can be liberated, it can so facilitate teacher to go out the principle of anaclasis with finger, so as to roll over student to light
The knowledge penetrated becomes more apparent upon, and after the completion of anaclasis demonstration, with hand, swinging support bar resets teacher forward.
When needing to be shown anaclasis to student, curved baffle is put into two front side placing grooves up and down by teacher,
Inserted link is inserted into two guide sleeves up and down by subsequent teacher, and so curved baffle can be fixed, so as to by laser pen
The laser irradiated blocks, and then can prevent laser irradiation on the eyes of student, can so prevent the eyes to student
It damages, after the completion of anaclasis demonstration, teacher is taken out inserted link with hand out of guide sleeve, then puts curved baffle from front side
It sets in slot and takes out.
By the present invention in that rotation fixture block is close to laser pen can be fixed with fixed fixture block, opening laser pen makes to swash
Light is radiated at semicircle glass, can be reflected to laser by semicircle glass, can make arc pressure by No. two springs
Plate, which moves right, is fixed swinging block, and support rod, which is swung backward, can carry out the present invention by elastic ball and ground face contact
Support is fixed, and so as to reduce the workload of teacher, the laser that curved baffle can irradiate laser pen is blocked, Jin Erneng
It enough prevents laser irradiation on the eyes of student, can so prevent from damaging the eyes of student.
