The lower wall of weight-hanger 6 is fixedly installed with round bar 14, and round bar 14 is placed in sleeve 13, and the present apparatus is by being placed in sleeve
Round bar 14 in 13, so that when after weight-hanger 6 places counterweight, when wire 5 can inevitably shake, so that and round bar
The weight-hangers 6 of 14 connections can not significantly double swerve so that chuck 7 can reply stable state faster, in turn
Reflective laser method is carried out as early as possible measures wire Young's modulus.
Specifically, in order to guarantee that mirror 11 can be tilted a certain angle, mirror support after wire 5 stretches
Device 10 includes support plate, and support plate is parallel to ground when being in original state, the direction of illumination alignment of laser emitter 12
The reflecting surface of mirror 11, the left and right sides lower wall of support plate are fixedly installed with triangular support block, left side triangular support block
Lower wall is bonded with the upper wall of chuck 7, and the lower wall of right side triangular support block is bonded with the upper wall of supporting table 8, a left side for right support 2
Side wall is equipped with scale line, and the zero point of scale line and the light launch point of laser emitter 12 are in sustained height.
Specifically, shaking and in order to make sleeve 13 that can limit 14 left and right directions of round bar because directly contact is justified
Bar 14 causes measurement result inaccurate, and the internal diameter of sleeve 13 is greater than the diameter 2mm of round bar 14.
Specifically, further including communicating pipe 16, the upper wall of left side auxiliary support plate 3 is fixedly installed with steel ladle 15, sleeve
13 pass through 16 connection of communicating pipe with steel ladle 15, due to there is also the rolling of vertical direction after weight-hanger 6 places counterweight
It is dynamic, by being filled the water to steel ladle 15, due to the effect of communicating pipe 16, so that also will be with same with steel ladle 15 in sleeve 13
The water of sample height, water in sleeve 13 due to buoyancy presence will abundant buffering 14 up and down direction of round bar shaking so that
Chuck 7 is faster in stable state, by the setting of steel ladle 15, achievees the effect that facilitate and fills the water into sleeve 13.
Specifically, may be impacted to the tensile elongation of wire 5, and then cause to survey due to the presence of buoyancy
The inaccurate problem of amount occurs, and the right side wall of steel ladle 15 is fixedly installed with outlet pipe 17, and outlet pipe 17 is equipped with valve, by going out
The water in steel ladle 15 and sleeve 13 can be discharged in water pipe 17, and the upper wall of auxiliary support plate 3 is equipped with and conveniently goes out in outlet pipe 17
The slot being filled with water at water.

Aerosol producer 19, aerosol producer 19 connect extraneous power supply, and the left side upper wall of placement plate 18 offers outlet flue 20, outlet flue
20 with the output end of aerosol producer 19 by 21 connection of pipeline, due to the presence of room light, student is difficult quickly in scale
Reading electricity is found on line, need to only open aerosol producer 19 at this time, smog will be just discharged downwards by outlet flue 20, since fourth reaches
That effect, the path of light is identified cracking, and then student judges that reflection light is radiated at scale line for cracking
Position.
Working principle: the utility model is a kind of experimental facility for measuring Young modulus of metal wire by stretching method, and when work opens
Laser emitter 12, light will be radiated at backtracking after mirror 11, add water in steel ladle 15 at this time, so that in sleeve 13
Full of water, the counterweight of requirement of experiment is placed on weight-hanger 6 at this time and is inevitably shaken after counterweight is placed, it is left
The shaking of right direction will be since limit effect of the sleeve 13 to round bar 14 will be substantially eliminated, while the shaking of vertical direction will be by water
Buoyancy offset so that chuck 7 replys stabilizations quickly, at this time by the discharge sleeve 13 of outlet pipe 17 in steel ladle 15
Water avoids buoyancy from impacting 5 deformation quantity of wire, at this time since the deformation chuck 7 of wire 5 will move down, so that
Mirror 11 tilts, and light will impinge upon on scale line by reflection, at this time due to the influence of indoor light, is radiated on scale line
Putting will be not easy to be identified by student, aerosol producer 19 need to only be opened at this time, since the path of Tyndall effect light will be abundant
It has been shown that, and then student is facilitated to find by the point of reflection on scale line, student records numerical value.
