Driving piston rod 913 drives first piston 912 to move and causes the first oil pocket 915 to flow to the second oil pocket 916, the oily flow direction quilt
Velocity sensor 96 detects that velocity sensor 96 controls 951 dead electricity of electromagnet, so that electromagnetic force is inhaled by control system
Conjunction mechanism 95 loses the fixation to first piston 912 and second piston 914（That is 914 energy of first piston 912 and second piston
It is enough to produce relative movement）, door-plate 942 pushed open when oil stream crosses intercommunicating pore 941 so that oil stream it is straight-through through intercommunicating pore 941 and into the
Two oil pockets 916（I.e. door-plate 942 does not produce damping action to oil）, it is achieved thereby that damping action is smaller without causing damping bullet
Spring contraction is obstructed namely spring can in time shrink and reduce spring contraction stroke and jolt, in door after spring contraction stroke
Under the action of sheet reset mechanism（I.e. since keep down inclination and density of door-plate is more than oil）And rotate and close automatically, door-plate 942
Again stop in intercommunicating pore 941.Then the elongation of damping spring 92 is resetted and released energy, and the result of elongation causes damping oil cylinder
Cylinder body 911 and first piston 912 produce disengaging movement and make it that the second oil pocket 916 reduces and the first oil pocket 915 becomes larger so that oil warp

First piston 912 and second piston 914 are fixed and are pressed on oil, during the oily direction runner door-plate 942 can not be open,
Allow oil to produce frictional damping phenomenon and energy-absorbing, in whole spring contraction stroke middle door-plate 942 so as to reducing spring elongation
Stroke jolts.
The damping energy-absorbing shock absorbing process of door-plate is：Oil stream is rocked and will shaken through main damp channel, branch damp channel and damper rod
Energy is changed into thermal energy and consumes.When being not enough to promote the blind hole deform if vibration is smaller, only oil rocks at this time,
Damper rod is produced and rocked and energy-absorbing when oil rocks.

It is interior.Coming directly towards driving mechanism 822 includes the first driving driving column 8222 of column 8221 and second.First driving column 8221 and second drives
Column is arranged in yaw 815, and stretches out the outer end face for only putting section 812.
Referring to Fig. 6, pendulum groove 814 has three, and accordingly yaw 815 also wants three.Three are put grooves 814 along only pendulum section 812
It is circumferentially distributed.Do not have to be designed with helix alignment's holding mechanism 82 between yaw and pendulum groove.Section 812 is only put according to square clockwise in figure
When abutting together to the side wall portion 8141 for turning to the same pendulum groove of yaw 815, another side of sidewall portion 8142 of yaw 815 and pendulum groove
Between produce swing gap 83, main paragraph 811 screw thread and only pendulum section 812 screw thread be located on same helix.
Referring to Fig. 7, top driving mechanism 822 further includes driving column fastening screw 8224, insertion spring 8223 and driving column
Depart from spring.Driving column fastening screw 8224 is in major diameter section 813 and is inserted into yaw 815.It is inserted into spring 8223
In major diameter section 813.
Referring to Fig. 1, Fig. 5, Fig. 6 and Fig. 7, when nut 8 is screwed on round end 43, the first drive rod 8221 is pressed, first drives
The driving of lever 8221 top 821 extend into by swinging in gap 83 and is connected on another side of sidewall portion 8142 of pendulum groove and puts
First 815 abut together and so that the screw thread of main paragraph 811 and the helix alignment for only putting section 812 with the side wall portion 8141 for putting groove
And on same helix, driving driving column fastening screw 8224 is inserted into first under the action of spring 8223 is inserted at this time
In driving column 8221, the first driving column 8221 is set to be maintained at current state（It will come directly towards and be connected on another side of sidewall portion of pendulum groove
Position state）.It is so that convenient and strength-saving during rotating nut.
When nut and round end 43 are screwed together, the driving column 8222, second of pressing second drives the driving driving column of column 8222
Fastening screw 8224 departs from the first driving column 8221, and driving column departs from spring driving the first driving column 8221 and ejects and lose to top
First 821 driving effect and driving column fastening screw 8224 can not be inserted into the first driving column 8221.Only put at this time
It can be relatively rotated between section 812 and main paragraph 811, it is vibrated and cause blind rivet to have the trend of disengaging with connection screw thread hole
When, only putting the rotation of section 812 and main paragraph 811 can cause the screw thread of the two to stagger, so as to prevent the generation of abjection.
Referring to Fig. 1, detection process of the invention is：Gauge outfit will be being verified to relative zero by standard workpiece.Then
The both ends of the step part to be measured 61 of the body of rod 6 are respectively rested on the first V-type stent 51 and the second V-type stent 52 and step 62
Drawn close with the first V-type stent 51, measurement bar 42 is in contact with measurement step end face 63, be after reading the number of degrees of gauge outfit 41
Measure a platform 61 length of step part to be measured.
Referring to Fig. 8, in table top during store things, article 54 is shelved on removable cover 3, is acted in the weight of article 54
Lower support board 32 declines and drives support spring 23 to shrink, under the directly extruding of article 54 or/and under the driving of support board 32
Gusset plate 33 is rotated down with hinge 37 for axis so that article 54 is encased in storing hole 55 and is limited, so that article 54
Will not slide in the horizontal direction and drop and the presence of gusset plate 33 so that support board and storing hole 55 wall portion between do not have
Big gap.Support board 32 is the driving realized by linkage mechanism 38 to gusset plate 33.After article 54 are removed, supporting
Support board 32 resets under the action of spring 23, when support board 32 resets on the downside of driving effect of the linkage mechanism 38 to gusset plate 33
Coaming plate 33 is also reset to horizontality.
When specular layer 35 needs replacing, remove bolt 36 and extract old specular layer 35 upwards and then according to upper new
Specular layer.
