Specific embodiment
Below based on embodiment, present invention is described, but the present invention is not restricted to these embodiments.Under
Text to the present invention datail description in, it is detailed to describe some specific detail sections.Do not have for a person skilled in the art
The description of these detail sections can also understand the present invention completely.In order to avoid obscuring the essence of the present invention, well known structure, side
There is no narrations in detail for method.
Support frame positioning device in the present embodiment, it is shown in Figure 1, including the first clamping piece 1, the second clamping piece 2 and branch
Frame 6.Stent 6 is arranged between two clamping pieces, between clamping piece and stent by elastic positioning device and with flexibly positioned dress
Put matched locating slot positioning.
Preferably, stent 6 is the advanced scientific research such as scanning tunneling microscope (STM), angle resolved photoelectron spectroscope instrument (ARPES)
Instrument would generally use specimen holder, for the sample measured needed for fixation.Sample is arranged on the front of specimen holder, flexibly positioned dress
It puts and is arranged between the back side of specimen holder and clamping piece, referring to Fig. 3.
In the present embodiment, elastic positioning device is filled using elastic device and positioning ball 4, in the present embodiment elasticity
It puts using shrapnel 3, wherein shrapnel is arranged on the first clamping piece, and positioning ball is connected by shrapnel with the first clamping piece.
The quantity for positioning ball is at least two, preferably 3, can realize accurate and reliable positioning, prevent specimen holder relative to folder
Hold piece movement.The structure that multiple positioning balls share one may be used in shrapnel, and as shown in this embodiment, shrapnel 3 is rectangular
Frame shape, three positioning ball layouts are on the shrapnel of frame shape；In addition to this, it can also use each positioning ball that one elastic piece is set
Structure.In addition to shrapnel, elastic component can also use spring or other elastic constructions and combination thereof.
Part is connected through a screw thread between two clamping pieces to be connected, and can be adjusted between clamping piece by adjusting threaded connector
Clamping force, the relative position between shrapnel and the first clamping piece can also be adjusted, and then adjust shrapnel to positioning ball and sample
The elastic force of product frame, the final dual purpose for realizing specimen holder positioning and clamping.Shrapnel may be used fixed mode and be arranged on folder
On piece is held, can also be arranged on clamping piece by the way of position-adjustable, so as to adjust specimen holder and clamping piece
Relative position.
Preferably, orientation room's (not shown) is equipped on clamping piece, shrapnel and positioning ball are arranged in orientation room, fixed
Position room is equipped with opening in face of specimen holder side, and the opening width is less than the diameter of positioning ball, can prevent positioning ball from orientation room
Abjection, positioning ball at least part is exposed to be used to match with the spherical groove of specimen holder in the outside of orientation room.Shrapnel is used for
Elastic force is applied to the direction for being exposed to orientation room's opening to positioning ball.It can respectively be set for each positioning ball independent
Whole positioning balls can also be arranged in an orientation room by orientation room.Orientation room can be provided projectingly from clamping piece；
The inside of clamping piece can be embedded into, keep the smooth of clamping piece surface, at this time from outside, only position a part for ball
Protrude from the surface of clamping piece, in this way can clamping piece accommodate specimen holder when, reduce protrusion caused by interference, clamping it is more accurate
It is really and firm.
With the corresponding position of positioning ball arrangement position on specimen holder, equipped with multiple locating slots, it is in the present embodiment
Spherical groove 5, referring to Fig. 2, the profile of spherical groove matches with positioning the surface shape of ball.When specimen holder is fixed to clamping piece
When middle, specimen holder pushes positioning ball, positioning ball compression shrapnel, when sample rack moving is to correct position, in the elastic force of shrapnel
Under effect, positioning ball insertion spherical groove is interior and then realizes the accurate positionin of specimen holder.
Further, it is also possible to using shrapnel and positioning ball being arranged on specimen holder, spherical groove is arranged on some clamping piece
On mode, can also realize the accurate positionin of specimen holder.Preferably, aforementioned orientation room is arranged on specimen holder to accommodate
Position ball and elastic component.
In addition, positioning ball can be used conductive material and be made, used as electrode, specimen holder, which is adopted, to be made from an insulative material, fixed
Position ball one end passes through specimen holder and sample phase by 8 connecting test instrument (not shown) of conducting wire, the other end by conducting wire 9
Even, it as shown in figure 3, in this way after sample grows up to, does not need to take out sample from specimen holder, directly passes through support frame positioning device
It can be realized the measurement to sample, measure more convenient while nor affect on accurate positionin to sample.
In addition, locating slot can also use the structure of elongated slot, preferably straight-line groove, arc groove or combination thereof, slot two
Side wall and being formed to positioning ball for elastic component limit, it is achieved thereby that the positioning to positioning two dimensions of ball so that positioning ball quilt
It is limited to move along elongated slot, in order to adjust the relative position of specimen holder and clamping piece.
