The object of the invention to solve the technical problems realizes by the following technical solutions.According to micro-crack many multiples finder that the present invention proposes, include eyepiece, specimen holder, fixed bar, magnifier, base and light path pipe,
One end of described base is provided with fixed bar, is connected with light path pipe in the top movable of fixed bar, and the lower removable of fixed bar is connected with specimen holder, and the one end on described light path pipe top is provided with eyepiece, and one end of described light path pipe bottom is provided with magnifier;
The centre position of described light path pipe has notch, and light source is arranged on front or the diagonally forward of described notch correspondence position.
Further, aforesaid micro-crack many multiples finder, described eyepiece is socketed in the one end on described light path pipe top, and the bottom of described eyepiece and the upper edge of described notch are in same level or exceed the upper edge of described notch.
Further, aforesaid micro-crack many multiples finder, described magnifier is connected with light path pipe by the magnifier deck be arranged on bottom light path pipe.
Further, aforesaid micro-crack many multiples finder, described specimen holder is movably connected on described fixed bar by parbuckle screw, along described fixed bar height up and down.
Further, aforesaid micro-crack many multiples finder, the upper surface of described base is plane or groove, can size and dimension per sample for placing large-scale sample.
Further, aforesaid micro-crack many multiples finder, described notch is circular arc cutaway.
Further, aforesaid micro-crack many multiples finder, the circular arc cutaway major radius direction of described notch is consistent with the length direction of described light path pipe.
By technique scheme, micro-crack many multiples finder of the present invention at least has following advantages:
Micro-crack many multiples finder of the present invention arranges specimen holder and light path pipe by activity on fixed bar, can observe for the micro-crack of different sample, wherein specimen holder can regulate along the above-below direction of fixed bar, meets the observation requirement of different size sample; The centre position of light path pipe has notch, arranges light source, natural light or daylight lamp can be adopted directly to observe as light source in the front of notch according to needing of observing of crackle, without the need to arranging special light emitting source, and also can effective saving resource; And notch has certain optically focused effect, be conducive to obtaining better observations; Angle between light path pipe and fixed bar also can regulate as required, and according to different requirements, the multiple of magnifier can arbitrarily be changed, and meets the observation of different sample; Sample for big size can prevent the upper surface at base, and base upper surface can arbitrarily be set to plane or concave surface as requested.Micro-crack many multiples finder of the present invention can use different multiples magnifier to observe the micro-crack of metallic article, and workable, and crackle is observed clear, and each parts dismounting and change is convenient.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of instructions, be described in detail as follows below with preferred embodiment of the present invention.
