Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under Face will combine the attached drawing in the utility model embodiment, be carried out to the technical scheme in the embodiment of the utility model clear, complete Ground describes.
Referring to Fig. 1-5, present embodiment is achieved using following technical scheme, it includes two and is symmetrical arranged Original position stretching machine worktable 2, fixed pedestal 15 is installed on the original position stretching machine worktable 2, the fixed pedestal 15 with it is in situ It is screwed on and is integrally fixed by stud between stretching machine worktable 2, the side of top surface is vertically installed on the fixed pedestal 15 Angle scale 1 is equipped with interfaced bar specimen holder or sheet coupon fixture in the angle scale 1;
The generally disc-shaped structure of angle scale 1, the angle scale 1 middle part perforation open up there are one fixture rotate Hole 14 is etched with corresponding angle value at the periphery of the angle scale 1.
The sheet coupon fixture include upper fixture 3 and with the symmetrically arranged lower fixture 4 of upper fixture 3, upper fixture 3 under By being integrally fixed with positioning pin 8 and stud between fixture 4, the upper fixture 3 on lower fixture 4 respectively perforation offer Can be with the holder pin hole 7 of 8 clearance sliding fit of positioning pin, the both ends of the positioning pin 8 are respectively arranged with can be with its interference The positioning rubber set 9 of socket cooperation;
