Detailed description of the invention
Below, embodiment of the present utility model will be described with reference to the accompanying drawings.In embodiments, the part of same configuration uses identical Reference numeral and omits and describes.
Consult Fig. 1, for the utility model FRP compresses the combining structure schematic diagram of sample strain gauge adhesion chalker; And Fig. 6, the combining structure schematic diagram at another visual angle of sample strain gauge adhesion chalker is compressed for the utility model FRP.As shown in FIG., described chalker comprises T-shaped rule and the outer moveable positioning sliding block of described T-shaped rule.
Positioning sliding block 1 shown in composition graphs 2 to Fig. 4, and the T-shaped rule 2 shown in Fig. 5, known, described positioning sliding block 1 comprises a slide 5, laterally run through in described slide 5 and offer a Vacancy 6, and the side described slide 5 being offered Vacancy 6 is symmetrically arranged with upper and lower two line positions 7, described slide 5 upper end is also longitudinally run through and is provided with a duct 8 communicated with described Vacancy 6, be provided with internal thread in described duct 8, can wear into securing members such as screw, bolt, screws with the sample 3 placed in fixing described Vacancy 6.
