Clamping block and right clamping block are respectively provided with an inclined-plane and a vertical, under described bottom support plate
Surface offers transverse groove and cannelure, and the left side of described left clamping block offers bar-shaped trough
A, the right side opening of described right clamping block is provided with bar-shaped trough B, in the centre position of bottom support plate
Offering centre bore, the front surface at left clamping block, right clamping block is opened to its rear surface respectively
It is provided with through hole, and inwardly offers stress on the surface of described bar-shaped trough A, bar-shaped trough B and release
Discharge hole.
As optimal technical scheme of the present utility model, described transverse groove, cannelure, bar shaped
The cross section of groove A and bar-shaped trough B is rectangle.
As optimal technical scheme of the present utility model, described transverse groove, cannelure, bar shaped
Groove A is the most identical with the degree of depth of bar-shaped trough B.
As optimal technical scheme of the present utility model, described left clamping block, right clamping block are big
Little shape is identical, and described left clamping block, right clamping block become with bottom support plate integrated injection molding
Type.
As optimal technical scheme of the present utility model, described stress relief hole is blind hole.
Compared with prior art, the beneficial effects of the utility model are: this utility model is tied
Structure is simple, reasonable in design, is arranged by integrated injection molding, it is possible to reduce stress, improves
In its service life, it is provided by left clamping block and right clamping block, it is possible to square shaped test specimen enters
Row clamping, prevents test specimen from coming off.
