In order to further improve clamping steadiness of second fixture block 3 to test specimen, it is provided with second on second fixture block 3 and wears
Hole, when the first groove 21 and the second groove 31 clamp test specimen, connector 6 through described second perforation be connected with base thread and
Second fixture block 3 is fixed on pedestal.After the second fixture block of top pressure 3 of nut 42 is twisted, can further pass through connector 6 by this position
The second fixture block 3 put is fixed on pedestal, prevents from the second fixture block 3 occur when nut 42 occurs and loosening to slide and cause test specimen
The situation of loosening, and then cause result of the test inaccurate, the characteristics of safe and reliable and accurate with guarantee test.
The groove 31 of first groove 21 and second is " V " type structure.Due to test specimen be cylindrical structural, the first groove 21
And second the clip slot 5 formed between groove 31 in clamping test pieces, clip slot 5 forms the clamping structure for contacting on four sides with test specimen.Should
The clip slot 5 of structure is cuniform increase power structure, can increase pressure on top surface of the clip slot 5 to test specimen, improves the clamping steadiness to test specimen.When
So, first groove 21 and the second groove 31 of other structures shape is also adapted to the present invention.
The base 1, the first fixture block 2 and the second fixture block 3 are ferrous materials.Can be by the He of base 1 by the way of welding
First fixture block 2 is welded together, and manufacture is quick, and need not carry out pouring maintenance, has saved substantial amounts of manufacturing time and material.
Embodiment 2
The present embodiment be on the basis of embodiment 1, it is described as the improvement to fit structure between guide groove 11 and guide block
Base 1 is provided with guide rail, and the bottom surface of second fixture block 3 is provided with slide block, the slide block be slidably sheathed on the guide rail and
Second fixture block 3 is slidably mounted on the base 1.There is less friction using the sliding connection of slide block and guide rail
Power, reduces the resistance of the slip of the second fixture block 3, improves the slip fluency of the second fixture block 3, can prevent discontinuity slip
Situation occurs, it is ensured that the active force of 42 pairs of the second fixture blocks 3 of nut can be applied on test specimen completely by the second fixture block 3, improves folder
The steadiness held.
Above disclosed is only a kind of preferred embodiment of the invention, can not limit the power of the present invention with this certainly
Sharp scope, therefore the equivalent variations made according to the claims in the present invention, still belong to the scope that the present invention is covered.
