Further, the counterweight is breach counterweight.
Further, the front pressuring plate and the stepped matching of the rear fender, breach is provided with the matching.
Further, the front pressuring plate and the rear fender are provided with right-angled intersection projection with clamping sample contacts part.
Further, the baking oven is additionally provided with observation window.
The beneficial effects of the utility model：（1）By setting spring between rear fender surface and screw, spring has certainly
Dynamic Telescopic, sample temperature distortion, can also keep pressing plate not loosen, and realization device can adapt to the examination of different size thickness sample
Test, sample temperature distortion is not fallen off；（2）By setting right-angled intersection raised in clamping sample parts, increase retained part has
Frictional force is imitated, is not easy to slide；（3）It is replaceable more convenient using breach counterweight；（4）Watch window is set up, can be more intuitively
Observation test, avoid opening baking oven observation influence test effect.

Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " on ", " under ",
The orientation or position relationship of the instruction such as "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " are
Based on orientation shown in the drawings or position relationship, it is for only for ease of description the utility model and simplifies description, rather than instruction
Or imply that signified device or element must have specific orientation, with specific azimuth configuration and operation, therefore be not understood that
For to limitation of the present utility model.
As shown in Figure 1, Figure 2 and shown in Fig. 3, a kind of hot extending test device, including baking oven 1, the baking oven 1 is interior to be fixedly mounted
There is test bracket 5, the test bracket 5, which is provided with, stretches rate chi 4 and clamping device 2, and the upper end of rate chi 4 of stretching is fixed in vertical state
On the test bracket 5, the test bracket 5 is provided with through hole for holding；The clamping device 2 includes front pressuring plate 202 with after
Pressing plate 203, the front pressuring plate 202 and rear fender 203 are fixed on the test bracket 5 using screw 209 by the through hole,
Tightened using wing nut 201, spring 208 is provided with the screw 209, rear fender 203 described in the end thereof contacts of spring 208
Surface, the head end of screw 209 described in another end in contact, because spring 208 has an automatic telescopic function, the temperature distortion of sample 3,
Also clamping device 2 can be kept not loosen, realization device can adapt to different size thickness specimen test, and sample temperature distortion does not take off
Fall；The experimental rig is also equipped with device of raising the price, and the device of raising the price includes hook, counterweight bar 6, holds yard platform 8 and counterweight 7；It is described
Counterweight 7 is breach counterweight, more convenient when changing or raising the price, if counterweight 7 places at least two, is handed over using opposed notches
Fork is placed, and prevents counterweight 7 not at center, can still keep stable；The front pressuring plate 202 and the rear fender 203 are in rank
Scalariform matches, and 204 are provided with breach 205 at the matching；The front pressuring plate 202 and the rear fender 203 and clamping sample contacts portion
