Specific embodiment
It is as follows that the present invention is described further with reference to the accompanying drawings and examples:
A kind of gleeble loading instrument, as shown in Figure 1, Figure 2 and Figure 3, including two handgrips 1, described handgrip 1 includes pressing from both sides
Hold portion 11, connecting portion 12 and Handheld Division 13, described connecting portion 12 one end is connected with Handheld Division 13, the other end is with clamping part 11 even
Connect；
Semicircle groove 111 is provided with described clamping part 11, the semicircle on the connecting portion 12 of described two handgrips 1 is led to
Groove 111 opening surrounds sample installing hole relatively；It is equipped with semicircular first step groove 112 and second at the two ends of clamping part 11
Step groove 113；Described first step groove 112 and second step groove 113 are coaxial with groove 111, and, the half of first step groove 112
Footpath is more than the radius of groove 111, and the radius of second step groove 113 is more than or equal to the radius of first step groove 112；Described two
First step groove 112 opening on the connecting portion 12 of individual handgrip 1 surrounds tantalum piece installing hole relatively；The connection of described two handgrips 1
Second step groove 113 opening in portion 12 surrounds graphite flake installing hole relatively；Described tantalum piece installing hole and graphite flake installing hole with
Sample installing hole is connected；And, tantalum piece mounting hole site is between graphite flake installing hole and sample installing hole；Clamping part 11 sets
Have along the circumferentially disposed thermocouple groove of clamping part 11 114, described thermocouple groove 114 is by sample installing hole along sample installing hole radially
Run through the outer surface of clamping part 11；
The connecting portion 12 of described two handgrips 1 is flexibly connected, and is provided with clamping two between the connecting portion 12 of two handgrips 1
