The front side of the right part of the connecting frame 1 is connected with a first motor 2. The output shaft of the first motor 2 is connected with a first double lead screw 3. The first double lead screw 3 is rotatably connected with the connecting frame 1. Both the front and rear parts of the first double lead screw 3 are threadedly connected with a first moving frame 4. The first moving frames 4 are both slidably connected with the connecting frame 1. The left part of the front first moving frame 4 is connected with a second motor 7. The output shaft of the second motor 7 is connected with a second double lead screw 8. The second double lead screw 8 is rotatably connected with the front first moving frame 4. Both the left and right parts of the second double lead screw 8 are threadedly connected with a telescopic plate 9. The telescopic plates 9 are both slidably connected with the rear first moving frame 4. Both the first moving frame 4 and the upper side of the middle part of the telescopic plate 9 are connected with a fixed frame 5. The frontmost and rearmost fixed frames 5 are both threadedly connected with a first screw 6. The lower sides of the first screws 6 are both rotatably provided with a first clamping plate. The first clamping plates are both slidably connected with the adjacent fixed frame 5. The leftmost and rightmost fixed frames 5 are both threadedly connected with a second screw 10. The lower sides of the second screws 10 are both rotatably provided with a second clamping plate. The second clamping plates are both slidably connected with the adjacent fixed frame 5. The rear part of the connecting frame 1 is slidably connected with a second moving frame 11. The upper side of the middle part of the second moving frame 11 is connected with a third motor 12. A connecting piece is provided on the output shaft of the third motor 12. A guide post 13 is slidably connected to the connecting piece. A spring 14 is connected between the guide post 13 and the connecting piece. The right side of the front part of the connecting frame 1 is connected with a fourth motor 15. The output shaft of the fourth motor 15 is connected with a connecting screw 16. The connecting screw 16 is rotatably connected with the connecting frame 1. A scraper 17 is threadedly connected to the connecting screw 16. The scraper 17 contacts the connecting frame 1.

[0020] At this time, the spring 14 is in a contracted state. When using this device, first place the connecting frame 1 in the experimental area of the shape memory body, then place the shape memory body between the fixing frames 5, and then rotate the first screw rod 6 and the second screw rod 10, so that the first screw rod 6 and the second screw rod 10 move downward under the action of the thread, making the first clamping plate and the second clamping plate contact the shape memory body. Then, externally connect a cold air device through the connecting pipe 18, so that cold air is ejected from the nozzle holder 19. Then start the first motor 2 to drive the first bidirectional lead screw 3 to rotate, driving the first moving frame 4 to move under the action of the thread, making the first moving frames 4 move away from each other, so that the shape memory body is stretched in the front-back direction.

Then rotate the first screw rod 6 and the second screw rod 10, so that the first screw rod 6 and the second screw rod 10 move upward under the action of the thread, making the first clamping plate and the second clamping plate no longer contact the shape memory body, so that the deformed shape memory body falls on the connecting frame 1. Then take out the cold air device, and then connect a hot air device through the connecting pipe 18, so that the hot air touches and ejects through the nozzle holder 19. Then observe the recovery situation of the shape memory body. After the detection is completed, start the fourth motor 15 to drive the connecting lead screw 16 to rotate, so that the scraper 17 moves under the action of the thread, so that the shape memory body that has been detected is pushed out, so that the shape memory body can be automatically pushed out, with simple operation, which is convenient for experimenting on the next shape memory body and improves work efficiency.
