A first threaded rod 201 is rotatably connected to one side of the interior of the fixed box 2, and a first slide rod 203 is fixedly installed on the other side of the interior of the fixed box 2. Multiple clamping plates 204 are threadedly connected to the outer surface of the first threaded rod 201. The multiple clamping plates 204 are arranged at equal intervals and are slidably connected to the first slide rod 203. When the user rotates the first threaded rod 201, the multiple clamping plates 204 will move simultaneously.

[0023] Multiple auxiliary plates 205 are fixedly installed at the opening on the outer surface of the fixing box 2, and the multiple auxiliary plates 205 and multiple clamping plates 204 are arranged in a cross pattern. Multiple spandex threads are placed between the multiple clamping plates 204 and the multiple auxiliary plates 205 in sequence. Then, the first threaded rod 201 is rotated, so that the multiple clamping plates 204 move simultaneously toward one side of the auxiliary plates 205 to clamp and fix the multiple spandex threads. A first rotating handle 202 is fixedly installed at one end of the first threaded rod 201 that extends to the outside of the fixing box 2. The user can rotate the first threaded rod 201 by holding and rotating it.

[0024] A base 3 is fixedly installed on the outer surface of the test frame 1 at the middle of one side of the fixed box 2. The base 3 is located between the two fixed boxes 2, and two guide rods 301 are fixedly installed on one side of the base 3. A fixing plate 304 is fixedly installed on the end of the two guide rods 301 away from the base 3. Two springs 303 are fixedly installed on the fixing plate 304 on one side of the two guide rods 301. The two guide rods 301 pass through the interior of the two springs 303 respectively. A fastening plate 302 is slidably connected to the outer surface of the two guide rods 301. The fastening plate 302 can move along the two guide rods 301.

[0025] Both springs 303 are fixedly connected to the fastening plate 302. When the fastening plate 302 moves along the two guide rods 301 toward one side of the fixed plate 304, it will compress the springs 303.

[0026] A pull rod 305 is fixedly installed on the side of the fastening plate 302 near the fixing plate 304, and the pull rod 305 is slidably connected to the fixing plate 304. A handle 306 is fixedly installed on the end of the pull rod 305 away from the fastening plate 302. The user can pull the pull rod 305 by holding the handle 306, so as to move the fastening plate 302.

[0027] The test frame 1 has lifting slots 101 at both the top and bottom of one side of the fixed box 2. A second threaded rod 102 is rotatably connected to one side of the interior of each lifting slot 101, and a second slide rod 103 is fixedly installed on the other side of the interior of each lifting slot 101. A connecting block 105 is threadedly connected to the outer surface of each of the two second threaded rods 102, and the two connecting blocks 105 are slidably connected to the two second slide rods 103 respectively. The two connecting blocks 105 are fixedly connected to the two fixed boxes 2 respectively. By rotating the second threaded rod 102, the connecting block 105 can move along the second slide rod 103. When the connecting block 105 moves, it can drive the fixed box 2 to move, thereby adjusting the position of the two fixed boxes 2.

[0028] The outer surfaces of the two lifting slots 101 are rotatably connected to the second rotating handles 104, and the two second rotating handles 104 are respectively fixedly connected to the two second threaded rods 102. The user can rotate the second threaded rods 102 by holding and rotating the second rotating handles 104.

[0029] The outer surface of the test frame 1 has movable slots 1011 on both the left and right sides of one side of the fixed box 2. The two movable slots 1011 are fixedly installed with fixed rods 1012. The outer surfaces of the two fixed rods 1012 are slidably connected to two cutting frames 1013. The two cutting frames 1013 can move along the two fixed rods 1012 to adjust their positions. The two cutting frames 1013 are hinged with blades 1014 on one side. By rotating the blades 1014, multiple spandex threads can be cut and sampled.

[0030] Multiple positioning holes 1015 are provided on one side of the outer surface of each of the two movable slots 1011. A scale 1016 is fixedly installed on the outer surface of the test frame 1 on the left side of one side of the cutting frame 1013. The scale 1016 allows the user to visually observe the distance between the two cutting frames 1013. Connection holes 1017 are provided on the left and right sides of the outer surface of the two cutting frames 1013. When the cutting frame 1013 moves along the fixed rod 1012, the connection hole 1017 will coincide with the multiple positioning holes 1015 in sequence. By inserting the bolt into the coincided connection hole 1017 and positioning hole 1015, the moved cutting frame 1013 can be fixed.

[0031] The working principle of this utility model is as follows: First, pull the handle 306 to move the fastening plate 302 towards one side of the fixing plate 304. Then, place multiple spandex threads between multiple clamping plates 204 and multiple auxiliary plates 205. Rotate the first threaded rod 201 to move the multiple clamping plates 204 simultaneously towards the auxiliary plates 205, thus clamping and fixing one end of the multiple spandex threads. Then, pass the other end of the multiple spandex threads through the fastening plate 302 and the base 3, and repeat the above clamping steps. The other ends of multiple spandex threads are clamped and fixed, thereby applying pretension to the spandex threads. Then the pull handle 306 can be released, and the compressed spring 303 can push the fastening plate 302 to reset, so as to clamp the middle of multiple spandex threads. Then, after the spandex threads are subjected to the corresponding pretension and wait for about 20 seconds, the two cutting frames 1013 are moved so that the distance between the two blades 1014 is 1000mm, and the two blades 1014 are rotated, so that multiple clamped spandex threads can be cut and sampled at the same time.
