Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the embodiment of the present invention, when testing the tensile properties of clothing fabrics, the fixing plate 106 is toggled on the inner side of the guide slide 103 so that the fixing cone on the side of the fixing plate 106 leaves one end of the fixing groove 105, and the two ends of the fabric to be tested are respectively passed through the fixing grooves 105 on the upper and lower guide slides 103 and placed on the side of the guide slide 103. Under the action of the return spring, the fixing plate 106 performs preliminary positioning and fixing on one end of the fabric. After the fabric droops naturally, the upper traction plate 104 pulls the support plate 1010 upward along the grooves on both sides of the interior of the positioning bracket 102, and the support plate 1010 pulls the flip side plate 109 to rotate, and the flip side plate 109 drives the flip pressure plate 108 to rotate inside the movable slot 107 , the flip pressing plate 108 presses the other side of the fixed plate 106, so that the fixed plate 106 further fixes the upper end of the fabric. After the fabric is pulled upward and the traction plate 104 below is fixed, the fabric moves upward and drives the guide slide 103 to move upward, then the support plate 1010 below causes the flip side plate 109 to pull the flip pressing plate 108 to apply pressure to the fixed plate 106 below to fix the fabric. The greater the stretching amplitude of the fabric, the greater the fixing force of the fabric to prevent it from falling off. The rotating carrier plate 1 is rotated on the top of the fixed platform 101 to drive the four positioning brackets 102 to move to fix the fabric. The tensile test of the fabric at four locations can be performed at the same time, and the sampled fabric can be tested under the same environment to ensure the accuracy of the test data.

[0039] Embodiment 2, on the basis of embodiment 1, a column 2 is installed in the middle position of the top of the rotating carrier plate 1; a guide vertical rod 201 is installed on the top of the column 2; a guide groove 202 is provided on the side of the column 2; the guide groove 202 is connected to the inside of the column 2, and a driving cylinder is installed at the bottom end of the inner part of the column 2, a spring is installed on the inner side of the column 2, and a fixed push plate 203 is installed on the inner side of the column 2 through the spring, wherein the top of the fixed push plate 203 is provided with an inclined structure; a guide plate 204 is slidably installed on the inner side of the column 2; the guide plate 204 is on the outside of the fixed push plate 203, and the guide plate 204 is an arc structure, and a lower traction rod 205 is installed on the outside of the guide plate 204; the lower traction rod 205 is slidably installed inside the guide groove 202, and the outer end of the lower traction rod 205 is connected to the other side of the traction plate 104 below; the driving cylinder at the bottom end of the inner part of the column 2 A fixed slider 206 is installed on the output end; the fixed slider 206 is a circular structure, and the fixed slider 206 is slidably installed on the inner side of the fixed push plate 203; a driving cylinder is installed on one side of the top of the column 2, and a movable plate 207 is installed on the output end of the driving cylinder; the movable plate 207 is slidably installed on the outer side of the guide vertical rod 201, and an upper traction rod 208 is installed on the outer side of the movable plate 207; the side end of the upper traction rod 208 is connected to the other side of the upper traction plate 104; a circulation pipe 209, a refrigeration component 2010 and a heating component 2011 are installed on the top of the rotating carrier plate 1; the circulation pipe 209 is an annular structure, and the circulation pipe 209 is on the outer side of the column 2; control valves are installed on the output ends of the refrigeration component 2010 and the heating component 2011, and the output ends of the refrigeration component 2010 and the heating component 2011 are connected to the circulation pipe 209;The top of the circulation pipe 209 is provided with a guide vertical pipe 2012, wherein the side of the guide vertical pipe 2012 is provided with a slot. When the stretch performance of the clothing fabric is tested, the lower end of the fabric is fixed and naturally droops, then the traction plate 104 below drives the lower traction rod 205 to move downward along the guide groove 202, and the inner end of the lower traction rod 205 drives the guide plate 204 to move inside the column 2. After the fabric at four places droops, it drives the guide plate 204 to be at a relatively stable height, so that the fabric at four places is at the same initial slack. The driving cylinder at the bottom end of the column 2 drives the fixed slider 206 to move downward, and the side of the fixed slider 206 pushes the fixed push plate 203 to move. After the fixed push plate 203 moves outward, the position of the guide plate 204 is fixed, thereby positioning the lower end position of the fabric, and the upper traction rod 208 outside the movable plate 207 drives the fabric at four places to be at the same height, then the driving cylinder on the top side of the column 2 The movable cylinder drives the movable plate 207 upward along the guide vertical rod 201. The movable plate 207 drives the upper end of the fabric through the upper traction rod 208 to perform stretch testing. The refrigeration assembly 2010 or the heating assembly 2011 on the top of the rotating carrier plate 1 is activated. When the refrigeration assembly 2010 generates a cold airflow, the heating assembly 2011 stops operating. The cold airflow flows out through the slots on the side of the guide vertical pipe 2012 above the circulation tube 209, cooling the stretched fabric and allowing the fabric to be subjected to stretch testing in a relatively cold environment. Alternatively, when the heating assembly 2011 generates a hot airflow, the refrigeration assembly 2010 stops operating. The hot airflow flows out through the slots on the side of the guide vertical pipe 2012 above the circulation tube 209, heating the stretched fabric and allowing the fabric to be subjected to stretch testing in a relatively hot environment. This allows the fabric to be tested in different environments, ensuring comprehensive fabric stretch testing.

[0040] The third embodiment, on the basis of the first embodiment, a collecting hood 3 is installed on the outside of the fixed platform 101; an operating panel is installed on the outside of the collecting hood 3, and a collecting box 301 is also installed on the outside of the collecting hood 3; an air suction pump is provided on the side of the collecting box 301, and a collecting pipe 302 is installed on the input end of the air suction pump; the collecting pipe 302 is an annular structure, and the collecting pipe 302 is located on the outside of the bottom of the collecting hood 3, and the side of the collecting pipe 302 is connected to the side of the collecting pipe 303; the connecting pipe 303 is installed on the side of the collecting hood 3; an air pump is installed on the top of the collecting box 301, and a guide pipe 304 is installed on the output end of the air pump; a rotating plate 305 is rotatably installed on the top of the guide vertical rod 201; a plurality of evenly distributed connecting rods 306 are installed on the side of the rotating plate 305; an injection pipe 307 is installed on the side end of the connecting rod 306; the injection pipe 307 is an annular structure, and the side of the injection pipe 307 is connected to the top of the guide pipe 304, and the injection pipe 307 The bottom of the rotating plate 305 is provided with an air jet slot 308. When the tensile performance of the clothing fabric is tested, when the fabric is stretched and broken, the air pump on the top of the collecting box 301 starts working, and the air flow generated by the air pump enters the interior of the two air jet pipes 307 through the guide pipe 304. When the rotating carrier plate 1 rotates, it drives the guide vertical rod 201 to rotate at the bottom of the rotating plate 305. The rotating plate 305 positions the air jet pipe 307 through the connecting rod 306, so that the air jet from the air jet slot 308 at the bottom of the air jet pipe 307 blows and cleans the debris and thread ends floating in the process of fabric breaking, and the debris flows to the inside of the collecting cover 3, and the collecting pump on the side of the collecting box 301 works. The collecting cover 3 absorbs the air flow and carries the debris downward, and the air flow flows to the inside of the collecting box 301 through the connecting pipe 303 and the collecting pipe 302, preventing the thread ends and debris caused by the stretching and breaking of the fabric from floating to other places, ensuring the cleanliness of the testing environment, and reducing the workload of cleaning in the later stage.

[0041] The working principle of this embodiment is as follows: when in use, the two ends of the cloth to be inspected are respectively passed through the upper and lower fixed grooves 105 and placed on the side of the guide slide 103. Under the action of the return spring, the fixed plate 106 performs a preliminary fixation on one end of the cloth. When the cloth droops naturally, the traction plate 104 below drives the guide plate 204 at the inner end of the lower traction rod 205 to move inside the column 2. After the cloth droops on all sides, the guide plate 204 is in a relatively stable position. The driving cylinder at the bottom end of the column 2 drives the fixed slider 206 to push the fixed push plate 203 to move and fix the guide plate 204. The upper traction rod 208 on the outside of the movable plate 207 drives the fabrics at the same height at all four sides. The driving cylinder on the top side of the column 2 drives the movable plate 207 to move upward along the guide vertical rod 201. The movable plate 207 drives the upper end of the fabric to be stretched through the upper traction rod 208. The upper traction rod 208 drives the upper traction plate 104 to pull the flip side plate 109 through the support plate 1010 to rotate so that the flip pressing plate 108 presses the other side of the fixed plate 106. The upper end of the fabric is further fixed. After the fabric is pulled upward, the position of the lower traction plate 104 is fixed, and the lower support plate 101 After the movement, the flip side plate 109 pulls the flip pressure plate 108 to apply pressure to the fixed plate 106 below to fix the fabric. The greater the stretching amplitude of the fabric, the greater the fixing force on the fabric. At the same time, the fabric is stretched in four directions. The refrigeration component 2010 generates a cold air flow that flows out through the slots on the side of the guide vertical pipe 2012 above the circulation pipe 209. The fabric can be placed in a relatively cold environment for stretching testing. Alternatively, the heating component 2011 generates a hot air flow that flows out through the slots on the side of the guide vertical pipe 2012 above the circulation pipe 209. The fabric can be placed in a relatively hot environment. To carry out stretching testing, the fabric is placed in different environments for testing. The airflow generated by the air pump on the top of the collection box 301 enters the two jet pipes 307 through the guide pipe 304 and is ejected through the jet slot 308 to blow the floating debris and thread ends during the fabric breakage process downward into the collection cover 3. The collection pump on the side of the collection box 301 works, and the collection cover 3 absorbs the airflow and carries the debris downward. The airflow flows through the connecting pipe 303 and the collection pipe 302 to the inside of the collection box 301, preventing the thread ends and debris caused by the stretching and breaking of the fabric from floating to other places, thereby ensuring the cleanliness of the testing environment.
