[0032] The inside of the control block 402 is provided with a moving control groove, and the outside of the operating rod 401 is provided with a switching rod 4011 which is inserted into the inside of the moving control groove, the moving control groove is composed of a lifting groove 4021 and a locking groove 4022, the lifting groove 4021 is arranged obliquely, and the locking groove 4022 is arranged along the axial direction of the driving rod 103, the top end of the lifting groove 4021 is connected with one end of the locking groove 4022, the bottom of the control block 402 is provided with a moving thread groove 4023, and the rod body of the driving rod 103 is provided with a thread outside, the rod body of the driving rod 103 passes through the inside of the moving seat 301, and the driving rod 103 is threadedly connected with the moving thread groove 4023, in use, when the test assembly is in the reset state (the operating rod 401 is not pressed by external force), the tension mechanism 3 is in the test mode, at this time, the test assembly can test the tension performance of the clothing fabric, and the test is convenient and flexible, after the two ends of the fabric are fixed in the inside of the fixed clamp 201 and the follow-up clamp 202, the power supply of the driving motor 104 is turned on to start the test, when the test assembly is in the reset state, under the action of the locking top spring 4012, the switching rod 4011 is inserted into the inside of the locking groove 4022, so that the control block 402 cannot change the radial position, therefore, the moving thread groove 4023 and the driving rod 103 can be stably threadedly connected, when the driving motor 104 is powered, the driving rod 103 can be driven to rotate, when the rod body thread of the driving rod 103 rotates, the moving seat 301 can be driven to move by the control block 402 for testing, by changing the rotating direction of the driving rod 103, the moving direction of the moving seat 301 can be changed, so that when the moving seat 301 moves towards the direction away from the fixed clamp 201, the function of supporting the clothing fabric and testing the tension can be realized, after the test is completed, the moving seat 301 can be moved towards the direction close to the fixed clamp 201 to reset, so as to be ready for the test of subsequent fabric, and the test is convenient and flexible.

[0033] The side of the moving seat 301 is provided with a positioning rod, and the outer end of the positioning rod is provided with a thread, the pressure disc 303 is screwed on the outside of the positioning rod through the thread, and the positioning rod is inserted into the inside of the test seat 302. In use, when the test assembly is used to test the tensile strength of the clothing fabric, the moving seat 301 and the test seat 302 are at the minimum distance under the action of the pressure spring 3031 at the initial stage of the test, and the test seat 302 moves with the moving seat 301. With the movement of the moving seat 301, the clothing fabric is stretched, so that the test seat 302 cannot move with the moving seat 301 under the limiting action of the fabric. The side of the pressure disc 303 is provided with a pressure spring 3031, and the two ends of the pressure spring 3031 abut against the side of the pressure disc 303 and the side of the test seat 302 respectively. Thereafter, the moving seat 301 moves alone, and the pressure spring 3031 can be compressed by the pressure disc 303 when the moving seat 301 moves alone. The compressed pressure spring 3031 can transmit force to the test seat 302, so that the test seat 302 applies tension to the fabric to realize the tensile test of the fabric. The more intense the compression of the pressure spring 3031, the greater the tension applied to the fabric by the test seat 302, and the greater the distance between the test seat 302 and the moving seat 301. The distance sensor 304 can monitor the distance between the moving seat 301 and the test seat 302, so that the change in distance between the test seat 302 and the moving seat 301 can be obtained by monitoring the change in distance between the test seat 302 and the moving seat 301 by the distance sensor 304, and the change in tensile force and the tensile force value can be obtained. The test is convenient and flexible.

[0034] The tensile mechanism 3 further comprises a one-way damping rod 305, and the two ends of the one-way damping rod 305 are fixedly connected to the sides of the moving seat 301 and the test seat 302. The one-way damping rod 305 has damping when it is contracted. In use, the test assembly has a fracture buffering function, which avoids the phenomenon that the pressure spring 3031 is instantaneously released due to the rupture of the fabric during the test, causing damage to the device. The use is stable. When the distance between the moving seat 301 and the test seat 302 increases, the one-way damping rod 305 is elongated at this time. The damping force of the one-way damping rod 305 when it is elongated can be ignored and will not affect normal test use. When the fabric is ruptured, the test seat 302 will move towards the moving seat 301 under the action of the pressure spring 3031. When the distance between the test seat 302 and the moving seat 301 decreases, the one-way damping rod 305 will contract, so that the one-way damping rod 305 will buffer the elasticity of the pressure spring 3031 when it is contracted, so as to ensure that the test seat 302 is stably and slowly attached to the side of the moving seat 301, without impact phenomenon. At the same time, the fracture buffering function also facilitates the process of unloading (the moving seat 301 moves towards the fixed clamp 201 to reset) after the test is completed. The test seat 302 can also be stably and slowly attached to the side of the moving seat 301, and the use is stable.

[0035] The outer part of the adjusting rod 102 is provided with an adjusting gear 1021, and the outer part of the pressure disc 303 is provided with a positioning gear 3032, the teeth of the adjusting gear 1021 and the positioning gear 3032 are in meshing transmission, and the axial setting length of the adjusting gear 1021 covers the movement range of the pressure disc 303 following the movement of the moving base 301, in use, the initial force of the test assembly can be freely adjusted and controlled during testing, and it can be adapted to the tension test of different specifications of clothing fabrics, when the adjusting rod 102 is rotated, the adjusting gear 1021 of the adjusting rod 102 can drive the pressure disc 303 to rotate through the positioning gear 3032, the pressure disc 303 can change the use position by moving outside the positioning rod through the thread outside the positioning rod when rotating, the change of the use position of the pressure disc 303 changes the initial extension length of the pressure top spring 3031 when the test assembly is reset, that is, the initial pressure value applied to the clothing fabric at the beginning of the test, the adjustment is convenient, flexible and highly adaptable.

[0036] The side surface of the operating rod 401 is provided with a locking top spring 4012, and the two ends of the locking top spring 4012 are respectively abutted against the side surface of the operating rod 401 and the side surface of the moving base 301, in use, the use mode of the tension mechanism 3 can be adjusted through the linkage mechanism 4, when the operating rod 401 is not pressed by external force, the tension mechanism 3 is in test mode, when the operating rod 401 is pressed, the locking top spring 4012 is compressed, and the tension mechanism 3 is in adjustment mode, the switching rod 4011 can enter the inside of the lifting groove 4021 from the locking groove 4022 after the operating rod 401 is pressed, so that the control block 402 can move upwards under the guidance of the switching rod 4011 to the locking groove 4022, so that the threaded cooperation between the moving threaded groove 4023 and the driving rod 103 is released, thereafter, the tension mechanism 3 can be directly driven to move in the inside of the mounting base 101 to change the use position by pulling the moving base 301, so as to quickly position the use position of the follow-up clamp 202, quickly adapt the tension test of different length fabrics, further improve the adaptability of the device, after the follow-up clamp 202 is positioned to the required position, the operating rod 401 can be automatically reset under the action of the locking top spring 4012 after the operating rod 401 is opened, so that the tension mechanism 3 re recovers to the test mode for use.

[0037] The driving motor 104 and the distance sensor 304 are electrically connected with the external power supply and the control device, and the specific structure and working principle are both existing mature technologies, which will not be repeated here.

[0038] The specific use mode and role of the embodiment are as follows: in the application, the use mode of the tension mechanism 3 can be adjusted through the linkage mechanism 4, when the operating rod 401 is not pressed by external force, the tension mechanism 3 is in the test mode, when the operating rod 401 is pressed, the locking top spring 4012 is compressed, and the tension mechanism 3 is in the adjustment mode, the switching rod 4011 can enter the inside of the lifting groove 4021 from the locking groove 4022 after being pressed, so that the control block 402 can move upwards under the guidance of the switching rod 4011 to the locking groove 4022, thereby releasing the threaded cooperation between the moving threaded groove 4023 and the driving rod 103, and then the tension mechanism 3 can be directly driven to move in the inside of the mounting seat 101 to change the use position, so that the use position of the follow-up clamp 202 can be quickly positioned, and the tension test of the cloth with different lengths can be quickly adapted, after the follow-up clamp 202 is positioned at the required position, the operating rod 401 can be automatically reset under the action of the locking top spring 4012 after being opened, so that the tension mechanism 3 returns to the test mode for use, when the test assembly is in the reset state (the operating rod 401 is not pressed by external force), the tension mechanism 3 is in the test mode, at this time, the test assembly can test the tension performance of the clothing cloth, after the two ends of the cloth are fixed in the inside of the fixed clamp 201 and the follow-up clamp 202, the power supply of the driving motor 104 can be turned on to start the test, when the test assembly is in the reset state, the switching rod 4011 is inserted in the inside of the locking groove 4022 under the action of the locking top spring 4012, so that the control block 402 cannot change the radial position, so the threaded cooperation between the moving threaded groove 4023 and the driving rod 103 can be stable, when the driving motor 104 is powered, the driving rod 103 can be driven to rotate, when the driving rod 103 rotates, the rod body thread can drive the moving seat 301 to move through the control block 402 for testing, the moving direction of the moving seat 301 can be changed by changing the rotating direction of the driving rod 103, so that when the moving seat 301 moves away from the fixed clamp 201, the function of supporting the clothing cloth and testing the tension can be realized, after the test is completed, the moving seat 301 can be reset by moving towards the fixed clamp 201, so as to be ready for the test of subsequent cloth, when the test assembly tests the tension of the clothing cloth, the moving seat 301 and the test seat 302 are at the minimum distance under the action of the pressure top spring 3031 in the initial test period, and the test seat 302 moves with the moving seat 301, with the movement of the moving seat 301, the clothing cloth is supported, so that the test seat 302 cannot move with the moving seat 301 under the limiting action of the cloth, after that, the moving seat 301 moves alone, when the moving seat 301 moves alone, the pressure disc 303 can compress the pressure top spring 3031, after the pressure top spring 3031 is compressed, the force can be transmitted to the test seat 302,Therefore, the test seat 302 is used for applying tension to the fabric to realize tension test of the fabric. The more intense the compression of the compression top spring 3031 is, the greater the tension applied to the fabric by the test seat 302 is, and the greater the distance between the test seat 302 and the moving seat 301 is. Therefore, the change degree of the tension and the tension value can be obtained by monitoring the distance change between the test seat 302 and the moving seat 301 through the distance sensor 304. The test assembly has a fracture buffering function, which avoids the phenomenon that the device is damaged due to the instantaneous release of the compression top spring 3031 caused by the fabric fracture during the test process. The use is stable. When the distance between the moving seat 301 and the test seat 302 is large, the one-way damping rod 305 is elongated at this time. The damping force of the one-way damping rod 305 when it is elongated can be ignored and will not affect the normal test use. When the fabric fracture phenomenon occurs, the test seat 302 will move to the direction of the moving seat 301 under the action of the compression top spring 3031. When the distance between the test seat 302 and the moving seat 301 is reduced, the one-way damping rod 305 will contract. Therefore, the one-way damping rod 305 will buffer the elastic force of the compression top spring 3031 when it is contracted, so as to ensure that the test seat 302 is stably and slowly attached to the side surface of the moving seat 301, and the impact phenomenon will not occur. At the same time, the fracture buffering function also facilitates the unloading process (the moving seat 301 moves to the direction of the fixed clamp 201 to reset) after the test is completed. The test seat 302 can also be stably and slowly attached to the side surface of the moving seat 301. The initial force of the test assembly during the test can be freely adjusted and used, which can adapt to the tension test of different specifications of garment fabric. When the adjusting rod 102 is rotated, the adjusting gear 1021 of the adjusting rod 102 can drive the pressure disc 303 to rotate through the positioning gear 3032. The pressure disc 303 can move outside the positioning rod through the threads outside the positioning rod to change the use position when rotating. The change of the use position of the pressure disc 303 changes the initial extension length of the compression top spring 3031 when the test assembly resets, that is, the initial pressure value applied to the garment fabric when the test starts.
