[0028] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Example 1

[0030] like Figure 1-6 As shown, a strength testing device for coated wool and cashmere fabrics comprises a No. 1 handle 1 and a No. 2 handle 2 whose ends are hinged to each other, and the No. 1 handle 1 and the No. 2 handle 2 are made of iron. A No. 1 shell 3 is fixedly mounted on the No. 1 handle 1, and a No. 1 circular groove 4 is provided on the No. 1 shell 3, and a No. 1 clamping member 5 is rotatably mounted in the No. 1 circular groove 4.

[0031] A second housing 6 is fixedly mounted on the second handle 2, and a second round groove 7 is provided on the second housing 6. A turntable 8 is rotatably mounted in the second round groove 7, and an electronic tensile scale 9 is fixedly mounted on the turntable 8. The range of the electronic tensile scale 9 is 50Kg, which can provide sufficient tension.

[0032] The electronic tensile scale 9 comprises a scale hook 10 , on which a second clamping member 11 is fixedly mounted.

[0033] It should be noted that before testing, the coated wool and cashmere fabric z is cut into strips of standard size, with a size of 10cm*1cm (adjustable appropriately). Use the No. 1 clamp 5 and the No. 2 clamp 11 to clamp the two ends of the strip of coated wool and cashmere fabric z in the length direction, and hold the No. 1 handle 1 and the No. 2 handle 2 with one hand so that the free ends of the No. 1 handle 1 and the No. 2 handle 2 are close to each other, thereby making the No. 1 clamp 5 and the No. 2 clamp 11 away from each other (the opposite of the principle of scissors). When the fabric z is tightened, continue to hold it tightly until the fabric z breaks, and judge the strength of the fabric z by the maximum reading of the electronic tensile scale 9 when the fabric z breaks. The larger the reading, the higher the strength of the fabric z.

[0034] If there is no time to observe the reading of the electronic tensile scale 9, the maximum value of the reading can be checked in the playback by recording a video.

[0035] Among them, the No. 1 clamping piece 5 and the electronic tensile scale 9 can both rotate. When the length of the fabric z is extended, the relative position and angle of the No. 1 handle 1 and the No. 2 handle 2 change, and the No. 1 clamping piece 5 and the electronic tensile scale 9 continue to maintain the vertical stretching of the fabric z.

[0036] In order to prevent the No. 1 handle 1 and the No. 2 handle 2 from violently colliding after the fabric z is broken, a spring or a buffer pad can be installed on the No. 1 handle 1 or the No. 2 handle 2 so that the No. 1 handle 1 and the No. 2 handle 2 will not produce a hard collision.

[0037] In the above embodiment, the No. 1 clamping member 5 and the No. 2 clamping member 11 have the same structure, both including a base plate 12, on which a pressing plate 13 is rotatably mounted. The size of the base plate 12 is larger than that of the pressing plate 13, and the base plate 12 of the No. 1 clamping member 5 is rotatably mounted in the No. 1 circular groove 4, which has a notch, and the notch faces the direction of the No. 2 handle 2, so that when the No. 1 clamping member 5 clamps the fabric z, the fabric z will not come into contact with the No. 1 shell 3.

[0038] Among them, a plurality of grooves 14 are provided on the plate surface of the substrate 12, and a plurality of bosses 15 corresponding to the grooves 14 are fixedly provided on the pressing plate 13. When the pressing plate 13 and the substrate 12 are pressed together, the bosses 15 enter the grooves 14, and the fabric z can be pressed into the grooves 14, so that the fabric z can be fully fixed. Because the force of the fabric z during stretching is not in the same direction as the direction of rotation of the pressing plate 13, the pressing plate 13 will not bounce off. In order to improve the clamping effect on the fabric z, a magnetic block can be fixedly installed on the pressing plate 13, and the magnetic attraction between the magnetic block and the iron substrate 12 is used to ensure that the pressing plate 13 will not loosen during the process of clamping the fabric z. A buckle can also be provided on the pressing plate 13, so that the pressing plate 13 is firmly connected to the substrate 12 when buckled on the substrate 12.

[0039] This fixing method can achieve quick fixation of fabric z. Compared with the tensile testing machine, there is no need to tie knots and tighten the two ends of fabric z, and it also reduces the problem of loosening caused by loose knots during the stretching process of fabric z.

[0040] Furthermore, the distance between the free ends of handle No. 1 and handle No. 2 and their rotation center is greater than the distance between clamp No. 1 5 and clamp No. 2 11 and the rotation center, so that handle No. 1 and handle No. 2 are force-saving levers that can produce a greater stretching effect on fabric z when using less force.

[0041] Furthermore, a bracket 16 is rotatably mounted on the No. 1 handle 1, a rotating shaft is rotatably mounted on the bracket 16, a rotating member 17 and a rotating handle 18 are fixedly mounted on both ends of the rotating shaft, the rotating member 17 is a gear, and a plurality of tooth grooves 19 are provided on the No. 2 handle 2.

[0042] It should be noted that when the fabric z is strong and the user has less strength, the bracket 16 is rotated and the gear is inserted into the tooth groove 19. The gear is rotated by rotating the handle 18, so that the gear is displaced relative to the second handle 2 along the length direction of the second handle 2. During the rotation of the gear, the pulling force of the bracket 16 on the gear is converted into a downward pressure on the second handle 2, which is a labor-saving lever, thereby reducing the angle between the second handle 2 and the first handle 1.

[0043] The pressing process can be performed simultaneously with manual tightening.

[0044] Furthermore, a ring-shaped cutting blade 20 for cutting fabric z is fixedly installed on handle No. 1, and a mold 21 is fixedly installed on handle No. 2. The fabric z to be cut is placed on the mold 21, and the cutting blade 20 is used to accurately cut the fabric z. The fabric z at the cutting point is just the right size, which not only improves the detection efficiency, but also improves the detection accuracy.

[0045] At the same time, the inner cavity of the mold 21 is improved so that after the cutting blade 20 enters the inner cavity of the mold 21, a closed space is formed between the inner cavities of the mold 21. When the cutting blade 20 continues to enter the mold 21, the gas in the closed space is compressed, thereby hindering the tendency of handle No. 1 and handle No. 2 to approach each other, further reducing the probability of a violent collision between handle No. 1 and handle No. 2, and the buffering effect is softer than that of a spring.

[0046] Furthermore, an air cylinder is fixedly installed on handle No. 1, and grooves are provided on the base plates of clamping piece No. 1 and clamping piece No. 2, in which a telescopic rod connected to the air cylinder is fixedly installed for extending when the air cylinder is shortened and for pushing open the pressure plate, and the telescopic rod is located on the base plate away from the side where it is hinged with the pressure plate.

[0047] The telescopic rod comprises a first section a and a second section b, and the second section b is provided with a plurality of air holes.

[0048] It should be noted that when the fabric z breaks, the distance between the No. 1 handle 1 and the No. 2 handle 2 is rapidly shortened, so that the No. 2 handle 2 contacts the gas cylinder 22 on the No. 1 handle 1, thereby shortening the length of the gas cylinder 22. The gas in the gas cylinder 22 enters the telescopic rod 23 through the air pipe, so that the first section a of the telescopic rod 23 is extended and extends out of the groove 14, and the first section a lifts the pressing plate 13.

[0049] When the first section a moves to the air hole 24 , the air cylinder 22 is exposed, and the gas in the second section b is ejected from the air hole 24 , so as to blow away the broken fabric z at the substrate 12 .

[0050] The air pump 22 is a common air pump 22, and its first function is to provide air to the telescopic rod 23, so that the telescopic rod 23 can push the pressure plate 13 open without the need for the user to manually pry it open. The second function is to provide air to the telescopic rod 23 to blow away the fabric z at the base plate 12, so that the user can directly carry out the next test, thereby improving the test efficiency. The third function is to provide reverse resistance to the movement of the second handle 2, so that the second handle 2 can slowly stop rotating.

[0051] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
