It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0032] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0033] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0034] Pull-out force testing is a test method used to measure the force a material can withstand during stretching or drawing. This test is designed to evaluate a variety of important material performance indicators, including strength, toughness, and deformation capacity. Pull-out force testing applies a tensile force, causing stress and deformation in the material. The tensile properties of the material are then calculated by measuring the deformation and applied force. These properties are key factors in evaluating material quality and selecting materials. The importance of pull-out force testing lies in its ability to provide information about the mechanical properties of a material under specific conditions, which is of great significance for product design, material selection, and engineering quality assurance. Therefore, the design of a pull-out force testing device is very necessary. However, most current pull-out force testing devices use two independent steel blocks to clamp the object being tested. This method can easily cause the object being tested to detach during clamping, making it inconvenient for the operator to operate during the clamping process.

[0035] Based on this, see Figure 1 The pull-out force detection device 1000 provided in the embodiment of the present invention can effectively improve the above-mentioned technical problems. The pull-out force detection device 1000 can make the clamping process more convenient and ensure that the object 2000 being tested is not likely to fall off during the clamping process.

[0036] Figure 1 This is a schematic diagram of a pull-out force detection device 1000 provided in an embodiment of the present invention, as shown in FIG. Figure 1 As shown, the pulling force detection device 1000 provided in this embodiment includes a first chuck 100 and a second chuck 200, the first chuck 100 includes a first chuck base 110, a first locking and fixing block 120, a second locking and fixing block 130 and a locking member 140, the first locking and fixing block 120 is connected to the first chuck base 110; the first locking and fixing block 120 and the second locking and fixing block 130 are movably connected, and a clamping opening is formed on the side away from the first chuck base 110. Opening 150; the first locking and fixing block 120 and the second locking and fixing block 130 form one side of the clamping opening 150 connected by a locking member 140; the locking member 140 is used to move the side of the clamping opening 150 formed by the first locking and fixing block 120 and the second locking and fixing block 130 closer to or farther away from each other, so as to enlarge or reduce the clamping opening 150, thereby being used to loosen or clamp one end of the object to be measured 2000; the second chuck 200 is used to clamp the other end of the object to be measured 2000.

[0037] Specifically, the locking member 140 in this embodiment is a quick-lock screw. A quick-lock screw is a self-tapping screw that does not require a nut to be used. It has self-tapping capabilities and can be directly screwed into the material to form threads, thereby fixing the connection. By making a threaded bottom hole on the connected part and then screwing the self-tapping screw in, quick fixation is achieved. The design of the quick-lock screw simplifies the installation process and improves work efficiency. In addition, some types of quick-lock screws also have strong locking and anti-loosening functions. Of course, the locking member 140 can also be replaced by a bolt and a self-locking nut, or other connectors with a locking function, which is not limited here.

[0038] By flexibly connecting the first locking block 120 and the second locking block 130, the positions of the first locking block 120 and the second locking block 130 are relatively fixed. During the clamping process of the object 2000, there is no need to worry about the first locking block 120 and the second locking block 130 becoming disconnected, causing the object 2000 to fall off. Furthermore, a clamping opening 150 is formed between the first locking block 120 and the second locking block 130, allowing the object 2000 to be placed into the clamping opening 150. The provision of a locking member 140 allows the size of the clamping opening 150 to be adjusted to clamp objects 2000 of varying sizes for pull-out force testing. During the clamping process of the object 2000, only the locking member 140 needs to be adjusted to release or clamp the object 2000, eliminating the need to fix the relative positions of the two locking blocks. This simplifies the clamping process and ensures that the object 2000 is unlikely to fall off during the clamping process.

[0039] Because the first and second locking blocks 120, 130 are connected by a locking member 140 to adjust the size of the clamping opening 150, they also have other connections. They are interconnected and not separate blocks. Therefore, when clamping the object 2000, there is no need to first position the first and second locking blocks 120, 130 relative to each other to ensure alignment for clamping the object 2000. Clamping or releasing the object 2000 is achieved by simply adjusting the position of the locking member 140 relative to the first and second locking blocks 120, 130. Furthermore, because the first locking block 120 and the second locking block 130 are movably connected at the end away from the clamping opening 150, the first locking block 120 and the second locking block 130 will not slip relative to each other during the operator's adjustment of the locking member 140, thereby preventing the object 2000 from falling off. Furthermore, the first locking block 120 and the second locking block 130 will not become disconnected due to excessive adjustment of the locking member 140 by the operator.

[0040] Please continue reading Figure 1 In this embodiment, the second chuck 200 includes a second chuck base 210 and a clamping member 220. The clamping member 220 is connected to the second chuck base 210, and the clamping member 220 is used to clamp one end of the object to be measured 2000. Specifically, the clamping member 220 in this embodiment includes a third clamping block 221 and a fourth clamping block 222. The third clamping block 221 and the fourth clamping block 222 are arranged at intervals, and the third clamping block 221 and the fourth clamping block 222 are used together to clamp one end of the object to be measured 2000. Of course, the number of clamping blocks 160 can also be three, four, or multiple, and is not limited here. Multiple clamping blocks 160 together enclose a clamping space for clamping one end of the object to be measured 2000. In order to clamp the object 2000 to be measured, which has a flat surface at one end and a stepped surface at the other, the first chuck 100 and the second chuck 200 in this embodiment have different clamping structures. Of course, the clamping structures of the first chuck 100 and the second chuck 200 can be changed according to the structure of the object 2000 to be measured. The structure of the first chuck 100 and the structure of the second chuck 200 can be the same, such as both being designed as the structure of the first chuck 100 or both being designed as the structure of the second chuck 200, depending on the actual situation and is not limited here.

[0041] Figure 2 This is a schematic diagram of the first chuck 100 provided in an embodiment of the present invention without the first chuck base 110, see Figure 2In this embodiment, the first locking block 120 includes a connecting block 121 and a clamping block 122. The connecting block 121 is connected to the first chuck base 110, which is then connected to the clamping block 122. The connecting block 121 is movably connected to the second locking block 130 via a rotating shaft. The second locking block 130 and the clamping block 122 are positioned opposite each other to form a clamping opening 150. The clamping block 122 defines a first mounting hole 1221, and the second locking block 130 defines a second mounting hole 131. The first mounting hole 1221 and the second mounting hole 131 are positioned correspondingly. The locking member 140 is positioned within the first mounting hole 1221 and the second mounting hole 131. By adjusting the position of the locking member 140 within the first mounting hole 1221 and the second mounting hole 131, the clamping opening 150 is adjusted to be larger or smaller, thereby allowing the first locking block 120 and the second locking block 130 to be used together to release or clamp the object 2000 being measured. In detail, the connecting block 121 is provided with a groove, and through holes are provided on both sides of the groove. The rotating shaft passes through the through holes, and the rotating shaft is located in the groove of the connecting block 121. A second locking and fixing block 130 is provided in the middle of the rotating shaft, and the second locking and fixing block 130 is also located in the groove. With this design, the connection stability between the second locking and fixing block 130 and the connecting block 121 can be guaranteed. Of course, the first locking and fixing block 120 can also be movably connected to the structures on both sides of the groove of the connecting block 121 through two rotating shafts, each rotating shaft is only partially located in the first locking and fixing block 120, and penetrates the first locking and fixing block 120 along the axis of the through hole. Alternatively, the first locking and fixing block 120 and the connecting block 121 adopt other movably connected methods, which are not limited here.

[0042] In order to facilitate the replacement of the first locking and fixing block 120, the second locking and fixing block 130 and the locking member 140, please refer to Figure 2 , and combined with Figure 1 In this embodiment, the first chuck 100 further includes a clamping block 160, which is connected to the first chuck base 110 and clamped to the first locking and fixing block 120. Of course, the clamping block 160 can also be snap-fitted to the first locking and fixing block 120 or connected with threaded fasteners such as bolts. As long as the clamping block 160 and the first locking and fixing block 120 are detachably connected, the specific connection method is not limited herein.

[0043] For details, please refer to Figure 2 , and combined with Figure 1, in the embodiment, the clamping block 160 includes a first clamping block 161 and a second clamping block 162. The first clamping block 161 and the second clamping block 162 are arranged at intervals, and the first clamping block 161 and the second clamping block 162 are jointly used to clamp the first locking and fixing block 120. Of course, the number of the clamping blocks 160 can also be three, four or more, which is not limited herein. The plurality of clamping blocks 160 jointly enclose a clamping space for clamping the first locking and fixing block 120.

[0044] To make the connecting block 121 easier to connect with the first chuck base 110, please refer to Figure 2 and combine with Figure 3 , Figure 3 is a schematic diagram of the first locking and fixing block 120 provided in the embodiment of the present invention. In this embodiment, the cross-sectional shape of the connecting block 121 is "7" shaped. Specifically, the connecting block 121 in this embodiment includes a first connecting block 1211 and a second connecting block 1212. The first connecting block 1211 and the second connecting block 1212 are perpendicularly connected. The clamping block 122 is connected to the first connecting block 1211, and the second locking and fixing block 130 is connected to the first connecting block 1211 through a rotating shaft; the second connecting block 1212 is connected to the first chuck base 110. The first connecting block 1211 and the second connecting block 1212 are perpendicularly connected, which can increase the distance between the second locking and fixing block 130 and the second connecting block 1212, so that there is enough space for the second connecting block 1212 to connect with the first chuck base 110, ensuring the stability of the connection between the second connecting block 1212 and the first chuck base 110, improving the stability of the toilet, and further improving the detection efficiency. Of course, the first connecting block 1211 and the second connecting block 1212 can also be connected at other angles, such as acute angle, obtuse angle connection, etc., which is not limited herein.

[0045] In addition, the cross-sectional shape of the connecting block 121 can also be other shapes such as "匚" shaped, "T" shaped, etc., as long as it is convenient for the first locking and fixing block 120 to connect with the first chuck base 110. The specific design of the shape is not limited herein.

[0046] Figure 4 is a schematic diagram of the second locking and fixing block 130 provided in the embodiment of the present invention. Please refer to Figure 4 and combine with Figure 1, a protrusion 132 is provided on the side of the second locking and fixing block 130 away from the first chuck base 110 and facing the first locking and fixing block 120. By providing the protrusion 132 facing the first locking and fixing block 120, it is convenient to clamp the object 2000 to be measured having a protruding structure at one end. Of course, a corresponding protrusion 132 structure can also be provided on the side of the first locking and fixing block 120 away from the first chuck base 110 and facing the second locking and fixing block 130 to clamp the object 2000 to be measured, improve the clamping strength, and ensure the stability of the clamping. In addition, the structure of the side of the first locking and fixing block 120 and / or the second locking and fixing block 130 away from the first chuck base 110 can be designed accordingly according to the structural shape of the end of the object 2000 to be measured, and is not limited here.

[0047] According to a pull-out force detection device 1000 provided in this embodiment, its working principle is as follows:

[0048] To perform a pull-out force test on an object 2000, first loosen the first and second locking blocks 120, 130 using the locking member 140 to enlarge the clamping opening 150. The object 2000 is then placed into the clamping opening 150. The locking member 140 is then adjusted to bring the sides of the clamping opening 150, formed by the first and second locking blocks 120, 130, closer together, thereby narrowing the clamping opening 150 and clamping one end of the object 2000. The other end of the object 2000 is then clamped by the second chuck 200. Finally, a pull-out force test is performed on the object 2000.

[0049] In summary, the pulling force detection device 1000 includes a first chuck 100 and a second chuck 200. The first chuck 100 includes a first chuck base 110, a first locking and fixing block 120, a second locking and fixing block 130, and a locking member 140. The first locking and fixing block 120 is connected to the first chuck base 110; the first locking and fixing block 120 and the second locking and fixing block 130 are movably connected, and a clamping opening 1 is formed on a side away from the first chuck base 110. 50; the first locking block 120 and the second locking block 130 are connected on one side of the clamping opening 150 by a locking member 140; the locking member 140 is used to move the side of the clamping opening 150 formed by the first locking block 120 and the second locking block 130 closer to or farther away from each other, so as to enlarge or reduce the clamping opening 150, thereby loosening or clamping one end of the object to be measured 2000; the second clamp 200 is used to clamp the other end of the object to be measured 2000. By movably connecting the first locking block 120 and the second locking block 130, the positions of the first locking block 120 and the second locking block 130 are relatively fixed. During the process of clamping the object to be measured 2000, there is no need to worry about the first locking block 120 and the second locking block 130 being disconnected, causing the object to be measured 2000 to fall off. A clamping opening 150 is formed between the first locking block 120 and the second locking block 130, allowing the object 2000 to be placed into the clamping opening 150. The clamping member 140 allows the size of the clamping opening 150 to be adjusted to accommodate objects 2000 of varying sizes for pull-out force testing. During the clamping process, the object 2000 can be loosened or clamped by simply adjusting the locking member 140, eliminating the need to fix the relative positions of the two locking blocks. This simplifies the clamping process and ensures that the object 2000 does not easily fall out during the clamping process.
