[0046] Referring to Figure 1 and Figure 2 , two first power sources 102 are respectively installed on the two sides of the testing table 1, the power shafts of the first power sources 102 are connected with the first testing parts 2, for controlling the movement of the first testing parts 2; two second power sources 201 are respectively installed on one side of the first testing parts 2, the power shafts of the second power sources 201 are connected with the second testing parts 3, for controlling the movement of the second testing parts 3.

[0047] The first power sources 102 and the second power sources 201 all adopt air cylinders, and can also adopt linear motors, and the first power sources 102 and the second power sources 201 can drive the first testing parts 2 and the second testing parts 3 to stably and reliably operate during the testing process.

[0048] Referring to Figure 1 and Figure 3 , the testing table 1 comprises: two first moving holes 101, which are throughly arranged on the top of the testing table 1, the first testing parts 2 are installed in the first moving holes 101, the two first moving holes 101 not only provide space for the installation of the first testing parts 2, but also ensure that the first testing parts 2 can smoothly move left and right under the drive of the power sources, so that the testing table 1 can adapt to U-shaped hoops of different sizes and simulate pulling forces in different directions through the movement of the first testing parts 2.

[0049] Referring to Figure 1 and Figure 3 , the first testing part 2 comprises: a second moving hole 202, which is throughly arranged on the top of the first testing part 2, the second testing part 3 is installed in the second moving hole 202, the design of the second moving hole 202 provides convenience for the installation and movement of the second testing part 3, and the second testing part 3 moves on the first testing part 2 to simulate the front and back direction pulling force changes.

[0050] Referring to Figure 5The second testing part 3 comprises: an adjusting groove 301, which is arranged in the inner ring of the second testing part 3, and the clamping piece 4 is installed in the adjusting groove 301; a screw rod 302, which is installed in the adjusting groove 301 and connected with the clamping piece 4 at one end; a groove, which is arranged in the outer ring of the second testing part 3, and the other end of the screw rod 302 penetrates through the adjusting groove 301 and extends into the groove; a driving wheel 305, which is installed in the groove; a first bevel gear 306, which is installed on the top of the driving wheel 305; a second bevel gear 307, which is installed at one end of the screw rod 302 and connected with the first bevel gear 306; an outer ring plate 303, which is installed on the outer side of the second testing part 3; and a rack 304, which is installed in the inner ring of the outer ring plate 303 and connected with the driving wheel 305.

[0051] The clamping piece 4 can stably clamp and fix the U-shaped hoop. The clamping piece 4 is connected with the driving wheel 305 through the screw rod 302. When the outer ring plate 303 rotates, the rack 304 can be driven to move. The rack 304 can control the rotation of the driving wheel 305. When the driving wheel 305 rotates, the screw rod 302 can drive the clamping piece 4 to move towards or away from the center of the second testing part 3 through the transmission of the first bevel gear 306 and the second bevel gear 307, so as to adapt to U-shaped hoops of different sizes.

When the outer ring plate 303 rotates, the rack 304 can be driven to move. The rack 304 can control the rotation of the driving wheel 305. The rotation of the driving wheel 305 drives the screw rod 302 to rotate through the transmission of the first bevel gear 306 and the second bevel gear 307, and then drives the clamping piece 4 to move towards the center of the second testing part 3, so as to stably clamp the U-shaped hoop. When the U-shaped hoop is fixed, the operator can control the first power source 102 and the second power source 201 to simulate the tension test in different directions. The rotation of the first power source 102 drives the first testing part 2 to move in the first moving hole 101 on the test table 1, realizing the tension test in the left and right directions. At the same time, the second power source 201 controls the second testing part 3 to move in the second moving hole 202, and the two second testing parts 3 move in opposite directions, realizing the tension test in the front and back directions. The test device can more realistically simulate the complex stress conditions encountered by the U-shaped hoop in actual use.

[0054] Compared with the prior art, the test device has the following beneficial effects:

[0055] By simulating multi-direction and multi-angle stress conditions, the device can comprehensively evaluate the performance of the U-shaped hoop in the actual working environment, overcoming the limitation of the existing test device which can only perform single direction tension test.
