Vertical; the second telescopic rod 400 is a rod-shaped structure, which is vertically arranged on the top of the partition plate 300, and the second telescopic rod 400 can be telescoped along the length direction, and a synchronous belt mechanism is provided on the top; the ball screw 500 is a rod-shaped structure, which is arranged on the top of the base 100, and extends upward through the partition plate 300 and is connected to the synchronous belt mechanism, and the ball screw 500 can be telescoped along the length direction; the rotating mechanism is arranged on the partition plate 300, and the first telescopic rod 200 telescopes up and down along the length direction to drive the partition plate 300 to move up and down, thereby adjusting the height of the rotating mechanism.

[0024] Specifically, the base 100 is provided to fix the first telescopic rod 200 and the ball screw 500 on the top of the table. The lower ends of the first telescopic rod 200 and the ball screw 500 are connected to the top of the base 100.

In order to be able to set a partition plate 300 between the first telescopic rod 200 and the second telescopic rod 400, the partition plate 300 also plays a certain supporting role. The upper end of the first telescopic rod 200 is connected to the bottom of the partition plate 300, and the lower end of the second telescopic rod 400 is connected to the top of the partition plate. The ball screw 500 is mainly used to connect with the synchronous belt mechanism, which drives the ball screw 500 to extend and retract. The rotating mechanism is provided on the partition plate 300, and the extension and retraction of the ball screw 500 drives the partition plate 300 to move up and down, thereby adjusting the height of the rotating mechanism.

[0025] In one possible implementation, there are four first telescopic rods 200, the lower ends of the four first telescopic rods 200 are respectively arranged at the four corners of the top of the base 100, and the upper ends of the four first telescopic rods 200 are respectively arranged at the four corners of the bottom of the partition plate 300.

[0026] Specifically, such as Figure 1 As shown, since the stretching mechanism is relatively large, the first telescopic rod 300 plays the role of supporting the stretching mechanism. Therefore, multiple first telescopic rods 200 are provided. For the sake of aesthetics and symmetry, four first telescopic rods 200 are provided. The four first telescopic rods 200 are respectively provided at the four corners of the top of the base 100 to disperse the weight of the stretching mechanism.

[0028] Specifically, such as Figure 1 As shown, because the synchronous belt mechanism at the top has a certain weight, the second telescopic rods 400 are also provided in plurality. In order to match the first telescopic rod 200, the second telescopic rods 400 are also provided in four. The four second telescopic rods 400 are respectively provided at the four corners of the top of the partition plate 300, and the positions correspond to the telescopic rods 200.

[0030] Specifically, such as Figure 1 As shown, the ball screw 500 can not only control the movement of the synchronous belt, but also adjust the height. Therefore, the ball screw 500 is set at the center of the top surface of the base 100, and in the middle of the four first telescopic rods 200. The ball screw 500 passes through the center of the partition plate 300, and in the middle of the four second telescopic rods 400, and finally passes through the synchronous belt mechanism and is connected to the synchronous belt.

[0032] Specifically, such as Figure 1 As shown, it includes two telescopic groups. There is a certain distance between the two telescopic groups in order to set up a stretching mechanism, and the two ends of the synchronous belt mechanism are respectively connected to the top of the two telescopic groups.

[0033] In one possible implementation, a bearing 600 is provided between the first telescopic rod 200 and the base 100 . The bearing 600 is also provided between the first telescopic rod 200 and the partition plate 300 and between the second telescopic rod 400 and the partition plate 300 .

The electrical energy is transmitted to the first telescopic rod 200 through the bearing 600, so that the first telescopic rod 200 and the second telescopic rod 400 can receive the telescopic signal.

[0035] In a possible implementation, extension plates extend downward from the inner sides of the two partition plates 300 , and both ends of the rotating mechanism are connected to the two extension plates respectively.

[0036] Specifically, such as Figure 1 As shown, in order to facilitate the connection between the rotating mechanism and the partition plate 300, an extension plate is extended downward for a certain distance below the inner side of the partition plate 300 to form the extension plate, and the two ends of the rotating mechanism are connected to the extension plate so that the rotating mechanism is set between the two telescopic groups.

[0037] In one possible implementation, a rotating motor is provided on the partition plate 300, and the rotating motor is electrically connected to the rotating mechanism; the ball screw 500 is electrically connected to the telescopic motor on the synchronous belt mechanism; and a shell 600 is provided on the periphery of each telescopic group.

[0038] Specifically, such as Figure 1 As shown, a rotating motor is provided on the partition plate 300 on the right side. The rotating motor is provided to control the stretching mechanism to perform rotational stretching, and the telescopic motor is provided to control the first telescopic rod 200, the second telescopic rod 400 and the ball screw 500 to adjust the height by telescoping. For the overall aesthetics, a shell is provided on the periphery of each telescopic group.

[0039] When using the present invention: first install the parts on the table and connect the parts to the stretching mechanism. After the parts are connected to the stretching mechanism, power on the testing device. Then, according to the actual situation, control the telescopic height of the first telescopic rod 200, the second telescopic rod 400 and the ball screw 500, thereby adjusting the height of the stretching mechanism for repeated stretching, so that the parts receive tension at different heights.

[0040] The present application sets a base 100, a first telescopic rod 200, a partition plate 300, a second telescopic rod 400 and a ball screw 500, and a base 100, four first telescopic rods 200, a partition plate 300, four second telescopic rods 400 and a ball screw 500 form a telescopic group, and two telescopic groups are set. The first telescopic rod 200, the second telescopic rod 400 and the ball screw 500 of each group can move up and down with the stretching mechanism. Through the above setting, the present application can extend and retract the first telescopic rod 200, the second telescopic rod 400 and the ball screw 500, thereby driving the stretching mechanism to move up and down. While the stretching mechanism repeatedly stretches the parts, it can also move up and down, so that the parts are subjected to tension at different heights to test the toughness of the parts.

[0041] The above description is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field, within the scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and concept of the present invention, should be covered by the protection scope of the present invention.
