When the roller 707 is in the clamping block 10 position, the second spring 702 is in a compressed state, and multiple fixed frame ends 801 A first horizontal plate 802 is fixedly connected between the surfaces, a first inclined plate 803 is fixedly connected to the outer surface of the first horizontal plate 802, a plurality of support rods 804 are divided into two groups, the two groups of support rods 804 are symmetrically fixedly connected to the inner surface of the frame 1, a second horizontal plate 805 is fixedly connected between the end surfaces of the two groups of support rods 804, a second inclined plate 806 is fixedly connected to the outer surface of the second horizontal plate 805, the first horizontal plate 802 is located on the upper side of the second horizontal plate 805, the first inclined plate 803 and the second inclined plate 806 have the same inclination angle, and the pull rod 711 is located between the first horizontal plate 802 and the second horizontal plate 805.

[0033] In this embodiment, when testing the connection strength of the plug, the plug body 605 is inserted into the socket 604 from the upper position, so that the plug body 605 is connected to the connecting seat 603. After the motor 2 is running, it can drive the conveyor belt 5 to operate. The operation of the conveyor belt 5 can drive the connecting assembly 6 to move from the guide block 9 to the clamping block 10 at the center position. The pull rod 711 will move to the position between the first horizontal plate 802 and the second horizontal plate 805 as the conveyor belt 5 operates. As the connecting seat 603 continues to move, the pull rod 711 will follow the movement. The pull rod 711 will follow the movement between the first horizontal plate 802 and the second horizontal plate 805. After the pull rod 711 continues to move, it will move to the position between the first inclined plate 803 and the second inclined plate 806. At this time, the first The inclined plate 803 and the second inclined plate 806 can guide the movement trajectory of the pull rod 711. Since the first inclined plate 803 and the second inclined plate 806 are in an upwardly inclined state, the pull rod 711 will be guided to move upward while moving horizontally, so that the displacement trajectory of the pull rod 711 is consistent with the inclined state of the first inclined plate 803 and the second inclined plate 806. When the pull rod 711 moves upward, the pull rod 711 can drive the supporting plate 709 to move upward through the connection with the frame rod 710. After moving upward, the supporting plate 709 drives the first magnetic plate 712 to move upward. After moving upward, the first magnetic plate 712 is separated from the second magnetic plate 714. At the same time, the supporting plate 709 drives the third spring 708 to move upward. When the third spring 708 is subjected to an upward pulling force, the third magnetic plate 714 is disengaged from the second magnetic plate 714. The third spring 708 will be stretched and deformed, and at the same time, the third spring 708 will apply an upward pulling force to the side frame 703. Since the side frames 703 on both sides are in a clamping state with the plug body 605, the side frames 703 will also synchronously apply an upward pulling force to the plug body 605 when the force is applied. At this time, the plug body 605 is pulled up for connection strength detection through the pulling force of the side frames 703. As the pull rod 711 continues to move, the height of the pull rod 711 gradually increases as it moves along the path of the first inclined plate 803 and the second inclined plate 806. Therefore, the pull rod 711 will gradually apply a greater pulling force to the plug body 605, that is, the side frame 703 will apply a linearly increasing pulling force to the plug body 605 to realize connection strength detection. While applying the upward pulling force, the side frame 703 applies the pulling force upward to the first spring 607 through the connection between the second spring 702 and the partition frame 701, and then the pull rod 711 continues to move away from the first inclined plate 803 and the second inclined plate 806. After the bottom of the pull rod 711 loses the support of the second inclined plate 806, the rebound force of the third spring 708 can drive the supporting plate 709, the frame rod 710 and the pull rod 711 to move down and reset. At this time, the supporting plate 709 drives the first magnetic plate 712 to move downward. After the first magnetic plate 712 moves downward, it fits and adsorbs with the second magnetic plate 714 to limit and fix the position of the supporting plate 709. At the same time, the side frame 703 moves to the position of the guide block 9 on the other side, and the roller 707 contacts the inclined surface of the guide block 9 and moves outward.At this time, the side frame 703 is driven to move outward and reset by the rebound force of the second spring 702. After the side frame 703 moves, it is freed from the clamping of the plug body 605. The staff can directly take out the plug body 605 to complete the connection strength test.

[0034] Embodiment 2

[0035] Figure 4 and Figure 7 As shown, the inner surfaces of both sides of the frame 1 are fixedly connected with clamping blocks 10, and the inner surfaces of both sides of the frame 1 are symmetrically fixedly connected with guide blocks 9, the clamping block 10 is located between the two guide blocks 9, the clamping block 10 and the guide block 9 have equal thickness, the cross-section of the guide block 9 is inclined, the roller 707 matches the position of the guide block 9 and the clamping block 10, the plug body 605 is located between the two side frames 703, and the outer surface of the side frame 703 close to the plug body 605 is adhered with a rubber pad 704 for increasing friction, and the outer surface of the rubber pad 704 is in contact with the outer surface of the plug body 605, and when the roller 707 is at the clamping block 10 position, the second spring 702 is in a compressed state.

[0036] In this embodiment, the movement of the support 706 drives the roller 707 to follow the movement. As the roller 707 moves, the roller 707 will move to the position of the guide block 9. After the roller 707 contacts the inclined surface of the guide block 9, the roller 707 will be squeezed, thereby driving the support 706 to move. After the roller 707 moves to the position of the clamping block 10, the support 706 drives the side frame 703 to move toward the plug body 605 through the connection of the extension rod 705. At this time, the side frames 703 on both sides are in a fit state with the two side surfaces of the plug body 605, and the second spring 702 is compressed. Through the arrangement of the rubber pad 704 on the outer surface of the side frame 703, after the side frame 703 fits the surface of the plug body 605 and applies pressure, the rubber pad 704 is used to fill the surface. The rubber pad 704 can increase the friction force, so that the side frames 703 on both sides firmly clamp the plug body 605, thereby achieving the purpose of automatically clamping the plug body 605, and further improving the automation of the device.

[0037] Embodiment 3

[0038] Figure 7 As shown, the outer surface of the side frame 703 is symmetrically fixedly connected with an extension rod 705, the end surfaces of the two extension rods 705 are fixedly connected with a support 706, and the inner surface of the support 706 is rotatably connected with a roller 707.

[0039] In this embodiment, when the guide block 9 and the clamping block 10 cooperate to drive the side frame 703 to move and clamp the plug body 605, the support 706 and the roller 707 are arranged in coordination, and the roller 707 rolls on the surface of the guide block 9 and the clamping block 10, thereby reducing the friction and thus reducing the wear of the device during operation.

[0040] The use method and working principle of the device: when testing the connection strength of the plug, by setting a plurality of connection components 6 on the surface of the conveyor belt 5, the positions of the plurality of connection components 6 can respectively connect a plurality of plug bodies 605. When connecting the plug body 605, the plug body 605 is inserted into the jack 604 from the upper position, so that the plug body 605 is connected to the connection seat 603. At this time, the plug body 605 can be clamped and a pulling force can be applied upwards by using the detection component 7 and the guide component 8. The connection strength of the plug body 605 is tested by pulling the plug body 605 upwards. When the plug body 605 is inserted into the connection seat 603, the connection seat 603 is at the outer position of the guide block 9. At this time, the partition frame 70 The second springs 702 on both sides of 1 provide support for the two side frames 703 respectively. At this time, the plug body 605 is inserted into the socket 604 to complete the connection, and then the motor 2 is started to run. After the motor 2 runs, it can drive the driving roller 3 to follow the rotation. When the driving roller 3 rotates, the driving roller 3 and the supporting roller 4 can synchronously drive the conveyor belt 5 to operate. At this time, the operation of the conveyor belt 5 can drive the connecting component 6 to move from the guide block 9 to the clamping block 10 at the center position. As the connecting seat 603 continues to move, the side frame 703 can drive the support 706 to follow the movement through the connection of the extension rod 705, and the movement of the support 706 drives the roller 707 to follow the movement. As the roller 707 moves, the roller 707 will move to the guide block 9. At the guide block 9 position, after the roller 707 contacts the inclined surface of the guide block 9, the roller 707 will be squeezed to drive the support 706 to move. After the roller 707 moves to the clamping block 10 position, the support 706 drives the side frame 703 to move toward the plug body 605 through the connection of the extension rod 705. At this time, the side frames 703 on both sides are in a fit state with the two side surfaces of the plug body 605. At the same time, the second spring 702 is compressed. Through the setting of the rubber pad 704 on the outer surface of the side frame 703, after the side frame 703 fits the surface of the plug body 605 and applies pressure, the rubber pad 704 is used to fill the surface. The rubber pad 704 can increase the friction force, so that the side frames 703 on both sides firmly clamp the plug body 605 At this time, after the plug body 605 is clamped and fixed, as the connecting seat 603 continues to move, the supporting plate 709 on the top of the side frame 703 is at a fixed height position during displacement, and the first magnetic plate 712 and the second magnetic plate 714 are used together to fix the supporting plate 709 position, so at this time, the connection of the frame rod 710 makes the pull rod 711 at a fixed height, and the pull rod 711 will move to the position between the first horizontal plate 802 and the second horizontal plate 805 as the conveyor belt 5 runs. As the connecting seat 603 continues to move, the pull rod 711 is driven to follow the movement, and the pull rod 711 will follow the movement between the first horizontal plate 802 and the second horizontal plate 805. After the pull rod 711 continues to move, it will move to the position between the first inclined plate 803 and the second inclined plate 806.At this time, the first inclined plate 803 and the second inclined plate 806 can guide the movement trajectory of the pull rod 711. Since the first inclined plate 803 and the second inclined plate 806 are in an upwardly inclined state, the pull rod 711 will be guided to move upward while moving horizontally, so that the displacement trajectory of the pull rod 711 is consistent with the inclined state of the first inclined plate 803 and the second inclined plate 806. When the pull rod 711 moves upward, the pull rod 711 can drive the supporting plate 709 to move upward through the connection with the frame rod 710. After moving upward, the supporting plate 709 drives the first magnetic plate 712 to move upward. After moving upward, the first magnetic plate 712 is separated from the second magnetic plate 714. At the same time, the supporting plate 709 drives the third spring 708 to move upward. When the third spring 708 is subjected to an upward pulling force, the third spring 708 will be stretched and deformed, and at the same time, the third spring 708 will apply an upward pulling force to the side frame 703. Since the side frames 703 on both sides are in a clamping state with the plug body 605, the side frames 703 will also synchronously apply an upward pulling force to the plug body 605 when the force is applied. At this time, the plug body 605 is pulled up for connection strength testing through the pulling force of the side frames 703. As the pull rod 711 continues to move, its height will gradually rise as the pull rod 711 moves along the path of the first inclined plate 803 and the second inclined plate 806. Therefore, the pull rod 711 will gradually apply a greater pulling force to the plug body 605, that is, the side frames 703 will apply a linear pulling force to the plug body 605. The rising pulling force realizes the connection strength detection. While the side frame 703 applies an upward pulling force to the plug body 605, the side frame 703 applies an upward pulling force to the first spring 607 through the connection between the second spring 702 and the partition frame 701. Then the pull rod 711 continues to move away from the first inclined plate 803 and the second inclined plate 806. After the bottom of the pull rod 711 loses the support of the second inclined plate 806, the rebound force of the third spring 708 can drive the supporting plate 709, the frame rod 710 and the pull rod 711 to move down and reset. At this time, the supporting plate 709 drives the first magnetic plate 712 to move downward. After the first magnetic plate 712 moves downward, it fits and is adsorbed on the second magnetic plate 714, so as to limit and fix the position of the supporting plate 709. The side frame 703 is displaced to the position of the guide block 9 on the other side, and the roller 707 contacts the inclined surface of the guide block 9 and moves outward. At this time, the rebound force of the second spring 702 is used to drive the side frame 703 to move outward and reset. After the side frame 703 moves, it is disengaged from the clamping of the plug body 605. The staff can directly take out the plug body 605 to complete the connection strength test. For the strength test operation of the plug body 605, after the staff inserts the plug body 605 into the socket 604 and completes the connection with the connecting seat 603, the conveyor belt 5 is driven to operate by the motor 2. After the connecting seat 603 moves to the clamping block 10, the displacement of the roller 707 can be used to drive the side frame 703 to move and clamp the plug body 605.The pull rod 711 moves along the first inclined plate 803 and the second inclined plate 806 to apply a linearly increasing pulling force to the plug body 605 to achieve connection strength detection. After the roller 707 continues to move, it will be separated from the clamping block 10 and release the clamping of the plug body 605, thereby realizing the automatic detection operation of the plug body 605.
