The push plate 64 and the transmission rod 62 are also connected through the connecting protrusion 63. A telescopic rod 65 is arranged on the other side of the push plate 64.

[0031] When in use, the telescopic rod 65 is controlled to retract so that the transmission rod 62 is turned inward with the connecting protrusion 63 on the surface of the push plate 64 as the center, thereby pulling the clamping plate 61 at the other end to turn outward with the slider 510 as the center to open and close. After the device is aligned with the clamping target, the telescopic rod 65 is controlled to retract, pushing the transmission rod 62 to turn outward with the connecting protrusion 63 on the surface of the push plate 64 as the center, thereby driving the clamping plate 61 at the other end to turn inward with the slider 510 as the center to close and achieve stable clamping of the target.

[0032] The adjustment mechanism 5 includes a positioning block 51 and a slide groove 52. The positioning block 51 is symmetrically provided with the slide groove 52 inside. The slide groove 52 is provided with a change rod 53 inside. An idle bearing seat 54 is provided on one side of the change rod 53. An adjustment knob 55 is provided on the other side of the change rod 53. A slider 510 is provided on the outside of the change rod 53. A through hole 511 is provided inside the slider 510.

A sliding adjustment groove 58 is provided on the outside of the adjustment rod 56. By rotating the fixing bolt 59, the adjusting rod 56 can be adjusted along the sliding adjusting groove 58, and then the adjusting knob 55 is rotated, so that the adjusting knob 55 drives the changing rod 53 to rotate, and cooperates with the thread of the internal through hole 511 of the slider 510 to move, thereby driving the clamping plate 51 to move in the same direction along the sliding groove 52, so that the clamping plate 61 can clamp more tightly, thereby effectively avoiding the problem that some smaller or irregular clamping targets are easy to fall off, enhancing the adaptability of the device, and at the same time can reduce the opening and closing angle of the device for clamping the target, and can avoid affecting the surrounding targets when clamping smaller targets.

[0033] A mounting plate 3 is provided on one side of the driving motor 1, a limiting frame 2 is provided on one side of the mounting plate 3, an opening 4 is provided inside the limiting frame 2, and the combined shape of the limiting frame 2 and the opening 4 is a C shape; the sliding direction of the push plate 64 is limited by the combined shape of the limiting frame 2 and the opening 4.

[0034] The inside of the through hole 511 and the outside of the changing rod 53 are both provided with threads, and connecting protrusions 63 are provided on both sides of the slider 510.

The connecting protrusion 63 is fixedly connected to the splint 61, and the transmission rod 62 is sleeved on the outer side of the connecting protrusion 63. The arc-shaped groove of the splint 61 increases the wrapping degree of irregular targets, thereby enhancing the adaptability of the device.

[0036] The idle bearing seat 54 is fixedly connected to the slide groove 52 , and the adjusting knob 55 passes through the slide groove 52 and one side surface of the positioning block 51 ; the idle bearing seat 54 allows the adjusting rod 56 to idle in the slide groove 52 .

[0037] The transmission rod 62 is in a Y-shape, and the telescopic rod 65 is electrically connected to the driving motor 1 . The driving motor 1 controls the extension and retraction of the telescopic rod to drive the clamping plate 61 to clamp the target.

[0038] Working principle: Before use, connect the device to the power supply to ensure that the device can be used normally; when in use, adjust the clamping opening and closing angle of the device according to the target to be clamped, and by rotating the fixing bolt 59, allow the adjustment rod 56 to be adjusted along the sliding adjustment groove 58, and then rotate the adjustment knob 55, so that the adjustment knob 55 drives the change rod 53 to rotate, and cooperates with the thread of the internal through hole 511 of the slider 510 to move, thereby driving the clamping plate 51 to move in the same direction along the sliding groove 52, so that the clamping plate 61 is clamped more tightly, thereby effectively avoiding the problem that some smaller or irregular clamping targets are easy to fall off, and enhancing the adaptability of the device. , and at the same time, it can reduce the opening and closing angle of the device for clamping the target, and can avoid affecting the surrounding targets when clamping smaller targets; when clamping, the telescopic rod 65 is controlled to contract so that the transmission rod 62 is turned inward with the connecting protrusion 63 on the surface of the push plate 64 as the center, thereby pulling the clamping plate 61 at the other end to turn outward with the slider 510 as the center to open and close. After the device is aligned with the clamping target, the telescopic rod 65 is controlled to contract, and the transmission rod 62 is pushed to turn outward with the connecting protrusion 63 on the surface of the push plate 64 as the center, thereby driving the clamping plate 61 at the other end to turn inward with the slider 510 as the center to close, thereby achieving stable clamping of the target.
