[0035] The present utility model provides a universal free-rotating telescopic fixed arm, which can be applied to a detection device. Figure 1 And Figure 2 shows a preferred embodiment of the universal free-rotating telescopic fixed arm provided by the present utility model. Figure 3 And Figure 4 shows a preferred embodiment of the application of the universal free-rotating telescopic fixed arm provided by the present utility model to a detection device.

[0036] Please refer to Figure 1 AndFigure 2 , in this embodiment, the universal freely rotatable and telescopic fixing arm 100 has a fixed end 1 and a free end 2 opposite to each other in the length direction. The universal freely rotatable and telescopic fixing arm 100 includes a steering structure 3 and a first connecting member 4. The steering structure 3 includes an adjusting screw member 31, two spherical bodies 32 and two steering connecting plates 33. The two spherical bodies 32 are spaced opposite to each other in the length direction, and the two spherical bodies 32 are clamped between the two steering connecting plates 33. Each steering connecting plate 33 is provided with two rotating grooves 34 respectively rotatably engaged with the two spherical bodies 32. The adjusting screw member 31 is located between the two spherical bodies 32. The tail of the adjusting screw member 31 passes through one steering connecting plate 33 and is threadedly connected to the other steering connecting plate 33. A plurality of steering structures 3 are arranged at intervals along the length direction; the first connecting member 4 is arranged to extend along the length direction, and a first connecting member 4 is arranged between two adjacent spherical bodies 32 that are close to each other in any two steering structures 3, so that the free end 2 can be adjusted relative to the fixed end 1.

[0037] Specifically, please refer to Figure 3 and Figure 4 , the detection device 1000 includes a device main body 200 and a detection device 300. The device main body 200 can be a detection table or the like, and the detection table is used to carry the product to be detected. The fixed end 1 of the universal freely rotatable and telescopic fixing arm 100 is fixedly arranged on the device main body 200. The detection device 300 can be a CCD camera or the like, and the detection device 300 is arranged at the free end 2 of the universal freely rotatable and telescopic fixing arm 100, so that it can be correspondingly placed on the product to be detected on the device main body 200, and the detection angle of the detection device 300 is adjusted through the universal freely rotatable and telescopic fixing arm 100.

[0038] The universal freely rotatable and telescopic fixed arm 100 includes a plurality of steering structures 3. The plurality of steering structures 3 are sequentially connected by a first connecting member 4. Each steering structure 3 includes two steering connecting plates 33 spaced opposite to each other in a direction perpendicular to the length direction. The two steering connecting plates 33 are connected by an adjusting screw member 31. Two spherical bodies 32 are clamped between the two steering connecting plates 33. After tightening the adjusting screw member 31, the two spherical bodies 32 will not fall off between the two steering connecting plates 33. Since each steering connecting plate 33 is provided with two rotating grooves 34 respectively in rotational cooperation with the two spherical bodies 32, each spherical body 32 on the universal freely rotatable and telescopic fixed arm 100 can rotate, so as to realize adjusting the detection angle of the detection device 300 through the universal freely rotatable and telescopic fixed arm 100. And because there are a plurality of steering structures 3 and each steering structure 3 includes two spherical bodies 32, the detection angle of the detection device 300 can be adjusted by rotating the spherical bodies 32 at multiple positions of the universal freely rotatable and telescopic fixed arm 100, thus facilitating the quick adjustment of the detection angle of the detection device 300 and having strong flexibility. Among them, the adjusting screw member 31 can be an adjusting nut, etc., and the first connecting member 4 can be arranged in a rod shape, etc.

[0039] The steering connecting plate 33 is provided with a rotating groove 34 in rotational cooperation with the spherical body 32. The rotating groove 34 can be a circular groove or a conical groove, etc. Optionally, please refer to Figure 1 and Figure 2 , in this embodiment, the rotating groove 34 is a circular groove.

[0040] The rotating groove 34 can be through or non-through the surface of the steering connecting plate 33 away from the spherical body 32. Optionally, please refer to Figure 1 and Figure 2 , in this embodiment, the rotating groove 34 penetrates the steering connecting plate 33. The rotating groove 34 is arranged on the surface of the steering connecting plate 33 close to the spherical body 32, and the rotating groove 34 can be through the surface of the steering connecting plate 33 away from the spherical body 32.

[0041] When the spherical body 32 and the rotating groove 34 in the steering structure 3 are worn and the spherical body 32 between the two steering connecting plates 33 becomes loose, the adjusting screw member 31 in this steering structure 3 can be tightened to make the two steering connecting plates 33 clamp the spherical body 32 again, so that the universal freely rotatable and telescopic fixed arm 100 can still continue to be used normally.

[0042] When the detection device 300 is arranged at the free end 2 of the universal free-rotating telescopic fixing arm 100, by rotating a spherical body 32 in any one of the steering structures 3, the detection angle of the detection device 300 can be adjusted. Since there are multiple steering structures 3 and each steering structure 3 includes two spherical bodies 32, it is convenient to quickly adjust the detection angle of the detection device 300. And when the spherical body 32 in a certain steering structure 3 and the rotating groove 34 are worn, by tightening the adjusting screw connector 31 in this steering structure 3, the universal free-rotating telescopic fixing arm 100 can still continue to be used normally. The universal free-rotating telescopic fixing arm 100 has the advantages of being strong and durable, flexible, low-cost, and long service life.
