The connecting pipe 3 and the fixing plate 42 will move synchronously. A motor 43 is provided on the left surface of the positioning plate 41. The motor 43 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The output shaft of the motor 43 is fixedly connected to a rotating shaft 44. The middle section of the outer wall of the rotating shaft 44 is fixedly connected to a gear 45. Starting the motor 43 can drive the rotating shaft 44 and the gear 45 to rotate.

[0032] Reference Figure 1 - Figure 3 The length adjustment assembly also includes a threaded rod 47. The threaded rod 47 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The threaded rod 47 is self-locking. The right end of the outer wall of the threaded rod 47 is fixedly connected to the gear 2 46, and the threaded rod 47 and the gear 2 46 will rotate synchronously.

[0033] Reference Figure 1 - Figure 3 The angle adjustment assembly includes a support plate 51, a circular ring 52 is fixedly connected to the lower surface of the positioning plate 41, an annular groove 501 is provided on the upper surface of the support plate 51, the circular ring 52 and the annular groove 501 are matched, and a limiting groove 502 is provided on the upper surface of the support plate 51.

The lower surface of the shift block 53 is fixedly connected to a round block 55, and the lower surface of the round block 55 is fixedly connected to a limiting block 56.

[0034] Reference Figure 1 - Figure 3The rotating shaft 44 passes through and is rotatably connected to the left surface of the positioning plate 41 , and the positioning plate 41 provides support for the rotating shaft 44 .

[0035] Reference Figure 1 - Figure 3 The threaded rod 47 passes through and is threadedly connected to the left surface of the fixed plate 42. When the threaded rod 47 rotates, it will drive the fixed plate 42 to move horizontally. When the threaded rod 47 stops rotating, the fixed plate 42 will be fixed in the current position under the influence of the self-locking property of the threaded rod 47. The threaded rod 47 passes through and is rotatably connected to the left surface of the positioning plate 41. Gear 2 46 and gear 1 45 are meshed. When gear 1 45 rotates, it will drive gear 2 46 to rotate.

[0036] Reference Figure 1 - Figure 3 The ring 52 is slidably connected to the inner wall of the annular groove 501, and the lower surface of the support plate 51 is fixedly connected to the upper surface of the flange 1. When the ring 52 slides in the annular groove 501, it will drive the positioning plate 41 to rotate, and the angle of the flange 1 will appear tilted.

[0037] Reference Figure 1 - Figure 3 The limiting groove 502 is opened in the shape of a gear, the shift block 53 passes through and is slidably connected to the right surface of the positioning plate 41, sliding longitudinally, one end of the compression spring 54 is fixedly connected to the inner wall at the top of the positioning plate 41, and the other end of the compression spring 54 is fixedly connected to the upper surface of the shift block 53. When the shift block 53 moves upward, it will squeeze the compression spring 54 to generate a reaction force.

[0038] Reference Figure 1 - Figure 3 The limit block 56 is set to be gear-shaped, and the limit block 56 is plugged into the inner wall of the annular groove 501. The limit groove 502 is slightly larger than the limit block 56, which is convenient for plugging.

[0039] Working principle: When the length of the device needs to be adjusted, the motor 43 is started, and the motor 43 drives the rotating shaft 44 to rotate, thereby driving the gear 1 45 to rotate, and the gear 1 45 is meshed with the gear 2 46 to drive the gear 2 46 and the threaded rod 47 fixedly connected thereto to rotate. Since the threaded rod 47 is threadedly connected to the fixing plate 42, and the threaded rod 47 has a self-locking property, when the threaded rod 47 rotates, it will push the fixing plate 42 to move horizontally, and at the same time drive the connecting pipe 3 to move, and the connecting pipe 3 and the flange 1 are separated or approached, so as to drive the bellows 2 to stretch or contract, thereby completing the adjustment of the overall length of the device.

[0040] When the angle of the flange 1 needs to be adjusted, the shift block 53 is pushed upward, and the shift block 53 compresses the compression spring 54 and drives the round block 55 and the limit block 56 to move upward, so that the limit block 56 is disengaged from the limit groove 502. At this time, the positioning plate 41 can be rotated, and the positioning plate 41 slides in the annular groove 501 through the circular ring 52, thereby driving the flange 1 to rotate and change the angle. After the angle is adjusted, the shift block 53 is released, and under the reaction force of the compression spring 54, the limit block 56 is reinserted into the corresponding limit groove 502 to fix the angle of the flange 1.
