[0023] The present invention has the following beneficial effects:

[0024] When this invention is used, the position is first determined. At this time, the power device inside the lifting component is activated, driving the output telescopic rod to move. The output telescopic rod then drives the locking rod to move, which in turn drives the lifting hydraulic rod to move. The lifting hydraulic rod then drives the pressure rod slide along the inner wall of the pressure plate slider, eventually reaching the desired position. Simultaneously, when the locking rod drives the lifting hydraulic rod, the lifting hydraulic rod also drives the horizontal slot plate to move, which in turn drives the arc plate to move. When the arc plate moves, it drives the oblique telescopic rod to move, which in turn drives the connecting plate to move. When the connecting plate moves, it drives the inner telescopic rod to move. At the same time, the lifting hydraulic rod is activated, pushing the horizontal slot plate up and down, ultimately driving the inner telescopic rod to move. Meanwhile, the control plate controls the external threaded rod to rotate, which drives the fixed rod to move up and down. When the fixed rod moves, it drives the spring pressure plate to move elastically. At the same time, the spring pressure plate provides auxiliary fixing through reaction force.

[0025] When this invention is in use, the motor inside the rotating component starts, driving the rotating output rod to rotate. The rotating output rod then drives the rotating horizontal plate to move. When the rotating horizontal plate moves, it drives the rotating column plate to move along the surface of the connecting column plate. At the same time, when the rotating column plate rotates, it drives the fixed block to move. The fixed block then drives the fixed shaft to move. The fixed shaft then drives the bidirectional spring plate to move. When the bidirectional spring plate moves, it drives the arc-shaped locking plates and support plates at both ends to move, eventually rotating to the desired position. Meanwhile, when using the device, when the required joint is placed into the device and placed on the surface of the arc-shaped locking plate, it pushes the arc-shaped locking plate to move. The arc-shaped locking plate then drives the locking plate telescopic rod to move along the inner wall of the telescopic rod groove, eventually fixing the joint in the desired position. At the same time, when the rotating output rod moves, it drives the rotating output rod behind it through the universal joint. The support plate drives the support plate behind it to move simultaneously through the tension connecting column.

[0026] When this invention is in use, once the angle adjustment component is fixed in position, it drives the output rod to rotate. The output rod then drives the output belt and transmission belt to move, which in turn drives the spring-loaded shaft on the inner wall of the other end to rotate along the inner wall of the transverse groove plate. When the spring-loaded shaft is running, it drives the rotating rope to run, which in turn drives the connecting slide rod to run. When the connecting slide rod is running, it drives the column rod groove plate to run, which in turn pulls the rotating column plate to adjust the angle. At the same time, when the connecting slide rod is running, it drives the needle rod connecting rod to run, which in turn drives the inner ruler needle rod to rotate along the surface of the transverse axis. By observing the contact between the other end of the inner ruler needle rod and the surface of the inner ruler plate, it can be observed whether the angle is adjusted correctly. Meanwhile, when the other spring-loaded shaft rotates, it will eventually drive the outer ruler needle rod to rotate along the surface of the transverse axis, and the adjusted angle can be observed.

[0027] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The needle bar connecting rod 73 will drive the inner ruler needle bar 69 to rotate along the surface of the transverse axis 66. By observing the contact between the other end of the inner ruler needle bar 69 and the surface of the inner ruler plate 68, we can observe whether the angle is adjusted correctly. At the same time, when the other spring-loaded shaft 64 rotates, it will eventually drive the outer ruler needle bar 70 to rotate along the surface of the transverse axis 66.
