[0031] Specifically, the adjusting shaft 28 is installed in a closed space to protect the wire from pollution. Figure 2-Figure 4The angle valve seat 29 is mounted on the conduit 1. The angle valve seat 29 is provided with an identification panel, which is used to indicate the rotation angle of the adjustment shaft 28. The adjustment component 14 also includes an adjustment knob 31, a shaft cover 30 and an upper cover 32. The adjustment knob 31 is connected to the adjustment shaft 28 through the shaft cover 30 to play a supporting role. The upper cover 32 is installed on the angle valve seat 29 so that the adjustment shaft 28 is located in a closed space. Furthermore, in order to achieve the effect of fixing the position after adjusting the angle, the adjustment component 14 also includes a locking component. In this embodiment, the locking component includes a clamping structure provided on the shaft cover 30 and the angle valve seat 29, such as Figure 4 The shaft cover 30 is spline-connected to the adjusting shaft 28, a snap-fitting protrusion is provided on the shaft cover 30, and a snap-fitting groove is provided in the angle valve seat 29. In other embodiments, the adjusting knob 31 may also be provided with a plum blossom-shaped snap-fitting protrusion, and a corresponding snap-fitting groove is provided in the angle valve seat 29. When adjusting the angle, the adjusting knob 31 is pulled outward to disengage the snap-fitting protrusion from the snap-fitting groove, and the adjusting knob 31 is rotated to wind or loosen the wire to adjust the bending angle. After the adjustment is completed, the adjusting knob 31 is pressed back, and the snap-fitting protrusion cooperates with the snap-fitting groove to achieve locking.
[0032] In this embodiment, Figure 5 The adjusting structure includes an adjusting wire that passes through the snake bone block 26 in sequence and an adjusting block connected to the end of the adjusting wire, the wire is connected to the adjusting block, and the adjusting structure is provided with two groups, namely a left adjusting structure 27 and a right adjusting structure 25, which are connected to the two sides of the bending adjustment section 11 composed of a plurality of snake bone blocks 26, for realizing angle adjustment in two directions.
