The positioning unit 1 positions the brake hose 10 and the fitting 20 along the axis, and the brake hose 10 can still rotate relative to the fitting 20.
Two groups of phase angle adjusting units 2 are also arranged and are respectively connected with the two locking units 1. During adjustment, one of the phase angle adjusting units 2 may be adjusted, or two of the phase angle adjusting units 2 may be adjusted at the same time, and the phase angle adjusting unit 2 is used to adjust the phase angle between two fittings 20. Since the hardware 20 is fixedly connected with the locking unit 1, the phase angle adjusting unit 2 adjusts the phase angle of the hardware 20 by adjusting the phase angle of the locking unit 1.
The length adjusting unit 3 is connected with the two phase angle adjusting units 2, and adjusts the length between the two fittings 20 by adjusting the length between the two phase angle adjusting units 2. After the length and the phase angle are adjusted, the locking unit 4 locks the brake hose 10 and the fitting 20, so that the locking of the degrees of freedom of the length direction and the phase angle of the brake hose 10 and the fitting 20 is realized.
In the embodiment, two ends of the brake hose 10 are connected with the two hardware fittings 20 in a positioning manner through the positioning unit 1; then, the length between the two phase angle adjusting units 2 is adjusted through the length adjusting unit 3, namely, the length between the two hardware fittings 20 is adjusted; then, the phase angle between the two hardware fittings 20 is adjusted through the phase angle adjusting unit 2; and finally, the brake hose 10 is locked with the hardware fitting 20 by the locking unit 4.

Specifically, the positioning unit 1 includes a positioning flange 13, the positioning flange 13 is used for positioning the hardware fitting 20, the hardware fitting 20 extends into the positioning flange 13, the positioning flange 13 is coaxially connected with the hardware fitting 20, the large gear 23 is coaxially and fixedly connected with the positioning flange 13 through a bolt, and the large gear 23 is fixed on the adjusting housing 29 through a bearing (not shown).
The phase angle knob 21, the central shaft 26 and the pinion gear 22 are coaxially and fixedly connected, and the pinion gear 22 is meshed with the outer circumference of the large gear 23. The center shaft 26 is mounted on the adjustment housing 29 and is rotatable relative to the adjustment housing 29.
When the phase angle needs to be adjusted, the phase angle knob 21 is rotated, the phase angle knob 21 drives the small gear 22 to rotate through the central shaft 26, the small gear 22 drives the large gear 23 to rotate, the large gear 23 drives the positioning flange 13 to rotate, and the positioning flange 13 drives the hardware fitting 20 to rotate, so that the phase angle of the hardware fitting 20 is adjusted. Because the small gear 22 drives the big gear 23 to adjust the angle, the adjusting range is ensured to have larger operation space.

In some embodiments of the present invention, as shown in fig. 3 to 4, the phase angle adjusting unit 2 further includes a self-locking feedback assembly, the self-locking feedback assembly includes a swing link 24 and a plurality of protrusions 25, one end of the swing link 24 is movably connected with a central shaft 26 of the phase angle knob 21, the plurality of protrusions 25 are uniformly spaced around the central shaft 26 to form at least one circle, and the swing link 24 is in contact with the protrusions 25;
when the phase angle knob 21 rotates, the swing rod 24 is driven to rotate together through the central shaft 26, the swing rod 24 is sequentially contacted with the plurality of protrusions 25, so that the swing rod 24 swings back and forth along the direction of the central shaft 26, and when the phase angle knob 21 does not rotate and the swing rod 24 enters between two adjacent protrusions 25, the swing rod 24 is locked at the position.
Specifically, the swing link 24 extends from the central shaft 26 in a radial direction toward a circle formed by the plurality of protrusions 25, and one end of the swing link 24 may be rotatably connected to the central shaft 26 or swing up and down. The other end of the swing link 24 contacts the protrusion 25.
The plurality of protrusions 25 can form at least one circle, and the adjacent protrusions 25 are arranged at intervals, so that the other end of the swing rod 24 can fall into the gap between the adjacent protrusions 25.

By analogy, the swing rod 24 is driven to swing or jump up and down continuously on the circle formed by the protrusion 25 along with the continuous rotation of the phase angle knob 21. The swing rod 24 reminds the user that the phase angle is adjusted by one time when jumping once, and the phase angle is used for feeding back the adjustment angle of the phase angle. The size of the adjustment angle of one scale of the phase angle is realized by setting the size of the gap between the bulges 25, and the adjustment function of high precision and feedback is achieved.

The diameter of the coarse adjustment ring set formed by the first protrusions 251 is smaller than that of the fine adjustment ring set formed by the second protrusions 252.
When the oscillating bar 24 contacts with the first protrusion 251, the adjustment angle of the phase angle of each rotation is larger, and the adjustment precision is lower; when the swing rod 24 is in contact with the second protrusion 252, the adjustment angle of the phase angle of each rotation is small, and the adjustment precision is high.
