[0030] Secondly, the rotating assembly 5 is installed at the connection between one end of the installation beam seat 1 and the support pipe 2, the rotating assembly 5 includes a limiting plate 52 and a connecting plate 54, and both are fixedly installed on the installation beam seat 1 and the support pipe 2 respectively, the limiting plate 52 and the connecting plate 54 are rotationally connected through a rotating shaft 521, so that the support pipe 2 and the installation beam seat 1 can rotate around the rotating shaft 521 by a certain angle, thereby controlling the inclination angle of the support pipe 2, after the support pipe 2 is rotated and inclined according to the actual use scene, the opening of the trunk can be avoided to cause obstruction, a "W" shaped limiting clamping groove 53 is opened at the edge of the limiting plate 52, a control handle 55 is rotationally connected outside the connecting plate 54, one end of the control handle 55 is fixed with a limiting clamping shaft 542, and the limiting clamping shaft 542 is clamped into the inner cavity of the limiting clamping groove 53, as Figure 3 and Figure 1 As shown, the user can separate the limiting clamping shaft 542 from the groove at one end of the limiting clamping groove 53 by stepping on the other end of the control handle 55, at this time, the support pipe 2 and the connecting plate 54 can rotate around the rotating shaft 521 to change the included angle between the support pipe 2 and the installation beam seat 1, when the limiting clamping shaft 542 rotates and slides in the inner cavity of the limiting clamping groove 53 to the groove at the other end of the limiting clamping groove 53, it cannot continue to move, at this time, the support pipe 2 remains in an inclined state of about forty-five degrees, that is, an included angle of about one hundred and thirty-five degrees is formed between the support pipe 2 and the installation beam seat 1, so that the bracket 3 at the upper end of the support pipe 2 will not collide with the ground and the user's body due to the rotation angle of the support pipe 2 being too large;

[0031] Furthermore, the bracket 3 is rotatably connected to the support tube 2, and a folding component 6 is provided at the connection point to position the bracket 3. The bracket 3 is U-shaped and is provided with a positioning buckle 4 to fasten the bicycle. After the bracket 3 is rotated and unfolded to a horizontal state, the folding component 6 positions the bracket 3. At this time, the bicycle is placed on the bracket 3 and the positioning buckle 4 is used to fasten and fix the bicycle frame, so that the bicycle can be suspended and installed at the rear of the car.

[0032] To prevent the limiting pin 542 from completely disengaging from the limiting slot 53, this application also features an arc-shaped groove 541 extending through the surface of the connecting plate 54, with the limiting pin 542 movably passing through the inner cavity of the arc-shaped groove 541. The middle part of the control handle 55 is rotatably mounted on the side of the connecting plate 54 via a shaft. Figure 3 As shown, the arc-shaped groove 541 is used to limit the travel of the limiting pin 542. When the limiting pin 542 moves, it can disengage from the groove at one end of the limiting slot 53, but it will not completely disengage from the limiting slot 53. In other words, the limiting slot 53 can always limit the movement path of the limiting pin 542, thereby avoiding the support tube 2 from rotating and tilting too much. That is, the maximum tilt angle of the support tube 2 is forty-five degrees.

[0033] To tighten the limiting pin 542, this application further includes a tension spring 543 disposed between the rotating shaft 521 and the limiting pin 542, with both ends of the tension spring 543 respectively sleeved on the rotating shaft 521 and the limiting pin 542. The middle part of the limiting groove 53 is arc-shaped, and its center coincides with the rotating shaft 521. The center of the arc-shaped groove 541 coincides with the axis of the middle part of the control handle 55. Figure 3 As shown, the tension spring 543 is used to pull the limit pin 542, so that the limit pin 542 always tends to move closer to the rotation axis 521. Therefore, when the user does not step on the control handle 55, the limit pin 542 can automatically lock into the groove at one end of the limit slot 53, ensuring that the support tube 2 remains stably vertical.

[0034] In order to protect the components on the rotating assembly 5, this application also has a housing 51 fixed at the lower end of the support tube 2, and the housing 51 covers the outside of the connecting plate 54. The limiting plate 52 is movably inserted into the middle of the inner cavity of the housing 51. The housing 51 is provided to protect the various components at the connection between the mounting beam seat 1 and the support tube 2, thereby improving the overall service life of the device.

The positioning clamp 62 is a two-half structure and is fixedly connected by bolts, which is mainly used for installing and positioning the bracket 3, so that the bracket 3 can only rotate around the middle part of itself and cannot be shifted in position. A limiting support 63 is fixed on one side of the positioning clamp 62, and the limiting support 63 and the support pipe 2 are both provided with a positioning insertion hole. The middle part of the bracket 3 is fixedly provided with a butt plate 64, one end of the butt plate 64 is provided with a pin shaft 65, the pin shaft 65 inserts and fixes the butt plate 64 with one positioning insertion hole, and the pin shaft 65 is connected with the other positioning insertion hole. Figure 4 And Figure 5 As shown in the figure, after the pin shaft 65 is pulled out, the butt plate 64 is no longer positioned, at this time the bracket 3 and the butt plate 64 can rotate freely, so as to realize the folding storage or unfolding of the bracket 3; when the bracket 3 rotates to a horizontal or vertical state, the butt plate 64 rotates and moves accordingly, so as to correspond to the positioning insertion hole on the support pipe 2 and the positioning insertion hole on the limiting support 63 respectively, at this time the pin shaft 65 is inserted again to position the butt plate 64, thereby realizing the positioning of the bracket 3 and avoiding the continuous rotation of the bracket 3.

[0036] In order to tighten the bicycle frame, the present application also has a support seat 31 fixedly installed on the outer side of the bracket 3 by bolts. The positioning buckle 4 is of flexible structure and is provided with a rack on the surface. The positioning buckle 4 is in the shape of "η" and can be used to tighten and fix the bicycle frame. The clasp 32 is rotatably installed on the side surface of the support seat 31. One end of the positioning buckle 4 is connected with the support seat 31, the other end is inserted through the gap between the support seat 31 and the clasp 32 and is clamped by the clasp 32 on the tooth groove on the surface of the positioning buckle 4. The rotating connection between the clasp 32 and the support seat 31 is provided with a torsional spring for resetting. As shown in the figure, by pulling the clasp 32, the clamping of the tooth groove on the positioning buckle 4 can be released, at this time the other end of the positioning buckle 4 can be freely pulled out. After the clasp 32 is loosened, the clasp 32 is automatically clamped and positioned on the positioning buckle 4 under the action of the torsional spring, thereby avoiding the loosening of the tightening of the positioning buckle 4 on the bicycle frame. Figure 6

[0037] In order to further wind and bind the bicycle, the present application also has a cladding layer 7 provided on the middle outer side of the support pipe 2, which is used to avoid the strong collision between the bicycle and the support pipe 2 after the bicycle is hung, so as to avoid the damage of the bicycle or the device.
