The first longitudinal luggage rack bar 7 is provided with one. The front side of the inner side of the first longitudinal luggage rack bar 7 is movably connected with a forward and reverse screw rod 8 through an axle pin. The back of the forward and reverse screw rod 8 extends to the right side of the back side of the transverse luggage rack bar 2. A second longitudinal luggage rack bar 9 is arranged on the left side of the first longitudinal luggage rack bar 7. The top of the second longitudinal luggage rack bar 9 and the top of the first longitudinal luggage rack bar 7 are fixedly connected with a limited support component 10, and movable components 11 are inlaid on both sides of the bottom of the inner wall of the movable groove 4.
[0023] refer to Figure 1 and Figure 2 The limiting support assembly 10 includes a limiting bar 101, the bottom of which is fixedly connected to the top of the first longitudinal luggage rack bar 7 and the top of the second longitudinal luggage rack bar 9, and limiting grooves 102 are provided on both sides of the bottom of the transverse luggage rack bar 2, and the inner wall of the limiting groove 102 is slidably connected to the surface of the limiting bar 101, and the cross-sections of the limiting groove 102 and the limiting bar 101 are both T-shaped.
[0024] As a technical optimization scheme of the utility model, by setting a limit support assembly 10, the user can utilize the sliding cooperation between the limit groove 102 and the limit bar 101 during the longitudinal adjustment process, so as to limit the rotation of the transverse luggage rack bar 2, thereby preventing the transverse luggage rack bar 2 from rotating during the transmission process, thereby improving the stability during the adjustment process, and at the same time, the limit bar 101 can be used to support the transverse luggage rack bar 2.

[0027] refer to Figure 3 A rotating rod 12 is fixedly connected to the back of the forward and reverse screw rods 8. The back of the rotating rod 12 penetrates into the back of the first longitudinal luggage rack bar 7 and is movably connected to the first longitudinal luggage rack bar 7. A limiting ring 13 is fixedly sleeved on the rear side of the surface of the rotating rod 12, and a hexagonal groove 14 is opened on the back of the rotating rod 12.
[0028] As a technical optimization scheme of the utility model, by setting the rotating rod 12, the limiting ring 13 and the hexagonal groove 14, when the user needs to rotate the forward and reverse screw rods 8, the user can use the hexagonal wrench whose model matches the hexagonal groove 14 and insert it into the hexagonal groove 14, and then rotate the hexagonal wrench to drive the rotating rod 12 to rotate, so that the rotating rod 12 drives the forward and reverse screw rods 8 to rotate. During the use of the forward and reverse screw rods 8, the limiting ring 13 can be used to limit the maximum activity space of the horizontal luggage rack bar 2 to avoid separation from the forward and reverse screw rods 8.

The magnetic plate 15 is then set in a hexagonal shape to make the magnetic plate 15 more fit the shape of the hexagonal wrench.
[0031] refer to Figure 2 A knob 16 is fixedly connected to the top of the stud 6, and the knob 16 is arranged in a cross shape.
[0032] As a technical optimization solution of the utility model, by setting the knob 16, when the user needs to rotate the stud 6, the user can directly rotate the knob 16 to rotate the stud 6, giving the user a point of force for applying force. The knob 16 is then arranged in a cross shape, which makes it convenient for the user to hold the knob 16 with his hand to apply force and avoid slipping.
[0033] refer to Figure 2 The top of the knob 16 is fixedly connected with an anti-lost rope 17 , and one end of the anti-lost rope 17 away from the knob 16 is fixedly connected to the outer side of the locking clamp body 1 .
[0034] As a technical optimization solution of the utility model, by providing an anti-lost rope 17, the user can directly place the stud 6 at will when rotating and unscrewing the stud 6, and then the stud 6 can be prevented from being lost under the action of the anti-lost rope 17, thereby improving the use efficiency of the stud 6.
[0035] The working principle and use process of the utility model are as follows: when the user needs to adjust the longitudinal spacing of the locking clamp body 1, the user can rotate the forward and reverse screw rods 8 so that the forward and reverse screw rods 8 drive the transverse luggage rack bar 2 to move inward or outward, thereby adjusting the longitudinal spacing of the locking clamp body 1, and in the adjustment process, the limiting groove 102 is used to slide with the limiting bar 101, so that the transverse luggage rack bar 2 can be rotationally limited, thereby preventing the transverse luggage rack bar 2 from rotating during the transmission process, thereby improving the stability of the adjustment process, and when the user needs to adjust the transverse spacing of the locking clamp body 1, the user can directly rotate the stud 6 so that the stud 6 is no longer threadedly connected to the screw hole 5, and then the user can directly slide The locking clamp body 1 moves laterally so that the lateral spacing between the locking clamp bodies 1 is adjusted. After the adjustment is completed, the user can directly use the stud 6 to thread the locking clamp body 1 with the corresponding screw hole 5. Then the user can position the adjusted locking clamp body 1. In the process of sliding the locking clamp body 1, the ball 111 can greatly reduce the friction between the locking clamp body 1 and the horizontal luggage rack bar 2, preventing the locking clamp body 1 from sliding and causing excessive friction with the horizontal luggage rack bar 2 to affect the adjustment efficiency. By setting the sliding arc groove 112, the top of the ball 111 is more closely attached to the horizontal luggage rack bar 2, further reducing the friction, and having the ability of longitudinal and lateral adjustment.
[0036] To sum up: the locking clamp of the car luggage rack is provided with a forward and reverse screw rod 8, and the forward and reverse screw rod 8 is rotated to drive the longitudinal spacing of the locking clamp body 1 to be adjusted. When the user needs to adjust the lateral spacing of the locking clamp body 1, the locking clamp body 1 is directly slid to move laterally, so that the lateral spacing between the locking clamp bodies 1 is adjusted, which solves the problem that only the horizontal spacing of the locking clamp can be adjusted. When the cargo with special shapes needs to be tilted and positioned when being transported, the locking clamp cannot match the cargo with special shapes for positioning and clamping, thereby reducing the use effect.
