For example, a chute is provided inside the base 2 along its length, a plurality of locking holes 201 are opened in the base 2 in the horizontal direction, the locking holes 201 are circular holes, and the plurality of locking holes 201 are arranged in a line, and a rail hole 202 is opened in the base 2 in the horizontal direction opposite the plurality of locking holes 201, and the rail hole 202 is a rectangular hole having a predetermined length, and both the plurality of locking holes 201 and the rail hole 202 communicate with the chute inside the base. The sliding lever member 4 has a mounting cavity, and further includes a locking base 61, a fifth spring 62, a stopper 63 and a mounting cavity cover 64 that are mounted in the mounting cavity. The locking hole 201, the locking base 61, the rail hole 202 and the stopper 63 are provided in one-to-one correspondence. The stopper 63 is provided at the bottom of the mounting cavity. The fifth spring 62 is provided between the locking base 61 and the stopper 63 to form an elastic support for the locking base 61 and the stopper 63. As a result, the sliding lever member 4 is able to slide left and right. The mounting cavity lid 64 is provided above the locking base 61 and is fixed to the sliding lever member 4 via a screw, the top of the locking base 61 is an arc-shaped or hemispherical structure, the top of the locking base 61 extends through the mounting cavity lid 64 into the locking hole 201, the stopper 63 extends through the bottom of the mounting cavity into the rail hole 202, and when the stopper 63 slides until it contacts either end of the rail hole 202, it reaches the maximum stroke or initial position for adjusting the sliding lever member 4 in the side headless 1 left and right.

[0031] In this way, when a user needs to adjust the spacing distance between two side headless units 1, he or she pushes or pulls the side headless unit 1, causing the sliding lever member 4 in the side headless unit 1 to slide left or right in the chute inside the base 2, disengaging the locking base 61 from the locking hole 201, and compressing and deforming the fifth spring 62. When the sliding lever member 4 slides left or right until the locking base 61 is locked into the corresponding locking hole 201, a locked state is formed against the left and right sliding of the sliding lever member 4 under the restoring elastic supporting force of the fifth spring 62, preventing the side headless unit 1 from sliding freely and affecting the user's experience.

[0032] As described above, the present invention is provided with two hook assemblies 3 that can be adjusted left and right, and can realize the adjustment of the distance between the two U-shaped clamping openings of the two hook assemblies 3, so that it can be applied to car seats of different sizes.
