[0019] The protrusions increase the contact area between the connecting member and the floor mounting groove, thereby improving the stability of the connection. The plurality of protrusions can more effectively prevent the connecting member from loosening in the mounting groove, increasing the friction between the protrusions and the floor. The downward protrusions can be embedded in the floor, increasing the grip of the connecting member on the floor, making the connection more secure. At the same time, the protrusions provide additional support and fixation, which helps to prevent deformation of the floor due to uneven stress during installation and use.
