7. The trim of claim 1 , wherein the trim is provided with at least one tear line, the tear line is parallel to the length direction of the trim, and the trim is configured to be able to be broken along the tear line under the action of an external force.

8. The trim of claim 1 , wherein the trim is configured that when the first side edge and the second side edge come into contact with the vertical beam, the distance between the first side edge and the second side edge changes, thereby the first side edge and the second side edge are clamped on the vertical beam.

9. The trim of claim 1 , wherein the trim is flexible, and the trim is configured to be able to be rolled up to form a cylinder.

10. A vertical beam assembly, comprising:

a vertical beam which comprises a front panel and two side surfaces, wherein the two side surfaces are respectively located on two opposite sides of the front panel along its length direction, such that the cross-section of the vertical beam is U-shaped; and

a trim which is covered on at least part of the surface of the vertical beam, wherein the trim is configured such that by using a force generated by contact between the trim and the vertical beam, the trim is fixed on the vertical beam;

wherein

the trim comprises a body, the body is in a long strip shape, the shape of the body is matched with a front panel, with slotted holes, of the vertical beam, and the body is configured to be covered on the front panel of the vertical beam;

the trim further comprises a first side edge and a second side edge, the first side edge and the second side edge are respectively connected to two opposite sides of the body along its length direction, the first side edge and the second side edge protrude outward from the body, and a distance between the first side edge and the second side edge is less than a width of the vertical beam in an original state, and the first side edge and the second side edge are configured such that the distance between the first side edge and the second side edge changes under an action of an external force, and the distance returns to the original state when the external force disappears; and

the trim further comprises suction components, wherein when the suction components come into contact with the vertical beam, the suction components are pressed to squeeze out air, thereby forming a negative pressure to fix the trim on the vertical beam;

wherein the body of the trim is provided with the suction components, and the suction components are suction cups;

wherein the first side edge and the second side edge of the trim are provided with a plurality of projecting magnetic portions made of magnetic materials.
