Further, the steel wire rope assembly 4 comprises a plurality of steel wire ropes 41; each of the wire ropes 41 includes an outer tube 411; a pull cord 412 is arranged in the outer tube 411; the end part of the outer tube 411 is provided with a protection mechanism; the protection mechanism comprises a metal rivet 414 arranged at the end part of the outer tube 411; a plastic lining 415 is arranged on the inner side of the metal rivet head 414; the cable wire 412 is connected with the metal rivet 414 through the plastic bushing 415; in the invention, the outer tube 411 is clamped with the plastic bushing 415 and then riveted with the metal rivet 414; the pull wire 412 penetrates from the outer tube 411 and slides freely; the steel wire rope 41 is assembled on the glass lifter after being assembled, the steel wire rope 41 drives the glass bracket 201 to slide up and down, glass is assembled on the glass bracket 201, and the glass slides up and down along with the glass bracket 201, so that the glass is lifted; the invention rivets with the outer tube 411 by adding a metal rivet 414; the performance of the metal piece is little degraded at high temperature, and the outer tube 411 of the steel wire rope 41 cannot penetrate through the wire wheel cover 11 to fail in the durable process; meanwhile, in order to prevent the wire rope 41 and the metal rivet 414 from generating scraping abnormal sound, a plastic bushing 415 is additionally arranged between the metal head and the outer tube 411, so that the wire rope 41 is prevented from being in direct contact with the metal rivet 414; abnormal sound can be eliminated to a certain extent.

Further, in the present invention, when the wire rope assembly 4 includes two or more wire ropes 41, the wire ropes 41 arranged to intersect are provided with the wire winding clamp pipe 7 at the intersection; the winding clamp tube 7 comprises two arc clamping plates 71 which are distributed at intervals, and the two arc clamping plates 71 are connected through a connecting arc plate 72; based on such arrangement, in the subsequent use, the two arc-shaped clamping plates 71 are simultaneously clamped on the outer tube 411 of one steel wire rope 41; the connecting arc plate 72 is sleeved on the outer tube 411 of the other steel wire rope 41, so that the intersecting arrangement of the outer tubes 411 of the two steel wire ropes 41 can be realized based on the design; the invention plays a good binding role by arranging the wire clamping pipe 7, and avoids the messy arrangement between the two steel wire ropes 41.

It is obvious that the specific implementation of the present invention is not limited by the above-mentioned modes, and that it is within the scope of protection of the present invention only to adopt various insubstantial modifications made by the method conception and technical scheme of the present invention.
