All be connected with backup pad 21 on the inner wall of lid 10 both sides, be formed with the conflict step on the backup pad 21, the conflict step has the first step face of perpendicular to side apron inner wall and the second step face that is on a parallel with the side apron inner wall, be equipped with pulley 22 on the first step face, the second step face facing is equipped with buffer spacer 23.

The telescopic protection cover faces the slide rail and covers the slide rail, in the sleeved cover bodies 10, two cover bodies (namely, a first cover body 101 and a fourth cover body 104) at the outermost ends are respectively and fixedly connected with the processing platform and the outermost ends of the slide rail, and second step surfaces of abutting steps at two inner sides of the cover bodies 10 are matched with the two outer ends of the slide rail through buffer gaskets 23, so that the telescopic protection cover is not easy to dislocate; the first step surface of the abutting step is in sliding fit with the surface of the sliding rail through the pulley 22, so that the sliding fit is realized, and the abrasion to the sliding rail is small; the flexible cooperation between a plurality of lids 10 of flexible safety cover can be fine satisfy the slip of processing platform on the slide rail for flexible safety cover covers exposed slide rail all the time, effectively blocks the piece and spatters to the slide rail on, guarantees the cleanliness of slide rail.

Furthermore, in this embodiment, the side cover plates on both sides of the upper cover plate further extend inward to form an extension portion 11, so as to form a covering structure to cover and limit the other cover body 10 sleeved therein. So as to prevent the sleeved cover body 10 from separating and has simple structure. Of course, in other embodiments, other structures capable of limiting the separation of the sleeved cover 10 may also be adopted, such as a limiting rib protruding outwards on the side cover plate of the cover on the inner side, a limiting groove recessed on the inner wall of the side cover plate of the cover on the outer side and matching with the limiting rib, and the limiting by matching the limiting rib and the limiting groove.

Further, in the present embodiment, in the plurality of sequentially sleeved covers 10, the inner wall of the innermost cover 10 (i.e. the fourth cover 104) is provided with a fixing portion 1042, and the outermost end of the slide rail is fixedly connected through the fixing portion 1042; the outer end of the outermost lid 10 (i.e., the first lid 101) is provided with a connection plate 1011, and the connection plate 1011 is connected to the processing platform.

Specifically, in this embodiment, the fixing portion 1042 is in a "U" shaped structure, the "U" shaped opening of the fixing portion 1042 corresponds to the inner wall of the innermost cover 10 (i.e., the fourth cover 104) and is fixed on the inner wall of the innermost cover 10 (i.e., the fourth cover 104), the fixing portion 1042 is provided with a fixing hole 1043, and the fixing portion 1043 is fixedly connected to the slide rail, so that the structure is simple and the operation is simple. Of course, in other embodiments, the fixing portion 1042 may have other structures.

Specifically, in this embodiment, the connecting plate 1011 protrudes from the outer surface of the outermost cover 10 (i.e., the first cover 101), so as not to block the opening at the end of the outermost cover 10 (i.e., the first cover 101), which is convenient for the sleeving operation; the connecting plate 1011 is provided with a connecting hole 1012, and is connected with the processing platform through the connecting hole 1012, so that the structure is simple. Of course, in other embodiments, other structures may be used for the connection.

Further, in this embodiment, an opening at an outer end portion of the innermost cover 10 (i.e., the fourth cover 104) is sealed and covered by a sealing cover 1041, so that after the telescopic protection cover is assembled, an outer surface of the telescopic protection cover is sealed, no exposed opening exists, and a blocking effect is better. Of course, after assembly, since the outer end opening of the innermost cover 10 (i.e., the fourth cover 104) is away from the processing platform, in other embodiments, the outer end opening of the innermost cover 10 (i.e., the fourth cover 104) may not need to be covered by the sealing cover 1041.

Further, in this embodiment, the outer surface of the upper cover plate of the cover body 10 is an arc surface with a middle-high height and a low-outer height, so that the fragments or waste liquid with the fragments splashed on the surface of the cover body can flow out through the arc surface in time, thereby facilitating the collection of the waste liquid. Specifically, the upper cover plate with the arc-shaped surface is formed by integrally bending a plane plate, and the inner surface of the upper cover plate is also arc-shaped, so that the upper cover plate is convenient to prepare.

Further, in this embodiment, the cover body 10 is made of steel, the hardness of the steel is good, and the steel is not easy to rust, and the cover bodies 10 that are sleeved with each other form clearance fit through the limitation of the blocking portions (i.e., the first blocking portion 31 and the second blocking portion 32), so as to prevent the cover bodies 10 from directly forming friction, and reduce noise and abrasion.

Specifically, the blocking portions (i.e., the first blocking portion 31 and the second blocking portion 32) are rubber blocking portions, so that noise and wear are less, and the effect is better. Of course, in other embodiments, other materials may be used for the blocking portion.

Furthermore, in this embodiment, the cushion pad 23 is a rubber pad, and the wear of the cushion pad in cooperation with the slide rail is small, and the generated noise is small. Meanwhile, the material of the pulley 22 on the first step surface is also preferably rubber.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
