[0009] An upper locking ring and a lower locking ring are connected to the external thread of the thick outer sheath; a first locking ring reserved groove and a second locking ring reserved groove are respectively provided on the upper locking ring and the lower locking ring.

[0010] Furthermore, two side walls of the first sheath slot of the thick outer sheath are symmetrically provided with dovetail grooves; and notches are provided on the elastic layer and the inner lining layer to facilitate the entry of the pull wire.

[0011] The plug-in strip is sealingly inserted in the dovetail groove, wherein the plug-in strip is a "cross" structure, which fills the first sheath slot and the gap for the pull wire to enter respectively.

[0012] Furthermore, the elastic layer is made of one of elastic yarn, rubber-coated yarn and elastic rope.

[0013] Furthermore, the inner lining layer is made of a wear-resistant insulating material, and the material of the inner lining layer (13) is a nylon insulating sheet or a PET insulating sheet.

[0014] Furthermore, external threads are respectively provided at both ends of the thick outer sleeve, and the upper locking ring and the lower locking ring are respectively threadedly connected to the two ends of the thick outer sleeve; and a first locking threaded hole and a second locking threaded hole are respectively radially opened on the upper locking ring and the lower locking ring; and the upper locking ring and the lower locking ring are respectively locked and positioned on the thick outer sleeve by bolts.

[0015] Furthermore, the thick outer sheath is connected to the thin outer sheath through a tapered tube.

[0016] Compared with the prior art, the beneficial technical effects of the utility model are:

[0017] In the utility model, a plug-in strip is inserted into the first sheath slot of the outer sheath, thereby blocking the outlet of the pull wire, and a dovetail-shaped limiting groove is used to prevent the pull wire from falling off and being stuck in the sheath slot;
