However, the present application can be practiced according to other embodiments that can not be described in detail herein, and the skilled person can make similar extensions without departing from the scope of the present application, and the present application is not limited to the specific embodiments disclosed below.

[0029] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive of other embodiments.

[0030] Embodiment 1

[0031] Reference Figure 1 and Figure 2 The present application provides a convenient to set aramid sheath, which is the first embodiment of the present application. The convenient to set aramid sheath comprises an aramid sheath body 100, an end opening mechanism 200 and a striding mechanism 300. The end opening mechanism 200 can be used to open and fix one end of the aramid sheath body 100, which facilitates the insertion of the cable into the aramid sheath body 100. The striding mechanism 300 can be used to open the aramid sheath body 100, which facilitates the smooth threading of the cable and prevents jamming.

[0032] Specifically, the end opening mechanism 200 is arranged on the surface of the aramid sheath body 100 and comprises a striding pipe 201, a driving member 202 and a fixing member 203. The aramid sheath body 100 is arranged on the surface of the striding pipe 201, the driving member 202 is mounted on the surface of the striding pipe 201, and the fixing member 203 is arranged on the surface of the driving member 202.

[0033] One end of the striding pipe 201 is chamfered to facilitate the insertion of the striding pipe 201 into one end of the aramid sheath body 100. The driving member 202 drives the fixing member 203 to fix one end of the aramid sheath body 100 arranged on the striding pipe 201, which facilitates the opening and fixing of the aramid sheath body 100 and effectively prevents the loosening of the cable when it passes through the aramid sheath body 100. Meanwhile, the operator can easily operate the moving of the turning plate 202b to arrange the aramid sheath body 100 on the surface of the cable.

[0034] Specifically, the striding mechanism 300 is arranged in the striding pipe 201 and comprises a striding ring 301, a striding member 302, a baffle 303 and a rubber ring 304. The striding ring 301 is movably connected in the striding pipe 201, the striding member 302 is mounted on the surface of the striding ring 301, and the baffle 303 and the rubber ring 304 are fixedly connected to the inner surface of the striding ring 301.

[0035] The aramid sheath body 100 is expanded by moving the support ring 301 inside the aramid sheath body 100, and the cable is conveniently passed through the aramid sheath body 100, which brings great convenience to the operator. The baffle 303 is cross-shaped and limits the cable end inserted into the support ring 301, avoiding the cable end from being in contact with the aramid sheath body 100 and affecting normal passing through the sheath.

[0036] The rubber ring 304 can be replaced and adjusted according to the size of the actual cable. The cable end is inserted into the support ring 301 and tightly connected with the support ring 301 under the action of the rubber ring 304, so as to reduce the risk of the support ring 301 falling off the cable end. When the support ring 301 moves inside the aramid sheath body 100, the support piece 302 can reduce the friction between the support ring 301 and the aramid sheath body 100, and can also strengthen the expansion degree, so that the support ring 301 moves more smoothly.
