The existing stripping knife has certain limitations in use, and the existing stripping knife is prone to separation from the cable during the stripping process, which requires stripping again, which is troublesome. Therefore, it needs to be improved. Summary of the invention

[0004] The purpose of the present invention is to provide a special stripping knife for the outer semi-conductive layer of a cable, which solves the problem that the existing stripping knife has certain limitations in use and the existing stripping knife is prone to separation from the cable during the stripping process, requiring stripping again, which is quite troublesome.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a special stripping knife for the outer semi-conductive layer of a cable, comprising a knob and two sleeves, wherein two symmetrically distributed threaded rods are fixedly connected to the knob, and a threaded sleeve is threadedly connected to the outside of each threaded rod, one of the threaded sleeves is hinged to one of the sleeves, and a buckle is fixedly connected to the other threaded sleeve, and the buckle is clipped to the other sleeve, wherein an adjustment mechanism is arranged in one of the sleeves, and a blade is arranged on the adjustment mechanism.

[0006] Preferably, each jacket is provided with a ball bearing, the number of the ball bearings is two, and the two ball bearings are symmetrically distributed on the jacket. The design of the ball bearings can reduce the friction between the jacket and the cable.

[0007] Preferably, a handle is fixedly connected to the jacket, and the handle is made of stainless steel. The design of the handle facilitates the whole to slide outside the cable.

[0008] Preferably, the adjustment mechanism includes a mounting cover, a threaded shaft, a knob, a connecting sleeve, a limiting bolt, a ring groove and a guide sleeve, wherein a mounting cover is mounted on one of the jackets by screws, a threaded shaft is threadedly connected inside the mounting cover, one end of the threaded shaft is rotatably connected to a connecting sleeve, a limiting bolt is threadedly connected inside the connecting sleeve, the tail end of the limiting bolt is slidably connected to the threaded shaft, a guide sleeve is fixedly connected to the outside of the connecting sleeve, the guide sleeve is slidably connected to the jacket, and the guide sleeve is fixedly connected to the blade. The design of the adjustment mechanism facilitates the adjustment of the position of the blade.

[0009] Preferably, the threaded shaft is provided with an annular groove, and the annular groove is slidably connected with the limiting bolt. The design of the annular groove cooperates with the limiting bolt to facilitate the connection between the threaded shaft and the connecting sleeve.

[0010] Preferably, the other end of the threaded shaft is fixedly connected with a knob, and the knob is made of stainless steel. The design of the knob facilitates the rotation of the threaded shaft.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present invention provides two jackets, an adjustment mechanism is provided in one of the jackets, and a blade is provided on the adjustment mechanism. Thus, the position of the blade can be adjusted by the adjustment mechanism, thereby meeting the needs of stripping the outer semi-conductive layer of the cable with different thicknesses, thereby increasing applicability.

[0013] 2. The present invention arranges components such as a knob, a threaded rod, and a threaded sleeve between two jackets, and two threaded rods are rotatably arranged. A threaded sleeve is arranged on the outside of each threaded rod, one of the threaded sleeves is hinged to one of the jackets, and a buckle is arranged on the other threaded sleeve, and the buckle is snap-connected to the other jacket. In this way, the displacement generated by the threaded movement of the threaded rod and the threaded sleeve can make the jacket wrap the cable, thereby ensuring that the blade is always in contact with the cable and can strip the outer semi-conductive layer of the cable at one time.

Two symmetrically distributed threaded rods 3 are fixedly connected to the knob 2. A threaded sleeve 4 is threadedly connected to the outside of each threaded rod 3. One threaded sleeve 4 is hinged to one of the jackets 1. A buckle 5 is fixedly connected to the other threaded sleeve 4. The buckle 5 is snapped with the other jacket 1. Each jacket 1 is provided with a ball 6. The number of the ball 6 is two. The two ball 6 are symmetrically distributed on the jacket 1. The design of the ball 6 reduces the friction between the jacket 1 and the cable. An adjusting mechanism 7 is provided in one of the jackets 1. A blade 8 is provided on the adjusting mechanism 7. A handle 9 is fixedly connected to the jacket 1. The handle 9 is made of stainless steel. The design of the handle 9 facilitates the sliding of the whole on the outside of the cable.

[0021] See also Figure 2 , Figure 3 , Figure 4 The adjusting mechanism 7 includes a mounting cover 71, a threaded shaft 72, a knob 73, a connecting sleeve 74, a limiting bolt 75, an annular groove 76 and a guide sleeve 77. A mounting cover 71 is mounted on one of the jackets 1 by screws. A threaded shaft 72 is connected to the mounting cover 71 by threads. One end of the threaded shaft 72 is rotatably connected to the connecting sleeve 74. The connecting sleeve 74 is connected to the limiting bolt 75 by threads. The tail end of the limiting bolt 75 is slidably connected to the threaded shaft 72. An annular groove 76 is provided on the threaded shaft 72. The annular groove 76 is slidably connected to the limiting bolt 75. The design of the annular groove 76 cooperates with the limiting bolt 75 to facilitate the connection between the threaded shaft 72 and the connecting sleeve 74. The other end of the threaded shaft 72 is fixedly connected to the knob 73, which is made of stainless steel. The design of the knob 73 facilitates the rotation of the threaded shaft 72. The outside of the connecting sleeve 74 is fixedly connected to the guide sleeve 77. The guide sleeve 77 is slidably connected to the jacket 1, and the guide sleeve 77 is fixedly connected to the blade 8. The design of the adjusting mechanism 7 facilitates the adjustment of the position of the blade 8 .

[0022] The specific implementation process of the present invention is as follows: when in use, two jackets 1 are sleeved on the outside of the stripped cable, and then one of the threaded sleeves 4 is rotated so that the buckle 5 on the other threaded sleeve 4 is inserted into the other jacket 1, and then the knob 2 is rotated, and the knob 2 drives the two threaded rods 3 to rotate, and the threaded sleeves 4 move toward each other through the threaded movement between the threaded rods 3. At this time, the threaded sleeves 4 and the buckle 5 make the two jackets 1 close to each other and clamp and wrap the cable, and the ball 6 on the inner side of the jacket 1 contacts the cable, and then the knob 73 is rotated, and the knob 73 drives the threaded shaft 72 to rotate , and the threaded shaft 72 is displaced by the threaded movement between the threaded shaft 72 and the mounting cover 71. At this time, the threaded shaft 72 drives the guide sleeve 77 to move through the connecting sleeve 74, and the guide sleeve 77 drives the blade 8 to move and enter the outer semi-conductive layer of the cable. Then, the two handles 9 are pulled downward to make the jacket 1 move downward, and the blade 8 strips the outer semi-conductive layer of the cable. Moreover, due to the jacket 1, the blade 8 is always located in the cable, and the stripping is completed at one time. Moreover, by controlling the moving distance of the blade 8, the outer semi-conductive layers of the cable with different thicknesses can be stripped, thereby increasing applicability.
