[0029] Refer to the attached Figure 1-7 , the manual wire stripping tool includes a fixed block 1. The left end of the fixed block 1 is provided with an installation groove 2 opening to the side. The bottom of the installation groove 2 is provided with a through hole 3. A base 4 is arranged in the installation groove 2. A wire stripping needle 5 is connected to the base 4. The other end of the wire stripping needle 5 extends outwards through the through hole 3. The installation groove 2 is connected with a handle 6 through a connecting component. One end of the handle 6 is in contact with the end face of the base 4. The connecting component has a detachable structure with a locking function. When in use, by using the connecting component to control the distance between the fixed block 1 and the handle 6, the fixation and limitation of the base 4 are realized, so as to realize the fixation of the wire stripping needle; at the same time, the inconvenience caused by directly holding the wire stripping needle by hand and affecting the product quality is avoided.

[0030] The connecting component includes an internal thread 7, the internal thread 7 is arranged on the groove wall of the installation groove 2, an external thread 8 is provided on the outer wall of the right end of the handle 6, and the external thread 8 is matched with the internal thread 7. During use, through the threaded connection mode between the handle 6 and the fixed block 1, the fixation and limitation of the base are realized, and then the fixation and limitation of the wire stripping needle 5 are realized; and it is convenient for disassembly, installation and maintenance.

[0031] The connecting component includes a plurality of rotating grooves 9, the rotating grooves 9 are arranged on the outer wall of the fixed block 1, and the rotating grooves 9 are arranged in the left-right direction. A rotating shaft 10 is arranged at the left end of the rotating groove 9, the rotating shaft 10 is arranged in the front-back direction, and both ends of the rotating shaft 10 are fixed on the fixed block 1. A pressing rod 11 is rotatably connected to the rotating shaft 10. A limiting groove 12 communicating with the installation groove 2 is arranged at the left end of the rotating groove 9. A limiting block 13 is arranged on the groove wall of the end of the limiting groove 12 close to the installation groove 2. A ejector rod 14 is slidably connected to the limiting groove 12.
