Multifunctional marlin spike

A marlin spike, comprising a threading-cone functional head (1), a connecting tube (2), and a threading head (3);

• wherein the threading head (3) is disposed at an upper end of the connecting tube (2), and the threading-cone functional head (1) is disposed at a lower end of the connecting tube (2);
• the connecting tube (2) is a hollow tube structure, a tapered knitting needle (5) is configured to be inserted in a connecting tube cavity (4) of the connecting tube (2), and the tapered knitting needle (5) comprises a threaded head (6), a threading needle body (7) connected to the threaded head (6), and a tapered needle (8) connected to the threading needle body (7);
• wherein the tapered knitting needle (5) is configured to be inserted into the connecting tube (2) from the tapered needle (8) to the threaded head (6), screw threads provided on a bottom part of the threaded head (6) are threaded with screw threads provided on an inner wall of the connecting tube (2), a top part of the connecting tube (2) is provided with a top threaded tube (9), and the threading head (3) is threaded with the top threaded tube (9) and connected to the connecting tube (2);
• and
• wherein a top part of the threading-cone functional head (1) is provided with a threaded neck tube (10), the threaded neck tube (10) is connected to the threaded head (6) of the tapered knitting needle (5), and thus the threading-cone functional head (1) is indirectly connected to the connecting tube (2);
• or the threaded neck tube (10) is threaded with the top part of the connecting tube (2), thereby to achieve a connection of the threading-cone functional head (1), the connecting tube (2) and the tapered knitting needle (5).
