Description

technical field [0001] The invention is a self-protection lifesaving pen, which belongs to the technical field of daily tools. Background technique [0002] In daily life, people often need to carry life-saving tools. The life-saving pen combines multiple functions of life-saving tools and writing pens, and has become one of people's choices. For example, in the comparison technology: [0003] Comparative technology 1: a "multifunctional lifesaving pen" disclosed by the authorized announcement number CN 201659791U, which provides a multifunctional lifesaving pen. Its "triangular knife" provides protection, the "pen cap" provides protection for the "upgrade module" inside the pen cap, and the "pen holder" provides protection for its internal "knife" and "storage box"; the structure of this is more complicated , It is not convenient enough to use the various tools. The "three-edged knife set" has no other function except to protect the "three-edged knife", and it is not possi...

Problems solved by technology

[0003] Comparative technology 1: a "multifunctional lifesaving pen" disclosed by the authorized announcement number CN 201659791U, which provides a multifunctional lifesaving pen. Its "triangular knife" provides protection, the "pen cap" provides protection for the "upgrade module" inside the pen cap, and the "pen holder" provides protection for its internal "knife" and "storage box"; the structure of this is more complicated , It is not convenient enough to use the various tools. The "three-edged knife set" has no other function except to protect the "three-edged knife", and it is not possible to use the "three-edged knife set" with the life-saving tool when using the "three-edged knife". The pen is combined into one, that is, when using the "triangular knife", the "triangular knife cover" is separated from the lifesaving pen and is easy to lose; therefore, this technology has complex structure and inconvenient use;

[0004] Comparative technology 2: a "titanium alloy multifunctional tactical pen" disclosed in the authorized announcement number CN 204055045 U (45), wherein "the nib (4) is threadedly connected to the pen cap (5)", or " The nib 4 is screwed into the internal thread of the groove 7, and then the pen cap 5 is screwed on the nib 4 to complete the T-shaped deformation, that is, the position of the pen cap is on the nib in several combinations; Therefore, during carrying, no protective measures are taken for the "pen cap 5 or the hard titanium alloy cone at the top of the pen key 1", which is easy to cause damage to oneself, others or other items during carrying, and is not easy to carry;

[0005] In the above-mentioned and existing life-saving pen products and technical solutions, the life-saving pen is composed of a pen holder with a pen core and a pen cap, and a detachable The pen holder is composed of a nib at one end and a tool head at the other end; when carrying, the pen cap can only protect the nib but not the tool head, or you can only choose one between the nib and the tool head for protection, or As disclosed in Comparative Technology 1, the special-purpose "triangular knife sheath" is used to protect its "triangular knife"; like this, the implementation technology is complicated, inconvenient to use, or the tool head or pen point is exposed when carried , it is easy to cause harm to yourself or others or other items during carrying, and it is not easy to carry
