As such products gradually become popular in the market, more and more people know their structural characteristics for self-defense purposes. This leads to the fact that in daily social occasions, once a user carries such a self-defense pen, his or her self-defense intention is easily detected by others. For example, in normal social activities such as business negotiations, friends gatherings, or campus exchanges, if others recognize that the user is carrying a self-defense pen, it is equivalent to the user's privacy being leaked. This situation will bring many negative effects to the user, and it is easy for others to misunderstand that the user is too defensive, and may even be unilaterally regarded as a timid person, or an individual who lacks a sense of security and has low self-esteem, which will seriously interfere with the user's normal social relationships, cause unnecessary psychological burdens to the user, and affect his or her image and communication experience in social occasions; Although self-defense knives have strong self-defense functions, their blades are usually designed to be sharp. According to the relevant identification standards for controlled knives, most of these products are classified as controlled knives. This makes it difficult for self-defense knives to be legally and conveniently purchased and carried by the public, and thus cannot effectively meet people's daily needs for a portable and multifunctional tool that can take into account both self-defense and other practical functions. Overall, the market currently lacks a product that can cleverly disguise its self-defense function to avoid unnecessary misunderstandings in normal social interactions, can be circulated legally and in compliance with regulations on the market, and has multiple practical functions that combine personal protection with daily use.

There is a pen clip on the side of the pen cap 5, which can fix the pen body, facilitate carrying, and can also be clipped to a page of a book, etc., for easy access.

[0030] The working principle of the multifunctional self-defense pen provided by the present invention is as follows: When the user needs to use the writing function, he only needs to screw the selected pen tip 1 (such as a steel pen tip) onto the interface at one end of the pen body 1 through the external thread 21, and the external thread 21 and the internal thread 12 are threadedly connected, and then writing can be performed like an ordinary pen. During the writing process, ink can flow out of the pen tip evenly and smoothly, and the writing experience is no different from that of an ordinary writing tool. When encountering an emergency and needing self-defense, the user quickly pulls out the knife 3 from the protective shell 4. Since the pen body 1 is connected to the knife 3, the pen body 1 is the handle of the knife 3. The user holds the pen body 1 and uses the sharp part of the knife 3 for self-defense. Since the knife 3 is made of stainless steel and has a certain hardness, it can play a deterrent and defensive role to a certain extent. However, it should be noted that when using the self-defense function, laws and regulations should be strictly observed to ensure the safety of oneself and others. When it is necessary to cut items, such as cutting fruits, the knife 3 is taken out from the protective shell 4, the pen body 1 is held, and the blade of the knife 3 is used to cut the fruit. Since the blade is sharp and reasonably designed, the fruit can be easily cut into the required shape and size. When unpacking express delivery, the knife 3 is also pulled out, and the blade is used to gently scratch along the tape of the express package to quickly open the package, which is convenient and quick. When encountering a situation where screws need to be tightened, such as furniture assembly or small appliance repair, the tool 3 is taken out of the protective shell 4, and the flat-head screwdriver head 31 at the end of the tool 3 is aimed at the screw head and rotated clockwise or counterclockwise to tighten or loosen the screw. The size and hardness of the flat-head screwdriver head 31 can meet the operating requirements of most common screws, providing convenience for users.
