[0002] In current industrial production and daily life, as an important connecting and fixing component, the pin shaft is widely used in many fields such as mechanical equipment, automobile parts, and furniture assembly. However, with the continuous development of technology and the increasingly complex application environment, some problems have gradually emerged in the traditional pin shaft connection method.

[0003] First of all, when the traditional pin shaft connection method is subjected to external forces such as vibration and impact, it often loosens or even falls off. This situation is particularly prominent in high-precision and high-requirement fields such as mechanical equipment and automobile parts. According to statistics, the equipment failures and safety accidents caused by the loosening or falling off of the pin shaft each year account for a considerable proportion, bringing huge economic losses and safety risks to enterprises and individuals.

[0004] Secondly, the traditional pin shaft connection method usually requires additional fasteners or tools during the installation and disassembly process, which not only increases the complexity of installation and disassembly, but also may cause damage or deformation of the connecting parts. Especially in some application occasions where the connecting parts need to be frequently replaced or adjusted, this complexity and damage risk are more prominent. Content of the Utility Model

A reserved hole 2 is opened on the surface of the pin body 1. A reserved groove 4 is opened at one end of the pin body 1 close to the reserved hole 2. A clamping plate 5 is slidably connected inside the reserved groove 4. An insertion bar 6 is fixed on the surface of the clamping plate 5. The insertion bar 6 is inserted on the surface of the limiting bar 3, and the limiting bar 3 is inserted into the reserved hole 2; by setting the reserved hole and the limiting bar, the pin can be effectively fixed after being inserted, and through the cooperation of the clamping plate and the insertion bar, the limiting bar can be conveniently fixed in the reserved hole without using additional fasteners or tools, simplifying the installation process and preventing loosening or falling off caused by vibration or impact, etc., greatly improving the stability of the connection.

[0024] Embodiment 2

[0025] Referring to the attached Figures 4 to 7 shown, on the basis of Embodiment 1, in order to realize the anti-detachment limit of the limiting bar 3 after being inserted into the reserved hole 2, the reserved groove 4 is a "C"-shaped groove, the clamping plate 5 is a "C"-shaped plate-like structure, there are two insertion bars 6, and the two insertion bars 6 are respectively fixed on the two parallel side plates of the clamping plate 5. Two anti-detachment insertion holes 7 are opened on the surface of the limiting bar 3. After the limiting bar 3 is inserted into the reserved hole 2, the two insertion bars 6 are respectively inserted into the two anti-detachment insertion holes 7; the width of the clamping plate 5 is less than the width of the reserved groove 4. A plurality of anti-deviation blocking bars 11 are fixed on the surface of the reserved groove 4. The anti-deviation blocking bars 11 are arranged in a square pattern, and the reserved groove 4 is located between the plurality of anti-deviation blocking bars 11; a notch 8 is opened on the surface of the clamping plate 5, and an elastic band 9 is fixed at the center of the notch 8.
