[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: As Figures 1-5The technical solution shown is a miniature pin component with a scratch-resistant guiding structure. To solve the problem of inconvenient carrying, transportation, and operation of miniature pin components, the following is disclosed: a pin component body 1 and pins 2 evenly spaced inside the pin component body 1; a top protective sleeve 3 is provided at the upper end of the pin component body 1, and a bottom protective box 4 is installed at the lower end of the pin component body 1; the pin component body 1 and the top protective sleeve 3 are connected by a guide locking mechanism, which is provided with a guide block 6, and the inner side of the guide block 6 is fixedly installed on the outer side of the top protective sleeve 3. Furthermore, the inner wall of the pin body 1 is provided with a guide groove 7, and the guide block 6 is slidably connected to the inside of the guide groove 7. The lower end of the top protective sleeve 3 is fixedly installed with an elastic buckle 8, and the bottom of the elastic buckle 8 is embedded in the openings on both sides of the pin body 1. The left and right ends of the pin body 1 are connected with button blocks 9, and the inner side of the button block 9 corresponds to the elastic buckle 8. The middle end of the button block 9 is fixedly installed with a limit plate 10. The upper and lower ends of the elastic buckle 8 are inclined, and the inclined part of the upper end of the elastic buckle 8 is smaller than the inclined part of the lower end.

[0025] During the transport of the miniature pin assembly, the pin 2 is protected by the top protective sleeve 3 and the bottom protective box 4 at the upper and lower ends of the pin assembly body 1. When needed, the top protective sleeve 3 and the bottom protective box 4 can be removed to use the miniature pin assembly, preventing scratches on the miniature pin assembly. Figure 3 and Figure 4 As shown, by pressing the button blocks 9 on the left and right sides of the pin body 1, the button blocks 9 are pressed and squeeze the elastic buckles 8. At this time, the elastic buckles 8 are squeezed and disengage from the pin body 1. Then, by pulling the top anti-slip sleeve, the guide block 6 slides along the guide groove 7 and disengages from the pin 2. This allows the pin 2 to disengage. Conversely, when installing the top anti-slip sleeve, as the elastic buckles 8 are installed, the elastic buckles 8 squeeze the button blocks 9. The button blocks 9 are squeezed and limited by the limiting plate 10. This protects the upper end of the pin 2 and guides the installation of the top protective sleeve 3.

[0026] Example 2: Figures 1-6 The technical solution shown, based on Embodiment 1, discloses the following to address the problem of easy scratching of the miniature pin component: the lower end of the pin component body 1 is connected to the bottom protective box 4 via a pressure sleeve mechanism. A rubber sleeve 5 is installed inside the bottom protective box 4, and the interior of the rubber sleeve 5 corresponds to the lower end of the pin 2. The pressure sleeve mechanism is provided with a fixing block 11, and the outer side of the fixing block 11 is fixedly installed on the inner wall of the bottom protective box 4. A positioning rod 12 is fixedly installed at the middle end of the fixing block 11, and an abutment block 13 is installed through the surface of the positioning rod 12. The upper end of the abutment block 13 is embedded in the snap-fit ​​groove 14 opened at the lower end of the pin component body 1. The outer side of the abutment block 13 is inclined, and an anti-slip pad is fixedly installed on the outer side of the abutment block 13. A pressure spring 15 is provided between the front and rear abutment blocks 13.

[0027] A bottom protective box 4 is installed at the bottom of the pin body 1. When the bottom protective box 4 is installed, the bottom of the pin 2 is aligned with the inner rubber sleeve 5 of the bottom protective box 4, which can protect the bottom of the pin 2. At the same time, with the installation of the bottom protective box 4, the abutment block 13 is embedded in the snap-fit ​​groove 14. Due to the front and back tilting of the abutment block 13, it can slide along the positioning rod 12 inside the fixing block 11 under the setting of the pressure spring 15 as the pin body is installed, and apply pressure to the pin body 1. An anti-slip pad is also provided on the outside of the abutment block 13, which can increase the friction between the abutment block 13 and the pin body 1, further protecting the bottom of the pin 2 and preventing it from being scratched.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
