[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 2 The utility model provides an embodiment: based on the spring positioning pin seat, it includes a base shell 1. First, the base shell 1 is placed in a suitable position. A guide groove 12 is opened inside the base shell 1. Then, the pin is placed in the inner wall of the guide groove 12. At this time, the pin will enter the inside of the base shell 1 along the guide groove 12. Cavities 2 are opened on the left and right sides of the bottom of the base shell 1. The end of the clamping column 5 away from the limit plate 4 is fixedly connected with a rubber ball 6. As the pin moves, the bottom contacts the rubber ball 6. At this time, the rubber ball 6 is squeezed to make the clamping column 5 slide into the inside of the cavity 2. A spring 3 is arranged inside the cavity 2. At this time, the spring 3 is compressed and absorbs external force during compression due to its own elastic properties.

[0023] The interior of the cavity 2 is slidably connected to a limit plate 4 and generates a reaction force on the limit plate 4. A clamping column 5 is fixedly connected to one side of the limit plate 4. One end of the spring 3 is fixedly connected to the inner side of the cavity 2, and the other end of the spring 3 is fixedly connected to the side of the limit plate 4 away from the clamping column 5. The limit plate 4 can limit the spring 3 to prevent severe deformation during use. The outside of the clamping column 5 is slidably connected to the inner wall of the cavity 2, so that the rubber ball 6 fits more closely with the pin, thereby fixing the pin.

[0024] Reference Figure 3 A rubber ring 7 is fixedly connected to the inside of the base shell 1, and a fixing component is arranged inside the base shell 1, which includes a clamping ring 8, a clamping plate 9 and an auxiliary positioning ring 10. The correction ring 11 can correct the position of the pin and then enter the inside of the clamping plate 9. The inside of the clamping plate 9 is slidably connected with the auxiliary positioning ring 10. At this time, the pin enters the inside of the clamping plate 9 and squeezes the auxiliary positioning ring 10 outward. The bottom of the clamping plate 9 contacts the outer inner wall of the clamping ring 8, and the outside of the auxiliary positioning ring 10 contacts the inner wall of the clamping plate 9. The auxiliary positioning ring 10 slides downward along the inside of the clamping plate 9.

[0025] A correction ring 11 is fixedly connected to the top of the clamping plate 9, and the outside of the correction ring 11 is fixedly connected to the inner wall of the base shell 1. At this time, the outside of the pin will fit the auxiliary positioning ring 10 and the correction ring 11, the outside of the clamping plate 9 is in contact with the inner wall of the clamping ring 8, and the outside of the clamping ring 8 is slidably connected to the inside of the base shell 1. The inner wall of the base shell 1 is fixedly connected with the clamping plate 9, and the bottom of the auxiliary positioning ring 10 is in contact with the bottom of the clamping plate 9. At this time, the correction ring 11 will squeeze the clamping ring 8 and the rubber ring 7. Due to the elasticity of the rubber ring 7 itself, the clamping ring 8 and the clamping plate 9 can fit more closely, which can preliminarily fix the pin and can adapt to the outside of different pins for fixing, which is convenient for disassembly and installation.

[0026] Working principle: First, place the base shell 1 in a suitable position, then put the pin into the inner wall of the guide groove 12, at this time, the pin will enter the inside of the base shell 1 along the guide groove 12, and the correction ring 11 can correct the position of the pin and then enter the inside of the card plate 9. At this time, the pin enters the inside of the card plate 9 and squeezes the auxiliary positioning ring 10 outward. The auxiliary positioning ring 10 slides down along the inside of the card plate 9. At this time, the outside of the pin will fit the auxiliary positioning ring 10 and the correction ring 11. At this time, the correction ring 11 will squeeze the clamping ring 8 and the rubber ring 7. The elasticity of the rubber ring 7 itself will make the clamping ring 8 and the clamping plate 9 fit more closely, and the pin can be initially fixed. As the pin moves, the bottom contacts the rubber ball 6. At this time, the rubber ball 6 is squeezed to make the clamping column 5 slide into the cavity 2. At this time, the spring 3 is compressed and absorbs external force due to its own elastic properties during compression, and generates a reaction force on the limit plate 4. The limit plate 4 can limit the spring 3 to prevent severe deformation during use, so that the rubber ball 6 and the pin fit more closely, thereby fixing the pin.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
