[0013] Beneficial effects:

[0014] 1. This spring-loaded bolt fixing mechanism, through the design of the spring and the protruding part, causes the bottom end of the bolt to press against the protruding part outward when inserted into the inner side of the protruding part. This causes elastic deformation of the protruding part and the spring, and the reaction force generated by the elastic deformation makes the inner end of the protruding part tightly adhere to the bottom end surface of the bolt, thus clamping and fixing the bolt, greatly improving the stability of the bolt, making it less likely to fall off, and preventing its displacement. At the same time, the structure of the spring and the protruding part is simple, easy to produce, and has significant effects. Therefore, it reduces processes and costs, increases the product qualification rate, and indirectly optimizes the problem of bolt coating. In addition, the spring is low in cost and suitable for widespread application. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a spring clip fixing bolt mechanism, including a bolt insert 1, a slot 2 that runs from left to right through the top of the outer surface of the bolt insert 1, a spring clip 3 that is movably inserted into the slot 2, a limiting hole 4 that runs from front to back through the bottom of the outer side of the spring clip 3, a protrusion 5 that is provided on the top of the inner walls on both the left and right sides of the spring clip 3, the distance between the inner sides of the protrusions 5 being less than the outer diameter of the bottom end of the bolt 6, a bolt 6 that is movably inserted into the top of the bolt insert 1, the bottom end of the bolt 6 being tightly attached to the protrusion 5, a through hole 7 that runs from front to back through the top of the outer surface of the bolt insert 1, a positioning pin 8 that is movably inserted into the through hole 7, and the positioning pin 8 passing through the interior of the limiting hole 4.

[0021] By using the spring 3 and the protruding part 5, when the bottom end of the bolt 6 is inserted into the inner side of the protruding part 5, it will press the protruding part 5 outward, causing the protruding part 5 and the spring 3 to undergo elastic deformation. The reaction force generated by the elastic deformation will make the inner end of the protruding part 5 tightly adhere to the bottom end surface of the bolt 6, thereby clamping and fixing the bolt 6, greatly improving the stability of the bolt 6, making it less likely to fall off, and preventing its displacement. At the same time, the spring 3 and the protruding part 5 have a simple structure, are relatively easy to produce, and have significant effects. Therefore, it reduces processes and costs, increases the product qualification rate, and indirectly optimizes the problem of the bolt 6 being coated with glue. In addition, the spring 3 has low cost and is suitable for widespread application.

[0022] To facilitate the insertion of the positioning pin 8 into the limiting hole 4 and the through hole 7, this utility model is designed so that the through hole 7 and the limiting hole 4 are at the same horizontal level and communicate with each other. The inner diameters of the through hole 7 and the limiting hole 4 are both adapted to the outer diameter of the positioning pin 8. Because their sizes are compatible and they are at the same horizontal level, it is convenient for the operator to insert the positioning pin 8 into the limiting hole 4 and the through hole 7 smoothly.

[0023] In order to extend the service life of the spring 3 and the protrusion 5, this utility model integrates the spring 3 and the protrusion 5 into one piece. The spring 3 and the protrusion 5 are both made of spring steel. The structure made of spring steel is not easily deformed and has a good rebound effect. Therefore, the service life of the spring 3 and the protrusion 5 can be extended.

[0024] In order to ensure that the positioning pin 8 is not easily damaged during use, the positioning pin 8 is made of stainless steel. Stainless steel has high hardness, is not easily deformed, and is not easily rusted or broken, thus ensuring that the positioning pin 8 is not easily damaged during use.

[0025] In order to facilitate the worker to smoothly insert the spring piece 3 into the slot 2, the inner diameter of the slot 2 is designed to match the outer diameter of the spring piece 3. Therefore, the two sets of structural dimensions are matched, which makes it easier for the worker to smoothly insert the spring piece 3 into the slot 2.

[0026] In use, the operator first inserts the spring piece 3 into the slot 2, so that the limiting hole 4 and the through hole 7 are on the same horizontal plane in the front-back direction, making the limiting hole 4 and the through hole 7 communicate. Then, the operator inserts the positioning pin 8 into the through hole 7, which also passes through the limiting hole 4, thus fixing the spring piece 3 and the bolt insert 1. Then, the operator inserts the bolt 6 downward into the top of the bolt insert 1, so that the bottom end of the bolt 6 contacts the protruding part 5. Because the spacing between the inner sides of the protruding part 5 of the spring piece 3 is smaller than the outer diameter of the bottom end of the bolt 6 during production, as the bottom end of the bolt 6 goes deeper, it will squeeze the protruding part 5 outward, causing the protruding part 5 and the spring piece 3 to undergo elastic deformation. Therefore, the spring piece 3 will generate a reaction force, so that the inner side of the protruding part 5 is tightly pressed against the outer surface of the bottom end of the bolt 6 until the bolt 6 is fully inserted. Thus, the bolt is clamped and fastened.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0028] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation.

[0029] 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.
