[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4The utility model provides a technical solution: a spring-type nut fixing mechanism, comprising a nut inserting pin 1, a spring piece 2 is inserted through the top of the outer surface of the nut inserting pin 1, a positioning pin 3 is inserted through the top of the outer surface of the nut inserting pin 1, the positioning pin 3 also passes through the outer side surface of the spring piece 2, and a nut 4 is sleeved on the top of the outer surface of the nut inserting pin 1.

[0024] Through the setting of the spring piece 2, when the nut 4 is sleeved on the top of the nut pin 1, the protruding parts on the left and right sides of the spring piece 2 will be squeezed by the inner wall of the nut 4, which will cause the spring piece 2 to generate a reaction force, so that the protruding parts on the left and right sides of the spring piece 2 will tightly rest on the inner wall of the nut 4, thereby realizing the function of reinforcing the nut 4, greatly improving the stability of the nut 4, and making it less likely for the nut 4 to shift or even fall off. At the same time, due to the setting of the spring piece 2, the problem of rubber encapsulation of the nut 4 is optimized.

[0025] The function of reinforcing the nut 4 can be achieved through fewer structures, which indirectly reduces the process and cost. At the same time, the spring piece 2 has low cost and is suitable for promotion. At the same time, because the structure of the spring piece 2 is relatively simple, it is also convenient to put the nut 4 in.

[0026] In order to facilitate the staff to insert the spring piece 2 into the interior of the nut setting pin 1, the utility model provides a left-right through slot on the top of the outer surface of the nut setting pin 1. The inner diameter of the slot is adapted to the outer diameter of the spring piece 2. Because the sizes of the two groups of structures are adapted, the staff can smoothly insert the spring piece 2 into the interior of the slot, which makes it convenient for the staff to insert the spring piece 2 into the interior of the nut setting pin 1.

[0027] In order to facilitate the staff to control the insertion of the locating pin 3 into the interior of the nut setting needle 1 and the spring piece 2, the utility model provides a first through hole that passes through the front and back on the top of the outer surface of the nut setting needle 1, and a second through hole that passes through the front and back on the outer side of the spring piece 2. The first through hole and the second through hole are at the same horizontal position, and the inner diameters of the first through hole and the second through hole are both adapted to the outer diameter of the locating pin 3. Therefore, it is convenient for the staff to control the insertion of the locating pin 3 into the interior of the nut setting needle 1 and the spring piece 2.

[0028] In order to fix the spring piece 2 and prevent it from moving, the utility model sets the number of positioning pins 3 to one group, and inserts the positioning pins 3 into the inside of the nut needle 1 and the spring piece 2 to limit and fix the inside of the nut needle 1 and the spring piece 2, thereby fixing the spring piece 2 and preventing it from moving.

[0029] In order to prevent the positioning pin 3 from falling off on its own, the utility model provides an anti-skid layer on the outer surface of the positioning pin 3. The material of the anti-skid layer is set to rubber. The anti-skid layer made of rubber has a good anti-skid effect and can increase the friction between it and the inner wall of the nut insert pin 1 and the spring piece 2. Therefore, the positioning pin 3 will not fall off on its own without the influence of external force, thereby preventing the positioning pin 3 from falling off on its own.

[0030] In order to extend the service life of the shrapnel, the present invention sets the shrapnel 2 to be made of spring steel. The shrapnel 2 made of spring steel has good rebound effect, is not easy to deform, and is not easy to be damaged, thereby extending the service life of the shrapnel.

[0031] When in use, first insert the spring piece 2 into the inside of the nut pin 1 so that the first through hole and the second through hole respectively opened on the spring piece 2 and the nut pin 1 are at the same horizontal position, then insert the positioning pin 3 into the inside of the nut pin 1 and the spring piece 2, limit and fix the nut pin 1 and the spring piece 2, and then put the nut 4 on the top of the nut pin 1. The protruding parts on the left and right sides of the spring piece 2 protrude from the left and right sides of the outer surface of the nut pin 1. Therefore, in the process of putting the nut 4 on the nut pin 1, the inner wall of the nut 4 will squeeze the protruding parts on the left and right sides of the spring piece 2 inward. When the spring piece 2 undergoes elastic deformation, a reaction force will be generated. Therefore, the reaction force will be applied to the inner wall of the nut 4 through the protruding parts on the left and right sides of the spring piece 2, so that the protruding parts on the left and right sides of the spring piece 2 will firmly rest on the inner wall of the nut 4. At this point, the fixation of the nut 4 is completed and the stability is improved.

[0032] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.

[0033] The sizes and shapes of all components in this structure are not specifically limited here and need to be produced according to actual conditions.

[0034] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
