[0028] The following will further elaborate on the present utility model in detail with reference to the Figures 1 to 4 drawings, but this is not a limitation to the present utility model.

[0029] Such as Figure 1 and 4As shown, in an embodiment of the present utility model, the nut fastening device includes an outer support body 1, an inner support body 2, and an adsorption component 4. An assembly cavity 13 is provided inside the outer support body 1. The inner support body 2 is arranged inside the assembly cavity 13 along the depth direction of the assembly cavity 13. The adsorption component 4 is arranged in the assembly cavity 13 between the outer support body 1 and the inner support body 2. And a fastening groove 11 is provided between the adsorption component 4, one side end of the inner support body 2, and the inside of one side of the outer support body 1.

[0030] Through the fastening limiting effect of the fastening groove on the nut and the supporting limiting effect of the inner support body on the nut in the technical solution of the present utility model, combined with the adsorption limiting effect of the adsorption component on the nut assembled in the fastening groove, three different limiting stresses on the nut can be realized, thereby improving the assembly stability of the nut, preventing it from falling off the fastening device, and thus enhancing the safety of use and extending its service life.

[0031] Specifically, in some embodiments, the adsorption component 4 is a magnet. Among them, the magnet is an electromagnet or a common magnet. Since the material of the nut is generally a metal material, this structure further improves the assembly stability of the nut through the adsorption limiting effect of the electromagnet or the common magnet on the nut on the inner wall of the turntable to the fastening groove 11, preventing it from falling off the fastening device.

[0032] Specifically, in some embodiments, as Figure 2 and 3 shown, the adsorption component 4 is connected to the inner wall of the outer support body 1. And one side end of the adsorption component 4 facing the fastening groove 11 is flush with one side end of the inner support body 2 facing the fastening groove 11. And the inner wall of the fastening groove 11 is used for tightly connecting with the outer side wall of the nut. This structure avoids the shaking of the nut during assembly through the flush setting of the adsorption component 4 and the inner support body 2. And then through the tight connection between the fastening groove 11 and the fastening groove 11, the flatness of the nut assembled inside the fastening groove 11 can be guaranteed, which is beneficial to improving the assembly stability.

[0033] Among them, in some other embodiments, one side end of the adsorption component 4 facing the fastening groove 11 extends into the fastening groove 11. And the inner wall of the fastening groove 11 is used for tightly connecting with the outer side wall of the nut. This structure can effectively improve the limiting stability between the nut and the adsorption component 4 through the adsorption component 4 with a larger contact surface.

[0034] Specifically, in some embodiments, as Figure 1 and 3As shown, an inner cavity 21 communicating with the fastening groove 11 is provided inside the inner support 2. Through the limiting support of one end of the inner support 2 on the nut and the limiting assembly effect of the inner cavity 21 on structures such as the connecting rod on the nut, the assembly convenience and stability of the nut can be improved. Among them, as Figure 3 shown, the inner support 2 is a limiting columnar tube 23 made of (metal material, such as steel material); preferably a cylindrical tube or a square columnar tube. Through the columnar inner support 2, the stability of the support can be effectively guaranteed. Further, as Figure 3 shown, a partition block 22 is provided inside the inner support 2; the projection of the partition block 22 towards the opening in the inner cavity 21 covers the opening in the inner cavity 21; that is to say, the internal partition block 22 can divide the inner cavity 21 into two non-communicating upper and lower spaces, avoiding the influence of liquid leakage and other phenomena at the bottom of the outer support 1 and the inner support 2 on the nuts in the upper half, thereby improving the stability of use and extending its service life.

[0035] Specifically, in some embodiments, as Figure 1 and 2 shown, the nut fastening device further includes a filling body 3; the filling body 3 is arranged between the outer support 1 and the inner support 2, and / or, the filling body 3 is arranged between the outer support 1 and the adsorption component 4. Preferably, the filling body 3 is arranged between the outer support 1 and the inner support 2 and between the outer support 1 and the adsorption component 4. Further, the filling body 3 is selected from polyurethane glue, silicone glue or epoxy resin glue. That is to say, by filling polyurethane glue, silicone glue or epoxy resin glue in the magnet and steel pipe areas, the phenomenon of shaking of the inner support 2 and the phenomena of slipping and loosening of the adsorption component 4 can be avoided; thereby improving the stability of the structure.

[0036] Specifically, in some embodiments, as Figure 1 and 2 shown, an installation groove 31 communicating with the fastening groove 11 is provided on the filling body 3; the adsorption component 4 is limit-connected to the installation groove 31. This structure can ensure the installation stability of the adsorption component 4 and reduce the occurrence of phenomena such as slipping and loosening. Among them, as Figure 2 shown, the relationship between the height L1 of the installation groove 31 and the height L2 of the adsorption component 4 satisfies: L2≥L1. This structure can ensure the assembly stability and also guarantee the realization of the adsorption positioning function.

[0037] Specifically, in some embodiments, as Figure 1 and 4As shown, an assembly channel 12 is further provided inside the outer support 1; one end of the assembly channel 12 communicates with the assembly cavity 13; and the other end of the assembly channel 12 penetrates through the outer support 1. Among them, as Figure 4 shown, the outer support 1 includes a support section 101, a connection section 102, and an end section 103 arranged in sequence from top to bottom; the fastening groove 11 is provided inside the support section 101 on the side away from the connection section 102; the other end of the assembly channel 12 penetrates through the support section 101, the connection section 102, and the end section 103 respectively; and the width of the support section 101 is greater than the width of the connection section 102; the width of the support section 101 is greater than or equal to the width of the end section 103; the width of the end section 103 is greater than the width of the connection section 102.
