DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Reference Figure 1-Figure 5 , a fastener for installation on the support frame includes a threaded rod 1, one end of the threaded rod 1 is fixedly connected to the first connecting column 2, one end of the threaded rod 1 is sleeved with a knob cover 3, a spring 4 is arranged in the knob cover 3, one end of the spring 4 is fixedly connected to an arc-shaped block 5, one side of the arc-shaped block 5 is against the first connecting column 2, and the side of the first connecting column 2 is fixedly connected to a first limiting plate 6, the inner wall of the knob cover 3 is fixedly connected to a rectangular block 7, and a limiting groove is provided on one side of the rectangular block 7, an annular cavity 8 is provided in the knob cover 3, one end of the spring 4 is fixedly connected to the annular cavity 8, the arc-shaped block 5 is slidably connected to the annular cavity 8, one end of the first connecting column 2 is fixedly connected to a limiting ring 9, and a rectangular opening is provided on the limiting ring 9.

[0023] The threaded rod 1 and the knob cover 3 are produced separately and assembled together when in use. The knob cover 3 is made of plastic. The two springs 4 and the two arc-shaped blocks 5 in the knob cover 3 are symmetrically distributed. The two first limit plates 6 and the rectangular block 7 are also symmetrically distributed.

[0024] Align the first limiting plate 6 with the limiting groove, and insert the end of the threaded rod 1 connected to the first connecting column 2 into the knob cover 3. One end of the threaded rod 1 abuts against the inclined surface of the arc-shaped clamping block 5. Continue to insert it with force, and the arc-shaped clamping block 5 moves into the annular cavity 8. The spring 4 contracts, and the arc-shaped clamping plate moves from the end of the threaded rod 1 away from the limiting ring 9 to the other side of the limiting ring 9. The first limiting plate 6 slides into the limiting groove;

[0025] The rectangular opening prevents the limiting ring 9 from obstructing the first limiting plate 6 and the rectangular block 7 , ensuring that the threaded rod 1 can be inserted into the knob cover 3 .

[0026] Furthermore, the rectangular block 7 is slidably connected to the limiting groove, a second limiting plate 10 is fixedly connected inside the knob cover 3 , and one end of the first connecting column 2 abuts against the second limiting plate 10 .

[0027] The second limiting plate 10 and the limiting ring 9 work together to limit the first connecting column 2 , thereby limiting the threaded rod 1 and preventing the knob cover 3 from falling off from one end of the threaded rod 1 .

[0028] Furthermore, one end of the first connecting post 2 is fixedly connected to the second connecting post 11 , one end of the second connecting post 11 is provided with a cross slot 12 , one end of the knob cover 3 is provided with a circular hole 13 , and the second connecting post 11 is located in the circular hole 13 .

[0029] The fastener is fastened by using a screwdriver and the cross slot 12 to cooperate with each other through the circular hole 13 .

[0030] Furthermore, a trapezoidal groove 14 is formed on the knob cover 3 , and a nut 15 is threadedly connected to the threaded rod 1 .

[0031] Among them, the trapezoidal groove 14 is convenient for the staff to screw the knob cover 3, and the nut 15 cooperates with the threaded rod 1 to fasten the objects on the support frame.

[0032] The working principle of this utility model:

[0033] When assembling the knob cover 3 and the threaded rod 1, the first limit plate 6 is aligned with the limit groove, and the end of the threaded rod 1 connected to the first connecting column 2 is inserted into the knob cover 3 until one end of the threaded rod 1 is against the inclined surface of the arc-shaped block 5. Continue to insert it with force, and the arc-shaped block 5 moves into the annular cavity 8. The spring 4 contracts until the arc-shaped block 5 is stuck from the end of the threaded rod 1 away from the limit ring 9 and into the other side of the limit ring 9 to complete the assembly. The knob cover 3 assembled at one end of the threaded rod 1 is not easy to slip when manually tightened, and the knob cover 3 using the trapezoidal groove 14 is more convenient to twist.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
