[0009] Beneficial effects:

[0010] The nut is inserted into the hole of the building, and then due to the effect of gravity, the nut will rotate downward along the axis, and then the bolt is inserted into the hole, and the bolt is tightened to complete the connection of the fastener. Existing nuts cannot be placed in some environments that are already sealed. The nut can be placed through the bolt hole to achieve the function of the original nut and is used to fasten parts. Nuts play a key role in fastening and connecting other parts or objects in mechanical manufacturing. It is usually used in conjunction with nuts and bolts to ensure that parts are firmly fixed together. This tightening effect not only improves the overall stability of the machine, but also makes the equipment more reliable during operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] In one embodiment, please refer to the attached drawings of the specification Figures 1-6 As shown, a nut fastening assembly of the present utility model includes a retaining piece 1 and a bolt 3 installed on the retaining piece 1. A through hole 6 is provided in the middle of the retaining piece 1. A plurality of support rods 2 are provided on one side of the retaining piece 1. A nut 4 is rotatably provided on the support rod 2. A screw hole 7 is provided on the nut 4. An external thread 5 is provided on the bolt 3. The bolt 3 passes through the inside of the through hole 6, and the external thread 5 is in screw fit with the screw hole 7.

[0021] The installation of the bolt 3 is supported by the provided retaining piece 1. During installation, the nut 4 is made flush with the support rod 2. When the nut 4 enters the interior of the wall, the nut 4 rotates around the support rod 2. Under the action of gravity, the nut 4 rotates downward along the axis. Then, the bolt 3 is inserted into the hole and the bolt 3 is tightened to complete the connection of the fastener. When the screw rod enters the interior of the nut 4, the screw rod is rotated to make the external thread 5 cooperate with the screw hole 7.

[0022] A limiting rod 15 is arranged on the supporting rod 2, and the limiting rod 15 is used to support the nut 4. The limiting rod 15 can ensure that when the nut 4 is inserted into the wall, the nut 4 will not rotate immediately, so that the nut 4 is stuck in other positions, making the nut 4 unable to continue to penetrate into the interior of the wall, thus unable to reach the specified position.

[0023] In one embodiment, please refer to the attached drawings of the specification Figures 3-5 As shown, a pull rod 10 is arranged inside the supporting rod 2, and the pull rod 10 slides inside the supporting rod 2. One end of the pull rod 10 is provided with a pull rope 14, one end of the pull rope 14 is provided with a pull ring 13, a connecting rod 12 is arranged on the nut 4, and the pull ring 13 is sleeved on the connecting rod 12. A rotating pin 11 is arranged on the nut 4, a supporting block 8 is arranged at the end of the supporting rod 2, a rotating hole 9 is arranged in the middle of the supporting block 8, and the rotating pin 11 is rotatably connected inside the rotating hole 9.

[0024] In order to better control the rotation of the nut 4, or in order to cope with the need for installation at an inclined angle; it is necessary to adjust the angle of the nut 4, not only relying on the self-gravity of the nut 4 to rotate, otherwise there will be an included angle between the nut 4 and the bolt 3, and the bolt 3 cannot enter the interior of the nut 4. When the nut 4 needs to be adjusted, the pull rod 10 is pulled, the pull rod 10 pulls the pull rope 14, the pull rope 14 pulls the pull ring 13, and the pull ring 13 is sleeved on the connecting rod 12. Therefore, when the pull rod 10 is pulled, the connecting rod 12 rotates around the rotating pin 11 until the connecting rod 12 rotates from the horizontal position to the vertical position. At this time, the nut 4 changes from horizontal to vertical, and the bolt 3 is inserted into the interior of the screw hole 7. The pull rope 14 is preferably made of polyethylene material, which is convenient for the pull rope 14 to break during the pulling process; the pull ring 13 arranged can be removed from the connecting rod 12, which is convenient for the repeated use of the bolt 3 and the nut 4. When the bolt 3 and the nut 4 are removed, only the pull ring 13 and the pull rope 14 need to be replaced to continue using.

[0025] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present invention. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
