Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2The utility model provides an embodiment: a screw structure that is easy to install, including a screw 1, a screw 1 having a thread 2 on the outside, the screw 1 being the main body of the whole structure, and the thread 2 on the outside is used to be screwed with a matching nut or directly with the internal thread 2 of the part to be connected, so as to achieve the connection. The bottom end of the screw 1 is fixedly connected with a conical block 3, which helps to guide the screw 1 to enter the installation position smoothly during installation and provides a certain stability. The top of the screw 1 is fixedly connected with a nut 4, the inside of the nut 4 is provided with a through hole 11, and the inside of the nut 4 is fixedly connected with a push rod 5, the nut 4 is used as the connection point at the top of the screw 1, and the inside is provided with a through hole 11, and the through hole 11 is used to accommodate the push rod 5. The outside of the push rod 5 is fixedly connected with two connecting bolts 6, and the outsides of the two connecting bolts 6 are respectively rotatably connected with connecting rods 7, and the function of the push rod 5 is to transmit force during the installation process so that the screw 1 can be screwed in smoothly. The connecting bolt 6 is a hub connecting the push rod 5 and the connecting rod. The left side of the connecting rod 7 is fixedly connected to a rotating bolt 8. The connecting rod 7 and the rotating bolt 8 allow the entire structure to be fine-tuned within a certain range to adapt to different installation angles and positions. The external rotation of the rotating bolt 8 is connected to a connecting rod 9. The two connecting rods 9 are fixedly connected to the side close to each other. The combination of the connecting rod 9 and the connecting rod 10 further increases the adjustability and stability of the structure, ensuring that the screw rod 1 can smoothly enter the installation position during the installation process. A buffer component for shock absorption is provided at the top of the screw rod 1.

[0031] Reference Figure 3 The buffer assembly includes a nut 4, which serves as the base of the buffer assembly. An annular groove 12 is provided inside the bottom end of the nut 4, and the annular groove 12 is used to provide a stable movement space for the assembly. A spring 13 is provided inside the annular groove 12, and the spring 13 is used to provide a buffering effect when the screw 1 is screwed in or subjected to impact force. An extrusion plate 14 is slidably connected to the bottom end of the nut 4, and the function of the extrusion plate 14 is to move inward when the screw 1 is subjected to axial pressure, and compress the spring 13 to achieve a buffering effect. An outer limit ring 15 is fixedly connected to the outside of the extrusion plate 14, and the outer limit ring 15 prevents it from falling out of the nut 4 when subjected to excessive pressure. An inner limit plate 16 is fixedly connected to the inside of the extrusion plate 14 to ensure that the extrusion plate 14 slides stably inside the nut 4, while protecting the internal spring 13 from direct damage.

[0032] Reference Figure 1 , Figure 2 Figure 3The top of the conical block 3 is fixedly connected to the bottom of the screw 1. The conical block 3 helps to guide the screw 1 to enter the installation position smoothly and improves stability. The bottom end of the nut 4 is fixedly connected to the top of the screw 1. The nut 4 provides a connection basis for subsequent components. The adjacent side of the two connecting bolts 6 is fixedly connected to the outside of the top rod 5, and the outside of the top rod 5 is fixedly connected to the inside of the nut 4. The top rod 5 becomes the key node for force transmission. The outside of the two connecting bolts 6 is respectively connected to the connecting rod 7, and the outside of the two rotating bolts 8 rotates the inner wall of the connecting rod 7 respectively. The connecting bolts 6 and the connecting rod 7 further enhance the adjustability of the structure. The inner walls of the two connecting rods 7 are respectively in contact with the outside of the two connecting rods 9, and the front and rear sides of the connecting rod 10 are respectively fixedly connected to the adjacent side of the two connecting rods 9, ensuring the overall stability of the structure. The spring 13 is in contact with the inner wall of the top of the nut 4, and the bottom end of the connecting rod 9 is in contact with the top of the extrusion plate 14, transmitting the force to the extrusion plate 14, thereby compressing the spring 13 to achieve shock absorption. The outside of the outer limiting ring 15 contacts the inner wall of the nut 4, and the outside of the extrusion plate 14 is slidably connected to the inner wall of the nut 4, ensuring that the extrusion plate 14 can slide freely inside the nut 4 and ensures that it will not deviate from the predetermined position.

[0033] Working principle: When the screw 1 is fixed or disassembled with other objects, the connecting rod 10 is pulled, and the connecting rod 10 moves with the connecting rod 9, and the connecting rod 9 moves the connecting rod 7 on the rotating bolt 8, so that the connecting rod 7 rotates on the connecting bolt 6, and then the connecting rod 10 is rotated, and the connecting rod 10 moves with the push rod 5, and the push rod 5 rotates with the nut 4, and the nut 4 rotates with the screw 1, so that when the screw 1 is installed or disassembled, no special tools are required, and the screw 1 can be disassembled and installed, which reduces the requirements for tools and reduces the time for installation or disassembly.

[0034] When the extrusion plate 14 is subjected to force, the extrusion plate 14 will compress the spring 13, and at the same time will slide inside the nut 4 with the outer limit ring 15, and the spring 13 will resist the external force, thereby reducing damage to the nut 4 and reducing the loosening of the nut 4 caused by vibration, thereby maintaining the stability of the connection.
