[0020] like Figures 1 to 7The figure shows a splicing fastener comprising a cylindrical main connecting support column 1. The outer cylindrical surface of the main connecting support column 1 is provided with an integrally formed fastening thread 2, which enables a screw-like connection. On the right side of the main connecting support column 1 is an integrally formed cylindrical splicing connection column 3, which serves as the main mating structure for the splicing connection. A cylindrical combination connection groove 4 is located at the center of the right end face of the splicing connection column 3, enabling side-on splicing installation and interlocking with multiple components at the fastening location. An integrally formed precision combination stabilizing column is located at the center of the left end face of the combination connection groove 4, enabling precise combination and connection with the mating structure. A tight combination connection groove is formed between the outer side of the precision combination stabilizing column and the combination connection groove 4, ensuring a sealed space within the structure. A right-facing precision stopper groove 5 is located on the front of the combination connection groove 4. To the left of the precision stopper groove 5 is a cylindrical main body mating connection groove 6, enabling precise connection with the splicing mating structure, making installation more convenient. The width of the precise positioning limit groove 5 is smaller than the diameter of the main body matching connection groove 6, so that the locking position has a more stable matching connection, ensuring that the installation operation during matching is more convenient. It can simultaneously meet the combined use of fastening connection and splicing matching during use. By providing a splicing matching structure at one end of the connecting main structure and quickly assembling by means of positioning, it is more convenient during installation, the overall safety during connection is better, and the assembly efficiency is higher. The inner position is provided with a sealed matching groove to ensure that it is easier to disassemble later. There is a certain anti-fitting space inside to ensure that the internal part will not be tightly connected due to rust during long-term use, which affects disassembly. This makes the disassembly and assembly operation during maintenance more convenient and has a wider range of applications.

[0021] Preferably, a guide matching connection arc surface 7 is provided on both sides of the right side of the positioning precision limit groove 5, so that the combination is smoother during matching and the matching connection efficiency is higher.

[0022] Preferably, the depth of the combined connection fitting groove 4 is greater than two-thirds of the length of the splicing connection fitting column 3, so that the fitting strength during the splicing connection is higher and the internal fitting stability can be better.

[0023] Preferably, the connection position between the splicing connection matching column 3 and the main connection support column 1 is provided with an integrally formed reinforced stabilizing matching structure, so that the strength of the overall structure is higher and the durability of the connection position is better.

[0024] Preferably, the positioning precision limit groove 5 and the main body matching connection groove 6 are composed of a plurality of numbers evenly distributed around the circumference, and can be flexibly selected according to needs during matching, which can make the overall use range wider.

[0025] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles described in the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
