It further includes a tool 101, which has a corresponding control part 102 (as shown in Figures 34 to 36). The corresponding control part 102 of the tool 101 can correspond to the tool control part 10 and is used to control the rod 12 of the connecting structure 1 (as shown in Figure 40). The tool control part 10 is formed by the space on both sides of the connecting body 13 that is lower than the upper end of the head 11 and located inside the head 11. Please refer to Figure 41. As shown in the figure, in this embodiment, the head 11 is injection molded using a mold 20, which can be used for plastic injection, metal injection, or non-metal injection. The mold 20 has a sprue 201, a gate 202, an upper mold 203, and a lower mold 204. There is a mold fitting portion 205 between the upper mold 203 and the lower mold 204, so that the liquid raw material enters the hollow head space 206 in the mold through the gate 202 and is cooled and solidified to form the head 11. Please refer to Figures 42 and 43. As shown, the present invention is a connecting structure 1, which includes at least: a head 11, a rod 12, and a connecting body 13. The connecting body 13 combines the head 11 and the rod 12. In addition to the above embodiments, in one embodiment of the present invention, the rod 12 is provided with a stop portion 125, the rod 12 passes through the head 11 and is stopped at the bottom of the head 11 by the stop portion 125.

In this way, the head 11 and the rod 12 can be stably combined. When in use, force can be applied to the head 11, causing the head 11 to engage the buckle 121 of the rod 12 with the desired object; when it is to be removed, force is applied to the head 11 in the opposite direction, causing the head 11 to engage the buckle 121 of the rod 12 with the desired object, thus achieving the effects of quick engagement and easy disengagement. In addition to the embodiments described above, in one embodiment of the present invention, a plurality of rods 12 are provided, each rod 12 being assembled with at least one mating portion 127, and the mating portions 127 being fixed to each other with a set of connectors 13. This allows the plurality of rods 12 to be assembled to form the rod 12. Furthermore, in other possible embodiments, the head 11 may also be assembled with one of the rods 12 using the at least one mating portion 127. Based on the above embodiments, in the assembly method of the assembly structure of the present invention, one of the rods 12 that is not assembled into the rod body 12 (i.e., the rod 12 with the stop portion 125 and the pressing portion 126) can be passed through the through portion 111, so that the pressing portion 126 is pressed against the inner edge of the through portion 111, and the rod 12 is passed through the through portion 111, so that the pressing portion 126 is pressed against the inner edge of the through portion 111, and the stop portion 125 is stopped at the bottom of the head 11. Then, the rods 12 are respectively combined with the assembly body 13 by the mating portion 127 to form the rod body 12. In addition to the above embodiments, in the assembly method of the assembly structure of the present invention, the rods 12 can be first assembled with the assembly body 13 by the mating part 127 to form the rod 12, and then the rod 12 is inserted into the through part 111, so that the pressing part 126 is pressed into the inner edge of the through part 111, and the rod 12 is inserted into the through part 111, so that the pressing part 126 is pressed into the inner edge of the through part 111, and the stop part 125 is stopped at the bottom of the head 11. In addition to the embodiments described above, in one embodiment of the present invention, the connecting portions 127 may be cylindrical or perforated, and the connecting bodies 13 may be bolts. This allows the rods 12, when assembled to form the rod body 12, to better meet the needs of practical applications. In addition to the above embodiments, in one embodiment of the present invention, the head 11, the rod 12 and the connecting body 13 may be a buckle, a metal structure, a riveted body, a welded body, an expansion body or a locking body, a metal material without heat treatment or a metal material with heat treatment. In addition to the embodiments described above, in one embodiment of the present invention, the connecting bodies 13 respectively pass through the mating portions 127 of the two rods 12, and are expanded and assembled by applying pressure to the connecting bodies 13 with a tool 5. In this way, the rods 12 can be stably assembled to form the rod 12. Please refer to Figures 44 to 46. As shown, in one embodiment of the present invention, in addition to the above embodiments, there is a floating amount 'a' between the connecting bodies 13 and the mating portions 127. This floating amount is 0.0001 mm to 5 mm. The connecting bodies 13 are deformed by the pressure applied by the tool 5, causing the connecting bodies 13 and the mating portions 127 to abut or press against each other, thereby filling, reducing, or reducing the floating amount 'a'. In this way, a plurality of rods 12 can be assembled by the cooperation of the connecting bodies 13 and the mating portions 127 to form the rod 12, and the rod 12 can achieve the effect of structural stability. In addition to the embodiments described above, in one embodiment of the present invention, the connecting bodies 13 and the mating portions 127 are made of metal or a deformable material. Thus, by utilizing the material properties of the connecting bodies 13 and the mating portions 127, the floating amount 'a' can be filled, reduced, or reduced to zero, and a plurality of rods 12 are assembled by the cooperation of the connecting bodies 13 and the mating portions 127 to form the rod 12. Alternatively, the connector 13 can also be integrally formed with the head 11 or the rod 12. In addition to the embodiments described above, in one embodiment of the present invention, the expansion and deformation of the connecting bodies 13 causes the floating amount a to be filled, reduced, or returned to zero (as shown in FIG44), or the expansion and deformation of the connecting bodies 13 and the shortening of the floating amount cause the floating amount to be filled, reduced, or returned to zero (as shown in FIG45). In this way, a plurality of rods 12 can be assembled to form the rod 12 by the cooperation of the connecting bodies 13 and the mating portions 127. In addition to the embodiments described above, in one embodiment of the present invention, the connecting bodies 13 expand and deform to fill the mating portions 127, thereby reducing the floating amount a to zero (as shown in FIG46). Thus, a plurality of rods 12 can be assembled by the cooperation of the connecting bodies 13 and the mating portions 127 to form the rod 12. In addition to the above embodiments, in one embodiment of the present invention, the connecting body 13 is pressed by the tool 5, and the connecting body 13 is deformed by the pressure, so that the connecting body 13 abuts, presses, or supports the head 11 or the rod 12, so that the floating amount a between the connecting body 13 and the head 11 or the rod 12 is filled, reduced, or returned to zero, or the floating amount a between the head 11 and the rod 12 is filled, reduced, or returned to zero, or the floating amount a between the rod 12 and another rod is filled, reduced, or returned to zero. Please refer to Figures 47 to 49. As shown in the figures, in one embodiment of the present invention, in addition to the above embodiments, the head 11 is disposed on the outer side of the rod 12. A plastic outer layer 171 is disposed on the outer side of the head 11, and a material inlet 18 is disposed near the head 11. The material of the head 11 is squeezed into the material inlet 18 by the pressing part 126 (or a portion of the material of the head 11 is squeezed into the material inlet 18 by the pressing part 126), wherein the hardness of the pressing part 126 is greater than the hardness of the head 11. In addition to the above embodiments, in one embodiment of the present invention, the width of the head 11 is smaller than the width of the plastic outer layer 171, so as to define a gap space s. When the pressing part 126 of the rod 12 enters the head 11, the gap space s is used to prevent the rod 12 and the plastic outer layer 171 from interfering with or blocking each other. In addition to the above embodiments, in one embodiment of the present invention, the surface of the pressing part 126 is provided with an anti-slip structure 1261 (or a stop structure). The plastic outer layer 171 can be formed by in-mold injection molding of plastic in the mold 20 and bonded to the head 11. The anti-slip structure 1261 (or the stop structure) is used to prevent the plastic outer layer 171 from rotating or moving between the head 11 after it is cooled from the liquid state to the solid state in the mold 20; thereby allowing the plastic outer layer 171 to be firmly bonded to the head 11. In addition to the above embodiments, in one embodiment of the present invention, the head 11 is formed by placing two molds 20 on both sides. Each of the molds 20 is provided with a plastic forming part and a plastic forming part 23 that can communicate with each other. After the molds 20 are combined, liquid plastic enters the plastic forming part 23 through the flow path 22, so as to cover the head 11 with the two sides attached (or cover the head 11 with the two sides) after the liquid plastic cools into a solid state. The present invention has been disclosed above with reference to preferred embodiments. However, those skilled in the art should understand that these embodiments are merely illustrative of the invention and should not be construed as limiting its scope. It should be noted that all variations and substitutions equivalent to these embodiments should be considered within the scope of the present invention.
