[0025] refer to Figures 1 to 4According to a preferred embodiment of the present invention, the structure of the perforator is as follows: Figure 1 and 2 As shown, specifically, the perforator structure includes an outer tube structure and an inner tube structure of the perforator, that is, it includes an outer tube body 10 and an inner tube body 20, wherein those skilled in the art should understand that the inner tube body 20 is arranged in the outer tube body 10.

[0026] Among them Figure 1 As shown, the outer tube body 10 has a first opening, a first cavity 101 and a second opening. The first opening and the second opening are both connected to the first cavity 101, and the first opening and the second opening are also connected to the outside. It should be noted that the wall forming the first cavity 101 has a first thread groove 102 and a second thread groove 103, which are arranged as shown in FIG. Figure 1 As shown, the first thread groove 102 is close to the first opening and is spaced a predetermined distance from the first opening, and the second thread groove 103 is close to the second opening and is spaced a predetermined distance from the second opening. It is worth mentioning that the above-mentioned first thread groove 102 and the above-mentioned second thread groove 103 are both used to cooperate with the remaining components of the perforator.

[0027] Furthermore, the outer wall of the outer tube body 10 has a plurality of spirally arranged first shooting holes 104 , and the plurality of first shooting holes 104 are all blind holes.

[0028] It should be noted that the inner tube body 20 also has a third opening, a second cavity 201, and a fourth opening. The third opening and the fourth opening are both connected to the second cavity 201, and the inner tube body 20 is placed in the first cavity 101. The outer wall of the inner tube body 20 has a plurality of spirally arranged second firing holes 202, and the plurality of second firing holes 202 correspond one-to-one to the plurality of first firing holes 104.

[0029] It should also be noted that the outer wall of the inner tube body 20 also has a plurality of evenly distributed mounting grooves 203, and the plurality of mounting grooves 203 are arranged opposite to the plurality of second firing holes 202, and the plurality of mounting grooves 203 are also connected to the second cavity 201, and the plurality of mounting grooves 203 also correspond one-to-one with the plurality of second firing holes 202. Specifically, each of the mounting grooves 203 has a connecting hole and two strip-shaped notches, the two strip-shaped notches are arranged opposite to each other and spaced a predetermined distance apart, the connecting hole is located between the two strip-shaped notches and is connected to the strip-shaped notches, wherein the shape of the mounting groove 203 is as follows: Figure 2As shown, and those skilled in the art should understand that, the above-mentioned connecting hole is used to connect the end of the external perforating bullet, and the connection method is implemented as a threaded connection. At the same time, the other end of the perforating bullet passes through the second shooting hole 202 and faces the second shooting hole 202 and the first shooting hole 104.

[0030] Furthermore, each of the first firing holes 104 has two oppositely arranged connecting grooves 204 on its circumference, wherein the structure is as follows: Figure 2 As shown, the two connecting grooves 204 are also connected to the second cavity 201 , and the two connecting grooves 204 are also connected to the corresponding second shooting holes 202 .

[0031] It should be noted that the end of the inner tube body 20 is configured to cooperate with the external connecting plate 30. Specifically, the external connecting plate 30 includes a plate body and an extension portion. The plate body is connected to the extension portion, and the extension portion also has an assembly hole 301 at the end away from the plate body. It should be noted that the previous cooperation method between the end of the inner tube body 20 of our company and the assembly hole 301 was welding. However, since the welding method has low processing efficiency and high cost, in order to reduce costs and increase efficiency, our company has made partial improvements to the structure of the inner tube body 20 and the connecting plate 30 to improve the convenience of assembly.

[0032] Furthermore, the end of the inner tube body 20 has a plurality of evenly distributed arcuate protrusions 21, which are arranged in a circular array, and preferably have a number of 6.

That is, when the ends of the arcuate protrusions 21 are deformed, the arcuate protrusions 21 and the strip grooves 302 are misaligned, thereby defining the position of the end of the inner tube body 20 and the connecting plate 30.

[0033] Specifically, each of the arc-shaped protrusions 21 has a long notch 2101 on one side, that is, the user can apply a force to the wall close to the long notch 2101 to cause this part of the wall to be deformed by the force, that is, this part is misaligned with the strip groove 302, thereby limiting the position of the connecting plate 30. Compared with the previous welding connection, this method has lower processing costs and is more convenient to install.
