DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] The middle wire double-layer positioning type guide wire eyelet die 2 comprises a die sleeve 1, one end of the die sleeve 1 is recessed to form a containing groove 13, the other end is provided with a guide hole 14 which has a smaller diameter than the containing groove 13 and is communicated with the containing groove 13, and a limiting surface 15 is formed between the guide hole 14 and the containing groove 13; the eyelet die 2 is provided with a wire guide hole 21, one end of the eyelet die 2 is a wire inlet end 23, and the other end is a wire outlet end 22; after the eyelet die 2 is embedded into the containing groove 13, the wire inlet end 23 is abutted against the limiting surface 15, and the wire outlet end 22 is completely located in the containing groove 13; a locking abutting piece 3 is detachably installed at the end of the die sleeve 1 far away from the guide hole 14, and the locking abutting piece 3 is provided with an abutting part 31 abutting against the wire inlet end 23, and the locking abutting piece 3 is provided with a avoiding hole 33 corresponding to the wire guide hole 21.

[0024] It can be understood that the containing groove 13 is a structure for containing and limiting the eyelet die 2, for example, the eyelet die 2 and the containing groove 13 are both cylindrical or square columnar, but are not limited thereto. The limiting surface 15 is a component for abutting against the eyelet die 2, for example, can be a plane or a conical surface 25, but is not limited thereto. The locking abutting piece 3 is a component for extruding and fixing the eyelet die 2 in the containing groove 13, for example, the detachable installation of the locking abutting piece 3 can be screw connection, buckle connection, magnetic attraction, but is not limited thereto, the abutting of the abutting part 31 and the eyelet die 2 can be rigid abutting or elastic abutting, and the elastic abutting can be used in cooperation with springs or rubbers.

[0025] In this way, during installation, the wire outlet hole of the eyelet die 2 is aligned with the containing groove 13 and embedded into the containing groove 13, then the locking abutting piece 3 is installed on the die sleeve 1 and the abutting part 31 is abutted against the wire inlet end 23 of the eyelet die 2, so that the eyelet die 2 is stably fixed in the containing groove 13. When the eyelet die 2 needs to be replaced, the locking abutting piece 3 is removed, and the eyelet die 2 is poured out. Since the eyelet die 2 is clamped at both ends in the containing groove 13, the eyelet die 2 can be effectively prevented from rotating when the guide wire is inserted into the transmission.

[0026] In some embodiments, the eyelet die 2 is cylindrical in shape, the outer circle of the eyelet die 2 close to the wire outlet end 22 is a conical surface 25, and the conical surface 25 is provided with a concave-convex matching structure for preventing the eyelet die 2 from rotating after abutting against the limiting surface 15. Here, the concave of the concave-convex matching structure can be located on the conical surface 25, and the convex is located on the limiting surface 15, of course, the concave can also be located on the limiting surface 15, and the convex is located on the conical surface 25. For example, the concave-convex matching structure can be an axle hole matching structure, or a prismatic conical surface 25 can be arranged on the conical surface 25, and a prismatic groove which matches the prismatic conical surface 25 is arranged on the limiting surface 15. In this way, after the eyelet die 2 is embedded into the containing groove 13 and the wire outlet end 22 is abutted against the limiting surface 15, the eyelet die 2 will not rotate due to the cooperation of the concave-convex matching structure.

[0027] Preferably, the part of the sleeve 1 close to the accommodating groove 13 is a connecting part 12, and the part close to the leading hole 14 is an acting part 11, the outer wall of the connecting part 12 is provided with threads, and the diameter of the acting part 11 is greater than that of the connecting part 12. It can be understood that the acting part 11 is a part for contacting force during installation, for example, it can be a screw cap or a disc-shaped hand switch, but is not limited thereto. In this way, by screwing the acting part 11, the connecting part 12 is rotated and then threaded on other structures.

[0028] In some embodiments, the locking abutting part 3 further comprises a tightening part 32 installed at the end of the abutting part away from the eye module 2, and the abutting part 31 is threaded with the accommodating groove 13. Here, the tightening part 32 can be a screw cap or a keyway, but is not limited thereto. The abutting part is a long cylindrical structure with a threaded outer wall, and by screwing the tightening part, the abutting part is rotated into the accommodating groove 13, so that the abutting part abuts against the wire inlet end 23 of the eye module 2. The whole installation is stable and convenient to disassemble and assemble.

[0029] In some embodiments, the wire hole 21 is coaxially provided with two spaced-apart middle wire holes 24, and the diameter of the middle wire hole 24 is smaller than that of the wire hole 21. The middle wire hole 24 can accurately limit and guide the guide wire, and further, the inner ring part of the middle wire hole 24 is made of ceramic material, which has the advantages of high wear resistance and corrosion resistance, thereby improving the overall service life of the eye module 2.

[0030] In some embodiments, when the guide wire is inserted into the eye module 2 for transmission, heat will be generated due to friction. In order to ensure the stability of the guide wire during transmission, a cooling circulation groove 4 is arranged around the outer ring of the accommodating groove 13 in the sleeve 1, and the cooling circulation groove 4 is open at the head and tail of the sleeve 1. It can be understood that, in use, the head and tail of the cooling circulation groove 4 can be connected with cooling liquid and a circulating pump, so that the cooling liquid flows in the circulation groove, thereby reducing the stability of the whole sleeve 1 and ensuring the stability of the guide wire during transmission.

[0031] The above is only a preferred specific embodiment of the present application; however, the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacements or changes to the technical scheme and the improved concept of the present application within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
