[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0022] See also Figure 1 and Figure 2The utility model provides a rivet extractor for countersunk threaded hollow rivets, the rivet extractor for countersunk threaded hollow rivets comprises a pliers body 1 and a connector 2. The pliers body 1 comprises an upper body 11 and a lower body 12 which are rotatably connected, the upper body 11 is located at the top, and the lower body 12 is located at the bottom. The upper end of the connector 2 is detachably connected to the upper body 11, the middle part of the connector 2 is slidably connected to the lower body 12, and the lower end of the connector 2 has an external thread for connecting with the rivet.

[0023] When riveting, the lower end of the connector 2 is connected to the countersunk threaded hollow rivet, the middle part passes through the lower body 12, and the upper end is connected to the upper body 11. The upper body 11 can be rotated to drive the connector 2 to move upward, thereby performing riveting. The rivet extractor has a compact structure, which reduces the interference between the tool and the surrounding structure when constructing in the narrow space of an aircraft, thereby increasing applicability. The pliers body 1 reasonably utilizes the principle of leverage, making riveting more labor-saving.

[0024] In some embodiments, the end of the upper body 11 is a horn-shaped structure, and a groove is formed between the two horns of the upper body 11. The connecting member 2 can pass through the groove. The upper body 11 also abuts against the upper end of the connecting member 2, thereby driving the connecting member 2 to move upward when the upper body 11 is rotated.

[0025] In some preferred embodiments, the distance from one end of the upper body 11, where the connecting member 2 is located, to the rotation point is smaller than the distance from the other end to the rotation point. The other end is generally a gripping end, and the operator grips the other end to rotate the upper body 11. By increasing the length of the gripping end and using the steel rod to move away from the other end, the force during rotation can be reduced, which saves more effort when riveting.

[0026] In some embodiments, a circular through hole is formed at the end of the lower body 12, and the connecting member 2 passes through the through hole and is slidably connected to the through hole. The axis of the through hole is generally perpendicular to the lower surface of the lower body 12, and the through hole plays a guiding role to ensure that when the upper body 11 pulls up the connecting member 2, the connecting member 2 can move in a direction perpendicular to the lower surface of the lower body 12.

[0027] In some embodiments, the connector 2 includes a core rod 21, which is slidably connected to the through hole, and the core rod 21 and the through hole are gap-matched, and the gap between the two is as small as possible without affecting the sliding. The upper end of the core rod 21 also passes through the groove and is connected to the upper body 11.

[0028] In some embodiments, the connector 2 further includes a core head 22, which is detachably connected to the upper end of the core rod 21. The upper body 11 abuts against the core head 22, and the connector 2 is pulled up by the core head 22 when the upper body 11 rotates.

[0029] Preferably, an external thread is formed at the upper end of the core rod 21, and a threaded hole is correspondingly formed at the core head 22, and the core head 22 is threadedly engaged with the core rod 21.

[0030] In a preferred embodiment, the core head 22 is a nut, and the surface is processed by embossing process, which is convenient for disassembly and installation and improves processing efficiency.

[0031] In some embodiments, the connector 2 further includes a core rod 23, the upper end of which is detachably connected to the core rod 21, and the core rod 23 has an external thread, and the lower end of which is used to connect to a countersunk threaded hollow rivet.

[0032] Preferably, the upper end of the core rod 23 is formed with an external thread, and the lower end of the core rod 21 is correspondingly formed with a threaded hole, and the core rod 23 is threadedly engaged with the core rod 21. With a split design, different core rods 23 can be selected and replaced according to the rivet specifications, and the scope of use is wider.

[0033] In some embodiments, the connector 2 further includes a gasket 24, which is sleeved on the core rod 23 and located below the lower body 12. When riveting, the gasket 24 is located between the lower body 12 and the rivet to act as a buffer to prevent excessive local pressure.

[0034] Compared with the prior art, the rivet extractor provided by the utility model for countersunk threaded hollow rivets has a compact structure, reduces the interference between the tool and the surrounding structure during construction in the narrow space of an aircraft, and increases applicability. The pliers body reasonably utilizes the principle of lever, making riveting more labor-saving.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
