For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0033] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] Combination Figure 2-Figure 4 As shown, this embodiment provides an auxiliary installation tool for a lateral fastener of an aircraft long stringer joint, which includes a first connecting portion 1, an extension portion 2, and a second connecting portion 3. Figure 2 and Figure 3 As shown, one end of the first connecting part 1 is provided with a connecting head 11 movably connected to the nail head of the fastener, one end of the extension part 2 is connected to the other end of the first connecting part 1 away from the connecting head 11, the extension part 2 is arranged at an angle with the first connecting part 1, one end of the second connecting part 3 is arranged at an angle on the circumferential side of the extension part 2, the axial direction of the second connecting part 3 is parallel to the axial direction of the first connecting part 1, the first connecting part 1 and the second connecting part 3 are in the same plane with the extension part 2, and the end of the rivet gun is movably connected to the other end of the second connecting part 3.

[0035] It can be understood that the connecting head 11 maintains a stable connection with the nail head of the fastener, that is, the two are always in the same axial direction, the other end of the first connecting part 1 facing away from the connecting head 11 is located outside the surrounding structure, and the extension part 2 extends in the direction away from the surrounding structure to transfer the position of the second connecting part 3 connected to the rivet gun to the outside of the surrounding structure. The auxiliary installation tool with an "L"-shaped structure can adapt to the narrow space for lateral fastener installation, avoiding position interference. When installing the fastener, the auxiliary installation tool can fully contact the nail head of the fastener, reducing the shaking when installing the fastener, and can effectively reduce the damage to the nail head of the fastener and the long beam joint, thereby improving the installation efficiency of the fastener.

[0036] Preferably, the axial direction of the first connecting part 1 of this embodiment is perpendicular to the axial direction of the extension part 2, and the axial direction of the second connecting part 3 is perpendicular to the axial direction of the extension part 2, that is, the angle between the two adjacent parts is 90°, which facilitates the conduction of force in the horizontal direction, so that the force applied by the rivet gun to the second connecting part 3 can be transmitted to the first connecting part 1 through the extension part 2 to act on the nail head of the fastener. The structure is simple and easy to manufacture.

[0037] In another embodiment, the angles between the axial direction of the first connecting portion 1 and the axial direction of the extension portion 2, and between the axial direction of the second connecting portion 3 and the axial direction of the extension portion 2 are obtuse angles, for example, 100°, 110°, 120°, 130°, 140° or 150°, etc. Of course, they can also be set at acute angles. This embodiment does not make specific limitations on this and can be set according to actual conditions, as long as the second connecting portion 3 is kept away from the surrounding structure by the extension portion 2 to avoid space limitation.

[0038] Furthermore, the first connection part 1, the extension part 2 and the second connection part 3 are integrally formed. One end of the extension part 2 is formed by bending to form the first connection part 1, and the second connection part 3 and the extension part 2 are cut to form. The integral forming has higher integrity and better strength.

[0039] In other embodiments, the second connection portion 3 and / or the second connection portion 3 may also be connected to the extension portion 2 by welding to facilitate processing and forming.

[0040] Furthermore, the first connection part 1, the extension part 2 and the second connection part 3 are made of metal materials. For example, the material of the present embodiment is stainless steel, which has the advantages of good corrosion resistance, light weight and portability, and easy cleaning. In other embodiments, it can also be iron or steel, etc., which is not specifically limited in the present embodiment.

[0041] In order to facilitate the operator to hold, such as Figure 2 and Figure 4 As shown, an arcuate transition surface 31 is provided at the connection between the extension portion 2 and the second connection portion 3. The base of the operator's thumb fits against the surface of the arcuate transition surface 31, making the grip more comfortable and convenient to apply force, thereby facilitating maintaining full contact between the connection head 11 and the nail head.

[0042] Specifically, Figure 2 As shown, the end of the connector 11 away from the first connector 1 is provided with a first connector groove 12 adapted to the nail head, the nail head of the fastener is movably inserted in the first connector groove 12 and abuts against the bottom wall of the first connector groove 12, and the end of the second connector 3 away from the extension 2 is provided with a second connector groove 32, the end of the rivet gun is movably inserted in the second connector groove 32 and abuts against the bottom wall of the second connector groove 32. The plug-in connection has good stability, ensuring that the axial direction of the nail head is coaxial with the first connector 1, and the end of the rivet gun is coaxial with the second connector 3, so that the horizontal force of the rivet gun can be fully transmitted to the connector 11.

[0043] More specifically, the connection point between the first connection part 1 and the extension part 2 is a, the connection point between the extension part 2 and the second connection part 3 is b, and the end of the extension part 2 away from the first connection part 1 is c. ab is defined as the length distance between a and b, and bc is the length distance between b and c, and ab≥bc. The length of ab can be set according to the specific length of the enclosing structure. In other embodiments, ab<bc may also be used.

[0044] In addition, in order to make the auxiliary installation tool adaptable to different surrounding structures, the length of ab is set to be adjustable. For example, a sleeve structure is set, and the depth of the sleeve connection can be adjusted, which has better versatility.

[0045] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
