The two limiting pieces 2 are respectively connected to the two sides of the hole making piece 1. The limiting piece 2 includes a fixing piece 21 and a horizontal connecting piece 22. The fixing piece 21 is connected to the aircraft skin. One end of the horizontal connecting piece 22 is rotatably connected to the fixing piece 21, and the other end is rotatably connected to the hole making piece 1. Since the horizontal connecting piece 22 always maintains a horizontal state, the hole making piece 1 can always be in a vertical state with the aircraft skin and in a vertical and close-fitting state with the rivet on the aircraft skin. The arrangement of the two horizontal connecting pieces 22 can ensure that the hole making piece 1 is stable under stress. Thus, the worker does not need to hold the hole making piece 1 when using the hole making piece 1 to drill the rivet, avoiding the problem of hand soreness after long-time work, and improving the efficiency of rivet removal. Meanwhile, the horizontal connecting piece 22 is rotatably connected to the fixing piece 21 and the hole making piece 1. Even if the fixing piece 21 is fixedly connected to the aircraft skin, the activity range of the hole making piece 1 can be ensured, and the drilling of the rivet head can be completed without frequently disassembling the fixing piece 21. The shape of the horizontal connecting piece 22 can be changed, which can further expand the activity range of the hole making piece 1 on the aircraft skin, realize the drilling of more rivet heads, and improve the convenience of the worker using the rivet removal auxiliary tool.

[0036] Exemplarily, the horizontal connecting piece 22 includes a plurality of joints 221, and the plurality of joints 221 are rotatably connected. Thus, the shape of the horizontal connecting piece 22 can be changed, and the activity range of the hole making piece 1 on the aircraft skin can be increased. The number of joints 221 can be adjusted, so that the length of the horizontal connecting piece 22 can be adjusted. The worker can adjust the number of joints 221 according to the area of the aircraft skin, and improve the flexibility of the rivet removal auxiliary tool.

Specifically, when the bone joint 221 is assembled, the protruding part 2212 and the mounting groove 22111 between adjacent bone joints 221 are connected by the pin shaft 3, that is, the adjacent bone joints 221 are connected by rotating the two adjacent bone joints 221 through the pin shaft 3 after the protruding part 2212 of the rear bone joint 221 is inserted into the mounting groove 22111 of the front bone joint 221. Among them, the bone joint 221 closer to the hole forming part 1 is the front bone joint 221. Specifically, a first mounting hole is arranged on the opposite side wall of the mounting groove 22111, and a second mounting hole is arranged on the protruding part 2212, and the pin shaft 3 penetrates the first mounting hole and the second mounting hole, so that the two bone joints 221 can be connected. Preferably, the protruding part 2212 is arranged integrally with the main body 2211, which not only ensures the stability of the structure of the bone joint 221, but also facilitates the processing of the bone joint 221.

[0038] Further, the center point of the mounting groove 22111 is located on the extension line of the center line of the protruding part 2212. In this way, the upper end face and the lower end face of the plurality of bone joints 221 in the horizontal connecting part 22 are in flush state, which ensures the stability of the horizontal connecting part 22, further ensures the stability of the hole forming part 1, and improves the service life of the horizontal connecting part 22.

[0041] The rivet removal auxiliary tool further comprises an elastic piece 4 which is vertically arranged between the first connecting column 121 and the horizontal connecting piece 22. Specifically, the second connecting column 122 penetrates the protruding portion 2212 of the bone joint 221 close to the guide body 11, when the hole making piece 1 moves, the second connecting column 122 can move in the second mounting hole of the protruding portion 2212 which is penetrated by the second connecting column 122, since the aircraft skin has a curved surface area, when the rivet on the curved surface area is punched, the worker can adjust the hole making piece 1 according to the curvature of the curved surface area, at this time, the height of the horizontal connecting piece 22 remains unchanged, with the adjustment of the hole making piece 1, the elastic piece 4 is compressed, under the action of the elasticity of the elastic piece 4, the hole making piece 1 can be always attached to the rivet, so that the stable placement of the hole making piece 1 on the curved surface area can be ensured, and the frequent replacement of the assembly position of the rivet removal auxiliary tool on the aircraft skin by the worker when the rivet on the curved surface area is punched is avoided, and the convenience of use of the rivet removal auxiliary tool is improved. The elastic piece 4 is vertically arranged between the first connecting column 121 and the horizontal connecting piece 22, which can further improve the stability of the force of the hole making piece 1 in the vertical direction of the surface of the aircraft skin.

[0042] As preferred, the elastic piece 4 can be a spring, the spring is sleeved on the outer periphery of the second connecting column 122, and at the same time abuts against the first connecting column 121 and the horizontal connecting piece 22, the second connecting column 122 can guide the spring, further ensuring the stability of the force of the spring in the compression process.

[0043] Further, the connecting piece 12 is arranged in the guide body 11 close to one end of the press-fitting groove 112, and the second connecting column 122 faces away from the press-fitting groove 112, so that the adjustment space of the hole making piece 1 in the height direction relative to the surface of the aircraft skin is sufficient, and the rationality of the design of the rivet removal auxiliary tool is improved.

[0044] In the embodiment, as shown in Figure 2 , Figure 5 and Figure 6As shown in the figure, the fixing member 21 comprises a first mounting part 211 and a second mounting part 212 which are opposite in the height direction, wherein the first mounting part 211 is used for connecting with the aircraft skin, and the second mounting part 212 is used for connecting with the horizontal connecting member 22, so that the horizontal connecting member 22 has a certain height relative to the surface of the aircraft skin, and the adjustment space of the hole forming member 1 in the height direction relative to the surface of the aircraft skin is ensured. Wherein, when the fixing member 21 is assembled, a rivet on the surface of the aircraft skin can be disassembled first, and an assembly hole is left on the aircraft skin, then the first mounting part 211 of the fixing member 21 is fixed with the assembly hole by using a fixing pin, and then the second mounting part 212 of the fixing member 21 is inserted into the mounting groove 22111 of the knuckle 221 assembled therewith, and the two are rotationally connected by using the pin shaft 3.
