Normally, only two brackets (1 fixed bracket, 1 reinforced bracket) can be made on the surrounding structural parts, but the space is currently small, and only the wind guide plate (aluminum plate) can be used around, and the strength cannot meet the requirements; moreover, this bracket is relatively simple to connect with the aircraft parts themselves, and it is very easy for this bracket to fall off if it is simply fixed with bolts. Summary of the invention
[0003] The technical problem to be solved by the present invention is to provide an aircraft governor cantilever bracket that is easy to disassemble and assemble in view of the above-mentioned technical deficiencies. The cantilever bracket is fixed by using two bolt holes on the existing engine, and the other end of the cantilever bracket is used to fix the direction of the steel cable; and the bolt connection of the cantilever bracket is very stable, and the cantilever bracket is not easy to fall off.

DETAILED DESCRIPTION
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] like Figure 1-5 As shown, an aircraft speed governor cantilever bracket which is easy to disassemble and assemble comprises a connecting plate; a locking plate 1 is provided at the first end of the connecting plate 6; a first through hole 2 is penetrated through the locking plate 1 in the left-right direction; the number of the first through holes 2 is two; a limiting plate 3 is provided at the second end of the connecting plate 6; a second through hole 4 is penetrated through the limiting plate 3 in the left-right direction; a locking device is provided at the left part of the front end surface of the connecting plate 6 through a connecting rod.
[0020] The locking device comprises an intermediate gear 5 and a locking unit fixedly connected to the connecting rod; the number of the locking units is two; the locking units are meshed and connected through the intermediate gear 5. The two locking units are locked at the same time through the intermediate gear 5, which is convenient for disassembly and assembly.
[0021] The locking unit on the front side includes a sleeve 7 fixedly connected to the connecting rod; a locking cylinder 8 is sleeved on the inner side of the sleeve 7; a matching gear 9 is fixedly sleeved on the left part of the outer surface of the locking cylinder 8; a retaining ring 10 is fixedly sleeved on the left part of the inner side of the locking cylinder 8; the locking unit on the rear side has the same structure as the locking unit on the front side and is symmetrical from front to back; the matching gear 9 of the locking unit on the front side and the matching gear 9 of the locking unit on the rear side are both meshed with the intermediate gear 5. After the bolt enters the locking cylinder 8, the retaining ring 10 will limit the bolt, and when the bolt rotates, the bolt and the locking cylinder 8 can move simultaneously. The cross section inside the locking cylinder 8 is a hexagonal star, which can adapt to the shape of the nut part of the bolt so that the bolt can rotate.
[0022] A fixing column 11 is fixedly connected to the middle of the right end surface of the intermediate gear 5, and a labor-saving rod 12 is fixedly connected to the right end surface of the fixing column 11. The intermediate gear 5 can be rotated by rotating the labor-saving rod 12, so that the bolt can be rotated through the cooperation of the two matching gears 9, which is very labor-saving.
[0023] A circular groove 13 is provided at the right part of the rear end face of the connecting plate 6; a universal ball 14 is rotatably arranged in the circular groove 13; the outer side of the universal ball 14 is fixedly connected to the limiting plate 3; a jacking bolt 15 is provided at the right part of the front end face of the connecting plate 6; the rear end of the jacking bolt 15 is threadedly fitted through the right part of the front end face of the connecting plate 6 and extends into the circular groove 13. The universal ball 14 in the circular groove 13 will not naturally escape from the circular groove 13, and the circular groove 13 can restrict the universal ball 14 in the circular groove 13, but the universal ball 14 can also rotate in the circular groove 13, that is, the spatial angle and position of the limiting plate 3 can be adjusted, thereby adjusting the spatial angle and position of the rope, and then the universal ball 14 can be tightened with the jacking bolt 15 to fix the universal ball 14.
[0024] The upper end surface of the connecting plate 6 and the lower end surface of the connecting plate 6 are both fixedly connected with an arc-shaped reinforcing plate 16. The arc-shaped reinforcing plate 16 can strengthen the overall rigidity of the connecting rod.
[0025] When the present invention is used:
[0026] One end of the locking plate 1 is fixed to the two bolt holes of the original engine of the aircraft, and the speed governor cable passes through the second through hole 4 so that the speed governor cable is restricted on the restriction plate 3.
[0027] First, loosen the tightening bolt 15, rotate the universal ball 14, adjust the spatial angle and position of the limiting plate 3, pass the governor cable through the second through hole 4, lock the tightening bolt 15, tighten the universal ball 14, so that the universal ball 14 cannot rotate, and then put the two bolts into the locking cylinder 8, pass through the first through hole 2 and go deep into the bolt hole of the engine, turn the labor-saving rod 12 to rotate the intermediate gear 5, and the intermediate gear 5 drives the two matching gears 9 to rotate, that is, the two locking cylinders 8 rotate, and the locking cylinder 8 rotates with the bolts and screws them into the bolt holes.
[0028] During the bolt rotation process, the bolt will move toward the bolt hole. Due to the restriction of the retaining ring 10, the bolt will move the locking tube 8 toward the bolt hole, and finally tighten the bolt to fix the locking plate 1 on the original engine of the aircraft.
