[0020] The following will describe in detail a specific embodiment of the present utility model in conjunction with the accompanying drawings. However, it should be understood that the protection scope of the present utility model is not limited by the specific embodiment.

[0021] Embodiment 1:

[0022] As Figures 1-3 shown, an auxiliary device for fire damper screw fastening installation in a narrow space includes an operation component and an auxiliary stability component. The operation component is a component for driving the rotation of a nut or a screw rod on one side, and the auxiliary stability component is a limiting component on the other side, that is, to prevent axial rotation on the other side. The operation component includes a long sleeve 1 and a long screw rod 2 built in the long sleeve 1. The lower end of the long screw rod 2 extends out of the long sleeve 1, and its upper end is connected to a sleeve linkage right-angle wrench 3. The end of the sleeve linkage right-angle wrench 3 is connected to a first wrench end 4. The auxiliary stability component includes a hand-held long rod 8, and a second wrench end 9 is provided on the hand-held long rod 8.

[0023] Specifically, the first wrench end 4 and the second wrench end 9 are socket wrench ends, and the socket wrench ends are strong magnetic socket wrench ends. The upper end of the long screw rod 2 is connected to the sleeve linkage right-angle wrench 3 through a threaded connecting rod 5, that is, the threaded connecting rod 5 is connected to the transmission rod in the sleeve linkage right-angle wrench 3 to be able to drive the rotation of the output end, so that the output end drives the first wrench end 4 to rotate. The sleeve linkage right-angle wrench 3 is stably connected to the upper end of the long sleeve 1 through a fixing member 6. The fixing member 6 is a fixing sleeve, and a locking bolt 7 is provided on it. The upper end of the long sleeve 1 has a through hole matching the locking bolt 7, and the locking bolt 7 is screwed into the through hole to lock and stabilize the sleeve linkage right-angle wrench 3.
