[0020] A duct flange bolt fastening device close to a wall comprises a support rod 1, a rechargeable pistol drill 2, a pistol drill button 3, a visual probe 4, a placement rod 5 and a nut placement piece 6. The duct flange bolt fastening device close to the wall can be adjusted according to actual needs, so that the device can adapt to ducts of different sizes, thereby improving flexibility.

[0021] Among them: the support rod 1 is made of DN15 stainless steel pipe and is 1200mm long. The support rod 1 is a telescopic support rod. The front end of the support rod 1 uses a U-shaped pipe clamp to fix the rechargeable pistol drill 2. The rechargeable pistol drill 2 is relatively flexible and can adapt to various angles and narrow spaces, making the fastening operation more convenient. At the same time, no additional transmission parts are required, and the mechanical structure is relatively simple.

[0022] The switch control line of the rechargeable pistol drill 2 is connected and led out by an extension wire to the end of the support rod 1. The pistol drill button 3 is installed at the end of the support rod 1, and the pistol drill button 3 is connected to the switch of the rechargeable pistol drill 2 through the extension wire, which has good safety performance and low cost.

[0023] The placement rod 5 is made of a sleeve-type tightening galvanized steel conduit with a diameter of φ15mm and a length of 1200mm. Two open-end wrenches of different diameters are welded to the front end of the placement rod 5. The two open-end wrenches of different diameters include an open-end wrench with a diameter of 10mm and an open-end wrench with a diameter of 16mm. The open-end wrench with a diameter of 10mm is made of 25*2mm galvanized flat steel and has a diameter of 10mm and can pass through the duct flange bolt. The open-end wrench with a diameter of 16mm is made of 25*2mm galvanized flat steel and has a diameter of 16mm and can pass through the duct flange nut. Two open-end wrenches of different diameters are welded together in an arrangement in which the open-end wrench with a diameter of 10mm is at the bottom and the open-end wrench with a diameter of 16mm is at the top, and the whole after welding is connected to the placement rod 5.

[0024] The materials used in the utility model are all commonly used materials on construction sites, so no additional costs are required. On-site workers can complete the tightening of the flange bolts of the air duct close to the wall flange with handheld tools with guaranteed quality and quantity, thus avoiding rework and saving labor costs.

[0025] At the same time, in order to accurately place the nut through the placement rod 5 so that the duct flange bolt contacts the nut, a visualization probe 4 can be installed at the front end of the support rod 1, and the signal line of the visualization probe 4 passes through the inside of the support rod 1.

[0026] When the utility model is used, the duct flange bolts that need to be tightened are placed in the flange duct flange bolt holes close to the wall flange duct using the placing rod 5, and then the magnetic sleeve of the pistol drill 2 is tightly connected to the duct flange bolts through the visual probe 4 using the support rod 1, and the nuts are placed through the placing rod 5 so that the duct flange bolts are in contact with the nuts, and the duct flange bolts can be tightened by rotating the pistol drill 2.

[0027] The utility model can select different magnetic sleeves according to the different models of duct flange bolts and nuts, which greatly expands the scope of use. The use of the utility model can improve the construction efficiency and quality in narrow spaces and inconvenient operation areas. The utility model does not require excessive investment. On-site workers can complete the tightening of duct flange bolts close to the wall flange with handheld tools with guaranteed quality and quantity, avoiding rework and saving labor costs.
