[0015] In order to better understand the purpose, structure and function of the utility model, the adjustable ceiling hole opening tool of the utility model is further described in detail below with reference to the accompanying drawings.

[0016] like Figure 1~Figure 4 As shown, an adjustable ceiling hole opening tool includes a support 1, an operating rod 2 is arranged above the support 1, a first telescopic rod 3 is slidably connected in the operating rod 2, a second telescopic rod 13 is slidably connected in the first telescopic rod 3, an impact drill 14 is fixedly connected to the upper end of the second telescopic rod 13, a rack is provided on the first telescopic rod 3 along the telescopic direction, a gear 7 cooperating with the rack is rotatably connected in the operating rod 2, the gear 7 is fixedly connected to the rotating shaft pivotally connected to the operating rod 2, one end of the rotating shaft is connected to the rocker 8 and the hand crank 6, adjustment holes 11 are provided at intervals on the first telescopic rod 3 along the telescopic direction, the second telescopic rod 13 is provided with fixing holes corresponding to the adjustment holes 11, the adjustment hole 11 is aligned with the fixing hole, a bolt 12 is inserted into the bolt and is locked and fixed with a nut.

[0017] like Figure 2 As shown, the support 1 has a trapezoidal cross-section and is arranged at the bottom of the operating rod 2. The material may be rubber. The operating rod 2 is a square tube and is sealed at the top and bottom. The material is steel. The first telescopic rod 3 has a square tube cross-section and is arranged in the operating rod 2. An observation groove is provided on the operating rod 2 along the telescopic direction, and a scale 4 is provided along the observation groove.

[0018] like Figure 3As shown, a level bubble 5 is provided on the rod body of the operating rod 2, and the material is metal. The hand crank 6 is connected with the rocker 8 and the gear 7 to form a set of travel system with the rack provided on the side of the first telescopic rod 3. The operating rod 2 is provided with a travel limiter 9 at the lower end of the rack to limit the lowest position of the telescopic first telescopic rod 3. Lubricating oil is applied to the position of the gear 7. The hand crank 6, the rocker 8 and the gear 7 are made of steel.
