[0003] 1. It is not convenient to align the roof hole with the floor installation hole: During the construction drilling process, the installation of the connection structure between the roof and the floor is often involved. In some cases, it is necessary to drill the floor first and then the roof. It is often difficult to accurately align the roof installation hole with the floor installation hole, which easily leads to the deviation of the drilling position from the predetermined position, causing unnecessary damage to the building structure, thus increasing the difficulty and risk of subsequent installation work;

[0061] In the technical field of construction tools, the performance of the roof opening tool is directly related to the improvement of the quality and efficiency of building structure installation. At present, the roof opening tool faces multiple limitations in application: First, it is difficult to achieve precise alignment between the roof opening and the floor installation hole, increasing the risk of drilling position deviation and affecting the structural stability; Second, the control of the drilling depth is not precise enough, easily resulting in over-depth or under-depth phenomena, which directly affects the stability of the installation components and the overall performance of the building; Moreover, the tool design is heavy and often uses an integrated design, which is inconvenient for disassembly and assembly and inconvenient to carry. Especially in high-altitude or narrow-space operations, its heaviness and integrated design significantly limit its applicability and exacerbate the operation difficulty and cost.

[0062] Please refer to Figures 1 to 7 , the embodiment of the present utility model provides a portable roof opening tool, including:

[0065] The first cross rod 30, the two ends of the first cross rod 30 are respectively detachably installed on the first vertical rod 10 and the second vertical rod 20, and are respectively rotationally connected to the first vertical rod 10 and the second vertical rod 20 to achieve flexible rotational operation. It is one of the components for forming the lever effect of the tool. An operation part 31 is extended at one end of the first cross rod 30 away from the second vertical rod 20, which is convenient for the operator to hold and control.

[0066] The second crossbar 40 is arranged in parallel with the first crossbar 30. The two ends of the second crossbar 40 are respectively detachably installed on the first vertical bar 10 and the second vertical bar 20, and are respectively rotationally connected to the first vertical bar 10 and the second vertical bar 20. The second crossbar 40, together with the first vertical bar 10, the second vertical bar 20 and the first crossbar 30, constitutes an adjustable square frame, enhancing the connection strength and adjustability of the overall structure of the tool, providing additional stability, and having a detachable installation structure, which is convenient for carrying and transportation and is less restricted by the working space.

[0067] The locking member 50 is used to lock the relative positions of the first crossbar 30 and the first vertical bar 10, ensuring that after the tool is adjusted, it maintains a stable working state during the operation process and preventing accidental folding, which may cause safety risks in the opening of the top plate.

[0068] The electric drill 60, as the core component for opening holes, is used to perform the hole-opening action.

[0069] The clamping member 70 is movably installed at the top end of the second vertical bar 20 and is used to clamp the electric drill 60, ensuring the stability and accuracy of the electric drill 60 during the operation process.

Through sensing technology, the position of the floor installation hole is accurately identified, and it is in sensing cooperation with the first sensing and positioning member 71, so that the axial position of the drill bit of the electric drill 60 is on the same axis as the position of the floor installation hole, ensuring the precise alignment of the position of the top plate drilling and the floor installation hole.

[0073] The control unit, as the intelligent control center of the tool, is used to control the start, stop, speed adjustment of the electric drill 60 and the lifting action of the lifting mechanism, and through the integrated control logic, an intelligent and controllable drilling operation process is realized.
