[0002] Building decoration is the abbreviation of building decoration and renovation projects, among which building ceiling is an important part of building decoration projects. When installing the ceiling, the expansion screws and nuts on the screw rods cooperate with each other, and the expansion screws are opened by screwing the nuts. The screw rod installation in the construction stage of the building ceiling is mainly divided into two steps: drilling and fixing. The traditional way to install the ceiling screw rods is to stand on a stepladder or other climbing equipment, first drilling the holes and then using a handheld electric drill and a short socket wrench to fix the screw rod nuts. This method requires frequent climbing up and down or frequent movement of the climbing equipment, which cannot be operated continuously, is time-consuming and labor-intensive, has low safety and is not easy to carry.

[0003] At present, the commonly used method of installing ceiling screws is to stand on the ground manually, first use an electric drill with an extension rod and an electric drill bracket, and then use a socket wrench with an extension rod to perform remote drilling and tighten the nuts of the screws respectively. Although this method does not require frequent movement and climbing of climbing equipment, which improves safety, since each set of tools in this method is a tool with a single function and the extension rod of each set cannot be extended, two sets of tools still need to be carried during ceiling construction, which occupies a large area and is inconvenient to carry and store. In addition, since a socket can only be adapted to a nut of one size, when there are many models of ceiling nuts, the number of sockets that need to be carried or replaced will increase, and the socket and the top of the extension rod are generally connected by screws. External tools are still needed for replacement and disassembly, which is not easy to disassemble and assemble. The overall problem is single functionality, inconvenient carrying and inconvenient disassembly. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to explain the technical content, purpose and effect of the present invention in detail, the following is a description of the embodiments and the accompanying drawings. It should be noted that the words "upper", "lower", "front" and "back" used in the following description refer to the attached drawings. Figure 5 and Figure 8 In the directions, the words "bottom" and "top" refer to the Figure 5 The direction towards the geometric center of a specific component.

[0029] The most critical concept of the present invention is that: through the upper sleeve 5, the upper fastening groove 7, the lower fastening groove 8, the lower sleeve 6, the connecting pipe 4, the upper internal thread groove 9 and the lower internal thread groove 10, the connecting pipe 4 only needs to be turned 180 degrees to realize the function of quickly disassembling and replacing sleeves 1 of different models and tightening screw nuts of various sizes and models; through the upper internal thread groove 9, the external thread block 14 of the extension rod 3, the lower internal thread groove 10 and the external thread block 14 of the vertical plate 13, the function of quickly assembling and disassembling the electric drill bracket 2 and the extension rod 3 is realized; by setting the extension rod 3 as a telescopic structure, the storage space is reduced and the portability is facilitated; by setting the horizontal plate 12 and the vertical plate 13 to be rotatable and foldable, the space occupied by the electric drill bracket 2 is reduced and the overall portability is improved; by fixing the assembly, the connection stability between the electric drill and the electric drill bracket 2 is improved;

[0030] The utility model integrates the functions of electric drilling and tightening a variety of different types of screw nuts. The overall structure is simple and the replacement and assembly are convenient. It avoids the inconvenience of carrying multiple sleeves 1 separately or the inconvenience of using external tools to disassemble and assemble the sleeve 1. It occupies a small area and has the advantages of being multifunctional, easy to carry and easy to assemble and disassemble.

[0031] Please refer to Figures 1 to 10 As shown, a sleeve 1 for a ceiling screw is provided. The sleeve 1 includes a connecting pipe 4, an upper sleeve 5 and a lower sleeve 6. The upper sleeve 5 is fixedly connected to the upper side of the connecting pipe 4, and the lower sleeve 6 is fixedly connected to the lower side of the connecting pipe 4. The top surface of the upper sleeve 5 is provided with an upper fastening groove 7, and the bottom surface of the lower sleeve 6 is provided with a lower fastening groove 8. The upper fastening groove 7 and the lower fastening groove 8 are respectively used to socket screw nuts of different types. The top end of the connecting pipe 4 is provided with an upper internal thread groove 9 for threaded installation of the power drill bracket 2, and the bottom end of the connecting pipe 4 is provided with a lower internal thread groove 10 for threaded installation of the extension rod 3. The upper internal thread groove 9 and the lower internal thread groove 10 are arranged in mirror symmetry.

[0032] A tool for installing a ceiling screw comprises an electric drill bracket 2, an extension rod 3 and a sleeve 1. The electric drill bracket 2 comprises a horizontal plate 12, a vertical plate 13 hinged at one end to one end of the horizontal plate 12, a locking mechanism 15 for locking the vertical plate 13 and the horizontal plate 12, and a fixing assembly for fixing the electric drill. The top of the extension rod 3 and the bottom of the vertical plate 13 are both connected to an external thread block 14 that cooperates with the upper internal thread groove 9 and the lower internal thread groove 10; the extension rod 3 is a telescopic structure.

[0033] From the above description, it can be seen that when it is necessary to install a screw on a suspended ceiling or other distant wall, first, use the fixing assembly to fix the electric drill on the horizontal plate 12 and the vertical plate 13 to prevent the electric drill from shaking, thereby ensuring the stability of the connection between the electric drill and the electric drill bracket 2; then, through the upper internal thread groove 9, the vertical plate 13 and the external thread block 14, the external thread block 14 of the vertical plate 13 with the electric drill fixed is tightened into the upper internal thread groove 9, thereby achieving the effect of quickly loading and unloading the electric drill bracket 2 and the sleeve 1; then, through the lower internal thread groove 10, the extension rod 3 and the external thread block 14, the external thread block 14 at the top of the extension rod 3 of the corresponding length is tightened to the lower internal thread groove The threaded groove 10 allows for quick assembly and disassembly of the extension rod 3 and the sleeve 1; by holding the extension rod 3, move the sleeve 1 and the electric drill bracket 2 together toward the position where a hole needs to be drilled on the ceiling or a distant wall, start the electric drill, and unscrew the electric drill bracket 2 from the upper internal threaded groove 9 after the electric drill completes drilling. In addition, through the locking mechanism 15, since one end of the vertical plate 13 is hinged to one end of the horizontal plate 12, it is only necessary to open the locking mechanism 15 and rotate the vertical plate 13 around one end of the horizontal plate 12 toward the horizontal plate 12 until the vertical plate 13 is rotated to fold and overlap with the horizontal end, thereby reducing the footprint of the electric drill bracket 2 and improving overall portability.

[0034] Afterwards, if the model of the screw nut to be installed matches the size of the upper fastening groove 7 of the upper sleeve 5, the corresponding screw is directly inserted into the upper sleeve 5, and the screw nut is sleeved in the upper fastening groove 7. The extension rod 3 is held and the sleeve 1 is sent to the hole to be installed in the ceiling or the distant wall. After the expansion screw of the screw is pushed into the hole, the extension rod 3 is rotated to continuously tighten the nut so that the top of the expansion screw expands and the screw is fastened in the hole. If the nut of the screw to be installed matches the lower sleeve 6, First, loosen the connecting tube 4, unscrew the extension rod 3 from the lower internal thread groove 10, then turn the connecting tube 4 180 degrees so that the lower sleeve 6 faces upward, and then tighten the external thread block 14 of the extension rod 3 into the upper internal thread groove 9. Repeat the above steps of tightening the screw rod to achieve the function of tightening screw nuts of various types; because the upper sleeve 5 and the lower sleeve 6 are fixedly installed on the connecting tube 4, there is no need to carry multiple sleeves 1 separately. The threaded disassembly and assembly are convenient for replacement and assembly.

[0035] Furthermore, the bottom end of the upper sleeve 5 and the top end of the lower sleeve 6 are provided with a limit groove 11 for placing the lead screw; each of the upper fastening groove 7 and the lower fastening groove 8 is provided with at least one, and they are respectively communicated with the limit groove 11 of the upper sleeve 5 and the limit groove 11 of the lower sleeve 6, and the upper fastening grooves 7 and the lower fastening grooves 8 are connected to each other, and the dimensions between the upper fastening grooves 7 are arranged to decrease from top to bottom toward the direction of the limit groove 11 of the upper sleeve 5, and the dimensions between the lower fastening grooves 8 are arranged to decrease from bottom to top toward the direction of the limit groove 11 of the lower sleeve 6.

[0036] From the above description, it can be seen that by setting the number of upper fastening grooves 7 and lower fastening grooves 8 to at least one, the tightening of screw nuts of different sizes and specifications is increased; when the number of upper fastening grooves 7 and lower fastening grooves 8 are both greater than two, because the size between the upper fastening grooves 7 decreases from top to bottom toward the limit groove 11, it is convenient for screw nuts of different sizes to enter the matching upper fastening groove 7 without hindrance. Similarly, because the size between the lower fastening grooves 8 decreases from bottom to top toward the limit groove 11, it is also convenient for screw nuts of different sizes to enter the matching lower fastening groove 8 smoothly, increasing the number of types of screw nut sizes and models that the overall sleeve 1 is adapted to, thereby achieving the function of tightening screw nuts of multiple different sizes and specifications; the limiting groove 11 is provided to facilitate the screw screw to be limited through the upper sleeve 5 or the lower sleeve 6.

[0037] Furthermore, a vertical distance between the top end of the upper sleeve 5 and the bottom end of the lower sleeve 6 is greater than a vertical distance between the top end and the bottom end of the connecting pipe 4 .

[0038] From the above description, it can be seen that the vertical connection distance between the top end of the sleeve 1 and the bottom end of the lower sleeve 6 is set to be greater than the vertical connection distance between the top end and the bottom end of the connecting tube 4. When the screw nut is rotated and tightened, it is avoided that the two ends of the connecting tube 4 protrude and interfere with the use of the upper sleeve 5 and the lower sleeve 6.

[0039] Furthermore, the upper sleeve 5 and the lower sleeve 6 are both located on the same side of the connecting pipe 4; the upper sleeve 5 and the lower sleeve 6 are communicated with each other and are integrally formed.

[0040] It can be seen from the above description that by providing the upper sleeve 5 and the lower sleeve 6 as an integral molding, the connection stability between the upper sleeve 5 and the lower sleeve 6 is improved.

[0041] Furthermore, each of the upper sleeve 5 and the lower sleeve 6 is provided with one, the upper sleeve 5 is fixedly connected to the upper section of one side surface of the connecting pipe 4, and the lower sleeve 6 is fixedly connected to the lower section of the other opposite side surface of the connecting pipe 4.

[0042] As can be seen from the above description, the upper sleeve 5 and the lower sleeve 6 are respectively arranged on opposite sides of the connecting pipe 4 to balance the stability of the overall weight of the sleeve 1.

[0043] Furthermore, the connecting pipe 4 includes a horizontal pipe 35 and a vertical pipe 36 arranged in a cross shape, and the upper internal thread groove 9 and the lower internal thread groove 10 are respectively provided at the two ends of the vertical pipe 36, and the two ends of the horizontal pipe 35 are also respectively provided with an upper internal thread groove 9 and a lower internal thread groove 10, the upper sleeve 5 and the lower sleeve 6 are respectively fixedly connected to the upper section and the lower section on the same side of the vertical pipe 36, and the two ends of one side of the horizontal pipe 35 are respectively fixedly connected with a front sleeve 37 and a rear sleeve 38, and the opposite ends of the front sleeve 37 and the rear sleeve 38 are respectively provided with a front fastening groove 39 and a rear fastening groove 27 matching different types of screw nuts; the vertical connection distance between the opposite ends of the front sleeve 37 and the rear sleeve 38 is greater than the vertical connection distance between the two ends of the horizontal pipe 35.

[0044] From the above description, it can be seen that through the upper sleeve 5, the lower sleeve 6, the front sleeve 37, the rear sleeve 38, the horizontal tube 35 and the vertical tube 36 arranged in a cross shape, the size and type of the screw nuts to be tightened that the sleeve 1 as a whole is adapted to are further expanded, thereby further increasing the number of size and type of screw nuts that the sleeve 1 is adapted to.

[0045] Furthermore, the upper end surface of the horizontal plate 12 is provided with a groove 16 for folding and storing the vertical plate 13, and a group of fixing plates 17 for limiting the two sides of the bottom of the electric drill are installed in the groove 16. The fixing assembly includes a group of positioning rods 18, a side pressure plate 19 located between the fixing plates 17, and an upper pressure plate 20 installed at the other end of the vertical plate 13. The lower end of the side pressure plate 19 is provided with a grip limit hole 21. One end of the positioning rod 18 is fixedly connected to both sides of the side pressure plate 19; the other end of the positioning rod 18 slides through the vertical plate 13 in turn and is connected to a push rod 20. Plate 22, the vertical plate 13 is extended with a support 23, and the support 23 is rotatably penetrated by a screw 24; one end of the screw 24 is threaded through the push plate 22 and is rotatably connected to the vertical plate 13, and the other end is connected to the crank 25; the upper pressure plate 20 is provided with a drill rod limiting hole 26, the upper pressure plate 20 and the side pressure plate 19 are both provided with rubber pads, the vertical plate 13 is provided with a makeshift groove 28 for accommodating the fixed plate 17 and the side pressure plate 19, the vertical plate 13 is provided with a through hole for the fixed plate 17 to pass through, and the horizontal plate 12 is provided with a makeshift hole for the upper pressure plate 20 to pass through.

[0046] From the above description, it can be seen that when the electric drill needs to be fixed, the bottom of the electric drill is first placed on the horizontal plate 12. First, a set of fixing plates 17 are used to limit the two sides of the bottom of the electric drill to prevent the electric drill from shaking and affecting the drilling accuracy, thereby playing a role in preliminarily fixing the electric drill; then, through the side pressure plate 19, the positioning rod 18, the push plate 22, the support 23, the screw 24 and the crank 25, the crank 25 is manually turned first, and the screw 24 rotates, driving the push plate 22 to move toward the direction close to the vertical plate 13, thereby driving the positioning rod 18 and the side pressure plate 19 to move away from the vertical plate 13. Until the push plate 22 contacts the vertical plate 13, the upper end of the electric drill is passed between the side pressure plate 19 and the vertical plate 13, so that the side of the electric drill away from the handle contacts the vertical plate 13, and then the crank 25 is rotated in the opposite direction. The screw 24 rotates, driving the side pressure plate 19 to move toward the vertical plate 13 until the side pressure plate 19 presses the electric drill tightly against the side of the vertical plate 13. That is, the side pressure plate 19 limits and presses the electric drill in the lateral direction, playing a secondary role in fixing the electric drill; the handle limiting hole 21 is used to limit the bottom handle, playing a tertiary role in fixing the electric drill;

[0047] The upper pressing plate 20 and the drill rod limiting hole 26 are used to limit the drill rod and the electric drill vertically, thereby playing the role of four fixed limits on the electric drill; by arranging rubber pads on both the upper pressing plate 20 and the side pressing plate 19, it is convenient to fill the gap between the electric drill and the upper pressing plate 20, as well as the gap between the side pressing plate 19 and the electric drill, and at the same time, increase the friction between the upper pressing plate 20 and the side pressing plate 19 on the electric drill, thereby further improving the clamping force of the side pressing plate 19 and the upper pressing plate 20; through the groove 16 and the clearance groove 28, the floor space occupied by the horizontal plate 12 and the vertical plate 13 after folding and storage is further reduced, thereby further improving the convenience of overall storage and carrying, and achieving multiple fixing of the electric drill as a whole while improving the overall portability; when folding the horizontal plate 12 and the vertical plate 13, the through hole and the clearance hole are used for the fixing plate 17 to rotate through the vertical plate 13 and the upper pressing plate 20 to rotate through the horizontal plate 12, respectively, thereby further reducing the volume of the electric drill bracket after folding and storage.

[0048] Furthermore, a threaded rod 29 for measuring the drilling depth is provided at the top of the other end of the vertical plate 13, and a connecting portion 30 is extended outward from the top of the other end of the vertical plate 13. The connecting portion 30 is provided with a threaded hole 31 for the threaded rod 29 to be threaded through; there are multiple threaded holes 31, and the sizes and specifications are different.

[0049] From the above description, it can be seen that when it is necessary to control the target drilling depth of the electric drill, the threaded rod 29 of corresponding size is threaded into the threaded hole 31 of corresponding size, and the height difference between the top of the threaded rod 29 and the top of the drill rod of the electric drill is adjusted so that the top of the threaded rod 29 is lower than the top of the drill rod of the electric drill by a certain height. This height is the target drilling depth of the drilling. When drilling, when the top of the threaded rod 29 contacts the ceiling panel or the corresponding distant wall, the drilling depth of the electric drill reaches the target drilling depth, thereby realizing the function of controlling the drilling depth and improving the accuracy of the drilling depth.

[0050] Furthermore, an externally threaded column 32 is provided at the top of the externally threaded block 14 of the vertical plate 13. The diameter of the externally threaded column 32 is larger than the diameter of the externally threaded block 14. The top of the externally threaded column 32 is fixedly connected to the bottom of the vertical plate 13. The outer cover of the electric drill bracket 2 is provided with an ash collecting hopper 33 with an upward opening. The bottom of the ash collecting hopper 33 is provided with a connecting thread groove 34 for threaded connection of the externally threaded column 32.

[0051] From the above description, it can be seen that when the electric drill is drilling, the ash hopper 33 is used to collect the debris falling from the drilling to avoid the debris splashing, thereby realizing the function of collecting the drilling debris; through the external thread column 32 and the connecting thread groove 34, when the ash hopper 33 needs to be disassembled, first unscrew the external thread block 14 of the vertical plate 13 from the upper internal thread groove 9 or the lower internal thread groove 10, and then rotate the ash hopper 33 downward until the external thread column 32 is separated from the connecting thread groove 34, and the electric drill bracket 2 and the external thread block 14 are taken out from the upper end opening of the ash hopper 33 together, and the ash hopper 33 can be disassembled.
