[0027] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0028] For easier understanding, see Figure 1-Figure 7 In this embodiment: a portable floor drilling tool comprises a mounting frame 3, a first supporting tube 4 is arranged at the bottom of the mounting frame 3, a second supporting tube 5 is slidably connected to the outer wall of the first supporting tube 4, a first fixing bolt 8 is fixedly installed on the outer wall of the second supporting tube 5, and one end of the first fixing bolt 8 passes through the second supporting tube 5 and is supported on the outer wall of the first supporting tube 4, a sliding groove 6 is provided on one side of the outer wall of the first supporting tube 4 and the second supporting tube 5, a plurality of sliding rods 7 are slidably connected to the inner wall communicating with the first supporting tube 4 and the second supporting tube 5, a sliding handle 9 is arranged on the outer wall of the lowermost sliding rod 7, a fixing clamp 21 is fixedly connected to the outer wall of the uppermost sliding rod 7, a motor 1 is fixedly installed on the fixing clamp 21, and a drill bit 2 is fixedly installed on the output shaft of the motor 1;

[0029] The mounting frame 3 includes a transverse plate 31, a fixed tube 32, a spring 33, and a positioning plate 35. The bottom of the positioning plate 35 is fixedly connected to the spring 33. The bottom of the spring 33 is fixedly connected to one end of the fixed tube 32. The other end of the fixed tube 32 is fixedly connected to both ends of the transverse plate 31. The transverse plate 31 is fixedly connected to the outer wall of the first support tube 4.

[0030] It should be noted that the first fixing bolt 8 is tightened and fixed after the first support tube 4 and the second support tube 5 slide to a suitable height. The tool height can be freely adjusted according to the height of the floor. The inner wall connected to the first support tube 4 and the second support tube 5 has the function of a track and can slide through a plurality of sliding rods 7. The sliding groove 6 can slide through the fixing clamps 21 and the sliding handles 9 connected at both ends of the plurality of sliding rods 7. The plurality of sliding rods 7 have a transmission function. The sliding handles 9 are switches controlled by workers. The height can be adjusted by pushing the sliding handles 9 to drive the fixing clamps 21 connected to the sliding rods 7. The two positioning plates 35 are in direct contact with the bottom of the floor. By adjusting the positions of the two positioning plates 35, the positions where holes need to be drilled can be positioned. When the positioning plate 35 compresses the spring 33, the positioning tube 34 will slide toward the inner wall of the fixing tube 32 to prevent the positioning plate 35 from shifting under the supporting force of the spring 33.

[0031] In some embodiments, a scale 12 is formed on the outer wall of the second support tube 5 .

[0032] It should be noted that the floor slab is far away from the operators on the ground, and the staff cannot observe the depth of the drilling with the naked eye. In addition, the strength of the operators varies when drilling, so the depth of each drilling is difficult to guarantee. The depth of the drilling can be intuitively seen by the distance moved by the scale 12 at the joint between the sliding handle 9 or the sliding rod 7.

[0033] In some embodiments, the outer wall of the second support tube 5 is fixedly connected to a connecting frame 10, and the outer wall of the connecting frame 10 is movably connected to a plurality of support frames 11 through bolts. The support frame 11 includes a supporting foot rod 111, a sliding foot rod 112 and a second fixing bolt 113. The sliding foot rod 112 is slidably connected to the inner wall of the supporting foot rod 111, and the second fixing bolt 113 is fixedly installed on the outer wall of the supporting foot rod 111, and one end of the second fixing bolt 113 passes through the supporting foot rod 111 and is supported on the outer wall of the sliding foot rod 112.

[0034] It should be noted that a plurality of support frames 11 can be installed using the connecting frame 10, and the support frames 11 are installed on the connecting frame 10 using bolts. By adjusting the tightness of the bolts, the plurality of support frames 11 can be rotated to different angles and then fixed. The supporting foot rod 111 is used to ensure that the sliding foot rod 112 slides therein, and is fixed using the second fixing bolt 113, thereby achieving height adjustment.

[0035] In some embodiments, when a plurality of sliding rods 7 are connected, the stud 71 at one end of the sliding rod 7 is connected to the threaded hole 72 of another sliding rod 7 through a thread.

[0036] It should be noted that the plurality of sliding rods 7 are connected in the middle by studs 71 ​​and threaded holes 72, so that the plurality of sliding rods 7 can be easily disassembled from the bottom of the second support tube 5, thereby achieving portability.

[0037] In some embodiments, one end of the sliding handle 9 is fixedly connected to a positioning bolt 91 . The positioning bolt 91 is fixedly installed on the outer wall of the sliding rod 7 , and the positioning bolt passes through the sliding rod 7 .

[0038] It should be noted that, through the positioning bolt 91 , one end of the sliding rod 7 is supported on the inner wall of the first supporting tube 4 or the second supporting tube 5 , so that the sliding rod 7 is positioned to prevent the sliding rod 7 from sliding out from the bottom of the second supporting tube 5 .

[0039] In some embodiments, a positioning tube 34 is slidably connected to the inner wall of the fixing tube 32 , and the top of the positioning tube 34 is fixedly connected to the bottom of the positioning plate 35 .

[0040] It should be noted that when the first support tube 4 slides upward from the inner wall of the second support tube 5, the mounting frame 3 will move upward with the first support tube 4, the positioning plate 35 will be supported on the bottom of the floor slab where holes need to be punched, and the positioning tube 34 will slide toward the inner wall of the fixed tube 32 to avoid tilting of the support under the support of the spring 33, thereby ensuring that the support position is more precise and more secure.

[0041] Working principle: When using the tool, adjust the tightness of the bolts on the connecting frame 10 to rotate the supporting frames 11 to a suitable angle to achieve fixation, slide the sliding foot rod 112 on the inner wall of the supporting foot rod 111, adjust it to a suitable height and fix it with the second fixing bolt 113, the first supporting tube 4 slides upward from the inner wall of the second supporting tube 5 to a suitable height and fixes it with the first fixing bolt 8, and at the same time, the mounting frame 3 moves upward with the first supporting tube 4, so that the spring 33 and the positioning tube 34 are squeezed, and the positioning tube 34 slides toward the inner wall of the fixing tube 32. When the positioning plate 35 is supported by the spring 33, the position where the hole needs to be drilled at the bottom of the floor slab is positioned at the same time, and the fixing clamp 21 is driven by the sliding rod 7 to slide upward from the bottom of the second support tube 5, and a plurality of sliding rods 7 are sequentially connected through the studs 71 ​​and the threaded holes 72, and the sliding rod 7 equipped with the sliding handle 9 is placed at the lowest end, and the sliding handle 9 is pushed to drive the motor 1 to slide upward, so that the motor 1 drives the drill bit 2 to drill the floor slab, and the depth of the drilling hole is accurately controlled by the distance moved on the scale at the joint between the sliding handle 9 or the plurality of sliding rods 7;

[0042] The tool adopts a sliding and retracting design. The first support tube 4 can slide and retract along the inner wall of the second support tube 5 at the connection with the second support tube 5, the sliding foot rod 112 can slide and retract along the inner wall of the supporting foot rod 111, and several support frames 11 can be retracted inwardly through the movable bolts on the outer wall of the connecting frame 10, so as to achieve portability for easy movement or transportation.

[0043] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
