This patent is only suitable for controlling the drilling depth on flat surfaces, and is not suitable for controlling the drilling depth on irregular surfaces such as curved surfaces. This makes it impossible for personnel to control the drilling depth on irregular surfaces, resulting in poor practical performance of the electric drill.

[0004] Furthermore, there are no stable positioning measures when personnel use electric drills to drill holes in irregular surfaces, which makes drilling very inconvenient and results in poor stability when personnel use electric drills. Utility Model Content

[0005] To address the above problems, this utility model provides a tooling for adjusting the depth of drilling irregular surfaces, thus solving the aforementioned issues.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a depth adjustment fixture for drilling irregular surfaces, including an electric drill and a drill bit connected to one side of the electric drill. The electric drill is provided with an external mounting ring, and a plurality of fixing frames are connected to one side of the mounting ring. Two adjustment plates are connected to one side of each of the fixing frames.

[0007] The mounting ring has several threaded holes on its outside. The threaded holes are internally threaded with positioning bolts. One end of the positioning bolt is connected to a limit block, and the outside of the positioning bolt is connected to a clamping block.

[0008] Preferably, a slot is provided on one side of the clamping block, and a limiting groove is provided on another side of the clamping block, wherein the limiting groove is rotatably connected to the limiting block.

[0009] Preferably, an adjustment groove is provided on one side of the adjustment plate.

[0012] Preferably, a threaded hole is provided on one side of the locking block, and a fixing bolt is provided on one side of the adjusting plate.

[0013] Preferably, the fixing bolt is threadedly connected to the threaded hole of the locking block, the fixing bolt passes through the adjustment groove of the two adjustment plates, and a nut is externally connected to the fixing bolt.

[0014] Preferably, one side of the adjustment frame is connected to several positioning blocks, and one end of each positioning block is an arc surface.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This application uses an installation ring to fix the tooling to the outside of the electric drill, and with the help of the adjustment frame and positioning block, the electric drill can stably drill holes in irregular surfaces such as curved surfaces. This solves the problem that there is no stable positioning measure when personnel use electric drills to drill holes in irregular surfaces, which makes drilling very inconvenient. It helps to improve the stability of personnel when using electric drills.

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] Please see Figures 1 to 7 A depth adjustment fixture for drilling irregular surfaces includes an electric drill 1 and a drill bit 2 connected to one side of the electric drill 1. The operator installs the drill bit 2 on the electric drill 1. Subsequently, the operation of the electric drill 1 will drive the drill bit 2 to rotate. At this time, the drill bit 2 contacts the object to be drilled, so that the drill bit 2 performs drilling work. The electric drill 1 is a known technology, and those skilled in the art can and should understand its specific function and structure, so it will not be described in detail here. The electric drill 1 is provided with an installation ring 3 on the outside. Several fixing frames 4 are connected to one side of the installation ring 3. Two adjustment plates 5 are connected to one side of each of the fixing frames 4.

[0029] The mounting ring 3 has several threaded holes on its exterior. The internal threads of the threaded holes are connected to positioning bolts 7. One end of the positioning bolt 7 is connected to a limit block 8. The external parts of the positioning bolt 7 are connected to a clamping block 9. When using the electric drill 1, the operator first puts the mounting ring 3 on the outside of the electric drill 1. Then the operator rotates the positioning bolt 7. Because the positioning bolt 7 is threadedly connected to the threaded holes of the mounting ring 3, the positioning bolt 7 will move inside the threaded holes when it rotates. Therefore, the positioning bolt 7 will drive the clamping block 9 to move, so that the clamping block 9 will clamp the electric drill 1. At this time, the mounting ring 3 is installed and fixed on the outside of the electric drill 1.

[0030] It is important to note that when the positioning bolt 7 rotates, it will also drive the limiting block 8 to rotate. At this time, the limiting block 8 will rotate in the limiting groove 11 of the clamping block 9. Therefore, the positioning bolt 7 will not drive the clamping block 9 to rotate when it rotates.

[0031] Of course, the clamping block 9 may rotate slightly. It should be further explained that when the clamping block 9 is close to the electric drill 1 and is about to contact it, the operator should manually straighten the clamping block 9. As the positioning screw 7 drives the clamping block 9 to continue to move, the slot 10 of the clamping block 9 will contact the outside of the electric drill 1. Then, continue to tighten the positioning bolt 7 to make the clamping block 9 tightly clamp the outside of the electric drill 1. At this time, the depth adjustment fixture is installed and fixed on the outside of the electric drill 1.

[0032] It should be further noted that after the depth adjustment fixture is installed and fixed, because the fixture is circular, the installed fixture is concentric with the drill bit 2, thereby ensuring the normal operation of the drill bit 2.

[0033] A slot 10 is provided on one side of the clamping block 9, and a limiting groove 11 is provided on one side of the clamping block 9. The limiting groove 11 is rotatably connected to the limiting block 8.

[0034] An adjustment groove 6 is provided on one side of the adjustment plate 5.

[0035] An adjustment frame 12 is provided on one side of the fixed frame 4, and several adjustment blocks 13 are connected to one side of the adjustment frame 12. The outside of the adjustment blocks 13 is connected to the inside of the fixed frame 4.

[0036] A locking block 14 is connected to one side of the adjusting block 13, and the locking block 14 is slidably connected between the two adjusting plates 5.

[0037] When the operator adjusts the drilling depth of drill bit 2, the operator loosens the connection between the nut and the fixing bolt 15. At this time, the adjusting block 13 can slide inside the fixing frame 4. Then the operator can adjust the position of the adjusting block 13 in the fixing frame 4, thereby adjusting the position of the adjusting frame 2 and the positioning block 16. The difference in distance between the positioning block 16 and the drill bit 2 after adjustment is the drilling depth.

[0038] Specifically, when the adjusting block 13 moves inside the fixed frame 4, it will drive the locking block 14 to move between the two adjusting plates 5. In addition, the adjusting block 13 will also drive the adjusting frame 12 and the positioning block 16 to move. When it moves to the appropriate position, the personnel will tighten the connection between the nut and the positioning bolt 7 to fix the locking block 14, so that the adjusting frame 12 and the positioning block 16 remain in a fixed position.

[0039] It should be noted that the positioning bolt 7 passes through the threaded hole on the locking block 14 and is threadedly connected to the threaded hole. Therefore, when the positioning bolt 7 is fixed to one side of the adjusting plate 5 by the nut, it will also fix the locking block 14.

[0040] A threaded hole is provided on one side of the locking block 14, and a fixing bolt 15 is provided on one side of the adjusting plate 5.

[0041] The fixing bolt 15 is threadedly connected to the threaded hole of the locking block 14. The fixing bolt 15 passes through the adjustment groove 6 of the two adjustment plates 5. The fixing bolt 15 is externally connected with a nut.

[0042] Several positioning blocks 16 are connected to one side of the adjustment frame 12. One end of the positioning block 16 is an arc surface. The arc surface on one side of the positioning block 16 makes the depth adjustment fixture suitable not only for drilling flat surfaces, but also for drilling irregular surfaces such as curved surfaces.

[0043] When using this utility model:

[0044] First, the operator installs drill bit 2 on electric drill 1. Then, the operation of electric drill 1 will drive drill bit 2 to rotate. At this time, drill bit 2 comes into contact with the object to be drilled, so that drill bit 2 can perform drilling work.

[0045] Secondly, when using the electric drill 1, the operator first places the mounting ring 3 on the outside of the electric drill 1, and then rotates the positioning bolt 7. Because the positioning bolt 7 is threadedly connected to the threaded hole of the mounting ring 3, the positioning bolt 7 will move inside the threaded hole when it rotates. Therefore, the positioning bolt 7 will drive the clamping block 9 to move, so that the clamping block 9 will clamp the electric drill 1. At this time, the mounting ring 3 is installed and fixed on the outside of the electric drill 1.

[0046] Then, when the operator adjusts the drilling depth of the drill bit 2, the operator loosens the connection between the nut and the fixing bolt 15. At this time, the adjusting block 13 can slide inside the fixing frame 4. Then the operator can adjust the position of the adjusting block 13 in the fixing frame 4, thereby adjusting the position of the adjusting frame 2 and the positioning block 16. The difference in distance between the positioning block 16 and the drill bit 2 after adjustment is the drilling depth.

[0047] Finally, after the depth adjustment fixture is installed and fixed, because the fixture is circular, the installed fixture is concentric with the drill bit 2, thereby ensuring the normal operation of the drill bit 2.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
