Description

Technical Field

[0001] This utility model relates to the field of electric drill technology, specifically an electric drill with laser positioning and ranging functions. Background Technology

[0002] In fields such as construction and decoration, and furniture manufacturing, electric drills are essential tools, and the demand for operational efficiency is increasing. Traditional electric drills have shortcomings in terms of positioning accuracy and depth control, especially in confined spaces or high-precision operations, making it difficult to meet the needs of modern construction.

[0003] Currently, traditional electric drills lack reliable positioning and depth control mechanisms. Relying on manual marking can easily lead to positional deviations, and depth adjustment requires repeated measurements, resulting in low efficiency. Some improved models use fixed limiting structures, which are difficult to adapt to complex working conditions or the need for multiple drill bits. Maintenance requires complete disassembly, making the operation cumbersome. In view of this, we propose an electric drill with laser positioning and distance measurement functions.

[0024] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model proposes a hand drill with laser positioning and ranging functions, including a hand drill body 1. A laser emitting module 2 is fixedly connected to the inner wall of the hand drill body 1. The installation of a laser emitting module 2 on a hand drill is prior art and will not be described in detail. A connecting plate 3 is provided at one end of the hand drill body 1 near the output end. A positioning ring groove is formed on the output end of the hand drill body 1. When the hand drill body 1 is working, the output end will rotate, thereby driving the positioning ring groove to rotate. A connecting component 4 is provided on the outer wall of the connecting plate 3. The connecting component 4 includes a guide groove 4. 1. A guide groove 41 is provided on the upper part of the connecting plate 3. A guide rail 42 is slidably connected to the inner wall of the guide groove 41. A storage groove 43 is provided on the connecting plate 3. A limiting arc block 44 is fixedly connected to the outer wall of the guide rail 42. The limiting arc block 44 can be stored through the storage groove 43. An adjusting rod 45 is fixedly connected to the outer wall of the guide rail 42. The storage groove 43 and the limiting arc block 44 are elastically connected by a spring 46. An avoidance groove is provided on the connecting plate 3. The movement of the adjusting rod 45 is avoided through the avoidance groove. The avoidance groove is interconnected with the guide groove 41.

[0027] In this utility model, a dimension post 5 is slidably connected to the inner wall of the connecting plate 3, and an abutment plate 6 is fixedly connected to the end face of the dimension post 5. The dimension post 5 is provided with engraved length numbers and scale lines. An arrow indicator plate 7 is fixedly connected to the outer wall of the connecting plate 3. The arrow of the arrow indicator plate 7 points to the scale line, which makes it easy for us to confirm the position of the connecting plate 3, and then confirm the position of the electric drill body 1 connected to it.

[0028] Furthermore, a fixing post 8 is fixedly connected to the outer wall of the abutment plate 6. A flat surface is provided on the fixing post 8. A modular leveling seat 9 is snapped onto the abutment plate 6. One end of the modular leveling seat 9 is square and the other end is round. A snap-fit ​​hole is provided on the connecting plate 3. The round end of the modular leveling seat 9 can be snapped into the snap-fit ​​hole. The modular leveling seat 9 has various specifications. The round end has the same length, while the square end has different lengths.

[0029] Furthermore, a limit ring 10 is slidably connected to the outer wall of the fixing column 8, and an adjusting screw is threadedly connected to the inner wall of the limit ring 10. By tightening the adjusting screw, it abuts against the plane of the fixing column 8, thus completing the fixing of the limit ring 10. A fixing hole 11 is provided on the connecting plate 3, and a fixing screw is threadedly connected to the fixing hole 11. By tightening the fixing screw, it abuts against the plane of the fixing column 8, thus completing the fixing of the connecting plate 3.

[0030] In use, by moving the adjusting rod 45, the guide rail 42 is moved, causing the limiting arc block 44 to slide into the storage groove 43. This compresses the spring 46, making it easier for the output end of the electric drill body 1 to pass through the connecting plate 3. Then, the adjusting rod 45 is released, and the spring 46 returns to its original position, causing the limiting arc block 44 to slide towards the electric drill body 1. When the positioning ring groove on the electric drill body 1 moves to the limiting arc block 44, the limiting arc block 44 slides into the positioning ring groove, limiting the output end of the electric drill body 1 to the connecting plate. By moving the electric drill body 1, the connecting plate 3 can slide on the fixed column 8. The fixed column 8 and the dimension column 5 guide the movement of the connecting plate 3. When separation is required, by moving the adjusting rod 45, the guide rail 42 is moved, causing the limiting arc block 44 to leave the positioning ring groove, thus allowing the electric drill body 1 to leave the connecting plate 3 and complete the separation.

[0031] The distance measurement principle is as follows: After the connecting plate 3 is connected to the drill body 1, the connecting plate 3 is moved first to make the drill bit on the drill body 1 move synchronously, so that the head of the drill bit is flush with the contact surface of the contact plate 6. The value recorded by the arrow indicator plate 7 is recorded as A. Assuming we need to rotate 8 cm, A-8=B. At this time, we rotate the appropriate modular leveling seat 9 and lock it onto the contact plate 6. The length C of the modular leveling seat 9 is: B-thickness of the contact plate 6-thickness of the limiting ring 10=C. Note that the length C of the modular leveling seat 9 refers to the length of its square end. When the modular leveling seat 9... After the seat 9 is properly connected, we move the limiting ring 10 to abut against the modular leveling seat 9, and tighten the adjusting screw to abut against the plane of the fixing column 8, thus completing the fixing of the limiting ring 10 and fixing the position of the modular leveling seat 9. At this time, when the connecting plate 3 moves to the surface of the limiting ring 10, it means that the drill bit has reached the correct depth. At the same time, the connecting plate 3 is limited by the limiting ring 10 and cannot move to the first abutment plate 6, thus avoiding drilling too deep. In conjunction with the modular leveling seat 9, it can also prevent the limiting ring 10 from being deflected by the connecting plate 3, ensuring the accuracy of the drilling depth of the device.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
