Description

Technical Field

[0001] This utility model relates to the field of power tool technology, and in particular to a handheld power tool that is easy to assemble and carry. Background Technology

[0002] Handheld power tools are mechanized tools that are powered by an electric motor or electromagnet and drive the working head through a transmission mechanism. They are small in size and easy to operate by hand. They are characterized by their high portability and flexible operation, and are widely used in home, industry, construction, maintenance, DIY and other fields.

[0003] Existing power tools generally adopt a one-piece structure that cannot be disassembled and assembled, resulting in poor portability. When working outdoors or in confined spaces, the large size of the tools makes them difficult to disassemble or expand, leading to limitations in certain spaces and making them unusable.

[0004] An existing patent (publication number: CN216138853U) discloses a handheld power tool that clamps and connects a rotor module and an output shaft module within a housing for internal transmission. The rotor module, acting as a drive mechanism, drives the output shaft module to achieve clockwise or counterclockwise rotation of the workpiece mounted at the end of the output shaft. This device and method not only have a simple structure and good sealing effect, enabling rapid assembly and disassembly, but are also easy to maintain, effectively reducing equipment production costs and improving production efficiency.

[0005] To address the aforementioned issues, existing patents offer solutions, but they do not facilitate battery replacement. In practical use, the lack of a battery replacement mechanism limits the tool's battery life in outdoor power-free scenarios or during extended work periods. Furthermore, the inability to replace the battery leads to work stoppages, requiring the user to return for charging or carry multiple tools, increasing weight and cost, and impacting the operator's normal work. Therefore, this invention improves the practicality of the device.

[0006] Therefore, a handheld power tool that is easy to assemble and carry is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A handheld power tool that is easy to assemble and carry includes an operating handle 1, an output component 2 rotatably connected to the top of the operating handle 1, and a U-shaped mounting block 3 fixedly connected to the bottom of the operating handle 1. The output component 2 includes a mounting cylinder 201, a rotating motor 202 fixedly connected inside the mounting cylinder 201, and several heat dissipation holes 203 provided on the front and rear sides of the mounting cylinder 201. An electrode plate 4 is fixedly connected to the left side inside the U-shaped mounting block 3, and an energy storage component 5 is movably connected inside the U-shaped mounting block 3.

[0029] The energy storage component 5 includes a battery 501. A connector 502 is fixedly connected to the top of the battery 501, and the left side of the connector 502 is in close contact with the electrode plate 4. Slider 503 is fixedly connected to the front and rear sides of the connector 502. A movable plate 504 is movably connected to the right side inside the two sliders 503. A spring 505 is fixedly connected to the opposite side of the two movable plates 504, and a pressing block 506 is fixedly connected to the other end of the movable plate 504.

[0030] In this embodiment: By pressing the pressing block 506, the moving plate 504 moves smoothly within the slider 503 and compresses the spring 505, releasing the fixed state between the battery 501 and the connector 502. Simultaneously, under the action of the spring 505, a reaction force is generated, causing the moving plate 504 and the pressing block 506 to smoothly reset, allowing the connector 502 to precisely embed into the U-shaped mounting block 3 and form a tight contact with the electrode plate 4, creating a stable conductive path. This completes the efficient replacement of the battery 501, eliminating the need for charging and making it suitable for emergency repairs, field operations, and other situations without power. In the source scenario, the convenience of using the energy storage component 5 is improved. Then, through the cooperation of the storage cylinder 207 and the magnetic cover plate 208, the storage cylinder 207 can be opened flexibly, making it convenient to store and retrieve the tool drill bit without the need for an additional tool bag, which is convenient for operators to carry. At the same time, the rotating motor 202 drives the rotating rod 204 to rotate, which drives the tool mounting head 205 to rotate smoothly, thereby driving the tool drill bit to process. With the help of the heat dissipation hole 203, the rotating motor 202 can be cooled in time to ensure the stable operation of the device and improve the convenience of using the output component 2.

[0031] Specifically, such as Figure 5 As shown, the output end of the rotating motor 202 is fixedly connected to a rotating rod 204, and the other end of the rotating rod 204 extends to the left side of the mounting cylinder 201 and is fixedly connected to a tool mounting head 205. The front side of the tool mounting head 205 is threadedly connected to a bolt 206, and the rear side of the bolt 206 extends into the interior of the tool mounting head 205.

[0032] Specifically, such as Figure 5As shown, a storage cylinder 207 is fixedly connected to the right side of the mounting cylinder 201, a magnetic cover plate 208 is movably connected to the top of the storage cylinder 207, and several tool drill bits are placed inside the storage cylinder 207.

[0033] Specifically, such as Figure 2 , Figure 5 As shown, a fixing groove 6 is provided at the bottom of the storage cylinder 207, and a handle 7 is rotatably connected inside the fixing groove 6.

[0034] In this embodiment: by using the handrail 7 in conjunction with the fixing groove 6, the handrail 7 can rotate smoothly under the restriction of the fixing groove 6. This not only allows the handrail 7 to be stored, reducing the overall size of the tool and making it easier for the operator to carry, but also allows the handrail 7 to be unfolded as a second grip point, forming a two-hand grip mode with the main operating handle 1. This can disperse the reaction force when the tool is in operation and improve the stability of the tool.

[0035] Specifically, such as Figure 3 As shown, the front and rear sides of the inner wall of the U-shaped mounting block 3 are provided with sliding grooves 8 for use with the slider 503, and the surface of the slider 503 is in contact with the inner wall of the sliding groove 8. The right side of the front and rear sides of the U-shaped mounting block 3 are provided with positioning holes 9 for use with the pressing block 506, and the positioning holes 9 are connected to the sliding groove 8.

[0036] Specifically, such as Figure 4 As shown, both sliders 503 have a moving groove 10 on the right side inside for use with the moving plate 504, and the side of the spring 505 away from the moving plate 504 is fixedly connected to the side of the inner wall of the moving groove 10 near the connector 502. The right side of the slider 503 away from the connector 502 has a moving hole 11 for use with the pressing block 506, and the moving hole 11 is connected to the moving groove 10.

[0037] In this embodiment: the moving hole 11 is connected to the moving groove 10, so that the pressing block 506 drives the moving plate 504 to move smoothly under the restriction of the moving groove 10 and compress the spring 505, releasing the fixed state of the battery 501. At the same time, under the action of the spring 505, it generates a reaction force, driving the moving plate 504 and the pressing block 506 to reset, realizing the efficient replacement of the battery 501, eliminating the dependence on charging, and making it suitable for emergency repair and other scenarios, improving the convenience of using the energy storage component 5. Then, the positioning hole 9 is connected to the slide groove 8, so that the slider 503 moves smoothly under the restriction of the slide groove 8, and simultaneously drives the battery 501 and the connector 502 to move to the appropriate position, so that the pressing block 506 is accurately embedded in the positioning hole 9, realizing the tight connection between the battery 501 and the U-shaped mounting block 3, forming a stable conductive path, ensuring the stable operation of the device, and improving the convenience of using the device.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, spotlights 12 are fixedly connected to both the front and rear sides of the storage cylinder 207, and the spotlights 12 are electrically connected to the operating handle 1 and the battery 501.

[0039] Specifically, such as Figure 1 , Figure 2 As shown, several rubber rings 13 are embedded in the surface of the operating handle 1, and the surface of the rubber rings 13 is provided with anti-slip texture.

[0040] In this embodiment, the rubber ring 13 not only increases the friction between the rubber ring and the operator's hand, reducing the risk of slipping out of their hand, but also buffers some of the impact force, ensuring the stability of the device during operation and reducing hand fatigue. At the same time, under the effect of the spotlight 12, sufficient light can be provided to the processing area, allowing the operator to clearly observe the processing process and avoid processing errors caused by insufficient light. This comprehensively ensures the processing accuracy of the tool and improves the stability of the device.

[0041] Working Principle: When using the handheld power tool, first manually move the magnetic cover 208 to open the storage cylinder 207, allowing easy removal of the drill bit. Install the drill bit into the tool mounting head 205. After installation, rotate the operating handle 1 to a suitable angle for easy handholding. Then, manually press the block 506, causing the moving plate 504 to slide smoothly within the moving groove 10 inside the slider 503. Simultaneously, the spring 505 is compressed, quickly releasing the locking state of the battery 501 and connector 502. This allows the battery to move smoothly within the sliding groove 8 under the constraint of the slider 503. Simultaneously, the spring 505... This generates a reaction force, causing the moving plate 504 and the pressing block 506 to smoothly reset, allowing the pressing block 506 to be precisely embedded in the positioning hole 9. At the same time, the connector 502 is precisely embedded in the U-shaped mounting block 3 and forms a tight contact with the electrode plate 4, forming a stable conductive path. This completes the efficient replacement of the battery 501, eliminating the need for charging. It is suitable for emergency repairs, field operations, and other scenarios without power. After installation, the handle 7 is unfolded as a second grip point, forming a two-hand grip mode with the main operating handle 1. This can disperse the reaction force during tool operation. At the same time, by starting the rotating motor 202 with the operating handle 1, the rotating rod 204 and the tool drill bit are driven to rotate at high speed, achieving efficient processing.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
