Description

Technical Field

[0001] This utility model relates to the field of screwdrivers, specifically a screwdriver with a built-in illuminated screwdriver shaft. Background Technology

[0002] In daily screw installation and removal work, whether it's simple furniture assembly and repair in a home environment or professional scenarios such as industrial production and equipment maintenance, insufficient lighting is a frequent problem. Traditional screwdrivers only have a single tightening function and do not have a lighting device. When working with screws in dimly lit areas, such as narrow corners, behind furniture, or inside machinery, users often need to use additional lighting tools such as flashlights to illuminate the work area.

[0003] However, using additional lighting tools presents several inconveniences. Firstly, if operated by a single person, one hand must hold the screwdriver while the other holds the flashlight. This not only increases the difficulty of operation and reduces work efficiency but also makes it difficult to ensure stability and accuracy, potentially leading to problems such as slipping screws or damaging workpieces. Secondly, in some special working environments, it may be impossible to simultaneously hold a lighting tool with one hand, further limiting the smooth progress of the work.

[0004] Furthermore, even in some work scenarios where screw operations can be completed with auxiliary lighting, the difficulty in precisely matching the lighting angle and position with the screwdriver's operating point can easily create shadows, affecting the operator's accurate judgment of the screw and screw hole positions, thus causing work difficulties. Therefore, to improve the convenience, accuracy, and efficiency of screw operations in low-light environments, we propose a screwdriver with a built-in lighting screwdriver handle. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a screwdriver with a built-in illuminated screwdriver handle, thus solving the aforementioned problems.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a screwdriver with a built-in lighting screwdriver handle, including a handle, a mounting platform provided at one end of the handle, a rod assembly inserted into the handle, the rod assembly including a locking platform and a rod body, a locking platform inserted into the mounting platform, a rod body inserted into the locking platform, the rod body being fixed to the locking platform by a locking structure, and one end of the rod body extending into the handle, two lights being equidistantly arranged at the end of the locking platform, and a contact switch being provided on the end face of the handle corresponding to the inner side of the mounting platform, the contact switch being electrically connected to the lights.

[0007] Preferably, the inner wall of the mounting platform is provided with an inner wall groove, and multiple sets of springs are fixedly installed on the bottom inner wall of the inner wall groove. The side of the insertion locking platform is integrally formed with an annular protrusion at the position of the inner wall groove. The annular protrusion is slidably engaged with the inner wall groove. The annular protrusion is fixedly connected with the springs. The bottom of the insertion locking platform is fixedly installed with a compression structure.

[0008] Preferably, the cross-section of the plug rod is rectangular, and multiple sets of triangular notches are equidistantly provided on the outer side of the plug rod corresponding to the position of the locking structure, and the locking structure engages with the corresponding triangular notches.

[0009] Preferably, the locking structure includes a locking block, a slider, and a second spring. At least one rectangular groove communicating with the interior is provided on the mounting platform. An inner wall groove is provided on the inner wall of the rectangular groove. The second spring is fixedly installed inside the inner wall groove. The locking block is inserted into the interior of the rectangular groove. Sliders are integrally formed on both sides of the locking block corresponding to the positions of the inner wall groove. The sliders are slidably engaged with the inner wall groove, and the inner wall groove is fixedly connected to the second spring.

[0010] Preferably, the lower end of the locking block is tapered.

[0011] Preferably, the threaded ring has an inclined pressing surface on one side of the locking block, and the locking block has an arc-shaped transition surface at the corner of the side corresponding to the inclined pressing surface.

[0012] Compared with the prior art, this utility model provides a screwdriver with a built-in lighting screwdriver shaft, which has the following beneficial effects:

[0013] Convenient lighting: The built-in light automatically turns on during use, providing immediate illumination to the work area. When the plug-in rod is aligned with the screw and pressed, the plug-in locking platform contacts the switch, and the light illuminates. Unlike traditional screwdrivers, there is no need for additional lighting equipment in low-light environments, avoiding the inconvenience of operating a screwdriver with one hand and holding a flashlight with the other, effectively improving the convenience and efficiency of operation.

[0014] Precise lighting angle: The light is set at the end of the plug-in locking platform, close to the working end of the plug-in rod. The lighting direction is directly aimed at the screw and closely fits the operating point, which can effectively reduce the generation of shadows and allow users to clearly see the position of the screw and screw hole. This allows for more accurate alignment of the screwdriver with the screw, greatly improving the accuracy of operation and reducing the risk of screw slippage and damage to the workpiece.

[0015] The structure is robust and adjustable: the rectangular cross-section of the connector rod ensures a stable fit with the locking platform, preventing wobbling. Simultaneously, the extension / retraction length of the connector rod can be flexibly adjusted via the locking mechanism and threaded ring. The locking block in the locking mechanism engages with the triangular notch on the connector rod, ensuring the rod will not accidentally retract during use; when length adjustment is needed, simply rotating the threaded ring easily unlocks and locks it, adapting to screw operation scenarios of varying depths.

[0016] Simple to operate: The entire operation process is simple and easy to learn. Simply press the screwdriver to turn on the light, and easily adjust the length of the connector by rotating the threaded ring. No complicated operating steps or additional tools are required, and both professional repair personnel and ordinary users can quickly master the operation method.

[0017] Safe and reliable: The design of spring one and spring two not only ensures the normal triggering of the lighting lamp and the stable locking of the plug rod, but also buffers the pressure during operation to a certain extent, avoiding tool damage or accidental injury caused by excessive force, thus improving safety and reliability during use.

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 Figure 1-6 A screwdriver with a built-in illuminated screwdriver handle includes a handle 1. A mounting platform 2 is provided at one end of the handle 1. A rod assembly is inserted into the handle 1, including a locking platform 3 and a rod 6. The locking platform 3 is inserted into the mounting platform 2, and the rod 6 is inserted into the locking platform 3. The rod 6 is fixed to the locking platform 3 by a locking structure, and one end of the rod 6 extends into the handle 1. Two lights 5 are equidistantly arranged at the end of the locking platform 3. A contact switch 11 is provided on the inner side of the mounting platform 2 corresponding to the end of the handle 1. The contact switch 11 is electrically connected to the lights 5. When using this device, if the end of the rod 6 is aligned with the screw and squeezed, the rod 6 will press against the locking platform 3, causing the locking platform 3 to contact the contact switch. At this time, the lights 5 are turned on, illuminating the end of the rod 6 and providing a light source.

[0027] Furthermore, the inner wall of the mounting platform 2 is provided with an inner wall groove 7. Multiple sets of springs 10 are fixedly installed on the bottom inner wall of the inner wall groove 7. An annular protrusion 8 is integrally formed on the side of the insertion locking platform 3 at the position of the inner wall groove 7. The annular protrusion 8 is slidably engaged with the inner wall groove 7. The annular protrusion 8 is fixedly connected with the springs 10. A pressing structure 9 is fixedly installed at the bottom of the insertion locking platform 3. When the springs 10 rebound normally, there is no contact between the springs 10 and the contact switch 11. When in use, the springs 10 need to be pressed when rotating the screw, so the springs 10 and the contact switch 11 will contact each other and activate the lighting lamp 5.

[0028] Furthermore, the cross-section of the plug-in rod 6 is rectangular, and multiple sets of triangular notches 18 are equidistantly provided on the outer side of the plug-in rod 6 at the position corresponding to the locking structure, and the locking structure engages with the corresponding triangular notches 18.

[0029] Furthermore, the locking structure includes a locking block 14, a slider 15, and a second spring 16. The mounting platform 2 has at least one rectangular groove 12 that communicates with its interior. The inner wall of the rectangular groove 12 has an inner wall groove 13. The second spring 16 is fixedly installed inside the inner wall groove 13. The locking block 14 is inserted into the interior of the rectangular groove 12. The two sides of the locking block 14 are integrally formed with sliders 15 corresponding to the positions of the inner wall groove 13. The sliders 15 are slidably engaged with the inner wall groove 13, and the inner wall groove 13 is fixedly connected with the second spring 16. When the second spring 16 rebounds normally, the lower end of the locking block 14 is not engaged with the triangular notch 18 on the insertion rod body 6.

[0030] Furthermore, the lower end of the locking block 14 is tapered.

[0031] Furthermore, the threaded ring 4 is provided with an inclined pressing surface 17 on one side of the locking block 14, and the corner of the locking block 14 corresponding to the inclined pressing surface 17 is provided with an arc-shaped transition surface. When it is necessary to adjust the extension length of the plug-in rod 6, the plug-in rod 6 is pulled out. After the length adjustment is completed, the threaded ring 4 is rotated so that the threaded ring 4 moves closer to the locking block 14. At this time, the inclined pressing surface 17 fits against the transition surface of the locking block 14, pressing the locking block 14. The locking block 14 moves closer to the interior of the plug-in locking platform 3, and then the second spring 16 retracts. Then the lower end of the locking block 14 is inserted into the triangular notch 18 at the corresponding position to complete the locking. When it is necessary to disassemble the plug-in rod 6, the threaded ring 4 is rotated and the threaded ring 4 moves away from the locking block 14. At this time, the inclined pressing surface 17 no longer presses the locking block 14, the second spring 16 rebounds, and then the locking block 14 is no longer engaged with the triangular notch 18, releasing the lock.

[0032] Structural Description:

[0033] Handle 1: This is the main part where the user holds and operates the screwdriver. A mounting platform 2 is located on one end of the handle, inside which the screwdriver assembly is inserted. The screwdriver assembly includes an insertion locking platform 3 and an insertion screw 6.

[0034] Mounting platform 2: Located at one end of the handle 1, it is the mounting point for the entire screwdriver shaft assembly. Its inner wall has an inner wall groove 7, and multiple sets of springs 10 are fixedly installed on the bottom inner wall of the inner wall groove 7.

[0035] Inner wall groove 7: It is formed on the inner wall of the mounting platform 2 and slides and engages with the annular protrusion 8 on the side of the insertion locking platform 3, providing a track for the movement of the insertion locking platform 3. At the same time, the bottom inner wall is fixed with spring 10, which supports and resets the insertion locking platform 3.

[0036] Spring 10: There are multiple sets, fixed to the bottom inner wall of the inner wall groove 7, with one end connected to the annular protrusion 8. Under normal conditions, it keeps the plug-in locking platform 3 separated from the contact switch 11; when the screwdriver is pressed, the spring 10 is compressed, and the plug-in locking platform 3 moves down to contact the contact switch 11.

[0037] Insertion locking platform 3: Installed inside the mounting platform 2, its side has an integrally formed annular protrusion 8 corresponding to the inner wall groove 7. The annular protrusion 8 slides and engages with the inner wall groove 7, and is fixedly connected to the spring 10.

[0046] Slider 15: integrally formed on both sides of the locking block 14 at the position corresponding to the inner wall groove 13, slidingly engaging with the inner wall groove 13, so that the locking block 14 can move stably within the rectangular groove 12 and transmit the elastic force of the second spring 16.

[0047] Spring 2 16: Fixed inside the inner wall groove 13, one end is connected to the slider 15, providing elastic force to the locking block 14, so that when it is not squeezed by the threaded ring 4, the lower end does not engage with the triangular notch 18 on the plug rod body 6; when squeezed, it contracts, so that the lower end of the locking block 14 engages with the triangular notch 18.

[0048] Rectangular groove 12: It is formed on the mounting platform 2, at least one of which is connected to the interior of the mounting platform 2, and is used to install components such as the locking block 14 in the locking structure.

[0049] Inner wall groove 13: It is formed on the inner wall of the rectangular groove 12, and a spring 16 is fixedly installed inside. It slides and engages with the sliders 15 integrally formed on both sides of the locking block 14, providing a track for the movement of the locking block 14 and applying elastic force through the spring 16.

[0050] Threaded ring 4: Used to adjust and fix the telescopic length of the plug-in rod 6. It has an inclined pressing surface 17 on one side of the pressing locking block 14. By rotating the threaded ring 4, it can be moved closer to or away from the locking block 14, thereby squeezing and releasing the locking block 14 to fix or release the plug-in rod 6.

[0051] Inclined pressing surface 17: It is set on one side of the threaded ring 4 for pressing the locking block 14. When the threaded ring 4 is rotated close to the locking block 14, the inclined pressing surface 17 fits against the arc transition surface of the locking block 14, squeezing the locking block 14 to lock the plug rod body 6; when the threaded ring 4 is rotated away from the locking block 14, the squeezing of the locking block 14 is released.

[0052] Working principle: When using this device, when aligning the end of the plug rod 6 with the screw and squeezing it, the plug rod 6 will press against the plug locking platform 3. The plug locking platform 3 will then contact the contact switch, at which point the lighting lamp 5 will turn on to illuminate the end of the plug rod 6 and provide a light source.
