Technical Field

[0001] This utility model relates to the field of screwdriver technology, specifically to a screwdriver for automotive repair with a lighting function. Background Technology

[0002] A screwdriver is a hand tool that uses a rotating handle to drive different shaped heads to tighten or loosen screws. It consists of a head, a shaft, and a handle, and comes in various types such as manual, ratchet, and electric. It is widely used in home repair, electronic equipment assembly, industrial manufacturing, and other scenarios. When using it, you need to select the corresponding shape of the screw head according to the screw size.

[0003] In automotive repair, to enable operation in dimly lit spaces such as the engine compartment and chassis, screwdrivers with integrated LED lights or other lighting devices on the handle or shaft are often used to clearly illuminate the screws and surrounding area. The heads are equipped with various replaceable high-strength metal bits, such as Phillips and hex, to accommodate all types of screws in automobiles.

[0004] However, existing designs that integrate lighting devices into the handle or shaft make later maintenance complicated. When the light malfunctions, the entire screwdriver needs to be disassembled or replaced, which increases maintenance costs and reduces the durability of the screwdriver. Therefore, a new type of automotive screwdriver with lighting function is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a screwdriver for automotive repair with a lighting function to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screwdriver for automotive repair with a lighting function, comprising a screwdriver, wherein the screwdriver consists of a cutting head and a handle;

[0007] The handle has a detachable lamp holder at the top and a magnetic block fixedly installed at the bottom of the lamp holder. The inner wall of the handle has a magnetic surface corresponding to the magnetic block for mounting the lamp holder. The outer wall of the handle has a rotating seat rotatably mounted on it, and a slider corresponding to the magnetic block is fixedly connected to the outer wall of the rotating seat. The slider has beveled edges to release the connection between the lamp holder and the handle.

[0008] By adopting the above technical solution, users can quickly install lighting fixtures by simply aligning the lamp holder with the inner wall of the handle and using magnetic attraction. When removing the lamp holder, users only need to rotate the rotating base to allow the slider's angled edge to insert between the magnetic block and the magnetic surface of the handle, thus forcing the magnetic block to separate from the magnetic surface of the handle, achieving a quick removal effect. This installation and removal process is simple, easy and convenient to use, and can achieve quick installation and removal without the need for tools. In later maintenance and replacement, the lighting fixture can be operated independently, improving the durability of the screwdriver and reducing replacement costs.

[0009] Furthermore, a slot is fixedly connected to the top of the handle, and the blade and the handle are detachably connected through the slot.

[0010] By adopting the above technical solution, the screwdriver can be flexibly fitted with different shaped bits according to the screw specifications through the slot at the top of the handle, thereby improving the versatility of the screwdriver and reducing the cost of use.

[0011] Furthermore, the grip has a built-in battery compartment, and a battery compartment cover is threaded to the bottom of the grip, with a lighting switch located at the bottom of the battery compartment cover.

[0012] By adopting the above technical solution, the screwdriver can meet the needs of mobile operation through the built-in battery compartment without the need for an external power source. By setting a lighting switch at the bottom of the battery compartment cover, users can adjust the lighting at any time when performing auto repair work, making it more convenient to use.

[0013] Furthermore, a lighting lamp is fixedly installed inside the lamp holder, and the lighting lamp has a ring-shaped design.

[0014] By adopting the above technical solution and designing a ring light, users can accurately illuminate the work area with uniform 360-degree lighting without blind spots in dim or narrow working environments, effectively avoiding shadows and significantly improving work efficiency.

[0015] Furthermore, a docking block is fixedly connected to the bottom of the lamp holder, and a conductive contact surface is fixedly installed on the bottom of the docking block.

[0016] By adopting the above technical solution, the position of the lamp holder can be more accurately positioned through the docking block, thereby ensuring the adsorption stability of the lamp holder and the grip.

[0017] Furthermore, multiple sets of metal spring pins corresponding to the conductive contact surface are fixedly installed on the inner wall of the grip. When the mating block is attached to the grip, the conductive contact surface and the metal spring pins make electrical contact to ensure the power supply of the lighting lamp.

[0018] By adopting the above technical solution, when the lamp holder and the handle are in an adsorbed state, the metal spring pin on the handle is subjected to pressure and makes tight elastic contact with the conductive contact surface on the mating block, thereby ensuring the power supply of the lighting lamp. This power supply method can adapt to the vibration generated by the screwdriver during use and improves the stability of the electrical contact.

[0019] Furthermore, multiple sets of magnetic blocks are fixedly connected to the bottom of the lamp holder, and the positions of the magnetic blocks and the slider are staggered.

[0020] By adopting the above technical solution, it is ensured that the slider and magnetic block will not interfere when the rotating seat is not rotating, thus further guaranteeing the adsorption stability between the lamp holder and the handle.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention, by incorporating a lamp holder and a rotating base, facilitates easy installation and removal. When installing a light fixture, users simply align the lamp holder with the inner wall of the handle for magnetic installation. Simultaneously, the metal spring pin on the handle, under pressure, creates a tight elastic contact with the conductive contact surface on the mating block, ensuring a stable power supply to the light fixture. This power supply method can withstand vibrations generated during screwdriver use, improving the stability of the electrical contact. To disassemble the lamp holder, users simply rotate the rotating base, causing the slider's angled section to insert between the magnetic block and the magnetic surface of the handle, forcing the magnetic block to separate from the handle's magnetic surface, thus achieving disassembly. This simple and convenient installation and removal process allows for quick and easy assembly and disassembly without the need for tools. For later maintenance and replacement, the light fixture can be operated independently, improving the screwdriver's durability and reducing replacement costs. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] A type of automotive screwdriver with a built-in light, such as Figure 1 - Figure 4 As shown, it includes a screwdriver 1.

[0031] Specifically, the screwdriver 1 consists of a blade 2 and a handle 5;

[0032] A lamp holder 31 is detachably connected to the top of the handle 5, and a magnetic block 311 is fixedly installed at the bottom of the lamp holder 31. The inner wall of the handle 5 has a magnetic surface corresponding to the magnetic block 311 for mounting the lamp holder 31. This allows users to quickly install the lamp 31 by simply aligning it with the inner wall of the handle 5 and using magnetic attraction. A rotating seat 4 is rotatably mounted on the outer wall of the handle 5, and a slider 41 corresponding to the magnetic block 311 is fixedly connected to the outer wall of the rotating seat 4. The slider 41 has beveled edges to release the lamp holder 31 from the handle. The connection between 5 allows the user to easily disassemble the lamp holder 31 by simply rotating the rotating base 4. This causes the angled slider 41 to insert between the angled magnetic block 311 and the magnetic surface of the handle 5, forcing the magnetic block 311 to separate from the magnetic surface of the handle 5. This achieves a quick disassembly. This assembly and disassembly process is simple, easy, and convenient, requiring no tools. In later maintenance and replacement, the lighting lamp 3 can be operated independently, improving the durability of the screwdriver 1 and reducing replacement costs.

[0033] Please see Figure 1 - Figure 4 The top of the handle 5 is fixedly connected to a slot 21, and the blade 2 and the handle 5 are detachably connected through the slot 21. Through the slot 21 at the top of the handle 5, the screwdriver 1 can flexibly change to different shaped blades 2 according to the specifications of the screw, thereby improving the versatility of the screwdriver 1 and reducing the cost of use.

[0034] Please see Figure 1 - Figure 4 The handle 5 has a built-in battery compartment, and the bottom of the handle 5 is threadedly connected to the battery compartment cover 51. The bottom of the battery compartment cover 51 is equipped with a lighting switch. The built-in battery compartment allows the screwdriver 1 to meet the needs of mobile operation without the need for an external power source. The lighting switch at the bottom of the battery compartment cover 51 allows the user to adjust the lighting 3 at any time when performing auto repair work, making it more convenient to use.

[0035] Please see Figure 1 - Figure 4 The lamp holder 31 is fixedly installed with a lighting lamp 3, which is a ring design. The ring lighting lamp 3 allows users to accurately illuminate the working area with uniform light from 360 degrees without dead angles in dim or narrow working environments, effectively avoiding shadows and significantly improving work efficiency.

[0036] Please see Figure 1 - Figure 4 The lamp holder 31 is fixedly connected to a docking block 312 at the bottom, and a conductive contact surface 313 is fixedly installed at the bottom of the docking block 312. The position of the lamp holder 31 can be more accurately positioned through the docking block 312, thereby ensuring the adsorption stability of the lamp holder 31 and the handle 5.

[0037] Please see Figure 1 - Figure 4 Multiple sets of metal spring pins 52 corresponding to the conductive contact surface 313 are fixedly installed on the inner wall of the handle 5. When the mating block 312 is attached to the handle 5, the conductive contact surface 313 and the metal spring pins 52 make electrical contact to ensure the power supply of the lighting lamp 3. When the lamp holder 31 and the handle 5 are in an adsorbed state, the metal spring pins 52 on the handle 5 are subjected to pressure and make tight elastic contact with the conductive contact surface 313 on the mating block 312, thereby ensuring the power supply of the lighting lamp 3. This power supply method can adapt to the vibration generated by the screwdriver 1 during use and improve the stability of the electrical contact.

[0038] Please see Figure 1 - Figure 4 Multiple sets of magnetic blocks 311 are fixedly connected to the bottom of the lamp holder 31, and the positions of the magnetic blocks 311 and the slider 41 are staggered to ensure that the slider 41 and the magnetic blocks 311 will not interfere when the rotating seat 4 is not rotating, thus further ensuring the adsorption stability between the lamp holder 31 and the handle 5.

[0039] The working principle of this utility model is as follows: When using screwdriver 1 for auto repair, the user needs to first select the corresponding shape of the screw head 2 according to the type of screw for installation. To remove the screw head 2, simply pull it out with force. To install the screw head 2, insert the cylindrical end of the screw head 2 into the slot 21.

[0040] When installing the lighting lamp 3, align the mating block 312 of the lamp holder 31 with the mounting part on the inner wall of the handle 5. After installation, slightly rotate the lamp holder 31 to ensure that the magnetic block 311 is firmly attracted to the magnetic surface of the handle 5. At this time, the metal spring pin 52 is subjected to the pressure of the mating block 312 and maintains elastic contact with the conductive contact surface 313 to achieve power supply to the lighting lamp 3.

[0041] Before using the screwdriver 1 for illumination, the battery compartment cover 51 needs to be opened by unscrewing along the threads, the battery is correctly placed into the battery compartment inside the handle 5, and then the battery compartment cover 51 is tightened. During use, the brightness of the light 3 is controlled by pressing the light switch at the bottom of the battery compartment cover 51.

[0042] When disassembling the lamp 3, the user only needs to rotate the rotating base 4 so that the angled surface of the slider 41 rotates synchronously along the angled surface of the magnetic block 311, entering between the magnetic block 311 and the magnetic surface of the handle 5 to form a barrier, forcing the magnetic block 311 and the handle 5 to release their adsorption. During this process, the conductive contact surface 313 and the metal spring pin 52 are forced to separate simultaneously, the metal spring pin 52 returns to its original state, and the power is disconnected. After completion, the user can directly remove the lamp holder 31 for maintenance or replacement.
