Removing recalled bolts requires dozens of operations, taking nearly thirty minutes per machine, greatly impacting repair efficiency and increasing labor and time costs. Therefore, an adjustable composite handle manual tool is proposed to address these problems. Utility Model Content

[0006] The working component includes a connecting plate, a metal tray fixedly connected to one side of the connecting plate, a rotating shaft rotatably connected inside the metal tray, a metal gear fixedly connected to the top of the rotating shaft, and a hexagonal gear fixedly connected to the side of the rotating shaft away from the metal gear.
[0007] Preferably, the outer shell is made of ABS and integrally formed by 3D printing technology, and the connecting plate is fixedly connected to one side of the outer shell.
[0008] Preferably, the metal tray is located on the side of the connecting plate away from the outer shell, and the metal tray extends through both the upper and lower sides of the rotating shaft.

[0021] 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.
[0022] This utility model provides the following technical solution:
[0023] Example 1
[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4An adjustable composite handle hand tool includes a housing 1, on which a working component 2 is disposed;
[0025] The working component 2 includes a connecting plate 201, a metal tray 202 fixedly connected to one side of the connecting plate 201, a rotating shaft 203 rotatably connected inside the metal tray 202, a metal gear 204 fixedly connected to the top of the rotating shaft 203, and a hexagon 205 fixedly connected to the side of the rotating shaft 203 away from the metal gear 204.
[0026] The outer shell 1 is made of ABS and is integrally molded using 3D printing technology. The connecting plate 201 is fixedly connected to one side of the outer shell 1.
[0027] The outer shell 1 is made of ABS material and is integrally molded using 3D printing technology. ABS material has high strength, high toughness and good processing performance, which can ensure the durability and impact resistance of the outer shell 1. 3D printing technology enables the outer shell 1 to be manufactured quickly and accurately, and the integral molding design reduces assembly steps and potential connection problems, improving the stability and reliability of the overall structure. The connecting plate 201 is fixedly connected to one side of the outer shell 1, providing a stable mounting base for the working component 2 and ensuring that the working component 2 can work stably.
[0028] The metal tray 202 is located on the side of the connecting plate 201 away from the outer shell 1, and the upper and lower sides of the rotating shaft 203 both pass through the metal tray 202.
[0029] The metal tray 202 is located on the side of the connecting plate 201 away from the outer shell 1, and the upper and lower sides of the rotating shaft 203 both pass through the metal tray 202. This structure allows the rotating shaft 203 to rotate stably within the metal tray 202, thereby ensuring the stable installation and operation of the metal gear 204 and the hexagon 205, improving the accuracy and reliability of the working component 2, and making the tool more stable and accurate during use.
[0030] The hexagonal 205 has a hexagonal prism design and is compatible with the opening on the nut of a standard bolt.
[0031] The hexagonal 205 has a hexagonal prism design and is compatible with the opening on the nut of a standard bolt. This design allows the hexagonal 205 to fit tightly into the opening of the bolt nut, preventing slippage when disassembling or installing bolts. This improves the efficiency and safety of using hand tools and reduces operational errors or tool damage that may be caused by slippage.
[0032] By using the above technical solution, the outer casing 1 is inserted into the narrow space of the car, and the hexagonal 205 on the metal tray 202 is inserted into the nut. By rotating the handle 301, the connecting rod 302 rotates along with it. The driving teeth on the connecting rod 302 drive the driven teeth on the metal gear 204 that meshes with it, causing the metal gear 204 to rotate. Under the transmission of the rotating shaft 203, the hexagonal 205 inserted into the nut is driven to rotate, and the bolt is disassembled. This achieves the advantage of operating without changing the original maintenance space layout.
[0033] Example 2
[0034] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the following is obtained: a driving component 3 is provided on the outer shell 1;
[0035] The drive assembly 3 includes a hand handle 301, and a connecting rod 302 is fixedly connected to one side of the hand handle 301.
[0036] The drive assembly 3 includes a hand handle 301, on one side of which a connecting rod 302 is fixedly connected. This design allows the user to easily apply force by holding the hand handle 301, and then transmit the force to the working assembly 2 through the connecting rod 302 to realize the operation of the manual tool.
[0037] The connecting rod 302 moves through the outer shell 1 on the side away from the handle 301, and a drive tooth is provided on the side of the connecting rod 302 away from the handle 301.
[0038] The connecting rod 302 extends through the housing 1 on the side away from the handle 301 and is equipped with a drive tooth. This design allows the connecting rod 302 to move flexibly within the housing 1. At the same time, the drive tooth cooperates with the metal gear 204 in the working component 2 to achieve effective power transmission. This structure ensures the accuracy and efficiency of power transmission, enabling the hand tool to work smoothly.
[0039] The metal gear 204 is provided with a driven tooth, which meshes with the driving tooth.
[0040] The metal gear 204 is provided with driven teeth, which mesh with the driving teeth. This design ensures that power can be accurately transmitted from the driving component 3 to the working component 2, realizing the effective conversion and utilization of power.
[0041] Through the above technical solution, the hand handle 301 and the connecting rod 302 act as the driving part of the entire tool. By rotating the hand handle 301, the connecting rod 302 is driven to rotate. The driving teeth on the connecting rod 302 drive the driven teeth on the metal gear 204 to rotate, thereby realizing the rotation of the hexagon 205.
[0042] In actual operation, when using this device, the user first uses the original 07AAA tool to slightly loosen or tighten the threads on the bolt. Then, the outer shell 1 of the adjustable compound handle manual tool is inserted into the confined space of the car to be operated, allowing the hexagonal 205 on the metal tray 202 on the side of the connecting plate 201 away from the outer shell 1 to accurately engage with the nut hole of the target bolt. The hexagonal prism design of the hexagonal 205 is adapted to the standard bolt nut hole, ensuring a tight engagement and preventing slippage. Hold the outer casing 1 with one hand and rotate the handle 301 with the other hand. The rotation of the handle 301 causes the connecting rod 302, which is fixedly connected to it, to rotate together. The driving teeth on the connecting rod 302 drive the driven teeth to rotate, which in turn causes the metal gear 204 to rotate. The rotation of the metal gear 204 is transmitted to the hexagon 205 through the rotating shaft 203, which is fixedly connected to it. Since the hexagon 205 is already inserted into the bolt and nut, the rotation of the hexagon 205 will drive the bolt and nut to rotate together, thereby realizing the disassembly or installation of the bolt in a narrow space.
[0043] 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 may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
