Description

Technical Field

[0001] This utility model relates to the field of screwdriver pressing sleeve technology, specifically a multifunctional screwdriver pressing sleeve. Background Technology

[0002] In various mechanical repair, assembly, and daily fastener handling scenarios, screwdrivers and their matching sleeves are commonly used tools. Their core function is to transmit power to complete the disassembly and installation of fasteners such as bolts and nuts. However, traditional screwdrivers and their matching sleeves have revealed many limitations in actual use, making it difficult to meet the increasingly diverse and high-intensity work requirements.

[0003] Traditional ratchet wrenches typically only have a single drive method, mostly an internal four-way drive structure. This structure has a clear upper limit to the torque it can generate when connected to a wrench for power transmission. While it might be able to manage some standard-sized fasteners, it falls far short when dealing with rusted, excessively tight, or large bolts and nuts. In practice, operators often have to apply more force to attempt to remove these fasteners, but due to the limited torque capacity of the internal four-way drive structure, this can easily damage connecting tools like ratchet wrenches, potentially causing stripping or breakage. This not only delays work progress but also increases tool replacement costs, failing to meet the needs of modern, complex work scenarios. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-4 As shown, the multi-functional screwdriver press sleeve includes a sleeve 1, and further includes: an internal hexagonal groove 4 and an internal square groove 5 for connecting to external tools, respectively opened at both ends of the sleeve 1. A hexagonal connecting rod 2 is inserted into the internal hexagonal groove 4; a non-rolling flat surface 3 is opened on the outer side of the sleeve 1; the internal hexagonal groove 4 and the internal square groove 5 are respectively opened at both ends of the sleeve 1. The hexagonal connecting rod 2 inserted into the internal hexagonal groove 4 can be connected to an external tool with a corresponding interface to realize the transmission of power, so that the sleeve 1 can rotate with the external tool. The internal hexagonal groove 4 can be connected to a square ratchet wrench. The internal hexagonal groove 4 is connected to the hexagonal socket wrench through the hexagonal connecting rod 2, which increases the torque and makes disassembly and processing easier.

[0021] It should be noted that the design of the internal hexagonal slot 4 and the internal square slot 5 allows the socket 1 to be used with tools of various different interfaces, eliminating the need to prepare multiple sockets of different specifications, reducing the number of tools and costs, and improving the versatility and efficiency of the tools.

[0022] The depths of the internal hexagonal slot 4 and the internal square slot 5 are each half the depth of the sleeve 1. Because the internal hexagonal slot 4 and the internal square slot 5 are set with two different shapes of slots and their depths are each half the depth of the sleeve 1, they can be adapted to tools with different interface types and meet the needs of various usage scenarios.

[0023] The sleeve 1 is circular on the outside, with six evenly spaced planes 3 surrounding it. Both the sleeve 1 and the hexagonal connecting rod 2 are made of metal. A through hole 6 is located in the center of the sleeve 1. Six anti-roll-off planes 3 are also located on the outer side of the sleeve 1. This design prevents the sleeve 1 from easily rolling when placed on a flat surface such as a workbench, avoiding potential damage or loss due to rolling, thus improving ease of use and safety. The through hole 6 in the center of the sleeve 1, without affecting its overall structural strength and functionality, may reduce weight, save materials, and facilitate observation of internal connections. The metal construction of both the sleeve 1 and the hexagonal connecting rod 2 ensures sufficient strength and hardness to withstand high torque and pressure, preventing damage and extending the tool's lifespan. Furthermore, the rational structural design, such as the internal through hole 6, may reduce the tool's weight to some extent while maintaining functionality, making it easier for operators to carry and use.

[0024] Working Principle: This multi-functional screwdriver press sleeve uses a socket 1 as its core component. Both ends of the socket 1 have internal hexagonal slots 4 and internal square slots 5, respectively. This double-slot design allows for connection to various external tools. The internal hexagonal slot 4 has a unique shape design, enabling direct connection to a square ratchet wrench. When the square ratchet wrench is inserted into the internal hexagonal slot 4, operating the ratchet wrench rotates the socket 1, achieving basic power transmission and meeting some routine disassembly or installation needs. A hexagonal connecting rod 2 is inserted inside the internal hexagonal slot 4, acting as a bridge. After connecting the hexagonal socket wrench to the hexagonal connecting rod 2, the hexagonal socket wrench, typically with a longer lever arm and a more rational structural design, can generate greater torque. When the hexagonal socket wrench is operated, power is transmitted sequentially through the hexagonal socket wrench and the hexagonal connecting rod 2 to the internal hexagonal slot 4, thereby rotating the socket 1. This connection method is particularly suitable for fasteners that require significant torque to disassemble or install, such as rusted bolts and nuts, making disassembly easier. An inner four-corner groove 5 is located at the other end of the sleeve 1, allowing it to connect to an external tool with an inner four-corner interface. When the corresponding tool is inserted into the inner four-corner groove 5, power can be transmitted by operating the tool, causing the sleeve 1 to rotate. This meets the requirements for tool connection and use in different scenarios. The sleeve 1 is circular on the outside, but six planes 3 are evenly distributed around its outer edge. When the sleeve 1 is placed on a flat surface such as a workbench, these six planes 3 contact the surface, increasing the friction and support stability between the sleeve 1 and the surface. Compared to a simple circular outer surface, this design significantly reduces the possibility of the sleeve 1 rolling, preventing tool damage or loss due to rolling, and improving ease of use and safety. The sleeve 1 has a through hole 6 located in the center. The through hole 6 serves multiple purposes while ensuring the overall structural strength and functionality of the sleeve 1 are not affected. On the one hand, it reduces the weight of socket 1, making it easier for operators to carry and use; on the other hand, it reduces the material required to manufacture socket 1, lowering production costs. Furthermore, the through hole 6 allows operators to easily observe the internal connections, such as checking whether the connection between the hexagonal connecting rod 2 and the internal hexagonal slot 4 is in place, helping to promptly identify and resolve potential problems. Both socket 1 and the hexagonal connecting rod 2 are made of metal. Metal materials have sufficient strength and hardness, making them less prone to deformation or damage when subjected to large torques and pressures. This allows the multi-functional screwdriver press sleeve to be used stably in various complex working environments, meeting different work intensity requirements, thereby extending the tool's service life. Under normal use, wrenches connected by the internal four-corner slot 5 cannot meet large torque requirements, causing damage to the ratchet wrench during use. An external hexagonal drive has been added to the original four-corner drive. A larger hexagonal socket can be selected to drive the drive end, fundamentally solving the problem of insufficient torque from the internal four-corner drive.It plays a crucial role in unconventional disassembly. Ordinary wrenches can only be driven by a square wrench like a ratchet wrench. This patented technology adds an external hexagonal drive, allowing the selection of a suitable adjustable wrench or open-end wrench, significantly improving its usability.
