Description

Technical Field

[0001] This utility model relates to the field of hardware tool technology, specifically a durable four-jaw swivel ratchet screwdriver. Background Technology

[0002] The four-jaw swivel ratchet screwdriver is a powerful and practical tool with many significant functions. It uses a high-strength chrome vanadium steel four-jaw swivel that can firmly clamp the screwdriver head from multiple directions. Even with large torque, the screwdriver head is not easily loosened or dislodged, ensuring stable and continuous operation. It is ideal for high-precision work such as electronic product repair and precision instrument assembly. The ratchet mechanism is ingeniously designed; no repeated insertion and removal are required during operation. Simply turning the handle back and forth achieves continuous tightening or loosening. When dealing with a large number of screws, it saves a lot of time and effort. It is also very suitable for automotive repair and maintenance. Moreover, by adjusting the mechanism to switch the ratchet direction, it can operate flexibly in complex environments such as narrow spaces and high-altitude operations.

[0003] However, traditional screwdrivers often have exposed tips when not in use. If they are accidentally dropped, they may cause serious damage to the installed tips, such as bending or deformation. Furthermore, exposed tips may rust in humid environments, which seriously affects subsequent use and user experience, thus severely impacting their lifespan and durability. To address this, we have proposed a durable four-jaw swivel ratchet screwdriver. Utility Model Content

[0047] External thread 17: On the outer side of the shaft end of the detachable kit 3 opposite to the internal thread 16, it mates with the internal thread 19 of the cutter head holder 4 and is used to connect the detachable kit 3 and the cutter head holder 4.

[0048] Anti-slip strip 218: A group of strips are distributed in a ring at equal intervals on the outside of the removable kit 3, which provides better friction when disassembling and installing the removable kit 3, making it easier to operate;

[0049] Internal thread 19: Inside the shaft end of the cutter head placement 4 on the side corresponding to the detachable kit 3, it mates with external thread 17 of the detachable kit 3 to connect the cutter head placement 4 and the detachable kit 3;

[0050] Cutter head storage compartment 20: A group of cutter heads are arranged in a ring inside the cutter head storage component 4 to store spare cutter heads 5, which are convenient to use at any time and meet different work needs;

[0051] Cutter head protection chamber 21: Located in the center of the inside of the cutter head holder 4, it is used to hold the cutter head 6 and prevent the cutter head 6 from oxidizing, rusting or being damaged due to falling when idle.

[0052] Working principle: Install the durable four-jaw swivel ratchet screwdriver correctly according to the diagram. The inner cavity 12 of the handle sleeve 1 engages with the solid rod 8 of the screwdriver body 2. The four sliding grooves 13 within the inner cavity 12 slide with the four sliding strips 9 on the outer side of the solid rod 8, allowing the handle sleeve 1 to be stably fitted onto the screwdriver body 2. Simultaneously, the fixing hole 14 on the outer side of the handle sleeve 1 connects to the threaded hole 10 on the solid rod 8 via an adapter screw, further preventing the handle sleeve 1 from slipping. When the screwdriver is needed, unscrew the head guard device from the screwdriver body 2. The detachable component 3 within the head guard device is a hollow cylinder. Its internal thread 16 engages with the external thread 11 on the side of the four-jaw swivel ratchet structure 7 on the screwdriver body 2 opposite to the head 6. After unscrewing the detachable component 3, the four-jaw swivel ratchet structure 7 is exposed. The high-strength chromium vanadium steel four-jaw swivel firmly holds the cutter head 6. During operation, rotating the handle sleeve 1 transmits the rotational force of the handle sleeve 1 to the ratchet structure 7 of the four-jaw swivel through the screwdriver body 2. The ratchet mechanism consists of a ratchet, pawl, and spring. Under the action of the spring, the pawl engages with the ratchet teeth to achieve unidirectional or bidirectional rotational movement, thereby driving the cutter head 6 to tighten or loosen the screw. Users can switch the ratchet direction by adjusting the mechanism to adapt to different operating needs. If the cutter head 6 needs to be replaced, the detachable kit 3 can be unscrewed from the cutter head holder 4. The spare cutter head 5 can be taken out from the cutter head holder compartment 20 inside the cutter head holder 4 and installed on the four-jaw swivel ratchet structure 7. The cutter head protection compartment 21 in the center of the cutter head holder 4 can hold the cutter head 6 when not in use, which protects the cutter head from oxidation, rust, and damage from falling, thus improving overall durability.

[0053] 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 can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
