AI Technical Summary

Technical Problem

Existing folding hex wrenches require frequent hand adjustments during use, resulting in cumbersome operation and low efficiency, especially in confined spaces or continuous work scenarios.

Method used

By combining a ratchet mechanism with a folding Allen wrench, unidirectional rotational transmission is achieved through the ratchet mechanism. The Allen wrench head drives the tool to work when rotating in the forward direction and idles when rotating in the reverse direction, thus avoiding the need for hand position adjustment.

Benefits of technology

It enables continuous operation without frequent hand adjustments, improving work efficiency and making it particularly suitable for confined spaces or continuous work scenarios, saving time and effort.

Claims

1. A folding socket wrench comprising a sheath and a plurality of socket heads, a peripheral wall of the sheath being provided with at least one U-shaped recess for accommodating a socket head, an opening of the recess being provided with a pin, one end of the socket head being bent around the pin so as to be hinged to the sheath; characterized in that: A ratchet mechanism is installed at one end of the sheath away from the groove along its length. The ratchet mechanism is provided with a gripping handle for operating the ratchet mechanism and a reversing lever for controlling the engagement direction of the pawl and the ratchet. ​ 2. The folding hex key according to claim 1, wherein: The sheath is cylindrical in shape, and there are two grooves, which are arranged on opposite sides of the sheath. The bottom of each of the two grooves is provided with a step that corresponds to a hexagonal socket wrench. When the hexagonal socket wrench is extended to the length direction of the sheath, the step abuts against the corresponding hexagonal socket wrench.

3. The folding hex key according to claim 2, wherein: The steps at the bottom of the two grooves are set in opposite directions.

4. The folding hex key according to any one of claims 1 to 3, wherein: Each groove contains a spacer between adjacent hexagonal socket heads, and the spacer is fitted onto the pin.
