Referring to fig. 1, fig. 1 is a schematic structural diagram of a multifunctional speeder wrench according to an embodiment of the utility model. To achieve at least one of the advantages and other advantages, an embodiment of the present utility model provides a multi-functional quick wrench. As shown in the figures, the multi-function quick wrench includes a handle 12, a ratchet head 14, a double tooth pawl 16, a driver adapter sleeve 18, and a square adapter 20.

The ratchet head 14 is clamped to one end of the handle 12, which is rotatable about its own axis, e.g., clockwise or counterclockwise, and the ratchet head 14 has opposite first and second ends, which may be understood to be the leading and trailing ends of the ratchet head 14, respectively.

The double-tooth pawl 16 is movably disposed within the handle 12, and the double-tooth pawl 16 is capable of engaging the ratchet head 14 within the range of motion of the double-tooth pawl 16. When the double-tooth pawl 16 is shifted to the left of the handle 12, the ratchet head 14 can only rotate in a clockwise direction; conversely, when the double-tooth pawl 16 is shifted to the right side of the handle 12, the ratchet head 14 can only rotate in the counterclockwise direction; in addition, when the dual-tooth pawl 16 is fully disposed within the handle 12 (it will be appreciated that the dual-tooth pawl 16 is in an intermediate state), the ratchet head 14 is capable of rotating in either direction.

The driver joint sleeve 18 is connected to the first end of the ratchet head 14, and the driver joint sleeve 18 follows the ratchet head 14 to rotate synchronously, i.e. the driver joint sleeve 18 rotates synchronously when the ratchet head 14 is rotated. The screwdriver bit adapter sleeve 18 is used to connect to a screwdriver bit 26 that can be used with a variety of screwdriver bits 26 that are needed to facilitate a worker's work (2 types of screwdriver bits 26 are provided as shown). Preferably, the socket of the screwdriver bit joint sleeve 18 is a hexagonal hole, so that the screwdriver bit 26 connected with various specification types can be replaced conveniently, and workers can work conveniently.

The square joint 20 is connected with the second end of the ratchet head 14, and the square joint 20 synchronously rotates along with the ratchet head 14. That is, when the ratchet head 14 is rotated, the square joint 20 is also rotated synchronously. The square joint 20 is used for connecting nut sleeves 24, and can be connected with various nut sleeves 24 with required specifications so as to facilitate the nut disassembly and assembly operation of workers. In some embodiments, the square connector 20 is an outer square connector, which may be 6.35mm in gauge, which may be equivalent to the socket gauge of the driver connector sleeve 18.

The surface of the square connector 20 is provided with a limit ball 22. The limiting ball 22 protrudes from the surface of the square connector 20 under the action of no external force, and is pressed into the square connector 20 when being pressed by the external force. For example, in the process of sleeving the nut sleeve 24 on the square joint 20, the nut sleeve 24 presses the limiting ball 22 into the square joint 20, and then after the nut sleeve 24 is completely sleeved on the square joint 20, the limiting ball 22 resets and clamps the main nut sleeve 24, so as to prevent the nut sleeve 24 from falling off. Subsequently, when the nut sleeve 24 is to be detached, the nut sleeve 24 is pulled out by external force.

In some embodiments, the hook tooth portion of the dual tooth pawl 16 engages with the ratchet portion of the ratchet head 14. The ratchet portion of ratchet head 14 may be convex to facilitate engagement.

In some embodiments, the dual-tooth pawl 16 is hinged within the handle 12 to facilitate the pulling of the dual-tooth pawl 16. The dual tooth pawl 16 may be bearing coupled to the handle 12. In some embodiments, the ratchet head 14 is made of metal to improve the overall structural strength.

In summary, according to the multifunctional speeder wrench provided by the embodiment of the utility model, through the matching arrangement of the ratchet head 14, the double-tooth pawl 16, the screwdriver joint sleeve 18 and the square joint 20, the multifunctional speeder wrench can simultaneously meet the replacement and use of various types of screwdriver heads 26 and nut sleeves 24, and reduce the workload of operators.

In addition, it should be understood by those skilled in the art that although many problems exist in the prior art, each embodiment or technical solution of the present utility model may be modified in only one or several respects, without having to solve all technical problems listed in the prior art or the background art at the same time. Those skilled in the art will understand that nothing in one claim should be taken as a limitation on that claim.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
