Technical Field

[0001] The utility model relates to the technical field of hand tools, in particular to a hexagonal wrench with an embedded rotating ring. Background Art

[0002] A wrench is a commonly used installation and disassembly tool, which is a hand tool that uses the lever principle to twist bolts, screws, nuts and other threaded fasteners or nuts with openings or socket holes for holding bolts or nuts. Common wrenches in life, such as hexagonal wrenches, when using an open-end hexagonal wrench to tighten a hexagonal nut or a hexagonal head bolt, the open-end hexagonal wrench needs to be re-fitted into the hexagonal nut or the hexagonal head bolt after rotating a certain angle, which increases the labor intensity and reduces the production efficiency. To solve this problem, electric socket wrenches and ratchet socket wrenches have been introduced on the market.

[0003] In actual use, since the side wall of the socket of the electric socket wrench and the ratchet socket wrench has no opening, when clamping a hexagonal nut, it is usually directly sleeved from the upper end of the nut.

[0012] As a preferred embodiment, a storage battery and a control terminal are sequentially installed on one side of the inner cavity bottom of the installation groove, the control terminal is located inside the storage battery and the micro motor, a switch button is installed on the top of the control terminal, the surface of the switch button movably penetrates the surface of the movable cover two, and a communication groove is formed in the side surface of one end of the lower housing, and the communication groove is correspondingly arranged on one side of the storage battery.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In this utility model, by pressing the unlocking button, the unlocking button moves downward to squeeze the return spring. When the unlocking button moves downward, the buckle end of the lock catch disengages from the engaging end inside the unlocking button, so that the lock catch disengages from the inside of the unlocking button.

At this time, the unlocking button is released, and the return spring resets to drive the unlocking button to move upward so that the engaging end of the unlocking button presses against the buckle end of the lock catch again, thus achieving the fitting and docking fixation of the opening and closing ends of the major arc and the minor arc of the rotating ring. Through this design, the minor arc of the rotating sleeve is allowed to open, facilitating the fitting of the wrench onto a hexagonal nut in a difficult-to-reach position or on a long screw. The design of the unlocking button makes the opening and closing of the rotating sleeve simple and fast, improving the convenience of use.

[0015] 2. In this utility model, when the major arc and the minor arc of the rotating ring sleeve the hexagonal nut, by pressing the switch button, after the control terminal receives the signal, the micro motor is started. When the micro motor operates, it drives the coupling and the transmission shaft to rotate while driving the first bevel gear to rotate. The first bevel gear synchronously drives the worm to rotate. The rotation of the worm drives the first worm gear and the second worm gear meshing with it to rotate, thereby driving the major arc and the minor arc of the rotating ring to rotate and rotate the hexagonal nut inside it. This method drives the rotating sleeve through the motor, reducing the physical strength required for manual rotation of the wrench and greatly reducing the labor intensity.

[0042] In one embodiment, a storage battery 8 and a control terminal 5 are sequentially installed on one side of the inner cavity bottom of the installation groove 103. The control terminal 5 is located inside the storage battery 8 and the micro-motor 401. A switch button 501 is installed on the top of the control terminal 5. The surface of the switch button 501 movably penetrates through the surface of the second movable cover 102.

When the switch button 501 is pressed, after the control terminal 5 receives the signal of the switch button 501, it controls the micro-motor 401 to operate. After the switch button 501 is released, when the control terminal 5 loses the signal, it controls the micro-motor 401 to stop. This structure is a common control structure in the prior art and will not be elaborated here; the storage battery 8 provides electrical energy for the device, and the communication groove 106 facilitates the connection of an external charging device to the storage battery 8 to store energy for the storage battery 8.

[0044] Working principle: In the initial state, the latch 6022 is located inside the unlocking button 6014, and the two are engaged with each other, so that one end of the major arc 601 of the rotating ring is fitted and butted with one end of the minor arc 602 of the rotating ring to form a circle. When using the hexagonal wrench with an embedded rotating ring to operate on some inaccessible positions or the hexagonal nuts on some long screws, since it is not convenient to put the hexagonal wrench on the hexagonal nut, at this time, the unlocking button 6014 can be pressed. The unlocking button 6014 moves downward to squeeze the return spring 6013. When the unlocking button 6014 moves downward, the buckle end of the latch 6022 disengages from the engaging end inside the unlocking button 6014, so that the latch 6022 disengages from the inside of the unlocking button 6014. At this time, the minor arc 602 of the rotating ring and the major arc 601 of the rotating ring can be opened and closed at the other end with the hinge end as the rotation axis. After the docking ends of the minor arc 602 and the major arc 601 of the rotating ring are opened, it can be directly sleeved from the side of the hexagonal nut. The minor arc 602 of the rotating ring is bypassed over the surface of the hexagonal nut and re-docked with one end of the major arc 601 of the rotating ring, and the latch 6022 is inserted back into the inside of the unlocking button 6014. At this time, the unlocking button 6014 is released, and the return spring 6013 is reset to drive the unlocking button 6014 to move upward so that the engaging end of the unlocking button 6014 presses against the buckle end of the latch 6022 again, so as to achieve the fitting and docking fixation of the opening and closing ends of the major arc 601 and the minor arc 602 of the rotating ring. Through this design, the minor arc of the rotating sleeve is allowed to open, which is convenient for putting the wrench on inaccessible positions or the hexagonal nuts on long screws. The design of the unlocking button makes the opening and closing of the rotating sleeve simple and fast, improving the convenience of use; when the major arc 601 and the minor arc 602 of the rotating ring are sleeved on the hexagonal nut, the switch button 501 can be pressed. After the control terminal 5 receives the signal, the micro motor 401 is started. While the micro motor 401 runs to drive the coupling 402 and the transmission shaft 403 to rotate, the bevel gear one 404 is driven to rotate. The bevel gear one 404 synchronously drives the worm 406 to rotate. The worm 406 rotates to drive the worm wheel one 6011 and the worm wheel two 6021 meshed with it to rotate, so as to drive the major arc 601 and the minor arc 602 of the rotating ring to rotate to rotate the hexagonal nut inside it. This method drives the rotating sleeve by the motor, reducing the physical strength required for manual rotation of the wrench and greatly reducing the labor intensity.

[0045] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
