[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Example

[0022] Please see Figure 1-5 This utility model provides a technical solution: a combined stacking hex wrench, including a handle 1, an outer wrench 2 at one end of the handle 1, a retaining assembly for stacking wrenches inside the outer wrench 2, the retaining assembly including multiple inner wrenches 3 arranged sequentially inside the outer wrench 2, each inner wrench 3 having a mating plate 301 on its outer wall, and both the outer wrench 2 and the multiple inner wrench 3 having a sliding groove 4 inside, the inner wall of the sliding groove 4 having a magnetic plate 5, and the other end of the handle 1 having multiple positioning grooves 6. The outer wrench 2 and the multiple inner wrenches 3 are stacked and overlapped sequentially through the sliding groove 4, so that multiple wrenches of different sizes are overlapped as one unit. When overlapping, the magnetic plate 5 inside the sliding groove 4 is magnetically attracted to the mating plate 301 outside the inner wrench 3, thereby fixing the positions of the multiple wrenches of different sizes. When the wrench is extended for use, the inner wrenches extend synchronously, so that the extended wrench is in a solid state, ensuring the strength of the wrench.

[0023] The handle 1 is provided with an insert plate 7 on its outside. The insert plate 7 is provided with a protrusion 701 and a baffle 702 on its outside. When the wrench is needed, the insert plate 7 can be inserted into the positioning groove 6 corresponding to the wrench size as required, and extends into the sliding groove 4 of the wrench. The protrusion 701 on the outside of the insert plate 7 is positioned between the magnetic plate 5 in the sliding groove 4 and the mating plate 301 on the outside of the inner wrench 3, thereby reducing the tightness of the magnetic plate 5 adsorbing the wrench at the corresponding position. Then, when the baffle 702 at the other end extends into the sliding groove 4, it abuts against the inner wrench, pushing the wrench out of the sliding groove 4 for use.

[0024] For an example, please refer to... Figure 1-5The outer wrench 2 is connected to one side of the handle 1 by bolts. Multiple inner wrenches 3 overlap and are located inside the outer wrench 2, and the multiple inner wrenches 3 are slidably connected to each other by sliding grooves 4. The mating plate 301 is connected to the outer wall of the inner wrench 3. The magnetic plate 5 is embedded and connected to the inner wall of the sliding groove 4 inside the outer wrench 2 and the inner wrench 3. When the inner wrenches 3 overlap, the outer mating plate 301 and the magnetic plate 5 are magnetically connected. Multiple positioning grooves 6 are located on the side of the handle 1 away from the wrench, and the multiple positioning grooves 6 correspond to the multiple sliding grooves 4 between the outer wrench 2 and the inner wrench 3. The positioning grooves 6 communicate with the interior of the sliding grooves 4. The protrusion 701 is located on the outer side of the insertion plate 7 near the positioning groove 6, and the protrusion 701 has an arc-shaped structure. The baffle 702 is located on the outer side of the other end of the insertion plate 7. The insertion plate 7 can be embedded in the positioning groove 6 and extend into the sliding groove 4 and slidably connected to the interior of the sliding groove 4. The protrusion 701 can lift and loosen the inner wrench 3 and the inner wall of the sliding groove 4. When in use, first insert the insert plate 7 into the positioning groove 6 of the corresponding size wrench according to the usage situation and extend it into the sliding groove 4 inside the wrench, abutting against the inner wrench 3 inside the sliding groove 4. The magnetic plate 5 inside the sliding groove 4 and the wrench are attracted and loosened by the protrusion 701 on the outside of the insert plate 7. With the help of the baffle 702 at the other end, the wrench in the sliding groove 4 is pushed out for use when it continues to go deeper.

[0025] The working process of this utility model is as follows: First, according to the usage requirements, the insert plate 7 is embedded into the positioning groove 6 of the corresponding size wrench and extends into the sliding groove 4 inside the wrench, abutting against the inner wrench 3 inside the sliding groove 4. The protrusion 701 on the outside of the insert plate 7 loosens the magnetic plate 5 inside the sliding groove 4 from the wrench, and with the help of the baffle 702 at the other end, the wrench in the sliding groove 4 is pushed out for use as it continues to extend. This utility model integrates multiple wrenches of different sizes into one unit, allowing for the extension of the appropriate size wrench as needed, enabling one wrench to be used with bolts of various sizes, thus improving the convenience of use and carrying.

[0026] 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.
