For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] like Figures 1-8The auxiliary handle lever mounting structure of a dual power supply switch shown includes a housing 1, a handle 2, a rotating shaft, and an auxiliary handle lever 3. The upper end of the housing 1 has a strip-shaped opening 4, and its corner ends are provided with storage seats 7. The handle 2 is disposed inside the housing 1 and located below the opening 4. The upper end of the handle 2 has a slot 5, and its lower part has a connecting groove 6. The rotating shaft is disposed inside the housing 1 and connected to the connecting groove 6, and is linked with the handle 2. The auxiliary handle lever 3 is detachably connected to the handle 2. When in use, the lower part of the auxiliary handle lever 3 can extend into the housing 1 along the opening 4 and connect to the slot 5. When stored, the auxiliary handle lever 3 can be stored in the storage seat 7.

[0038] In the above technical solution, the integrated design of the housing, handle, pivot and detachable auxiliary handle lever achieves a compact overall structure, which is easy to assemble and maintain; the auxiliary handle lever can be inserted into the slot along the opening of the housing to form a lever fulcrum, which significantly reduces the operating force required for manual switching and saves more effort; the auxiliary handle lever can be detached and fixed in the storage base, which is easy to store, does not affect the packaging, can avoid loss or damage, and improves the reliability of the equipment.

[0039] Furthermore, the auxiliary handle lever 3 is T-shaped, including a plug 8 and a T-shaped plastic sleeve 9 fitted onto the upper end of the plug 8. The plug 8 and the T-shaped plastic sleeve 9 are injection molded. When in use, the plug 8 is inserted into the slot 5, and the T-shaped plastic sleeve 9 is positioned above the opening 4. In this technical solution, the T-shaped plastic sleeve is injection molded, making it more comfortable to hold and improving the operating feel; the integrated injection molding design of the plug 8 and the plastic sleeve enhances the connection strength and prevents loosening during use.

[0040] Furthermore, the lower edge of the insertion rod 8 is circumferentially formed with a first arc surface 10, and the upper edge of the slot 5 is circumferentially formed with a second arc surface 11 that mates with the first arc surface 10. In this technical solution, the first arc surface of the insertion rod mates with the second arc surface of the slot, which serves as a guide and makes assembly more convenient; the arc surface contact reduces insertion and removal friction and extends the service life of the insertion rod and the slot.

[0041] Furthermore, the handle 2 includes a connecting seat 12 and a mounting seat 13 formed below the connecting seat 12. The slot 5 is formed longitudinally on the connecting seat 12, and the connecting groove 6 is formed laterally on the mounting seat 13. The surface of the connecting seat 12 is provided with multiple reinforcing ribs 14 extending to the surface of the mounting seat 13. In this technical solution, the handle surface is provided with multiple reinforcing ribs to improve bending resistance and prevent deformation under high loads. The connecting seat and the mounting seat are designed vertically, with the upper end connected to the lever and the lower end connected to the rotating shaft. By utilizing the lever principle, the force transmission path is optimized to ensure the linkage efficiency of the rotating shaft.

[0042] Furthermore, the connecting groove 6 is square, and the rotating shaft is a matching square shaft. In this technical solution, the square connecting groove and the square shaft cooperate to eliminate gaps during rotation and improve the linkage accuracy between the handle and the rotating shaft; the compatibility between the square shaft and the square groove simplifies the assembly steps and reduces the assembly difficulty.

[0043] Furthermore, the T-shaped plastic sleeve 9 includes an integrally formed horizontal block 15 and a vertical block 16, with multiple material-stealing holes 17 on both sides of the lower end of the horizontal block 15. In this technical solution, the material-stealing hole design on both sides of the horizontal block of the T-shaped plastic sleeve reduces material usage and lowers the overall weight; at the same time, it ensures the load-bearing capacity of the plastic sleeve, making it more reliable to hold.

[0044] Furthermore, the upper end of the storage seat 7 forms a step with a mounting seat 18 of the housing 1, and the upper end of the storage seat 7 is lower than the upper end of the mounting seat 18; the upper end of the storage seat 7 is provided with a storage opening 19, and the interior of the storage seat 7 forms an accommodating space; a baffle 20 is constructed upward on the outer side of the upper end of the storage seat 7, and the inner wall of the baffle 20 and the outer wall of the mounting seat 18 are provided with opposing retaining strips 21; the insert 8 of the auxiliary handle lever 3 and the vertical block 16 extend into the accommodating space along the storage opening 19; the two sides of the horizontal block 15 abut against the two retaining strips 21, and the upper end surface of the horizontal block 15 is lower than the upper end surface of the retaining strip 21. In this technical solution, the horizontal block is inserted between the card strips, and the insert rod is embedded into the receiving space to achieve one-click storage. The card strip and the baffle form a limiting space to prevent the auxiliary handle lever from shaking or falling off during storage. The stepped storage base design makes full use of the shell structure, so that the upper part of the lever is lower when stored, without affecting the packaging.

[0045] Furthermore, the vertical block 16 has first guide slopes 22 on both sides, and the edge of the storage opening 19 has a second guide slope 23 that cooperates with the first guide slopes 22. In this technical solution, the first guide slope and the second guide slope cooperate to guide the auxiliary handle lever to be accurately inserted into the storage opening.

[0046] Furthermore, protruding walls 24 are formed on both sides of the vertical block 16 above the first guide slope 22. The vertical block 16 extends into the receiving space, and the upper end of the protruding wall 24 abuts against the lower edge of the receiving opening 19. The upper end of the protruding wall 24 transitions to the side wall of the vertical block 16 with an arc. In this technical solution, the abutment between the protruding wall and the lower edge of the receiving opening prevents the auxiliary handle lever from coming out after it is retracted to a certain extent. The arc transition of the protruding wall makes it easier for the auxiliary handle lever to be pulled out under force.

[0047] Furthermore, a positioning ring 25 is formed on the bottom surface of the housing 1 within the accommodating space, and a positioning groove 26 is formed within the positioning ring 25 to fit the end of the insertion rod 8. In this technical solution, the formation of the positioning groove on the positioning ring ensures that the end of the insertion rod is fixed when the auxiliary handle lever is stored, preventing displacement; after the end of the insertion rod is embedded in the positioning groove, a double limiting (locking strip + positioning groove) is formed, further enhancing the storage stability.

[0048] In this specific embodiment, addressing the issues of space-consuming, labor-intensive, and inconveniently stored auxiliary switching devices in existing dual-power transfer switches, the above solution utilizes an auxiliary handle lever in conjunction with the handle. The auxiliary handle lever can be inserted into a slot on the handle along the opening of the housing. The bottom of the auxiliary handle lever forms a lever fulcrum within the slot, amplifying the force through the lever principle and significantly reducing the force required for manual switching. The auxiliary handle lever is detachable and fixed to the housing storage base for convenient storage, without affecting packaging and preventing loss or damage. The above structure is more labor-saving, compact, and easy to store.
