[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 A wall sander for decorative engineering includes a sander body 1. A main handle 2 is horizontally fixedly installed on the upper end of the sander body 1, and a power cord 21 is electrically connected to the rear end of the main handle 2. A vertical mounting plate is installed on the side of the sander body 1, and an auxiliary handle 3 is fixedly connected to the surface of the vertical mounting plate. The auxiliary handle 3 is located below the main handle 2. The surface of the auxiliary handle 3 is provided with a cord winding mechanism, and the interior of the auxiliary handle 3 is provided with a quick-release groove and an extension rod 4 detachably connected to the quick-release groove. In actual use, this wall sander for decorative engineering, with its designed main handle 2 and auxiliary handle 3, provides workers with a more stable and efficient operating experience. The dual-handle structure not only effectively alleviates the fatigue caused by long-term single-handed operation, but also significantly improves the accuracy and efficiency of sanding, ensuring that every wall surface achieves the ideal sanding effect. In addition, the auxiliary handle... The cleverly designed cable groove 31 on the surface of the handle 3 provides convenient storage space for the power cord 21, preventing the power cord 21 from becoming tangled during storage or transportation of the main body of the grinder 1. This not only keeps the equipment clean and aesthetically pleasing but also extends the service life of the power cord 21, saving valuable time for the next use. More importantly, the threaded groove 32 inside the auxiliary handle 3 and the extension rod 4 are designed with a detachable connection, allowing the equipment to easily adapt to the needs of grinding walls at different heights. Whether working at low or high places, the mode can be quickly switched with a simple operation, greatly expanding the functionality and applicability of the equipment. This modular and multifunctional design not only reflects a deep understanding of user needs but also provides workers with a more flexible and convenient operating experience, truly achieving a perfect combination of equipment performance and practicality.

[0029] Furthermore, the auxiliary handle 3 is fixedly installed on the side of the main body 1 of the sander via a mounting plate. In actual operation, when the worker feels fatigued due to prolonged single-handed operation, they can easily switch to two-handed operation mode by holding the auxiliary handle 3 with the other hand. This dual-handle design not only provides the worker with a more balanced force point, but also significantly improves the stability and control precision during the sanding process, ensuring that every wall surface can achieve the ideal sanding effect. Through the coordinated operation of both hands, the worker can better distribute the force, effectively alleviate fatigue, and thus maintain a high-efficiency working state, avoiding a decrease in sanding quality or efficiency due to fatigue.

[0030] Furthermore, the cord winding mechanism is a winding groove 31 formed on the surface of the auxiliary handle 3. During use, after the grinding operation is completed, in order to ensure that the power cord 21 is neat and orderly and avoids tangling, the worker can cleverly store it in the carefully designed winding groove 31 on the surface of the auxiliary handle 3. This user-friendly storage design not only effectively solves the problem that the power cord 21 is easy to get tangled during the storage or transportation of the grinding machine body 1, but also greatly simplifies the preparation work before the next use. By neatly winding the power cord 21 in the winding groove 31, the worker can quickly organize the equipment, save valuable time, and extend the service life of the power cord 21, ensuring that each operation can start in the best condition.

[0031] Furthermore, the power cord 21 can be wound in the winding groove 31. When in use, the winding groove 31 on the surface of the auxiliary handle 3 can improve the stability of the auxiliary handle 3 and store the power cord 21, thus increasing its functionality.

[0032] Furthermore, the quick-release groove is a threaded groove 32 inside the auxiliary handle 3. When in use, the auxiliary handle 3 can also function as a quick-release connection extension rod 4 through the threaded groove 32, which further enriches the function of the auxiliary handle 3, making the auxiliary handle 3 a three-in-one device and giving full play to its practicality.

[0033] Furthermore, a threaded rod 41 is fixedly connected to the top of the extension rod 4. In use, the extension rod 4 is threaded into the inside of the threaded groove 32 through the threaded rod 41, and can be fixedly connected to the auxiliary handle 3.

[0034] Furthermore, the threaded rod 41 is inserted into the threaded groove 32 and threadedly connected to the threaded groove 32. When the main body of the grinder 1 needs to grind the wall surface at a high position, the threaded rod 41 at the front end of the extension rod 4 can be aligned with the inside of the threaded groove 32 and threadedly inserted, thereby switching the main body of the grinder 1 to the extended form. At this time, the worker can hold the extension rod 4 and control the main body of the grinder 1 to grind the wall surface at a high position.

[0035] Furthermore, the extension rod 4 is detachably connected to the auxiliary handle 3 via the threaded rod 41 and the threaded groove 32. When the extended form is not needed, the extension rod 4 can be rotated to disengage from the threaded groove 32, thus restoring the lightweight and flexible form, thereby improving the overall applicability.

[0036] Working Principle: This utility model discloses a wall sander for decorative engineering. When workers experience fatigue from prolonged single-handed operation, they can use the auxiliary handle 3 to operate with both hands, significantly improving sanding stability and work efficiency, ensuring high-quality completion of tasks. After use, the power cord 21 can be easily wound into the winding groove 31 on the surface of the auxiliary handle 3, avoiding tangling and facilitating storage and future use, thus improving operational convenience. When sanding high walls, simply align the threaded rod 41 at the front end of the extension rod 4 with the threaded groove 32 inside the auxiliary handle 3 and insert it into the thread to quickly switch to the extended mode. Workers can then easily control the main body 1 of the sander to complete high-altitude operations by holding the extension rod 4. Furthermore, when the extended function is not needed, simply rotating the extension rod 4 to disengage it from the threaded groove 32 will restore the device to its lightweight and flexible conventional form, meeting the needs of different scenarios and thus improving overall applicability.
