[0029] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0030] Embodiment 1:

[0031] like Figure 1-Figure 4As shown, a multifunctional hand-held electric angle grinder of the utility model comprises an angle grinder body 1, a machine head 6 is installed at the front end of the angle grinder body 1, a protective cover 7 is installed on one side of the machine head, a handle 2 is fixed to one end of the protective cover 7, an opening 21 is opened at the end of the handle 2 close to the protective cover 7, the interior of the handle 2 is a dust suction bin 22, a cover plate 24 is installed at the end of the handle 2, and a miniature vacuum cleaner 23 is installed at the inner end of the handle 2 close to the cover plate 24. The interior of the handle 2 is designed as a dust suction bin 22 and a miniature vacuum cleaner 23, which realizes the integration of grinding and dust suction functions and simplifies the operation process. The protective cover 7 can effectively prevent flying dust and debris from causing harm to the operator, thereby improving the safety during use. Through the design of the opening 21 and the use of the miniature vacuum cleaner 23, the dust generated during the grinding process can be effectively absorbed, reducing environmental pollution and the impact on the operator's health. The cover plate 24 at the end of the handle 2 can be removed, allowing the user to quickly replace or maintain the internal dust suction component as needed.

[0032] See also Figure 1 and Figure 2 A drive shaft is connected to one side of the machine head 6. The drive shaft is used to install the blade 3. Blades 3 of different types and sizes can be easily replaced to meet different work requirements, such as grinding, cutting or polishing. The drive shaft is usually equipped with a safety device or a locking mechanism to ensure the safety of operation when replacing the blade. When the drive shaft or the blade 3 is worn or damaged, the user can easily replace it, which is convenient for maintenance and repair.

[0033] See also Figure 4 The protective cover 7 is made of metal. A center ring 71 with a concave semicircular structure is provided at the center of the protective cover 7. The center ring 71 protrudes from one side of the protective cover 7. The protective cover 7 made of metal enhances the durability and strength of the angle grinder and can better withstand the impact and wear that may be encountered during operation. The center ring 71 with a concave semicircular structure increases the overall structural stability of the protective cover 7, making it more resistant to deformation and damage. The combination of metal material and the concave semicircular structure provides good impact resistance.

[0034] See also Figure 1 An air inlet 4 is provided at the lower outer side of the angle grinder body 1, and a switch 5 is installed on one side of the angle grinder body 1. The setting of the air inlet 4 helps to improve the heat dissipation efficiency of the angle grinder, and helps to cool the motor and internal components by introducing cold air, thereby extending the service life of the equipment and reducing the performance degradation caused by overheating. The placement of the switch 5 enables the operator to control the angle grinder conveniently and quickly, and it is more intuitive and easy to start, stop or adjust the speed. The air inlet 4 is located at the lower outer side of the angle grinder body 1, which is conducive to ensuring good air flow when the angle grinder is placed on a flat surface, while reducing the possibility of dust and debris entering the air inlet.

[0035] Embodiment 2:

[0036] like Figure 1 As shown, on the basis of embodiment 1, the utility model provides a technical solution: the outer side of the handle 2 is arc-shaped, and the outer surface of the handle 2 is covered with a sponge cover. The arc-shaped handle 2 is more suitable for the natural holding posture of human hands, reducing hand fatigue and discomfort during long-term use. The sponge cover provides a soft holding feeling and increases the comfort during operation, especially during the use of an angle grinder with large vibrations, which can reduce the feeling of pressure on the hands. The sponge material has a certain anti-slip effect, and can maintain good holding stability even when the hands are sweating or operating with gloves.

[0037] See also Figure 1 The handle 2 is made of hard plastic material, and the outer surface of the handle 2 is smooth. The handle 2 is an integral injection molding structure. The handle 2 is embedded with a protective cover during the injection molding process. The integral injection molded handle 2 provides a strong structural stability, ensures the connection strength between the handle and the protective cover 7, and reduces the wear or loosening problems caused by long-term use. The hard plastic material makes the handle 2 wear-resistant and chemical corrosion-resistant, and extends the service life of the angle grinder. Through integral injection molding, the production and assembly processes are simplified, the production efficiency is improved, and the production cost may be reduced.

[0038] See also Figure 4 A clamp for installation is sleeved on the center ring 71, and the clamp surrounds the output end of the machine head 6. The clamp can be adapted to machine heads 6 of different models and sizes, providing higher flexibility and interchangeability for the angle grinder. The use of the clamp ensures a stable connection between the machine head 6 and the protective cover 7, which is not easy to loosen even when running at high speed or being impacted by external force.

[0039] During implementation, first, the angle grinder body 1 is connected to the power supply through the power cord. After the power is turned on, the worker installs the protective cover 7, surrounds the clamp around the center ring 71 and the output end of the angle grinder body 1, and locks the clamp. After that, a suitable blade is selected and installed, and then grinding, cutting and other operations are performed. If dust is generated during the operation, the worker can turn on the micro vacuum cleaner 23, and the dust will enter the dust collection bin 22 through the opening for storage, thereby reducing the amount of dust splashing.

[0040] The advantages of this technical solution in practical applications include but are not limited to the following:

[0041] 1. The opening on the handle can receive dust, and at the same time, the micro vacuum cleaner can be turned on to generate negative pressure to absorb the dust, which can avoid dust splashing and make it convenient for workers to clean up;

[0042] 2. A dust suction component is designed inside the original handle, so that the handle can be utilized. On the basis of not increasing the volume of the main body of the angle grinder, the dust suction component is integrated, which can achieve two purposes in one and improve functionality.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
