[0024] Example

[0025] like Figures 1 to 4As shown, the present invention proposes a surface treatment device for metal products, including a handheld grinder 1 and a grinding head 2 movably mounted on the end of the handheld grinder 1. The grinding head 2 is used for surface treatment of metal products, and its mounting rod 21 is inserted into the machine body for fixation. A storage groove 11 is provided at the end of the handheld grinder 1 away from the grinding head 2; the storage groove 11 is provided with a storage mechanism for storing multiple grinding heads 2.

[0026] Among them, such as Figures 2 to 4 As shown, the handheld grinder 1 and the storage box 3 are equipped with a locking mechanism that allows the storage mechanism to disengage from the storage slot 11. The storage mechanism includes the storage box 3 located within the storage slot 11. The storage box 3 has multiple slots 31 for storing grinding heads 2. The slots 31 are used to store the grinding heads 2, and the mounting rods 21 of the grinding heads are fixed in place with the support plate 32 and the slot 321. The inner wall of the slots 31 is marked with the specifications and models of the grinding heads 2 to ensure efficient and quick retrieval during use. One end of the grinding head 2 is fixedly connected to the mounting rod 21, which is inserted into and locked to the end of the handheld grinder 1. Matching threads are machined on the mounting rod 21 and the end of the handheld grinder 1. The mounting rod 21 is rotated to screw it into the end of the handheld grinder 1. This connection method is firm and can withstand a large torque to ensure that the grinding head 2 will not loosen under high-intensity operation. The interior of each placement slot 31 is fixedly connected with a support plate 32 that holds the mounting rod 21. The support plate 32 has a slot 321 that tightly holds the mounting rod 21. The slot 321 is opened on the support plate 32. By tightly engaging the mounting rod 21, the grinding head 2 is fixed in the storage box 3.

[0027] Secondly, the handheld grinder 1 features an integrated design with smooth lines that conform to modern tool aesthetics. Furthermore, when the storage box 3 retracts into the storage slot 11, the surface of the handheld grinder 1 remains flat, thus not affecting grip or grinding operations.

[0028] In addition, such as Figures 1 to 4As shown, the locking mechanism includes a sliding hole 13 at the end of the handheld grinder 1 away from the grinding head 2. A first mounting groove 36 corresponding to the sliding hole 13 is provided on the storage box 3. The first mounting groove 36 is located on the storage box 3, corresponding to the sliding hole 13, and houses a second spring 37 to provide a reset elastic force for the button 35. The second spring 37 is fixedly connected inside the first mounting groove 36. The second spring 37 is located on the storage box 3, corresponding to the sliding hole 13, and houses a second spring 37 to provide a reset elastic force for the button 35. A button 35, which moves through the sliding hole 13, is fixedly connected to the end of the second spring 37 away from the inner wall of the first mounting groove 36. The button 35 is located on the storage box 3, corresponding to the sliding hole 13, and houses the second spring 37 to provide a reset elastic force for the button 35. The end of button 35 away from the second spring 37 is designed with a spherical plug arc surface to reduce friction when pressed, making button 35 easier to trigger; at the same time, the spherical structure fits more tightly with the sliding hole 13, and can form a stable locking state after being inserted into the first mounting slot 36, preventing the storage box 3 from accidentally popping out due to vibration during use, and enhancing the stability of the locking mechanism.

[0029] It is worth noting that, such as Figure 3 and Figure 4 As shown, the storage slot 11 has a pair of limiting slide grooves 12 inside. The limiting slide grooves 12 are formed on the storage box 3 and correspond to the sliding hole 13. A second spring 37 is installed inside to provide a reset elastic force for the button 35. One end of the storage box 3 is fixedly connected to a pair of limiting blocks 38 that snap into the corresponding limiting slide grooves 12.

[0030] Furthermore, such as Figures 2 to 4 As shown, the storage box 3 also has multiple second mounting slots 33 arranged in a circular array. Each second mounting slot 33 is located on the storage box 3 and contains a first spring 34, which is connected to the inner wall of the storage slot 11 to provide the elastic force for the storage box to pop out. Each second mounting slot 33 has a first spring 34 fixedly connected inside. The first spring 34 is installed within the second mounting slot 33, with one end connected to the storage box 3 and the other end connected to the inner wall of the storage slot 11. Pressing the button 35 charges the spring, and unlocking it pushes the storage box 3 out. The end of the first spring 34 furthest from the inner wall of the second mounting slot 33 is fixedly connected to the inner wall of the storage slot 11.

[0031] In this embodiment, when using the surface treatment device for metal products, the handheld grinder 1 is held. When the grinding head 2 needs to be replaced, the button 35 is pressed. The button 35 compresses the second spring 37 through the sliding hole 13, causing the button 35 to retract into the first mounting groove 36, thereby releasing the lock on the storage box 3. At this time, under the elastic action of the first spring 34, the storage box 3 automatically pops out from the storage groove 11, and the limiting block 38 slides in the limiting sliding groove 12 to ensure the stability of the pop-out of the storage box 3.

[0032] After the storage box 3 pops out from the storage slot 11, multiple grinding heads 2 can be seen in the placement slots 31. The mounting rod 21 of each grinding head 2 is tightly locked by the slot 321 on the support plate 32. When removing the required grinding head 2, pull out the mounting rod 21 forcefully to disengage it from the slot 321. When installing a new grinding head 2, insert the mounting rod 21 into the end of the handheld grinder 1 to lock it, and then push the storage box 3 back into the storage slot 11. The button 35, under the action of the second spring 37, re-engages into the first mounting slot 36, completing the locking of the storage box 3. During the process of pushing the storage box 3 back, the limiting block 38 slides in the limiting slide groove 12, playing a guiding and limiting role. At the same time, the first spring 34 is compressed to ensure that the storage box 3 is securely stored in the storage slot 11.
