Description

Technical Field

[0001] This application relates to the field of power tool technology, and more particularly to a handheld angle grinder with a reversible battery pack orientation. Background Technology

[0002] Handheld angle grinders, especially those powered by battery packs, typically have a housing consisting of a grip and feet, with the battery pack inserted into the feet. However, the feet are usually fixedly connected to the grip or are an integral part of it, preventing the feet from rotating relative to the grip. Consequently, the battery pack's position remains fixed after installation. During use, the battery pack's position can sometimes interfere with the user's wrist, hindering operation. For example, angle grinders are used for cutting and grinding, requiring different grip positions. If the wrist is positioned above the battery pack, the arm will tilt relative to the grip to avoid it, making it difficult to apply force and causing instability due to the battery pack's weight. Alternatively, the battery pack may bump against objects, affecting operation. Therefore, there is a need for an angle grinder that allows for repositioning the battery pack to avoid obstructing the user's workspace. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a handheld angle grinder with an adjustable battery pack orientation.

[0004] The handheld angle grinder includes a housing and a battery pack. The housing includes a main body, a grip, and feet. The main body extends perpendicularly to the grip. The main body houses a motor. The grip is located below the main body. The battery pack is detachably mounted on the feet, and the feet are rotatably mounted on the grip, giving the battery pack a first position and a second position.

[0005] Furthermore, the footplate and the battery pack are rotatable 90° relative to the grip. The main body has a first axial direction, and the insertion direction of the battery pack and the footplate is a second axial direction. In the first position, the first axial direction is parallel to the second axial direction. In the second position, the first axial direction is perpendicular to the second axial direction. The battery pack has a long side and a short side, and the long side of the battery pack is parallel to the second axial direction. The handheld angle grinder has a cutting mode and a grinding mode. In the cutting mode, the battery pack is in the first position, and in the grinding mode, the battery pack is in the second position.

[0006] Furthermore, the gripping part has an end connected to the foot plate, the end being provided with a groove, the foot plate having a protrusion, the protrusion of the foot plate being engaged in the groove of the gripping part, the protrusion being movable along the groove, so that the foot plate can rotate relative to the gripping part.

[0007] Furthermore, the grip portion is also provided with a button and an elastic element. The button includes an operating part and an action part. The action part is located inside the grip portion, and the operating part protrudes from an opening in the grip portion. The elastic element is used to reset the button. The button has a locked position and an unlocked position. In the locked position, the operating part protrudes from the surface of the grip portion, and the action part is located inside the grip portion. The action part is used to block the protrusion of the footplate, so that the footplate is fixed relative to the grip portion. In the unlocked position, the action part avoids the protrusion of the footplate, so that the footplate can rotate relative to the grip portion.

[0008] Furthermore, the slot of the grip portion has a gap, and the protrusion of the foot plate has a first groove and a second groove. When the first groove coincides with the gap, the actuating part of the button is located at the gap and the first groove, and the battery pack is located at the first position after being inserted into the foot plate. When the actuating part of the button is located at the gap and the second groove, the battery pack is located at the second position after being inserted into the foot plate.

[0009] Furthermore, the end of the gripping part has a first bottom wall and a second bottom wall located below the first bottom wall, the first bottom wall and the second bottom wall are connected by a side wall, and the first bottom wall, the second bottom wall and the side wall form the slot with the opening facing outward.

[0010] Furthermore, the protrusion of the foot plate extends radially inward and engages in the slot.

[0011] Furthermore, the width of the first bottom wall in the radial direction is greater than the width of the second bottom wall.

[0012] Furthermore, the grip and the foot plate are each composed of two half-shells joined together.

[0013] Beneficial effects: The feet of this angle grinder can rotate relative to the grip, thereby allowing the battery pack, which is detachably mounted to the feet, to have a first position and a second position. When operating the angle grinder, the user can adjust the orientation of the battery pack to prevent the top of the battery pack from pressing against the user's wrist and obstructing operation.

[0024] like Figures 1 to 7 As shown, this utility model discloses a handheld angle grinder 100 with an adjustable battery pack orientation. Figure 1 As shown, the handheld angle grinder 100 includes a housing and a battery pack 4. The housing includes a main body 1, a grip 2, and feet 3. The grip 2 is located below the main body 1, and the extending direction of the main body 1 is perpendicular to the extending direction of the grip 2. The main body 1 houses a motor 7, the output shaft of which is in the same direction as the extending direction of the main body 1 and is connected to the working head. A protective cover is also connected to the main body 1 to at least partially cover the working head. The battery pack 4 is detachably mounted to the feet 3, which is rotatably mounted to the grip 2, allowing the battery pack 4 to have a first position and a second position.

[0025] Specifically, the footplate 3 and battery pack 4 can rotate 90° relative to the grip 2. The main body 1 has a first axis, and the insertion direction of the battery pack 4 and the footplate 3 is a second axis. Figure 2 As shown, in the first position, the first axis of the battery pack 4 is parallel to the second axis; as Figure 3 As shown, the battery pack 4 is in the second position, with the first axis perpendicular to the second axis.

[0026] Typically, the battery pack 4 has a long side and a short side, with the long side of the battery pack 4 parallel to the second axis. The handheld angle grinder 100 has a cutting mode and a grinding mode.

[0027] In the cutting working mode, such as Figure 2 As shown, the battery pack 4 is in the first position. At this time, the user holds the grip part 2, and the long side of the battery pack 4 is below the wrist. Therefore, the top of the battery pack 4 will not hit the user's wrist, and the user's forearm can be as close to the grip part 2 as possible, which makes it easier to exert force when cutting objects.

[0028] In the polishing work mode, such as Figure 3 As shown, the battery pack 4 is in the second position. At this time, when the user holds the grip 2, the long side of the battery pack 4 is also below the wrist, and the top of the battery pack 4 will not touch the user's wrist, making it easier for the user to operate the machine.

[0029] In other words, whether in cutting or grinding mode, the battery pack 4 can be adjusted to a position that does not obstruct the user's operation.

[0030] Specifically, such as Figure 4 As shown, the gripping part 2 has an end connected to the foot plate 3, and the end is provided with a groove 20. The foot plate 3 has a protrusion 30, and the protrusion 30 of the foot plate 3 is engaged in the groove 20 of the gripping part 2. The protrusion 30 can move along the groove 20, so that the foot plate 3 can rotate relative to the gripping part 2.

[0031] Combination Figure 6 and 7 As shown, the gripping part 2 is a hollow cylindrical shape, with an annular first bottom wall 21 at its end and an annular second bottom wall 22 located below the first bottom wall 21. The width of the first bottom wall 21 in the radial direction is greater than the width of the second bottom wall 22. The first bottom wall 21 and the second bottom wall 22 are connected by a side wall 23, and the first bottom wall 21, the second bottom wall 22, and the side wall 23 form an outward-facing slot 20. The foot plate 3 has an annular protrusion 30 extending radially inward, which engages with the slot 20.

[0032] like Figure 4 and 7As shown, the grip 2 is also provided with a button 5 and an elastic member 6. The button 5 includes an integrally formed operating part 51 and an action part 52. The action part 52 is located inside the grip 2, and the operating part 51 protrudes from the opening 24 of the grip 2. The elastic member 6 is used for resetting the button 5. The button 5 has a locked position and an unlocked position. In the locked position, the operating part 51 protrudes from the surface of the grip 2, and the action part 52 is located inside the grip 2. The action part 52 is used to block the protrusion 30 of the foot plate 3, so that the foot plate 3 is fixed relative to the grip 2. In the unlocked position, the operating part 51 is pressed to make the action part 52 avoid the protrusion 30 of the foot plate 3, so that the foot plate 3 can rotate relative to the grip 2.

[0033] Specifically, the gripping part 2 is composed of two half-shells joined together, and the joint between the left and right half-shells forms a slot 201 with a gap 201, such as... Figure 4 As shown. The foot plate 3 is also composed of two half-shells 31 and 32 joined together. The protrusion 30 of the foot plate 3 has a first groove 301 and a second groove 302, as shown. Figure 5 As shown. When the first groove 301 coincides with the empty position 201, the actuating part of the button 5 is located at the empty position 201 and the first groove 301, and the battery pack 4 is inserted into the foot plate 3 and located in the first position. When the actuating part of the button 5 is located at the empty position 201 and the second groove 302, the battery pack 4 is inserted into the foot plate 3 and located in the second position.

[0034] The operation of adjusting the direction of the battery pack 4 of the angle grinder 100 is as follows: In the initial state, the battery pack 4 is in the first position or the second position, and the button 5 is in the locked position.

[0035] Pressing the operating part 51 of button 5 puts button 5 in the unlocked position. The actuating part 52 of button 5 leaves the empty position 201 of the slot 20, compressing the elastic element 6. Then, rotate the foot plate 390° and release button 5. The restoring force of the elastic element 6 returns the actuating part 52 to the empty position 201 of the slot 20, and button 5 is back in the locked position. At this time, the battery pack 4 is switched to the second position or the first position.
