Description

Small-sized angle grinder

Technical Field

The utility model relates to the field of electric tools, in particular to a small angle grinder.

Background

An angle grinder is a common grinding type tool used for grinding, cutting, etc. metals. For large-size workpieces, a high-power large-sized angle grinder is usually selected, and two hands are required for operation; while for smaller or workpieces requiring finishing, a small angle grinder needs to be selected. In general, a motor of the small angle grinder is arranged in a head shell, so that the length is greatly reduced, the holding outer diameter is also greatly reduced without arranging the motor in a handle, and the operation comfort is improved. There are few small angle grinders available on the market today that are not reasonably designed, for example, when the small angle grinder is placed on the table top after use, the abrasive/cutting blade contacts the table top, potentially causing damage to the abrasive/cutting blade or the table top.

Referring to fig. 1 to 3, the present utility model provides a small-sized angle grinder, which includes a housing 1, a motor 2 accommodated in the housing, an output shaft 3 driven by the motor 2 (which may be directly driven or may have a speed change mechanism provided therebetween), and a battery pack 6 for supplying power to the motor, wherein the housing 1 includes a motor accommodating portion 11, a holding portion 12, and a battery pack connecting portion 13, the motor 1 is accommodated in the motor accommodating portion 11, the output shaft 3 protrudes from the battery accommodating portion, and the output shaft 3 is configured to be mounted with a work table 4, such as a grinding sheet or a cutting sheet, for grinding or cutting a workpiece. In this embodiment, the motor 2 directly drives the output shaft 3, and the axis of the motor 2 is collinear with the axis of the output shaft 3; in other embodiments, a speed change mechanism may be disposed between the motor 2 and the output shaft 3, and the axis of the motor 2 and the axis of the output shaft 3 may be disposed in parallel.

The angle grinder 1 further comprises a support element 5, wherein the support element 5 is movably arranged on the motor accommodating part 11 and has a first position and a second position, and the support element 5 is in a storage state when being positioned at the first position and is basically abutted against the shell so as not to influence the operation of a user as much as possible; when the supporting element 5 is located at the second position, the supporting element and the battery pack 6 or the battery pack connecting part 13 jointly support the small-sized angle grinder, so that the working head (the grinding sheet or the cutting sheet) is in a suspended state and cannot contact with the tabletop, and the workbench or the tabletop is damaged.

Specifically, the motor housing 11 includes a first half shell 111 and a second half shell 112, the two half shells being fixed by bolts, one of the first half shell 111 and the second half shell 112 being provided with a mounting hole 110. The support member 5 includes a pivot portion 51 rotatably mounted to the mounting hole 110 (or the motor housing portion 11), and a support portion 52 configured to support the small-sized angle grinder together with the battery pack 6 or the battery pack connection portion 13. The number of the supporting parts 52 in the present embodiment is two, the battery pack connection part includes a sliding rail (not shown) that cooperates with the battery pack, and the arrangement direction of the two supporting parts 52 is parallel to the extending direction of the sliding rail (i.e., the installation direction of the battery pack) so as to jointly play a supporting role.

Referring to fig. 4, optionally, the motor housing portion 11 further includes a first limiting portion 114 and a second limiting portion 115, where the first limiting portion 114 and the second limiting portion 115 are located on opposite sides of the mounting hole, respectively. The first limiting portion 114 prevents the support element 5 from being out of the first position when the support element 5 is in the first position, and the second limiting portion 115 prevents the support element 5 from being out of the second position when the support element 5 is in the second position. In the present embodiment, the first stopper 114 and the second stopper 115 are formed in a convex structure.

The supporting element 5 further comprises a bridging portion 53 connected with the two supporting portions 52, and the bridging portion 53 and the supporting portions 52 are both curved, so that the supporting element 5 can be attached to the outer contour of the housing 1 when being located at the first position, and normal operation of a user is not affected.

When the support member 5 is in the second position, the support member 5 is disposed at an obtuse angle with respect to the grip portion 12 as viewed in a direction parallel to the axis of the output shaft 3, and the battery pack 6 (or the battery pack mounting portion 13) is disposed at an obtuse angle with respect to the grip portion 12, so that the small-sized angle grinder is substantially isosceles trapezoid (as viewed in the axis direction of the output shaft) at this time, to ensure stability of support. The support has a first support feature and the battery pack has a second support feature (here one edge 30 of the battery pack) that is coplanar with the second support feature to support the angle grinder in plane a. The first support feature corresponds to a support surface 520, the support surface 520 being proximate to the bridge 53 and distal to the pivot 51; the distance between the two support surfaces 520 defines the maximum width of the support member 5, so that the complete machine can be supported more stably with the battery pack 6 (or the battery pack mounting portion 13).

The small-sized angle grinder comprises a switch (not shown) for controlling the motor 2 and a trigger piece 7 acting on the switch, wherein the trigger piece 7 is arranged on a first side of the holding part 12, when the supporting element 5 is positioned at a first position, the supporting part 52 is positioned on a second side of the holding part 12, and the first side and the second side are oppositely arranged, namely, a finger of a user operating the trigger piece can be freely operated without being interfered by the supporting part 52. Preferably, when the support member 5 is in the first position, the ratio of the distance from the bridge 53 to the motor housing 11 to the distance from the bridge 53 to the battery pack connection 13 is not more than 1/3, i.e. the support is positioned further forward. Making the hands of the user less accessible and disturbed by them. More preferably, since no motor is required in the grip portion, it is suitably recessed to receive the bridge portion and the support portion without any interference with the user's hand.

The present utility model is not limited to the above-mentioned embodiments, but is not limited to the above-mentioned embodiments, and any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical matters of the present utility model can be made by those skilled in the art without departing from the scope of the present utility model.
