no. 1 Embodiment approach

[0113] Below, refer to Figure 1 ~ Figure 3 The first embodiment of the present invention will be described in detail. Such as figure 1 As shown, the grinding machine 101 of the present embodiment mainly includes an electric motor (for convenience, its illustration is omitted) and a generally cylindrical motor housing for accommodating the electric motor and the power transmission mechanism (for convenience, its illustration is omitted). 103, and a grinding part 105, the grinding part 105 is provided in the axial direction of the motor housing 103 in a state extending downward from the motor housing 103 ( figure 1 the lower end side of the upper and lower directions). The motor housing 103 constitutes the main body of the tool, and corresponds to the "cylindrical housing" of the present invention. The power transmission mechanism decelerates and transmits the rotational power of the motor to the grinding unit 105, and corresponds to the "drive mechanism" of the present inve...

no. 2 Embodiment approach

[0131] Next, refer to Figure 4 and Figure 5 The structure of the auxiliary handle according to the second embodiment of the present invention will be described. Since there is no particular change in the overall structure of the sander 101 equipped with the auxiliary handle compared with the first embodiment, the same symbols are used and detailed descriptions thereof are omitted. In addition, such processing is not limited to the second embodiment, and is also the same in the third and subsequent embodiments.

[0132] The auxiliary handle 141 of the present embodiment mainly includes a ring-shaped handle connection part 143 and a grip part 147 for the operator to grasp in structure. The handle connection part 143 surrounds the handle formed on the motor housing 103 of the grinder 101 on the mounting part 115. The auxiliary handle 141 corresponds to the "movable handle" of the present invention, the handle connection part 143 corresponds to the "handle part" of the presen...

no. 3 Embodiment approach

[0141] Refer below Figure 6 and Figure 7 A third embodiment of the present invention will be described. This embodiment is a modified example of the auxiliary handle 141 of the second embodiment described above. That is, in this embodiment, the only difference from the second embodiment is that, on the auxiliary handle 141, nuts 151 are provided on the bases 145a, 145b of the handle connection part 143, and bolts 153 are provided on the grips. The other configurations of the grip 147 are the same as those of the second embodiment. As shown in the figure, the stepped through hole 147a with the hexagonal hole runs through the center of the grip portion 147, and the bolt 153 passes through the stepped through hole 147a with the hexagonal hole in a non-rotatable manner and is screwed on Nut 151. However, a form in which the bolt 153 is embedded in the grip portion 147 may also be employed.

[0142] According to the third embodiment having the above-mentioned structure, the ...

Abstract

It is an object of the invention to improve usability of a sander. The sander includes a rotary working surface (105), a driving mechanism that is disposed above the rotary working surface (105) in a direction of the rotation axis of the rotary working surface (105) and rotationally drives the rotary working surface (105), a cylindrical housing (103) that houses the driving mechanism, and a movable handle (117) that is mounted on a surface of a cylindrical part of the cylindrical housing (103). The movable handle (117) can be turned around the central axis of the cylindrical housing (103) and can be fixed at an arbitrary position in a circumferential direction of the cylindrical housing (103).

Description

technical field [0001] The invention relates to a grinder for grinding operations. Background technique [0002] Japanese Patent Laid-Open Publication No. 2004-167657 (Patent Document 1) discloses a grinder for grinding a workpiece. The grinding machine disclosed in this gazette is provided with a handle portion, which is integrally formed on the upper part of the housing of the housing with the drive mechanism inside as the main handle. In addition to the auxiliary handle, the housing is also provided with a handle as a movable handle. Grip. [0003] The auxiliary handle has a handle support part and a grip part structurally. The handle support part is installed on the shell of the shell and can be disassembled freely. It can move freely and can be fixed at any position within its moving range. In addition, the handle support portion can change its orientation within a range of 180° along the circumferential direction of the housing portion, thereby allowing the operator...
