Abstract

(57) [Summary] [Object] The present invention relates to a paper clip support device for an orbital sander, and its purpose is to provide an inexpensive orbital sander with good assembly work by devising the shapes of a base and a support. Is. [Structure] Grooves 9 are integrally formed on both ends 5 of the upper surface of a base 6, and a protrusion 11 is integrally provided on a lower end of a column 7.
1 and the groove 9 press the sanding paper to rotatably hold the paper clip 2 fixed to the base 6.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an orbital sander having an improved paper clip support structure.

[0002]

[Prior art]

 A conventional technique will be described with reference to FIGS. A housing 1 having a built-in motor (not shown), a column 7 for transmitting the rotational motion of the motor to the base 6 as a circular orbital motion, and a torsion bar 8 provided with both ends 5 of the upper surface of the base 6 and imparted with a torsional force. And a pair of paper clips 2 for pressing and fixing sanding paper (not shown) to the base 6, and the paper clip 2 being rotatably supported, and fixed to the base 6 together with the support column 7 with screws 4. The clip holder 3 is provided.

[0003]

[Problems to be solved by the device]

 Conventionally, the gap between the inner diameter 3a of the clip holder 3 and the outer diameter 2a of the paper clip 2 is set to be large so that the clip holder 3 and the paper clip 2 can be easily connected. As shown in FIG. 9 and FIG. 10, 3 is misaligned in the direction of arrow A or twisted in the direction of arrow B, resulting in poor assembly workability. Also, since the clip holder 3 is made of a thin iron plate, it is difficult to handle. Furthermore, there was a problem that the cost was high because there were many components.

An object of the present invention is to eliminate the above-mentioned problems and to provide an inexpensive orbital sander having a simple structure and good assembling workability.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the orbital sander of the present invention has grooves for supporting a paper clip integrally formed at both ends of the upper surface of the base.

[0006]

[Action]

 In the orbital sander configured as described above, first insert both ends of the paper clip into the groove of the base and hang it, then fix the column to the top surface of the base with screws etc. It can be rotatably clamped between and.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to FIGS. In the figure, four U-shaped grooves 9 are integrally provided on both upper end portions 5 of a base 6 which supports a paper clip 2 formed by a torsion bar 8 which imparts a twisting force. A projecting portion 11 is integrally provided on a lower end portion 10 of the column 7, which transmits a rotational movement to the base 6 as a circular orbital movement. Next, the assembling work of the sandpaper fixing device for the orbital sander configured as described above will be described. First, both ends of the paper clip 2 are put into the grooves 9 of the base 6 and scratched. Next, while pressing the paper clip 2 in the direction of the arrow C, the support 7 is fastened and fixed to the upper surface of the base 6 with the screw 4. With such a simple operation, the paper clip 2 is rotatably sandwiched between the groove 9 of the base 6 and the projection 11 of the column 7 to be assembled. Another embodiment is shown in FIGS. A groove 9 having a concave shape is provided in the base 6 to support the paper clip 2 in the groove 9. With such a configuration, the same effect as that of the above embodiment can be obtained.

[0008]

[Effect of device]

 According to the present invention, since the clip holder is not necessary, the workability of assembling the paper clip is improved and an inexpensive orbital sander can be provided.
