[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-8 A power tool adapter includes a housing 1, which comprises two housing bodies distributed on the left and right sides, and the housing bodies are fixedly connected by screws.

[0026] Furthermore, the housing 1 contains an input shaft 2 and an output shaft 3. The input shaft 2 is used to connect to a power tool, while the output shaft 3 is used to connect to the rotation output of the power tool. A conversion unit is provided on the output shaft 3, which can output the power tool in a rotating form (drill mode) or in a repetitive impact form (impact drill mode).

[0027] Specifically, a reduction unit is provided in the housing 1. The reduction unit includes an output gear 7 directly connected to the output shaft 3 and several reduction gears 8. Three sets of reduction gears 8 are provided on the outer periphery of the output gear 7. A mounting part 9 is provided on the opposite side of the output gear 7. The mounting part 9 is provided with rotatable reduction gears 8.

[0028] The reduction gear 8 is meshed with the gear, and an internal gear ring 10 is provided on the outside of the reduction gear 8. The internal gear ring 10 meshes with the reduction gear 8 and is fixedly set. When the output gear 7 rotates, the mounting part 9 achieves decelerated rotation under the action of the reduction gear 8, and the output shaft 3 is connected to the mounting part 9 through a key and a keyway, thereby driving the output shaft 3 to rotate.

[0029] Furthermore, in order to switch between electric drill and impact drill, the conversion unit includes a first toothed disc 4, a second toothed disc 5, and a sliding plate 11 for adjustment. The first toothed disc 4 is fixed in the housing 1, and the second toothed disc 5 on the opposite side is connected to the output shaft 3. When the first toothed disc 4 and the second toothed disc 5 come into contact, the second toothed disc 5 will continue to rotate. Therefore, under the continuous action of the toothed discs on both sides, the output shaft 3 outputs in the form of an impact drill.

[0030] Meanwhile, for further adjustable settings, the second gear 5 is disposed in the mounting base 17, and the mounting base 17 is provided with a plurality of protrusions 18 extending toward the first gear 4, and the corresponding second gear 5 is provided with a plurality of top blocks 15.

[0031] Meanwhile, a limiting member 14 is provided on the outer side of the second gear disk 5. The limiting member 14 is provided with a plurality of limiting blocks 21 corresponding to the top block 15. The limiting blocks 21 can rotate between the protrusions 18. After the limiting member 14 is rotated to be misaligned with the top block 15, the second gear disk 5 on the output shaft 3 can abut against the first gear disk 4.

[0032] A groove 12 is provided on the outer shell 1, and a cover 13 is provided inside the outer shell 1 and outside the inner gear ring 10. A groove is also provided on the cover 13. The slider 11 is slidable between the cover 13 and the outer shell 1. The slider 11 is connected to the limiting block 21 through a connecting rod. The output state of the output shaft 3 can be controlled by controlling the position of the slider 11.

[0033] Further describing the output shaft 3, the output shaft 3 is slidably connected in the side plate 16. At the same time, the first gear 4 and the mounting base 17 are provided with springs 6. The springs 6 separate the first gear 4 and the second gear 5 in the stationary state, so that the slider 11 can be freely adjusted without being restricted by the top block 15 and the protrusion 18. Furthermore, an indicator is provided on the housing. The indicator, in conjunction with the slider 11, indicates the current mode of the converter, i.e., whether it is the electric drill mode or the impact drill mode.

[0034] Simultaneously, only when the drill bit on the output shaft 3 is against the wall being drilled, the output overcomes the spring 6 to move the second toothed disc 5 towards the first toothed disc 4 to engage. At this time, the second toothed disc 5 rotates and, in conjunction with the user, remains against the wall, allowing the impact drill mode to be operated.

[0035] Meanwhile, a side plate 16 is provided on one side of the outer shell 1. The side plate 16 is fixed to the cover 13 by screws, and the cover 13 is snapped between the outer shell 1, thus forming a fixed structure.

[0036] The outer casing 1 has threaded holes 19 on both sides for mounting the handle 22. A fixing piece 20 is also provided, with one end of the fixing piece 20 being engaged in the threaded hole 19 and the other end being fixed to the power tool to keep the outer casing 1 continuously fixed.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
