An included angle between an axial direction of the storage hole 211 and an axial direction of an output end of the hand-held electric power tool 300 is less than 10, such as 3, 5 and 8, that is to say, the axial direction of the storage hole 211 and the axial direction of the output end of the hand-held electric power tool 300 are approximately the same, and almost parallel, and this arrangement is convenient for the user to insert and remove the replacement head 400.

[0099] Continuously referring to FIG. 2, in some embodiments of the present application, a middle portion of the storage hole 211 is provided with an avoidance opening 212, and when a plurality of storage holes 211 are provided, the plurality of storage holes 211 are distributed at intervals in a first direction, the avoidance opening 212 of each storage hole 211 is penetrated, and the first direction is perpendicular to the axial direction of the storage hole 211. The arrangement of the avoidance opening 212 is convenient for taking a replacement head 400 with a short length inserted in the storage hole 211, and the replacement head 400 with the short length is easy to be hidden in the storage hole 211, which is inconvenient to take the replacement head at this time. However, the middle portion of the storage hole 211 is provided with the avoidance opening 212, and the user may push the replacement head 400 out of the storage hole 211 from the avoidance opening 212. Moreover, the avoidance opening 212 divides the storage hole 211 into two sections, and the two sections of the storage hole 211 may be respectively used for inserting the replacement head 400. In addition, when a plurality of storage holes 211 are provided, and the avoidance opening 212 of each storage hole 211 is penetrated, this arrangement makes each penetrated avoidance opening 212 form a larger opening, which is convenient for the user to operate.

[0100] The embodiment of the present application further provides a hand-held electric power tool assembly, the hand-held electric power tool assembly includes a hand-held electric power tool 300 and the replacement head external hanging device according to any one of the solutions above, wherein the binding mounting belt 100 of the replacement head external hanging device is wound on the hand-held electric power tool 300, and the storage member 200 of the replacement head external hanging device is mounted on the hand-held electric power tool 300 through the binding mounting belt 100.

[0101] After considering the specification and practicing the present disclosure, a person skilled in the art may easily conception of other implementations of this application. The present application is intended to cover any variations, uses, or adaptive changes of the present application. These variations, uses, or adaptive changes follow the general principles of the present application and include common general knowledge or common technical means in the art, which are not disclosed in the present application. The specification and the embodiments are considered as merely exemplary, and the scope and spirit of this application are pointed out in the following claims.

[0102] It should be understood that the present application is not limited to the precise structures described above and shown in the drawings, and various modifications and changes can be made without departing from the scope of the present application. The scope of the present application is subject only to the appended claims.
