The operating element 720 is arranged on the housing 105 in a rotation direction switch manner and can be operated or moved laterally, or in the lateral direction 499, or in the lateral directions 1102, 1103 of the shaft 305. By exemplarily loading the operating element 720 to the right in the lateral direction 1102, or to the right in the illustration, the spring element 1020 is loaded toward and thus compressed towards the support element 1099 fixed relative to the housing. Here, the operating element 720 moves to the right in the illustration, wherein the loading bar 1030 loads the locking element 1199 of the tool library 150 counterclockwise and thus rotates the tool library 150 in the circumferential direction 1101, the locking element being arranged between the loading bars 1030, 1031. Furthermore, Figure 12 The receiver 1110, which is assigned to the application tool library 150, is used for arranging... Figure 1 The multiple application tools 196 include application tools 191, 192, 193, 194, and 195.
[0081] Figure 13 It shows a library of 150 application tools. Figures 1 to 4 The handheld power tool 100, according to another embodiment, has a loading bar 1210 only in the circumferential direction 1101. Here, the loading bar 1210 is preferably constructed along the overall longitudinal extension direction of the application tool library 150, or the longitudinal direction 1019. The loading bar 1210 is loaded by the user, especially by the finger 1220 of the user of the handheld power tool 100, which causes the application tool library 150 to rotate in the circumferential direction 1101. Here, the rotation of the application tool library 150 in the direction of arrow 1201, or clockwise, is caused by the rotation or loading of the finger 1220, especially the user's index finger. Here, the application tool library 150 rotates in the circumferential direction 1101, especially clockwise, for selecting application tools.
