The pressing portion 162 is axially disposed on the axial direction D of the conversion pure 14g, and is slidable in the axial direction D: in the actual body, the body 11G has a "first" positioning groove (7) and a one-position groove G2' respectively adapted to accommodate The positioning unit 164 is placed. When the push button 140 2 is in the position of the brother, the positioning portion 1 (4) stands in the first positioning groove m. When the switch button == the second position, the button portion 164 is located at the 4th position slot. In order to allow the pressing portion 162 to be subjected to the force (4) (4), the docking station 100 of the sub-device may further include an electric lock switch 丨6. The axial 'configuration' parallel axial _-recovery can be used to generate a knife-like collar switch 160 so that the 忿朦 state = energy, in-situ. For example, the second elastic member 17::= shrapnel. When the pressing portion 162 is engaged with the second elastic member π, the second elastic member 170 is deformed to generate a restoring force. In this embodiment, the portable hall includes a bottom plate (as shown in FIG. 1A, the expansion base (10) can further restrict other components to the Z direction), covering the body (4), and FIG. 3B is a schematic diagram 3A. The expansion base of the vertical = electric power when the second position of the rifle change button (10) is changed is shown in FIG. 3A and FIG. 3B. Please refer to Figure 3Α, in the conversion push button 14〇 from the first month / process, the first connector 12. Second; == position of the direction of the movement). At this time, the elasticity of the first elastic member 150 = force: the second connector 130 moves to the lower side (γ direction) in the drawing, and becomes a state as shown in FIG. Referring to Fig. 3'', in the process of switching the inference 14 〇 from the second position, the first connector 120 will move to the right side (χ direction) in the figure. At this time, the first inclined surface 124a pushes the second inclined surface 134a such that the second inclined surface 13 is slidably interlaced with the first inclined surface 124a. As a result, the second connector 13 is forced to rise (-Y direction) and becomes a state as shown in Fig. 3B. 4A is a schematic view of the positioning portion of the locking switch of FIG. 2 located in the first positioning groove, FIG. 4B is a view showing the positioning portion of the locking switch of FIG. 2 retracting the first position groove, and FIG. 4C is a view of FIG. The positioning portion of the locking switch is located in a schematic view of the second positioning slot. In the above description of Figs. 3A and 3B, the description of the lock switch 160 is omitted. The following description will be made in detail with reference to Figs. 4A to 4C. First, referring to FIG. 4A, the positioning portion 164 is located in the first positioning and structurally interferes with the body 110 so that the switching button (10) can be positioned at the first position by the positioning of the positioning portion 164. Then, after the pressing portion 162 is moved by the urging force of the parallel axial direction D in the direction of the pressing portion 162, the second elastic member 17G is elastically deformed, and the fixed (4) I64 is released to interfere with the structure of the body 110. Then, referring to the graphical conversion push button, the second elastic member 17Q drives the lock switch = , , and the private movement 'and the positioning portion 164 enters the second positioning groove (7). ^ 'The clamping portion 164 structurally interferes with the body U〇 such that the switching push button H0 can be positioned at the second position by the positioning of the positioning portion 164. This connection can be completed by a single switch, which can be used to switch between the first and the next. This hunting is interfered by the structure of the locking switch and the body, so that the first connection and the ί = unit can be switched between positioning. Therefore, the accurate positioning of the original creation has been disclosed in the above embodiments, but it is not intended to limit the technical knowledge of the technical field in the technical field, without departing from the creation of the insurance 2 and the dry circumference, when Make some changes and refinements, so this is subject to the definition of the patent application scope attached to it.
