[0034] The present invention will be further described below with reference to the accompanying drawings.

[0035] like Figure 1-6 、 Figure 11 The multifunctional laser emitting device shown in the figure comprises a laser emitting device 101 for emitting laser light. The laser emitting device 101 is provided at Figure 8-10 The core 100 shown in the figure is also provided with a functional device 102 and a line switch 103 and a function switch 104 for controlling the laser emitting device and the functional device respectively. The functional device and the laser emitting device are distributed at different circumferential positions, and the line switch and the function switch are also distributed at different circumferential positions. The outer side of the core 100 is equipped with a shell 200 that rotates circumferentially. The shell 200 is provided with a window 201 and a switch contact 202. The circumferential rotation of the shell allows the switch contact to selectively touch the line switch and the function switch. When the line switch turns on the circuit to make the laser emitting device work, the laser emitting device corresponds to the window. The window is preferably equipped with a frame 204 on the shell and a transparent plate on the frame. Accordingly, by relatively rotating the core 100 and the shell 200, the switch contact can selectively touch the line switch or the function switch, thereby turning on the corresponding circuit to make the laser emitting device or the functional device work. Figure 1-2 The figure shows the working state of the line. Figure 3 Shown in closed state, Figure 4 The lighting state is shown, and, in order to prompt the operation, a corresponding mark is set on the base so that the mark is turned to the corresponding window to start the corresponding function. Moreover, the functional device can be two or more.

[0036] Preferably, the housing 200 is cylindrical. Figure 8-10As shown, the core 100 includes a base 105, a top cover 106, and an inner core 107 located between the base and the top cover. The laser emitting device 101 and the functional device 102 are arranged on the inner core 107. The two ends of the outer shell 200 are rotatably assembled with the base 105 and the top cover 106 respectively. Moreover, the base and the top cover are circular, and the diameters of the two are the same as the diameters of the two ends of the outer shell, so that the entire laser emitting device appears cylindrical in appearance. For ease of assembly, the top cover 106 is cylindrical and extends downward to be assembled with the base 105. The inner core 107 is assembled between the base 105 and the top cover 106, and the circuit board 117 is assembled at the position where the lower end of the top cover 106 is adjacent to the base 105 (see Figure 6 ), the laser emitting device 101 and the functional device 102 are located on the upper side of the circuit board. In order to supply power, a battery compartment 118 is assembled on the base to accommodate batteries 119.

[0037] See also Figure 5 To position the housing 200 at various functional locations, the housing 200 and the core 100 are provided with positioning structures. These positioning structures include positioning protrusions 203 and positioning slots 108, respectively, provided on the housing and the core. When the switch contact 202 selectively activates the throw switch or function switch, the positioning protrusions are located in the positioning slots. Specifically, the positioning protrusions 203 are provided on the inner wall of the housing 200 or on the frame 204, and the positioning slots 108 are provided on the outer wall of the extension portion of the top cover 106.

[0038] See also Figure 5 To ensure smooth alignment between the positioning groove and the positioning protrusion, elastic arms 109 are provided on either side of the positioning groove 108. These curved arms 109 form guide surfaces that guide the positioning protrusion into or out of the groove. Therefore, the positioning protrusion can smoothly slide over the guide surfaces from either side of the positioning groove and settle into the groove, or smoothly exit the groove. For reliable positioning, positioning structures are provided at both ends of the inner core.

[0039] Moreover, the housing 200 and the core 100 are positioned at Figure 3 The closed position shown is offset from the position where the switch contacts actuate the line-casting switch and the function switch. That is, the switch contacts do not actuate the line-casting switch and the function switch in this closed position, thereby maintaining the laser emitting device in the closed state. A product identification mark may be provided on the core, particularly at a position corresponding to the window in the closed position, to facilitate product identification through the transparent window.

[0040] See also Figure 8The core 100 is provided with an ambient light 110, particularly on the downward-facing surface of the top cover 106. A button 111 is provided on the top cover, and a push button switch (not shown) for controlling the ambient light is provided below the button 111. By pressing the button to activate the push button switch, the ambient light can be turned on and off, and its lighting mode can be adjusted. The ambient light is preferably a COB light strip.

[0041] See also Figure 7 In order to enable the laser emitting device to self-calibrate horizontally and vertically during operation, the laser emitting device is suspended on the inner core 107 of the core body 100 by two vertical axes 112. When the entire laser emitter tilts, the laser emitting device relies on gravity to swing around the axis to self-calibrate; in order to protect the laser emitting device and prevent the laser emitting device from shaking, being damaged or misaligned, a locking structure is configured for the laser emitting device. When the laser emitting device corresponds to the window, the locking structure loosens the laser emitting device, and when the laser emitting device deviates from the window, the locking structure locks the laser emitting device.

[0042] See also Figure 7 Specifically, the locking structure includes a support plate 113 located at the lower side of the laser emitting device 101, and an elastic element 114 that applies an upward elastic force to the support plate 113. A pressing tongue 115 is provided on the support plate, and a protrusion is provided on the outer shell 200. In order to simplify the structure, a positioning protrusion is preferably used as the protrusion; when the laser emitting device 101 corresponds to the window working, the protrusion presses the pressing tongue 115 to make the support plate release the laser emitting device, and the laser emitting device can calibrate itself. In order to rotate smoothly and make the protrusion press the pressing tongue during rotation, the protrusion and the pressing tongue cooperate through an inclined surface, and the inclined surface is preferably provided on the pressing tongue; when the laser emitting device deviates from the window and closes, the protrusion deviates from the pressing tongue and the support plate is supported by the upward elastic force of the elastic element to lock the laser emitting device to prevent the laser emitting device from shaking.

[0043] See also Figure 7 One side of the support plate 113 is rotatably connected to the core 100 (e.g., the inner core). In a specific implementation, one side of the support plate can also be rotatably connected to another structural member fixed to the core (e.g., a circuit board 117). A detent 115 is provided on the other side of the support plate 113, and an elastic element 114 is supported on the underside of the support plate 113. A guide post 116 is provided on the inner core 107 of the core 100, and the support plate 113 is sleeved on the guide post. The elastic element 114 is a helical compression spring sleeved on the guide post.

[0044] Functional device 102 includes a lighting fixture. When the functional switch connects the circuit to activate the functional device, the lighting fixture illuminates the corresponding window. Given the aforementioned technical inspiration for controlling the on / off and lighting mode of the ambient light by pressing a button to activate a pushbutton switch, the lighting mode of the lighting fixture can also be adjusted by pressing a button to activate a pushbutton switch.

[0045] The lighting lamp mentioned above is a functional device, and in specific implementation, it can also be a speaker, a radio, etc.

[0046] The laser emitting device 101 may be a laser line projector, a laser rangefinder, or a laser level.
