DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The fixing structure for the plug-in and pull-out head of the beauty instrument handpiece disclosed in the embodiment of the present application is shown in FIG. Figure 1 and Figure 2 In this embodiment, one end of the plug head 1 is connected to a beauty instrument chassis (not shown in the figure), and the other end is connected to a cable, and the other end of the cable is connected to a hand tool 2. A cable protection shell 3 made of a corrugated tube is also connected between the hand tool 2 and the plug head 1. During use, current and data are transmitted through the cable and the plug head 1, so that the hand tool 2 is in direct contact with the human body to ensure its stability in use. Since the hand tool 2 needs to be connected to the beauty instrument chassis for water and electricity during use, a water nozzle 4 and a wiring terminal 5 are also provided in the plug head 1, and the water nozzle 4 and the wiring terminal 5 need to be replaced frequently.

[0033] Reference Figure 1 and Figure 2 In this embodiment, in order to facilitate the replacement of the faucet 4 and the wiring terminal 5, the beauty instrument handpiece 2 plug-in head 1 uses a fixing structure including a mounting plate 6, and a through hole 60 is provided on the mounting plate 6. The through hole 60 is located at four vertex corners, and a mounting bolt 61 is connected in the through hole 60. The mounting bolt 61 can be connected with the threaded hole in the plug-in head 1, so that the mounting plate 6 is located in the plug-in head 1 and is firmly connected; then a first mounting hole 7 adapted to the faucet 4 and a second mounting hole 8 adapted to the wiring terminal 5 are opened on the mounting plate 6, and the faucet 4 is connected to the first mounting hole 7 and the wiring terminal 5 is connected to the second mounting hole 8, so that the faucet 4 and the wiring terminal 5 can be connected to the mounting plate 6 together outside the plug-in head 1; then the mounting plate 6 is connected to the plug-in head 1 by the mounting bolt 61; the faucet 4 and the wiring terminal 5 are easy to assemble and disassemble, and the structure is reliable.

[0034] Reference Figure 2 and Figure 3In this embodiment, in order to further fix the faucet 4 and the wiring terminal 5 in the first mounting hole 7 and the second mounting hole 8 respectively, a first fastener and a second fastener are provided on the mounting plate 6. The first fastener is used to position the faucet 4 in the first mounting hole 7, and the second fastener is used to fix the wiring terminal 5 in the second mounting hole 8. Among them, the first fastener includes a fixing nut 70; first, when the faucet 4 is connected in the first mounting hole 7, one end of the faucet 4 is located in the plug head 1, and the other end is used to connect with the chassis. The fixing nut 70 is threadedly connected with the end of the faucet 4 located in the plug head 1, and by tightening the fixing nut 70, the fixing nut 70 is abutted against the mounting plate 6, thereby effectively fixing the faucet 4, which is convenient to install and has a stable structure.

[0035] Reference Figure 2 and Figure 3 In the present embodiment, since the fixing nut 70 is threadedly matched with the water nozzle 4, when the fixing nut 70 is screwed, in order to prevent the water nozzle 4 from rotating in the first mounting hole 7 and interfering with the tightening of the fixing nut 70, a polygonal limit block 71 is provided at one end of the water nozzle 4 connected to the chassis. The polygonal limit block 71 is preferably set to be hexagonal, and then a limit groove 72 is provided on one side of the first mounting hole 7 on the mounting plate 6, and the polygonal limit block 71 is inserted into the limit groove 72; thereby, under the action of the polygonal limit block 71, the water nozzle 4 is effectively limited, and the water nozzle 4 is reduced from rotating when the fixing nut 70 is screwed, which provides convenience for screwing the fixing nut 70.

[0036] Reference Figure 2 and Figure 4 In this embodiment, the second fastener includes a card block 80, which is arranged on the side wall of the wiring terminal 5. Then, a card slot 81 adapted to the card block 80 is opened on the inner wall of the second mounting hole 8. Finally, when the wiring terminal 5 is connected to the second mounting hole 8, the card block 80 is simultaneously inserted into the card slot 81, thereby effectively fixing the wiring terminal 5 in the second mounting hole 8, and the operation is convenient.

[0037] In order to further strengthen the connection of the terminal block 5, fastening blocks 82 are provided on the inner walls on both sides of the slot 81. The length direction of the fastening blocks 82 is consistent with the axial direction of the slot 81, and the fastening blocks 82 and the inner walls of the slot 81 form a right angle. Then, a fastening groove 83 adapted to the fastening block 82 is opened on the side wall of the block 80. When the block 80 is inserted into the slot 81, the fastening block 82 is located in the fastening groove 83, thereby further strengthening the connection stability of the terminal block 5 in the second mounting hole 8, and the structure is reliable.

[0038] Reference Figure 4In this embodiment, since the wiring terminal 5 and the second mounting hole 8 are mainly fixedly connected by a buckle structure, in order to further improve the convenience of connection, the card block 80 can be quickly connected and positioned; by providing a positioning hole 90 on the card block 80, and then a positioning block 91 is slidably connected in the positioning hole 90, and a positioning groove 92 adapted to the positioning block 91 is provided on the inner wall of the card slot 81, and a driving member is also provided on the card block 80, and the driving member is used to drive the positioning block 91 to slide out of the positioning hole 90 and be engaged in the positioning groove 92, so that when the card block 80 is inserted into the card slot 81, when the card block 80 is engaged in the positioning groove 92, it is determined that the card block 80 is inserted in place, and at this time, there is no need to continue to insert the card block 80, so the insertion of the card block 80 and the card slot 81 is convenient, and the structure is reliable.

[0039] Reference Figure 4 In this embodiment, the driving member includes a driving spring 93, one end of the driving spring 93 is fixedly connected to the inside of the positioning hole 90, and the other end is fixedly connected to the positioning block 91. The initial state of the driving spring 93 is in a stretched state, and then when the card block 80 begins to be inserted into the card slot 81, the positioning block 91 is pressed by the inner wall of the card slot 81 and is retracted in the positioning hole 90. At this time, the driving spring 93 is in a compressed state until the positioning block 91 is aligned with the positioning slot 92. The positioning block 91 is not pressed by the inner wall of the card slot 81. The driving spring 93 tends to make the positioning block 91 have a tendency to pop out of the positioning hole 90, and then effectively snap-fit ​​into the positioning slot 92, thereby realizing the positioning of the card block 80 and effectively improving the connection convenience of the terminal block 5.

[0040] The implementation principle of the fixing structure for the plug-in head of the beauty instrument handpiece in the embodiment of the present application is as follows: by connecting the water nozzle 4 to the first mounting hole 7, and then using the fixing nut 70 to fix the water nozzle 4, thereafter aligning the clamping block 80 with the clamping slot 81, and then inserting the clamping block 80 into the clamping slot 81, at this time, the wiring terminal 5 is connected to the second mounting hole 8, and the fastening block 82 is also inserted into the fastening slot 83 to further improve the connection stability of the wiring terminal 5, thereby connecting the water nozzle 4 and the wiring terminal 5 together to the mounting plate 6, and finally using the mounting bolt 61 to directly connect the mounting plate 6 to the plug-in head 1, which effectively improves the convenience of replacing and disassembling the water nozzle 4 and the wiring terminal 5.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
