[0022] The following is a detailed description of the specific settings and functions of this embodiment. When replacing the brush head, press the two squeezing rods 16 to squeeze inward. During the process, the spring 15 will be compressed, and the side sliding rod 17 will also move to the other end of the side slide 12. At this time, the side sliding rod 17 will cancel the limit of the two sets of limit rods 19. Without the limit of the side slide 12, the user can directly remove the card plate 18 and the structure below, which is convenient for the user to replace. When installing, press the two squeezing rods 16 to squeeze inward, and the spring 15 will be driven to compress during the process. The side sliding rod 17 is retracted and moved to the other end of the side slide groove 12. At this time, the limiting rods 19 at both ends of the card plate 18 equipped with other types of brush head structures can be aligned with the two ends of the card block 11, so that it is stuck in the middle of the card groove 191 until the end of the limiting rod 19 is fixed under the fixed plate 1. At this time, the squeezing rod 16 is released, and the spring 15 will drive the squeezing rod 16 to recover. During the process, the side sliding rod 17 can be stuck at the end of the limiting rod 19 and then limit the brush head structure below, which is convenient for replacing brush heads of different types and has higher applicability.

[0023] Example 2, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, slots 20 are provided on both sides of the middle of the lower end of the block 11, and plug blocks 21 are fixedly installed on both sides of the middle of the upper end of the card plate 18. The plug blocks 21 are plugged into the slots 20, and a card slot 191 is formed between the middle of each two limit rods 19.

At this time, the side sliding rod 17 will cancel the limit of the two sets of limit rods 19. Without the limit of the side slide 12, the user can directly remove the card plate 18 and the structure below, which is convenient for the user to replace. When installing, press the two squeezing rods 16 inward, which will drive the spring 15 to compress and the side sliding rod 17 to move to the other end of the side slide 12. At this time, the brush head structure of other models can be installed The limiting rods 19 at both ends of the card plate 18 are aligned with the two ends of the card block 11, so that it is stuck in the middle of the card slot 191 until the end of the limiting rod 19 is fixed below the fixed plate 1. At this time, the extrusion rod 16 is released, and the spring 15 will drive the extrusion rod 16 to recover. During the process, the side sliding rod 17 can be stuck at the end of the limiting rod 19 and then limit the brush head structure below, which is convenient for replacing different types of brush heads and has higher applicability. The slot 20 below the card block 11 matches and plugs into the plug block 21 above the spring 15, which can play a guiding and indicating role when the operator replaces different types of brush heads, making it convenient for the user to install different brush heads.

[0025] The method of use and working principle of this device: when replacing the brush head, press the two extrusion rods 16 to squeeze inwards. During the process, the spring 15 will be compressed and the side slide rod 17 will also move to the other end of the side slide groove 12. At this time, the side slide rod 17 will cancel the limit of the two sets of limit rods 19. Without the limit of the side slide groove 12, the user can directly remove the card plate 18 and the structure below it, which is convenient for the user to replace. When installing, press the two extrusion rods 16 to squeeze inwards. During the process, the spring 15 will be compressed and the side slide rod 17 will move to the other end of the side slide groove 12. At this time, the two ends of the card plate 18 equipped with other types of brush head structures can be removed. The end limit rod 19 is aligned with the two ends of the card block 11, wherein the slot 20 below the card block 11 matches and plugs into the plug block 21 above the spring 15, which can play a guiding and indicating role when the operator replaces brush heads of different types, making it convenient for the user to install different brush heads so that it is stuck in the middle of the card slot 191 until the end of the limit rod 19 is fixed under the fixed plate 1. At this time, the extrusion rod 16 is released, and the spring 15 will drive the extrusion rod 16 to recover. During the process, the side sliding rod 17 can be stuck in the end of the limit rod 19 and then limit the brush head structure below. By setting a quick-release structure, it is convenient for users to replace brush heads of different types, and it has higher applicability.
