Abstract: Provided are a spiro-containing derivative, and a preparation method therefor and the use thereof. In particular, provided are a compound as shown in general formula (I), and a preparation method therefor, a pharmaceutical composition containing same, and the use thereof in the preparation of a drug for preventing and/or treating central nervous system diseases related to 5-hydroxytryptamine receptors and/or trace amine-related receptors and/or dopamine receptors in mammals.

Abstract: The present invention is a pet training pad comprising a first end of a first conductive wire and a first end of a second conductive wire connected to a main controlling device, while a second end of the first conductive wire and a second end of the second conductive wire remain open. When a pet goes onto the pet training pad, the pet's foot makes contact with the first conductive wire and the second conductive wire at the same time, establishing an electrical circuit via the pet's foot. The main controlling device detects that the electrical circuit and then sends an electric shock current to the first conductive wire, thereby shocking the pet which will guide the pet to form a habit of not going to the position where the pet training pad is located.

Abstract: A pet training pad includes at least three supporting rods, a middle rod, at least three first connecting rods and at least three second connecting rods. For each supporting rod, one end of it is configured to be supported on a supporting surface, the other end of it is configured to support a campfire assembly. One end of the middle rod is provided with a first pivot, and the other end of the middle rod is provided with a second pivot. For each first connecting rods, one end of it is pivotably connected to corresponding one of the at least three supporting rods, the other end of it is pivotably connected to the first pivot. For each second connecting rods, one end of it is pivotably connected to corresponding one of the at least three supporting rods, the other end of it is pivotably connected to the second pivot.
