This invention relates to a cultivation device and method for the protection of rare plants, belonging to the field of plant cultivation technology. It includes multiple ground support rods laid horizontally on the ground along the direction of plant growth inclination; multiple connecting rods positioned between adjacent ground support rods along their length; and multiple anchoring nails fixed to the underside of each ground support rod along its length. The support rods are positioned between the ground support and the plant trunk, and an elastic traction element is vertically positioned between the support rods and the ground support. This invention uses the interconnected ground support rods and connecting rods to form a ground support, which is then fixed in the soil using anchoring nails. The elastic traction element applies a downward pulling force to the support rods, causing them to exert a force on the plant trunk opposite to its inclination direction, thus straightening the tilted plant trunk. The reaction force of the plant trunk on the support rods presses the ground support downward, preventing root damage during the straightening process.

The utility model discloses a tool for compressing and welding stator and rotor punching sheets, which comprises a base, a die core and a buffer device, the die core is arranged on the base, the buffer device comprises a first lower pressing plate, a second lower pressing plate and a spring, the first lower pressing plate is positioned below the second lower pressing plate, the first lower pressing plate is sleeved on the outer side of the die core, the second lower pressing plate is positioned above the die core, and the spring is arranged on the die core. The inner diameter of the second lower pressing plate is smaller than the outer diameter of the mold core, and the spring is located between the first lower pressing plate and the second lower pressing plate. When an external force punches downwards, the second lower pressing plate acts downwards on the spring, and then the acting force is conducted to the first lower pressing plate through the spring, so that the stator or rotor punching sheet is pressed downwards; by arranging the springs, downward punching force can be buffered, the situation that acting force acting on the stator punching sheet or the rotor punching sheet is too large is avoided, the stator punching sheet or the rotor punching sheet is effectively prevented from being excessively pressed, the stator punching sheet or the rotor punching sheet is protected, and therefore the quality of the stator obtained through final welding can be improved.
