Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
[0014] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0015] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

The motor spindle 2 passes through the motor housing 1, and the motor spindle 2 is connected to a baffle 4. The baffle 4 is arranged on the top of the motor housing 1. The adjustable limit assembly 3 is arranged on the motor housing 1.

The card plate 34 is rotatably connected, and the limit paddle 32 can be rotated and switched between a first state and a second state. In the first state, the limit paddle 32 limits the baffle 4 so that the motor shaft 2 cannot be completely separated from the motor housing 1. In the second state, the limit paddle 32 releases the limit on the baffle 4 so that the motor shaft 2 can move freely along the axial direction and thus separate from the motor housing 1. The design of the adjustable limit component 3 makes the refueling operation more convenient and quick. It is only necessary to toggle the limit paddle 32 to switch between the two states. Refueling can be performed without disassembling the motor, which significantly improves the refueling efficiency. When the motor is working, the limit component prevents the baffle 4 from being completely separated from the motor housing 1, thereby ensuring the stable operation of the motor and avoiding failures caused by separation. The optimized motor design helps to improve the production capacity and efficiency of the production line and meet the cotton spinning industry's demand for high-efficiency production.
