[0024] Example
[0025] Please see Figures 1-6 This application provides a technical solution: a lucky cat with a swing arm that is easy to change, including a lucky cat body 110, a swing arm 130, a side cover 140, an outer cover 160, and a hand cranking mechanism 150. The lucky cat body 110 has a slot 120. One end of the outer cover 160 is fixed to the side surface of the swing arm 130. The side cover 140 is fixed to the lucky cat body 110. The outer cover 160 is rotatably mounted on the side cover 140. The outer cover 160 is fixedly sleeved on the swing frame 154.
[0026] A hand-cranking mechanism 150 is installed inside the lucky cat body 110. A frame 151 is fitted into a slot 120. The hand-cranking mechanism 150 enables the swing arm 130 to swing. The hand-cranking mechanism 150 includes a frame 151, a circuit board 152, an electromagnet 153, a swing frame 154, and a magnet 157. The frame 151 is fitted into the slot 120. The circuit board 152 is fixed inside the frame 151. The electromagnet 153 is mounted on the circuit board 152. The swing frame 154 is fitted onto the frame 151 and is rotatably mounted on the frame 151. The magnet 157 is fixed on the swing frame 154. The magnets 157 and 153 repel each other. An outer sleeve 160 is fixedly fitted onto the swing frame 154. The circuit board 152 and 153 are electrically connected together. The circuit board 152 and 153 are powered by a rechargeable battery.
[0027] The frame 151 has an irregularly shaped hole 155, and the swing arm 154 is engaged in the irregularly shaped hole 155. The irregularly shaped hole 155 limits the swing angle of the swing arm 154 while also allowing the swing arm 154 to be engaged in a designated position on the frame 151. It also includes a counterweight 156, which is fixed to one end of the swing arm 154. The counterweight 156 ensures that the swing arm 130 swings more smoothly. Finally, it includes a limiting cover 158, which is fixed to... On the upper surface of the frame 151, the limiting cover 158 is set to restrict the swing frame 154 within the frame 151. It also includes a limiting plate 159, the upper end of which is fixed to the swing frame 154. The limiting plate 159 allows the swing frame 154 to be quickly positioned and assembled onto the frame 151. The lucky cat body 110 has two slots 120, which are symmetrically arranged. The arrangement of the two slots 120 facilitates the changing of the position of the frame 151.
[0028] Specifically, the working principle of this easily interchangeable swing arm lucky cat is as follows: In use, the swing frame 154 is snapped onto the frame 151, then the limiting cover 158 is installed onto the frame 151, and the frame 151 is snapped into the slot 120. Next, the side cover 140 is installed onto the lucky cat body 110 and fitted onto the swing frame 154. Finally, the outer sleeve 160 on the swing arm 130 is fixedly fitted onto the swing frame 154, while the outer sleeve 160 is inserted into the side cover 140. When the switch is turned on, the rechargeable battery powers the circuit board 152 and the electromagnet 153. Due to the magnetic repulsion between the electromagnet 153 and the magnet 157, the magnet 157 is repelled by the electromagnet 153. Then, under the action of the counterweight 156, the magnet 157 falls back. The interaction of the magnet 157, the electromagnet 153, and the counterweight 156... The swing arm 130 swings back and forth under the combined action of the irregular hole 155 and the swing frame 154. The setting of the irregular hole 155 and the swing frame 154 limits the swing amplitude of the swing arm 130. When it is necessary to change the swing arm, turn off the switch, remove the current swing arm 130, remove the two side covers 140, and take the frame 151 out of the slot 120, thus removing the hand crank mechanism 150. Then rotate the frame 151 180 degrees and install it into another slot 120. Then follow the above steps to put the side cover 140 back onto the lucky cat body 110, install the swing arm 130 onto the swing frame 154, and finally change the position of the non-swinging swing arm 130 as needed. Turn on the switch to make the swing arm 130 swing. This swing arm is easy to change and the swing arm 130 is easy to change. It is highly applicable and brings a better user experience.
