[0057] As shown in Figure 5 and Figure 6As shown, in order to prevent the key body 113 from being activated by mistake and causing harm to the user, a light touch sensor (not shown) is arranged in the accommodating cavity of the second shell 120. The key body 113 can only activate the crushing assembly 400 after the light touch sensor is activated by being touched. Specifically, the light touch sensor is located directly below the ring groove 103. In order to be able to touch the light touch sensor, a connecting hole 122 is formed in the bottom surface of the ring groove 103 and communicates with the accommodating cavity. The second blocking piece 123 at the position of the connecting hole 122 is clamped with the connecting hole 122, and the second blocking piece 123 partially penetrates into the ring groove 103 through the connecting hole 122.
