[0016] A multifunctional switch is disposed in the lower housing, abuts against the bottom end of the small silicone button, presses the pressing part onto the upper cover, and is connected to the MCU;

[0017] A watch strap assembly is installed on the back side of the lower housing through two watch strap installation grooves.

[0018] Furthermore, the strap assembly includes:

[0019] A male buckle for a watch strap, mounted on the back of the lower housing through one of the watch strap mounting grooves;

[0020] A female watchband buckle is installed on the back of the lower housing through another watchband mounting groove and matches with the male watchband buckle.

[0021] The advantages of the utility model are:

[0022] 1. A large key groove and a small key groove are provided on the upper cover, an extension part is provided outwardly on both sides of the large silicone key, and each extension part is provided with a locking hole. The large silicone key is provided in the large key groove and is locked on the upper cover through the two locking holes, and the key plate abuts against the bottom end of the large silicone key. Since the key plate and the upper cover press the large silicone key, combined with the locking of the extension part, the large silicone key will not fall off even if the key plate is pressed by the large silicone key for a long time; and a pressing part is provided outwardly on the side of the small silicone key, the small silicone key is installed in the small key groove, and the multi-function switch abuts against the bottom end of the small silicone key, and the pressing part is pressed on the upper cover, so that the small silicone key will not fall off even if the multi-function switch is pressed by the small silicone key for a long time, that is, the stability of the installation of the large silicone key and the small silicone key is improved by providing the extension part and the pressing part, thereby greatly improving the durability of the counter.

[0023] 2. A charging port is set on the side of the lower shell, a Type-C interface is installed in the charging port, a lithium battery is set between the lower shell and the upper cover, and the lithium battery is connected to the MCU and the Type-C interface respectively; that is, the lithium battery supplies power to the entire counter through the MCU. When the lithium battery is used up, the lithium battery can be charged in time through the Type-C interface. The Type-C interface is a mainstream and universal interface. Most electronic products use the Type-C interface. You can easily find a Type-C charging cable for charging. There is no need to purchase additional button batteries of the same specifications for replacement as traditionally, which greatly improves the convenience of charging the counter.

[0024] 3. By setting up a conductive strip to connect the MCU and the keypad, instead of traditional welding wires or socket strips, it not only effectively reduces the cost of the counter, but also is easy to install. It can achieve connections at different angles between the MCU and the keypad, and the keypad can be pressed and fixed by the conductive strip, effectively improving the stability of the counter.

[0025] 4. By setting the light-transmitting window of the LED light array display screen and the upper cover as one piece, the overall sealing performance is effectively improved, and the durability of the counter is further improved. BRIEF DESCRIPTION OF THE DRAWINGS
