Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Referring to Figures 1 and 2, a portable electronic scale includes a housing 1, a measuring circuit board disposed in the housing 1, and a sensor 2 electrically connected to the measuring circuit board, and the sensor 2 is connected to a load-bearing mechanism 3 , the housing 1 is provided with a sensor fixing mechanism 4, the sensor fixing mechanism 4 includes a cable-stayed block 41 fixed in an "S" shape in the housing 1, and one end of the sensor 2 is fixed on the cable-stayed block 41 , the other end of which is fixed to the bearing mechanism 3; the sensor fixing mechanism 4 also includes a reinforcement block 42 for reinforcing the connection between the housing 1 and the cable-stayed block 41. The sensor 2 is directly fixed on the housing 1, which reduces the number of connectors, effectively avoids shaking that may occur during the connection process, and saves costs.

Wherein, the portable electronic scale further includes a handle ring 5 connected with the housing 1 , and the handle ring 5 and the housing 1 are integrally formed.
