Motor mounting panel 3 passes through support column 2 to be installed on base 1, and motor 4 fixed mounting is on motor mounting panel 3. A synchronous belt wheel 5 is fixedly connected on the motor output shaft of the motor 4. The base 1 is also provided with a driven synchronous pulley, and the synchronous pulley 5 is in transmission connection with the driven synchronous pulley through a synchronous belt 6.

The synchronous belts 6 on two sides between the synchronous belt wheel 5 and the driven synchronous belt wheel are fixedly connected with a sensor mounting plate 7 through toothed plates respectively. Each sensor mounting plate 7 is respectively mounted on a sliding part of a correspondingly arranged linear slide rail 8 through a screw, and a fixed part of the linear slide rail 8 is fixedly mounted on the base 1 through a slide rail mounting plate 9, so that the sensor mounting plates 7 can reciprocate relative to the base 1 through the linear slide rails 8.

Because the weight of the sensor mounting plates 7 and the parts mounted on the sensor mounting plates are supported by the linear slide rails 8, when the motor drives the synchronous belt wheel 5 to rotate in a reciprocating manner, the synchronous belt wheel 5 drives the synchronous belt 6 meshed with the synchronous belt wheel to move in a reciprocating manner, the synchronous belt 6 further provides driving force for the two sensor mounting plates 7 arranged on the linear slide rails 8, and the two sensor mounting plates 7 are actuated to respectively move in a reciprocating manner along opposite directions of the linear slide rails 8; namely, the hanging rod 12 at one side extends out of the base 1, and the hanging rod 12 at the other side retracts into the base 1; and weighing the waste liquid bag or the product bag according to actual needs.
