Detailed Description

The present invention will be described in further detail with reference to specific examples, which are provided for illustrative purposes only, and are not intended to be limiting, and the scope of the present invention should not be limited thereby.

A handle comprises

A handle portion 1;

the control and display unit 4 is used for inputting, setting, storing, converting and displaying the tensile force;

and the connecting part 3 is used for connecting the tension sensor with a load.

The control and display unit comprises a processor 8, and a display screen 9, a tension sensor 11, a key 10 and a power supply unit 7 which are respectively connected with the processor.

The processor is a 32-bit ARM processor.

The processor is of the type STM32F030K 6T.

The key is a film key.

The power supply unit is a battery, preferably a dry battery.

The tension sensor is a Wheatstone bridge type weighing force transducer.

The handle part is coated with a colloid material.

The connecting part is a hook part, such as a gourd ditch, and preferably a No. 6 gourd hook.

The protective housing, including casing 5 and cap 2, once only shaping respectively after casing and cap die sinking, system has battery hatch door 6 on the casing.
