Claim Text:
1. A digital angle finder, comprising: a hollow housing, having a rectangular cross section; a power supply assembly, insertably arranged at a first end of the hollow housing; a digital display screen assembly, arranged on the hollow housing and electrically connected with the power supply assembly; and an angle checking assembly, movably arranged at a second end of the hollow housing opposite to the first end, the angle checking assembly including a contacting surface, an elastic sleeve, and a variable resistor member, the variable resistor member is disposed inside the elastic sleeve, the elastic sleeve is electrically connecting with the digital display screen assembly and the power supply assembly and also movably arranged between the second end of the hollow housing and the contacting surface, and the contacting surface is contacting an angle-checking object; wherein the hollow housing is positioned on a work surface and the contacting surface is checking and inclined based on an angle of the angle-checking object, the variable resistor member is changing the resistance and then the resistance is transmitting to the digital display screen assembly for transferring an angle value and showing the angle value.
