The invention provides a tensile strength tester for a frozen ice body on a surface of a material, belongs to the technical field of cold region and low-temperature engineering, and is applied to measuring the tensile strengths of a frozen ice body on different materials. A lifting table is arranged between a test bed and an operating platform, is in contact with a steel tube through a bearing and slides on the steel tube up and down; a lead screw is connected with the lifting table through the test bed; a force sensor is fixed at the lower end of the lifting table; the operating platform is fixed on a base and is in parallel to the base; a mold is positioned on a to-be-tested material, the upper end of the mold is connected with the force sensor through a connection device, and the to-be-tested material is fixed on the operating platform. The tensile strength tester for the frozen ice body on a surface of the material can measure the tensile bond strength of the frozen ice body on the surface of any material, and can also obtain the tensile bond strengths of the frozen ice body at different loading rates.
