Cohesion　and　friction　angle　are　important　indicators　of　shear　strength　in　mining　engineering.　Indoor　testing　methods　are　detached　from　the　actual　state　of　the　rock　mass　and　affected　by　disturbances　and　significant　dimensional　effects　that　do　not　fully　reflect　the　shear　strength　of　the　rock　mass　itself.　In　situ　borehole　shear　testing　is　of　great　practical　importance　because　of　its　low　disturbance　and　high　speed.　In　this　paper,　a　new　testing　device　based　on　the　principle　of　a　rock　borehole　shear　tester　was　designed　to　simulate　the　shear　test　in　the　laboratory.　Seven　shear　indenters　were　designed　to　test　the　effect　of　different　tooth　heights,　spacing,　and　angles　on　the　shear　strength　of　rock-like　specimens,　and　the　damage　surface　was　scanned　in　three　dimensions　and　compared　with　conventional　triaxial　tests　and　compression　shear　tests.　The　results　show　that　as　the　tooth　height　increases,　the　flatness　of　the　press-in　damage　surface　increases,　and　the　results　will　be　closer　to　the　press-shear　test.　As　the　spacing　increases,　the　maximum　damage　angle　and　the　damage　surface　between　the　grooves　gradually　decrease.　The　tooth　angle　has　little　effect　on　the　friction　angle,　but　cohesion　decreases　significantly　when　exceeds　60　degrees.
