A pivoting device for a cooking equipment which includes a lower housing and an upper housing that can be opened and closed relative to each other, said pivoting device comprising: a first body (2, 2') configured to be mounted on one of the upper and lower housings (11, 12); a second body configured to be mounted on the other one of the upper and lower housings (11, 12), said second body being pivoted to said first body (2, 2') and being rotatable about a pivoting axis; and a limiting unit connected to and movable along with said second body for limiting a pivoting angle of said second body relative to said first body (2, 2'); said first body (2, 2') including a first radial stop surface (231, 231'), a second radial stop surface (233, 233') staggered with said first radial stop surface (231, 231') along a direction parallel to the pivoting axis,and a guide wall surface (235, 235') connected to said first and second radial stop surfaces (231, 231', 233, 233'); and said limiting unit including a limiting member, said limiting member being movable relative to said first body (2, 2') between a first limiting state, where said limiting member is rotatable along with said second body in a circumferential direction of the pivoting axis and is limited by said first radial stop surface (231, 231'), and a second limiting state, where said limiting member is rotatable along with said second body in the circumferential direction of the pivoting axis, moves along said guide wall surface (235, 235') toward said second radial stop surface (233, 233'), and is limited by said second radial stop surface (233, 233'), characterized in that said first body (2, 2') further includes a third radial stop surface (232, 232') spaced apart from said first radial stop surface (231, 231') in a circumferential direction of the pivoting axis, and a fourth radial stop surface (234, 234') spaced apart from said second radial stop surface (233, 233') in the circumferential direction. a first body (2, 2') configured to be mounted on one of the upper and lower housings (11, 12); a second body configured to be mounted on the other one of the upper and lower housings (11, 12), said second body being pivoted to said first body (2, 2') and being rotatable about a pivoting axis; and a limiting unit connected to and movable along with said second body for limiting a pivoting angle of said second body relative to said first body (2, 2'); said first body (2, 2') including a first radial stop surface (231, 231'), a second radial stop surface (233, 233') staggered with said first radial stop surface (231, 231') along a direction parallel to the pivoting axis,and a guide wall surface (235, 235') connected to said first and second radial stop surfaces (231, 231', 233, 233'); and said limiting unit including a limiting member, said limiting member being movable relative to said first body (2, 2') between a first limiting state, where said limiting member is rotatable along with said second body in a circumferential direction of the pivoting axis and is limited by said first radial stop surface (231, 231'), and a second limiting state, where said limiting member is rotatable along with said second body in the circumferential direction of the pivoting axis, moves along said guide wall surface (235, 235') toward said second radial stop surface (233, 233'), and is limited by said second radial stop surface (233, 233'), characterized in that said first body (2, 2') further includes a third radial stop surface (232, 232') spaced apart from said first radial stop surface (231, 231') in a circumferential direction of the pivoting axis, and a fourth radial stop surface (234, 234') spaced apart from said second radial stop surface (233, 233') in the circumferential direction.
