The utility model discloses a magnetic instrument rack, solving the problems of enabling both hands of a worker performing manual operations to be freed and saving the labor power. The magnetic instrument rack comprises an L-shaped support (1). An instrument (10) is arranged on a transverse plate of the L-shaped support (1). Elastic sleeves (3) are bound between a vertical plate of the L-shaped support (1) and the instrument (10). Grooves (9) are arranged in the vertical plate of the L-shaped support (1). A through hole (8) is arranged in each of the grooves (9). A steel ball (5) is movably arranged in each of the grooves (9), and one end of a connecting rod (4) is fixedly connected with the steel ball (5) while the other end of the connecting rod (4) penetrates through the corresponding through hole (8) and then fixedly connected with a magnetic sucking disc (2). A cover plate (6) is arranged on each groove (9). The cover plates (6) and the vertical plate of the L-shaped support (1) are riveted together through rivets (7).
