Abstract
trata-se de um conjunto de gaveta de cisalhamento para uso em uma pilha de bop. o conjunto de gaveta de cisalhamento inclui um bloco de gaveta disposto dentro do alojamento de gaveta de cisalhamento e que tem uma extremidade de avanço voltada para o furo, sendo que o bloco de gaveta é móvel entre uma posição aberta, em que o bloco de gaveta é retraído para longe do furo, e uma posição fechada, em que o bloco de gaveta é estendido em direção ao furo. a lâmina tem uma superfície de avanço, uma superfície posterior, uma borda de cisalhamento inferior, e uma borda superior, sendo que a lâmina é fixada à face de avanço do bloco de gaveta por fixadores que se estendem em um ângulo em relação a uma superfície superior do bloco de gaveta através de uma porção do bloco de gaveta e para o interior da superfície posterior da lâmina, sendo que a superfície posterior da lâmina é angulada de modo que seja perpendicular ao eixo geométrico longitudinal dos fixadores.
