Abstract

Official abstract text for this publication.

The reciprocating cutting blade apparatus includes: a pair of reciprocating cutting blades disposed to overlap one another in a thickness direction; a support member configured to reciprocably support the reciprocating cutting blades in a longitudinal direction; and an adjustment mechanism configured to adjust a gap between the reciprocating cutting blades on a lower surface side of the support member. The adjustment mechanism includes: a screw hole provided in the support member; an adjustment screw including an external thread configured to threadedly engage with the screw hole through long holes provided in the reciprocating cutting blades; and a nut configured to threadedly engage with the external thread protruding from an upper surface of the support member to fix the external thread to the support member. The external thread protruding from the upper surface of the support member includes an operated portion configured to be operated to turn the adjustment screw.

First claim

Opening claim text (preview).

The invention claimed is: 1. A reciprocating cutting blade apparatus comprising: a pair of reciprocating cutting blades disposed to overlap one another in a thickness direction; a support member configured to reciprocably support the reciprocating cutting blades in a longitudinal direction; and an adjustment mechanism configured to adjust a gap between the reciprocating cutting blades on a lower surface side of the support member, the adjustment mechanism including: a screw hole provided in the support member; an adjustment screw including an externally threaded portion that protrudes from the upper surface of the support member and that is configured to threadedly engage with the screw hole through long holes provided in the reciprocating cutting blades; and a nut configured to threadedly engage with the externally threaded portion of the adjustment screw protruding from an upper surface of the support member to fix the external thread to the support member, wherein the externally threaded portion protruding from the upper surface of the support member includes an operated portion configured to be operated to turn the adjustment screw, and wherein the operated portion is a slotted portion provided in a top portion of the externally threaded portion of the adjustment screw. 2. The reciprocating cutting blade apparatus according to claim 1 , further comprising a transmission case to which the support member is independently attached, wherein the reciprocating cutting blades can be removed from the support member remaining attached to the transmission case by removing the adjustment screw. 3. A reciprocating cutting blade apparatus comprising: a pair of reciprocating cutting blades disposed to overlap one another in a thickness direction; a support member configured to reciprocably support the reciprocating cutting blades in a longitudinal direction; and an adjustment mechanism configured to adjust a gap between the reciprocating cutting blades on a lower surface side of the support member; and a transmission case to which the support member is independently attached, wherein the adjustment mechanism includes: a screw hole provided in the support member; an adjustment screw including an externally threaded portion configured to protrude from an upper surface of the support member and threadedly engage with the screw hole through long holes provided in the reciprocating cutting blades; and a nut configured to threadedly engage with the externally threaded portion protruding from an upper surface of the support member to fix the external thread to the support member, wherein the external thread protruding from the upper surface of the support member includes an operated portion configured to be operated to turn the adjustment screw, and wherein the reciprocating cutting blades can be removed from the support member independently attached to the transmission case by removing the adjustment screw. 4. The reciprocating cutting blade apparatus according to claim 3 , wherein the operated portion is a slotted portion provided in a top portion of the externally threaded portion. 5. The reciprocating cutting blade apparatus according to claim 3 , wherein the operated portion is a hole provided in an upper end portion of the externally threaded portion.
