Tool-Less Blade Clamping Apparatus for a Reciprocating Tool

Номер: US20130193653A1

Автор: Gary Sinclair, Gavin Wright, Marc Vincent Marini, Matthew Carr, Vance E. Roe

Принадлежит: ROBERT BOSCH GMBH, Robert Bosch Tool Corp

Several preferred embodiments are disclosed for a tool-less blade clamping apparatus for a reciprocating tool of the type which has a reciprocating plunger which has a tool attachment receiving slot for receiving a tool attachment of the type that has a shank portion. The clamping apparatus has an unclamped position and a clamped position. In the unclamped position, a tool attachment can be easily inserted and when it is in its clamped position, the tool attachment is securely retained. The preferred embodiments have at least one spring biasing the apparatus toward the clamped position, a releasable retaining mechanism for holding the apparatus in its unclamped position after being placed in that position. When the blade shank portion is inserted into the slot a predetermined distance, the shoulders of the shank portion release the retaining mechanism to move it to its clamped position. When a blade is to be removed, the clamping apparatus needs only to be moved to its unclamped position by manually rotating the outer sleeve or collar, and the blade is normally ejected from the mechanism by contact with the blade shoulders as it reaches its unclamped position.

The first drive gear is hinged with an end of a first connecting rod ( 61 ) in an upward eccentric manner, and the other end of the first connecting rod ( 61 ) is hinged with the first reciprocating lever ( 71 ). The jig saw further comprises a second drive gear linked with the motor output end ( 3 ). The second drive gear is hinged with an end of a second connecting rod ( 62 ) in an eccentric manner, and the other end of the second connecting rod ( 62 ) is hinged with a second reciprocating lever ( 72 ) that is fixed with a second saw blade ( 102 ). A linear limit mechanism that enables the first reciprocating lever ( 71 ) and the second reciprocating lever ( 72 ) to maintain a distance therebetween and be capable of linear motion is further disposed. The first saw blade ( 101 ) and the second saw blade ( 102 ) are respectively clamped on inner side surfaces close to each other at lower portions of the first reciprocating lever ( 71 ) and the second reciprocating lever ( 72 ). Directions of linear reciprocating motions of the first saw blade and the second saw blade are opposite. In the present invention, components are designed to be symmetrical, so that the jig saw runs stably, is easy to operate, and has high working efficiency.
