Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] see figure 1 , the invention discloses a reciprocating cutting tool, in a preferred embodiment, the reciprocating cutting tool is a jigsaw. The jigsaw includes a motor housing 1 arranged horizontally, one end connected to the motor housing 1 , a reduction box 2 arranged vertically, and a support plate 3 located below the motor housing 1 for supporting. Wherein, a motor 11 is arranged in the motor housing 1 , and the motor shaft 12 of the motor 11 meshes with the reduction gear 21 arranged in the reduction box 2 and drives the reduction gear 21 to rotate. An eccentric shaft 22 is eccentrically connected to the reduction gear 21 , and the other end of the eccentric shaft 22 is matched with the reciprocating mechanism 4 vertically arranged in the reduction box 2 . The reciprocating mechanism 4 includes a reciprocating rod 5. Wh...

Abstract

The invention provides a reciprocating cutting tool, comprising a motor shell (1) and a reduction gearbox (2) connected with the motor shell (1), wherein a motor (11) is arranged in the motor shell (1); a reciprocating mechanism (4) is arranged in the reduction gearbox (2); the reciprocating mechanism (4) comprises a suspension (40) and a reciprocating rod (5) which is connected with the motor (11) through a reduction gear (21) and an eccentric shaft (22) and is driven by the motor (11); the suspension (40) comprises a top slab (41) and an underplate (42); the reciprocating rod (5) is only in movable connection with the underplate (42), and can not exceed the top plate (41) along the direction of reciprocating motion. The reciprocating rod can carry out guide-localization without depending on the top plate of the suspension, so the reciprocating rod can not extend out of the top plate of the suspension in a reciprocating moving process of the reciprocating rod so as to greatly reduce the vertical height of the reduction gearbox. Therefore, the vertical height of the reciprocating cutting tool is reduced, and the cutting tool is convenient for application.

Description

technical field [0001] The invention relates to a reciprocating cutting tool, in particular to a reciprocating mechanism of a jigsaw. Background technique [0002] A reciprocating mechanism of a jigsaw is disclosed in Japanese Patent JP454801. see image 3 , the reciprocating mechanism of the jigsaw is pivotally connected and arranged in the reduction box (not shown), which includes a suspension 400 that can pivot around a pivot shaft 440, and the suspension 400 includes a top plate 410, a bottom plate 420 and the side arm connecting the top plate 410 and the bottom plate 420, and the top plate 410 and the bottom plate 420 are respectively provided with through holes 430, 450 for guiding and positioning the reciprocating rod 50 arranged in the through holes 430, 450. A driving slider 460 is also connected to the reciprocating rod 50, and the driving slider 460 is located between the top plate 410 and the bottom plate 420 of the suspension 400. After being driven by the gear...
