Document Type and Number:
WIPO Patent Application WO/2020/119767
Kind Code:
A1
Abstract:
A reciprocating saw (100), comprising: a housing (11), where an accommodating space (112, 113) is formed; a motor (12), disposed in the accommodating space and comprising a winding (122) extending along a first straight direction (101); a first transmission wheel (132), disposed in the accommodating space and connected to the motor; and an input shaft (141), which is driven by the motor to carry out reciprocating motion forward and backward. The first transmission wheel is fixed in the accommodating space along a support shaft (131) extending along a second straight direction (102), and is driven by the motor to rotate about a second straight line; the winding comprises a first end (121a) and a second end (121b) along the first straight direction, a first plane (108) perpendicular to the first straight line and passing through a first end face (121c) of the first end is defined, and a second end (109) perpendicular to the first straight line and passing through a second end face (121d) of the second end is defined; the first plane is parallel with the second plane, and the winding is located between the first plane and the second plane; at least part of the support shaft is located between the first plane and the second plane. The space in the housing is fully used according to the structure above, and the size of the whole machine is reduced.
