Problems solved by technology

[0003] But there are many defects in this hand-held saw. First of all, in order to ensure its work efficiency, its power device is generally a relatively large internal combustion engine or electric motor, so that its entire volume and weight are basically only suitable for strong adult men to operate, and its work The noise will be particularly loud; and it generally needs to use diesel oil or engine oil during use, which is not environmentally friendly and is easy to dirty the machine itself and the operator; in addition, these hand-held saws cannot be applied to certain working environments, such as For some fruit trees or wood gardens with dense branches, the traditional hand-held saw may damage the nearby branches when used, resulting in economic losses such as fruit drop

Embodiment 1

[0030] refer to figure 1 As shown, the present embodiment provides a portable reciprocating saw for cutting high branches, including a working part 2, and the working part 2 includes a permanent magnet non-inductive motor 201, and the output shaft of the permanent magnet non-inductive motor 201 is connected with a long bar through a transmission mechanism 202. The shape saw blade 203, the transmission mechanism 202 is used to utilize the power output by the permanent magnet non-induction motor 201 to drive the saw blade 203 to perform axial linear reciprocating motion;

[0031] Such as figure 2 As shown, the permanent magnet non-inductive motor 201 includes a housing, and the housing is provided with a permanent magnet rotor 207, a printed circuit board 208 and a bottom magnet 209. The printed circuit board 208 is electrically connected to the controller through a wire 4, and the printed circuit board 208 and the bottom magnet The magnet 209 is fixedly connected in the casin...

Embodiment 2

[0035] Such as Figure 8 As shown, the difference between embodiment 2 and embodiment 1 is:

[0036] One end of the casing is connected to a rod-shaped body 1 through a connector 206, and the other end of the body 1 is connected to a power supply part 3. The power supply part 3 includes a battery holder casing 301, which is provided with a rechargeable battery and A controller electrically connected to the battery, a control switch electrically connected to the controller is provided on the battery holder housing 301; a cavity is formed inside the body 1, and the cavity 1 is provided with a battery, a controller and a permanent magnet non-induction motor 201 wires 4 for electrical connection.

[0037] Such as Figure 9 , the body 1 includes a first rod 101 and a second rod 102, the first rod 101 can extend into the cavity of the second rod 102, the length of the first rod 101 is not greater than the length of the second rod 102, the second rod 102 The connection with the fi...

Abstract

The invention discloses a portable reciprocating saw used for high branch clipping. The portable reciprocating saw used for the high branch clipping comprises a rod-shaped body; a working part and a power supply part are respectively arranged at the two ends of the body; the working part is connected with a long-strip-shaped saw blade by a transmission mechanism and the transmission mechanism is used for driving the saw blade to do axial straight reciprocating motion by the power output by a permanent magnet inductionless motor; a cavity is formed in the body and a wire electrically connectedwith the power supply part and the permanent magnet inductionless motor is arranged in the cavity. According to the reciprocating saw, an electromotor is used as power, so that various problems duringuse of the saw which uses an internal combustion engine as a power source can be avoided; the body uses the structure of a rod with the cavity and each component is relatively lighter, so that even women or older people can relatively easily operate the whole equipment; the output direction of the motor is changed into the back and forth reciprocating motion similar to a manual saw by the transmission mechanism, so that the working range of the saw during use can be small, the nearby branches would not be affected during working and the economic loss can be avoided.

Description

technical field [0001] The invention relates to the fields of agricultural production and gardening machinery and equipment, in particular to an energy-saving, environment-friendly and easy-to-operate light-duty saw, in particular to a portable reciprocating saw for cutting high branches. Background technique [0002] A saw is a tool used to saw off or cut wood or other items that need to be processed. It generally consists of a saw blade and a saw body composed of irregularly arranged saw teeth. There are many kinds of saws. According to their main purposes, they can be divided into horizontal saws for sawing wood, vertical saws for sawing wood along the grain of wood, and digging saws, also known as wire saws, which are mainly used for sawing curved shapes; The size can be divided into coarse sawtooth suitable for sawing larger and thicker wood, medium sawtooth suitable for sawing wood of general size and thickness, and fine sawtooth suitable for more detailed sawing; acco...
