[0002] In the prior art, the pole chain saw generally fixes the pole directly to the main handle of the chain saw, and then the chain saw is connected to an external power supply. After the power is turned on, the pole is used to cut high-level branches. It is impossible to adjust the high position of multiple chain saws, and the pole and chain The disassembly and assembly of the saw is very inconvenient, resulting in low efficiency for the operator; in addition, the integrated setting of the rod and the chain saw makes it inconvenient to cut low branches, and the operator is troublesome to use. After the saw is integrated, it is very troublesome to set the anti-self-locking switch on the handle of the rod, which consumes a lot of materials
[0003] In addition, when the rod and the chain saw are electrically connected by plugging and unplugging, if the rod is not used, the connection will be charged, which will easily cause injury to the operator; and if the power switch of the chain saw is exposed, when the operator turns on the rod The power plug, if the operator touches the power switch of the chain saw, it will easily cause harm to the operator

Embodiment Construction
[0021] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0022] Such as Figure 1-2 As shown, a pole chain saw includes a pole 1 and a chain saw 2. The chain saw housing 3 is equipped with a double switch 4, a chain saw main switch 5, a motor 6 and a chain saw power plug 7. The pole 1 is equipped with A micro switch 8, a pole main switch 9 and a pole power plug 10 are provided. The chainsaw power plug 7 and the pole power plug 10 are electrically connected to the motor 6 through the double switch 4, and the chain saw power plug is selected through the double switch 4. 7 is electrically connected with the motor 6 or the selection lever power supply plug 10 is connected with the mo...

A rod chain saw comprises a rod (1) and a chain saw (2). A two-wire switch (4), a chain saw main switch (5), a motor (6), and a chain saw power plug (7) are arranged in a chain saw shell (3). The rod (1) is provided with a microswitch (8), a rod main switch (9), and a rod power plug (10). The chain saw power plug (7) and the rod power plug (10) are in electrical connection with the motor (6) through the two-wire switch (4). The electrical connection of the chain saw power plug (7) and the motor (6) or the electrical connection of the rod power plug (10) and the motor (6) can be selected through the two-wire switch (4). The joint of the chain saw and the rod is ensured non-voltage in the case of using the chain saw. When the rod and the chain saw are combined for using, the chain saw power plug is ensured non-voltage so as to protect the operator from being damaged.
Description
technical field [0001] The invention relates to a pole chain saw, in particular to a dual power supply switching device for the pole chain saw. Background technique [0002] In the prior art, the pole chain saw generally fixes the pole directly to the main handle of the chain saw, and then the chain saw is connected to an external power supply. After the power is turned on, the pole is used to cut high-level branches. It is impossible to adjust the high position of multiple chain saws, and the pole and chain The disassembly and assembly of the saw is very inconvenient, resulting in low efficiency for the operator; in addition, the integrated setting of the rod and the chain saw makes it inconvenient to cut low branches, and the operator is troublesome to use. After the saw is integrated, it is very troublesome to set the anti-self-locking switch on the handle of the rod, and consumes a large amount of materials. [0003] In addition, when the rod and the chain saw are elect...
