Before, I thought of making the needle bar of the traditional needle short and letting it hang the needle bar directly for use.
Later, it was found that it was more reasonable to use the needle clamping bar.
This rationality does not mean that the working state is more reasonable, but that the traditional needle is used and more reasonable. When the needle rod is short, it is no longer a traditional long needle, it becomes a new needle type, and the needle adapted to it must be re-manufactured.
Transmission structure of the machine: slider cam
The battery compartment is designed for quick release. Remove to install the RCA interface.
The orientation of the screen can be turned at will.
At the top is a button and a charging port.
Plus the length of the battery compartment: 118mm
Length with RCA interface: 80mm. Holding the handle, the machine is basically in the palm of your hand.
