Household sewing machines have many functions, which are usually embodied by accessory devices.
Some sewing machines do not have these attachments, which will not affect the correct sewing.
1. Operating table top Sewing machines will have an operating table. Industrial sewing machines and old-fashioned sewing machines have relatively large table tops. Household electric sewing machines have relatively small table tops, and some are equipped with large operating tables. The large console is easier to work, and the small console can also work normally.
2. The light bulb is for lighting during sewing. Many household electric sewing machines have a built-in light bulb together with the power switch to turn on the light when the machine is turned on. If there is no light bulb, it will not affect the work, or the effect of putting a desk lamp is the same.
3. Automatic needle threading device This device is only available on household electric sewing machines, which is convenient for people with bad eyesight to thread needles. But because of this device, the direction of the eye of the needle is forward and backward, and people with good eyes must also use the automatic needle-piercing device to pierce the needle. There are some defects in the design of the automatic needle threading device of some sewing machines, which makes the needle threading operation very difficult. There is no automatic needle threading device on industrial sewing machines and old-fashioned sewing machines. The eye of the needle is left and right, making it easy to thread the needle manually.
4. Buttonhole control lever Only available on household electric sewing machines, there is a difference between four-step buttonhole and one-step buttonhole. Relatively speaking, the control lever of the four-step keyhole is simple in design and easier to operate. The convenience of a one-step buttonhole is that you don't need to worry about it after starting the buttonhole, and it is completed in one time, but the design of the buttonhole lever is relatively incomplete. Old-fashioned sewing machines use the presser foot to complete the buttonhole, and there are no such accessories on the sewing machine. Industrial sewing machines have special buttonhole machines, and ordinary sewing machines do not have these accessories. When purchasing a sewing machine, these accessories do not need to be concerned, but one point should be noted: the accessories cannot interfere with normal operation. For example, some sewing machines have problems with the automatic needle threading design, which makes threading difficult, so consider giving up.
