Description

Flatcar convenient to change syringe needle Technical Field The invention relates to the technical field of textile technology, in particular to a flatcar convenient for replacing a needle. Background The flat car convenient for replacing the needle head is a flat car device which can be convenient for replacing the needle head. The flat bed is also called a flat bed sewing machine, and is generally called a single needle flat bed sewing machine, which mainly uses a sewing thread to form a stitch on a sewing material, so that one or more layers of sewing materials are interwoven or sewn together, the flat bed is the most basic type of sewing machine in sewing equipment, and the sewn stitch is tidy and attractive, uniform, flat and firm, high in sewing speed and simple and convenient to operate. However, the existing flatcar has the following defects when the needle is replaced: 1. Firstly, a screw driver or other tools are needed to be used for unscrewing a bolt for fixing the needle, then the needle to be replaced is moved downwards to be taken down, a new needle is inserted, and after the insertion is completed, the bolt is screwed down again by the corresponding tools, so that the needle is fixed and replaced; 2. In actual operation, if the damaged needle head is to be replaced, or the needles with different types are to be replaced according to different materials, the steps of unscrewing the bolts are inconvenient to operate, other tools are needed, the damaged needle head cannot be directly replaced, the complexity of the operation steps is increased, or the progress of processing is affected because auxiliary tools cannot be found in time. In view of the above, the present document proposes a flatcar that facilitates replacement of needles. Disclosure of Invention The invention provides a flat car convenient for replacing a needle, which solves the defects that in the prior art, a screw driver is needed to be used firstly or other tools are needed to be used for unscrewing a bolt for fixing the needle, then the needle to be replaced is moved downwards to be taken down, a new needle is inserted, and after the insertion is finished, the bolt is screwed down again by the corresponding tools, so that the needle is fixed to be replaced, in actual operation, if the damaged needle is needed to be replaced, or needles with different types are needed to be replaced according to different materials, the steps are needed to be repeated, the operation of unscrewing the bolt is inconvenient, and the replacement can not be directly carried out by the aid of other tools, so that the complexity of the operation steps is increased, or the processing progress is influenced because auxiliary tools can not be found in time.
