[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] See also Figure 1-4A sewing machine that is easy to use includes a main body component 1; the main body component 1 includes a base 11, a mounting plate 12 is arranged on the top of the main body component 1; a needle 13 is arranged on the mounting plate 12; a connecting plate 14 is inserted into the inside of the base 11 and the inside of the mounting plate 12; a disassembly component 2 is symmetrically arranged on the connecting plate 14, and each group of the disassembly components 2 includes: a slide groove 21, which is opened on the outer wall of the connecting plate 14; a pull plate 22, which is slidably connected to the inside of the slide groove 21 and inserted into the inside of the connecting plate 14; a rotating plate 23, which is hinged to the outer wall of the pull plate 22 and is symmetrically arranged Two; a push plate 24, each of the outer side walls of the rotating plate 23 is hinged with a push plate 24; a limit block 25, each of the outer side walls of the push plate 24 is fixedly connected to the limit block 25, and each of the limit blocks 25 is slidably connected to the inner side wall of the connecting plate 14; a spring 26, arranged on the pull plate 22, and the two ends are respectively fixedly connected to the outer side wall of the pull plate 22 and the inner side wall of the connecting plate 14; a telescopic rod 5 is arranged on the pull plate 22, and the two ends of the telescopic rod 5 are respectively fixedly connected to the outer side wall of the pull plate 22 and the inner side wall of the connecting plate 14; each of the limit blocks 25 is provided with an inclined surface.

[0029] When ready to use, the operator places materials such as cloth strips on the base 11, and then the operator turns on the driving device in the mounting plate 12 to drive the needle to sew the cloth strips. When the sewing machine needs to be moved, the operator pulls the pull plates 22 on both sides respectively to make the pull plates 22 slide in the slide groove 21 and drive the rotating plate 23 to rotate. The rotating plate 23 rotates and drives the push plate 24 to move toward the inside of the connecting plate 14, so that the push plate 24 pulls the limit block 25 to completely enter the inside of the connecting plate 14, thereby removing the mounting plate 12 and the base 11, thereby facilitating the movement of the sewing machine. When it is needed to use, the operator pulls the pull plate 22 again, and the pull plate 22 drives the limit block 25 to move while stretching the spring 26. Then the operator inserts the connecting plate 14 into the mounting plate 12 and the base 11 by hand, and then releases the pull plate 22. Under the action of the spring 26, the spring 26 pulls the pull plate 22 is pulled back, thereby driving the limit block 25 to be inserted into the limit groove inside the mounting plate 12 and the base 11 to complete the installation. The operation process is relatively convenient, thereby improving the installation efficiency of the device; a telescopic rod 5 is arranged on the pull plate 22, and the telescopic rod 5 can limit the moving direction of the pull plate 22 to prevent the pull plate 22 from being deflected by the spring 26 when being pulled by the spring 26, thereby being stuck in the slide groove 21, causing the device to be unable to be used normally, thereby improving the stability of the device; each limit block 25 is provided with an inclined surface, so that when the operator inserts the connecting plate 14 into the mounting plate 12 and the base 11, the mounting plate 12 and the base 11 squeeze the limit block 25 on the same side, so that the limit block 25 is automatically forced to enter the connecting plate 14, and after the insertion is completed, it is automatically bounced into the limit groove by the spring 26, so that the operator does not need to pull the pull plate 22 during installation, thereby improving the convenience of the device.

[0030] Embodiment 2

[0031] See also Figure 1-4 , based on the first embodiment, a linkage function is added;

[0032] A linkage assembly 3 is provided on the connecting plate 14, and the linkage assembly 3 includes: a rotating rod 31, which is inserted into the connecting plate 14 and is rotatably connected to the connecting plate 14; a plate body 32, which is fixedly connected to the outer wall of the rotating rod 31; a rope body 33, each of the pulling plates 22 is provided with a rope body 33, and both ends of each of the rope bodies 33 are respectively fixedly connected to the outer wall of the pulling plate 22 and the outer wall of the rotating rod 31; the outer wall of the connecting plate 14 is fixedly connected to a fixing plate 6, and the plate body 32 is clamped and fixed to the fixing plate 6; the outer wall of the connecting plate 14 is hinged with a protective shell 4.

[0033] When the device is disassembled, the operator rotates the plate body 32 so that the plate body 32 drives the rotating rod 31 to rotate at the same time, so that the rope body 33 is wrapped around the rotating rod 31, so that the rope body 33 pulls the pull plate 22 to move at the same time, so that the operator only needs to rotate the plate body 32 to simultaneously disassemble the mounting plate 12 and the base 11, without pulling the two pull plates 22 separately, thereby improving the operator's work efficiency; the outer wall of the connecting plate 14 is fixedly connected to the fixing plate 6, and the operator rotates the plate body 32 until it is clamped and fixed with the fixing plate 6, so that when the operator disassembles the mounting plate 12 and the base 11, there is no need to use one hand to prevent the rotating rod 31 from rotating, and use one hand to disassemble the mounting plate 12 and the base 11, thereby improving the convenience of the device; the outer wall of the connecting plate 14 is hinged with a protective shell 4, and the protective shell 4 can completely cover the protruding structure on the connecting plate 14 to prevent the operator from accidentally touching it during use, resulting in unstable fixation of the device.
