[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 - Figure 3 As an embodiment provided by the present utility model: A fixing tool for producing small household appliance transformers includes a base 1 for supporting the overall device. A winding machine 2 for driving the coil frame to rotate is installed at the top of the base 1. The winding machine 2 is a prior art and can start working by connecting to the power supply. Due to the prior art, this case will not be described in detail. A support assembly 3 for supporting the support block 4 is installed at the right end of the output shaft of the winding machine 2. The support assembly 3 includes a support shaft 31 for supporting the overall support assembly 3. The left end of the support shaft 31 is fixedly connected to the right end of the output shaft of the winding machine 2. By starting the winding machine 2, the support shaft 31 can be driven to rotate. A support block 4 for fixing the coil frame is sleeved on the outer wall of the support shaft 31. The support block 4 is made of rubber material, has the ability of elastic deformation, and the outer wall is relatively rough. The coil frame can be fixed by sleeving it on the outer wall. The right end of the support shaft 31 is fixedly connected with a sealing plate 36 for closing the opening at the right end of the support shaft 31. A connecting rod 38 for driving the extrusion block 33 to move penetrates and is slidably connected to the right end of the sealing plate 36.

[0031] Refer to Figure 1 - Figure 3, the support assembly 3 further includes a push block 37 for driving the connecting rod 38 to move. The left end of the push block 37 is fixedly connected to the right end of the connecting rod 38. When the push block 37 moves left and right, it will drive the connecting rod 38 to move synchronously. A buckle 310 for fixing the push block 37 is fixedly connected to the right end of the support shaft 31. The buckle 310 is made of plastic and will undergo elastic deformation when being squeezed. A chute 311 for accommodating the buckle 310 is provided at the right end of the push block 37. The buckle 310 and the chute 311 are adapted to each other. After the buckle 310 is inserted into the inside of the chute 311, the push block 37 will be fixed and unable to move. An unlocking assembly 5 for driving the buckle 310 to disengage from the chute 311 is provided at the right end of the support assembly 3. The unlocking assembly 5 includes a slider 53 for squeezing the buckle 310. The slider 53 is slidably connected to the right end of the chute 311. The slider 53 can slide back and forth inside the chute 311. A hinge rod 52 for driving the slider 53 to move outward is hinged to the right end of the slider 53. A pressing block 51 for driving the hinge rod 52 to move is hinged to the left end of the hinge rod 52. The pressing block 51 is slidably connected to the right end of the push block 37. By pressing the pressing block 51, the hinge rod 52 can be driven to move downward, and the hinge rod 52 pushes the slider 53 to force it to move outward.

[0032] Referring to Figure 2 - Figure 4 , the support assembly 3 further includes a clamping block 32 for fixing the fixing sleeve 312. The clamping block 32 is slidably connected to the inner wall of the support shaft 31. A slope is provided at the right end of the clamping block 32. When the slope is squeezed, the clamping block 32 will be forced to move outward. An extrusion block 33 for squeezing the clamping block 32 is fixedly connected to the left end of the connecting rod 38. The extrusion block 33 and the clamping block 32 are adapted to each other. A slope is provided at the left end of the extrusion block 33. A fixing sleeve 312 for fixing the support block 4 is fixedly connected to the right end of the support block 4. A clamping groove 313 for accommodating the clamping block 32 is provided on the inner wall of the fixing sleeve 312. The clamping groove 313 and the clamping block 32 are adapted to each other. After the clamping block 32 is inserted into the inside of the clamping groove 313, the fixing sleeve 312 will be fixed and unable to move. A support plate 34 for driving the clamping block 32 to move is fixedly connected to the left end of the clamping block 32. An unlocking spring 35 for pushing the support plate 34 inward is fixedly connected to the front end of the support plate 34. The front end of the unlocking spring 35 is fixedly connected to the inner wall of the support shaft 31. The unlocking spring 35 will always push the support plate 34 inward. A reset spring 39 for pushing the push block 37 is fixedly connected to the right end of the closing plate 36. The right end of the reset spring 39 is fixedly connected to the left end of the push block 37. The reset spring 39 will always push the push block 37 outward.

[0033] Working principle: When the support block 4 needs to be replaced, the pressing block 51 can be pressed downward first to move it downward. The downward movement of the pressing block 51 will squeeze the hinge rod 52 to rotate and move it downward. The downward movement and rotation of the hinge rod 52 will squeeze the slider 53 to force it to move outward. The outward movement of the slider 53 will squeeze the buckle 310 to disengage it from the inside of the slide groove 311. At this time, the push block 37 will no longer be fixed, and the reset spring 39 will push the push block 37 outward to move it outward. The push block 37 will drive the connecting rod 38 and the extrusion block 33 to move outward synchronously. Since the extrusion block 33 no longer squeezes the card block 32, the unlocking spring 35 can push the support plate 34 to drive the card block 32 to move inward and out of the inside of the card slot 313. At this time, the fixing sleeve 312 will no longer be fixed, and the operator can remove the support block 4 and the fixing sleeve 312.

[0034] When a new support block 4 needs to be installed, the newly replaced support block 4 can be sleeved on the outer wall of the support shaft 31, and the slot 313 can be aligned with the block 32. Then the push block 37 can be pushed backward to drive the extrusion block 33 to squeeze the block 32 so that it moves outward and is inserted into the slot 313. In this way, the support block 4 and the fixing sleeve 312 will be fixed, and the buckle 310 will also be inserted into the inside of the slide groove 311 to re-fix the push block 37. In this way, the support block 4 is installed.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
