[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-3 This embodiment provides the following technical solution: a fuse quick winding device, including a clamp 1 and a rotator 2. The clamp 1 is detachably connected to the rotating rod 201. The clamp 1 and the rotator 2 work together to form the fuse winding structure. By using the clamp 1 and the rotator 2, the two ends of the fuse can be fixed, and the fuse can be rotated to perform the winding operation. This replaces the manual winding operation of the fuse by twisting it, avoiding wear and tear on the hands and improving the winding efficiency and quality of the fuse.

[0028] The clamp 1 includes a hinge shaft 101, a clamping plate 102, and an elastic element 103. The clamping plate 102 is rotatably connected to both the front and rear sides of the hinge shaft 101. The left end of the clamping plate 102 is the clamping end, and the right end of the clamping plate 102 is the driving end. The elastic element 103 is disposed between the driving ends of the clamping plates 102 on both the front and rear sides. The front and rear ends of the elastic element 103 pass through the strip groove 104 provided on the clamping plate 102 and are engaged in the positioning groove 105 provided on the clamping plate 102. Through the hinge shaft 101, the clamping plate 102, and the elastic element 103, when the driving end of the clamping plate 102 is manually pressed, the clamping ends of the clamping plate 102 can move away from or closer to each other, thereby completing the clamping and fixing of the fuse.

[0029] In some embodiments, the elastic element 103 is an elastic metal strip. One end of the elastic metal strip passes through the strip groove 104 on the front clamping piece 102 and is inserted into the positioning groove 105 on the front clamping piece 102. The other end of the elastic metal strip passes through the strip groove 104 on the rear clamping piece 102 and is inserted into the positioning groove 105 on the rear clamping piece 102.

[0030] The rotator 2 includes a rotating rod 201 and a driving device. The left end of the rotating rod 201 is provided with a clamping groove 202 adapted to the elastic element 103, and the rotating rod 201 is provided with a first positioning hole that penetrates the clamping groove 202. A first positioning bolt 203 is threaded into the first positioning hole. The other end of the rotating rod 201 is connected to the driving device. Through the clamping groove 202 and the first positioning bolt 203, the elastic element 103 can be clamped onto the rotating rod 201 and fixed onto the rotating rod 201. Thus, under the drive of the driving device, the rotating rod 201 can rotate with the clamp 1, thereby twisting the fuse and performing a winding operation on the fuse.

[0031] When the fuse is de-energized, the drive device includes a first handle 204, which has a drive unit inside. One end of the drive unit is connected to a first cutter head 205, and the other end of the first cutter head 205 extends through to the outside of the first handle 204 and is rotatably connected to the first handle 204. The first cutter head 205 is detachably connected to the rotating rod 201. The first handle 204, the drive unit, and the first cutter head 205 can drive the rotating rod 201 to rotate.

[0032] The rotating rod 201 is provided with a first slot 207 for the first cutter head 205 to be inserted. The rotating rod 201 is provided with a second positioning hole that passes through the first slot 207. A second positioning bolt 206 is threaded into the second positioning hole. The rotating rod 201 can be installed on or off the first cutter head 205 by means of the second positioning bolt 206.

[0033] In some embodiments, the drive unit may consist of a drive motor, a gear reducer and a transmission shaft. The output shaft of the drive motor is connected to the input end of the gear reducer, the output end of the gear reducer is connected to one end of the transmission shaft, and the other end of the transmission shaft is connected to the first cutter head 205. Thus, under the opening and closing action of the drive switch, the drive motor is activated, thereby causing the first cutter head 205 to drive the rotating rod 201 to rotate.

[0034] Example 2

[0035] Please see Figure 4-6When winding the fuse while it is energized, the rotary actuator 2 should be manually driven to avoid sparks between the electric actuator and the energized fuse, which could pose a safety hazard. Therefore, the rotary actuator 2 should be manually driven to rotate.

[0036] The driving device may also include a second handle 208, one end of which is rotatably connected to a second blade head 209. The second blade head 209 is detachably connected to a rotating rod 201. The other end of the second handle 208 is rotatably connected to a turntable 210. The turntable 210 is rotatably connected to the second blade head 209 via a connecting shaft. A crank handle 211 is fixedly connected to the outside of the turntable 210. With the second handle 208, the second blade head 209, the turntable 210, the connecting shaft, and the crank handle 211, after clamping both ends of the fuse onto the holder 1, the crank handle 211 can be manually cranked to make the turntable 210 drive the connecting shaft, the second blade head 209, and the rotating rod 201 to rotate. This causes the rotating rod 201 to drive the holder 1 and the fuse to rotate, thus performing a winding operation on the fuse.

[0037] The rotating rod 201 is provided with a second slot 213 for the second cutter head 209 to be inserted. The rotating rod 201 is provided with a third positioning hole that passes through the second slot 213. A third positioning bolt 212 is threaded into the third positioning hole. The rotating rod 201 can be easily installed and removed from the second cutter head 209 by means of the third positioning bolt 212.

[0038] The working principle of this utility model is as follows: When in use, press the driving end of the clamping piece 102 to squeeze the elastic member 103. At this time, the clamping ends of the two clamping pieces 102 move away from each other. Then, place the two ends of the fuse between the clamping ends of the two clamping pieces 102. Then, release the clamping piece 102. Under the elastic action of the elastic member 103, the two ends of the fuse are clamped.

[0039] When the fuse is not energized, the rotating rod 201 is driven to rotate electrically. The rotating rod 201 is fixed to the first cutter head 205 by the second positioning bolt 206. Then, the switch on the first handle 204 is turned on, so that the drive unit drives the first cutter head 205 to rotate, thereby causing the rotating rod 201 to drive the clamping plate 102 to rotate, thus completing the wire winding operation of the fuse.

[0040] When the fuse is energized, the rotating rod 201 is driven to rotate manually. The rotating rod 201 is fixed to the second cutter head 209 by the third positioning bolt 212. Then, the crank handle 211 is turned so that the turntable 210 drives the connecting shaft and the second cutter head 209 to rotate. This causes the rotating rod 201 to drive the clamping plate 102 to rotate, thus completing the fuse winding operation.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
