[0033] 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 of 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.

[0034] Refer to Figure 1 、 Figure 3 and Figure 5, an embodiment provided by the present utility model: a stamping positioning mechanism for a metal fuse box, including a base 1, and a clamping mechanism 2 is provided on the inner wall of the top end of the base 1; the clamping mechanism 2 is used for positioning and clamping the metal fuse box. The clamping mechanism 2 includes a telescopic rod 201, a rotating plate 202 is rotatably connected to the outer wall of the telescopic rod 201, a connecting rod 203 is rotatably connected to the top end of the rotating plate 202. By rotating the rotating plate 202, the connecting rod 203 is driven to rotate. The left end of the connecting rod 203 is rotatably connected to a movable plate 204. The movement of the connecting rod 203 drives the corresponding movable plate 204 to move. A rotating plate 206 is rotatably connected to the inner wall of the top end of the base 1, and a connecting plate 205 is rotatably connected to the outer wall of the rotating plate 206. The rotating plate 206 and its connecting plate 205 can play a certain role in dust prevention. A movable rod 207 is fixedly connected to the outer wall of the connecting plate 205. The movable rod 207 plays a guiding role. The left end of the connecting plate 205 is rotatably connected to a slider 211, and the slider 211 can move vertically. A chute 208 is opened at the top end of the base 1. An inserting plate 210 is elastically connected to the inner wall of the movable plate 204 through a connecting spring 212. There are two groups of inserting plates 210, and they are L-shaped. A support and contraction mechanism 3 is provided at the bottom end of the telescopic rod 201, and the support and contraction mechanism 3 can contract and hide the clamping mechanism 2.

[0035] Referring to Figure 2 , Figure 4 and Figure 5 , the top end of the telescopic rod 201 is fixedly connected to the inner wall of the top end of the base 1. Through the base 1, a supporting force is provided for the telescopic rod 201. The outer wall of the movable plate 204 is slidably connected to the inner wall of the top end of the base 1. The movable plate 204 slides horizontally on the inner wall of the top end of the base 1. The left end of the slider 211 is slidably connected to the right end of the movable plate 204. The sliding between the two avoids movement interference. The outer wall of the movable rod 207 is slidably connected to the inner wall of the chute 208. The chute 208 is provided to guide the movable rod 207. One end of the connecting spring 212 is fixedly connected to the outer wall of the inserting plate 210, and the other end of the connecting spring 212 is fixedly connected to the inner wall of the movable plate 204. The outer wall of the inserting plate 210 is slidably connected to the inner wall of the movable plate 204. Due to the elasticity of the connecting spring 212, the inserting plate 210 has a reset and limiting function. And only the inner wall of the left movable plate 204 is provided with the connecting spring 212 and the inserting plate 210. An inserting hole 209 is opened at the top end of the base 1. The outer wall of the inserting plate 210 is inserted into the inner wall of the inserting hole 209. There are multiple groups of inserting holes 209. The multiple groups of settings can thus adapt to different metal fuse boxes.

[0036] Referring to Figure 1 and Figure 5, the support contraction mechanism 3 includes a bottom plate 301. A moving plate 304 is fixedly connected to the front end of the bottom plate 301. The movement of the bottom plate 301 is driven by the moving plate 304. A set of connecting plates 302 are rotatably connected to both the left and right sides of the bottom plate 301. A moving block 303 is rotatably connected to the bottom end of the connecting plate 302. The movement of the bottom plate 301 drives the rotation of the connecting plate 302, causing the moving block 303 to move. A fixing plate 306 is fixedly connected to the front end of the base 1. A bolt 305 is threadedly connected to the inner wall of the fixing plate 306. The fixing plate 306 and its bolt 305 play a limiting role. The top end of the bottom plate 301 is fixedly connected to the bottom end of the telescopic rod 201. The telescopic rod 201 consists of two sets of sleeves, and its overall length can change. The outer wall of the moving plate 304 slides on the inner wall of the front end of the base 1. The outer wall of the moving block 303 is slidably connected to the inner wall of the bottom end of the base 1. When the moving plate 304 moves downward, the two moving blocks 303 move apart. The right end of the bolt 305 is threadedly connected to the left end of the moving plate 304, and their threaded connection achieves a fixing effect.

[0037] Working principle: When relevant personnel need to perform stamping positioning on the metal fuse box, pinch the two plugging plates 210, and then move the left movable plate 204 to the right. When the movable plate 204 moves, it will drive the corresponding connecting rod 203 to rotate. At this time, the rotating plate 202 will rotate and drive the other three connecting rods 203 to rotate, causing the other three movable plates 204 to move towards the middle to clamp and position the metal fuse box. At the same time, when the movable plate 204 moves, it will drive the connecting plate 205 and the rotating plate 206 to rotate to a certain extent. The movable rod 207 moves along the chute 208. When the movable plate 204 does not move, the rotating plate 206 and the connecting plate 205 are stretched, so as to prevent dust from falling into the inner wall of the base 1.

[0038] When the clamping mechanism 2 is not in use, rotate the bolt 305 to release the limit between the bolt 305 and the moving plate 304, and then the moving plate 304 can be moved downward, causing the moving plate 304 to drive the bottom plate 301 to move downward. Further, the two connecting plates 302 will open, and the clamping mechanism 2 will move downward. When the protrusions on both sides of the top end of the movable plate 204 are clamped with the top end of the base 1, rotate the lowermost bolt 305 at this time, and then the lowermost bolt 305 is fixed to the moving plate 304, so as to achieve the purpose of storing the clamping mechanism 2.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
