[0018] The utility model is described in detail below in combination with the drawings and examples. Embodiment

[0019] A kind of collapse anti -theft nut, such as Figure 1 And Figure 2As shown, including the collapse of the periphery 1 and the fastening sleeve 2 with threaded hole can be embedded wrench, collapse of the periphery 1 cross section of the outer edge of the hexagonal set, can be matched with wrench twist, fastening sleeve 2 is cylindrical set, the inner edge of the collapse of the periphery 1 and the outer wall of the fastening sleeve 2 is provided with a plurality of easy deformation connecting edge 3, the collapse of the periphery 1 is set so that the collapse of the anti-theft nut can be twisted by the wrench, so that the easy deformation connecting edge 3 can be connected, so that the collapse of the periphery 1 can drive the fastening sleeve 2 with threaded hole in the middle twist, so that the collapse of the anti-theft nut can be normally twisted and fixed, and then through the wrench and other tools, knock the surface of the collapse of the periphery 1, because the easy deformation connecting edge 3 is easy to deform, its support capacity is limited, through the knocking of the tool makes the easy deformation connecting edge 3 force deformation, so that the collapse of the periphery 1 produces the situation of inwards collapse, resulting in the collapse of the periphery 1 also deformation, eventually leading to the collapse of the periphery 1 deformation can not match the wrench, so as to avoid other personnel to use wrench easily twist the nut, play a certain anti-theft effect, and because of many circumstances, the anti-theft nut may not need to be twisted out for more than ten years, so the deformation of the collapse of the periphery 1 and the easy deformation connecting edge 3 can be ignored, only the fastening sleeve 2 can firmly fix the object, the whole nut structure design is simple, the cost is low, but can play a basic anti-theft effect, and there is a larger gap in the middle, can save material.

[0020] As shown in Figure 1 and Figure 2 , the collapse of the periphery 1, the fastening sleeve 2 and the easy deformation connecting edge 3 are made of brass, which is soft, easy to cut, polish and drill, etc. The processing technology not only reduces the production cost, but also makes the brass nut can be customized according to the needs, meet the requirements of various shapes and specifications, and is convenient for processing the collapse of the periphery 1, the fastening sleeve 2 and the easy deformation connecting edge 3, and makes use of the characteristics of the soft brass, so that the collapse of the periphery 1 and the easy deformation connecting edge 3 have the characteristics of easy deformation, which is convenient for deformation by knocking, and finally leads to the wrench can not be matched, plays an anti-theft effect, and the brass material has good corrosion resistance, can resist the corrosion of air, water and some weak acid, weak base and other media. This property makes the nut body can still maintain its performance in humid and corrosive environment, prolong the service life.

[0021] As shown in Figure 2 and Figure 3As shown, the easily deformed connecting ridge 3 is vertically arranged, the middle section of the easily deformed connecting ridge 3 is V-shaped, and the height of the easily deformed connecting ridge 3 is less than the height of the collapse peripheral 1 and the fastening sleeve 2. When the collapse peripheral 1 is hit, the force is transmitted to the easily deformed connecting ridge 3, and the middle section of the easily deformed connecting ridge 3 is V-shaped, so that once the two sides receive the impact force, it is easy to cause deformation. Therefore, this structure design makes the easily deformed connecting ridge 3 collapse and deform easily when the collapse peripheral 1 is hit, thereby avoiding the wrench to easily loosen the nut. The design that the height of the easily deformed connecting ridge 3 is less than the height of the collapse peripheral 1 and the fastening sleeve 2 reduces the height of the easily deformed connecting ridge 3, thereby reducing the bearing capacity of the easily deformed connecting ridge 3, and facilitating the deformation and collapse of the easily deformed connecting ridge 3.

[0022] As shown, Figure 2 The separation type supporting core 4 is made of plastic material and is used for being embedded between the collapse peripheral 1 and the fastening sleeve 2. A plurality of clamping grooves 5 for accommodating the easily deformed connecting ridge 3 are arranged on the separation type supporting core 4. When the nut is turned, the separation type supporting core 4 is embedded between the collapse peripheral 1 and the fastening sleeve 2, and the easily deformed connecting ridge 3 is clamped into the clamping groove 5. The separation type supporting core 4 can connect the collapse peripheral 1, the fastening sleeve 2 and the easily deformed connecting ridge 3 to form a whole with higher strength, so that the wrench can be tightened without damaging the structure of the collapse peripheral 1 and the easily deformed connecting ridge 3. Therefore, the collapse peripheral 1 and the easily deformed connecting ridge 3 can be designed to be thinner, so that the effect of easier collapse and deformation is achieved. The easily deformed connecting ridge 3 is arranged in a ring array between the fastening sleeve 2 and the collapse peripheral 1, and the clamping groove 5 is arranged in a ring array on the separation type supporting core 4. The ring array arrangement of the easily deformed connecting ridge 3 makes it easier for all the easily deformed connecting ridges 3 to be clamped into all the clamping grooves 5 when the separation type supporting core 4 is embedded between the collapse peripheral 1 and the fastening sleeve 2, thereby facilitating operation.
