The invention relates to a front and back adjusting structure of a furniture hinge, which comprises a base connected with a furniture main body and a hinge cup seat arranged on a furniture door body. Adjusting cover plates are glidingly sleeved in front and back on the base and hinged with the hinge cup seat through a supporting arm, two insides of the adjusting cover plates are provided with protrusions or two sides are inwards provided with inner turnover edges, a front sliding groove and a back sliding groove are formed between the protrusions or the inner turnover edges and the inner top surfaces of the adjusting cover plates and connected with the base through a front adjusting convex nail and a back adjusting convex nail, two sides of the base corresponding to the front sliding groove and the back sliding groove are provided with outer turnover edges, and the front sliding groove and the back sliding groove of the adjusting cover plates slide forward and backward along the outer turnover edges by adjusting the front adjusting convex nail and the back adjusting convex nail. The inside of the adjusting cover plates are matched and glidingly connected with the outer turnover edges outside the base through the front sliding groove and the back sliding groove between the protrusions or the inner turnover edges and the top surfaces of the adjusting cover plates, so the adjusting structure has firm structure, simultaneously has the function of limiting up and down, and avoids long-term use and release due to abrasion at the riveted joint between the front and back adjusting convex nails and the base. The adjusting structure has the advantages of simple and reasonable structure, convenient installation, easy production, and long service life.

The invention discloses an oven with a uniform heating function. The oven comprises a shell, wherein the bottom of an inner cavity of the shell is fixedly connected with an oven body, both sides of the top of the inner cavity of the oven body are provided with first through holes respectively, both sides of the inner wall of the oven body are provided with second through holes respectively, the top of the inner wall of the shell is fixedly connected with a first sliding column, and both sides of the bottom of the first sliding column are fixedly connected with fixing plates respectively. According to the oven, through the arrangement and cooperation of the first sliding column, a bearing, a first turntable, first pull rods, first sliding blocks, first movable columns, first heating bodies,a motor, a second turntable, a connecting column, second pull rods, second sliding blocks, second movable columns, second heating bodies, second sliding columns and a controller, when the oven is used, the function of uniformly heating food can be achieved, the situation that the food is wasted since the food cannot be uniformly heated is avoided, the effect that the food can be uniformly heatedis ensured, and the oven is suitable for application and popularization.

The invention discloses an overlay film dual-layer stent capable of being orderly and completely degraded, and belongs to the technical field of medical apparatuses. The overlay film dual-layer stentcomprises an outer layer naked stent and an inner layer overlay film stent, wherein the stent part adopts biodegradable metal and alloy thereof or biodegradable high molecular materials, the expansionmanner is saccule expansion; an overlay film adopts biodegradable high molecular materials; the outer layer naked stent is released in advance, and can firstly pass through a lesion narrow section; the position and the length of the inner layer overlay film stent can be decided according to the situation of an aneurism neck and the situation of an interlayer aneurism cut; when being released, theinner layer overlay film stent is pressed in and fixed on the outer layer naked stent, so that the aneurism which is near an important collateral blood vessel can be treated; and after the aneurism is subjected to thrombosis and is contracted to a nature condition, the overlay film dual-layer stent is sequentially degraded according to the below sequence: degrading the overlay film, degrading theinner layer stent, degrading the outer layer naked stent, and finally performing complete degrading, so that the situation that foreign matters exist in vitro for a long time is avoided, and the situation that a person takes anti-thrombotic medicines for a long term is avoided.
