The invention aims to provide an automobile side step fixing structure. The strength of installing points of a side step can be improved significantly, collapse of the side step existing in the using process of a passenger is avoided, and the safety and the reliability of the side step are improved by a large margin. According to the automobile side step fixing structure, the side step is fixed on an automobile threshold through a fixing bracket, and the key is that the fixing bracket comprises a lower support plate, an upper fixing plate and a middle connecting plate; the support plate is in a horizontal state, and the support plate is fixedly connected with the side step erected on the upper portion of the support plate through bolts; the fixing plate is in an oblique state and located on the outer side of the automobile threshold, and the fixing plate is fixedly connected with the automobile threshold through bolts; the connecting plate is integratedly composed of a lower connecting plate and an upper connecting plate, an included angle between the upper connecting plate and the lower connecting plate and an included angle between the upper connecting plate and the fixing plate are both obtuse angles, and opening directions are opposite; and one sides, away from the side step, of the fixing plate and the upper connecting plate are attached to the automobile threshold.

The invention relates to a wool knitted fabric shape-remembering finishing agent. The finishing agent comprises a waterborne polyurethane composition and a crosslinking agent, wherein the content of the waterborne polyurethane composition in the finishing agent is 2-8%, and the content of the crosslinking agent is 1.5-3% of the content of the waterborne polyurethane composition. The effectiveness of the crosslinking agent lies in that the crosslinking reaction temperature of polyurethane is reduced to 90-110 DEG C. The invention also provides a preparation method and application of the wool knitted fabric shape-remembering finishing agent. The wool knitted fabric treated with the provided shape-remembering finishing agent can be washed by a machine and dried by stoving, is easy to maintain, can remember the original shape of the fabric, can reduce the conditions of folding and distorting and has favorable anti-pilling performance, length-deformed recovery performance, fold recovery performance and better hand feel.

The invention provides a manufacturing method of a continuous rolling production line roller bed blank. The manufacturing method comprises the following technological characteristics that (1) thick plate components of a roller bed are discharged in an embedded nesting discharge manner; (2) after bottom plates of a transmission side roller bed and an operation side roller bed are fixed back to back, assembly and welding of components are carried out, symmetrical weld seams of the transmission side roller bed and the operation side roller bed are welded at the same time during assembly and welding, and construction is carried out from the two end parts of the two roller beds to the middle parts; and (3) after assembly and welding of the transmission side roller bed and the operation side roller bed, integral annealing is carried out. According to the manufacturing method of the continuous rolling production line roller bed blank, deformation of the roller bed blank can be effectively reduced or avoided, the utilization rate of raw materials can be greatly increased, and manufacturing cost of a continuous rolling mill roller bed blank is reduced.

A three-dimensional memory and its manufacturing method. The three-dimensional memory includes: a storage unit and a logic control unit that are bonded to each other on the front, and the logic control unit is connected to a control circuit. It is characterized in that the second metal wire of the storage unit and the first The metal wires are respectively arranged on the upper and lower sides of the channel layer in the memory unit, and both the first metal wire and the second metal wire are electrically connected with the control circuit. By arranging the second metal wire and the first metal wire respectively on the upper and lower sides of the channel layer in the memory cell, by separately arranging the first metal wire and the second metal wire so that the distribution of the metal wire becomes balanced, reducing or The deformation of the storage unit is avoided; at the same time, the metal wiring is simplified by scattered arrangement of the first metal wire and the second metal wire, so that the layout of the connection circuit between the first metal wire and the second metal wire and the control circuit is relatively simple, and the connection is improved. Reliability, avoiding connection reliability problems in the prior art caused by complex layout and process problems.

The invention discloses a propeller arm connection assembly. Propeller arms are installed on a machine body of an aircraft. Each propeller arm comprises a propeller arm first segment and a propeller arm second segment. The propeller arm connection assembly comprises a first connecting base and a second connecting base fixedly connected with the first connecting base in a butting mode through electric connectors. The first connecting base is connected with the propeller arm first segments, and the second connecting base is connected with the propeller arm second segments. At least one of the first connecting base and the second connecting base is in non-fixed limiting connection with the corresponding propeller arm first segment or the corresponding propeller arm second segment. According to the propeller arm connection assembly, one connecting base can swing together with the other connecting base which joggles under the condition that the propeller arm segments provided with paddles joggle; deformation of the electric connectors is reduced or avoided; and therefore poor contact in the subsequent connection process is avoided, and stability and safety of the aircraft are greatly improved.

The present application belongs to the technical field of cooking utensils, and in particular relates to an oven. The oven in this application includes a stove top, a stove top bracket, a backboard, a hoarding and a connecting bracket. On both sides of the cooktop board and used to support the cooktop board, the front end of the enclosure is provided with a first installation hole and a second installation hole, the cooktop bracket is connected with the enclosure through the first installation hole and the second installation hole, and the enclosure The rear end of the board is connected to the backplane through a connecting bracket. According to the oven in the present application, the stress on the front and rear ends of the enclosure can be improved at the same time, effectively improving the overall force distribution of the enclosure, thereby preventing the overall deformation of the enclosure, thereby reducing or avoiding the deformation of the stovetop.
