The clamping mechanism comprises a second clamping plate, second fixing plates are fixedly connected to the two ends of the bottom of the second clamping plate, first special-shaped holes are formed in the two ends of the top of each second fixing plate, threaded sleeves are fixedly connected to the two ends of the top of each first fixing plate, threaded blocks are in threaded connection with the interiors of the threaded sleeves, first rotating grooves are formed in the tops of the threaded blocks, first connecting blocks are arranged in the first rotating grooves, first special-shaped blocks are fixedly connected to the top of the first connecting blocks, and the first special-shaped blocks are arranged in the first special-shaped holes and movably connected with the second fixing plates in a sleeving mode. The clamping device has the advantages that the problem that an existing clamping device is prone to unstable clamping or limbs of a patient are prone to being separated from clamping plates during clamping can be solved, and the patient can be effectively prevented from being injured by clamping, which facilitates smooth operation or treatment.

The invention discloses a sacrificial anode protection device for a truss-type double-tube horizontal metering separator, which comprises several trusses arranged in the lower tank body of the double-barrel horizontal metering separator, and the top of each truss is connected with an upper platform, The bottom is connected with the lower platform, and the upper part of the upper platform is evenly distributed with a number of elastic dynamic sealing contact systems that can be in close contact with the top of the inner wall of the lower tank of the double-tube horizontal metering separator. The roller system closely contacts the bottom of the inner wall of the lower tank of the double-barrel horizontal metering separator. The middle parts of several trusses are connected by a screw that can control the lifting of the truss. Several sacrificial anodes are fixed on the screw, and the sacrificial anodes correspond to the trusses one by one. , and the sacrificial anode is arranged on the inner side of the corresponding truss. When the invention is used, the protection current is evenly distributed, and the inside of the tank body can be completely covered, and at the same time, the replacement of the sacrificial anode is convenient.

The invention belongs to the field of preparation of heterogeneous materials, in particular to a device and method for casting heterogeneous metal rods. Alternately cast two or more molten metals in the centrifugal casting section to obtain tubular materials in which two or more metals are alternately arranged radially, and then fill the core of the casting by die-casting to obtain two or more Metal castings in which the metals are arranged alternately in the radial direction, the obtained metal castings are demolded and subjected to stress relief annealing treatment, and finally the heterogeneous metal rods in which the different metals are arranged in the radial direction are alternately obtained. The heterogeneous metal rods prepared by the present invention have the characteristics of heterogeneous materials, and various alloy layers respectively improve the strength and toughness of the matrix to meet the needs of practical applications; the present invention can prepare large-sized heterogeneous metal rods with microstructure design With flexibility and directivity, the distribution ratio of different microstructures is easy to control, the casting yield is higher, and the application range is wider.

The invention discloses a magneto-rheological polishing cutter which comprises a pipe body, a magneto-rheological polishing solution, a polishing head and a polishing ball. The polishing head and thepolishing ball both have magnetism. A communicating containing hole and storage hole are formed in the pipe body along the axis. The magneto-rheological polishing solution is arranged in the containing hole and the storage hole. The top of the containing hole communicates with the outside, and a pressing device is arranged at the top end of the containing hole. The polishing head is fixed to the bottom of the pipe body. A lower storage cavity is formed in the polishing head, and the bottom of the lower storage cavity communicates with the outside. An upper storage cavity is formed in the lowerportion of the pipe body and communicates with the storage hole. A containing cavity is formed by the upper storage cavity and the lower storage cavity. The polishing ball is arranged in the containing cavity and can freely rotate. An on-off spring is arranged in the storage hole and is ejected on the polishing ball. The magneto-rheological polishing cutter has the advantages that compared with traditional materials, the polishing precision of the magneto-rheological polishing cutter solution is finer, the while polishing radius can be quite small, and the cutter can adapt to complex environments.

The invention relates to an outsole (1) for sports shoes (2) comprising nock-type elements arranged in the front sole area (3) and heel area (4), said nock-type elements extending in a conically tapered manner fro the base (6) thereof to the contact surface (7). The aim of the invention is to improve said outsole, in order to enable improved contact of the feet when they are placed on the ground, even when the ground is moderately hard. This is achieved by reducing the height (hred) of at least one nock-type element (5') in the sole edge area (12) of the heel area (4) in relation to the average height (hnorm) of the other nock-type elements (5'') in said area.

The invention relates to a countercurrent double-loop cylinder dryer, which comprises a support, an inner cylinder, an outer cylinder, a driving device, a feeding device and a discharging device, and is characterized in that: a middle cylinder is arranged between the inner cylinder and the outer cylinder, and one end of the inner cylinder and one end of the middle cylinder are respectively provided with an annular seal plate; one end of the outer cylinder is provided with a seal plate, and the three cylinders constitutes a material layer and two flue gas heating units, i.e., an inner-layer flue and an outer-layer flue; and a plurality of reinforcing supporting columns are arranged among the three cylinders for connecting and positioning, and frying plates are uniformly arranged on the outer wall plate of the inner cylinder and the inner wall plate of the middle cylinder. The problems that the material and the flue gas flow from the same pipeline, and are fully mixed, so that the dried material is mixed with impurities and the production safety is possibly generated by ineffectively controlling sparks in the flue gas to be contacted with the material and the like in the traditional drum drying machine can be solved, the structural design is reasonable, the performance is stable, the process flow is smooth, the overheating time of a dry area is long, the thermal efficiency is high, the energy is saved and the consumption is reduced, the quality of the dried material is high, and the range of application is wide.

The invention relates to the field of a chemical coating, in particular to white-washed two-component water-based paint with a matt surface. The formula of the white-washed two-component water-based paint with the matt surface comprises a main agent and a curing agent, wherein the main agent comprises components in percentage by mass as follows: 50%-70% of a water-based acrylic polyol dispersion, 1%-10% of butyl cellosolve, 1%-5% of titanium dioxide, 0.5%-10% of a matting agent, 0.5%-4% of a functional assistant and 10%-30% of distilled water. The formula can improve the rigidity and chemical resistance of the two-component water-based paint with the matt surface, so that the two-component water-based paint can compare favorably with the traditional oil paint, and real high environmental-protection and high-performance requirements for the paint are met.
