The invention provides a vertebral body resetter, which comprises a head, a main body and a tail. The head includes a hinge structure comprising at least two sets of hinges, each set of hinges comprising at least four interconnected hinge pieces. During the distraction process of the vertebral body reducer, the head functions as a skeleton, which is spontaneously arranged to form an arc and is stereoscopically distracted in all directions. The umbrella-shaped head design of the present invention can cause the vertebral body to be stretched in the sagittal and coronal directions, and a negative pressure cavity is formed in the horizontal direction to accommodate the bone fragments protruding into the spinal canal and relieve the compressive damage to the spinal nerve. The umbrella-shaped space can effectively increase the contact area and better integrate with bone cement or bone graft materials, thereby reducing the risk of broken nails and rods after surgery.

The orthopedic nail remover of the present invention realizes precise drilling and real-time monitoring during the drilling process, avoids the deviation between the drill bit and the broken nail, realizes drilling through the traction device and avoids chiseling of the surrounding bone; the invention can safely The broken nail can be effectively removed without causing great loss to the bone, and the difficulty of removing the nail can be reduced.

A portable vehicle stop tire breaker solves the problems that an existing tire breaker is complex in structure, relatively poor in stability and poor in tire breaking effect and can hurt a person mistakenly. The portable vehicle stop tire breaker is characterized in that at least one module base is installed in an aluminum alloy combined base; each module base is provided with tire breaking nails and a protective cover; rolling locating end covers are installed on the left side and the right side of the combined base; the thickness is in normal distribution from the top wall of the protective cover to the side walls of the protective cover; the protective cover is connected with protective cover buckle installation clamping grooves of each module base through protective cover buckles folded inwards flatly; and symmetric oval holes are formed in the rolling locating end covers. The portable vehicle stop tire breaker has the beneficial effects that the aluminum alloy combined base is of a cavity structure, the strength is high, the bottom face is provided with serrated strips, the adhesive force between the bottom face and the ground is improved, the tire breaker falls to the ground and grabs the ground more stably, the perpendicularity and stability of the tire breaking nails can be better guaranteed, the tire breaking nails are prevented from laterally falling, it can be guaranteed that the human body is not harmed due to the wall thickness of the top wall of the protective cover, and the tire breaker can be more conveniently and rapidly grabbed and placed by a user through the arrangement of the rolling locating end covers.

The invention discloses an extrusion line type foam recovery plant which comprises a high-pressure water tank, a blow-off pipe pressing box, a discharging nozzle, an extrusion trough, an extrusion motor, a screw rod, a breaking motor, a breaking shaft, a breaking disc and breaking nails. A bottom frame is arranged on the lower portion of the high-pressure water tank, and a blow-off pipe is arranged at the bottom of the high-pressure water tank and provided with a first solenoid valve. A water inlet pipe is arranged on the right side of the high-pressure water tank and provided with a second solenoid valve. The breaking disc is arranged at the lower end of the breaking shaft, and the breaking nails are arranged on the upper portion of the breaking disc. Feeding holes are formed in the breaking disc. The discharging nozzle is formed in the right side of the extrusion trough and is in a conical barrel shape. The size of a foam plate can be reduced through breaking and heating, heating is even, transporting is convenient, and transport cost can be greatly reduced; and meanwhile the foam recovery plant is simple in structure and convenient to use and operate.

The invention discloses a safety explosion-proof tire puncturer, which comprises a nailing cavity, and a net nailing device is arranged in the nailing cavity, and the device includes left and right symmetrical nailing net modules, and a net rolling cylinder is arranged between the nailing net modules , the net roll is wrapped with a catch net, and the above catch net is provided with a thorn plate, and a series of tire-breaking nails are arranged in the said catching net, and the net ring at the bottom of each tire-breaking nail is connected with the thorn plate. The above-mentioned catch net is connected, and the front wheel of the vehicle triggers the trigger block and the rear wheel is nailed through the leverage of the lever, and the tire is deflated through the broken tire nail head and the deflation chamber of the net nail device, and the catch net wraps around the tire to limit the power, a two-pronged approach To ensure the control of the vehicle, the rotation of the rope reel is limited by the anti-winding spring and the anti-rolling module, and the threaded shaft of the splitting rope controls the splitting module to separate the two strands of rope, which can not only pull the vehicle smoothly to prevent the vehicle from escaping.

The invention discloses a broken hollow nail take-out device for the orthopedic department. The broken hollow nail take-out device comprises a device body, the device body is provided with a main rod,a first mounting side rod and a second mounting side rod are fixedly installed at the same side of the main rod from top to bottom respectively, a connection rod is movably connected to the first mounting side rod, a clamping head is welded to the bottom of the connection rod, a punching nail is detachably connected to the second mounting side rod, a clamping groove is formed in the surface of the top of the punching nail, the clamping head is matched with the clamping groove, and a nail take-out nail mounting part is arranged at the lower end of the main rod. Through the working mode of mutual cooperation of dual nails, the problems in the prior art that a nail breaking fracture face is unsmooth, and cannot be fixed and rotated are solved; the punching nail is provided with a conical nail head, the nail head is provided with a thread used for removing un-smoothness of the fracture face, the head of a nail take-out nail achieves maximal threaded combination for the plane, the cooperation of the main rod and the side rods makes the main rod and the side rods more convenient to control and use, the structures are optimized, and the operating difficulty is lowered.

The invention relates to a device for performing fast and effective separation and purification on turbid circulating water of steel rolling, which belongs to the technical field of steel-rolling sewage treatment equipment and is used for performing fast and effective water-pollution separation on the turbid circulating water of steel rolling.
