The pyrotechnic composition laser comprises a light condensation cavity; a vibration exciter and a first protection tube are arranged in the light condensation cavity; a pyrotechnic composition column is arranged in the first protection tube; the pyrotechnic composition column is coated with a uniform energy-containing material layer; one end of the pyrotechnic composition column and one end of the first protection tube are fixed to the light condensation cavity through fixing devices; a trigger device is arranged at the other end of thefirst protection pipe; a firing pin for impacting the pyrotechnic composition column is arranged in the trigger device; the fixed end of the firing pin is connected to the inner wall of the trigger device through a spring; an inserting groove is formed in the fixed end; a trigger piece capable of being pulled out is arranged in the inserting groove; and the trigger piece penetrates through the trigger device. According to the technical schemes of the invention, chemical energy stored in pyrotechnic composition is utilized; the energy-containing material is deflagrated to serve as a pumping source, so that pumping energy density is large; the pumping source is easy to machine and form through a powdery viscous agent. Therefore, the laser of the invention has the advantages of large outputenergy, light weight, small size and convenience in integration.

Throwing and refloating device
InactiveCN106223891AEnsure synergyReduced pull resistanceBorehole/well accessoriesEngineeringDistributor
The invention provides a throwing and refloating device which comprises a main body of the throwing and refloating device, a connector and a claw mechanism connected between the main body of the throwing and refloating device and the connector, wherein the claw mechanism comprises an inner claw and an outer claw which are disposed inside and outside respectively; upper ends of the inner claw and the outer claw are in a hinged connection with the main body of the throwing and refloating device; lower ends of the inner claw and the outer claw are in a hinged connection with the connector; and two hinged points of the upper and lower ends of the inner claw and two hinged points of the upper and lower ends of the outer claw are located at four vertexes of a parallelogram. In comparison with a single-claw structure in the prior art, the device is characterized in that the double claws are disposed on the connector; the inner claw and the outer claw work together, and thus the connector is not deflected to the main body of the throwing and refloating device easily, so that a force bearing direction of a blocking device is consistent with a hole shift axis of a water distributor as much as possible, and lifting and pull resistance of the throwing and refloating device is reduced; and the four hinged points are located at the four vertexes of the parallelogram, and thus cooperative effects of the inner claw and the outer claw are ensured, so that joint effects brought by the inner claw and the outer claw to the connector can be ensured.

Spring type key
The invention relates to a spring type key. The key comprises a key frame and a key cap with a plurality of outer corners, wherein the key cap is embedded in an accommodating hole of the key frame; the key also comprises a plurality of strip-shaped elastic arms; each elastic arm comprises an inner fixing arm part, at least one outer movable arm part and at least one corner transition part for connecting the inner fixing arm part with the at least one outer movable arm part; each corner transition part corresponds to each outer corner; and each inner fixing arm part is positioned inside an edge on one side of the bottom of the key cap, and the corner transition part corresponding to the inner fixing arm part extends out of the edge and extends to an edge adjacent to the edge along the corresponding outer corner and is fixed on the key frame through the outer movable arm part. The spring type key has the advantages of lower cost and proper pressing force, and the elastic arms of the spring type key contribute to reducing thickness of the key.
