Abstract: Disclosed is an electric saw guide plate capable of recycling lubricating oil, comprising two outer guide plates and an oil guide plate connected between the two outer guide plates; outer edges of inner walls of the outer guide plates and a periphery of the oil guide plate form a guide plate groove for containing a saw chain, a plurality of oil inlets are formed in an upper end of the oil guide plate and a plurality of oil outlets are formed in a lower end of the oil guide plate, the oil inlets and the oil outlets are communicated through an oil guide channel, and the oil inlets and the oil outlets are communicated with the guide plate groove at the same time. According to the electric saw guide plate, the saw chain is lubricated, and meanwhile the recycling of the lubricating oil is also realized.

Abstract: A novel saw chain, including a plurality of transmission pieces, a plurality of rebound transmission pieces, a plurality of cutters, a plurality of connecting pieces, and a plurality of pin shafts. The product of the average pitch between every two adjacent pin shafts in the saw chain, the maximum height of the saw chain, and the maximum thickness of the saw chain is 150-275 mm3. According to the novel saw chain, the size of the saw chain is reduced, energy consumption of the saw chain is effectively reduced, and the standby time of a lithium battery or a gasoline engine is effectively prolonged.

Abstract: A high-efficiency saw chain, including a plurality of transmission pieces, a plurality of rebound transmission pieces, a plurality of cutters, a plurality of connecting pieces and a plurality of pin shafts. The product of the average pitch between two adjacent pin shafts in the saw chain, the maximum height of the saw chain and the maximum thickness of the saw chain is 406 to 450 mm3. The high-efficiency saw chain may reduce the volume of the saw chain, reduce the size of the saw chain, effectively reduce the energy consumption of the saw chain, and effectively prolong the battery life of a lithium battery or gasoline engine.

Abstract: An electric chain saw assembly comprises a saw chain and a guide plate, the saw chain is arranged around an edge of the guide plate, and the saw chain comprises transmission chain pieces and connecting pieces which are sequentially and rotatably connected end to end; a top end of the transmission chain piece is are provided with a tooth cutting structure; and the tooth cutting structure comprises a cutting edge and a limiting tooth, the limiting tooth is located at a front end of the saw chain in a forward direction, the cutting edge is located at a rear end of the saw chain in the forward direction, and a chipping groove is arranged between the cutting edge and the limiting tooth. The electric chain saw assembly, has simple structure, is convenient to assemble and solves the problem that blades are bent or deviated due to resonance can be effectively.

Abstract: Disclosed is a phone case for diving comprising a housing including a rear housing rotatably connected to one side of front housing and sealingly connected to the other side, and a front housing. A surface of rear housing is connected with a photographing window on one side, and is further connected with an air suction assembly located on one side of photographing window and/or a light-filling assembly located on the other side of air suction assembly. The housing, connected with a function button, has a control module connected inside that is in signal connection with function button and light-filling assembly respectively and connected with phone by Bluetooth. Further disclosed is a method for implementing a phone case for diving, wherein air inside housing is extracted by air suction assembly, so that housing is vacuumed inside for good waterproof performance without steam appearing inside housing, making photographing effect better.
