As preferably, the ABS shell of described upper and lower section is all for being made of one piece by three tube-like envelopes, described EVA soft rubber casing is also for to be made of one piece by three tubulose EVA soft rubber casings, the one-body molded connecting pipe that has connection to reach each other two described connection pipe ends between three described tubulose EVA soft rubber casings, the described button, the inside and outside piston bush of aluminium matter, ABS piston only, piston positioning base, spring assembly and the ABS piston bottom that are connected in described piston shell are three.

As shown from the above technical solution, the beneficial effects of the utility model are:

compared to existing technology, the structure that the piston apparatus of trumpet of the present utility model adopts plastics and aluminium to match, quality is light, cost is low, and non-corrosive, anticorrosive, maintenance also is very easy to, only need to rinse with clear water and get final product, its structure to piston apparatus has been carried out deep improvement, abandoned original copper piston bush fully, be enclosed within closely outside aluminium matter outer piston cover by the EVA soft rubber casing, and be connected with the EVA layer on the outer wall by the ABS piston only, make it be fixed in closely the inside of aluminium matter inner carrier cover, thereby reach when pushing button, button drives the ABS piston only and moves down, the aluminium matter inner carrier cover that EVA layer due to the ABS piston only by the outside has reached with its outside closely cooperates, thereby the ABS piston only directly moves down with aluminium matter inner carrier cover, coordinating of the smoothness of sliding between aluminium matter inner carrier cover and aluminium matter outer piston cover, make the spiral venting cavity on the ABS piston only switch to different ventilation routes in the position corresponding to described connection pipe end, when unclamping button, on spring assembly, bullet resets button, it has substituted original copper piston bush, by structurally improveing, when making it reach the same tonequality of piston apparatus with copper trumpet, also had advantages of above-mentioned, have certain economic worth and industrial value.
