Connect, sand blasting pipe is fixed, so as to improve the positional precision of sand blasting pipe, reduce its position in consumable accessory Renewal process and become
Change.
Further, the shaft shoulder, described chuck clamping nut one end and shaft shoulder clamping are provided with the cylindrical sidewall, separately
One end and sprayer body threaded connection；When chuck clamping nut compress sprayer body and and sprayer body be fastenedly connected when, the (operating) water nozzle
Contradicted with shower nozzle intracoelomic cavity, the collet end face and shower nozzle intracoelomic cavity have gap.
By such scheme, the end face of (operating) water nozzle and inner chamber closely contradicts, and is then compressed using collet, and leads to
Cross chuck clamping nut to fix collet and sprayer body, improve the position essence between (operating) water nozzle, mulling room and sprayer body
Degree, and then also just improve the positional precision of the sand blasting pipe directly contacted with mulling room.Between collet end face and inner chamber
Gap, which can allow between (operating) water nozzle and inner chamber, realizes benign contact.
Further, the nose cone is circumferentially high is evenly equipped with some necking grooves, and the necking groove is along nose cone
Axis direction is set.
By such scheme, during the setting of necking groove make it that sand blasting pipe clamping nut screws, nose cone can be
Inwardly deformed upon under the extruding of sand blasting pipe clamping nut, so as to which sand blasting pipe be compressed.
Further, the cylindrical end outer wall is provided with spanner groove.
By such scheme, spanner groove is easy to screw sand blasting pipe clamping nut by spanner, ensures collet to sand blasting
The clamping force of pipe.
Further, the nose cone is provided with the face of cylinder of the diameter less than cylinder close to one end side wall of cylinder.
By such scheme, the face of cylinder is provided for avoiding in installation process in the screw thread of sand blasting pipe clamping nut
Caused interference between footpath and collet.
Further, the junction of nose cone and cylinder is provided with escape.
By such scheme, escape can reduce the wall thickness of collet, be easy to when screwing sand blasting pipe clamping nut,
The conical end of spring joint is deformed.
Further, collet upper end side wall is provided with the mounting hole for sand-feeding tube insertion.
By such scheme, mounting hole facilitates the installation of sand-feeding tube.
In summary, the utility model has the advantages that：
Sand blasting pipe and collet, collet and sprayer body inner chamber between be nested, so as to ensure that sand
Axiality between jet pipe and sprayer body, fixed between collet and sprayer body by chuck clamping nut, so as to ensure that
Positional precision between collet and sprayer body；Outside sand blasting pipe clamping nut set and nose cone, and the inner circle of its conical end
The conical surface compresses nose cone, during it is screwed with collet screw thread, conical end will pressure cone head inwardly produce it is few
Deformation is measured, is closely connected so that being formed between the sand blasting pipe that nose cone and its internal engagement are set, by sand blasting pipe
Fix, so as to improve the positional precision of sand blasting pipe, reduce its change in location in consumable accessory Renewal process.
