Through adopting above-mentioned technical scheme, offer the space for the operation groove provides, make operation groove position more reasonable, the rotatory lantern ring of staff of being convenient for.

The utility model discloses further set up to: the operating slots are oppositely arranged.

Through adopting above-mentioned technical scheme, conveniently rotate the lantern ring.

The utility model discloses further set up to: and an anti-falling block is arranged on the outer wall of the edge.

Through adopting above-mentioned technical scheme, lantern ring threaded connection anticreep piece and caulking groove lateral wall extrusion contact behind holding tank inner wall further prevent that the lantern ring from deviating from the body.

The utility model discloses further set up to: the lantern ring is provided with a chamfer angle relative to the joint of the end provided with the edge and the inner wall.

Through adopting above-mentioned technical scheme, the bolt of being convenient for passes the lantern ring, prevents that lantern ring tip from withstanding the bolt head and leading to the lantern ring by ejecting holding tank.

The utility model discloses further set up to: the lantern ring is embedded with a magnet ring relative to the end part of one end provided with the edge.

Through adopting above-mentioned technical scheme, prevent that the lantern ring from deviating from the body.

To sum up, the beneficial effects of the utility model are that:

1. the lantern ring is fixed through being in threaded fit with the body, and because the thread direction of the outer wall of the lantern ring is opposite to that of the threaded hole, when the bolt is screwed into the nylon lock nut, the deeper the bolt is screwed, the firmer the lantern ring is in threaded fit with the body under the action of force; the arrangement of the operation groove is convenient for later-period workers to screw out the lantern ring by means of tools; the structure is simple, and the disassembly and the assembly are convenient;

2. the lantern ring threaded connection is in anti-disengaging block and caulking groove lateral wall compressive contact behind the holding tank inner wall, further prevents that the lantern ring from deviating from the body.
