Further, hinged seat is provided on the inside of installing plate on the Mobile base, the swipe fixed plate inner end is set
Connecting seat is equipped with, the connecting rod both ends are movably set in by shaft on hinged seat and connecting seat respectively.
Further, at least two limited posts are provided on the limit base；Mounting groove, institute are provided on the limit base
It states and spring is provided in mounting groove, the spring end is fixedly connected with limited post, and the limited post stretches out limit base to movement
Beneficial effects of the present invention：After limited post stretches into limit hole, the Mobile base that is threadedly coupled with rotation axis can not be with
It is rotated together with rotation axis, under the action of screw thread, the Mobile base of both sides is opposite or moves toward one another；It cuts with scissors respectively at the both ends of connecting rod
It connects on Mobile base and swipe fixed plate, when Mobile base transverse movement, swipe fixed plate is in that can raise or decline in card slot, just
The diameter of adjustable cleaning roller, to adapt to different swipes or besom and different requirements.
1st, rotation axis is hollow cylinder, and inside can store water, is connected by rotary joint with the water tank in sweeper,
The hydraulic pressure in water tank is entered in rotation axis by water pump, water is flowed by flexible water pipe in the runner in swipe fixed plate, then is passed through
Nozzle is sprayed to from apopore on besom, can moisten besom, reduces the dust raised when cleaning.
2nd, besom fixed plate is arranged in the groove in swipe fixed plate, and is passed through bolt and be connected with swipe fixed plate, just
It in dismounting, safeguards, while increases the mounting stability of besom fixed plate and swipe fixed plate.
3rd, limited post is arranged at by spring in the mounting groove on limit base, when limit base is moved to connecting seat, /V
Column can be first with connecting seat end contact and compressing spring, and when limit hole turns to the position of limited post, limited post can stretch into
In limit hole, limit base is facilitated to be connected with connecting seat.

In order to which those skilled in the art is made to more fully understand technical scheme, below in conjunction with the accompanying drawings to the present invention into
Row is described in detail, and the description of this part is only exemplary and explanatory, should not there is any limitation to protection scope of the present invention
As shown in Fig. 1-Fig. 7, concrete structure of the invention is：It include rotation axis 1, the rotation axis 1 by belt with
The motor connection being arranged in compartment, the rotation axis 1 are arranged at underbody, and the 1 outer surface both sides of rotation axis are provided with outer spiral shell
Line, the rotation axis both sides are threaded with Mobile base 2, and the installing plate 3 of annular, the installation are provided on the Mobile base 2
Annular is provided with the card slot 4 of outboard end opening on plate 3, is movably set with swipe fixed plate 5 in the card slot 4, the swipe is consolidated
