Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described, the following example, only for illustration of the technical solution of the utility model, does not limit protection domain of the present utility model.
Embodiment:
As Figure 1-4, the product of the present embodiment comprises two pieces of main fixed heads be oppositely arranged 1 and the corresponding axis 3 of at least one pair of spreading wheel 2, it is two right that spreading wheel 2 in the present embodiment has, and two are arranged for front and back, each spreading of two pairs of spreadings wheel 2 is taken turns 2 in the same plane, and shape size is identical, main fixed head 1 and spreading wheel 2 are metal material.
The axis 3 of the present embodiment is rotatably connected between two pieces of main fixed heads 1, and axis 3 both sides are respectively rotationally connected spreading wheel 2, a two spreadings wheel 2 can along the synchronous equidistant counter motion of axis 3.
The present embodiment also includes bearing 4, sync screw pin 5, stop screw pin 6 and bearing block 7, bearing block 7 two is a pair, by the cross-under of at least two sync screw pins 5 between pair of bearing 7, this is connected with main fixed head 1 respectively by least two stop screw pins 6 both sides, outside of bearing block 7, bearing block 7 is connected to the both sides of axis 3 respectively by positive/negative thread 31, bearing block 7 can be realized along the synchronous equidistant counter motion of axis 3, bearing 4 is arranged on bearing block 7, and spreading wheel 2 is arranged on bearing block 7 by bearing 4.
The sync screw pin 5 of the present embodiment is fixed in the screwed hole in a bearing block 7 by screw thread, and one end is stretched in another bearing block 7 in addition, ensures that the axial location of two bearing blocks 7 is synchronous with this.
The stop screw pin 6 of the present embodiment is connected fastening by the screw thread of one end with two screwed holes in a bearing block 7, and one end is stretched in the hole in main fixed head 1 in addition, limits the rotary motion of two bearing blocks 7 with this.
The present embodiment also includes axis axle bed 8, shaft end nut 9 and handwheel 10, and axis axle bed 8 is connected with main fixed head 1, and axis 3 is axially connected in the middle of two axis axle beds 8; The axle head of axis 3 is provided with shaft end nut 9, and handwheel 10 matches with shaft end nut 9, regulates axis 3 to rotate to realize handwheel 10.
