Specific implementation mode
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, the set for giving the utility model pricks the structural schematic diagram of cushion rubber circle device, Fig. 2 gives Fig. 1
The sectional view of middle Section A-A, shown in upper circle device be made of annular solid 1 and multiple support arms 2, shown annular solid 1 plays fixed and branch
Support acts on, and the center of annular solid 1 is through-hole 3, and during upper cushion rubber 15, the front end of entire reamer device 13 or reamer device 13 can be from
It is passed through in through-hole 3.The periphery of 1 front end of annular solid is fixed with annular slab 4, in use, user pinches annular solid 1 with hand, due to
Blocking and position-limiting action of the annular slab 4 to user's finger are more advantageous to and carry out grip to entirely upper circle device, be advantageously implemented
Cushion rubber operates.The quantity of shown support arm 2 is 3 or 3 or more, and support arm 2 is by first horizontal segment 5, interior trisection 6, the second horizontal segment 7
It is formed with head 8.
As shown in figure 3, giving the partial enlarged view of support arm in the utility model, one end of first horizontal segment 5 is fixed on
On annular solid 1, the other end and one end of interior trisection 6 are mutually fixed, and the other end of interior trisection 6 is fixed with 7 phase of the second horizontal segment, head
8 are fixed on the outer end of the second horizontal segment 7.Since 6 ecto-entad of interior trisection is bent so that the head 8 on all support arms 2 is drawn close
Together or on the smaller circle of diameter, which is located at compared with the center of circle of roundlet on the axis of annular solid 1, in order to by reamer
Cushion rubber 15 on device 13 extends to larger diameter by small diameter, and on on sucker 16.
The front end of shown second horizontal segment 7 is front retaining surface 9, and during Shang Quan, front retaining surface 9 is used to carry out cushion rubber 15
Blocking and limit, to realize that pushing away cushion rubber 15 acts.The top on head 8 is upper arc surface 11, and upper arc surface 11 can be used and sucker
The consistent shape of 16 outer circle radian, both ensure that lifting of the upper arc surface 11 to cushion rubber 15 avoided making cushion rubber when pushing away circle
At damage, as shown in figure 4, giving structural schematic diagram of the upper circle device of the utility model when reamer device above pushes away cushion rubber, Fig. 5 gives
Cushion rubber is pushed into structural schematic diagram on sucker by the upper circle device for having gone out the utility model, when cushion rubber 15 is pulled on sucker 16 it
Afterwards, during support arm 2 is retracted, upper arc surface 11 can guarantee that cushion rubber 15 stays on sucker 16, without by support arm 2 under.Head
The lower part in portion 8 is lower convex surface 12, and arc or triangle can be used in lower convex surface 12, and lower convex surface 12 can reduce head 8 and reamer device 13
Contact area so that head 8 and the contact of guide groove 17 on reamer device 13 are " line contact " form, realize support arm 2 and are expanding
Bore the smooth sliding on device 13 so that it is slimmer and more graceful to push away circle action.
The rear portion of 7 junction of shown head 8 and the second horizontal segment is rear retaining surfac 10, after upper cushion rubber 15, passes through rear gear
Face 10 is stuck on the forward position of reamer device 13, is conducive to together take back the connection reamer of support arm 2 device 13, is realized reamer device 13 from suction
It is unloaded on disk 16 so that operation is more convenient.Shown in annular solid 1 and support arm 2 integral structure of injection molding can be used, both
It ensure that the fastness of circle device structure, and reduce the production cost.
As shown in Figures 6 to 9, the usage state diagram of the upper circle device of the utility model is given；In use, first by glue
Circle 15 is sleeved on the thin head end of reamer device 13, as shown in fig. 6, upper circle device is then held, and it is adjacent so that the support arm 2 enclosed on device is inserted into
Ribs 14 between, circle device is then enforced, as shown in fig. 7, until shifting upper circle device the thick head end of reamer device 13 onto.
Then continue to push cushion rubber 15 forward with circle device, until cushion rubber 15 is located at the periphery of sucker 16, as shown in Figure 8；Finally, hand is pinched
Support arm 2 pulls back circle device, and cushion rubber 15 can be made to slide and be sleeved on sucker 16 from support arm 2, as shown in figure 9, simultaneously, by
In the position-limiting action of rear retaining surfac 10 on support arm 2 and 13 forward position of reamer device, reamer device 13 can be separated from sucker 16, is realized
Upper cushion rubber on sucker 16.
