The second connector on, some pieces of stretchable sheets form the cavity of cylinder, the other end of the stretchable sheet and the bent sheet
One end connection, the bent sheet bends towards the cavity.
Further, the second joint screw thread of the ball pawl is connected on first connector.
Further, the first connecting rod is connected to by joint pin on the second connecting rod.
Further, the second connector, stretchable sheet and the bent sheet are integrally formed.
Further, the stretchable sheet is 6 pieces.
By adopting the above-described technical solution, the beneficial effects of the utility model are：The ball pawl include the second connector,
Bent sheet and stretchable sheet, stretchable sheet are flexed outward when being subject to active force, and steel ball is taken in the sky of ball pawl during stretching, extension
Intracavitary, bent sheet can prevent the steel ball of cavity energy from coming off, steel ball is smoothly taken out from coring tool.The ball pawl connects
It is connected on first connector, first connector is connected to second connecting rod, and second connecting rod passes through hinge with first connecting rod
Connection, easy to which steel ball retracting device is recycled steel ball in coring tool.
The utility model has the advantages of simple structure, easy to operate, can be in the case where not dismantling coring tool, by coring tool
Steel ball take out, eliminate dismounting process, save time and manpower.

Embodiment
Reference Fig. 1-4, illustrate the embodiment of the utility model.
A kind of coring tool steel ball retracting device, including handle 1, first connecting rod 2,3 and first connector 4 of second connecting rod, institute
The one end for the first connecting rod 2 stated is welded on the handle 1, and the other end of the first connecting rod 2 is hinged on described the
One end of two connecting rods 3, the other end of the second connecting rod 3 is welded on first connector 4, in first connector
Ball pawl 5 is provided with 4, the ball pawl 5 includes the second connector 6, bent sheet 7 and stretchable sheet 8,6 screw thread of the second connector
It is connected on first connector 4, one end of the stretchable sheet 8 is connected on second connector 6, and some pieces flexible
Piece 8 forms the cavity 9 of cylinder, and the other end of the stretchable sheet 8 is connected with one end of the bent sheet 7, and described is curved
Tabs 7 bends towards the cavity 9.
Preferably, the second connector 6 of the ball pawl 5 is threaded on first connector 4.First connector 4 with
Second connector 6 is threadedly coupled, it can be achieved that dismantle separation, when ball pawl 5 or second connecting rod 3 are damaged, can by the first connector 4 with
Second connector 6 separates, and replaces the part of damage, steel ball retracting device can normal use, reduce manufacture cost, while ball pawl
5 are detachably connected with second connecting rod 3, easy to store, carry.
Preferably, the first connecting rod 2 is connected to by joint pin on the second connecting rod 3, due to coring tool
It is long tubular, the first connecting rod 2 and second connecting rod 3 of corresponding steel ball recycling instrument are longer, and two connecting rods are by hinge pin connection, just
Fold, be convenient for carrying in by connecting rod.
Preferably, for strengthen the utility model ball pawl 5 intensity, the second connector 6, stretchable sheet 8 and the bent sheet 7
It is integrally formed.
