Specific implementation mode
As shown in Figure 1, the utility model includes oil cylinder 9, piston 8, support tube 5, automated tool anchor assemblies.The support tube
5 rear ends are threadedly coupled with 9 front inner wall of the oil cylinder, and front end is equipped with limiting plate backing plate 1 and support tube nut 2.In the piston 8
Between be fin structure, big plug 6 is provided between fin and the support tube 5, be formed as between fin and big plug 6 tensioning oil
Chamber A；9 rear end of the oil cylinder is equipped with compression ring after rear sealing plate 11 and 12, is formed between rear sealing plate 11 and the fin of piston 8
Backhaul oil pocket B；The automated tool anchor assemblies are arranged in 8 endoporus of piston.
The automated tool anchor assemblies include tool anchor slab 15, tool clamping piece 14, automated tool anchor pressing plate 17, top cover 18,
Backhaul set 16, backhaul cover pressing plate 4, and backhaul covers limiting plate 3.The tool anchor slab 15 is connect with 8 hole internal thread of piston, and rear end is equipped with
Automated tool anchor pressing plate, the automated tool anchor slab pressing plate 17 are connect with bolt 13, and the bolt 13 passes through tool anchor slab and returns
Journey covers the structure that pressing plate 4 is affixed, and formation tool anchor slab 15 is slided with bolt 13.The backhaul covers 16 one end and tool clamping piece 14 is small
End connects, and the other end passes through backhaul set pressing plate 4 and is equipped with fin, and fin is blocked by backhaul set pressing plate 4；The backhaul covers limiting plate
3 are provided with counterbore corresponding with fin to be limited to backhaul set 16.
As shown in Fig. 3,4,5, the tool clamping piece 14 is placed on the anchor hole rear end of tool anchor slab 15, and large end face is recessed circular cone
