Pressure, buffer spring 313 push driving piston 312 to stretch out so that are arranged on the claw of the two-stage actuator 32 of driving pistons end
323 close wellhead connector control lever upper end and the soft contacts therewith being arranged on underwater horizontal type production tree；Again to secondary drive
32 pressure supply of device, and drive in two-stage actuator 32 and piston rod 13 is driven to stretch out, so as to push the claw of 13 lower end of driving piston rod
Seat 326 and claw 323 are moved to claw sleeve 324, and due to the limitation in space, claw 323 is by 324 Internal periphery of claw sleeve
The extruding in type face forces claw 323 by open configuration in state variation is tightened, realizes that claw 323 grips wellhead connector manipulation
Then bar upper end presses to level-one driver 31 again, driving piston 312 stretches out, the wellhead connector behaviour that claw 323 is pushed to grasp
Control lever moves down, and completes underwater horizontal type production tree and is installed on well head（It is locked between underwater horizontal type production tree and well head）.
C, underwater horizontal type production tree installation tool is recycled from underwater horizontal type production tree
By underwater horizontal type production tree installation tool from underwater horizontal type production tree time receiving last time, the pressure of two-stage actuator of releasing 32
Power, driving piston rod 322 are retracted under the action of resetting spring 327, and claw 323 is detached from 324 contoured profiles of claw sleeve, by contracting
Tight state change is open configuration, and level-one driver 31 reversely applies pressure, and driving piston 312 is reversely retracted so that claw 323
It is detached from wellhead connector control lever, then applies unlocking pressure to hydraulic pressure bolt-lock tool again, under the action of sealing ring 23, driven
Rotating ring 24 moves backward, and latch segment 25 is resetted from tree body Internal periphery to be detached from, after completing unlock, it will be able to by underwater horizontal type production tree
Installation tool distancing recycling.When the hydraulic-driven failure of production tree latch assembly 2, mechanical unlock rod is equipped on ontology 20
26, as secondary release function, it can be manipulated by manipulator in the case where pressure-driven unlocks failure and carry out mechanical solution
