Fixing screws make fixing screws be fixedly connected with block and fixed plate, will consolidate until fixing screws are transferred to third threaded hole bottom
Determine that device is stable to be mounted in fixed plate；It, will fixed spiral shell when positioning drill bit needs to repair replacement using the long period
Nail is produced out of threaded hole, then convex block is extracted out of groove, can easily be removed fixed device and be tieed up to positioning drill bit
Repair replacement；By contacting with each other for raised line and groove, reduce the contact area of convex block and groove, increases the pressure of convex block and groove
By force, convex block and groove is made to form closer secure fit；The second threaded hole and third threaded hole are carried out by fixing screws
It is fixed, link block is stably fixed in fixed plate, the fixed effect of the second equipment box and fixed plate is increased.
Embodiment 3:
As depicted in figs. 11-12, the present embodiment the difference from embodiment 1 is that: be additionally provided with fixation on 11 inner wall of first through hole
Component；The petroleum pipeline being inserted into preventer is fixed by fixation kit, petroleum pipeline is avoided to generate vibration when the oil is delivered,
The connection effect for influencing petroleum pipeline and preventer, promotes the leakproofness of preventer, avoids the generation of gas blowout accident.
The fixation kit includes the second mounting plate 5 being set on 11 inner wall of first through hole, is set to second peace
Connecting spring 54 in loading board 5 and the fastening plates 51 being fixed on the connecting spring 54；Fixation kit is two groups, is installed respectively
In first through hole inner wall two sides, after petroleum pipeline is inserted into first through hole, petroleum pipeline is placed between the two pieces of fastening plates in left and right,
By left and right two pieces of fastening plates to petroleum pipeline rise fixed function, avoid petroleum pipeline generate when the oil is delivered vibration influence petroleum pipeline with it is close
The sealing effect for sealing block, promotes the leakproofness of preventer.
Guide plate 52 is equipped at the top of the fastening plates 51, the guide plate 52 is obliquely installed, and the 52 top bore of guide plate is greater than
The 52 bottom bore of guide plate；When petroleum pipeline is inserted into first through hole, oil transportation bottom of the tube touches guide plate, petroleum pipeline along
Guide plate moves down, and oil transportation bottom of the tube pushes fastening plates toward both sides under the action of guide plate, makes fastening plates toward first through hole two
Side motion compresses connecting spring, enters in the fastening plates of two sides convenient for petroleum pipeline；It is acted on, is pushed tight by the elastic force of connecting spring
Solid plate and petroleum pipeline are mutually close to forming fastening plates and petroleum pipeline and cooperate, play fixed effect to petroleum pipeline；By guide plate top opening
Diameter setting is greater than guide plate bottom, makes petroleum pipeline be easier to enter in guide plate, enters in fastening plates along guide plate inner wall, and tight
Solid plate forms secure fit.
52 bottom of guide plate is equipped with the first ball 521, and the fastening plates 51 are equipped with the second ball 511；Pass through first
The setting of ball is easier to enter in fastening plates along guide plate, avoids guide plate and fastening plates after entering petroleum pipeline in guide plate
Junction to petroleum pipeline rise inhibition；By the setting of the second ball, the frictional force of petroleum pipeline and fastening plates is reduced, is made defeated
Oil pipe can be moved up and down along fastening plates.
54 two sides of connecting spring are equipped with connection component 53, and the connection component 53 is including attachment base 531 and is set to institute
State the motion bar 532 in attachment base 531；The 5th movable chamber 5311 is equipped in attachment base 531, motion bar can be along the 5th movable chamber
Inner wall is moved；Position-limiting action is played to fastening plates by connection component, petroleum pipeline is avoided to go up and down along fastening plates inner wall
Fastening plates are driven to move together when movement, so that connecting spring is distorted influences the service life of connecting spring.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
