It is all not quite similar to the general diameter of fuel pump fastening bolt of different automobile types, and existing dismantling device can only be directed to one species
The fuel pump fastening bolt of type, versatility be not strong.
Utility model content
The purpose of this utility model is to provide a kind of adjustable fuel pump fastening bolt dismantling devices, which can be with needle
The fastening bolt of different types of fuel pump is dismounted, it is easy to operate.
In order to achieve the above objectives, base case provided by the utility model is as follows: a kind of adjustable fuel pump fastening bolt
Dismantling device, including tool body and multiple regulating arms for being used to clamp fastening bolt, the tool body is circumferentially uniformly provided with
Multiple support arms, the quantity of the support arm and the quantity of regulating arm are equal, the one end of the regulating arm and support arm far from tool body
It is slidably matched；The support arm is equipped with the fixed part of fixed support arm and regulating arm.
Be using the beneficial effect of this base case: 1. on tool body, equipped with it is multiple divide equally support arms, support arm with
The regulating arm connection for clamping fastening bolt, makes fastening bolt uniform force, easily facilitates disassembly.
2, regulating arm and support arm are slidably matched, then can according to the fastening bolt of different-diameter, along support arm slidable adjustment arm,
Regulating arm is adjusted at a distance from support arm, is then again fixed regulating arm and support arm with fixed part, reaches and changes dismantling device diameter
Effect, can be used for dismounting the fastening bolt of different-diameter.
Further, the quantity of the support arm is three.Three support arms and three regulating arms cooperate, and can both guarantee to fasten spiral shell
Bolt uniform force, and the structure of dismantling device is simplified.
Further, each support arm is equipped with strip-shaped hole far from tool body one end, and described regulating arm one end is equipped with through-hole,
The fixed part passes through through-hole and strip-shaped hole and can fix regulating arm and support arm.When connecting regulating arm and support arm, will fix
Portion one end passes through through-hole and strip-shaped hole, and regulating arm then can be moved along strip-shaped hole, that is, reach change support arm and regulating arm away from
From after arm to be regulated reaches suitable location, regulating arm and support arm being consolidated with fixed part to be adapted to the fastening bolt of different-diameter
Surely it can be used to dismounting fastening bolt.
Further, the strip-shaped hole side is equipped with scale strip.It can be according to the diameter of different fastening bolts, by regulating arm
Adjust the corresponding position of scale strip, can fast, accurately adjust regulating arm to need position, it is easy to operate.
Further, the fixed part includes screw bolt and nut, and the bolt passes through through-hole and strip-shaped hole and and nut thread
Cooperation, screw bolt and nut is not only low in cost, but also convenient for operation and good fixing effect.
Further, each regulating arm tail end is equipped with the positioning spigot that can cooperate with fastening bolt.Because of fastening bolt
End is provided with chamfering, opens up positioning spigot in regulating arm tail end, and when dismounting fastening bolt, positioning spigot can be with fastening bolt
Chamfering at be fitted close, keep dismantling device more preferable to the clamping effect of fastening bolt, power transmission is more effective.
Further, the tool body upper end is equipped with the square hole cooperated with ratchet spanner.Square hole can be with ratchet wheel pulling etc.
Tool is used cooperatively, and increases torque, keeps people more laborsaving in dismounting.
Detailed description of the invention
Fig. 1 is a kind of top view of adjustable fuel pump fastening bolt dismantling device of the utility model；
Fig. 2 be in Fig. 1 A to cross-sectional view.
Specific embodiment
It is further described below by specific embodiment:
Appended drawing reference in Figure of description includes: tool body 1, support arm 2, strip-shaped hole 3, scale strip 4, regulating arm 5, side
Hole 6, positioning spigot 7, bolt 8, nut 9.
Embodiment is substantially as shown in Fig. 1: a kind of adjustable fuel pump fastening bolt dismantling device, including tool body 1,
Fixed part and multiple regulating arms 5 for being used to clamp fastening bolt.1 upper end of tool body is equipped with the square hole 6 cooperated with ratchet spanner.
Tool body 1 is circumferential to be uniformly provided with multiple support arms 2, and the quantity of support arm 2 is equal with the quantity of regulating arm 5, adjusts in the present embodiment
The quantity of arm 5 and support arm 2 is three.As shown in Fig. 2, support arm 2 includes the first linkage section and the second linkage section, the first linkage section
It is obliquely installed and the first linkage section both ends is connect with tool body 1 and the second linkage section respectively.Second linkage section be it is horizontally disposed,
Second linkage section is equipped with strip-shaped hole 3 far from one end of the first linkage section, and 3 side of strip-shaped hole is equipped with scale strip 4.Regulating arm 5 includes
Horizontal connection section, vertical linkage section and clamp segment, are provided with through-hole in the middle part of horizontal connection section, horizontal connection section one end with connect vertically
Duan Shangduan connection, vertical linkage section lower end are connect with clamp segment, and clamp segment is that the horizontally disposed and clamp segment other end is equipped with vertically
Clamping plate.The positioning spigot 7 cooperated with fastening bolt is equipped in clamp segment lower end.Fixed part includes bolt 8 and nut 9, spiral shell
Bolt 8 passes through through-hole and strip-shaped hole 3 and is threadedly engaged with nut 9.
When connecting regulating arm 5 and support arm 2, one end of bolt 8 is passed through into through-hole and strip-shaped hole 3, it then can be along bar shaped
Regulating arm 5 is moved in hole 3, that is, reaches and change support arm 2 at a distance from regulating arm 5, to be adapted to the fastening bolt of different-diameter, wait adjust
After joint arm 5 reaches suitable location, nut is turned, regulating arm 5 and support arm 2, which are fixedly clamped, with nuts and bolt can be used to dismount
Fastening bolt.When adjusting the position of regulating arm along strip-shaped hole, regulating arm 5 can also be adjusted and arrive the corresponding position of scale strip 4,
It can fast, accurately adjust regulating arm 5 and arrive the position needed, it is easy to operate.Square hole 6 can cooperate with tools such as ratchet wheel pullings
It uses, increases torque, keep people more laborsaving in dismounting.
Because fastening bolt end is provided with chamfering, positioning spigot 7 is opened up in 5 tail end of regulating arm, when dismounting fastening bolt,
Positioning spigot 7 can be fitted close at the chamfering of fastening bolt, keep dismantling device more preferable to the clamping effect of fastening bolt, be passed
Power is more effective.
