Description
Technical field
The utility model relates to electric wrench auxiliary device technical fields, especially electric wrench adjustable sleeve.
Background technique
Electric wrench is using power supply or battery as the spanner of power, is the electric tool for tightening and unscrewing bolt and nut.
Use electric wrench that hand is replaced to carry out tightening electric wrench from spanner and work by power of power supply, it is ensured that each bolt
Screwing force all within the limits prescribed, meanwhile, using electric wrench replace manual wrench can greatly improve what bolt was tightened
Speed improves work task efficiency, improves the labor intensity of worker.It is integrally tied using the electric wrench of lithium battery mode at present
Structure is pistol-type structure, and such structure can not be adjusted, and can only carry out screwing bolt end nut, for being located in bolt
Tightening for the nut in portion is very inconvenient, greatly reduces the scope of application of electric wrench.
Therefore a kind of sleeve that can be convenient and screwed and be can conveniently adjust length in the middle part of bolt to nut is designed
It is necessary.
Utility model content
For above situation, for the defect for overcoming the prior art, the utility model provides electric wrench with adjustable set
Cylinder；The scope of application of electric wrench is increased, is improved work efficiency well.
Its technical solution solved includes the cylinder vertically placed, and the lower end surface of cylinder offers blind hole, the upper end of cylinder
Offer square hole, the protrusion that the side wall of blind hole is equipped with multiple circumference uniform distributions and vertically places is equipped in the blind hole of cylinder
Multiple and raised one-to-one vertical key can be offered on the quill that blind hole moves up and down, the outer rim of quill
Slot, protrusion may be stuck in its corresponding keyway, and quill is hollow cylinder shell-like structure, and the lower end of sleeve is equipped with nut set,
The inner hole of nut set opens up the nut card hole of polygon.
The utility model is novel, clever structure, by the quill with certain length and can go up downward
The structure of section realizes well can screw the nut in the middle part of bolt using electronic mode, increase electric wrench
The scope of application improves work efficiency well.
Detailed description of the invention
Fig. 1 is the utility model schematic front view.
Fig. 2 is the utility model top cross-sectional view.
Fig. 3 is that the utility model nut covers bottom view.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
By Fig. 1-3 it is found that the utility model includes the cylinder 1 vertically placed, the lower end surface of cylinder 1 offers blind hole 11,
The upper end of cylinder 1 offers square hole 2, the protrusion 3 that the side wall of blind hole 11 is equipped with multiple circumference uniform distributions and vertically places, cylinder
Be equipped in 1 blind hole 11 can be offered on the quill 4 that blind hole 11 moves up and down, the outer rim of quill 4 it is multiple with
Raised 3 one-to-one vertical keyways, protrusion 3 may be stuck in its corresponding keyway, and quill 4 is hollow barrel shell shape knot
Structure, the lower end of sleeve are equipped with nut set 5, and the inner hole of nut set 5 opens up the nut card hole 6 of polygon.
In order to realize the fixation to 4 position of quill, the side wall of the blind hole 11 is equipped with positioning screw 7, positioning
The inside of screw 7 is placed in inside blind hole 11 through 11 side wall of blind hole, and the outer circle of quill 4 offers multiple and positioning screw
7 corresponding pin holes 8, the inner opposite end of positioning screw 7 may be stuck in pin hole 8 fixation realized to 4 upper and lower position of quill.
In order to realize that fixation can be adjusted in the position in blind hole 11 in quill 4, about 8 pin hole is laid
Have multiple.
In order to realize damping effect in use, the inside of the quill 4 is equipped with pressing plate 9, pressing plate 9 with
Spring 10 is connected between 11 bottom wall of blind hole.
In order to which the height of quill 4 more efficient to nut driving power in use, described is 18-25cm,
The depth of blind hole 11 is 8-15cm.
In order to keep the fixation to quill 4 more efficient, the positioning screw 7 circumference on the side wall of blind hole 11 is equal
It is laid with multiple, the position of positioning screw 7 and the position formation dislocation of protrusion 3.
The utility model is when specifically used, first by the rectangular key connection of the upper end square hole 2 of cylinder 1 and driving motor
Together, driving motor can drive the rotation of cylinder 1 by the cooperation of key-keyway, be equipped in the blind hole 11 of 1 lower end of cylinder
Quill 4, quill 4 are attached by keyway and the cooperation of protrusion 3, and the rotation of cylinder 1 can drive quill 4
Rotation, while quill 4 can be slided up and down on the outer edge surface of cylinder 1 by the cooperation of raised 3- keyway, need to pass through
When electric wrench screw on nut, nut set 5 is sleeved in the nut outer rim for needing to screw at this time, starting driving motor can drive
The rotation and then realization of nut set 5 screw nut, due to, needing to carry out in use to the nut on stay bolt
When screwing, at this time since nut is in the middle position of bolt, the length of bolt will affect the use of electric wrench, at this time can be with
Longer bolt one end is injected in quill 4, is sleeved on bolt by quill 4 and 5 sets of nut set may be implemented
Rotation is carried out on the nut in the middle part of bolt to tighten, in use, pressing plate 9 in quill 4 can be pressed on spiral shell
The end face of bolt can play certain damping effect under the action of spring 10 in use, furthermore when encountering nut away from spiral shell
It when the different length of bolt end, can be slided up and down in blind hole 11 by adjusting quill 4 at this time, increase nut set 5 away from blind
The distance of 11 bottom wall of hole realizes that nut can effectively work in different location on bolt.
The utility model is novel, clever structure, by the quill with certain length and can go up downward
The structure of section realizes well can screw the nut in the middle part of bolt using electronic mode, increase electric wrench
The scope of application improves work efficiency well.
