Description
Technical field
The present invention relates to a kind of nails that can remove in expansion bolt within the walls, and easy to operate is time saving and energy saving, versatile
Expansion bolt extracting tool.
Background technology
Expansion bolt is widely used in building trade, and fixed occasion is especially required at some, as pendent lamp, air-conditioning,
The installation etc. of water heater.Expansion bolt advantage is that fixed object is firm, and installation is simple, the disadvantage is that it is not easy to remove after installation, it tolls breakdown
Wall can be destroyed, dangerous and difficulty can be brought to following construction by not removing, and a kind of dismounting of expansion bolt is designed so passing through
Tool can not also destroy wall body structure easily by expansion bolt from removing within the walls.
Invention content
A kind of can remove is provided the invention aims to overcome the deficiencies in the prior art to follow closely in expanding screw within the walls
Bolt, the extracting tool of time saving and energy saving, versatile expansion bolt easy to operate.
In order to achieve the above objectives, the technical solution adopted by the present invention is：A kind of expansion bolt extracting tool, including spanner,
Screw rod and holder；The holder is provided with stabilizer blade；It is provided with supporting plate on the stabilizer blade；The supporting plate is provided centrally with spiral shell
Bar, screw rod pass through supporting plate center；The screw rod is used with supporting plate and is threadedly coupled；The screw rod upper end is provided with spanner；
Shell fastening clip is provided on the screw rod of stabilizer blade respective side；The shell fastening clip is located in conical sleeve on screw rod；It is described outer
Shell fastening clip is connected in by attachment bolt on screw rod；It is provided with tapered sleeve cylinder on the shell fastening clip；The tapered sleeve cylinder can be with
It is slided on shell fastening clip, and can be by shell fastening clip clamping；The shell fastening clip is divided into epicone folder and lower cone folder two
Part；The epicone folder and lower cone clamp ring are embraced on screw rod；The end of the shell fastening clip is set as stairstepping clamping opening.
Preferably, the attachment bolt passes through screw rod to couple shell fastening clip；And length is not greater than the minimum of tapered sleeve cylinder
Internal diameter.
Due to the application of the above technical scheme, the present invention has following advantages compared with prior art：
A kind of expansion bolt extracting tool of the present invention program, easy to operate, convenient disassembly can be dismantled various sizes of
Expansion bolt, it is versatile, wall body structure is not destroyed, manpower is saved, avoids making troubles to successive projects.
Description of the drawings
Technical scheme of the present invention is further explained below in conjunction with the accompanying drawings：
Attached drawing 1 is a kind of cross-sectional view of expansion bolt extracting tool of the present invention；
Attached drawing 2 is a kind of operating diagram of the dismounting expansion bolt of expansion bolt extracting tool of the present invention；
Wherein：1, spanner；2, screw rod；3, holder；4, shell fastening clip；5, tapered sleeve cylinder；6, attachment bolt；7, expansion bolt
Pull rod；8, the shell of expansion bolt；9, wall；31, stabilizer blade；32, supporting plate；41, epicone presss from both sides；42, lower cone folder；43 stairsteppings
Clamping opening.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is described in further details.
Attached drawing 1-2 is a kind of expansion bolt extracting tool of the present invention, including spanner 1, screw rod 2 and holder 3；It is described
Holder includes stabilizer blade 31；Supporting plate 32 is provided on the stabilizer blade 31；The supporting plate 32 is provided centrally with screw rod 2, screw rod 2
Across 32 center of supporting plate；The screw rod 2 is used with supporting plate 32 and is threadedly coupled；2 upper end of the screw rod is provided with spanner 1；
It is provided with shell fastening clip 4 on the screw rod 2 of 31 respective side of stabilizer blade；The shell fastening clip 4 is located in conical sleeve on screw rod 2,
The end of the shell fastening clip 4 is set as stairstepping clamping opening 43；The shell fastening clip 4 is connected in spiral shell by attachment bolt 6
On bar 2, shell fastening clip 4 and attachment bolt 6 are all clearance fit on radial and axial, and attachment bolt 6 passes through screw rod 2；Institute
It states and is provided with tapered sleeve cylinder 5 on shell fastening clip 4；The tapered sleeve cylinder 5 can slide on shell fastening clip 4, and can be by shell
4 clamping of fastening clip；The shell fastening clip 4 divides presss from both sides 42 two parts for epicone folder 41 and lower cone；The epicone folder 41 is pressed from both sides with lower cone
42 can open certain angle up and down；The epicone folder 41 and lower cone folder 42 are encircled on screw rod 2；The attachment bolt 6
Length is not greater than the minimum diameter of tapered sleeve cylinder 5.
Want to follow closely when the expansion bolt in wall 9 removes, first by 3, holder on wall 9, by 1 turn of spanner
Dynamic screw rod, makes screw rod 2 move axially, screw rod 2 is made to push down the pull rod 7 of expansion bolt, and the pull rod 7 of expansion bolt is pushed back in hole,
The shell 8 of expansion bolt loses radial expansionary force, it is easier to remove, at this moment stairstepping clamping opening 43 stretches into intracavitary and clamps expanding screw
The shell 8 of bolt, then tapered sleeve cylinder 5 is sleeved on shell fastening clip 4, and by its clamping, shell fastening clip 4 is by expanding screw at this time
The shell 8 of bolt clamps, and being rotated further by spanner 1 makes screw rod 2 move out, and shell fastening clip 4 is driven to move out, while by expanding screw
Bolt takes apart；The epicone folder 41 of shell fastening clip 4 and lower cone, which press from both sides 42 two parts, can dismantle various sizes of expansion bolt, lead to
It is strong with property.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be implemented, and it is not intended to limit the scope of the present invention, all according to the present invention
Equivalent change or modification made by Spirit Essence should all cover within the scope of the present invention.
