The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of specific purpose tool of installing and dismantling special-shaped anti-theft bolt, comprise spanner, also comprise pretension sleeve and the fastening sleeve made by elastomeric material, described pretension sleeve is provided with in its underpart to the conical surface that extends out and opening, and described pretension lower cartridge diameter of bore and ball-crown body bottom surface, special-shaped anti-theft bolt nut top diameter are complementary; Described fastening sleeve comprises inner sleeve and outer sleeve, described inner sleeve comprises spring leaf and lower ring body, relative with lower ring body respectively both sides, the two ends of described spring leaf connect, lower ring body is made up of two identical hemizonids, the inner ring surface of lower ring body is identical with the external surface shape of the fastening impetus cylinder of special-shaped anti-theft bolt, and the cross section outer shroud opposite side distance size of lower ring body is greater than ball-crown body bottom surface, special-shaped anti-theft bolt nut top diameter; The inner ring surface of described outer sleeve and the outer ring surface of inner sleeve are complementary, and described outer sleeve top is provided with the prism that is complementary with spanner.
The utility model can also adopt following technical measures:
Described installation and dismantle the specific purpose tool of special-shaped anti-theft bolt is characterized in that: the lower ring body of described inner sleeve and spring leaf riveted joint.
Described installation and dismantle the specific purpose tool of special-shaped anti-theft bolt, it is characterized in that: described inner sleeve also comprises the monoblock type upper ring body, and described spring leaf is for connecting upper ring body and lower ring body two, and the shape of described upper ring body is identical with the shape of described lower ring body.
Described installation and dismantle the specific purpose tool of special-shaped anti-theft bolt, it is characterized in that: described lower ring body is the hexagonal ring body.
Described installation and dismantle the specific purpose tool of special-shaped anti-theft bolt, it is characterized in that: the opening of described pretension lower cartridge is uniform 4.
Described installation and dismantle the specific purpose tool of special-shaped anti-theft bolt, it is characterized in that: the top of described pretension sleeve is provided with the knurled portion of Gong controlling.
Described installation and dismantle the specific purpose tool of special-shaped anti-theft bolt, it is characterized in that: described spanner is a box spanner.
Advantage and the good effect that the utlity model has are: the utility model is simple and practical, is easy to processing, cost is low, except that pretension sleeve and fastening sleeve need select for use as the case may be special-purpose form, associated spanner is a universal standard part; Can be widely used in the fixing of outdoor facilities, equipment, can be different users and be equipped with different bolts and special-purpose the installation and extracting tool, under the situation of not using special-purpose kit, be difficult to demounting bolt, can effectively contain larceny, for outdoor equipment provides effective safety guarantee.Prevented the crime means of the demolition that stealer is habitual effectively, prolonged crime time, strengthened the crime difficulty, created advantage for public security department solves a case.
