Abstract
The utility model discloses a special sleeve wrench, comprising a sleeve head and sleeve rod; a sleeve hole is arranged on the sleeve head; the sleeve hole is frustum-shaped; a sleeve rod seat is arranged at the other end of the sleeve head, corresponding to the sleeve hole; the sleeve rod seat is connected with the sleeve rod; the sleeve rod seat is movably connected with the sleeve rod; the sleeve rod seat is fixedly connected with the sleeve rod; a through hole is arranged at the other end of the sleeve head, corresponding to the sleeve hole; the sleeve rod is threaded through the through hole; and the sleeve rod can be fixedly connected, movably connected or threaded with the through hole. The special sleeve wrench has the advantages that as the sleeve hole on the sleeve head is frustum-shaped and is matched with the external surface of a frustum-shaped nut, the frustum-shaped nut can be easily tightened or opened, so as to prevent the objects tightened with the frustum-shaped nuts being damaged by lawbreakers and ensure the security of the tightened objects to protect the state, collective or personal property of citizens from being infringed; moreover, the user can easily replace the nuts and maintain the tightened objects.
Description
Technical field
The utility model relates to a kind of kit of securing member, particularly a kind of special sleeve spanner.
Background technology
At present, no matter be, be widely used as the nuts and bolt of securing member in various buildings, bridge or on the vehicles.During use, the user will be appropriate to the spanner of nut size, nut screwing clamping or unscrew, promptly object can be tightened or loosened.When making things convenient for the user to use, also there is very big defective in nuts and bolt of the prior art as securing member: because the profile of most of nuts all is a prism-shaped, its each lateral surface is vertical plane, and the existing mostly spanner that uses, also all design at this kind nut, the medial surface of spanner is vertical plane, and the vertical plane of this vertical plane and nut cooperatively interacts, and just can very like a cork nut be unscrewed or tighten.Because such spanner is very general, this just provides convenience for stealer or saboteur, makes law-breaker's purpose reach easily, makes the property of country, collective or individual citizens suffer a loss.Particularly be applied to away from the nut on city, the bridge that does not have enough safety prevention measures, railway and other critical facility, in case steal or destroy after being opened by the lawless person its fastening main parts size, gently then cause material damage, heavy then might cause that bridge caves in, the impaired major accident that causes car crash of railway.
For this reason, people invented a kind of nut body be the terrace with edge shape can be antitheft nut, its lateral surface is the inclined-plane, general spanner can't open it.With regard to for the lawless person destroys, increased great difficulty like this, thus guaranteed the safety of fastening object, that is protected the property of country, collective or individual citizens not encroached on.But because this nut body is designed to the terrace with edge shape, its outer surface is the inclined-plane, and general spanner can't open it.In safe antitheft, make people when it is changed and keeps in repair, bring inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of and terrace with edge shape nut matching used, and convenient to its special sleeve spanner of changing and fastened object being keeped in repair at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of special sleeve spanner, comprise pullover and loop bar, and it is characterized in that: a described end on pullover is provided with trepanning, and described trepanning is the terrace with edge shape; Described pullover on, with respect to the other end of described trepanning, be provided with one the cover pole socket, described cover pole socket connects described loop bar;
Described cover pole socket and described loop bar are for flexibly connecting; Described cover pole socket and described loop bar are for fixedlying connected;
Described pullover on, with respect to the other end of described trepanning, be provided with perforation, described loop bar is arranged in this perforation; Described loop bar and described perforation are for fixedlying connected, flexibly connect or being spirally connected.
Compared with prior art, advantage of the present utility model is because the pullover inner surface of going up trepanning of the present utility model is designed to the terrace with edge shape, be complementary with the outer surface of terrace with edge shape nut, thereby can be easily terrace with edge shape nut screwing clamping or twist and open.So both prevented that the lawless person from destroying using the fastening object of terrace with edge shape nut, guaranteed the safety of the fastening object of institute, that is protected the property of national, collective or individual citizens not encroached on; Making the user very easily it be changed to reach again keeps in repair fastened object.The utility model production cost is not high, but benefit is huge.Economical and practical, market prospects a slice light.
