Description
Technical field
The utility model relates to hand-operated tools technical field, specifically a kind of can the spanner of fishbolt head.
Background technology
In prior art, when using common wrench demounting bolt or polygonal hook bolt, often because bolt head is capped, or screw thread and institute's securing objects loose contact, cause taking off securing member and become difficult.In order to address this problem, generally adopt the magnetic instrument of band at present, but being with magnetic instrument magnetic limited strength, being difficult to effectively adsorb securing member thus help it to take out.In addition, when securing members such as construction bolt nuts, if having bar or gap between securing member and institute's securing objects, then can not tight a bolt, cause fastening effect bad.
Utility model content
Technical problem to be solved in the utility model is that solving existing instrument is difficult to effectively adsorb securing member, can not the technical deficiency of effective fishbolt, there is provided a kind of structure simple, can fishbolt head, there is not gap between securing member and institute's securing objects when making securing member mount and dismount convenient and reliable, construction bolt or nut, to tight a bolt, spanner that fastening effect is good.
Technical problem to be solved in the utility model realizes by the following technical solutions:
Can the spanner of fishbolt head, comprise handle of a knife, be arranged at the handle at handle of a knife rear portion, be arranged at handle of a knife front end in the middle of keyhole and be positioned at the magnet of keyhole inside; Described handle of a knife front end is provided with clamping device, and described clamping device comprises groove, two slide rails and clamping bar, and described groove is located at handle of a knife front end, extending longitudinally along handle of a knife; The both sides of groove inner wall are located at respectively by two slide rails; Described clamping bar is located at outside groove, clamping bar front end is provided with chamfering, rear end is provided with barb, middle part be provided with to magnet direction protrude raised, circular hole is provided with in projection, described chamfering is the hook-shaped protrusion protruded to handle of a knife central axial direction, and described barb is the hook-shaped protrusion to protruding away from handle of a knife central axial direction; Circular hole in clamping bar projection is provided with columniform slide bar, and slide bar is stuck in the slide rail of corresponding recesses; From the groove second half section, handle of a knife caves inward gradually backward and forms pressure holding groove, be provided with spring in pressure holding groove, spring is located at inside clamping bar, is connected with handle of a knife by fixed leg, be provided with draw-in groove in the handle of a knife at spring rear, the size and shape of draw-in groove and the size and shape of barb match.
The effect of described slide bar is fixed in the groove of handle of a knife by clamping bar; Described clamping bar can be retreated with sliding bar and be snapped in draw-in groove by afterbody barb and be fixed on handle of a knife, can rotate, chamfering is opened when chamfering stretches out slide rail around slide bar; After described chamfering is opened, stop pressing clamping bar clamping bar can be made to recover the state of chamfering to inside fastening by spring action.During demounting bolt, first press clamping bar rear end, now chamfering is opened, and keyhole is aimed at bolt head, and front pushing away makes it be adsorbed in inner magnet; Unclamp clamping bar, under the action of the spring, chamfering sets back and clamping bolt head; Now by handle, external force is applied to it, handle is rotated around handle of a knife central axis, just can twist bolt, exert oneself backward simultaneously, it can be taken out from followed closely object; After taking-up, again pressing clamping bar can take off bolt from the utility model.The utility model is by the spring that arranges in the chamfering that arranges on clamping bar, pressure holding groove, the magnet arranging keyhole and arrange in keyhole inside in the middle of handle of a knife front end, can the effective securing member such as fishbolt, to outward winding easily the bolt taking off and skidded by the bolt covered or screw thread, make disassembling section become simple.The draw-in groove matched with barb size shape is provided with in handle of a knife again due to spring rear of the present utility model, can barb be stuck in draw-in groove, effectively prevent obstruction and the interference of chamfering during construction bolt, make gapless between bolt head and securing member, can tight a bolt when construction bolt.
Further, the quantity of described clamping device is two, and symmetrical relative to handle of a knife central axis.Its advantage is convenient to firmly, securing member stressed more even, and disassembling section is convenient.
Further, described handle and handle of a knife are hinged by jointed shaft, and the quantity of handle is two, and two handles are symmetrical relative to handle of a knife central axis, and in use procedure, handle and handle of a knife hinged place can rotate around jointed shaft.
Further, the shape of described keyhole and the shape of bolt head that matches with keyhole are regular polygon.
Compared with existing spanner, the utility model has following outstanding advantage and technique effect:
1) can outward winding easily and take off the bolt that bolt head skidded by the bolt covered or screw thread;
2) chamfering of clamping bar front end can be retracted when tighting a bolt, prevent chamfering from hindering operation.
