Abstract
A kind of band hook spanner, the magnet of relate to hand-operated tools technical field, comprise main body handle of a knife, the be arranged at middle keyhole in handle of a knife front end and its inside; The side of described handle of a knife front end is provided with hook, and described hook comprises the chamfering being arranged at hook front end, and described chamfering is the projection protruded to handle of a knife central axial direction; Jointed shaft on the middle part of hook and handle of a knife fixed leg is hinged.The utility model solves existing instrument and is difficult to effective fixation fastener, effectively can not dismantle and/or technical deficiency that complex process cost is high, simply be improved by spanner, a kind of band hook spanner is provided, can light fixation fastener, dismantle effective and preparation technology simple, with low cost.
Description
Technical field
The utility model relates to hand-operated tools technical field, specifically a kind of spanner with hook.
Background technology
In prior art; when using common wrench dismounting nut or polygonal hook bolt; because bolt head is often capped, or screw thread and institute's securing objects usually there will be the phenomenon of loose contact, cause taking off securing member and become difficulty; in order to address this problem; someone devise some complicated machineries even electric device dismantle, but due to its complex process, with high costs; and dismounting weak effect, can not meet the needs of production.
Utility model content
Technical problem to be solved in the utility model is that solving existing instrument is difficult to effective fixation fastener, can not effectively dismantle and/or technical deficiency that complex process cost is high, spanner is simply improved, a kind of band hook spanner is provided, can light fixation fastener, dismantle effective and preparation technology simple, with low cost.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of band hook spanner, comprises main body handle of a knife, is arranged at the magnet of the middle keyhole in handle of a knife front end and its inside; The side of described handle of a knife front end is provided with hook, and described hook comprises the chamfering being arranged at hook front end, and described chamfering is the projection protruded to handle of a knife central axial direction; Jointed shaft on the middle part of hook and handle of a knife fixed leg is hinged.
Further, the size and shape of the shape of described keyhole and size and fixture (as bolt etc.) matches, and such as when fixture is regular polygon, keyhole is also the regular polygon of corresponding size.
Preferably, described handle of a knife is stainless steel, and described hook also can be stainless steel, to extend service life of the present utility model.
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) because hook of the present utility model can jointed shaft on fixed leg rotate, chamfering is opened or restores to the original state, when tight a bolt or nut time the chamfering of hook front end can be opened, and then prevent the operation of chamfering obstruction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that A of the present utility model is to schematic diagram;
In figure: 1 handle of a knife; 2 hooks; 21 chamferings; 3 fixed legs; 31 jointed shafts; 4 keyholes; 41 magnet; 5 bolts.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment and diagram, setting forth the utility model further.
A kind of band hook spanner, comprises main body handle of a knife 1, is arranged at the magnet 41 of the middle keyhole 4 in handle of a knife 1 front end and its inside; Handle of a knife 1 front end is provided with hook 2, and described hook 2 comprises the chamfering 21 being arranged at hook 2 leading portion, described chamfering is the projection protruded to handle of a knife central axial direction; Jointed shaft 31 on the middle part of hook 2 and handle of a knife 1 fixed leg 3 is hinged.
Described keyhole 4 shape can be set to as regular polygon, matches with securing members such as multiple bolts.
Described hook 2 can rotate by the jointed shaft 31 on fixed leg, and chamfering is opened.
In the present embodiment, described handle of a knife is stainless steel, and described hook also can be stainless steel, to extend service life of the present utility model.
The method of demounting bolt:
First press hook 2 rear end, as depicted in figs. 1 and 2, Leading end chamfer 21 is opened, keyhole 4 is aimed at bolt 5, front pushing away makes it be adsorbed in inner magnet 41; Unclamp hook 2, chamfering 21 is set back and clamping bolt 5; External force is applied to handle of a knife 1, handle of a knife 1 is rotated around central axis, just can twist bolt 5, exert oneself backward simultaneously, it can be taken out from followed closely object; After taking-up, again pressing hook 2 can take off bolt 5 from the utility model.
The method of construction bolt:
Pressing hook 2 rear end, makes the chamfering 21 of hook 2 open; Bolt 5 is aimed at keyhole 4 and is adsorbed in after on magnet 41 wherein; External force is applied to handle of a knife 1, handle of a knife 1 is rotated around central axis, can construction bolt 5.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
