Description
Technical field
The utility model relates to a kind of instrument, particularly a kind of spanner, is mainly used in the torsion to various bolt or nut.
Background technology
Existing spanner comprises forked type spanner or the monkey wrench of fixed, and the openings of sizes of forked type spanner is fixing, needs to be equipped with plurality of specifications, to be applicable to bolt or the nut of specification of all sizes.The structure of monkey spanner be have one with pinch bar be integrative-structure fixedly pull pawl, with fixedly pull the Flexible spanner pawl that pawl matches and can move under the driving of handwheel, with adjustment and the relative distance of fixedly pulling pawl, to be applicable to bolt or the nut of specification of all sizes.Existing spanner is casting structure, needs to utilize die casting and molding, in addition the machined of postorder or assembling, and cost is higher, wastes time and energy.In use for bolt or the nut of different size, if also need when utilizing forked type spanner to select in numerous spanners, cumbersome; If need when utilizing monkey wrench to rotate handwheel to regulate the size of opening, adjust that improper to there will be opening little, can not, together outside the bolt needing rotation or nut, also need again to adjust; Also there will be the larger situation of opening after adjustment, during rotation, there will be slip phenomenon.
Summary of the invention
The purpose of this utility model is to provide the spanner that a kind of structure is simple, do not need to select or adjust wrench opening, easy to use, time saving and energy saving, low cost of manufacture when being applicable to plurality of specifications, rotating bolt or nut, overcomes the deficiencies in the prior art.
Spanner of the present utility model, comprises the middle frame being positioned at middle part, is fixed with the first side plate opposite side is fixed with the second side plate in the side of middle frame;
Be positioned at end and gripped interior lining panel between the first side plate and the second side plate; The position, termination of the first side plate, the second side plate and interior lining panel forms fixed engagement pawl; One end of engagement in rotation pawl by rotating shaft and hook-type between inner side first side plate and the second side plate of interior lining panel is rotationally connected, and the medial surface of engagement in rotation pawl becomes wrench grasp opening with described fixed engagement claw type;
The end of the first side plate, the second side plate, interior lining panel and the medial surface of engagement in rotation pawl are distributed with laterally anti-skidding rib;
Be positioned on middle frame in the inner side of rotating shaft and be fixedly connected with stage clip, the termination of stage clip is pressed on described engagement in rotation pawl.
Described wrench two-end structure is identical and be symmetrical arranged.
The first described side plate, the second side plate, interior lining panel and engagement in rotation pawl are at least double layer of metal plate and stack fixed-type.
Spanner of the present utility model, overall structure is simple, low cost of manufacture, the size artificially adjusting opening is not needed during use, engaged claw is rotated under the action of the spring before using, close with fixed engagement pawl, when engagement in rotation pawl is close to bolt or nut by operating personnel, can automatically open after engagement in rotation pawl is stressed, become wrench opening with fixed engagement claw type and mount outside bolt or nut, now rotating spanner, bolt or nut can be driven to rotate together, easy to operate, time saving and energy saving, the large I of opening changes automatically according to bolt or the peripheral radial dimension of nut.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is the structural representation after removal second side plate shown in Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2: 1 is middle frame, 2 is the first side plate, and 9 is the second side plate, and the first side plate 2 and the second side plate 9 are clamped in the both sides of middle frame 1 and are parallel to each other, and three can adopt rivet 12 or screw to be fixedly connected with, and make three parts fix as a whole.In order to ensure accurate positioning each other, be provided with boss 11 in the both sides of middle frame 1, boss 11 inserts in the hole matched with boss 11 on the first side plate 2 and the second side plate 9.
Between the first side plate 2 and the second side plate 9 and be positioned at end clamping and be fixed with interior lining panel 8 by fixed claw rivet 7; The position, termination of the first side plate 2, second side plate 9 and interior lining panel 8 forms the fixed engagement pawl of arc.
Be rotationally connected by rotating shaft 5 one end with the engagement in rotation pawl 6 of hook-type between inner side first side plate 2 and the second side plate 9 of interior lining panel 8, the medial surface of engagement in rotation pawl 6 becomes wrench grasp opening with fixed engagement claw type.
First side plate 2, second side plate 9, the end of interior lining panel 8 and the medial surface of engagement in rotation pawl 6 are distributed with laterally anti-skidding rib, prevent from sliding when wrenching bolt or nut.
Be positioned in the inner side of rotating shaft 5 on middle frame 1 and be fixedly connected with stage clip 4 by spring staple 3, the termination of stage clip 4 is pressed on engagement in rotation pawl 6, together with engagement in rotation pawl 6 is combined in fixed engagement dog clutch under elastic force effect at ordinary times.
Wrench two-end structure is identical and be symmetrical arranged, and in order to ensure that the spanner scope of application is larger, when spanner two-end structure is identical, specification can be made into size two kinds.
First side plate 2, second side plate 9, interior lining panel 8 and engagement in rotation pawl 6 are at least double layer of metal plate and stack fixed-type, its fixed form can be riveted joint or bonding mutually, rotate engaged claw 6 in the utility model to be riveted by engagement in rotation pawl rivet 10, the first side plate 2, second side plate 9, interior lining panel 8 are riveted by fixed claw rivet 7.
