Abstract
The invention relates to a guide rail built-in fast-clamping spanner, which comprises a handle, a fixed clamp body, a movable clamp body and a pushing button used for pushing the movable clamp body to move, which are connected into a whole. The fixed clamp body is provided with a step-shaped sliding hole through which the movable clamp body can slide, a built-in guide rail of the movable clamp body is formed on the periphery of the sliding hole, and the movable clamp body is embedded in the step-shaped sliding hole of the fixed clamp body and can slide along the built-in guide rail; and a piece of rectangular tooth board is embedded at the connecting end of the handle and the fixed clamp body, and the tooth board forms a bottom board of the step-shaped sliding hole. A contacting end face of the movable clamp body and the bottom board can be divided into three sections in the movable clamp body moving direction: the inner section is a flat-board section, the middle section is a groove section, and the outer section is a rack section. The guide rail built-in fast-clamping spanner has the advantages of simple structure, high adjusting speed and single hand operation, and the movable clamp body can form a locking state when clamping workpieces, without looseness.
Description
Technical field
The present invention relates to a kind of hand-held tool that is used to screw parts such as nut, relate in particular to a kind of quick-clip wrench with built-in guide-rail.
Background technology
The adjusting spanner of prior art generally comprises handle and is connected fixed caliper, moving caliper and a worm-and-wheel gear of handle front end, the motion that worm-and-wheel gear is used for controlling moving caliper is to reach different opening degrees, and the user needs spended time to remove to rotate worm gear; Perhaps in order to make the close easier of jaw, use the adjustable spanner of motorized, this spanner moves with the quickening caliper by battery-operated motor and regulates the opening and closing of jaw, has saved the time of regulating jaw.More than two kinds of instruments all need some Mechanical Driven or transmission to realize regulatory function.Or complex structure, or governing speed is slow.Can not satisfy demand simple in structure, that governing speed is fast simultaneously.
Summary of the invention
Purpose of the present invention is exactly in order to solve the problem that above-mentioned prior art exists, and a kind of simple in structure, quick-clip wrench with built-in guide-rail that governing speed is fast is provided.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of quick-clip wrench with built-in guide-rail, comprise handle and fixed caliper, the moving caliper that fuses and be used to promote the push button that moving caliper moves, on fixed caliper, be provided with the step slide opening that slides for moving caliper, the periphery of slide opening forms the built-in guide rail of moving caliper, and moving caliper is inlaid in the step slide opening of fixed caliper and can slides along built-in guide rail; Be characterized in: described handle is embedded with a block length bar shaped tooth plate at the link of itself and fixed caliper, this tooth plate forms the base plate of step slide opening, the end face that contacts with above-mentioned base plate of described moving caliper is divided into three sections along the direction of motion of moving caliper, inner segment is a flat plate section, the stage casing is the groove section, and outer section is a rack segments.
The outer surface of described rack segments and the outer surface of flat plate section are in same plane.
The inclined to one side outer fix in the bottom of described push button and moving caliper is fixedly linked.
Described strip tooth plate and the mutual adaptive and engageable formation snap close that links to each other of the rack segments on the moving caliper.
Quick-clip wrench with built-in guide-rail of the present invention is simple in structure, governing speed is fast, can one-handed performance, and moving caliper forms locking during clamping work pieces, can not become flexible.

Fig. 2 is the sectional structure schematic diagram of quick-clip wrench with built-in guide-rail of the present invention;
Fig. 3 is the perspective view of the moving caliper among the present invention;
Fig. 4 is the perspective view of the strip tooth plate among the present invention.
The specific embodiment
Referring to Fig. 1, cooperate referring to Fig. 2, Fig. 3, Fig. 4, quick-clip wrench with built-in guide-rail of the present invention comprises handle 1, fixed caliper 2, moving caliper 3 and push button 4.Handle 1 and fixed caliper 2 fuse.Be provided with the step slide opening 21 that slides for moving caliper 3 on fixed caliper 2, the periphery of slide opening forms the built-in guide rail 22 of moving caliper, is provided with the chute 23 of connection slide opening 21 in a side of fixed caliper.Moving caliper 3 is inlaid in step slide opening 21 interior can the sliding along built-in guide rail 22 of fixed caliper.Handle 1 is embedded with a block length bar shaped tooth plate 5 at the link of itself and fixed caliper 2, this tooth plate forms the base plate of step slide opening 21, the end face that contacts with above-mentioned base plate 5 of moving caliper 3 is divided into three sections along the direction of motion of moving caliper, inner segment 31 is a flat plate section, stage casing 32 is the groove section, and outer section 33 is a rack segments; The outer surface of the outer surface of rack segments 33 and flat plate section 31 is in same plane; The rack segments 33 mutual adaptive and engageable formation snap closes that link to each other on strip tooth plate 5 and the moving caliper.Push button 4 passes with the inclined to one side outer fix in moving caliper 3 bottoms from the chute 23 of fixed caliper and is fixedly linked, shown in Fig. 3 34 be the connecting hole that is arranged on the moving caliper 3.Push button 4 can promote outside the moving of moving caliper opens jaw.
The present invention simplifies the close program of moving caliper by reducing mechanical transmission mechanism, simultaneously, has kept the adjustable feature of instrument and a kind of mode of quick adjustment is provided.
The present invention is provided with a built-in guide rail that allows caliper slide in the place that is away from the caliper working region, the self-locking feature by caliper realizes above purpose.
Quick-clip wrench with built-in guide-rail of the present invention is when being in non-working condition, and spanner is kept closed under the effect of spring force, and when needing to use, the user only needs can clamp workpiece by promoting button to open jaw.Because the inclined to one side outer fix in bottom of push button and moving caliper is fixedly linked, when outwards enforcing button, impetus is in the inclined to one side outer fix in the bottom of moving caliper, and this will make outer section 33 of moving caliper to be that rack segments lifts a little, realizes that smoothly moving caliper outwards moves.When clamping workpiece and exert oneself, because impetus is at the jaw position, and the direction of the power that is subjected to of moving caliper jaw outwardly, and at this moment outer section 33 of moving caliper is that rack segments can press down a little to link to each other to form with 5 engagements of strip tooth plate and locks, make that moving caliper is unlikely to be moved, help operation.After shedding workpiece, spanner can recover closure state again immediately under the effect of spring force, operates extremely simply quick and convenient.
