Description

A kind of combination wrench
Technical field
The utility model belongs to wrench technical field of tools, especially a kind of combination wrench.
Background technique
Currently, it is many kinds of using existing spanner, such as fork spanner, adjustable wrench, box spanner, allen wrench, The spanner that screw uses suitable dimension must be corresponded to when use, it has not been convenient to.Though and improved part spanner heat have it is integrated Trend, but still operation can only be carried out for similar or similar shape nut, bolt, applicability nevertheless suffers from biggish office Limit.
Utility model content
The purpose of the utility model is to overcome providing in place of the deficiencies in the prior art, a kind of structure is simple, applicability is wide Combination wrench.
The utility model solves its technical problem and adopts the following technical solutions to achieve:
A kind of combination wrench, including pull body, sliding block, moving jaw, adjusting rod, ratchet mechanism and reset spring, wherein it pulls Body is a long handle, and one end is vertically fixed with a regular jaw, and pulling beside the regular jaw is provided with tooth socket, tooth on body position Slot and regular jaw are located at the upper and lower two sides for pulling body, are arranged at intervals with rack gear in tooth socket, be slidably matched peace on the rack gear Equipped with a sliding block, which is fixed with moving jaw, and ratchet structure is provided in sliding block and rack gear cooperates, the ratchet structure Upper installation reset spring, reset spring are fixedly mounted with adjusting rod, and adjusting rod is oblique to be pierced by from sliding block and its extended line and pull the bodily form It forms an angle, is provided with arc-shaped steel bead groove in the middle part of regular jaw and moving jaw, is embedded in each steel bead groove more A steel ball, the interior space mobile there are steel ball of steel bead groove.
Moreover, the ratchet structure includes ratchet and pawl, reset spring, one end of reset spring and spine are installed on pawl Pawl cooperation, the other end are fixedly mounted with by one end of fixed block and adjusting rod.
The advantages and positive effects of the utility model are as follows:
Combination wrench provided by the utility model can correspond to the torquing operations of most of screws, nut outer profile, by more A steel ball and the multiple point contacts of screw, nut outer profile realize multiple spot stress, are more uniformly stressed it, avoiding turning makes to occur It skids or deviates, can apply in the field of similar movement, applicability is wide.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the right side view of regular jaw structure in Fig. 1.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by specific embodiment, and following embodiment is only retouched The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of combination wrench, comprising: pull body 5, moving jaw 6, adjusting rod 4, ratchet mechanism and reset spring etc. several zero Part, wherein pulling body is a long handle, and one end is vertically fixed with a regular jaw 8, and pulling beside the regular jaw sets on body position It is equipped with tooth socket 1, tooth socket and regular jaw are located at the upper and lower two sides for pulling body, rack gear 2 are arranged at intervals in tooth socket, in the tooth Being slidably installed on item has a sliding block 3, which is fixed with moving jaw, is provided with ratchet structure and rack gear in sliding block Cooperation, which includes ratchet and pawl, installs reset spring on pawl.
One end of reset spring and click-fit, the other end are fixedly mounted with by one end of fixed block and adjusting rod, and adjusting rod is oblique To being pierced by from sliding block and its extended line forms an angle with the bodily form is pulled.It is rotated by adjusting rod adjustment gear;Moving jaw prolongs The handle for stretching out one column tooth socket of band cooperates with gear, adjusts moving up and down for moving jaw by adjusting rod: pressure adjusting rod, living Movable clamp port tightening;Adjusting rod is raised, moving jaw can move freely.
It is provided with arc-shaped steel bead groove 9 in the middle part of regular jaw and moving jaw, is embedded in each steel bead groove multiple Steel ball 7, relaxation arrangement, there are movable spaces;Since two jaws are embedded in mobilizable steel ball, the steel ball when clamping claw Four steel balls up and down in group withstand screw cap or nut, play the role of clamping.When unclamping adjusting rod, reset spring will be adjusted Initial position is returned on pole top.
In use, raising adjusting rod, moving jaw is adjusted to approximate location, constantly pressure adjusting rod, tightens jaw, it will Screw cap locking.After tightening or unclamping screw, adjustment bar is raised, jaw unclamps, and operation is completed.
Ratchet structure and relatively conventional with the mounting structure of reset spring, is not shown in the present embodiment.
Although disclosing the embodiments of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be with Understand: departing from the utility model and spirit and scope of the appended claims, various substitutions, changes and modifications are all can Can, therefore, the scope of the utility model is not limited to the embodiment and attached drawing disclosure of that.
