Abstract
The utility model relates to a nut spanner, which belongs to the technical field of a hardware tool. The spanner comprises a movable spanner head, a spanner handle body, and a fixed spanner head fixed on the spanner handle body. The utility model also comprises a pull rod, a compressed spring, and a kick crank. The back part of the movable spanner head is hinged with the fixed spanner head. A spanner opening in a parrot mouth shape is formed. The middle back part of the movable spanner head is hinged with one end of the pull rod. The other end of the pull rod is inserted inside the spanner handle body, and is connected with one end of the kick crank and the compressed spring in a pin mode. The other end of the compressed spring is fixed inside the spanner handle body. The kick crank is engaged with the spanner handle body through a sliding mechanism. When the utility model is used, the pull rod can press the compressed spring so long as the kick crank is moved backwards, and the movable spanner head can be opened. After a nut is clamped inside the spanner opening in a parrot mouth shape, which is formed by the movable spanner head and the fixed spanner head, the kick crank can be loosed. The compressed spring automatically causes the movable spanner head to generate a closed trend when the compressed spring is reset, and thereby, the nut can be clamped. The utility model has the advantages of easy use and reliable clamping and torsion, which is an ideal substitute product for the existing same type tool.
Description
Technical field
The utility model relates to a kind of nut spanner, especially a kind ofly can regulate the nut spanner of pulling mouthful opening degree, belongs to the hardware ﹠ tools technical field.
Background technology
Nut spanner claims adjustable wrench again, is the hardware ﹠ tools of using always.Existing nut spanner as shown in Figure 1, mainly by movable jaw 1, handle body 2, fixedly spanner 3, adjusting screw(rod) 4 are formed, wherein fixedly spanner 3 is usually made an integral body with handle body 2, and a side of movable jaw 1 is shaped on partial screw threads, be contained in the chute of fixing spanner 3, with adjusting screw(rod) 4 engagements.During use,, movable jaw 1 is moved in the chute of fixing spanner 3, thereby regulate movable jaw 1 and the fixing opening degree between the spanner 3, clamp calorie requirement with the nut that adapts to different size by screwing adjusting screw(rod) 4.The problem that this existing nut spanner exists is to screw adjusting screw(rod) 4, can only make the opening degree of pulling mouthful become big gradually or diminishes, and it is convenient inadequately therefore to regulate, and especially uses all the more so in the more occasion of nut specification.
Summary of the invention
The purpose of this utility model is: at the problem that prior art exists, proposes a kind of can conveniently regulate and clamp block reliable self-regulated nut spanner.
In order to reach above purpose, self-regulated nut spanner of the present utility model comprises movable jaw, handle body and is fixed on fixedly spanner on the handle body, also comprise pull bar, stage clip and snap close, the rear portion of movable jaw and fixedly spanner is hinged forms parrot mouth shape and pulls mouth, and the postmedian of movable jaw and pull bar one end are hinged, the other end of pull bar inserts in the handle body, and with an end pin joint of snap close and stage clip, the other end of stage clip is fixed in the handle body, snap close is connected with handle body by slipping mechanism.
During use, move snap close after needing only, pull bar gets final product compression press spring, movable jaw is opened, when nut be stuck in movable jaw and in fixedly the parrot mouth shape that forms of spanner is pulled mouthful after, unclamp snap close, automatically make movable jaw produce closed trend when stage clip resets, thereby nut is clamped.
Be not difficult to find out that the utility model has made things convenient for many by the mode of screwing adjusting than prior art, and folder turn round reliable, can slippage.Therefore will become the desirable substitute products of existing similar tools.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of existing nut spanner.
Fig. 2 is the structural representation of the utility model embodiment one.
The specific embodiment
Embodiment one
The self-regulated nut spanner of present embodiment as shown in Figure 2, mainly by movable jaw 4, handle body 2, fixedly spanner 13, pull bar 7, stage clip 9 and snap close 10 are formed.Movable jaw 4 is c-shaped, and it is hook-shaped that its front end is made the about 120 ° of obtuse angles that are fit to block hex nut, and its rear portion and fixedly spanner 13 is hinged by bearing pin 5 forms parrot mouth shape and pulls mouth.The postmedian of movable jaw 4 is hinged with the front end of pull bar 7 by pin 15, and pin 15 is vertical substantially with handle body 2 with the line of bearing pin 5.Insert in the handle body 2 rear end of pull bar 7, and with the front end pin joint of snap close 10 and stage clip 9.The rear end of stage clip 9 is fixed in the handle body 2, and snap close 10 is sleeved on outside the handle body 2, forms moving sets with handle body 2.Handle body 2 rear ends stud with is convenient to grip flexible taper knob 11.
During use, four refer to hold taper knob 11, suitably dial backward with thumb as required and move snap close 10, and pull bar 7 is promptly affected compression press spring 9, makes movable jaw 4 open up into the size positions that is fit to block nut.Nut be sandwiched in parrot mouth shape that movable jaw 4 and fixing spanner 13 form pull mouthful in after, unclamp snap close 10, stage clip 9 automatically resets, and makes movable jaw 4 produce closed clamping trend.When application of force switching handle body 2, because pin 15 is vertical substantially with handle body 2 with the line of bearing pin 5, so movable jaw 4 self-lockings, nut is firmly clamped, rotate to desired location as required until nut.
Experiment showed, that present embodiment does not need artificial adjusting, it is handy, very convenient to use, and can effectively improve operating efficiencies such as assembling, maintenance.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
