Abstract
The utility model discloses a re -entrant angle adjustable spanner that keeps silent, its structure include handle, wrench end, stay pull the lip, lip, worm wheel and pivot are pulled in the activity, stay pull the lip with the activity is pulled the lip and is set up side by side the front end of wrench end, stay and be equipped with the re -entrant angle on the medial surface of pulling the lip the activity is pulled and is equipped with the re -entrant angle on the inboard of lip. The beneficial effects of the utility model are that: the activity that has a re -entrant angle pull the lip with stay pull the lip than traditional adjustable spanner's activity pull the lip with stay pull the lip more can with the nut or the bolt centre gripping firmly be twisted and can not be with the edges and corners damage of nut or bolt.
Description
Technical field
The utility model relates to a kind of spanner, particularly relates to a kind of re-entrant angle jaw monkey wrench.
Background technology
As depicted in figs. 1 and 2, the inner side of the jaw of traditional monkey wrench is straight structure, and the shortcoming of this spanner is that the contact surface of jaw and screw or nut only has two faces thus easily causes the corner angle of nut to damage rounding.
Utility model content
Problem to be solved in the utility model is to provide a kind of re-entrant angle jaw monkey wrench, and the stress surface of its jaw and nut in the process of stubborn nut has four faces thus the corner angle of nut can not be damaged.
In order to overcome the above problems, the technical solution of the utility model is as follows:
A kind of re-entrant angle jaw monkey wrench, its structure comprises handle, driving end, stays and pull lip, Flexible spanner lip, worm gear and pivot pin, and described staying pulls the front end that lip and described Flexible spanner lip are disposed in parallel in described driving end; Described stay pull lip medial surface on be provided with re-entrant angle, the inner side of described Flexible spanner lip is provided with re-entrant angle.Described handle, described driving end, described staying pull that lip, described Flexible spanner lip, textural association mode between described worm gear and described pivot pin are similar to the textural association mode of traditional monkey wrench just not to be set forth at this for prior art.
The beneficial effects of the utility model are: the Flexible spanner lip and staying with re-entrant angle is pulled lip and pulled lip than the Flexible spanner lip of traditional monkey wrench and staying and more nut or bolt firm grip can be carried out turning and the corner angle of nut or bolt can not be damaged.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional monkey wrench.
Structural representation when Fig. 2 is Fig. 1 grip bolt.
Fig. 3 is the structural representation of the utility model embodiment.
Structural representation when Fig. 4 is Fig. 3 grip bolt.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 3 and Figure 4, its structure of the utility model comprises handle 1, driving end 2, stays and pull lip 3, Flexible spanner lip 4, worm gear 5 and pivot pin, stays and pulls the front end that lip 3 and Flexible spanner lip 4 are disposed in parallel in driving end 2; Be provided with re-entrant angle 20 staying on the medial surface pulling lip 3, the inner side of Flexible spanner lip 4 is provided with re-entrant angle 20.Handle 1, driving end 2, stay and pull that lip 3, Flexible spanner lip 4, textural association mode between worm gear 5 and pivot pin are similar to the textural association mode of traditional monkey wrench just not to be set forth at this for prior art.
As shown in Figures 1 to 4, the difference of the utility model embodiment and traditional monkey wrench is:
The inner side of pulling lip and Flexible spanner lip of staying of traditional activity spanner is straight structure, and staying in embodiment of the present utility model pull lip 3 and Flexible spanner lip 4 inner side on be all provided with re-entrant angle 20.The periphery of bolt is hexagonal structure, hexagonal bolt clip is held in six limits staying bolt when pulling between lip and Flexible spanner lip and only has two limits to contact with monkey wrench and stressed by traditional monkey wrench, and bolt 6 outer is with four limits and contacts with the utility model embodiment and stressed during the utility model embodiment grip bolt 6, thus the corner angle of bolt 6 more can not damage because of loosening skidding when turning bolt 6 by the utility model embodiment by bolt 6 firm grip.
