Abstract
The utility model discloses a slow -witted single lug adjustable spanner, 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, it is equipped with the lug of triangle -shaped or polygon mat column structure to stay the medial surface of pulling the lip, the medial surface that the lip was pulled in the activity is equipped with counter bore or recess, stay pull the lip medial surface with form reentrant angle between the lug. The beneficial effects of the utility model are that: the utility model discloses more can firmly twist nut or bolt centre gripping and can not damage the edges and corners of nut or bolt than traditional adjustable spanner.
Description
Technical field
The utility model relates to a kind of spanner, particularly relates to a kind of slow-witted single projection 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 slow-witted single projection 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 slow-witted single projection 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; Describedly stay the projection that the medial surface pulling lip is provided with triangle or polygon block structure, the medial surface of described Flexible spanner lip is provided with counterbore or groove; Described stay to pull between lip medial surface and described projection form re-entrant angle.
Described projection is located at describedly stays the middle part of pulling lip medial surface.
Described projection is located at describedly stays the avris pulling lip medial surface.
The side of described Flexible spanner lip is provided with groove.
When described Flexible spanner lip is pulled described projection when lip is drawn close can be inserted in counterbore on described Flexible spanner lip or groove to described being stayed.
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: nut or bolt firm grip more can carry out turning than traditional monkey wrench and the corner angle of nut or bolt can not be damaged by the utility model.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, 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 6, stays and pulls the front end that lip 3 and Flexible spanner lip 4 are disposed in parallel in driving end 2; Stay the projection 31 that the medial surface pulling lip 3 is provided with triangle or polygon block structure, stay to pull between lip 3 medial surface and projection 31 and form re-entrant angle 10; The inner side of Flexible spanner lip 4 offers counterbore or groove.
Projection 31 is located at describedly stays the middle part of pulling lip 3 medial surface.
Projection 31 is located at describedly stays the avris pulling lip 3 medial surface.
The side of Flexible spanner lip 4 is provided with groove.
When Flexible spanner lip 4 is pulled projection 31 when lip 3 is drawn close can be inserted in counterbore on inside Flexible spanner lip 4 or groove to being stayed.
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 6 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 10, 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 is pulled between lip 3 and projection 31 and formed re-entrant angle 10.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 7 outer is with three limits and contacts with the utility model embodiment and stressed during the utility model embodiment grip bolt, thus the corner angle of bolt 7 more can not damage because of loosening skidding when turning bolt 7 by the utility model embodiment by bolt 7 firm grip.
