Abstract
The utility model discloses a formula that staggers 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, stay the staying of massive structure that the medial surface of pulling the lip was equipped with the off centre line and pull the lip lug, the lip lug is pulled in the activity that the movable medial surface of pulling the lip was equipped with the massive structure of off centre line. The beneficial effects of the utility model are that: the utility model discloses stay pull the lip medial surface and stay pull between the lip lug reentrant angle that forms and activity pull lip medial surface and activity pull the reentrant angle who forms between the lip lug compare traditional adjustable spanner 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 staggered 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 staggered 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 staggered 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; The described medial surface pulling lip of staying is provided with staying of the shape block structure of disalignment and pulls lip projection, and the medial surface of described Flexible spanner lip is provided with the Flexible spanner lip projection of the block structure of disalignment; Described stay pull lip medial surface and described stay to pull between lip projection form re-entrant angle; Re-entrant angle is formed between described Flexible spanner lip medial surface and described Flexible spanner lip projection; The described thickness pulling lip projection of staying is less than and describedly stays the thickness pulling lip, and the thickness of described Flexible spanner lip projection is less than the thickness of described Flexible spanner lip.
Described staying is pulled lip projection and describedly stays that to pull lip be overall structure, and described Flexible spanner lip projection and described Flexible spanner lip are overall structure.
The leading flank of described Flexible spanner lip offers groove, and the described trailing flank pulling lip of staying offers groove; When described Flexible spanner lip and described staying are pulled described Flexible spanner lip projection when lip is drawn close and extend into and describedly stay in the groove pulled on lip trailing flank; When described Flexible spanner lip and described staying are pulled described staying when lip is drawn close and pulled in groove that lip projection extend on described Flexible spanner lip leading flank.
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 utility model is stayed to pull lip medial surface and stay the re-entrant angle formed between re-entrant angle and Flexible spanner lip medial surface and Flexible spanner lip projection pulled and formed between lip projection and more nut or bolt firm grip can be carried out turning than traditional monkey wrench and the corner angle of nut or bolt can not be damaged.

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 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 medial surface pulling lip 3 to be provided with staying of the block structure of disalignment and to pull lip projection 31, the medial surface of Flexible spanner lip 4 is provided with the Flexible spanner lip projection 41 of the block structure of disalignment; Stay to pull lip 3 medial surface and stay to pull between lip projection 31 and form re-entrant angle 10; Re-entrant angle 10 is formed between Flexible spanner lip 4 medial surface and Flexible spanner lip projection 41.
Stay the thickness pulling lip projection 31 and be less than the thickness of staying and pulling lip 3, the thickness of Flexible spanner lip projection 41 is less than the thickness of Flexible spanner lip 4;
Stay to pull lip projection 31 and stay and pull lip 3 for overall structure, Flexible spanner lip projection 41 and Flexible spanner lip 4 are overall structure.
The leading flank of Flexible spanner lip 4 offers groove, stays the trailing flank pulling lip 3 and offers groove; When Flexible spanner lip 4 is pulled Flexible spanner lip projection 41 when lip 3 is drawn close and extend in the groove of staying and pulling on lip 3 trailing flank with staying; When Flexible spanner lip 4 is pulled in groove that lip projection 31 extend on Flexible spanner lip 4 leading flank with staying to pull to stay when lip 3 is drawn close.
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 8, the difference of the utility model embodiment and traditional monkey wrench is:
Traditional activity spanner to stay the inner side of pulling lip and Flexible spanner lip be straight structure, and staying in embodiment of the present utility model pulls lip 3 and stay to pull and to define re-entrant angle 10 between lip projection 31 and define re-entrant angle 10 between Flexible spanner lip 4 and Flexible spanner lip projection 41.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 four limits (being respectively the right and left and left lower side and limit, bottom right) 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.
