Abstract
The utility model discloses a bayonet lug adjustable spanner, its structure include handle, wrench end, stay pull the lip, lip, worm wheel and pivot are pulled in the activity, it is equipped with staying of massive structure and pulls the lip lug to stay the medial surface of pulling the lip, the lip lug is pulled in the activity that the movable medial surface of pulling the lip was equipped with the massive structure, stay pull the lip medial surface with it forms reentrant angle to stay to pull between the lip lug, the activity pull the lip medial surface with the activity is pulled and is formed reentrant angle between the lip lug 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 plug-in type 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 plug-in type 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 plug-in type 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 block structure and pulls lip projection, and the medial surface of described Flexible spanner lip is provided with the Flexible spanner lip projection of block structure; 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; Described Flexible spanner lip projection is provided with two, and two Flexible spanner lip projections are symmetricly set on inside described Flexible spanner lip side by side, and the space length between two Flexible spanner lip projections is greater than describedly stays the thickness pulling lip projection; Described staying is pulled lip projection and is arranged on and describedly stays the middle part of pulling inside lip; Counterbore is offered inside described Flexible spanner lip.
When described Flexible spanner lip is pulled described staying when lip is drawn close and pulled lip projection by the space between described two Flexible spanner lip projections to described staying and be inserted in the counterbore on inside 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 described both sides, front and back of pulling lip of staying offer groove respectively, when described Flexible spanner lip and described stay pull when lip is drawn close described in two Flexible spanner lip projections extend into described staying in the groove pulling lip both sides respectively.
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 block structure and to pull lip projection 31, the medial surface of Flexible spanner lip 4 is provided with the Flexible spanner lip projection 41 of block structure; 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; Flexible spanner lip projection 41 is provided with two, is symmetricly set on the inner side of Flexible spanner lip 4 before and after two Flexible spanner lip projections 41 side by side, and the space length between two Flexible spanner lip projections 41 is greater than the thickness of staying and pulling lip projection 31; Stay and pull lip projection 31 and be arranged on the middle part stayed and pull inside lip 3; The inner side of Flexible spanner lip 4 offers counterbore; When Flexible spanner lip 4 is pulled lip projection 31 by the space between two Flexible spanner lip projections 41 be inserted in the counterbore on inside Flexible spanner lip 4 to being stayed to pull to stay when lip 3 is drawn close.
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.
Stay the both sides, front and back of pulling lip 3 and offer groove respectively, when Flexible spanner lip 4 is pulled two Flexible spanner lip projections 41 when lip 3 is drawn close and extend into respectively to stay and pull in two grooves of lip 3 both sides with staying.
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.
