Abstract
The invention discloses a fixed-single-projection movable wrench which comprises a handle, a wrench head, a fixed wrench lip, a movable wrench lip, a worm gear and a pin. The fixed wrench lip and the movable wrench lip are parallelly arranged at the front end of the wrench head. The inside surface of the fixed wrench lip is provided with a projection which has a triangular or polygonal block-shaped structure. The inside surface of the movable wrench lip is provided with a sink hole or a groove. A concave corner is formed between the inside surface of the fixed wrench lip and the projection. The fixed-single-projection movable wrench is beneficial in that the fixed-single-projection movable wrench can realize higher clamping firmness of a screw cap or a bolt than that of a traditional movable wrench for screwing without edge damage of the screw cap or the bolt.
Description
Technical field
The present invention relates to a kind of spanner, particularly relate 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.
Summary of the invention
Problem to be solved by this invention 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, technical scheme of the present invention 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 invention has the beneficial effects as follows: 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 present invention.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, its structure of the present invention 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 embodiment of the present invention 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 on embodiments of the invention 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 embodiment of the present invention and stressed during embodiment of the present invention grip bolt, thus the corner angle of bolt 7 more can not damage because of loosening skidding when turning bolt 7 by the embodiment of the present invention by bolt 7 firm grip.
