Abstract
The invention discloses a kind of ladder 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 in the step structure with a re-entrant angle, the medial surface of described Flexible spanner lip is in the step structure with a re-entrant angle.The invention has the beneficial effects as follows: 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.
Description
Technical field
The present invention relates to a kind of spanner, particularly relate to a kind of ladder 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.
Summary of the invention
Problem to be solved by this invention is to provide a kind of ladder 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, technical scheme of the present invention is as follows:
A kind of ladder 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 in the step structure with a re-entrant angle, the medial surface of described Flexible spanner lip is in the step structure with a 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 invention has the beneficial effects as follows: 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 embodiment of the present invention.
Structural representation when Fig. 4 is Fig. 3 grip bolt.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 3 and Figure 4, 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 (51), stays and pulls the front end that lip 3 and Flexible spanner lip 4 are disposed in parallel in driving end 2; Stay pull lip 3 medial surface in the step structure with a re-entrant angle 20, the medial surface of Flexible spanner lip 4 is in the step structure with a 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 (51) 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 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 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 (being respectively the right and left and left lower side and limit, bottom right) and contacts with the embodiment of the present invention and stressed during embodiment of the present invention grip bolt 6, thus the corner angle of bolt 6 more can not damage because of loosening skidding when turning bolt 6 by the embodiment of the present invention by bolt 6 firm grip.
