Embodiment Construction

[0012] The present invention will be further described in detail through the embodiments below in conjunction with the accompanying drawings.

[0013] see figure 1 , This double-headed adjustable wrench comprising a wrench body 1, a nut-shaped opening and an opening adjusting device thereof, the nut-like opening is a through hole 2, 8 that is located at two ends of the vertical wrench body 1 and matches different nut shapes. There is a strip-shaped groove in the long axis of the pull body 1, and a movable strip is placed therein. The end shapes of the two ends of the movable strip match the shapes of the through-hole walls at both ends respectively, forming a complete through-hole wall. The present embodiment is hexagonal through hole 2,8 (certainly, through hole 2,8 also can be set to other shapes as required, such as pentagonal etc.), from figure 1 As can be seen in the figure, the four sides of the big mouth end are complete, and a part of the other two sides is formed by ...

Abstract

The present invention relates to a double-head adjustable spanner. It comprises spanner body, nut-like opening and opening-regulating device, etc. The nut-like opening is a through hole which is respectively set in each end of two ends of striaght spanner body and can be matched with different nut forms; in the middle length position of said spanner body an axial strip slot in which a movable strip component is set is cut, the form of end portion of two ends of the movable strip component can be matched with the form of through hole wall of its two ends so as to form complete through hole wall. The form of two through hole walls is hexagonal, and the form of end portion of one end of said movable strip component is made into 'V' form, and its another end form is made into 'M' form which respectively is a composition portion of said through hole wall. The opening regulating device is regulating wheel set in the middle of movable strip.

Description

technical field [0001] The invention belongs to a hardware tool, in particular to an adjustable wrench. Background technique [0002] Before the invention, the adjustable wrench has been widely used as a tool, and it has become an important part of hardware tools. The structure of existing adjustable wrench is generally made of wrench body, nut-shaped opening and its opening adjustment wheel. During use, according to the size of the nut, the opening adjustment wheel is adjusted to the matching operation to complete the work. However, the traditional adjustable wrench has deficiencies in actual application: there are only two working faces on the wrench opening and the nut wall is in contact with the force, so sometimes slipping occurs, which affects the operation; for the same size nut, the other The working part of the wrench is too large, and it is not suitable for use in some narrow places. Invention content: [0003] The object of the present invention is to provide ...
