Detailed Description

The present invention will be further explained with reference to the drawings and examples. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and therefore show only important constituent parts related to the present invention.

The traditional spanner utilizes the turbine pole to adjust, and efficiency is very slow.

The utility model relates to a quick adjusting wrench, which is based on the slow speed and low efficiency of the traditional wrench, changes the fixed jaw of the traditional wrench and the handle structure fixed with the fixed jaw into a whole, hollows the inside of the handle and makes the handle into an irregular geometric shape, so that the inside of the handle is a telescopic chute for adjusting the length; the movable jaw is fixedly connected with a telescopic rod, and the telescopic rod can not turn to dislocation by virtue of an irregular internal channel in the handle. The fixing clamping pieces fixedly connected to the upper surface of the telescopic rod are horizontally arranged, so that the traditional threads are changed, the length of the telescopic rod can be quickly adjusted in a telescopic mode, meanwhile, the fixing device is arranged outside the handle, and after the desired jaw width is quickly adjusted, one-step positioning can be achieved.

As shown in fig. 1 to 15, the utility model relates to a quick adjustment wrench includes fixed jaw 1 and with fixed jaw 1 fixed connection handle 3 as an organic whole, the inside of handle 3 is provided with flexible groove 4, for one be convenient for the installation and prevent that inside part warp and turn to, flexible groove 4's structure is middle big little structure in two (or other anomalous shape all can), inside hole can be circular also can be square, in this embodiment be circular, big circular upper and lower both ends respectively set up two bellied recesses in the middle, make internally mounted's part more steady, can not fall out the handle outside and combine inseparabler. In addition, a positioning groove 5 penetrating through the inner telescopic groove 4 is arranged in the transverse crossing direction above (or below) the handle 3, and shaft holes 6 are respectively arranged at the center positions of two sides of the positioning groove 6 and used for installing positioning wheels 9 of the positioning device.

The movable jaw 2 is fixedly connected to one end of the telescopic rod 7 and integrated with the telescopic rod 7, the telescopic rod 7 is in a size and a structure which are matched with the inside of the telescopic groove 4, the structure is also in a structure with a large middle and two small ends, the telescopic rod can be just inserted into the telescopic groove 4 to be matched, the middle part and the lower part of the telescopic rod are both in solid structures and are used for fixing more stably, the protruding part above the telescopic rod is a fixing clamping piece 8, and the size of the fixing clamping piece 8 is matched with the size of the groove above the telescopic groove 4; the fixing clamping pieces 8 above the telescopic rod 7 are a plurality of fixing clamping pieces 8 which are horizontally and uniformly arranged above the telescopic rod 7; and the fixing clip 8 above the telescopic rod 7 is overlapped and intersected with the positioning groove 5 of the handle 3 at the same time.
