Description

Adjustable spanner

Technical Field

The utility model relates to a mechanical maintenance tool especially relates to an adjustable spanner.

Technical Field

In practical application, the dead wrench has a simple structure, and can bear larger force although the size of the dead wrench cannot be adjusted, so that the dead wrench is widely applied; the adjustable wrench has a wide application size range, but the nut is not clamped tightly by the wrench due to low precision of the adjusting nut, so that the nut is easy to slip and buckle, and the adjustable wrench cannot be used for bolts with large stress. The advantages and disadvantages of the conventional wrench can not be summarized, and the requirements of bearing larger force and wider size can not be met at the same time. Therefore, there is a need for an adjustable wrench, which has the advantages of simple operation, rapid adjustment, wide application range, large bearing load, etc.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5 and fig. 6, the present invention provides an adjustable wrench, which includes a threaded rod 1, a wrench head 2, a bolt 6, and a nut 701. The thread push rod comprises a threaded push rod 1 and is characterized by further comprising a large V-shaped slide block 4, a small V-shaped slide block 5, a convex pressing plate 3 and a stop pin 7, wherein a protrusion 101 is arranged at the end of the threaded push rod 1; the outer side of the upper part of the wrench head 2 is semi-cylindrical, and the inner side of the wrench head is two planes with an included angle of 120 degrees; the lower part of the wrench head 2 is provided with a threaded hole 201; the convex pressing plate 3 is provided with two symmetrical through holes 301 and a protrusion 302; the large V-shaped sliding block 4 is hollow and provided with a concave sliding groove, and the lower part of the large V-shaped sliding block is provided with a groove 401 and a threaded hole 402; the small V-shaped sliding block 5 is provided with a through hole 501 and a convex structure; the lower end of the stop pin 7 is provided with threads, and the middle part of the stop pin is provided with an irregular cylinder.

The thread 102 of the thread push rod is matched with the thread hole 201 at the lower part of the wrench head 2, and the relative position of the thread push rod and the wrench head is adjusted through the thread push rod 1. The end part protrusion 101 of the threaded push rod is connected with the lower groove 401 of the large V-shaped sliding block 4 through the convex pressing plate 3 and can rotate relatively.
