Problems solved by technology

The wrenches in the prior art are basically divided into two types, one is a fixed wrench with only a single type of wrench head, and this type of wrench can only operate on screws or screw rods of a fixed type
The other is a combination wrench capable of operating different types of screws or screw rods, but the existing combination wrench has the disadvantage of complicated wrench head replacement, and when the number of wrench heads is large, there is also the problem that the wrench heads are easy to lose, which is not conducive to Improve user satisfaction

Abstract

The invention provides a multifunctional spanner. The multifunctional spanner comprises a handle part; the multifunctional spanner is characterized in that an engagement hole is formed in the bottom surface of one end of the handle part; the multifunctional spanner further comprises a spanner head group which comprises at least two spanner heads different in size; an engagement column matched with the engagement hole in shape and size is arranged on the bottom surface of one end of each spanner head, while a fixing hole having the same shape and size with the engagement hole is formed in the bottom surface of the other end of each spanner head. A user can select the spanner head according to requirements and mount the detached spanner heads on other supporting arms, and therefore, the problem of easy loss of the spanner heads due to overmany spanner heads can be avoided.

Description

technical field [0001] The invention relates to a multifunctional wrench, in particular to a multifunctional wrench capable of operating different types of screws or screw rods. Background technique [0002] As an important tool, wrench plays an increasingly important role in people's life. The wrenches in the prior art are basically divided into two types, one is a fixed wrench with only a single type of wrench head, and this type of wrench can only operate on screws or screw rods of a fixed type. The other is a combination wrench capable of operating different types of screws or screw rods, but the existing combination wrench has the disadvantage of complicated wrench head replacement, and when the number of wrench heads is large, there is also the problem that the wrench heads are easy to lose, which is not conducive to Improve user satisfaction. Contents of the invention [0003] In view of this, it is necessary to provide a multifunctional wrench which is easy to re...
