Problems solved by technology

The structure of the wrenches used to screw the hexagonal screws or nuts is too fixed today, and some wrenches can only correspond to one size of hexagonal screws or nuts. When encountering unsuitable hexagonal screws or nuts, the wrench must be replaced to continue working; Although some wrenches can adjust the width of the bayonet and can be used for hexagonal screws or nuts of different diameters, the bayonet of this type of wrench is usually adjusted by thread rotation, and the stability is poor. When the screw is screwed, problems such as detachment or slippage often occur

Embodiment Construction

[0014] The multipurpose wrench of the present invention will be further described in detail through specific examples below.

[0015] like figure 1 , figure 2 As shown, the multi-purpose wrench includes a hollow circular shell 1, and the peripheral wall of the shell 1 is provided with eight sleeve holes 2 toward the center of the circle, and the eight sleeve holes 2 are hexagonal slot holes 21 or spline holes 22 of different sizes. , to be suitable for use with hexagonal screws or nuts of different sizes, eight sleeve holes 2 are evenly distributed along the circumferential direction of the housing, and the inner ends of the sleeve holes 2 communicate with each other. The casing 1 is provided with a booster rod hole 3 penetrating through the two side walls. The number of sleeve holes 2 can be changed arbitrarily according to actual needs, and all belong to the protection category of the present invention. The housing 1 can be integrally cast, and a layer of rubber can be c...

Description

technical field [0001] The invention relates to a wrench for screwing out hexagon screws or nuts. Background technique [0002] A wrench is one of the tools commonly used in people's work. The structure of the wrenches used to screw the hexagonal screws or nuts is too fixed today, and some wrenches can only correspond to one size of hexagonal screws or nuts. When encountering unsuitable hexagonal screws or nuts, the wrench must be replaced to continue working; Although some wrenches can adjust the width of the bayonet and can be used for hexagonal screws or nuts of different diameters, the bayonet of this type of wrench is usually adjusted by thread rotation, and the stability is poor. When tightening screws, problems such as detachment or slipping often occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-purpose wrench that can be used for hexagonal screws or nuts of different sizes without problems...
