Abstract

A slab spanner comprises a spanner head and a handle, wherein a combination opening is formed in one side of the spanner head and penetrates through the top surface and bottom surface of the spanner head. The handle comprises a first handle section and a second handle section. The second handle section comprises an open end and a holding end opposite to the open end, and the open end of the second handle section is provided with a sliding space extending towards the holding end. A connected end of the first handle section is connected with the spanner, and an inserted end of the first handle section is inserted into the sliding space of the second handle section in a sliding mode. The spanner further comprises a clamping structure which comprises a combination sleeve, a sleeve barrel and a plurality of clamping pieces extending out of one end of the sleeve barrel at intervals. The sleeve barrel is arranged on the second connecting section in a sleeving mode and fixed to the second connecting section. The multiple clamping pieces surround the first connecting section and abut against the first connecting section. The combination sleeve is arranged on the first connecting section in a sleeving mode, and can move to be arranged on the multiple clamping pieces in a sleeving mode to press the multiple clamping pieces to clamp the first connecting section. The length of the handle of the slab spanner can be changed, and thus the universality of the slab spanner is reinforced.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a flat wrench. Background technique [0002] Flat wrench is a kind of tool commonly used in life, is used for screwing fastener such as nut, screw etc., usually comprises wrench and the handle that is connected with wrench. [0003] When the operator uses a flat wrench to screw the fastener to tighten or loosen the fastener, since different fasteners require different forces, the operator needs to choose a flat wrench with an appropriate handle length to screw the fastener to achieve labor-saving and The purpose of convenient operation. [0004] However, the length of the handle cannot be changed in the traditional flat wrench, and the operator needs to prepare a plurality of flat wrenches with different handle lengths for the operator to choose from, which leads to the poor versatility of the traditional flat wrench. Contents of the invention [0005] In view of this,...
