Abstract
The invention discloses a wrench with a length-adjustable handle. The wrench comprises a head and a handle. The head comprises a head body, and one end of the head body is provided with an opening used for clamping a nut. The handle can be disposed at the other end of the head body and comprises at least one extension tube. The extension tubes can be mutually fitted to elongate the handle. The connection between the extension tubes and the head and the mutual connection of the adjacent extension tubes allow the length of the handle to be changed, thus the demands of work environment are met. The wrench is simple in structure; the length of the handle of the wrench can be adjusted by means of adding or decreasing the extension tubes according to application needs.
Description
Technical field
The present invention relates to a kind of improvement of spanner, refer in particular to a kind of can be according to using needs, by the mode that increases or reduce extension tube, regulate the spanner of adjustable handle length of length of the handle of spanner.
Background technology
Traditional spanner, comprise Wrench head, handle; One end of described Wrench head is provided with peristome; Described peristome is used for binding nut; Described handle is arranged on the other end of Wrench head; The length of normal conditions lower handle is fixed, but in actual production process, in process as the maintenance to machine, when especially narrow for the maintenance location comparison, need spanner shorter, in order to can use spanner, and larger to some screws permanent in bad repair or the common moment that needs of nut, at this moment, need again the decreased food of spanner long, and traditional spanner is fixed due to handle director degree, so that can't meet above-mentioned needs; For this reason, needing that exploitation is a kind of can be according to using needs, by the mode that increases or reduce extension tube, regulates the spanner of adjustable handle length of length of the handle of spanner.
