Abstract
The invention discloses a ratchet wrench. The ratchet wrench comprises a handle (1) and a ratchet mechanism, wherein the ratchet mechanism comprises a tooth ratchet (5). An installation hole (6) which is used for installing a cutter bar is formed in an assembling part (5.1) arranged at the front end of the tooth ratchet (5). Magnetic steel (7) is arranged at the inner bottom of the installation hole (6). The assembling part (5.1) is sleeved with an assembling piece (8). The assembling piece (8) is connected with the magnetic steel (7) through a plug pin (9). Two long holes (5.1.1) which are used for the plug pin (9) moving along the tooth ratchet (5) axis direction are symmetrically formed in a periphery wall of the installation hole (6). The ratchet wrench further comprises components which are used for locating the assembling piece (8) or driving the assembling piece (8) to move along the axial direction. The ratchet wrench has the advantages that the components are pushed to drive the assembling piece to move along the axial direction to enable the plug pin and the magnetic steel to move synchronously. When the assembling piece and the magnetic steel move to the limiting position, the assembling piece and the front end surface of the magnetic steel form a groove which is bigger than the installation hole, a cutter handle and the cutter bar which is matched with the groove can be installed at the moment, and the cutter is enabled to still have adsorption capacity.
Description
Technical field
The present invention relates to a kind of for instrument that is fastening or dismounting, particularly relate to a kind of ratchet spanner.
