The invention discloses a movable spanner, which comprises a handle part (20) and a spanner head part (30), wherein an annular engaging part (1) is formed on the spanner head part, the handle part is movably and detachably connected onto the annular engaging part in the circumferential direction of the annular engaging part, a plurality of pin holes (2) are arranged on the outer annular surface of the annular engaging surface at intervals in the circumferential direction, the handle part is provided with a hollow cavity, in addition, a movable connecting rod (3) is arranged in the hollow cavity, and the movable connecting rod extends out from the hollow cavity and is pressed into the pin hole. The movable spanner according to the invention can be flexibly operated in a narrow and small space, the jaw part of the movable spanner can be clamped on a screw nut according to the installation position of the screw nut, and then, the handle part is moved and connected onto a proper position on the annular engaging part of the spanner head part. After the spanner is operated to rotate for a certain angle, the handle part can move on the annular engaging part, the handle part and the annular engaging part can be connected after the handle part is regulated to the proper position, the subsequent operation is carried out, and the operation is convenient, flexible and efficient.
Description
technical field [0001] The invention relates to a wrench, in particular to an adjustable wrench for fastening nuts in a switch. Background technique [0002] Such as figure 1 and figure 2 As shown, in the installation structure of the turnout, since the actuating rod 50 is located between the sleeper rail 60 and the connecting rod 40, and the distance between the sleeper rail 60 and the connecting rod 40 is small, the screw or nut on the actuating rod 50 will 70, the working space is too small during the adjustment operation. When an ordinary wrench is used for operation, the wrench angle a of the wrench is generally not greater than 90 degrees. figure 2 The pulling angle a in is generally about 60°~80°. This is very unfavorable for maintenance personnel to perform wrench work, and it is difficult to adjust the wrench according to the installation position or angle of the hexagonal nut 70, and the wrench has too little rotation space, resulting in low working efficienc...
