Embodiment Construction

[0014] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 The steering extension wrench with a bracket includes a gripper shell, a wrench inner long shaft 1, a wrench inner short shaft 2, a first bevel gear 3, a second bevel gear 4 and a bolt sleeve 5, the gripper shell Comprising a long shell 6 and a short shell 7, the long shell 6 has a first long hole 8 along its length direction, the short shell 7 has a second long hole 9 along its length direction, the long shell 6 One end of one end is connected with one end of the short shell 7. The preferred long shell 6 and short shell 7 of the present application are made by welding. The long shell 6 and the short shell 7 described in the present application are perpendicular to each other. The first long hole 8 communicates with the second elongated hole 9, the inner major axis 1 of the wrench is rotated and set in the first elon...

Abstract

The invention discloses a steering extended wrench with a support. The steering extended wrench comprises a gripper shell, a wrench inner long shaft, a wrench inner short shaft, a first bevel gear, asecond bevel gear, a bolt sleeve and the shell fixing support; the gripper shell comprises a long shell and a short shell, a first slot hole is formed in the long shell, a second slot hole is formed in the short shell and is communicated with the first slot hole, the wrench inner long shaft is rotationally arranged in the first slot hole, the first bevel gear is arranged at one end of the wrench inner long shaft, the wrench inner short shaft is rotationally arranged in the second slot hole, and the second bevel gear is arranged at one end of the wrench inner short shaft and is meshed with thefirst bevel gear; the bolt sleeve is detachably installed at the end, away from the long shell, of the wrench inner short shaft, and a connecting piece for applying torque to the wrench inner long shaft is arranged at the end, away from the shell, of the wrench inner long shaft. The steering extended wrench with the support has the advantages that the wrench can be operated to fasten a bolt without moving the gripper shell, so that time and energy are saved, and bolt fastening quality is ensured.

Description

technical field [0001] The invention relates to a steering extension wrench with a bracket. Background technique [0002] The rotor of the generator is inside the machine pit, and the position of the bolts on the rotor is hidden. It is difficult to remove it without lifting the rotor. It can only be disassembled by a welded extension wrench deep into the interior. Due to the limited operating space, only With a little rotation, due to the long length of the extension rod, the bolt can easily come out of the wrench, and repeated operations can easily lead to damage to the bolt, making it more difficult to reinstall the bolt and unable to control the torque. It is necessary to design a wrench that can perform bolt fastening without moving the operating rod, so as to save time and energy and ensure the quality of bolt fastening. Contents of the invention [0003] The invention relates to a steering extension wrench with a bracket, which solves the technical defect in the pri...
