Abstract

The invention discloses a lever arm mechanical device convenient for length adjustment. The device comprises a containing rod, a telescopic lever arm and a linkage shaft; an containing groove and a sliding groove are formed in the containing rod, and the sliding groove is located at the outer side of the containing groove; the telescopic lever arm is arranged above the containing rod, a mounting groove and an adjusting groove are formed in the telescopic lever arm, and a connecting ring is fixedly connected to the bottom of the telescopic lever arm; and the linkage shaft rotates at the bottomof the inner wall of the mounting groove. The invention relates to the technical field of lever arms. The lever arm mechanical device convenient for length adjustment adapts to the requirements of different users for the height; when the telescopic lever arm does not need to be used, a lifting rod can be completely stored in the containing rod, so that the space occupied when the telescopic leverarm is not used is saved; and a first connector and a second connector can be conveniently disassembled so that the height of the telescopic lever arm can be conveniently and manually adjusted, and the adaptability of length adjustment for the telescopic lever arm is improved.

Description

technical field [0001] The invention relates to the technical field of lever arms, in particular to a mechanical device for adjusting the length of a lever arm. Background technique [0002] The lever arm is used for the control lever of the loader, which is convenient for manual operation and control of the equipment, and improves the labor-saving degree of manipulation. The principle of the lever makes the operation more labor-saving and improves the convenience of operation. It cooperates with the mechanical transmission structure. It is convenient to control the equipment. [0003] In the prior art, when the existing lever arm is actually used, the length is a fixed structure. Since each user has different needs, the fixed-length lever arm cannot meet the needs of users of different heights and shapes. When the excessively long lever arm is not used, the length limitation will affect the normal operation and take up a lot of space. Contents of the invention [0004] ...
