Detailed Description
The invention will be further described with reference to the drawings and specific examples.
Referring to fig. 1-2, a crank slider press-fitting adjusting mechanism comprises a frame, a handle seat 2, a transmission rod 5, an adjusting screw 4, a linear motion slide rail 6 and a slider; the handle seat 2 is rotationally fixed on the frame, an ear plate extends out of the side face of the handle seat 2, the transmission rod 5 is L-shaped, the short arm end of the transmission rod is rotationally connected with the ear plate, and the long arm end of the transmission rod is rotationally connected with the sliding block; the linear motion slide rail 6 is fixed on the frame, and the sliding block is limited in the linear motion slide rail 6 and can slide along the linear motion slide rail 6; the handle seat 2 is provided with a screw hole, the adjusting screw 4 is rotationally fixed in the screw hole, when the handle seat 2 is turned in place relative to the frame, the head of the adjusting screw 4 can prop against the short arm of the transmission rod 5, and the extension length of the adjusting screw 4 can be adjusted.
In this embodiment, referring to fig. 1-2, the handle base 2 is provided with a blind threaded hole for screwing with the externally threaded handle 1.
In this embodiment, referring to fig. 1-2, a portion of the handle seat 2 rotationally connected to the frame has a groove, an inner wall of the groove has a notch, a compression spring is disposed in the groove, one end of the compression spring is fixed to the inner wall of the groove, and the other end of the compression spring is connected to a small ball, and when the handle seat 2 is located at the initial position, the small ball is pressed into the notch by the spring to lock the initial position of the handle seat 2. It should be noted that the grooves shown in fig. 1-2 are planar views, and the depth of the grooves is not shown.
In this embodiment, the frame, the linear motion carriage 6, are all disposed upright, see fig. 1-2.
