Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

It is noted that, unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In the present invention, unless stated to the contrary, the use of the terms "upper and lower" are generally used with respect to the orientation shown in the drawings, or with respect to the vertical, vertical or gravitational direction; likewise, for ease of understanding and description, "left and right" are generally to the left and right as shown in the drawings; "inner and outer" refer to the inner and outer relative to the profile of the respective member itself, but the above directional terms are not intended to limit the present invention.

According to the figures 1 to 3, the plate spring 2 cradle front and back pressure combining piece comprises a support 1, a plate spring 2 and a leather roller holding seat 3, wherein the front end of the plate spring 2 is riveted with the leather roller holding seat 3, the tail end of the plate spring is bent into a U shape and arranged in the support 1, an adjustable pressure screw 7 (shown in figure 3) is connected to the support 1 in a threaded mode, and the free end of the pressure screw 7 abuts against the tail end of the plate spring 2.

According to the figure 2, the other end of the pressure spring opposite to the plate spring 2 is connected with an anti-skid block 5 (as shown in figure 4), and the end face of the fixed block 4 attached to the anti-skid block 5 is provided with anti-skid grains.
