Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "upper, lower" and "top, bottom" etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, and in the case of not making a contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be interpreted as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

As shown in fig. 1-13, a scissor fork type fixing mechanism comprises a cylinder 3, a frame 4, a scissor fork assembly 5 and a supporting block 6, wherein two ends of the frame are respectively fixedly connected with a cylinder body and a supporting block of the cylinder, a piston rod of the cylinder is positioned in the frame and fixedly provided with a support 7, a rotating shaft 8 is fixedly provided on the support, the scissor fork assembly comprises a first scissor arm 11 and a second scissor arm 12, the lower ends of the first scissor arm and the second scissor arm are rotatably matched with the rotating shaft, a limiting shaft 13 is fixedly provided on the frame, a limiting groove 14 is provided on each of the first scissor arm and the second scissor arm, the upper end of the limiting groove is vertically arranged, the lower end of the limiting groove is inclined towards the lower oblique direction, the lower end of the limiting groove on each of the first scissor arm and the second scissor arm is inclined towards the opposite direction, and the limiting shaft is in sliding fit with the limiting groove, run through on the tray and be provided with the hole of stepping down that allows first scissors arm and second scissors arm to pass, the upper end fixed mounting of first scissors arm and second scissors arm has briquetting 15, two reference columns 16 have on the tray, the reference column is located the both sides in the hole of stepping down, the upper end of reference column has location end 17.

Thus, as shown in fig. 1, the reinforcing member 1 is provided with holes 2, and the scissors-type fixing mechanism is used for fixing the reinforcing member. When fixing the reinforcement, the piston rod of cylinder upwards stretches out, drive scissors fork subassembly motion, under the effect of spacing axle, scissors fork upward movement, because the lower extreme slope of spacing groove sets up, scissors fork upward movement changes upwards inward movement into, make the distance of first scissors arm and second scissors arm upper end reduce, after passing first scissors arm and second scissors arm with the hole site of reinforcement, the piston rod of cylinder contracts downwards, drive scissors fork subassembly downward movement, under the effect of spacing groove, the upper end outward movement of first scissors arm and second scissors arm, utilize the briquetting to compress tightly the reinforcement on the tray.
