detailed description

As shown in Figures 1 to 7, the utility model mainly includes a first fixing assembly and a second fixing assembly, and the utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the first fixing assembly includes a first base 1, a support 11, a support block 12, a pressure plate 13 and a handle 15, the first base 1 is an inverted U-shaped metal piece, and the first base 1 Ear plates are provided on both sides of the ear plate, and first mounting holes 10 are provided on the ear plates. A pair of bearings 11 are arranged on the top of the first base, and a support block 12 is rotatably installed in one of the supports. As shown in Figure 7, a groove 6 is provided on the top of the support block, and a A rotating shaft 61 is fixed on the side, and two first fixing holes 62 whose axes are perpendicular to each other are arranged on the rotating shaft. A second fixing hole 64 is provided on the supporting block, and the second fixing hole is located in the groove. A notch, 63, is also provided on the supporting block, so that the pressing plate 13 is installed conveniently. As shown in Fig. 2 to Fig. 4, a pressing plate 13 is hinged 2 in the gap of each supporting block, and the pressing plate is a square metal plate, and a second bolt 16 is threaded on the pressing plate. When installing, place the two ends of the bone plate 5 in the grooves on the two supporting blocks respectively, and then realize the locking of the bone plate through the second bolt, and the second bolt passes through the bone plate and extends into the second fixing hole . A handle 15 is fixed on the rotating shaft of one of the support blocks, and the rotation of the support block can be realized by driving the handle.
