DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 A novel sliding locking fulcrum comprises a support 1 and a connecting member 5, wherein two symmetrically arranged spring sheets 2 are fixed on the support 1, an upper rotating column 4 and a lower rotating column 7 are rotatably sleeved on the support 1, one end of the upper rotating column 4, one end of the lower rotating column 7 and both ends of the connecting member 5 are provided with plug blocks 14 and slots 15 arranged in a circumferential array, the upper rotating column 4 and the lower rotating column 7 are respectively connected to the connecting member 5 through the plug blocks 14 and the slots 15, and two symmetrically arranged second card grooves 16 are provided on the side of the connecting member 5, and the spring sheet 2 abuts against the second card groove 16. By clamping the spring sheet 2 in the second card groove 16 on the connecting member 5, free rotation of the connecting member 5 can be avoided, and an eccentric pin 3 is fixed on the top of the upper rotating column 4.
[0022] Reference Figure 1 Four bolt holes 10 are provided on the support 1.
[0023] Reference Figure 2 The upper rotating column 4 is rotatably sleeved in the support 1 through the first bearing 12, and the lower rotating column 7 is rotatably sleeved in the support 1 through the second bearing 11.
[0024] Reference Figure 6 The handle 9 includes a sleeve 91, a slide rod 92, and an end cover 93. The sleeve 91 penetrates and is fixed in the lower rotating column 7. The slide rod 92 is slidably sleeved in the sleeve 91, and the end cover 93 is fixed to one end of the slide rod 92.
[0025] Reference Figure 1 , Figure 5 Two symmetrically arranged positioning pieces 6 are fixed on the lower rotating column 7, and a stopper 8 is fixed on the bottom of the support 1. The stopper 8 is provided with two symmetrically arranged first card grooves 13.
