[0007] Furthermore, the hanging arm includes pull rods and screw rods, there are four pull rods and two screw rods, the lower ends of the pull rods are fixed to both sides of the support slot through a pin shaft, the upper ends of the two pull rods at the left end of the support slot are fixed with screw rods, and the upper ends of the two pull rods at the right end of the support slot are fixed with screw rods.

[0008] Furthermore, two mounting holes are respectively provided on the two side walls of the support slot, and the mounting holes are used to install the upper clamping device. The mounting holes are provided between the two pull rods of one side wall of the support slot.

[0009] Furthermore, the supporting slot is made of standard channel steel profile.

[0010] Furthermore, the push rod in the upper pressing device is a long threaded rod, which is convenient for adjustment.

[0011] The beneficial effects of the utility model are:

[0012] The support slot of the utility model is made of standard channel steel profile, which can accommodate leaf springs of different widths. The through hole at the bottom of the support slot is convenient for removing the positioning pin in the center of the leaf spring. The pull rod and screw of the hanging arm are fixedly connected to facilitate the hook operation. The pull rod can also swing left and right. When disassembling and assembling the leaf spring, the pull rod can be placed on both sides to facilitate the removal of the leaf spring. The top rod is a long threaded rod that can be rotated through the thread and then moved up and down on the pressure plate, which is convenient for disassembling and reassembling the leaf spring and tightening the leaf spring on both sides of the leaf spring. The utility model has a simple structure, is easy to manufacture, and is easy to use. It can maximize the versatility of the leaf spring subassembly and lifting, and is easy to carry and store. It can also meet the needs of front and rear leaf springs of different models, different widths, and different numbers of leaves. It has strong versatility and practicality.
