[0007] Preferably, a rear plate is installed on the U-shaped plate, and a telescopic bottom plate is installed on the rear plate.

[0008] Preferably, a rotating shaft is installed at the bottom of the U-shaped plate, and the two rotating shafts are installed to rotate together between the U-shaped plate and the bottom plate. The two rotating shafts are movably connected to the L-shaped protective plates, and circular holes are opened on the two L-shaped protective plates, and second handles are installed on the two L-shaped protective plates.

[0009] Preferably, a front baffle is installed on the U-shaped plate, and two sliding grooves are provided in the inner cavity of the bottom plate.

[0010] Preferably, the inner cavity of the bottom plate is provided with a mold container, a first handle is mounted on the mold container, and the mold container is slidably mounted in a slide groove.

[0011] Preferably, four supporting columns are installed on the bottom plate, and circular bases are installed on the four supporting columns.

[0012] Compared with the prior art, a copper sleeve press-fitting device using the above technical solution has the following beneficial effects:

[0013] 1. When the copper sleeve is installed on the workpiece of the utility model, the copper sleeve is placed on the moving plate and the three pressing heads move downward. When the pressing mechanism presses the copper sheet, batch pressing can be performed, which improves the work efficiency and solves the problem that only one can be pressed at a time during the pressing process;

[0014] Second, place the workpiece and the copper sleeve directly on the mold container, and then move the pressure head for pressing under the action of the cylinder. After the completion, use the handle to quickly take it out under the action of the slide, which is convenient for operation, saves time, improves work efficiency, and reduces the labor intensity of workers.
