The polyurethane roller is connected to the slot of the ratchet roller through the blocking protrusion, so that the polyurethane roller rotates synchronously with the ratchet roller.

[0011] The advantages and positive effects of the utility model are:

[0012] 1. The pressure handle of the utility model is a spring telescopic structure. Only when the pressure of pushing the pressure handle is greater than 2 kg / cm2, the pressure adjustment mechanism can unlock the ratchet roller, thereby rotating the polyurethane roller on the ratchet roller to press the double-sided tape.
