The side of the bottom mold 201 is provided with an exhaust hole 204 connected to the external air pipe 207, and the bottom mold 201 is provided with an air channel 205 connected to the adsorption hole 203. The other end of the air channel 205 is connected to the exhaust hole 204. The air pump 206 continuously extracts air from the exhaust hole 204 of the bottom mold 201, and the adsorption holes 203 on the adsorption area 202 will continuously inhale air and discharge it to the exhaust hole 204 through the air channel 205, so that the copper busbar heat shrink tube is adsorbed on the upper end surface of the bottom mold 201; the air pump 206 is fixed on the hand pressure punch 101, and the air pump 206 can be fixed to the side of the hand pressure punch 101 or the edge of the bottom plate 102 of the hand pressure punch 101 by nuts and the like. The air pump 206 is connected to the bottom mold 201 through an air pipe 207, and the two ends of the air pipe 207 are respectively connected to the air extraction hole 204 and the air pump 206. If the air pump 206 is not needed to extract air for fixing, the copper bar heat shrink tube is placed on the bottom mold 201, so that the cutting part of the copper bar heat shrink tube is located at the edge of the bottom mold 201, and then it can be cut by the hand press 101; if the air pump 206 is needed to extract air for fixing, the copper bar heat shrink tube is placed on the bottom mold 201, so that the cutting part of the copper bar heat shrink tube is located at the edge of the bottom mold 201, and then the power is turned on and the switch 208 is turned on.
