It is worth noting that the pressure rod 4 is arranged between the aforementioned cylinder and the nozzle assembly through the pressure rod 4 positioning device, and the pressure rod 4 positioning device includes a hanging head 3 fixedly arranged at the end of the telescopic rod and a positioning ring 7 fixed on the nozzle assembly.

[0019] like Figure 2 As shown, the aforementioned hanging head 3 is a columnar structure, and a groove extending toward the center is opened from the side of the hanging head 3. A ball plunger 5 is fixedly provided at one end of the pressure rod 4. The pressure rod 4 is fixed by inserting one end of the pressure rod 4 with the ball plunger 5 into the hanging head 3 through the groove, and fixing the ball plunger 5 in the hanging head 3 through the set screw 6 that runs through the thickness direction of the hanging head 3. The other end of the pressure rod 4 needs to be embedded in the positioning ring 7, and the positioning ring 7 is used to limit the vertical movement direction of the pressure rod 4.

[0020] The structure of the nozzle assembly is described below. The nozzle assembly is fixed on one side of the lower end of the aforementioned Z-axis electric cylinder 1 with a base plate 2. The aforementioned nozzle assembly includes a nozzle 10, a rotary tube and a side top cylinder 9. A bearing is fixedly arranged on the aforementioned base plate 2, and bumps are arranged on the opposite sides of the outer edge of the rotary tube. The rotary tube is embedded in the bearing by the bumps to realize the movable fixation of the rotary tube in the nozzle assembly. The rotary tube can realize a certain angle of rotation by means of the position of its bumps. The first extreme movement position of the rotary tube is a vertical state, and the rotary tube is in a coaxial state with the positioning ring 7 fixed on the base plate 2 and the nozzle 10, so that the end of the pressure rod 4 can penetrate the height direction of the positioning ring 7 and press into the rotary tube.
