[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-4The utility model provides a technical solution: a hydraulic packing pliers for plastic strapping tape, comprising a pliers body 1, a battery 2 is fixedly installed on one side of the pliers body 1, a hydraulic cylinder 3 is fixedly installed near the middle position of the pliers body 1, and the output end of the hydraulic cylinder 3 is fixedly connected to a first bite block 4. A transmission groove 5 is provided on the side of the pliers body 1 away from the battery 2, and a bidirectional screw rod 6 is rotatably connected in the transmission groove 5. The bottom end of the bidirectional screw rod 6 is fixedly connected to a worm gear 7. The pliers body 1 is rotatably connected to the worm gear 7 on one side thereof. A symmetrically arranged extrusion block 9 is rotatably connected to the bidirectional screw rod 6, and the extrusion block 9 is slidably connected to the transmission groove 5. A limiting groove 10 is provided on one side of the pliers body 1 near the transmission groove 5, and a transmission block 11 is slidably connected in the limiting groove 10. A symmetrically arranged extrusion spring 12 is fixedly connected to one side of the transmission block 11, and one end of the extrusion spring 12 away from the transmission block 11 is fixedly connected to the limiting groove 10. A groove 13 is provided on one side of the transmission block 11, and a second bite block 14 is fixedly installed inside the groove 13.

[0018] One end of the worm 8 is fixedly connected to an adjusting button 15, and the surface of the adjusting button 15 is designed with an anti-slip structure, which makes it easy to rotate the worm 8 by means of the adjusting button 15. The worm 8 and the worm wheel 7 are arranged correspondingly, and the worm 8 is meshed with the worm wheel 7, which makes it easy for the worm 8 to transmit the worm wheel 7. The two extrusion blocks 9 are designed with a wedge-shaped structure, and the inclined side of the two extrusion blocks 9 fits with the transmission block 11, which makes it easy for the two extrusion blocks 9 to extrude and transmit the transmission block 11. The transmission block 11 is designed with a rectangular structure, and the side of the transmission block 11 close to the extrusion block 9 is designed with an inclined structure, which is convenient for extrusion transmission.

[0019] When the worm gear 8 is rotated in the opposite direction, the worm gear 8 drives the worm wheel 7 to rotate, and the worm wheel 7 drives the bidirectional screw rod 6 to rotate, and the bidirectional screw rod 6 drives the two extrusion blocks 9 to move toward each other. The extrusion blocks 9 moving toward each other squeeze the transmission block 11, and the transmission block 11 squeezes the extrusion spring 12. The squeezed transmission block 11 drives the second bite block 14 to move along the limit groove 10 toward the first bite block 4. At this time, the distance between the first bite block 4 and the second bite block 14 becomes shorter, which is suitable for strapping with smaller thickness. The worm gear 8 is rotated in the opposite direction, and the worm gear 8 drives the bidirectional screw rod 6 to rotate through the worm wheel 7, and the bidirectional screw rod 6 drives the two extrusion blocks 9 to reset. At this time, the transmission block 11 loses the extrusion of the extrusion block 9, and the transmission block 11 that loses the extrusion of the extrusion block 9 is reset under the action of the extrusion spring 12. At this time, the distance between the first bite block 4 and the second bite block 14 becomes longer, which is suitable for strapping with larger thickness.
