After the motor is started, the threaded rod 8 rotates and drives the slider 5 to move up and down along the first groove 4 through the principle of threaded transmission. The hydraulic head 14 is installed at the first groove 4 and is clamped and fixed by the L-shaped plate 10. When the hydraulic head 14 needs to be replaced, the slider 5 is first moved up or down to an appropriate position by controlling the motor. The L-shaped plate 10 moves in the clearance groove 9 on the slider 5 by means of hinged or sliding connection, and assists in completing the fixing or releasing operation of the hydraulic head 14, and realizes rapid locking or unlocking. The guide rod 12 in the first groove 4 provides precise guidance for the slider 5 to ensure that its motion trajectory is stable and without deviation. The heat dissipation holes 13 on the piston rod 2 effectively improve the heat dissipation performance of the motor during long-term operation, and prevent performance degradation or damage caused by overheating. At the same time, the protective pad 11 added at one end of the L-shaped plate 10 strengthens the connection with the end of the hydraulic head 14, and avoids scratching the outer wall of the hydraulic head 14.

[0022] like Figure 2 As shown, one end of the L-shaped plate 10 is clamped and arranged inside the clearance groove 9.

[0023] In this embodiment, one end of the L-shaped plate 10 is designed to be snap-fitted into the clearance groove 9, thereby ensuring a stable connection and facilitating operation.

[0024] like Figure 2 As shown, one end of the L-shaped plate 10 is slidably connected to a hinge rod, and one end of the hinge rod is hingedly arranged inside the clearance groove 9.

[0033] In this embodiment, a protective pad 11 is also installed at one end of the L-shaped plate 10 to protect the machine from accidental damage during operation and also improve the safety of the operation.

[0034] Working principle: The motor is located in the second groove 7, and its output shaft is directly connected to one end of the threaded rod 8. After the motor is started, the threaded rod 8 rotates and drives the slider 5 to move up and down along the first groove 4 through the principle of threaded transmission. The hydraulic head 14 is installed in the first groove 4 and is clamped and fixed by the L-shaped plate 10. When the hydraulic head 14 needs to be replaced, the slider 5 is first moved up or down to the appropriate position by controlling the motor. The L-shaped plate 10 moves in the clearance groove 9 on the slider 5 by means of hinged or sliding connection, assisting in the fixing or releasing operation of the hydraulic head 14, and realizing quick locking or unlocking. The guide rod 12 in the first groove 4 provides precise guidance for the slider 5 to ensure that its motion trajectory is stable and without deviation. The heat dissipation holes 13 on the piston rod 2 effectively improve the heat dissipation performance of the motor during long-term operation, preventing performance degradation or damage due to overheating. At the same time, the protective pad 11 added at one end of the L-shaped plate 10 strengthens the connection with the end of the hydraulic head 14, while avoiding scratching the outer wall of the hydraulic head 14.
