[0044] In the above arrangement, the driving assembly 20 is used to apply torque to the disassembly assembly 10, thereby ensuring that the disassembly assembly 10 can drive the union 100 to rotate in the first direction to achieve tightening with the liquid jacket pump head 200. And ensuring that the disassembly assembly 10 can drive the union 100 to rotate in the second direction to achieve loosening with the liquid jacket pump head 200. In this way, the disassembly and assembly of the union 100 is achieved.

At the same time, it also avoids the problem of damage to the union groove 101 caused by excessive force on a single union groove 101.

[0047] Specifically, Figure 2 and Figure 3 As shown, in one embodiment, the cylinder liner lock unloading plate 11 is provided with a plurality of groups of special-shaped grooves 111, and the plurality of groups of special-shaped grooves 111 are arranged at intervals along the circumference of the cylinder liner lock unloading plate 11, and the drive assembly 20 is engaged with the special-shaped grooves 111 to push the cylinder liner lock unloading plate 11 to rotate along the first direction or the second direction.

[0048] It should be noted that the drive assembly 20 in the present invention uses a linear method to push the cylinder lock unloading plate 11 to rotate, and its travel is limited. Therefore, the present invention is provided with multiple sets of special-shaped grooves 111, and the drive assembly 20 cooperates with the special-shaped grooves 111 at different positions to achieve tightening or loosening of the union 100.

[0049] Specifically, Figure 3 As shown, in one embodiment, the special-shaped groove 111 includes a locking groove 1111 and a shackle groove 1112, wherein the driving assembly 20 is engaged with the locking groove 1111 to push the cylinder liner locking plate 11 to rotate in a first direction, and the driving assembly 20 is engaged with the shackle groove 1112 to push the cylinder liner locking plate 11 to rotate in a second direction.

[0050] Specifically, Figure 3 As shown, in one embodiment, the shackle slot 1112 and the locking slot 1111 are symmetrically arranged relative to the radius of the cylinder liner locking and shackle disc 11.
