The outer sides of the two threaded rods 307 are threadedly connected with movable plates 308. The top and bottom of the two movable plates 308 are provided with limit assemblies 309 for placing them to rotate. A connecting rod 310 with one end passing through and extending to the opposite side of the two fixed boxes 306 is fixedly installed on the opposite side of the two movable plates 308.

A driving assembly 313 for driving the threaded rod 307 to rotate is provided on the top of the two fixed boxes 306.

[0026] It should be noted that, when connecting, first, the opposite sides of the two joints 301 are respectively threadedly connected to the left and right sides of the connecting rod 2, and the threads are fixed by set screws to loosen the threads. Then, the opposite sides of the two joints 301 are slidably connected to the inside of the two connecting grooves 302, and the two through holes 303 are made to correspond to the positions of the two fixing grooves 304, and then the two pins 305 are respectively slidably connected to the inside of the two through holes 303 and the two fixing grooves 304, so that the two joints 301 can be fixed by the two pins 305.

[0027] In this embodiment, the driving assembly 313 includes a rotating rod 3131 which is rotatably connected to the inside of the two fixed boxes 306 and one end of which passes through and extends into the inside thereof. The outer sides of the two rotating rods 3131 are provided with engaging assemblies 3132, and the tops of the two rotating rods 3131 are fixedly installed with knobs 3133.

[0028] The bottoms of the two rotating rods 3131 are rotatably connected to the inner bottom walls of the two fixed boxes 306 to ensure the stability of the rotation of the two rotating rods 3131. When the two knobs 3133 are rotated, the two knobs 3133 will drive the two rotating rods 3131 to rotate respectively.

[0029] In addition, the meshing assembly 3132 includes a worm fixedly mounted on the outside of the two rotating rods 3131, and a worm wheel meshing with the worm is fixedly mounted on the outside of the two threaded rods 307. When the two rotating rods 3131 rotate, the two rotating rods 3131 will respectively drive the two worms to rotate, and the two worms will respectively drive the two worm wheels meshing with them to rotate, and the two worm wheels will respectively drive the two threaded rods 307 to rotate.

The two baffles 311 can be used to limit the tops of the two pin shafts 305 to prevent the pin shafts 305 from falling off.

[0034] Example 3: Please refer to Figure 1 On the basis of the first and second embodiments, a transmission side cylinder block 4 is installed on the right side of the right operating side cylinder block 1 .

From the perspective of force conditions, the original screw connection screws are subjected to tensile force, and the force condition is not good. Now the operating side cylinder block 1 and the joint 301 are connected by a pin shaft 305.
