One of the first connecting rods 6 is fixedly connected to the control rod 2, and the other first connecting rod 6 is fixedly connected to the cylinder body 1 through a fifth connecting rod. A rotating cylinder 303 is fixedly sleeved in the fixed frame 301. Two groups of rotating rings 304 are rotatably sleeved on the outer side of the rotating cylinder 303. During the connection process, the component connected to the viscous damper can be connected to the rotating ring 304 by threading to complete the connection operation of the viscous damper. This is a prior art and no unnecessary details are given.

The first gear 314 drives the threaded ring 313 to rotate, and the threaded ring 313 drives the second threaded rod 312 to rotate. Since the threaded ring 313 and the second threaded rod 312 are threadedly connected, and since the second threaded rod 312 and the rotating cylinder 303 are slidably connected up and down, and the threads on the outer sides of the second threaded rod 312 on the upper and lower sides are rotated in opposite directions, when the limiting cylinder 318 is rotated, the second threaded rod 312 will be driven to move in a direction close to each other, and the second threaded rod 312 drives the clamping plate 306 to move until the two clamping plates 306 are tightly against the rod, thereby completing the connection operation between the rod and the rotating cylinder 303.

At this time, with the limiting cylinder 318 as the center, the twist is rotated, and the twist drives the fourth gear 319 to rotate, and the fourth gear 319 can drive the fifth gear 321 to rotate. When the first gear 314 rotates, continue to press the fourth gear 319 until the baffle 340 can prevent the baffle rod 336 from rotating. At this time, the fourth gear 319 and the fifth gear 321 are disconnected. At this time, the knob is turned, the shaft drives the fourth gear 319 to rotate, and the fourth gear 319 drives the baffle rod 336 to rotate. The baffle rod 336 and the baffle 340 resist and drive the baffle 340 to rotate.

A control plate 311 is connected, a limiting cylinder 318 passes through the control plate 311, a protrusion 342 is fixedly connected to the inner wall of the control plate 311, a moving cavity 344 is opened in the limiting cylinder 318, two groups of moving plates 343 are slidably connected in the moving cavity 344, a fourth spring 345 is fixedly connected between the two groups of moving plates 343, the two groups of moving plates 343 pass through the moving cavity 344 and are slidably connected to the moving cavity 344, a moving ring 335 is fixedly sleeved on the outer side of the two groups of moving plates 343, and the outer sides of the moving ring 335 and the protrusion 342 are both smooth;

[0040] First, during the installation process of the first threaded rod 302 and the fixed frame 301, the fourth gear 319 is pressed, the fourth gear 319 drives the third connecting rod 339 to move, the third connecting rod 339 compresses the third spring 338, the third connecting rod 339 drives the fourth connecting rod 341 to move downward, the fourth connecting rod 341 and the moving plate 343 abut against each other and drive the moving plate 343 to move toward each other, the moving plate 343 compresses the fourth spring 345 and drives the moving ring 335 to move toward each other, the moving ring 335 and the protrusion 342 inside the control plate 311 abut against each other, due to the fastening plate 308 It is connected to the fixed frame 301 for left and right sliding, and the fastening plate 308 is fixedly connected to the control plate 311. Therefore, when the movable ring 335 and the protrusion 342 abut against each other, the protrusion 342 and the control plate 311 will be driven to move rightward as a whole. After the first threaded rod 302 is screwed into the thread groove 307, the fourth gear 319 is loosened. At this time, under the action of the first spring 310, the fastening plate 308 moves leftward as a whole, the fastening plate 308 and the first threaded rod 302 abut against each other, and the first spring 310 is in a stretched state, so that the connection between the first threaded rod 302 and the thread groove 307 is tighter, thereby improving the overall stability of the device.

[0042] During the installation of the viscous damper, the corresponding rod is inserted into the rotating cylinder 303, and the fourth gear 319 is pressed until the baffle 340 can prevent the baffle rod 336 from rotating. At this time, the fourth gear 319 and the fifth gear 321 are disconnected. At this time, the twist knob is turned, the rotating shaft drives the fourth gear 319 to rotate, the fourth gear 319 drives the baffle rod 336 to rotate, the baffle rod 336 and the baffle plate 340 abut against each other and drive the baffle plate 340 to rotate, the baffle plate 340 drives the limiting cylinder 318 to rotate, the limiting cylinder 318 drives the third gear 317 to rotate, and the third gear 317 drives the first gear 314 to rotate through the second gear 316 The first gear 314 drives the threaded ring 313 to rotate, and the threaded ring 313 drives the second threaded rod 312 to rotate.

[0043] During the connection process, the component connected to the viscous damper can be connected to the rotating ring 304 by threading to complete the connection operation of the viscous damper. This is a prior art and will not be described in detail.
