While in the normal range, the trigger block H1 cannot trigger additional compensation actions. In the housing K, there are a chamber for installing the automatic compensation unit 300, specifically, an installation hole K2 for installing the actuating assembly 302, an installation cavity K3 for installing the adjusting assembly 303 and the hydraulic oil chamber 304, and the installation hole K2 and the installation cavity K3 are kept communicated, it should be noted that the installation hole K2 is arranged perpendicular to the slide 301 and kept communicated with the slide 301.
Furthermore, the actuating assembly 302 is installed in the slide 301, and the actuating assembly 302 includes an actuating rod 302a and a return spring 302b sleeved on the actuating rod 302 a; the top and bottom of the actuating lever 302a are provided with a slope X.

The adjusting part 303c comprises a fixed seat 303c-1, a clamping rod 303c-2 and a return spring 303c-3, wherein the fixed seat 303c-1 is fixed on the bottom side wall of the installation cavity K3, the clamping rod 303c-2 is arranged in the end side wall of the fixed seat 303c-1 through the return spring 303c-3, and one end, far away from the fixed seat 303c-1, of the clamping rod 303c-2 is provided with a limiting tooth P.
Further, the adjusting assembly 303 is used for adjusting the volume shape of the hydraulic oil chamber 304, wherein the driving rod 303a is driven by the trigger block H1 to move, and displacement is generated between the limiting rod 303b and the adjusting member 303c by pushing. Thereby changing the volume shape change of the hydraulic oil chamber 304.

It should be added that, in order to facilitate the monitoring system to actively regulate and control the volume shape of the hydraulic oil chamber 304, the oil chamber movable plate 304a may be directly controlled by a regulation and control motor S, and the regulation and control motor S may be directly connected to the driving rod 303a or the limiting rod 303 b.
The rest of the structure is the same as that of embodiment 1.
With reference to fig. 2 to 7, the compensation principle of the automatic compensation unit 300 is as follows: when there is no wear, the trigger blocks H1 on both sides of the piston rod H slide in the slide 301 to contact with the inclined plane X at the top of the actuating rod 302a, the actuating rod 302a is compressed to the bottom, and the inclined plane X at the bottom of the actuating rod 302a just contacts with the wedge surface Y at the end of the driving rod 303a, so that the driving rod 303a is not driven, i.e. the oil chamber movable plate 304a is not pushed.
When abrasion exists, the piston rod H deviates to the lower side of the piston rod through hole K1, when the trigger block H1 is in sliding contact with the inclined plane X at the top of the actuating rod 302a in the slide rail 301, the inclined plane X at the bottom of the actuating rod 302a can push the driving rod 303a to move towards the oil cavity movable plate 304a, meanwhile, the limiting rods 303B on the two sides of the driving rod 303a act, the process is that the clamping rod 303C-2 is squeezed and contracted by the tooth grooves C on the limiting rods 303B and enters the previous tooth groove C forwards, the clamping rod 303C-2 restores the original length under the action of the return spring 303C-3 and is clamped in the previous tooth groove C, the oil cavity movable plate 304a is integrally pushed by the two groups of limiting rods 303B, the shape of the hydraulic oil cavity 304 is changed, the supporting plate 304C is lifted, and the stuffing box B is supported. So that the piston rod H is returned to the original supporting height. At this time, when the trigger block H1 drives the actuating lever 302a, the inclined surface X at the bottom of the actuating lever 302a can only contact with the wedge surface Y at the end of the driving lever 303a, and cannot push the driving lever 303a to move. When it is required to be described, the length of the wedge surface Y in the horizontal direction is an adjustable section of wear.
