[0013] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the following disclosed base body implementation.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0015] The specific embodiments of the utility model will be further described below with reference to the drawings.

[0016] By Figures 1 to 5 It is given, including the upper and lower axial limit seat 1, the lower end of the limit seat 1 coaxially has clamping hole 2, the limit seat 1 is provided with a plurality of through holes 3 along the circumferential direction and upper and lower axial direction, the through hole 3 penetrates the limit seat 1, the clamping hole 2 is communicated with the clamping hole 2 and the clamping hole 2, and the clamping hole 2 is communicated with the clamping hole 2.

[0017] In order to facilitate use, the diameter of the clamping hole 2 is the same as the diameter of the FSD valve to be tightened.

[0018] In order to facilitate the removal of the tightening pin 4 from the through hole 3, the upper side of the tightening pin 4 is provided with a stop column 6.

[0019] In order to facilitate use, the tightening pin 4 needs at least two when used.

[0020] In order to avoid the fracture of the tightening pin 4 when used, the tightening pin 4 is made of 40Gr material.

[0021] In order to reduce the scratch on the FSD valve, the roughness of the inner surface of the clamping hole 2 is less than 0.8.

[0022] In order to make the tightening process more efficient, the lower end of the limit seat 1 is provided with a chamfer.

[0023] The utility model discloses when using, first, the FSD valve is placed on the recovery valve assembly upper end realizes the butt joint, then the limit seat 1 is placed on the FSD valve, and make FSD valve insert into the clamping hole 2, when rotating limit seat 1, limit seat 1 drive the through -hole 3 on it rotate, make the through -hole 3 of limit seat 1 with the valve hole on FSD valve one -to -one, then again screw the pin 4 is inserted into the through -hole 3 in proper order, and screw the pin 4 moves down in the through -hole 3 and makes the lower end insert into the valve hole of FSD valve, realizes the position fixation of limit seat 1 relative to FSD,

[0024] At this time, the movement of FSD valve X, Y, Z three directions and the rotation of X, Y axis are effectively limited, and the rotation of Z axis is positioned by screwing pin 4, with two sides a pin, six orientation degrees of freedom are limited, at this time, servo electric wrench can be used to insert into the tightening groove 5 and rotate limit seat 1, limit seat 1 is driven by screwing pin 4 to rotate FSD valve, so as to tighten and fix FSD valve and recovery valve.
