Therefore, the invention arranges the first electric telescopic rod on the second electric telescopic rodThe three telescopic rods are provided with the pins and the support columns, so that after the plug-in units are inserted into the corresponding pins, the corresponding support columns act on the first transverse plate to enable the first transverse plate to incline, and the size of each support column can be set to be any size, so that the first transverse plate can be accurately inclined, the corresponding support rods can be accurately and vertically arranged, and the difference values of the corresponding X values when the adjacent support rods are vertically arranged are equal and can be easily realized. In addition, the invention designs the plug pin and the support post on the third telescopic rod so as to ensure that the plug-in unit is positioned under one plug pin every time the second electric telescopic rod extends for a corresponding length, after the plug-in unit is inserted into the plug pin, the corresponding support post is abutted against the first transverse plate to enable the first transverse plate to incline, the corresponding support rod is vertically arranged, and the inclination of the first transverse plate is changed and the vertically arranged support rod is also changed along with the extension of the second electric telescopic rod.

Step S102, aiming at the ith support from right to left, wherein i is an integer larger than 1 and smaller than N, straight lines of the first transverse plate when the first transverse plate moves forwards for the (i-1) th time, moves forwards for the (i) th time and moves forwards for the (i + 1) th time respectively and forms corresponding angles with the horizontal line are drawn, and the intersection point of the straight lines drawn correspondingly when the (i-1) th time moves forwards and moves forwards for the (i + 1) th time is taken as a first intersection point (x)i1，yi1) And the intersection of the drawn straight lines corresponding to the i-th advance and the i + 1-th advance is taken as a second intersection (x)i2，yi2) The coordinates of the free end of the ith strut from right to left are (x)i0，yi0) Wherein x isi0Less than xi1And is greater than xi2，yi0Less than yi1And is greater than yi2I.e. the free end of the i-th strut from right to left and theAnd a connecting line between the first intersection point and the second intersection point is abutted. For example, referring to fig. 3, the left marked lines in the figure respectively show the lines drawn when the first horizontal plate moves forward from 1 st to 5 th times and the first horizontal plate respectively forms corresponding angles with the horizontal line, and for the 4 th pillar from right to left, the intersection point of the lines drawn correspondingly from the 3 rd forward movement to the 4 th forward movement is taken as the first intersection point (x)41，y41) The intersection of the lines (r) and (v) drawn corresponding to the 4 th forward movement and the 5 th forward movement is defined as a second intersection (x)42，y42) It can be seen that in order to ensure that the 4 th forward movement of the first cross plate only abuts the 4 th post from right to left, the coordinates (x) of the free end of the 4 th post40，y40) In, x40Should be less than x41And is greater than x42，y40Should be less than y41And is greater than y42. Further, as can be seen from fig. 3, when the straight line r abuts on the 4 th strut from right to left, the X values corresponding to the free ends of the 3 rd strut and the 5 th strut from right to left are all smaller than X40Therefore, the first transverse plate can be abutted with only one of the support columns after moving forward for a corresponding distance.
Step S103, for the 1 st strut from right to left, determining the coordinate (x) of the free end of the 2 nd strut from right to left20，y20) Coordinate (x) of the corresponding first intersection point21，y21) Determining the coordinates (x) of the free end of the 1 st strut from right to left10，y10) Wherein x is10Greater than x21，y10Greater than y21。
Step S104, aiming at the Nth strut from right to left, determining the coordinate (x) of the free end of the Nth-1 strut from right to left(N+1)0，y(N+1)0) Coordinate (x) of the corresponding second intersection point(N+1)2，y(N+1)2) Determining the coordinates (x) of the free end of the Nth strut from right to leftN0，yN0) Wherein x isN0Less than x(N+1)2，yN0Less than y(N+1)2。
Therefore, the invention designs the vertical length and the arrangement position of each support on the third telescopic rod, and the contact priority sequence between the first transverse plate and each support column in the process that the first transverse plate horizontally moves forwards towards each support column direction is designed (namely, each support column is sequentially contacted with the first transverse plate according to the sequence from right to left), can ensure that only one support post is abutted with the first transverse plate when the first transverse plate moves forwards once in the stepping process, after the first cross plate and the horizontal line are sequentially abutted with each support from right to left, the included angle between the first cross plate and the horizontal line is gradually increased, so that the invention can be seen in that by means of each support on the third telescopic rod, can avoid adopting electronic telescopic link to adjust the contained angle between this first diaphragm and the water flat line at first diaphragm antedisplacement in-process to can guarantee the regulation precision of first diaphragm gradient.

step S102, judging whether the received length to be stretched is equal to integral multiple of the first length, if so, executing step S103, otherwise, executing step S104;
step S103, controlling the second electric telescopic rod 3 to extend by a corresponding length until the plug-in unit 4 is positioned under the Nth plug pin 10 from left to right, controlling the first electric telescopic rod 2 to contract so as to insert the plug-in unit 4 into the Nth plug pin 10, wherein the Nth pillar 11 from right to left is abutted against the first transverse plate 5, so that the Nth supporting rod 7 is vertically arranged, controlling the second electric telescopic rod 3 to drive the third telescopic rod 9 to stretch, and keeping the Nth supporting rod 7 vertically arranged so as to enable the distance between the X value corresponding to the Nth supporting rod 7 and the stretching starting point of the electric stretching device to be equal to the length to be stretched;
step S104, obtaining a remainder of the length to be stretched and the first length, dividing the remainder by delta X to obtain j, taking the Nth-j plug pins from left to right as plug pins to be inserted, wherein j is an integer greater than 0 and less than N, and executing step S105;
step S105, controlling the second electric telescopic rod 3 to extend by a corresponding length until the plug-in unit 4 is positioned under the Nth-j plug pin 10 from left to right, controlling the first electric telescopic rod 2 to contract so as to insert the plug-in unit 4 into the Nth-j plug pin 10, wherein the Nth-j support post 11 from right to left is abutted against the first transverse plate 5, so that the Nth-j support rod 7 is vertically arranged, controlling the second electric telescopic rod to drive the third telescopic rod 9 to extend and contract, and keeping the Nth-j support rod 7 vertically arranged so that the distance between the X value corresponding to the Nth-j support rod 7 and the extension starting point of the electric extension and contraction device is equal to the length to be extended and contracted.
