[0035] The specific structure of the above-mentioned skeleton 35 is as follows:

[0036] Reference Figure 4 , Figure 5 , Figure 6 The skeleton 35 includes a connector 351a, a connector 351b, a plurality of connecting pieces 352, and a plurality of bone seats 353; the end faces of the connector 351a and the connector 351b are connected and installed with the adjacent support column 3111 by rotation; the plurality of connecting pieces 352 and the plurality of bone seats 353 are located between the two connectors 351a and the connector 351b, and are staggered; the two ends of the bone seat 353 are hinged with the adjacent connecting pieces 352, and the inner sides of the connectors 351a and the connector 351b are hinged with the adjacent connecting pieces 352; the pressure sensor 3533 is fixedly installed on the side of the bone seat 353 away from the frame 1; thus, each bone seat 353 has a certain degree of flexibility, and the connecting piece 352 between the two bone seats 353 limits the range of motion of the bone seat 353, so that the movement of the bone seat 353 is continuous, thereby realizing the arc adjustment or linear adjustment of the skeleton 35 in the later stage.

[0037] Among them: Reference Fig.10The connecting piece 352 includes a circular ring 3521, an inner ring seat 3522, and four cylinders 3523; the inner ring seat 3522 and the four cylinders 3523 are all located inside the circular ring 3521, the outer side of the inner ring seat 3522 is fixedly installed with the cylinders 3523, and the four cylinders 3523 are distributed in a cross shape; one end of the four cylinders 3523 away from the inner ring seat 3522 is fixedly connected to the circular ring 3521, and the inner ring seat 3522 and the circular ring 3521 are concentrically assembled;

[0038] Reference Figure 7 , Figure 8 , Fig. 9 A pair of hinged seats 3531 are provided on one side of the bone seat 353, and the pair of hinged seats 3531 are arranged vertically, and the inner sides of the pair of hinged seats 3531 are connected to the two opposite cylinders 3523 of the connecting piece 352 on the same side by rolling. A pair of hinged seats 3532 are provided on the other side of the bone seat 353 away from the hinged seat 3531, and the pair of hinged seats 3532 are arranged horizontally, and the inner sides of the pair of hinged seats 3532 are connected to the two opposite cylinders 3523 of the connecting piece 352 on the same side by rolling. In this way, the hinge between the connecting piece 352 and the bone seat 353 is realized, and the two bone seats 353 do not interfere with each other's movement.

[0039] In addition: the structure of the detection component 3 to achieve the shape adjustment of the skeleton 35 is as follows:

[0040] Reference Figure 2 A receiving column 3112 is installed on the inner side of the support seat 311 through a bearing, and the receiving column 3112 is arranged horizontally relative to the inner side of the support seat 311; the receiving column 3112 is located on the side of the support column 3111 close to the frame 1, and has no contact with the support column 3111; a control component 34 is fixedly installed on the outer side of the receiving column 3112, and a pull rod 341 is provided on the side of the control component 34 close to the support column 3111, and the end of the pull rod 341 away from the control component 34 is fixedly connected to the adjacent bone seat 353; thus, the two control components 34 provide a certain support force for the skeleton 35 through the connected bone seat 353, and the shape of the skeleton 35 is adjusted through the connected bone seat 353.

[0041] Reference Figure 2The detection component 3 also includes a control seat 32, the end face of the control seat 32 is slidably connected to the slide rail 21, and the outer side of the control seat 32 is slidably connected to the inner wall of the movable seat 2; the end of the control seat 32 away from the frame 1 is hinged with two support arms 321, and the ends of the two support arms 321 away from the control seat 32 are hinged to the adjacent connecting plate 31; thus, the control seat 32 moves on the slide rail 21, giving the two support arms 321 a push-pull force, and because the connecting plate 31 is limited by the guide rod 22, the two support arms 321 rotate around the control seat 32 to open, pushing the connecting plate 31 to move along the axis of the guide rod 22, and then being able to adjust the distance between the two support seats 311 to cope with the adjustment of the lateral distance of the skeleton 35.

[0042] Reference Figure 3 The end of the slide rail 21 away from the frame 1 is fixedly installed with an I-shaped frame 331, the I-shaped frame 331 is vertically crossed with the guide rod 22, and sliding keys are set at both ends of the I-shaped frame 331; two slide slot plates 332 are fixedly installed on the outer side of the receiving column 3112, and the slide slot plates 332 are respectively located on both sides of the control member 34; the slide slot of the slide slot plate 332 and the adjacent sliding key are a matching structure; thus, the support seat 311 drives the receiving column 3112 to move during the movement, and the receiving column 3112 pushes the slide slot plate 332 to move, and the matching sliding key limits its lateral movement, thereby making the slide slot plate 332 rotate with the receiving column 3112; then the receiving column 3112 drives the control member 34 to rotate, and the control member 34 controls the movement of the connecting bone seat 353 to realize the regulation of the skeleton 35.

[0043] Reference Figure 2 There are three control members 34 on each receiving column 3112, and three skeletons 35 on each supporting column 3111. The control members 34 and skeletons 35 at the same supporting seat 311 correspond one to one. Thus, multiple groups of data collection are realized through three groups of skeletons 35, which indirectly reduces the error range.

[0044] In summary, the measuring steps of the wall measuring tool are as follows: the staff first adjusts the shape of the skeleton 35 at the detection component 2 by moving the control seat 32, so that the arrangement of multiple pressure sensors 3533 is similar to the wall of the detection area; then the moving seat 2 is located at the bottom of the sliding end of the frame 1, and the frame 1 with the moving roller is moved to make the pressure sensor 3533 at the detection component 2 fit the wall of the detection area, and then the moving seat 2 is controlled by the screw mechanism to move upward from the bottom of the frame 1 to detect the regional wall. Therefore, the wall measuring tool ensures the accuracy of measurement while achieving rapid measurement, reduces measurement time and measurement error, and indirectly reduces time cost.

[0045] The control of the skeleton 35 of the above detection component 2 is as follows:

[0046] 1. When detecting the wall at the arc corner: the staff pulls the control seat 32 on the slide rail 21 to move toward the frame 1, and the control seat 32 gives a pulling force to the two support arms 321. Since the connecting plate 31 is limited by the guide rod 22, the two support arms 321 rotate and close around the control seat 32, pushing the connecting plate 31 to move inward along the axis of the guide rod 22; at the same time, the support seat 311 drives the receiving column 3112 to move during the movement, and the receiving column 3112 pushes the slide plate 332 to move, and the matching sliding key limits its lateral movement, thereby causing the slide plate 332 to rotate with the receiving column 3112; then the receiving column 3112 drives the control member 34 to rotate upward, and the control member 34 controls the movement of the connecting bone seat 353, and then the bone seat 353 pulls the adjacent bone seat 353 to move, forming an arc state.

[0047] 2. When detecting a normal straight wall: the staff pushes the control seat 32 to move away from the body 1, and the control seat 32 gives a thrust to the two arms 321. Since the connecting plate 31 is limited by the guide rod 22, the two arms 321 rotate and unfold around the control seat 32, pushing the connecting plate 31 to move outward along the axis of the guide rod 22; at the same time, the support seat 311 is driven to move, and the receiving column 3112 follows the movement, and the receiving column 3112 pulls the slide plate 332 to move, and the matching slide key limits its lateral movement, so that the slide plate 332 rotates with the receiving column 3112; then the receiving column 3112 drives the control member 34 to rotate downward, and the control member 34 controls the connection bone seat 353 to move, and then the bone seat 353 pushes the adjacent bone seat 353 to move, so that the bone seats 353 are arranged in a row to form a straight line state;

[0048] It should be noted that the parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art; the screw sliding mechanism in the present invention can be implemented by using the existing screw drive assembly.
