DETAILED DESCRIPTION
[0014] The present invention will be further described below with reference to the accompanying drawings.

A limit screw 133 is provided for rotating the internal thread of the threaded connection groove 132. The pressure sensor 14 is fixedly arranged between the groove 131 and the placement plate 122; the electric push rod 15 is inclined as a whole, and its upper end is hinged to the hinge seat 18, and the lower end is hinged to the upper part of the inclined edge of the middle connecting plate 13; the clamping block 16 is located above the clamping groove a171 and is fixedly connected to the support rod 17 by a limit bolt, and a semicircular clamping groove b161 is provided at the middle of the lower surface of the clamping block 16 at a position corresponding to the clamping groove a171. The structure of the clamping groove b161 is the same as that of the clamping groove a171, and they cooperate with each other to form a circular limit gap, and a connecting shaft 19 is provided for longitudinal rotation inside the limit gap; the tensioning roller 2 is longitudinally arranged between the connecting shafts 19 in the two brackets 1 and is fixedly connected concentrically with the connecting shaft 19.
[0016] The external thread of the limit screw 133 is rotatably sleeved with the limit nut 134; the support rod 17 is L-shaped as a whole, and the support rod 17 and the hinge seat 18 are integrally connected; positioning grooves 172 are provided on both sides of the right end face of the support rod 17, and positioning blocks 162 are provided on both sides of the lower surface of the clamping block 16 to match the positioning groove 172 structure. The setting of the positioning blocks 162 and the positioning grooves 172 can improve the accuracy and convenience of the operation when the clamping block 16 is installed above the support rod 17; a placement groove 123 is provided in the middle position of the upper surface of the placement plate 122, and the lower end of the pressure sensor 14 is located in the placement groove 123 and is fixedly connected to the bottom surface of the placement groove 123, and the upper end is fixedly set in the groove 131. The setting of the placement groove 123 and the groove 131 can facilitate the fixed clamping of the pressure sensor.
[0017] During installation, the present invention utilizes the support rod 17 and the clamping block 16 to realize the limiting connection through the limiting bolt, and the limiting gap formed by the cooperation between the clamping slot a171 and the clamping slot b161 and the rotational sleeve connection of the connecting shaft 19 can complete the rotational installation of the tensioning roller 2 between the two brackets 1.
[0018] When the present invention is in use, the process of measuring the tensioning force of the mesh is as follows: first, the reaction force of the mesh on the tensioning roller 2 during the tensioning of the mesh is utilized to cause the support rod 17 to deflect clockwise around the connection point between the support rod 17 and the first support 11. Thus, during the clockwise deflection of the support rod 17, the downward pressure generated by the hinge seat 18 on the electric push rod 15 is utilized, and in conjunction with the hinge connection of the two ends of the inclined edge of the intermediate connecting plate 13 with the electric push rod 15 and the second support 121, the intermediate connecting plate 13 as a whole deflects clockwise around the upper end of the second support 121. At this point, during the deflection of the intermediate connecting plate 13 by the downward pressure, the downward pressure generated during the clockwise deflection of the intermediate connecting plate 13 can be detected by the pressure sensor 14. Finally, the tensioning force of the mesh is determined by this pressure. That is, the greater the pressure on the pressure sensor 14, the tighter the mesh and the greater the tension; the smaller the pressure on the pressure sensor 14, the looser the mesh and the smaller the tension. The operation of adjusting the tension of the mesh carpet is as follows: when the tension of the mesh carpet is large, it can be retracted by controlling the electric push rod 15. At this time, the two ends of the electric push rod 15 are respectively hinged with the hinge seat 18 and the middle connecting plate 13. When the electric push rod 15 is retracted, the hinge seat 18, the support rod 17 and the tensioning roller 2 can be driven to move clockwise with the upper end of the first support 11 as the center. As the tensioning roller 2 deviates clockwise, the tension of the mesh carpet and the reaction force on the tensioning roller 2 are reduced. On the contrary, when the tension of the mesh carpet is small, it can be expanded by controlling the electric push rod 15. At this time, the two ends of the electric push rod 15 are respectively hinged with the hinge seat 18 and the middle connecting plate 13. When the electric push rod 15 is expanded, the hinge seat 18, the support rod 17 and the tensioning roller 2 can be driven to move clockwise with the upper end of the first support 11 as the center. The center moves counterclockwise, and as the tensioning roller 2 deviates counterclockwise, the tension of the mesh and the reaction force on the tensioning roller 2 increase, thereby adjusting the tension of the mesh. The present invention adopts this structure to improve the convenience and accuracy of the mesh tension adjustment operation. Moreover, the present invention utilizes the arrangement of the placement plate 122, the placement groove 123 and the groove 131, and can achieve the fixed clamping of the pressure sensor 14 through the cooperation of the placement groove 123 and the groove 131. The arrangement of the threaded connection groove 132 and the limit screw 133 can be used to play a protective role through the limit screw 133, so as to avoid the pressure sensor 14 being squeezed and damaged due to excessive pressure applied by the intermediate connecting plate 13 to the pressure sensor 14. In general, the present invention has the advantages of convenient operation and use and high adjustment accuracy.
