[0007] The other end of the rocker arm is rotatably connected to the nut, and the side end of the nut is rotatably connected to the other end of the rocker arm through an axle pin. A groove is provided on the clamping plate. When the rocker arm is embedded in the clamping plate, the axle pin on the nut is embedded in the groove.
[0008] When the nuts connected at both ends of the same rocker arm are higher than the axle pin, the nuts are forward threaded nuts.
[0009] When the nuts connected at both ends of the same rocker arm are lower than the axle pin, the nuts are reverse threaded nuts, and the positive and reverse directions of the nuts ensure the synchronization of the rocker arm movement when the stud rotates, that is, when the stud rotates, all the rocker arms are retracted or extended.
[0010] The stud is rotationally connected to the base, including being rotationally connected via a bearing.
[0011] The number of the clamp components is multiple, and the multiple clamp components are distributed in a ring array along the outer extension of the plate.

[0021] The utility model is described in detail below in conjunction with the accompanying drawings.
[0022] A movable pressure plate includes a base 1, on which a clamp assembly 2 is provided, and the clamp assembly 2 is used to fix a plate 3. The clamp assembly 2 includes a stud 4, on which a nut 8 is sleeved, and a rocker arm 6 is provided between the nut 8 and a clamp plate 5. The operating mechanism is to rotate the stud 4 to move the nut 8 up and down, and finally realize the horizontal movement of the clamp plate 5 through the transmission of the rocker arm 6, thereby realizing the function of tightening and loosening the clamp plate 5.
[0023] The horizontal cross section of the clamping plate 5 is a “C”-shaped structure. When the clamping plate 5 is loosened, the rocker arm 6 is embedded in the “C”-shaped structure of the clamping plate 5 .
[0024] One end of the rocker arm 6 is rotatably connected to the clamp plate 5 , and the shaft pin 7 passes through both ends of the “C”-shaped structure of the clamp plate 5 and one end of the rocker arm 6 to achieve rotatable connection.
[0025] The other end of the rocker arm 6 is rotatably connected to the nut 8, and the side end of the nut 8 is rotatably connected to the other end of the rocker arm 6 through an axle pin 7. A groove 9 is provided on the splint 5. When the rocker arm 6 is embedded in the splint 5, the axle pin 7 on the nut 8 is embedded in the groove 9.
[0026] When the nut 8 connected at both ends of the same rocker arm 6 is higher than the shaft pin 7, the nut 8 is a forward threaded nut.
[0027] When the nut 8 connected at both ends of the same rocker arm 6 is lower than the axle pin 7, the nut 8 is a reverse threaded nut, and the positive and reverse directions of the nut ensure the synchronization of the movement of the rocker arm 6 when the stud 4 rotates, that is, when the stud 4 rotates, all the rocker arms 6 are retracted or extended.
[0028] The stud 4 is rotatably connected to the base 1, including being rotatably connected via a bearing.
[0029] There are multiple clamp components 2, and the multiple clamp components 2 are distributed in a ring array along the extension of the plate 3.
[0030] The shaft pin 7 is rotatably connected to a set of rocker arms 6 .
[0031] The shaft pin 7 is rotatably connected to the two sets of rocker arms 6 .
[0032] In the initial state, the rocker arm 6 is located in the clamp plate 5. At this time, the distance between the multiple clamp assemblies 2 allows the plate 3 to be placed in. After the plate is placed and loaded, the stud 4 is rotated by turning it with a square wrench. Since the side end of the clamp plate 5 is against the plate 3, the nut 8 will not rotate together. Based on the threaded connection between the stud 4 and the nut 8, the nut 8 moves up or down on the stud 4 according to its thread direction. Through the transmission of the rocker arm 6, it pushes the clamp plate 5 to move and press the plate 3.
[0033] When unloading is required, just screw the stud 4 in the reverse direction.
[0034] As required, the base 1 can be fixedly mounted on a transport tool or a lifting tool for transporting the plate 3. To fix the plate through the clamp assembly 2, it is only necessary to twist the stud 4, and there is no need to wrap the rope around the heavy plate multiple times, which is convenient to operate. At the same time, multiple nuts 8 including forward and reverse threads realize the clamp assembly 2 to be pressed, and multiple clamp assemblies 2 are used, which is more secure and not easy to loosen compared to rope fixation.
[0035] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
