[0005] By adopting the above technical solution, the nut body is placed in the clamping plate in advance, and the clamping plate is moved along the opening direction of the clamping slot until the fixed plate is in the clamping slot to achieve the clamping connection between the clamping plate and the fixed plate. At this time, only one end of the screw rod needs to be inserted along the through groove and threadedly connected to the nut body. In this process, only a wrench is needed to achieve the threaded connection between the screw rod and the nut body, so that the two semi-ring plates are connected together, which avoids the nut body from falling off. The area of the round block is larger than the opening area of the through groove, so the round block cannot pass through the through groove and can only be on one side of the fixed plate.
[0006] As a further solution of the utility model: the clamping plate is provided with a chamfer at the opening of the clamping slot.
[0007] By adopting the above technical solution, the chamfered corners make it easier for the fixing plate to be clipped into the clip plate.
[0008] As a further solution of the utility model: a placement groove for placing the nut body is provided in the middle of the clamping plate, and the clamping plate is provided with a circular groove located on one side of the placement groove.
[0009] By adopting the above technical solution, the nut body is placed in the placement groove, preventing the nut body from rotating.
[0010] As a further solution of the utility model: the end surface of the round block is provided with a hexagonal groove.
[0011] By adopting the above technical solution, the setting of the hexagonal groove makes it easier to rotate the round block.
[0012] As a further solution of the utility model: the card slot is arranged in an L shape and a limiting plate is arranged at the opening of the card slot.
[0013] By adopting the above technical solution, the stability of the fixing plate in the clamping plate is increased.
[0014] As a further solution of the utility model: a deformation groove is provided on one side of the clamping plate.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] Place the nut body in the clamping plate in advance, move the clamping plate along the opening direction of the clamping slot until the fixed plate is in the clamping slot, and realize the clamping connection between the clamping plate and the fixed plate. At this time, just insert one end of the screw along the through groove and threadedly connect it with the nut body. This process only requires the use of a wrench to achieve the threaded connection between the screw and the nut body, so that the two semi-ring plates are connected together, avoiding the nut body from falling off. The area of the round block is larger than the opening area of the through groove, so the round block cannot pass through the through groove and can only be on one side of the fixed plate.
