Through the transmission of the pulley group, the No. 1 motor 29 can drive the two ball screws 30 to rotate simultaneously, and the lifting seat 13 is driven to rise and fall by the simultaneous rotation of the two ball screws 30. The pressure block 15 rises and falls with the lifting seat 13 to perform strength detection on the optical cable junction box; The support frame 19 is fixed on the placement table 21, and two clamping assemblies 50 are symmetrically arranged on the front and back sides of the placement table 21. The clamping assembly 50 includes two winding assemblies symmetrically installed on the placement table 21, and the winding assembly includes a storage box 52. A No. 1 pulley 53 is rotatably installed in the storage box 52. The No. 1 pulley 53 is fixed to the motor shaft of the No. 2 motor 51, and the No. 2 motor 51 is fixed to the storage box 52. The two No. 1 pulleys 53 are wound with the same clamping belt 59, and the clamping belt 59 is pulled by the two No. 1 pulleys 53 and is arranged horizontally between the two storage boxes 52. After the optical cable junction box is placed on the support roller 18, the clamping belt 59 is loosened by the winding assembly, and then the clamping belt 59 is put on the optical cable junction box.

The lead screw 57 is driven by a power assembly. When the optical cable junction box is placed in, the two winding assemblies move away from each other for easy placement. After the optical cable junction box is placed in, the two winding assemblies move close to each other to the bottom of the optical cable junction box, which can drive the clamping belt 59 to clamp at least three sides of the optical cable junction box at the same time (see the attached manual).
