reset quickly, preparing for the next pushing, when the two pushing blocks 26 slide relatively,The stopper 31 slides along the L-shaped guide plate 18, and the spring 30 is in a compressed state, when the stopper 31 slides to the opening of the guide groove 20, the stopper 31 slides off the L-shaped guide plate 18 under the elastic force of the spring 30, and the inclined surface of the stopper 31 is in close contact with the L-shaped guide plate 18, at this time, the top of the stopper 31 no longer blocks the wire blocking block one 32 or the wire blocking block two 33, thereafter, the wire blocking block one 32 and the wire blocking block two 33 are in close contact and locked, when the two pushing blocks 26 are reset, the inclined surface of the stopper 31 slides upward again under the extrusion of the L-shaped guide plate 18 and slides onto the L-shaped guide plate 18, at this time, the spring 30 is compressed again, the wire blocking block one 32 and the wire blocking block two 33 sliding into the pushing block 26 are limited by the stopper 31, so that the wire blocking block one 32 and the wire blocking block two 33 are prevented from being separated from the pushing block 26 during movement, when the wire blocking block one 32 and the wire blocking block two 33 are pushed by the pushing block 26 and in close contact, the lock core 34 on the wire blocking block one 32 slides into the clamping groove 35 of the wire blocking block two 33, during this process, the lock core 34 first contacts and extrudes the clamping block 40, so that the clamping block 40 slides into the fixed sleeve two 38 and compresses the spring two 39, until the lock core 34 slides away from the clamping block 40, under the elastic force of the spring two 39, the clamping block 40 pops out and clamps the lock core 34, thereby achieving locking of the wire blocking block one 32 and the wire blocking block two 33, when the staff needs to disassemble the wire blocking block one 32 and the wire blocking block two 33 after finishing the wire laying, the fixed sleeve two 38 is driven to slide in the storage groove 36 by rotating the screw outward, so that the clamping block 40 slides and separates from the lock core 34, thereby facilitating the staff to disassemble and separate the wire blocking block one 32 and the wire blocking block two 33, a single cable can be guided first by the guide block one 4, so that the plurality of cables can be guided to the guide block two 6, and the half number of cables on the wire laying frame 1 can be concentrated and guided by the guide block two 6, so as to facilitate subsequent movement to the guide block three 21.
