The two clamp pushing assemblies 2 can enable the extrusion blocks 25 to move towards the two ends of the parallel groove clamp 6, so that the position of the parallel groove clamp 6 is limited. As shown in fig. 8, the wire clip pushing assembly 2 comprises a first base 21, a first handle 22, a crank arm 23, a push rod 24 and an elastic extrusion block 25, wherein the end part of the first handle 22 is connected with the first base 21 in a shaft way, one end of the crank arm 23 is connected with the first handle 22 in a shaft way, the other end of the crank arm is connected with the push rod 24 in a shaft way, the first base 21 is provided with a through hole, the push rod 24 is connected with the extrusion block 25 after penetrating through the through hole, the first handle 22 is swung, and the crank arm 23 drives the push rod 24 to slide in the through hole so that the extrusion block 25 longitudinally moves to extrude and limit the parallel groove wire clip 6.

The extrusion block 25 may be selected to be a rubber material, particularly polyurethane rubber, and the extrusion block 25 has an elastic function to absorb external pressure or impact force by extrusion deformation and convert it into internal energy, thereby protecting other objects or systems from damage. Specifically, when external pressure is applied to the squeeze block 25, the squeeze block 25 is compressively deformed due to its deformable property, and the pressure is dispersed to various portions of the entire squeeze block 25. Once the external pressure is removed, the extrusion block 25 returns to its original shape and volume by restoring its original elasticity, and this extrusion deformation and elastic restoration process enables the extrusion block 25 to slow down or eliminate the impact of the external pressure on the parallel groove clamp 6, thereby protecting it from abrasion.
