Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 4.

A puncture wire clamp comprises an upper clamp body 1 and a lower clamp body 2, wherein the upper clamp body 1 and the lower clamp body 2 are buckled together through a fastening component 3, an arc-shaped inner concave cavity is arranged on the lower clamp body 2, the middle part of the inner concave cavity is arched outwards towards the inner concave cavity to form a boss 20, the inner concave cavity is divided into two threading grooves 21, a plurality of threading teeth 22 are distributed in the threading grooves 21, a groove 10 is arranged on the end face of the upper clamp body 1 corresponding to the boss 20, the upper clamp body 1 is divided into two clamping areas 11 by the groove 10, two rows of first fixing teeth 12 are arranged on the clamping areas 11, a strip-shaped groove 13 is arranged between the two rows of fixing teeth, a tooth row 14 is inserted in the strip-shaped groove 13 and comprises a cross rod 140 with a plurality of through holes 141, a second fixing tooth 142 is inserted in the through hole 141, the second fixing tooth 142 comprises a base 143 with a cross section larger than that of the through hole 141 and a tooth tip 144, an internal groove 145 is formed in the second fixed gear 142, and a spare gear 146 is formed in the internal groove 145. The fastening component 3 comprises a screw rod 30 and a nut 31, the screw rod 30 is matched with the nut 31 after penetrating through the upper clamp body 1 and the lower clamp body 2 respectively, the screw rod 30 is provided with an end part, a gasket ring 32 and a stop block 33 are sleeved on the screw rod 30, and the gasket ring 32 and the stop block 33 are positioned between the end part of the screw rod 30 and the upper clamp body 1.
