Description

A band mechanism and band tensioner for band tensioner Technical Field The application relates to the field of tighteners, in particular to a lacing mechanism for a lacing tensioner and the lacing tensioner. Background The strap tensioner is used as a common tool in the fields of logistics packaging, cargo fixing and outdoor equipment, and is used for applying tension to straps (such as nylon straps, steel belts or plastic straps) through mechanical force and locking, so that the stability of cargoes in transportation or storage is ensured, and loosening or displacement caused by vibration and impact is prevented. The current strap tensioner generally comprises a base, a main shaft, a driving arm and a ratchet wheel assembly, wherein the base is rotationally connected with the main shaft, the driving arm is rotationally connected with the main shaft, a tightening groove is formed in the main shaft, a braid can be arranged in the tightening groove in a penetrating mode, the ratchet wheel assembly is arranged on the main shaft, and when the driving arm rotates unidirectionally, the driving arm drives the main shaft to rotate through the ratchet wheel assembly to tighten the braid, and meanwhile the main shaft is kept not easy to rotate and loosen to tighten the braid. For the related art, after goods are fixed, the redundant long ends of the braid are not fixed, and knotting treatment is generally carried out, but after the bound goods are scattered, the knotted and contracted long ends of the braid are easy to loosen the knot to generate drift, and the scattered braid has higher potential safety hazard. Disclosure of Invention The application provides a strap mechanism for a strap tensioner and the strap tensioner for accommodating and fixing redundant long ends of a strap. The application provides a strap mechanism for a strap tensioner and the strap tensioner, which adopt the following technical scheme: The clamping assembly comprises a clamping frame, a clamping torsion spring and a clamping body, wherein the clamping frame is rotationally connected to a driving arm of the strap tensioner, one end of the clamping torsion spring is abutted to the driving arm of the strap tensioner, the other end of the clamping torsion spring is abutted to the clamping frame, the clamping body is fixedly arranged at one end of the clamping frame, and when the clamping assembly clamps and fixes redundant webbing, the clamping body clamps and fixes the redundant webbing to the strap tensioner; the fixing component comprises one or two fixing rods, the fixing rods are in sliding fit with the driving arms of the strap tightener, the clamping frame rotates to a set position towards the driving arms far away from the strap tightener, and when the clamping torsion spring drives the clamping frame to rotate and reset towards the driving arms close to the strap tightener, the fixing rods are in butt joint with the clamping frame, so that the clamping frame cannot reset. Through adopting above-mentioned technical scheme, when band mechanism carries out the centre gripping fixed to unnecessary meshbelt, the clamping frame rotates to the settlement position towards the actuating arm direction of keeping away from the band strainer, when the centre gripping torsional spring drives the clamping frame and rotates when restoring to the throne towards the actuating arm that is close to the band strainer, dead lever and clamping frame butt, so that the clamping frame can not restore to the throne, follow the unnecessary meshbelt rolling with the band strainer, the fixed subassembly unblock, thereby make the centre gripping torsional spring drive clamping frame restore to the throne until the clamping body is fixed in the band strainer with unnecessary meshbelt centre gripping, thereby accomplish the centre gripping fixed to unnecessary meshbelt, after fixed goods, unnecessary meshbelt long head is not fixed, generally can tie up the processing, but after the goods of ligature is dispersed, the meshbelt long head of knot harvest loosens the knot easily and appears the drift, and the meshbelt that drifts has the problem of higher potential safety hazard. Optionally, the fixed subassembly still includes the impeller, impeller quantity is the same with the dead lever is fixed, the impeller slides the drive arm that cooperates in band tensioning ware, just impeller and dead lever fixed connection, when pressing the impeller, the impeller drives the dead lever slides, the fixed subassembly unblock, so that the holder resets. Optionally, the fixed subassembly still includes reset spring, reset spring sets up in the actuating arm of band tensioning ware, reset spring is connected with the dead lever, just reset spring is used for driving the dead lever and resets, so that when centre gripping torsional spring drives the holder towards the actuating arm rotation reset that is close to the band tensioning ware, dead lever and holder butt. Optionally,
