Abstract

The invention relates to a rope puller. The rope puller comprises a body, a rotation shaft arranged on the body, a rope winding disc fixed to the rotation shaft, a pull rope wound around the rope winding disc, and a rocker driving the rotation shaft to rotate. The rope puller is characterized in that the body is further provided with a stop device for locking the pull rope to the needed length, and a reset spring promoting reverse rotation of the rotation shaft; and meanwhile the body is provided with a rapid locking device for positioning the body on a crossbow arm. Compared with the prior art, the rope puller can be rapidly installed on the crossbow arm during using, the pull rope can be conveniently positioned on the needed length through cooperation of a stop arm and a ratchet wheel, meanwhile, a bowstring can be conveniently and easily pulled to the tensioned state through driving of the rocker and cooperation of a one-way bearing, the ratchet wheel and a pallet, and therefore usage is very convenient; and the structure is novel and compact, and the rope puller can serve as an independent component to be used on various crossbows.

Description

technical field [0001] The invention belongs to the technical field of bow and crossbow supplies, and in particular relates to a rope puller. Background technique [0002] As a kind of cold weapon in ancient times, crossbow is mainly composed of crossbow arm, crossbow, bow string and crossbow machine, etc. It has the advantages of long range, high hit rate and relatively low requirements for users. Nowadays, in some special fields, people still use this kind of equipment, but in order to achieve the predetermined range, first of all, they need to have enough force to pull the bowstring, otherwise the power to pull the crossbow is not enough, and naturally it cannot reach the specified range. The range is standard, so this inconveniences some less powerful users. [0003] In order to overcome the above defects, the utility model patent "Strong Crossbow Rope Shooter" with the authorized notification number CN2840429Y discloses a crossbow structure, including a plate spring gr...
