The invention provides a puller. The puller solves the technical problems that an existing puller is too simple in structure, accordingly when used, the puller cannot be quickly locked on zipper teethand the anti-theft effect is poor. The puller comprises a zipper base, the zipper base comprises an upper cover plate, a lower cover plate and a support core, and the upper cover plate is connected with the lower cover plate through the support core; the puller further comprises a pull piece, a screw rod, a bearing and a locking block; the upper portion of the upper cover plate is provided with aprotruding mounting part, the screw rod is in threaded connection with the mounting part, a bearing inner ring is connected with the lower end of the screw rod, a bearing outer ring is connected withthe locking block, the locking block is located in the zipper base, the pull piece is arranged at the upper end of the screw rod, and the pull piece is located outside the zipper base. The puller hasthe advantages of being good in anti-theft effect.
Description
Technical field [0001] The invention belongs to the technical field of zippers, and relates to a slider. Background technique [0002] Zipper is a connecting piece that relies on continuously arranged chain teeth to merge or separate items. It is now widely used in clothing, bags, tents, etc. The zipper is composed of chain teeth, slider, top and bottom stop (front code and back code) or locking parts. The chain teeth are the key part, which directly determines the side pull strength of the zipper. Generally, a zipper has two chain belts, and each chain belt has a row of chain teeth, and the two rows of chain teeth are arranged alternately. The slider clamps the chain teeth on both sides and slides with the help of the pull tabs to make the chain teeth on both sides engage or disengage each other. [0003] After searching, for example, the Chinese Patent Literature discloses a zipper pull head [application number: 201020632267.X; publication number: CN 201860935U]. This zipper ...
