[0002] The watch strap is the part of the watch that is connected to the wrist and used to fix the watch on the wrist. The materials used to make the watch strap are varied, including leather such as cowhide, pigskin, crocodile skin, as well as stainless steel, titanium alloy, gold, silver, copper, ceramic and other materials. At present, ceramic and metal watch straps are composed of a series of watch strap modules connected together, and the watch strap modules are connected by steel pins or screws. Because consumers' wrists vary in size, watch straps are produced according to the larger size of the wrist. Therefore, after purchasing a watch, most consumers need to disassemble a certain number of watch strap modules according to the size of their wrists in order to fit their wrists. If the length of the watch strap needs to be shortened, special tools need to be used to remove the steel pins or screws to remove the watch strap modules. It is troublesome and difficult for ordinary consumers to adjust the length of the watch strap, especially in today's prevalence of online shopping and live shopping. People need to be able to adjust the length of the watch strap themselves after purchasing a watch, so that they can wear the purchased favorite watch as soon as possible. In order to solve the problem that consumers can easily disassemble the watch strap modules and adjust the length of the watch strap after purchasing a watch, so as to wear the watch on their hands appropriately, a five-bead watch strap tool-free length adjustment structure is proposed.
