This educational model is designed for teachers, students, classrooms, workshop, helping learners connect textbook concepts with real movement they can see and follow.As a mechanism demonstration kit, demonstrates motion is passed through different parts of a mechanical system, so students can observe the working process instead of just memorizing concepts. The mechanical transmissions model includes several transmissions types, including a Gear Drives model and a chain drive model, which makes comparison lessons much more intuitive and practical.Its open structure and clearly visible components help confusion during teaching, while the compact desktop format keeps it convenient for daily use. The set also supports a broader understanding of speed change, direction transfer, and transmissions relationships, making each demonstration more meaningful in real learning situations.Whether you are explaining a teaching unit at the front of the classroom or letting students investigate the mechanism closely, this model turns concept into a clear, interactive experience. It is a useful choice for building curiosity, strengthening comprehension, and making mechanical principles feel much more approachable.","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/f45af916-435a-49c5-95cc-9408c2011fc4.jpg?v=1786024016","href":"/product/wp-dcd-10001089505.html","buy_url":"https://uecyem-u1.myshopify.com/products/wp-dcd-10001089505","buy_url_source":"shops.shop_domain + product.handle","seller_name":"uecyem-u1.myshopify.com","seller_url":"https://uecyem-u1.myshopify.com/","return_policy_url":"https://uecyem-u1.myshopify.com/policies/refund-policy","media":[{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/f45af916-435a-49c5-95cc-9408c2011fc4.jpg?v=1786024016","alt":"Gear Drives Model Visual Demonstration Chain Drive Model Easy to Use Mechanism Demonstration Kit for Students","position":0},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/4bab066b-1b84-4f14-8bcc-a865ad142c69.jpg?v=1786023355","alt":"Gear Drives Model Visual Demonstration Chain Drive Model Easy to Use Mechanism Demonstration Kit for Students","position":1},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/8aa23a41-a335-4787-9333-77c83bdcd965.jpg?v=1786023511","alt":"Gear Drives Model Visual Demonstration Chain Drive Model Easy to Use Mechanism Demonstration Kit for Students","position":2},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/48096e79-83ad-4f90-b08e-b19fe2eced70.jpg?v=1786023354","alt":"Gear Drives Model Visual Demonstration Chain Drive Model Easy to Use Mechanism Demonstration Kit for Students","position":3},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/248b4d95-869a-41af-a9dd-d9af8f065b64.jpg?v=1786023638","alt":"Gear Drives Model Visual Demonstration Chain Drive Model Easy to Use Mechanism Demonstration Kit for Students","position":4},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/3adb1510-4439-499b-aeb5-306565c7fae3.jpg?v=1786024490","alt":"Gear Drives Model Visual Demonstration Chain Drive Model Easy to Use Mechanism Demonstration Kit for Students","position":5},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/c5060635-26a5-4090-b2cf-245d1ee0835d.jpg?v=1786023363","alt":"Gear Drives Model Visual Demonstration Chain Drive Model Easy to Use Mechanism Demonstration Kit for Students","position":6},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/63131c80-0684-45b7-94d8-d6fe5a4b926c.jpg?v=1786023369","alt":"Gear Drives Model Visual Demonstration Chain Drive Model Easy to Use Mechanism Demonstration Kit for Students","position":7},{"url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/d8cfe18a-204a-4ad8-a065-338884a3a265.jpg?v=1787392265","alt":null,"position":8}],"related":[{"handle":"wp-dcd-10001255857","title":"Chip Card Storage Box, Flip-Top Card Organizer for Game Cards, Dustproof and Moisture-Proof","category":"爱好","price":"$1.05","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/O1CN01oMakGw1NVr8uFQl8x__2215925121576-0-cib.jpg?v=1787388464","sku":"dcd-30003572967","href":"/product/wp-dcd-10001255857.html"},{"handle":"wp-dcd-10001228061","title":"photo card display stand","category":"爱好","price":"$2.72","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/791c7dbca96543d1842677dbfc804ee5.png?v=1786030490","sku":"dcd-30003480410","href":"/product/wp-dcd-10001228061.html"},{"handle":"wp-dcd-10001187202","title":"Animal Bathtub Figurine Soothing Style Cute Animal Desk Decoration Handmade Feel Figurine for Office","category":"爱好","price":"$2.92","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/b639ef4a-a4d5-4694-99f1-6f75f0c801af.jpg?v=1786029287","sku":"dcd-30003355924","href":"/product/wp-dcd-10001187202.html"},{"handle":"wp-dcd-10001187198","title":"Tea Pet Frog Wealth Symbol Table Ornament Handmade Decor for Gift Display","category":"爱好","price":"$22.22","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/7980da8f-53b9-487d-a183-6688b671424d.jpg?v=1786029292","sku":"dcd-30003355919","href":"/product/wp-dcd-10001187198.html"}]}}
