查，市面上的砂帶機為求砂帶經長時間使用後可被替換或可依據使用需求搭配不同的砂袋，當前砂帶機的結構多被設計可因應替換砂帶的需求來實施，相關結構可參CN 110216557A、US 10618139B以及CN 208945846U等專利所揭。According to the investigation, the abrasive belt machines on the market require that the abrasive belt can be replaced after a long period of use or can be equipped with different sand bags according to the use needs. The current structure of the abrasive belt machine is mostly designed to meet the needs of replacing the abrasive belt. Related structures can be disclosed in patents such as CN 110216557A, US 10618139B and CN 208945846U.

惟，根據CN 110216557A及US 10618139B專利所揭圖面可發現，習用砂帶機透過在砂帶機本體上設置可便於拆除砂帶的快拆組件，然而習用結構多是令砂帶設置於砂帶裝設座上，而砂帶裝設座上分別設置兩貫穿孔，該快拆組件穿入兩貫穿孔中並於兩貫孔的其中一側設置有操作件，並於兩貫孔的另一側設有止擋塊，實施時快拆結構透過操作撥片，令該止擋塊受作用而推動該砂帶裝設座朝面對撥片方向位移，進而令該砂帶裝設座與該砂帶機本體產生迫緊，如此使得砂帶得以被安裝於該砂帶機本體上。當擬拆除砂帶裝設座時，則再次操作撥片，使得止擋塊不再限制砂帶裝設座，令砂帶裝設座得與砂帶機本體分離。惟，習用快拆結構於組裝時必須留意零件的組裝方向而無法快速固定砂帶裝設座。另外，CN 208945846U專利雖是透過螺紋鎖固的方式來組接砂帶裝設座，然此操作方式無法快速地固定砂帶裝設座。However, according to the drawings disclosed in the CN 110216557A and US 10618139B patents, it can be found that the conventional belt sander can be easily removed by installing the quick release assembly on the sanding belt machine body.
