If the specific posture changes, the directional indications will also change accordingly.
[0016] In the description of the embodiments, unless otherwise clearly specified and limited, terms such as "set", "connected", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or connected through an intermediate medium, or there can also be a connection inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0017] Such as Figure 1-2As shown in the figure, the quick installation structure of the cloth cutting knife in this embodiment includes a knife seat 1, a blade 2, and a positioning seat 3. The blade 2 is arranged between the knife seat 1 and the positioning seat 3. At the center position of the front end face of the knife seat 1, there is an installation shaft 4. On both sides of the installation shaft 4, there is a connecting groove 5 symmetrically. At the center position of the blade 2, there is an installation hole 6. On both sides of the installation hole 6, there is a connecting hole 7 symmetrically. At the center position of the positioning seat 3, there is a through hole 8. On both sides of the through hole 8, there is a connecting column 9 symmetrically.
[0018] The installation hole 6 is sleeved on the installation shaft 6, and the two connecting holes 7 correspond to the two connecting grooves 5 one by one. The through hole 8 is sleeved on the installation shaft 6, and the two connecting columns 9 respectively pass through the two connecting holes 7 and are connected to the two connecting grooves 5 one by one.
