Detailed Description
The present invention will be further described with reference to the following examples.
Example 1
As shown in figure 1, the cam scissors device capable of being quickly disassembled and assembled comprises scissors 1, a lever 2, a spring 3, a transmission shaft 4 of a weaving machine and a cam mechanism; the cam mechanism is sleeved on the transmission shaft 4 of the weaving machine; one end of the scissors 1 is fixedly arranged, and the other end is movably arranged; one end of the lever 2 is matched with the cam mechanism, and the other end of the lever is matched with the movable end of the scissors 1; the spring 3 is arranged at one end of the lever 2 in a matching way and is arranged below the cam mechanism; the cam mechanism comprises a fixed block 5 and a cam block 6; the fixed block 5 and the cam block 6 are fixedly arranged on the transmission shaft 4 of the weaving machine through bolts. The cam mechanism of the device comprises a fixed block 5 and a cam block 6 which are fixedly arranged on the transmission shaft 4 of the weaving machine through bolts, so that the device is convenient to disassemble and assemble, and the damage to the transmission shaft 4 of the weaving machine is reduced.
