The coupler allows simultaneous connection or disconnection.

However, in the conventional multi hydraulic coupler fixing device, the first and second guide members slide on the first and second guide holes and are positioned at the first and second guide hole points of the handle member that are in contact with the first and second guide members. Stress is concentrated. As a result, when a certain period of time passes, wear occurs on the surface where the first and second guide holes of the handle member and the first and second guide members are formed, and clearance occurs at the point where the first and second blocks are joined in close proximity. As a result, there is a problem in that complete tight coupling is not achieved when combining blocks 1 and 2. In addition, if continuous vibration or impact force is generated while stress is applied by being caught through the handle member to maintain the combined state of blocks 1 and 2, damage may occur in the portion where the first and second guide holes of the handle member are formed. There is a problem.

While being transmitted, the second connection block 200 is pulled and moved in the direction of the first connection block 100, and when the first connection block 100 and the second connection block 200 are connected and arranged, it is connected to the control handle 300. The rotation lock driving pin 541 of the locking unit 500 is pressed, and the rotation lock 520 rotates by the torsion spring 530 after the locking state by the rotation lock fixing pin 543 is released. It is inserted into the locking groove 312 of the control handle 300 and maintained in a fixed state. In addition, when it is desired to separate the first connection block 100 and the second connection block 200, the rotation lock 520 is rotated so as to be separated from the locking groove 312 of the control handle 300. Separation is possible by rotating the control handle 300 to move upward to the rotation lock body 510, and maintaining the rotation lock fixing pin 543 in the lock fixing groove 521 of the rotation lock 520. This makes it easy to connect and separate the first connection block 100 and the second connection block 200.
