Multi-blade saw hydraulic shaft sleeve convenient to adjust

The utility model relates to the technical field of hydraulic shaft sleeves, and discloses a multi-blade saw hydraulic shaft sleeve convenient to adjust, which comprises a tensioning sleeve, flange plates, a hydraulic mechanism, an adjusting mechanism and a dismounting mechanism, the adjusting mechanism is located in the flange plate, and the dismounting mechanism is located in the adjusting mechanism. According to the multi-blade saw hydraulic shaft sleeve convenient to adjust, the dismounting mechanism is arranged, the inner bolt is matched with the threaded groove, when the pin shaft needs to be taken out to relieve pressure of the hydraulic cavity, the pin shaft can be taken out only by clamping a hexagon bolt head and rotating the inner bolt to be separated from the threaded groove, operation is very easy and convenient, and the practicability is high. And the pin shaft can be taken out without finding a bolt matched with the threaded groove, the pressure adjusting efficiency of the hydraulic shaft sleev
