Thus, the connecting member 42 is coupled to the locking block 44 and integrated with the handle 20.

Then, the rotation supporting projections 36 formed on both sides of the cartridge engaging portion 42A are engaged with the respective projection engaging recesses 42B-1 on both sides. At this time, since the rotation support engaging projections 36 are engaged with the respective projection engaging recesses 42B-1, the blade cartridge 30 is rotatable within a predetermined angle, that is, the angle is adjustable.

On the other hand, since each elasticity generating end 42A-3 of the cartridge engaging portion 42A elastically supports the pushing end 36, the blade cartridge 30 always maintains the state before the angle is adjusted. That is, the state before rotation at a predetermined angle is maintained. This is because each of the elastic generating ends 42A-3 elastically presses the pressing end 36. [

In this way, the blade cartridge 30 is engaged with the engaging means 40. That is, it is detachably integrated with the handle 20 by the connecting member 42.

In this state, the user attaches the handle 20 and then brings the multiple blades 32 into contact with the skin to proceed shaving.

When the multiple shaving blades 32 are brought into close contact with the skin and then pulled in one direction, the elastic guard 38 causes the hair to be raised, so that the multiple blades 32 smoothly cut the raised hair.

On the other hand, when the user presses the handle 20 toward the skin, since each elasticity generating end 42A-3 elastically presses the pushing end 36, the blade cartridge 30 has the elasticity generating ends 42A- 3) at a predetermined pressure. Since each of the elasticity generating ends 42A-3 supports the rear surface of the blade cartridge 30 with a predetermined elastic force, when the blade cartridge 30 advances along the bending of the skin, the hair is cut .

When shaving is completed by the above-described procedure and the user moves the separation knob 46 when the user changes the blade cartridge 30, the separation knob 46 overcomes the elasticity of the elastic return edge 44A-4 The elastic latching end 44A-1 is lifted while advancing. That is, when the separation knob 46 advances, the elastic latching end 44A-1 is inserted into the through hole 46B and is guided by the release slope 46D so as to be lifted upward, whereby the elastic latching ends 44A- The handle engagement portion 42B can be disengaged from the lock block 44 because the engagement of the fastening tab 42B-3 on the engagement tab 44A-2 of the blade cartridge 1 is released, The connecting member 42 integrated with the handle 20 can be separated from the handle 20. [

Then, when the advance knob 46 is released, the release knob 46 returns to its original position (reverse) by the elasticity of the elastic returning end 44A-4.

When the connecting member 42 is separated in this way, the connecting member 42 of the new blade cartridge 46 is inserted into the engaging hole 22 and integrated with the handle 20 through the engaging means 40.
