By arranging the hook opening 417, the integral appearance of the body shell 3 is ensured, and the hook connection and separation of the hook 42 and the chute 41 are facilitated. When the cutter head assembly 1 is assembled, the hooks 42 hinged on both sides of the mounting seat 2 can be inserted into the hook openings 417, and after entering the sliding grooves 41, since the vertex of the first guiding inclined plane 415 exceeds the center line of the hook openings 417 and is close to one side of the sliding-out channel 414, after the hooks 42 contact with the first guiding inclined plane 415, the hooks 42 are blocked by the first guiding inclined plane 415, and only can enter the sliding-in channel 412 along the first guiding inclined plane 415, and enter the locking channel 413 through the sliding-in channel 412 to be hooked with the hook grooves 4111 of the limiting blocks 411, so that the mounting seat 2 and the housing 3 form a mechanical fixed connection. When the cutter head assembly 1 is disassembled, the vertex of the second guiding inclined surface 416 exceeds the center line of the hook groove 4111 and is close to one side of the slide-in channel 412. When the mounting seat 2 and the hook 42 are displaced downwards by manually pressing the cutter head assembly 1, the end of the hook 42 contacts with the second guiding inclined surface 416, and is blocked by the second guiding inclined surface 416, can only displace towards one side of the sliding-out channel 414 along the second guiding inclined surface 416, and enables the hook 42 to slide out of the sliding-out channel 414 under the elastic force of the elastic element 5; and then is separated from the shell 3 through the hook opening 417, thereby realizing the disassembly of the cutter head component 1, being convenient for the independent cleaning and the cleaning maintenance of the cutter head component 1 and the shell 3, effectively avoiding the propagation of bacteria or germs in the cutter head component 1 and the shell 3 after long-time use, and ensuring the sanitation and the safety of the shaver. In the in-service use process, stopper 411 below is equipped with the hook groove 4111 that is major arc form and makes stopper 411 bottom form the swallow-tail form, can not only guarantee hook groove 4111 and pothook 42's hook firm in connection like this, prevents that pothook 42 from droing, and in addition, the swallow-tail form inclined plane of hook groove 4111 both sides just can play the guide effect when installation and dismantlement, makes things convenient for that pothook 42 is quick to be hooked with hook groove 4111 mutually and is connected and pothook 42 breaks away from. In factIn the process of production and assembly, the hook 42 is fixed with the hinge shaft on the mounting base 2 in a clearance fit manner, so that the end of the hook 42 can slightly deviate in the radial direction while the hook 42 is ensured to be rotatable in the axial direction.

In order to prevent the hook 42 from retracting backwards after entering the sliding channel 412 along the first guiding inclined surface 415, a first stopping block 418 is arranged in the sliding channel 412, the upper end surface of the first stopping block 418 is in an inclined slope shape, the front end is positioned at the joint of the lower point of the first guiding inclined surface 415 and the sliding channel 412, the tail end is positioned at the intersection of the sliding channel 412 and the locking channel 413, and the end surface of the tail end is flush with the side wall of the hook groove 4111 of the limiting block 411 and forms a first stopping surface 4181; by arranging the first anti-return block 418 with a slope at the intersection of the slide-in channel 412 and the locking channel 413, when the cutter head assembly 1 is installed, the installation base 2 and the hook 42 synchronously move downwards to enter the slide-in channel 412 by pressing the cutter head assembly 1 with a hand, the hook 42 can only slide along the first guide slope 415 and enter the slide-in channel 412 due to the blocking of the first guide slope 415, after entering the slide-in channel 412, the hook 42 moves along the slope of the upper surface of the first anti-return block 418 under the influence of the slope of the first anti-return block 418, the end of the hook 42 is gradually lifted, and after the end of the hook 42 passes over the top point of the slope, the end of the hook 42 resets and enters the intersection of the slide-in channel 412 and the locking channel 413. At this time, if the external control force disappears suddenly due to the blocking of the first anti-backing surface 4181, the hook 42 will not disengage from the sliding slot 41, and because the first anti-backing surface 4181 is inclined and level with the side wall of the hook slot 4111 of the limiting block 411, the cutting head assembly 1 and the mounting base 2 will return upward under the elastic force of the elastic member 5, and the end of the hook 42 will slide into the hook slot 4111 of the limiting block 411 along the inclined first anti-backing surface 4181 under the driving of the elastic force, thereby completing the assembly of the cutting head assembly 1.

In order to ensure the smooth detachment of the cutter head assembly 1, a second retaining block 419 is arranged below the limiting block 411, the upper end surface of the second retaining block 419 is in an inclined slope shape, the front end of the second retaining block 419 is flush with the bottom plane of the locking channel 413, the rear end of the second retaining block 419 is located at the intersection of the locking channel 413 and the sliding-out channel 414, and the end surface of the tail end of the second retaining block is flush with the side surface of the limiting block 411 to form a second retaining surface 4191.
