As shown in fig. 1, the present invention provides a shaver 100, which comprises a handle 10 and a cutter head 20, wherein the cutter head 20 is detachably connected to the handle 10.

As shown in fig. 2, the rear surface of the cutter head 20 is provided with two opposite arc-shaped mounting grooves 21, and the front surface of the cutter head 20 is provided with a blade scraping surface 22.

Referring to fig. 1 and 2, the tool shank 10 includes a housing 11 and a mounting assembly 12, the housing 11 is formed in a handle shape for a user to hold, one end of the housing 11 has an open opening, and the mounting assembly 12 is fixed in the housing 11 and adjacent to the open opening.

The mounting assembly 12 includes a housing 121, two mounting members 122, and a sliding block 123, the housing 121 may include an upper housing 1211 and a lower housing 1212, the sliding block 123 is slidably connected to the housing 121, the sliding block 123 may be fixed with a button 124, and the button 124 is disposed on a surface of the housing 11, so that a user can manipulate the button 124 to slide the sliding block 123 along the housing 121. Two of the mounting members 122 are spaced apart and mirror-imaged within the housing 121.

The mounting member 122 includes a rotatable member 1221 and a projection 1222 extending outwardly from the rotatable member 1221, the projection 1222 is preferably a bearing to mate with the arcuate mounting slot 21 of the tool bit 20 to allow the tool bit 20 to be rotatably coupled to the tool shank 10. The rotating member 1221 is rotatably connected to the housing 121, specifically, a vertical rotating shaft 1223 is disposed at a rear end of the rotating member 1221, and is rotatably connected to the housing 121 via the rotating shaft 1223, and the protrusion 1222 is located at a head end of the rotating member 1221. The sliding block 123, when sliding, contacts the rotating member 1221 and rotates the rotating member 1221.

Specifically, a groove 201 is formed in a recessed manner on an outer side surface and an inner side surface of the rotating member 1221, the groove 201 has a supporting surface 202, the supporting surface 202 may be an inclined surface or an arc surface, a supporting portion 1231 extends from the sliding block 123, the supporting portion 1231 may be cylindrical, the supporting portion 1231 is disposed in the groove 201, the supporting surface 202 is located at the front end of the supporting portion 1231, and when the sliding block 123 moves toward the head end, the supporting portion 1231 contacts with the supporting surface 202, so that the rotating member 1221 is forced to rotate around the rotating shaft 1223.

A pre-load spring 1224 may be connected to the rotating member 1221, and when the button 124 is not manipulated by an external force, the pre-load spring 1224 pre-loads the rotating member 1221 such that the projection 1222 is positioned in the arc-shaped mounting groove 21. In particular, in the present embodiment, both ends of the pre-tightening spring 1224 are respectively connected to the rotating members 1221 of the two mounting members 122, when no external force is applied, the pre-tightening spring 1224 pre-tightens the two rotating members 1221 at the same time, so that the pads of the two rotating members 1221 are respectively placed in the arc-shaped mounting grooves 21, and when the button 124 is pushed by the external force, the two rotating members 1221 simultaneously overcome the elastic force of the pre-tightening spring 1224 to separate the pads from the arc-shaped mounting grooves 21, so that the tool bit 20 is removed from the tool holder 10.

As shown in fig. 2 and 3, the tool shank 10 may further include an elastic member 13, a sliding seat 23 is disposed on a back surface of the tool bit 20, when the tool bit 20 is mounted on the tool shank 10, the elastic member 13 contacts the sliding seat 23 of the tool bit 20, when the tool bit 20 rotates relative to the tool shank 10, the elastic member 13 may provide a restoring force to the tool bit 20, and when an external force for rotating the tool bit 20 is released, the elastic member 13 may restore the tool bit 20 to an initial position.

Specifically, the elastic element 13 may include a top block 131 and a spring 132. One end of the spring 132 may be connected to the housing 121 and the other end to the top block 131, or one end of the spring 132 may be connected to the sliding block 123 and the other end to the top block 131.

The end of the top block 131 may be a slope 1301, and the sliding seat 23 includes a first connection surface 231 and a second connection surface 232, wherein the first connection surface 231 and the second connection surface 232 are connected such that a connection part 233 protrudes toward the top block 131. It is understood that the surface of the sliding seat 23 adjacent to the top block 131 may be a cambered surface. When the cutter head 20 is not externally applied, the first connection surface 231 is in contact with the inclined surface 1301, when the cutter head 20 rotates, the first connection surface 231 is gradually out of contact with the inclined surface 1301, and the second connection surface 232 presses the top block 131, so that the spring 132 is compressed, the cutter head 20 can be sensed to be tightly contacted with the skin surface during shaving, and when the cutter head 20 is not externally driven to rotate, the spring 132 drives the top block 131 to move towards the head end, so that the cutter head 20 is forced to return to the initial state.

The top block 131 includes a limiting portion 1311 and a connecting portion 1312, the connecting portion 1312 is used for connecting the spring 132, and the limiting portion 1311 can limit sliding relative to the housing 121, so that the top block 131 is guided to slide, and the top block 131 is prevented from deviating from the moving direction and being separated from the sliding seat 23.

Throughout the description and claims of this application, the words "comprise/comprises" and the words "have/includes" and variations of these are used to specify the presence of stated features, values, steps or components but do not preclude the presence or addition of one or more other features, values, steps, components or groups thereof.
