[0015] Fig. 2 This is a partially exploded view of the adjustable fixed blade hair clipper in an embodiment of the present invention;
[0016] Fig. 3 This is an exploded view of the adjustment component and bushing in an embodiment of the present invention. Detailed Implementation
[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0018] like Figs. 1-3 The image shows a preferred embodiment of the present invention. This embodiment of an adjustable-blade hair clipper includes a clipper body 1, a clipper head 2, an adjustment assembly 3, a fastener 4, and a bushing 5.
[0019] The hair clipper head 2 includes a fixed blade 21, a movable blade 22, and a fixed blade holder 23. The movable blade 22 is located above the fixed blade 21 and can reciprocate relative to the fixed blade 21 to achieve cutting. The fixed blade holder 23 is fixedly and slidably connected to the outer shell of the hair clipper body 1, so that the fixed blade 21 can slide back and forth relative to the movable blade 22.
[0020] In this embodiment, the adjustment assembly 3 includes an adjustment rod 31, a latch 32, a latch block 33, and a compression spring 34. The adjustment rod 31 is rotatably connected to the outer shell of the hair clipper body 1 by a fastener 4. The head of the adjustment rod 31 has a first groove 311 and a second groove 312. The latch 32 and the compression spring 34 are disposed in the first groove 311 and can rotate with the adjustment rod 31.
[0021] A compression spring 34 is positioned below the throttle lock 32. The throttle lock 32 has at least two adjacent concave-convex structures 321 and two limiting posts 322 at its bottom for the compression spring 34 to be fitted onto. A throttle block 33 is positioned above the throttle lock 32. The throttle block 33 has a locking structure 331 that engages with the concave-convex structures 321 for limiting. The compression spring 34 causes the throttle lock 32 to always tend to move towards the throttle block 33, and the concave-convex structures 321 always engage with the locking structure 331 for limiting. The length of the locking structure 331 is greater than the length of the concave-convex structures 321, so that the throttle lock 32 can rotate a certain distance relative to the throttle block 33.
[0022] In this embodiment, the fastener 4 is a fixing screw, and a bushing 5 is fitted around it. The top of the side wall of the bushing 5 has a first limiting groove 51. The reciprocating block 33 has a through hole 333 in the middle for the fastener 4 and the bushing 5 to pass through. The reciprocating block 33 has a first limiting block 332 that engages with the first limiting groove 51 and is located on the side wall of the through hole 333. In this way, the reciprocating block 33 is fixedly connected to the fastener 4 and the bushing 5 and will not rotate.
[0023] Meanwhile, in order to prevent the bushing 5 from rotating, the outer shell of the hair clipper body 1 has a fixing groove 11, the fastener 4 is locked in the fixing groove 11, the side wall of the fixing groove 11 is provided with a second limiting block 12, and the bottom of the side wall of the bushing 5 has a second limiting groove 52 that cooperates with the second limiting block 12.
[0024] To limit the rotation angle of the adjusting rod 31, the bottom of the pitch block 33 has a protruding limiting part 334. The width of the limiting part 334 is smaller than the width of the second groove 312. When the adjusting rod 31 is rotating, the limiting part 334 abuts against the side wall of the second groove 312, thereby limiting the adjustment rod 31 from continuing to rotate. The longest adjustment distance of the fixed tool 21 can be changed by setting the width of the limiting part 334 and the width of the second groove 312.
[0025] In this embodiment, the outer shell of the hair clipper body 1 has a guide groove 13, and the top of the fixed blade holder 23 is bent to extend into the guide groove 13. The fixed blade holder 23 has a first sliding hole 231 and a second sliding hole 232. The bottom of the adjusting rod 31 has a sliding block 313 located in the first sliding hole 231. The fastener 4 passes through the second sliding hole 232, and the width of the fastener 4 is smaller than the width of the second sliding hole 232. When the adjusting rod 31 is rotated to one side, the sliding block 313 abuts against the side wall of the corresponding side of the first sliding hole 231, thereby pushing the fixed blade holder 23 to slide along the guide groove 13 to that side.
[0026] The working principle of this embodiment is as follows: the concave and convex structure 321 of the section lock 32 and the locking structure 331 of the section block 33 are in a limiting engagement. When the tail of the adjusting rod 31 is rotated, the section lock 32 moves slightly downward under the action of the compression spring 34 and then moves upward as the adjusting rod 31 rotates, so that the concave and convex structure 321 and the locking structure 331 continue to be in a limiting engagement. Each time the concave and convex structure is rotated through an angle, a crisp clicking sound is produced, which can produce a clear sense of sectioning. Each concave and convex structure that can be rotated represents a gear for adjusting the position of the fixed blade, that is, the specific position of the fixed blade can be adjusted, thereby controlling the length of the haircut.
[0027] When the adjusting rod 31 rotates to the state where the limiting part 334 abuts against the side wall of the second groove 312, it can no longer rotate forward. This sets the number of gears and the longest adjustment distance of the fixed blade 21. While the adjusting rod 31 rotates, the sliding block 313 at the bottom of the adjusting rod 31 abuts against the side wall of the corresponding side of the first sliding hole 231 of the fixed blade holder 23, thereby pushing the fixed blade holder 23 to slide along the guide groove 13 to that side.
