DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] The fixed knife assembly 2 is connected to the connecting assembly 3. When the connection is completed, the fixed knife assembly 2 and the connecting assembly 3 are limited by the quick release mechanism 4, so that the fixed knife assembly 2 and the connecting assembly 3 are connected together and will not separate without the action of external force.

[0027] like Figure 2-Figure 4 As shown, the inner wall of the fixed knife 21 is threadedly connected with a bolt 22, and the outer wall of the bolt 22 is threadedly connected with a fixed knife fixing block 23. The middle part of the fixed knife fixing block 23 is a hollow semicircle, and the left and right parts of the fixed knife fixing block 23 are irregular strip-shaped solid blocks.

[0028] The fixed knife 21 is fixedly connected to the fixed knife fixing block 23 by means of the bolt 22 , and then the fixed knife fixing block 23 can be quickly connected to the connecting assembly 3 , and then the fast release mechanism 4 is used to limit and fix them.

[0029] like Figure 2-Figure 5 As shown, a through slot 32 is opened in the middle of the adjusting rod bracket 31, and the inner wall of the through slot 32 is plugged into the outer wall of the fixed knife fixing block 23. The shape of the through slot 32 is the same as that of the fixed knife fixing block 23, and the size of the through slot 32 is greater than or equal to the size of the fixed knife fixing block 23.

[0030] The outer wall of the fixed knife fixing block 23 is plugged into the through slot 32 formed on the outer wall of the adjusting rod bracket 31 , so that the outer wall of the fixed knife fixing block 23 is completely plugged into the inner wall of the through slot 32 until it cannot be plugged any further.

[0031] like Figure 4 , Figure 6As shown, the outer wall of the copper rivet 41 is rotatably connected to the locking wrench 42, the outer wall of the locking wrench 42 is slidably connected to the outer wall of the adjusting rod bracket 31, the outer wall of the locking wrench 42 is slidably connected to the inner wall of the fixed knife fixing block 23, the outer wall of the copper rivet 41 is fixedly connected to the rubber clamp 43 in a circular array, the outer shape of the rubber clamp 43 is semi-spherical, and the outer wall of the rubber clamp 43 is clamped with the inner wall of the locking wrench 42.

[0032] After the outer wall of the fixed knife fixing block 23 is plugged into the through slot 32 formed on the outer wall of the adjusting rod bracket 31, the locking wrench 42 is rotated to the right to the maximum distance. In this process, when the locking wrench 42 is rotated, the inner wall of the locking wrench 42 contacts the outer wall of the rubber block 43. Because the rubber block 43 is made of rubber, when the inner wall of the locking wrench 42 squeezes the rubber block 43, the rubber block 43 is deformed and forms resistance at the same time. When the locking wrench 42 is rotated to the maximum distance, the locking wrench 42 is locked. The wrench 42 no longer moves, and the rubber clamping block 43 returns to its circular shape and engages with the inner wall of the locking wrench 42, thereby limiting the locking wrench 42 and preventing the locking wrench 42 from rotating. At this time, the locking wrench 42 cannot be further rotated without the action of external force. At this time, the outer wall of the locking wrench 42 is plugged into the inner wall of the hollow semicircular shape in the middle of the fixed knife fixing block 23, thereby limiting the fixed knife fixing block 23 and preventing the fixed knife fixing block 23 from escaping from the inner wall of the through groove 32, thereby preventing the fixed knife 21 from falling off, achieving the effect of quick replacement.

[0033] The working principle of the utility model is as follows: when the fixed blade 21 needs to be replaced, the locking wrench 42 is first turned to the right until it cannot be turned, and then the original fixed blade 21 of the electric hair clipper body 1 can be removed, and then the fixed blade 21 to be replaced can be installed, and the fixed blade fixing block 23 is driven by the fixed blade 21 to make the outer wall of the fixed blade fixing block 23 and the through groove 32 provided on the outer wall of the adjusting rod bracket 31 be plugged, so that the outer wall of the fixed blade fixing block 23 is completely inserted into the through groove 32. The inner wall of the fixed blade 21 is connected to the inner wall of the through groove 32 until it can no longer be inserted. At this time, the outer wall of the fixed blade 21 contacts the outer wall of the movable blade 11, and then the locking wrench 42 can be turned again to the right to the maximum distance. In this process, when the locking wrench 42 is rotated, the inner wall of the locking wrench 42 contacts the outer wall of the rubber block 43. Because the rubber block 43 is made of rubber, when the inner wall of the locking wrench 42 squeezes the rubber block 43, the rubber block 43 is deformed, and at the same time The locking wrench 42 is not able to rotate further without external force. At this time, the outer wall of the locking wrench 42 is plugged into the inner wall of the hollow semicircular middle part of the fixed knife fixing block 23, thereby limiting the fixed knife fixing block 23 and preventing the fixed knife fixing block 23 from rotating. The fixed block 23 is disengaged from the inner wall of the through groove 32, thereby preventing the fixed knife 21 from falling, achieving the effect of quick replacement. Later, when the fixed knife 21 needs to be cleaned, the locking wrench 42 can be rotated so that the outer wall of the locking wrench 42 is no longer plugged into the inner wall of the fixed knife fixing block 23. Then the fixed knife 21 can be removed and cleaned, avoiding affecting the circuit inside the electric hair clipper body 1 during rinsing, achieving the effect of convenient cleaning, thereby greatly improving the user experience.
