This utility model features a connecting plate fixedly installed inside the outer casing, a motor fixedly installed at the bottom of the connecting plate, an output shaft fixedly installed at the output end of the motor, a connecting plate fixedly installed above the output shaft, and an eccentric shaft fixedly installed above the connecting plate. When the motor is started, it drives the connecting plate to rotate via the output shaft. Since the eccentric shaft and the connecting plate are fixedly connected, the eccentric shaft rotates with the connecting plate. Simultaneously, because the eccentric shaft is located above the connecting plate but not coaxial, it has a certain eccentric effect. At this time, because the eccentric shaft contacts the push-pull plate, when the eccentric shaft... After the spindle rotates, it will drive the push-pull plate to move. At the same time, the push-pull plate, through the fixed connection between the connecting shaft and the connecting rod, will drive the bottom blade to move left and right, so as to cooperate with the top blade above to achieve the effect of trimming. Since the connecting sleeve is fitted inside the fixed shaft, after trimming, the connecting sleeve can be directly removed from the outside of the fixed shaft.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6 As shown, this utility model provides a surgical site hair trimmer with an easily detachable blade head, including a housing 1. A connecting plate 2 is fixedly installed inside the housing 1. A motor 3 is fixedly installed at the bottom of the connecting plate 2. An output shaft 4 is fixedly installed at the output end of the motor 3. A connecting plate 5 is fixedly installed at the top of the output shaft 4. An eccentric shaft 6 is fixedly installed above the connecting plate 5. A fixing shaft 7 is fixedly installed above the housing 1. A connecting sleeve 8 is sleeved on the outside of the fixing shaft 7. A connecting rod 9 is fixedly installed on the outside of the connecting sleeve 8. A connecting shaft 10 is fixedly installed inside the connecting rod 9. A push-pull plate 11 is fixedly installed on the outside of the connecting shaft 10. A bottom blade 12 is fixedly installed at the end of the connecting rod 9 away from the connecting sleeve 8.

[0024] The starter motor 3 drives the connecting plate 5 to rotate via the output shaft 4. Since the eccentric shaft 6 is fixedly connected to the connecting plate 5, the eccentric shaft 6 rotates with the connecting plate 5. At the same time, since the eccentric shaft 6 is located above the connecting plate 5 but not on the same axis, the eccentric shaft 6 has a certain eccentric effect. At this time, since the eccentric shaft 6 is in contact with the push-pull plate 11, when the eccentric shaft 6 rotates, it will drive the push-pull plate 11 to move. At the same time, the push-pull plate 11 drives the bottom blade 12 to move through the fixed connection between the connecting shaft 10 and the connecting rod 9, thereby enabling the bottom blade 12 to move left and right to cooperate with the top blade 16 above to achieve the effect of trimming.

[0025] The outer casing 1 has a groove 13 inside, a slider 14 is slidably connected inside the groove 13, a top cover 15 is fixedly installed above the slider 14, and a top blade 16 is fixedly installed on the left side of the top cover 15.

[0026] The top blade 16 is located above the bottom blade 12 and the top blade 16 and the bottom blade 12 are staggered. When the bottom blade 12 is moved, it can cooperate with the bottom blade 12 to insert the hair into the middle of the bottom blade 12 and the top blade 16 and cut it, thereby improving the efficiency of hair cutting.

[0027] The slider 14 has an insertion hole 17 inside. Fixing plate 18 and fixing plate 29 are fixedly installed on the front and rear sides of the outer shell 1. Insert rods 20 are inserted into the interior of fixing plate 18 and fixing plate 29. Springs 21 are sleeved on the outside of the insert rods 20. Limiting rings 22 are fixedly installed on the outside of the insert rods 20. Springs 21 are fixedly connected to fixing plate 29 and limiting rings 22. Sealing sleeves 26 are fixedly installed on the left and right sides of the outer shell 1. Parts of the structure of fixing plate 18, fixing plate 29, springs 21 and insert rods 20 are located inside the sealing sleeves 26.

[0028] The insertion rod 20 is inserted into the insertion hole 17. After the slider 14 is inserted into the interior of the outer shell 1 through the sliding action with the slide groove 13, the insertion rod 20 is pulled to the left so that the rightmost side of the insertion rod 20 is located on the left side of the insertion hole 17. After the slider 14 is installed to the bottom of the slide groove 13, the insertion rod 20 is released. At this time, the spring 21 provides elastic force to drive the limiting ring 22 to drive the insertion rod 20 into the insertion hole 17, so that the insertion hole 17 drives the slider 14 to be limited, thereby achieving the effect of fixing the top cover 15.

[0029] The outer casing 1 has a sealing plate 23 fixedly installed inside, a sealing block 25 fixedly installed on the top of the outer casing 1, and a switch 24 slidably connected to the left side of the outer casing 1.

[0030] The sealing block 25 is a cuboid and is located on the left side of the bottom blade 12. Its main function is to effectively prevent hair from entering the interior of the outer casing 1 during surgical hair removal, thus preventing the situation from becoming difficult to clean.

[0031] There are two fixed shafts 7, both of which are located at the bottom of the top cover 15. There are also two connecting sleeves 8, which are respectively fitted onto the outside of the fixed shafts 7.

[0032] There are two connecting rods 9. The main function of the two connecting sleeves 8 is that after the hair is cut, the two connecting sleeves 8 can be directly removed from the outside of the fixed shaft 7. Since the two connecting sleeves 8 are fixedly connected to the two connecting rods 9, the two connecting rods 9 can drive the bottom blade 12 to be directly disassembled, which makes it easy to replace the bottom blade 12 and also facilitates the disinfection of the bottom blade 12.

[0033] There are two push-pull plates 11, which are located on the front and rear sides of the eccentric shaft 6 respectively, and both push-pull plates 11 are cuboids.

[0034] The main function of the two push-pull plates 11 is to contact the eccentric shaft 6. When the eccentric shaft 6 rotates around the output shaft 4, it squeezes the two push-pull plates 11, thereby facilitating the displacement of the bottom blade 12 and achieving a shearing effect.

[0035] There are two slide grooves 13, which are located on the front and rear sides of the outer shell 1 respectively. There are two sliders 14, which are slidably connected to the two slide grooves 13 respectively.

[0036] The top cover 15 is installed and disassembled by sliding two sliders 14 and two grooves 13, which makes the overall installation and disassembly of the device convenient.

[0037] There are two of each of the following: insert rod 20, spring 21, and limiting ring 22. The two insert rods 20, springs 21, and limiting rings 22 are located on the front and rear sides of the outer shell 1, respectively. The diameter of the two limiting rings 22 is greater than the diameter of the spring 21. There are two fixing plates 18. The two fixing plates 18 are located on the right side of the two limiting rings 22.

[0038] The two limiting rings 22 are limited by the two fixing plates 18. When the two insert rods 20 pass through the inside of the two fixing plates 18, the two insert rods 20 are just locked with the insertion hole 17, thereby achieving the effect of easy fixation.

[0039] Working principle and usage process of this utility model:

[0040] First, a connecting plate 2 is fixedly installed inside the outer casing 1. A motor 3 is fixedly installed at the bottom of the connecting plate 2. An output shaft 4 is fixedly installed at the output end of the motor 3. A connecting plate 5 is fixedly installed above the output shaft 4. An eccentric shaft 6 is fixedly installed above the connecting plate 5. When the motor 3 is started, it drives the connecting plate 5 to rotate through the output shaft 4. Since the eccentric shaft 6 is fixedly connected to the connecting plate 5, the eccentric shaft 6 rotates with the connecting plate 5. At the same time, since the eccentric shaft 6 is located above the connecting plate 5 but is not coaxial, the eccentric shaft 6 has a certain eccentric effect. At this time, since the eccentric shaft 6 is in contact with the push-pull plate 11, when the eccentric shaft 6 rotates, it will drive the push-pull plate 11 to move. At the same time, the push-pull plate 11 drives the bottom blade 12 to move through the fixed connection between the connecting shaft 10 and the connecting rod 9, thereby achieving the left and right movement of the bottom blade 12 to cooperate with the top blade 16 above to achieve the effect of shearing hair.

[0041] Secondly, since an insertion hole 17 is opened inside the slider 14, and fixing plates 18 and 19 are fixedly installed on both the front and rear sides of the outer shell 1, insertion rods 20 are inserted into the fixing plates 18 and 19, and springs 21 are sleeved on the outside of the insertion rods 20. Limiting rings 22 are fixedly installed on the outside of the insertion rods 20. At the same time, springs 21 are fixedly connected to fixing plates 19 and limiting rings 22, and insertion rods 20 are inserted into the insertion hole 17. When the slider 14 is inserted into the outer shell 1 through the sliding action with the slide groove 13, the insertion rod 20 is pulled to the left so that the rightmost side of the insertion rod 20 is located on the left side of the insertion hole 17. When the slider 14 is installed to the bottom of the slide groove 13, the insertion rod 20 is released. At this time, the spring 21 provides elastic force to drive the limiting ring 22 to drive the insertion rod 20 into the insertion hole 17, so that the insertion hole 17 drives the slider 14 to be limited, thereby achieving the effect of fixing the top cover 15.

[0042] Finally, by pulling the insertion rod 20 to the left, the insertion rod 20 is disengaged from the insertion hole 17, making the connecting plate 5 easy to disassemble. At the same time, since the connecting sleeve 8 is fitted inside the fixed shaft 7, after the trimming is completed, the connecting sleeve 8 can be directly removed from the outside of the fixed shaft 7. Since the connecting sleeve 8 and the connecting rod 9 are fixedly connected, the connecting rod 9 can drive the bottom blade 12 to be directly disassembled, which facilitates the replacement of the bottom blade 12 and also facilitates the disinfection of the bottom blade 12.
