[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0023] See also Figure 1-Figure 4 As shown, a child's head fixing device includes a head fixer body 1, a fixed head assembly 2 is arranged above the head fixer body 1, the fixed head assembly 2 is used to fix the child's head, the fixed head assembly 2 includes a support rod 201 fixedly connected to the outer wall of the head fixer body 1, the outer wall of the support rod 201 is rotatably connected to two arc-shaped connecting plates 202, the outer wall of the arc-shaped connecting plate 202 is fixedly installed with an arc-shaped clamping block 203, the arc-shaped clamping block 203 is located on the side of the arc-shaped connecting plate 202 away from the support rod 201, the arc-shaped clamping block 203 is plugged with a plurality of pressure rods 204, one end of the pressure rod 204 extending to the inside of the arc-shaped clamping block 203 is fixedly connected with a tension spring 205, and the end of the tension spring 205 away from the pressure rod 204 is rotatably connected to the inner wall of the arc-shaped clamping block 203.

[0024] Place the child's head between the two arc-shaped clamping blocks 203, and then move the two arc-shaped clamping blocks 203 towards the child's head at the same time. When the arc-shaped clamping blocks 203 move, the arc-shaped connecting plate 202 will rotate along the outer wall of the support rod 201;

[0025] When the pressure rod 204 hits the child's head, it will move toward the inside of the arc-shaped clamping block 203 and squeeze the tension spring 205 until the pressure rod 204 hits multiple parts and multiple areas of the head. The multiple pressure rods 204 will squeeze the tension spring 205 to different degrees according to their positions close to the head, so that the multiple pressure rods 204 can all contact the head, increasing the contact area between the multiple pressure rods 204 and the head, so that the pressure rods 204 can fit the scalp better.

[0026] See also Figure 1-Figure 2 An elastic ball 3 is fixedly installed on one end of the pressure rod 204 away from the arc-shaped clamping block 203. The pressure rod 204 and the elastic ball 3 are both located on the side corresponding to the two arc-shaped clamping blocks 203, and multiple elastic balls 3 correspond to each other.

[0027] The elastic ball 3 can relieve the pressure of the pressure rod 204 on the scalp. Since the pressure rod 204 is relatively hard, if the pressure rod 204 directly contacts the scalp, the scalp will feel pain and discomfort. The elastic ball 3 contacts the scalp instead of the pressure rod 204. Since the elastic ball 3 is softer, it can reduce the discomfort on the head and prevent children from resisting wearing it due to discomfort.

[0028] See also Figure 2 A plurality of insertion holes 4 are provided on the corresponding sides of the two arc-shaped clamping blocks 203 , and the pressure rod 204 is located inside the insertion hole 4 and is slidably connected to the insertion hole 4 .

[0029] The insertion hole 4 provides space for the pressure rod 204 to enter and exit the arc clamping block 203, so that the pressure rod 204 can extend into the arc clamping block 203 after squeezing the head, so that the pressure rod 204 can adjust its own length and fix the head conveniently.

[0030] See also Figure 3-Figure 4 Two gears 10 are fixedly installed on the outer wall of the support rod 201, a return spring 5 is fixedly installed on the outer wall of the arc-shaped connecting plate 202, a sliding rod 6 is fixedly installed on the end of the return spring 5 away from the arc-shaped connecting plate 202, an L-shaped fixing rod 7 is fixedly installed on the end of the sliding rod 6 away from the return spring 5, and the end of the L-shaped fixing rod 7 away from the sliding rod 6 is located between multiple teeth of the support rod 201.

[0031] Before adjusting the position of the arc-shaped clamping block 203, it is necessary to pull the L-shaped fixing rod 7 away from the gear 10, and at this time, the slide rod 6 will also stretch the reset spring 5. When the arc-shaped clamping block 203 and the pressure rod 204 move to a certain position and the head has been fixed, the arc-shaped connecting plate 202 will stay at a certain position, and the side of the arc-shaped connecting plate 202 away from the arc-shaped clamping block 203 will also correspond to a certain area on the support rod 201. Then, the L-shaped fixing rod 7 is released, and the reset spring 5 will pull the slide rod 6 and the L-shaped fixing rod 7 back to their original positions.

[0032] After the L-shaped fixing rod 7 returns to its original position, one end of the L-shaped fixing rod 7 will be stuck in a tooth gap of the gear 10. At this time, the arc-shaped connecting plate 202 can no longer rotate along the outer wall of the support rod 201, and the arc-shaped clamping block 203 cannot be moved, thereby achieving the fixation of the position of the arc-shaped clamping block 203 to prevent the arc-shaped clamping block 203 from loosening after fixing the head.

[0033] See also Figure 3 A sleeve 8 is fixedly mounted on the outer wall of the arc-shaped connecting plate 202 , the return spring 5 and the slide rod 6 are both located inside the sleeve 8 , and the outer wall of the slide rod 6 is slidably connected to the inner wall of the sleeve 8 .

[0034] If the slide bar 6 is connected to the arc-shaped connecting plate 202 only by the return spring 5, the slide bar 6 will become unstable, and the slide bar 6 itself may shake and deviate. The sleeve 8 limits the moving direction of the slide bar 6, so that the slide bar 6 can only move horizontally. In this way, the slide bar 6 will be more stable when moving, and will not easily deviate or tilt, and the L-shaped fixing rod 7 will also be more stable.

[0035] See also Figure 3 A pull ring 9 is fixedly installed on the outer wall of the L-shaped fixing rod 7, and the pull ring 9 is located on a side of the L-shaped fixing rod 7 away from the sliding rod 6.

[0036] The pull ring 9 provides a pulling force for the L-shaped fixing rod 7 , so that when the user needs to move the L-shaped fixing rod 7 away from the gear 10 , the user only needs to pull the pull ring 9 to drive the L-shaped fixing rod 7 to move, making the L-shaped fixing rod 7 easier to operate.

[0037] Working principle:

[0038] Place the child's head between the two arc-shaped clamping blocks 203, and then move the two arc-shaped clamping blocks 203 towards the child's head at the same time. When the arc-shaped clamping blocks 203 move, the arc-shaped connecting plate 202 will rotate along the outer wall of the support rod 201;

[0039] When the pressure rod 204 hits the child's head, it will move toward the inside of the arc-shaped clamping block 203 and squeeze the tension spring 205 until the pressure rod 204 hits multiple parts and multiple areas of the head. The multiple pressure rods 204 will squeeze the tension spring 205 to different degrees according to their positions close to the head, so that the multiple pressure rods 204 can all contact the head, increasing the contact area between the multiple pressure rods 204 and the head, so that the pressure rods 204 can fit the scalp better.

[0040] Before adjusting the position of the arc-shaped clamping block 203, it is necessary to pull the L-shaped fixing rod 7 away from the gear 10, and at this time, the slide rod 6 will also stretch the reset spring 5. When the arc-shaped clamping block 203 and the pressure rod 204 move to a certain position and the head has been fixed, the arc-shaped connecting plate 202 will stay at a certain position, and the side of the arc-shaped connecting plate 202 away from the arc-shaped clamping block 203 will also correspond to a certain area on the support rod 201. Then, the L-shaped fixing rod 7 is released, and the reset spring 5 will pull the slide rod 6 and the L-shaped fixing rod 7 back to their original positions.

[0041] After the L-shaped fixing rod 7 returns to its original position, one end of the L-shaped fixing rod 7 will be stuck in a tooth gap of the gear 10. At this time, the arc-shaped connecting plate 202 can no longer rotate along the outer wall of the support rod 201, and the arc-shaped clamping block 203 cannot be moved, thereby achieving the fixation of the position of the arc-shaped clamping block 203 to prevent the arc-shaped clamping block 203 from loosening after fixing the head.
