[0010] Preferably, an adjusting rod and a thrust surface that cooperate with each other are provided between the self-locking ring and the control button, and a limiting block that matches the adjusting rod is also provided on the control button.

[0011] Preferably, the control button is provided with a mounting groove, and a return spring is provided in the mounting groove; the electrical socket is provided with a limit column, and one end of the return spring is sleeved on the limit column.

[0012] Preferably, a circumferential limiting groove and a limiting plate that cooperate with each other are provided between the self-locking ring and the socket.

[0013] Preferably, mutually matching plug-in marks are provided between the plug and the handle.

[0014] Preferably, an axial limiting groove adapted to the end surface of the electric heating hairdressing head is provided at the inlet end of the connecting hole.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention comprises a handle and an electric hairdressing head, which are electrically connected to each other through a conductive pin and an electric socket that cooperate with each other; at the same time, a self-locking ring is rotatably arranged in the connection hole of the handle, and an adjustment groove is arranged on the inner surface of the self-locking ring, and a corresponding push block is arranged on the outer surface of the plug, and a push surface is obliquely arranged between the inlet end of the adjustment groove and the push block; at the same time, a locking groove is arranged at the rear end of the adjustment groove along the circumferential direction of the self-locking groove; the self-locking ring realizes the reset and locking of the plug through an elastic reset device between the self-locking ring and the handle; and a control button is also arranged on the handle;

[0017] When the present invention is used, the conductive needle of the electric heating hairdressing head is inserted into the corresponding electric socket. During this process, the push block will enter the adjusting groove, and the top pushing surface between the adjusting groove and the push block will fit together. Since the top pushing surface is arranged inclined, the thrust of the push block will be decomposed into two components along the circumferential direction and the axial direction of the self-locking ring, wherein the component in the circumferential direction will push the self-locking ring to rotate, and at the same time, the self-locking ring compresses the elastic reset device; since the locking groove is arranged along the circumference of the self-locking ring, when the push block moves to the intersection of the adjusting groove and the locking groove, the push block is out of contact with the adjusting groove, and at this time, the self-locking ring is reversed and reset under the action of the elastic reset device, and the push block enters the locking groove to complete the locking of the electric heating hairdressing head;

[0018] Compared with the integral structure commonly used in the prior art, the present invention realizes the function of simultaneously adapting a variety of electric heating hairdressing heads such as straight hair and curly hair on one handle, which not only expands the use function of the hairdressing device, but also reduces the purchase cost of consumers; and the electric heating hairdressing head and the handle are separated from each other. When any device is damaged, it can be used again by replacing the damaged parts without scrapping the whole device, so the use cycle of the device is extended, while reducing resource waste and consumer use costs;

[0019] At the same time, the present invention converts the thrust parallel to the axis of the electric heating hairdressing head during the plugging process into an extrusion force in the circumferential direction through an ingenious structural design, thereby pushing the self-locking ring to rotate and give way, and then resetting and locking through the resetting device; during use, the electric heating hairdressing head and the handle can be quickly and stably connected without applying additional force, and the electric heating hairdressing head can be replaced by pressing the control button; compared with the traditional buckle-type connection and fixing method, the electric heating hairdressing head can be quickly replaced without pressing the corresponding elastic buckle, which is convenient and labor-saving;

[0020] Finally, the locking groove of the present invention has a sufficiently large contact area with the push block, so it can effectively ensure the stability of the connection. At the same time, compared with traditional elastic buckles, the stability of each structure is stronger, which can effectively improve the service life of the equipment.

[0021] 2. The present invention is provided with 2-4 sets of pushing devices and the same number of locking devices between the plug and the self-locking ring. On the one hand, it can increase the circumferential separation, push the self-locking ring to rotate, and use it more labor-saving; at the same time, the evenly arranged plugs can ensure that the self-locking ring is subjected to uniform force, ensure the stability of its structure and installation position, and avoid unnecessary wear caused by friction between the self-locking ring and the handle.

[0022] 3. The elastic reset device of the present invention includes a reset spring and an adjustment block, and a mounting hole for placing the reset spring is also provided on the handle. This design simplifies the structure of the elastic reset device to the greatest extent while meeting the basic use functions, thereby improving the reliability and stability of the device; at the same time, it avoids the elastic reset device from occupying a large internal space, so that the handle is matched with the elastic reset device, thereby reducing the volume of the entire device, making the size of the device adaptable to the user's grip arc, and improving the user's comfort.

[0023] 4. The present invention has two sets of centrally symmetrical return spring devices on the left and right sides of the self-locking ring. The centrally symmetrical structure ensures that the springs and adjustment blocks on the left and right sides are exactly opposite, so that when the self-locking ring rotates, the adjustment blocks on both sides can squeeze the return springs to ensure that the self-locking ring is evenly stressed and avoid outward tilting due to uneven stress, which not only affects the coordination between the components, but also generates unnecessary friction and wear, affecting the processability and service life of the equipment.

[0024] 5. A thrust surface and an adjusting rod that cooperate with each other are arranged between the control button and the self-locking ring of the present invention. A limit block that matches the adjusting rod is also arranged on the control button, and a reset spring is also arranged between the control button and the electrical socket. When the lock needs to be released, the control button is pressed. During the downward movement of the control button, the adjusting rod is pressed downward by the thrust surface, thereby driving the self-locking ring to rotate, so that the push block returns to the adjusting groove. At this time, the electric hairdressing head can be pulled out by pressing the control button;

[0025] This design makes full use of the positional relationship between the control button and the self-locking ring, simplifies the structure of the device to the greatest extent while realizing the unlocking function. It not only improves the reliability and stability of the device, but also greatly simplifies the replacement of the hairdressing head, making it more convenient to use.

[0026] The setting of the reset spring can not only realize the rapid reset of the control button, but also its supporting effect on the control button can ensure the stability of the control button and prevent it from loosening.

[0027] 6. The present invention also provides a circumferential limit groove and a limit plate that cooperate with each other between the self-locking ring and the socket. The rotation range of the self-locking ring is limited by the cooperation of the above two components. At the same time, the self-locking ring can be braked in time during the reverse reset process to ensure the accuracy and reliability of locking; at the same time, the impact force on the push block and other components is shared.

[0028] 7. The present invention provides a plug-in mark between the plug and the handle, through which the user can complete the installation accurately and quickly to ensure the accuracy of the connection.

[0029] 8. The present invention also provides an axial limit groove on the connecting hole to limit the insertion depth of the electric heating hairdressing head and ensure the matching accuracy between the push block and the locking groove; at the same time, the force exerted on the hairdressing head is just opposite to the force exerted on the hairdressing head by the locking groove, thereby improving the stability of the connection of the hairdressing head.

[0049] Implementation Method 2

[0050] This embodiment is a preferred embodiment of the present invention, which discloses a multifunctional electric heating hairdressing device, the specific structure is as follows: Figure 3 , 9 As shown in FIG. 11 , the handle 1 and the electric hairdressing head 2 are provided with a plug 4 and a connecting hole 3 that cooperate with each other, a plurality of push blocks 81 are evenly arranged on the outer circumference of the plug 4, a self-locking ring 7 is rotatably arranged in the connecting hole 3, a plurality of adjusting grooves 82 corresponding to the push blocks 81 are arranged on the inner wall of the self-locking ring 7, and an annular axial limiting groove 31 is arranged at the inlet end of the adjusting groove 82, and the axial limiting groove 31 limits the maximum insertion depth of the electric hairdressing head 2 by cooperating with the end face of the plug 4; at the same time, a plug-in mark 12 is provided on both the handle 1 and the plug 4, so that the user can quickly align the handle 1 and the electric hairdressing head 2;

[0051] Furthermore, a conductive pin 6 is fixedly provided on the plug 4, an electrical socket 5 is fixedly provided in the handle 1, and the plug-in end of the electrical socket 5 is inserted into the self-locking ring 7; a circumferential limit groove 72 is provided at the bottom of the self-locking ring 7, and a limit plate 52 is provided at the bottom of the electrical socket 5, and the limit plate 52 is inserted into the circumferential limit groove 72.

[0052] The practical method of the present invention comprises the following steps:

[0053] S1. After aligning the plug-in marks on the handle and the electric hairdressing head, insert the electric hairdressing head into the connection hole and ensure that the conductive pin is inserted into the corresponding electrical socket plug-in hole;

[0054] S2. Push the electric heating hairdressing head toward one side of the handle to insert it. After the self-locking ring is rotated to unlock and then reversed to lock, the handle and the electric heating hairdressing head are fixedly connected.

[0055] The working principle of the present invention is as follows: when the electric heating hairdressing head is inserted into the connecting hole, the push block contacts the top push surface of the adjusting groove. Since the top push surface is inclined, the push block applies a thrust to the adjusting groove when inserted axially, and the thrust can be decomposed into two components along the axial direction and the circumferential direction of the self-locking ring, wherein the component in the circumferential direction will push the self-locking ring to rotate, and the reset spring will be squeezed during the rotation of the self-locking ring; when the push block continues to penetrate into the adjusting groove, the push block applies a force opposite to the reset spring to the side wall of the adjusting groove, thereby ensuring the stability of the self-locking ring; and when the push block is completely in the connecting portion between the adjusting groove and the locking groove, the push block and the side wall of the adjusting groove will be out of contact, and the force of the push block disappears. At this time, under the action of the reset spring, the self-locking ring rotates in the opposite direction and inserts the push block into the locking groove, the inner wall of the locking groove abuts against the rear end face of the push block, and at the same time, the plug end face of the electric heating hairdressing head abuts against the axial limit groove, thereby completing the fixation of the push block, and then completing the fixation of the electric heating hairdressing head;

[0056] When the electric heating hairdressing head needs to be replaced, the control button is pressed downwards. During the sliding process of the control button, the thrust surface pushes the self-locking ring to rotate through the adjustment rod and squeezes the reset spring at the same time; the push block returns to the adjustment slot again to keep the control button stable, and the electric heating hairdressing head can be separated from the handle by pulling it outwards, and then the control button is released. Under the action of the two reset springs, the control button and the self-locking ring will reset themselves;

[0057] Compared with the prior art, the present invention can replace multiple different types of plugs on one handle, and meet the consumers' needs for straight hair and curly hair through a set of equipment, which expands the use function and reduces the purchase cost; at the same time, due to the split structure, when the equipment is damaged, the remaining equipment can be reused by replacing the damaged parts, which is not only conducive to the reuse of resources, but also reduces the use cost;

[0058] The present invention converts the thrust in the axial direction into the thrust in the circumferential direction through a clever structural design, thereby realizing self-locking of the electric heating plug. It is not only convenient to operate and simple to use, but also simplifies the internal structure of the entire equipment and improves the stability and reliability of the equipment.
