[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] See Figure 1-7 An embodiment of this utility model provides a heating tweezer, including a shell 1, tweezers head 2, heating block 3 and temperature control sensor 4.

[0025] The outer casing 1 has an end 11 and two support arms 12. The end 11 is a block structure with a first side and a second side opposite to the first side. Both support arms 12 are rod-shaped structures with a first end and a second end. The first end of each support arm 12 is connected to the first side of the end 11. The two support arms 12 are arranged side by side. The outer casing 1 is formed by fastening two shells together along a direction perpendicular to the plane of the two support arms 12. The inner sides of the two support arms 12 can be supported by elastic telescopic members. The outer sides of each support arm 12 can have a pressing part.

[0026] The tweezers head 2 comprises two tweezers heads. Each tweezers head 2 has a conical structure. The larger ends of the two tweezers heads 2 are respectively mounted on the second ends of the two support arms 12. The two tweezers heads 2 are symmetrically arranged. Under the above conditions, the smaller ends of both tweezers heads 2 are inclined towards the midline between the two tweezers heads 2.

[0027] The heating block 3 comprises two components. Each heating block 3 is encapsulated within the larger end of one of the two tweezer tips 2. The connecting wires of the two heating blocks 3 extend through the two support arms 12 to the second side of the end 11 and connect to a power source. This arrangement allows the power source to supply power to the two heating blocks 3, and the two heating blocks 3 to heat the two tweezer tips 2 respectively.

[0028] Two temperature control sensors 4 are included. Each temperature control sensor 4 is encapsulated within the large end of one of the two forceps tips 2. The two temperature control sensors 4 are respectively attached to one of the two heating blocks 3. The connecting wires of the two temperature control sensors 4 extend through the support arm 12 to the second side of the end 11 and connect to an external structure. This external structure can be a temperature control structure, allowing the temperature sensors 4 to be used for temperature control. This configuration allows the heating forceps to directly integrate the heating blocks 3 and temperature control sensors 4 within the forceps tips 2, ensuring sufficient heating and precise temperature control. This maintains a constant temperature in the forceps tips 2, preventing wax from solidifying and adhering to tissues due to large temperature fluctuations. This effectively improves the efficiency of embedding work. Furthermore, the heated forceps are small, lightweight, ergonomically designed, and offer excellent grip. They also have a simple structure and low manufacturing cost.

[0029] In addition, the heated tweezers may also include a heat-insulating baffle. The heat-insulating baffle is fixed inside the two support arms 12. The heat-insulating baffle divides each support arm 12 into a tweezers head fixing section and an operating section, with the length of the tweezers head fixing section being shorter than the length of the operating section. An opening is provided on the heat-insulating baffle for the connecting wires of the heating block 3 and the temperature control sensor 4 to pass through. Under the above conditions, the larger end of the tweezers head 2 is secured within the tweezers head fixing section, and the connecting wires of the heating block 3 and the temperature control sensor 4 extend through the opening into the operating section, and then into the end 11. A heat dissipation hole is provided on the side of the operating section.

[0030] In some embodiments, the heated tweezers also include a battery socket 5, a battery 6, and a battery charging base 7.

[0031] The battery socket 5 is embedded in the second side of the end 11. The battery socket 5 is connected to the connecting wire of the heating block 3. The battery socket 5 can be an audio socket structure.

[0032] Battery 6 has a connector plug 61. Connector plug 61 is inserted into battery socket 5. Connector plug 61 can be an audio plug structure.

The above arrangement allows battery 6 to be directly inserted into battery socket 5. Battery 6 provides power, and heating block 3 integrated in tweezers head 2 heats up, transferring heat to tweezers head 2 for operation. Battery 6 has a power indicator light 62. When fully charged or charged (above 20% power), the indicator light is always on. If the indicator light starts flashing, it indicates that the power is below 20%, prompting replacement of battery 6. Replaced battery 6 is then charged for the next stage of use. Battery 6 has a battery casing 63, which is formed by two battery casing shells fastened together along the insertion and removal direction of battery 6. Multiple batteries 6 are included.

[0033] The battery charging base 7 has multiple battery charging sockets 71. Each battery charging socket 71 is for inserting a specific battery 6. The battery charging socket 71 can be an audio jack structure. The battery charging base 7 also has an electrical connection interface 72. The electrical connection interface 72 connects the power source to each battery charging socket 71. The electrical connection interface 72 can be a Type-C socket interface. The above configuration allows the battery charging base 7 to accommodate multiple batteries 6 for interchangeable use, ensuring continuous operation of the heated tweezers, improving embedding quality. The heated tweezers are wireless, requiring no connecting wires, making operation more flexible and convenient. The battery charging base 7 has a working indicator light 72, which illuminates when the device is in operation. The battery charging base 7 is formed by the battery charging base shell 73 and the battery charging base base plate 74 being snapped together. Optionally, the electrical connection interface 73 can be directly connected to a power source. Alternatively, the electrical connection interface 73 can be used to power the embedding machine 10 by inserting a connecting cable with a Type-C plug on one end and a USB plug on the other end into the USB socket of the embedding machine 10.

[0034] Under the above conditions, the working principle of the heated tweezers is as follows: the battery socket 5 is placed inside the outer shell 1, and then the heating block 3 and the temperature control sensor 4 are placed into the two metal tweezer heads 2 respectively. After sealing, they are installed into the outer shell 1 and the two outer shells 1 are fastened together. The battery 6 is placed inside the battery outer shell and the two battery outer shells are fastened together. Then the battery 6 is inserted into the battery socket 5. The indicator light of the battery 6 lights up, indicating that it is powered on. The heating block 3 starts to heat up and conducts heat to the tweezer heads 2. The tweezer heads 2 start to heat up, and the temperature control sensor 4 starts to control the temperature, so that it reaches the required temperature and maintains a constant temperature, thus working effectively and stably.

[0035] In addition, the heated tweezers may also include a battery retainer. The battery retainer covers the outside of the battery 6. The inner circumference of the open end of the battery retainer has threads, and the outer circumference of the second end of the end 11 has corresponding threads. The battery retainer is threadedly installed at the second end of the end 11. The inner side of the closed end of the battery retainer presses against the battery 6.

Power is supplied through the embedding machine 10, thereby heating the heating block 3 integrated in the tweezers head 2 and transferring the heat to the tweezers head 2 for operation.

[0038] Under the above conditions, the working principle of the heated tweezers is as follows: the electrical connection socket 8 is placed inside the outer shell 1, and then the heating block 3 and the temperature control sensor 4 are placed into the two metal tweezer heads 2 respectively. After sealing, they are installed into the outer shell 1 and the two outer shells 1 are fastened together. Then, the connecting wire 9 with the plug is inserted into the electrical connection socket 8. After power is turned on, the heating block 3 starts to heat up and conducts heat to the tweezer heads 2.
