[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 An electric screwdriver with temperature control alarm is shown, and the embodiment of the present application provides, including a body 1 and a screwdriver head 101 arranged at its end, a temperature control component arranged at the other end of the body 1, and a limit component arranged outside the screwdriver head 101. The temperature control component includes an isolation ring 2 arranged at the end of the body 1, a probe 201 arranged at the center of the isolation ring 2, and a vibration motor 202 arranged inside the isolation ring 2;

[0026] The limit assembly includes a sleeve 3 which is sleeved on the end of the body 1, the outer wall of the sleeve 3 includes a through groove parallel to the screwdriver bit 101, the inner wall of the sleeve 3 is provided with two parallel springs 301, and a spring 302 between the sleeve 3 and the body 1;

[0027] The isolation ring 2 is arranged at the end of the body 1, which extends the grippable area of ​​the outer side of the body 1, making it easier to hold. The probe 201 is arranged on the central axis of the body 1, and the temperature measurement position is accurate, so that the temperature inside the body 1 can be measured quickly and accurately. The isolation ring 2 acts as a barrier between the probe 201 and the user's hand, which is safer. When the temperature of the body 1 is too high, the vibration motor 202 generates high-frequency vibration to realize the alarm function.

[0028] The sleeve 3 is connected to the outer side of the step at the end of the body 1 to cover the screw head 101. The screw is put into the sleeve 3 through the external through slot. The sleeve 3 can slide relative to the screw head 101, so that the screw can be clamped on the screw head 101. The screw is clamped by the spring piece 301 to fix the screw tip, so that the screw is not easy to fall out of the sleeve 3. At the same time, the accuracy of the screw position is guaranteed, and the slippage of the screw tip during the tightening process is reduced;

[0029] When loosening the screw, the sleeve 3 retracts to a position close to the end of the body 1, and the screwdriver bit 101 continuously screws out the screw. After the screw is detached, the spring piece 301 has a fixing effect on it, so that the screw is not easy to fall off, and it is more convenient to use.

[0030] In this embodiment, Figure 2-Figure 4 As shown; a groove is provided on the side of the isolating ring 2 facing away from the body 1, and the vibration motor 202 is arranged on the inner wall of the groove on the back side of the isolating ring 2;

[0031] The vibration motor 202 is disposed inside the isolation ring 2 . The vibration motor 202 is shielded by the isolation ring 2 , which is safer and can reduce the impact of heat from the user's hands on it.

[0032] A sound-generating sheet 203 is fixedly connected to the wall surface of the groove on the back of the isolation ring 2, and the sound-generating sheet 203 is attached to the outer wall of the vibration motor 202;

[0033] The vibration generated by the vibration motor 202 when working is transmitted to the sound-generating plate 203, and the sound wave is generated by the vibration of the sound-generating plate 203, and the sound is used to prompt the user, thereby playing an alarm role.

[0034] The outer wall of the sleeve 3 is provided with a T-shaped through groove, one side opening of which is provided on the end face of the sleeve 3, the end of the sleeve 3 is slidably connected with a guide column 303, and the other end of the guide column 303 is fixedly connected to the end face of the body 1;

[0035] The sleeve 3 is limited by the guide column 303 to maintain an accurate position, thereby preventing the deviation of the sleeve 3 from affecting the rotation of the screwdriver bit 101;

[0036] Since the inner cavity of the sleeve 3 is mainly used to accommodate the screw, the inner cavity of the sleeve 3 has the same diameter as the end face of the screw, and the sleeve 3 can achieve a good positioning effect on the screw. However, it is not convenient to align the screw in the sleeve 3 at this time, and the assembly work is more complicated.

[0037] This situation can be avoided by using the through slots provided in the side wall of the sleeve 3 to assemble the screws. The through slots are adapted to the shape of the screws and are set in a "T" shape. The screws can be installed in the sleeve 3 parallel to the sleeve 3, which facilitates the assembly work.

[0038] The spring pieces 301 are arranged on both sides of the through slot of the sleeve 3;

[0039] When the screw enters the interior of the sleeve 3 from the side through slot of the sleeve 3, it is clamped by the two spring pieces 301, so as to position the screw and ensure that the screw and the screw bit 101 are on the same central axis.

[0040] The spring piece 301 includes an inclined portion 304 facing the center of the end surface of the sleeve 3;

[0041] The inclined portion 304 has a good limiting effect on the threaded portion of the screw. During the rotation of the screw, the screw continues to penetrate into the fastening surface. The inclined surface of the inclined portion 304 has a guiding function and can slide along the outer peripheral surface of the screw to maintain the fixing effect on the screw.

[0042] The distance between the two inclined portions 304 is the same as the size of the end opening of the sleeve 3;

[0043] The edge of the inclined portion 304 is disposed below the through slot to avoid obstruction of the screws during assembly, thereby ensuring work efficiency.
