[0001] The utility model relates to the technical field of electric wrenches, in particular to a handheld small electric wrench. Background Art

[0002] As a modern tool, the development of electric wrenches has a profound technical background and is driven by market demand. Before the Industrial Revolution, people mainly relied on manual tools to tighten and remove bolts, which was not only inefficient but also extremely labor-intensive. With the development of power technology and the invention of motors, the foundation was laid for the emergence of electric tools. With the rapid development of the manufacturing industry, the requirements for production efficiency and quality are constantly improving. Electric wrenches have gradually become an indispensable tool in industrial production and maintenance due to their high efficiency, convenience, and precision.

[0003] Existing handheld trigger machines, due to their handheld design, mainly rely on fans for air cooling, with limited air volume and a relatively compact internal space, which is not conducive to rapid heat dissipation. This may lead to heat accumulation during long-term high-load operation, affecting equipment performance and service life. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a small handheld electric panel machine to solve the problem of low heat dissipation efficiency.

[0005] Based on the above-mentioned purpose, the utility model provides a handheld small electric machine, comprising: a coolant storage box, a hook fixedly installed on one side of the coolant storage box, a battery fixedly installed on the bottom end of the coolant storage box, the battery electrically connected to a drive pump fixedly installed inside the coolant storage box, a water outlet connecting pipe fixedly connected to the drive pump, the other end of the water outlet connecting pipe fixedly connected to the water inlet of the water valve connecting head, the water valve connecting head fixedly connected to a coolant circulation pipe at one end away from the water outlet connecting pipe, the other end of the coolant circulation pipe fixedly connected to the water outlet of the water valve connecting head, and connected to the water inlet connecting pipe, the other end of the water inlet connecting pipe fixedly connected to the coolant storage box.

[0006] As an optional embodiment, the coolant circulation pipe is fixedly installed inside the electric wrench body, and a stator core is provided inside the coolant circulation pipe and is fixedly installed on the electric wrench body.

[0024] In this way, the coolant storage box 1 is hung on the user's waist through the hook 101, and the coolant storage box 1 is connected to the electric wrench body 3 through the water inlet connecting pipe 2, which is convenient for access at any time. At the same time, when both hands are needed for operation, both hands are freed, which saves time and improves work efficiency. At the same time, it relieves the muscle tension and fatigue of the hands caused by holding tools for a long time. Coolant is added to the coolant storage box 1, and the drive pump 102 is started to let the coolant enter the coolant circulation pipe 202 through the water outlet connecting pipe 203, and then enters the coolant storage box 1 through the water inlet connecting pipe 2 for circulation, so as to bring out the heat generated inside the electric wrench body 3 due to long-term work, and protect components from damage due to overheating, thereby extending the service life of the electric wrench and maintaining the stable performance of the electric wrench. High temperature will cause problems such as motor power reduction and unstable torque output. The circulating cooling of the coolant can enable the electric wrench to always maintain good performance during work, thereby ensuring the quality and precision of the tightening work.

[0025] As an optional implementation, Figure 1-Figure 4As shown, the coolant circulation pipe 202 is fixedly installed inside the electric wrench body 3, and a stator core 301 is provided inside the coolant circulation pipe 202 and is fixedly installed on the electric wrench body 3; a rotor 302 is provided inside the stator core 301, and the rotor 302 is rotatably connected to the electric wrench body 3, and a fan blade 303 is fixedly installed on one side of the rotor 302, and the fan blade 303 is fixedly connected to the first bearing 305 at one end away from the rotor 302; the first bearing 305 is fixedly connected to the fixed bracket 304, and the first bearing 305 is fixedly connected to the helical gear rod 311 at one end away from the fan blade 303, and the helical gear rod 311 is fixedly connected to the fixed bracket 304. 1 is meshedly connected with a bevel gear 307; the bevel gear 307 is fixedly mounted on a rotating shaft connecting rod 306, one end of which is rotatably connected to a fixed bracket 304 and is located above a first bearing 305; the other side of the rotating shaft connecting rod 306 is fixedly connected to a second bearing 308, which is fixedly mounted on the electric wrench body 3; a clamping adjustment head 309 is fixedly mounted on the side of the second bearing 308 away from the bevel gear 307, and a clamping head 310 is fixedly mounted on the side of the clamping adjustment head 309 away from the second bearing 308; the lower end of the electric wrench body 3 is fixedly connected to the electric trigger handle 4.

A large amount of heat is generated under the frequent rotation of the rotor 302. The fan blade 303 can accelerate the flow of surrounding air, promote heat exchange with external air, and thus reduce the temperature of the equipment more quickly. The coolant storage box 1 is hung on the user's waist through the hook 101.

High temperature will cause problems such as motor power reduction and unstable torque output.
