DETAILED DESCRIPTION
[0015] In order to further understand the content of the present application, the present application will be described in detail below with reference to the drawings. EMBODIMENT
[0016] The embodiment provides a threaded hose locking structure of a laser beauty hand tool, as shown in the figure. Figs. 1-3 The threaded hose locking structure of the present application can effectively prevent the threaded hose from moving during work, and improve the working stability and reliability of the threaded hose 9.
[0017] Optionally, the holding part 2 in the embodiment is composed of two symmetrical semicircular housings 21, the tail end 10 of the connecting part 5 is further provided with external threads 11 at a preset distance, and the external threads 11 are further provided with end caps 12.
[0018] Optionally, the connecting part 5 in the embodiment is further provided with a circular limiting protrusion 13, the support pipe 8 is provided with a circular limiting groove 14, and the limiting protrusion 13 and the limiting groove 14 are matched. The limiting protrusion 13 and the limiting groove 14 are matched to limit the axial movement of the threaded hose 9.
[0019] Optionally, the connecting part 5 in the embodiment is further provided with internal threads 15, the internal threads 15 extend from the tail end 10 of the connecting part 5 to the limiting protrusion 13, and the threaded hose 9 and the internal threads 15 are matched, so that the threaded hose 9 is not easy to fall off.
[0020] The threaded hose locking structure provided by the embodiment is also convenient to install. First, the threaded hose 9 is sleeved on the support pipe 8 through the end cap 12 and the rubber ring 16, and then placed in the holding part 2. The two symmetrical semicircular housings 21 are assembled together, and finally the rubber ring 4 is sleeved and the end cap 12 is tightened. At this time, the threaded hose 9 can be reliably locked.
[0021] When the threaded hose 9 needs to be disassembled, the threaded hose 9 can be easily taken out by reversing the above steps. The threaded hose 9 locking structure of the utility model can effectively prevent the threaded hose 9 from moving during work, and improve the work stability and reliability of the threaded hose 9.
[0022] Optionally, the threaded hose locking structure provided by the embodiment is provided with a button 3 on the holding part 2 for controlling the laser energy output of the hand tool 1; the holding part 2 is further provided with a touch piece 4 for sensing human body contact, a control module 6 with sensing capacitance is arranged below the touch piece 4, and the control module 6 is further provided with a circuit for cutting off the laser energy supply.
[0023] The touch piece 4 in the embodiment is equivalent to the insurance of the button 3. Only when the touch piece 4 detects human skin, the operation of the button 3 can be performed.

[0025] When in use, when the user operates the hand tool 1, first hold the holding part 2, and place the index finger on the button 3. At this time, the middle finger will contact the touch piece 4.
[0026] When the user aims the treatment head at the skin and presses the button 3, if the touch piece 4 detects the skin (middle finger), the system judges that the operation is normal, and allows the treatment head to work.
[0027] If the touch piece 4 is not sensed to the skin during use, it is judged as a false touch risk, at which time the button 3 action fails and the treatment head stops working.
[0028] The system continuously monitors the hand tool 1 state and the user's operation intention. If normal operation is not detected within a certain time, the hand tool 1 power is automatically turned off to ensure safety.
[0029] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications.
