[0029] The electrostatic protection is extremely important during the use of the hand tool. The external structure of the hand tool is the first line of defense for the electrostatic protection of the hand tool, and the internal part of the hand tool is provided with a radio frequency wire connected with a needle (i.e. an electrode) of the head of the hand tool to conduct radio frequency energy. When the electrostatic test is performed, the needle part of the hand tool is an electrostatic test point, and thus the electrostatic can enter the internal part of the hand tool through the channel of the needle and the radio frequency wire to cause harm to other cables (such as signal lines) in the internal part, and even damage the product.

[0030] In view of this, in view of the problem that the electrostatic in the above-mentioned existing hand tool enters the internal part of the hand tool through the needle and the radio frequency wire to cause harm to the electronic elements in the internal part, and even damage the product, the utility model provides a hand tool 100 and a therapeutic instrument, which aims at improving the above-mentioned problem.

[0031] The specific structure of the hand tool 100 and the therapeutic instrument of the utility model will be described below:

[0032] Please refer to Figures 1 to 6 The utility model provides a hand tool 100, the hand tool 100 includes: the shell 10 is equipped with installation cavity 11, and the electronic element 20 is arranged in the installation cavity 11, and the electronic element 20 includes radio frequency wire 21 and control line 22, wherein the installation cavity 11 is formed with the radio frequency channel 111 and control channel 112 that are arranged at intervals, the radio frequency wire 21 is arranged in the radio frequency channel 111, and the control line 22 is arranged in the control channel 112.

[0033] Specifically, the hand tool 100 includes the shell 10 and the electronic element 20, the shell 10 is used for protecting and installing the internal electronic element 20, the electronic element 20 includes the radio frequency wire 21 and the control line 22, the radio frequency wire 21 is used for conducting radio frequency energy, and the control line 22 includes various signal lines and control lead lines.

[0034] The radio frequency wire 21 is installed in the radio frequency channel 111 as strong electricity, the control line 22 is installed in the control channel 112 as weak electricity, the radio frequency channel 111 and the control channel 112 are arranged at intervals, so that the radio frequency wire 21 and the control line 22 are also arranged at intervals, the strong electricity and the weak electricity are separated and wired, and the space is installed in a staggered manner, even if the electrostatic enters the internal part of the hand tool 100 through the radio frequency wire 21, it is also difficult to cause harm to the control line 22, and the product is prevented from being damaged.

[0035] The mode that the radio frequency channel 111 and the control channel 112 are arranged at intervals in the installation cavity 11 can be arranged as the radio frequency wire 21 and the control line 22 are arranged on two sides in the installation cavity 11, and the natural space distance is used to realize the separation, a partition can be arranged in the shell 10, and a support frame can also be arranged in the shell 10.

[0036] By separating the radio frequency wire 21 and the control wire 22, even if static electricity enters the inside of the hand tool 100, it will not directly impact the control wire 22 in the control channel 112, protecting the control wire 22 which is sensitive to static electricity from being damaged or failing due to static discharge.

[0037] In addition, the radio frequency wire 21 transmits high-frequency energy, which can cause electromagnetic interference, thereby interfering with the signals transmitted on other cables. By separating the two, the impact of electromagnetic interference can be significantly reduced, ensuring that the control wire 22 can stably transmit data, instructions, and other information, improving the reliability and accuracy of the equipment. By preventing static damage and reducing electromagnetic interference, the durability and longevity of the hand tool 100 are improved.

[0038] The utility model technical scheme separates the radio frequency wire 21 and the control wire 22 by setting the radio frequency channel 111 and the control channel 112 in the shell 10, and installs the radio frequency wire 21 and the control wire 22 in the radio frequency channel 111 and the control channel 112 respectively, which are installed in a separate wiring mode. Even if static electricity enters the inside of the hand tool 100 through the radio frequency wire 21, it will not directly affect the control wire 22 in the control channel 112, protecting the control wire 22 from being damaged or failing due to static discharge, and preventing damage to the product.

[0040] In detail, the detachable design of the upper shell 12 and the lower shell 13 makes it easier to install and maintain the internal components of the hand tool 100. The bracket 14 can be a support plate or a cylinder structure. Figure 1 By arranging the bracket 14 inside, the radio frequency channel 111 and the control channel 112 are arranged in the bracket 14, which facilitates wiring and better connects the radio frequency wire 21 and the control wire 22, ensuring that the cables have fixed positions and avoiding chaotic wiring. At the same time, the bracket 14 also enhances the firmness and durability of the shell 10. Furthermore, the cables are installed on the bracket 14 and then placed in the lower shell 13, and finally the upper shell 12 is closed. Since the upper shell 12 does not have a connection with the wiring, it avoids the problem of pressing the wiring caused by blind installation of the wiring, which is not prone to pressing the wiring and facilitates installation.

[0043] Notably, by arranging the two first side plates 1412 on the first bottom plate 1411 and arranging the first wire pressing plate 142 between the first bottom plate 1411 and the two first side plates 1412, two independent channels along the height direction, i.e., the radio frequency channel 111 and the control channel 112, are formed on the first baffle piece 141. Figure 3 The radio frequency wire 21 passes between the first bottom plate 1411 and the first wire pressing plate 142, and the control wire 22 passes above the first wire pressing plate 142, the first wire pressing plate 142 physically separates the two channels, this design can make full use of the limited space, effectively isolate the radio frequency wire 21 and the control wire 22, and help reduce electromagnetic interference between them, and ensure the clarity of the signal and the stability of the system.

[0047] In detail, the second wire pressing plate 144 is in the shape of a hat with one side open, and the size is greater than the interval of the oppositely arranged second side plates 1432, the additional physical barrier is increased by the second baffle piece 143 and the second wire pressing plate 144, the structural stability is enhanced, a more independent installation environment is provided for the radio frequency wire 21 and the control wire 22, the second wire pressing plate 144 is covered outside the second bottom plate 1431 and the two second side plates 1432, and a closed radio frequency channel 111 and control channel 112 are formed. The two isolation channels formed by the second baffle piece 143 and the second wire pressing plate 144 can effectively isolate the radio frequency wire 21 and the control wire 22, and reduce the electromagnetic interference and electrostatic propagation path between each other. In addition, the two sides of the second baffle piece 143 are provided with clamping blocks 1433 to better fix the radio frequency wire 21.

[0048] As shown in the figure, Figures 2 to 4 The first baffle piece 141 and the second baffle piece 143 are made of insulating high-voltage resistant material, the radio frequency wire 21 is located in the middle of the first baffle piece 141 and is fixed by the first wire pressing plate 142, the radio frequency wire 21 is limited by the clamping blocks 1433 on the two sides of the second baffle piece 143 and is fixed by the second wire pressing plate 144, and the control wire 22 is arranged outside the first side plate 1412 on the two sides of the first baffle piece 141, above the first wire pressing plate 142 and in the middle of the second baffle piece 143, because the first baffle piece 141 and the second baffle piece 143 are designed with side plates and clamping blocks 1433, the radio frequency interference to the control signal is prevented.

[0049] In an embodiment, the first baffle piece 141 and the second baffle piece 143 are both made of silica gel material and have insulating effect. The two baffle pieces designed separately facilitate production and assembly, improve assembly efficiency, and also facilitate quality control.

[0050] In the embodiment of the utility model, the top of two first side plates 1412 is concave and is equipped with a limiting groove 1412A, the control line 22 passes through the control channel 112 on the second baffle piece 143, the limiting groove 1412A and the control channel 112 on the first baffle piece 141 in turn.

[0051] It is worth noting that, as Figure 4 , the limiting groove 1412A is used to limit and fix the control line 22, and the space is staggered at the position without support of the baffle between the first baffle piece 141 and the second baffle piece 143, so that the radio frequency line 21 and the control line 22 are pulled apart, the control line 22 keeps a certain distance from the radio frequency line 21, the control line 22 is prevented from being interfered, the path of static electricity propagation is reduced, and the static electricity protection performance is enhanced.

[0055] In addition, the electronic component 20 further comprises a third circuit board 25 connected to the two first side plates 1412, since the radio frequency wire 21 is located close to the radio frequency channel 111 of the first bottom plate 1411 and is separated by the first wire pressing plate 142, so that the third circuit board 25 is spaced apart from the radio frequency wire 21, and thus the interference of static electricity can be avoided. The third circuit board 25 is used for connecting the screen.

[0056] In the embodiment of the utility model, the wall surface of the upper shell 12 facing the lower shell 13 is provided with one of the female stop 121 and the male stop 131, the wall surface of the lower shell 13 facing the upper shell 12 is provided with the other one of the female stop 121 and the male stop 131, the female stop 121 and the male stop 131 are inserted and matched, and the hand tool 100 further comprises a first sealing element 30, which is arranged in the female stop 121 and abuts against the male stop 131.

[0057] In detail, by arranging the female stop 121 and the male stop 131 between the upper shell 12 and the lower shell 13, the upper shell 12 and the lower shell 13 can be inserted and matched through the female stop 121 and the male stop 131, the butt joint of the upper shell 12 and the lower shell 13 is designed as a double stop, that is, the female stop and the male stop are inserted and matched, which effectively increases the path of static electricity entering the inside of the hand tool 100, the first sealing element 30 is arranged between the female stop 121 and the male stop 131, is in the middle of the stop during assembly and is extruded, thereby eliminating the creepage gap at the female stop 121 and the male stop 131, effectively preventing or weakening the static electricity from entering the inside of the hand tool 100 through the interface gap between the upper shell 12 and the lower shell 13, forming an anti-static protection, preventing the harm to the electronic component 20 and improving the reliability and stability of the long-term use of the hand tool 100.

[0058] In addition, through the design of the double stop, the waterproof and dustproof ability of the hand tool 100 can be enhanced, and the internal electronic component 20 is protected from the influence of the external environment.

[0059] In the embodiment of the utility model, the middle part of the upper shell 12 and the lower shell 13 is arranged in a concave manner inward, and the surface of the upper shell 12 and the lower shell 13 is in an arc shape.

[0060] It is worth noting that, as Figure 1 The upper shell 12 and the lower shell 13 of the hand tool 100 are designed in an arc shape, which is more convenient for a person to hold, conforms to ergonomics, makes the hand tool 100 more fit the palm curve and reduces the fatigue feeling when holding for a long time, and simultaneously enhances the operation stability, so that the user can better control the hand tool 100.

[0062] Specifically, the first sealing gasket 61 is located between the cover plate 40 and the upper shell 12, fills the tiny gap between the first button hole 1221 and the first through hole 41, and prolongs the creepage path. The first boss 42 on the cover plate 40 is abutted on the first sealing gasket 61, ensuring that the first sealing gasket 61 is tightly attached around the first button hole 1221, that is, the first sealing gasket 61 is in the middle of the cover plate 40 and the upper shell 12 during assembly and is extruded, further enhancing the sealing effect, effectively eliminating the gap of creeping, effectively protecting or weakening the entry of static electricity at the button into the interior of the hand tool 100, and achieving good protection of the system in the interior of the hand tool 100. Meanwhile, the waterproof and dustproof capabilities of the upper shell 12 are enhanced, and the internal electronic components 20 are protected from the influence of the external environment.
