[0019] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Refer to Figure 1, showing a structural schematic diagram of a frequency conversion device of the present utility model, which may specifically include: a cylinder assembly 1, at least two high-frequency induction columns 2, at least two low-frequency induction columns 3, and a housing 4; the cylinder assembly 1 is arranged at the side end of the housing 4. It should be noted that the number of the high-frequency induction columns 2 is at least two, and preferably two are selected. The two are respectively connected to the positive and negative electrodes. Similarly, the number of the low-frequency induction columns 3 is also at least two, and preferably two are selected. It should also be noted that the number of the high-frequency induction columns 2 and the low-frequency induction columns 3 is preferably the same. For example, if the number of the high-frequency induction columns 2 is selected as two, then the number of the low-frequency induction columns 3 is also preferably two, which is convenient for the subsequent mechanism setting and to complete the high-frequency and low-frequency switching. In addition, the positions of the high-frequency induction columns 2 and the low-frequency induction columns 3 are not limited. It can be as Figure 1 shown, the high-frequency induction column 2 is above the low-frequency induction column 3, or the low-frequency induction column 3 is above the high-frequency induction column 2, and the positions of the two can be interchanged.

[0021] Furthermore, the cylinder assembly 1 is fixed to the side end of the housing 4 to prevent the cylinder assembly 1 from being unstable when the telescopic rod moves and causing damage due to falling.

[0022] Furthermore, a conductive frequency conversion mechanism 5 is provided at the push rod end of the cylinder assembly 1. It should be noted that the push rod end of the cylinder assembly 1 is fixedly connected to the frequency conversion mechanism 5, so as to realize the telescopic movement of the cylinder assembly 1, form the reciprocating movement of the frequency conversion mechanism, and realize frequency conversion.

[0023] Furthermore, the high-frequency induction columns 2 and the low-frequency induction columns 3 are respectively arranged on the housing 4 and on the same side end as the cylinder assembly 1. It should be noted that the high-frequency induction columns 2 and the low-frequency induction columns 3 are arranged on the housing 4 on the same side end as the cylinder assembly 1 in order to enable the cylinder assembly 1 to realize the function of frequency conversion through movement.

[0024] The frequency conversion mechanism 5 is arranged between the high-frequency induction column 2 and the low-frequency induction column 3, and contacts the induction point of the high-frequency induction column 2 at the first position and contacts the induction point of the low-frequency induction column 3 at the second position. It should be noted that after the frequency conversion mechanism 5 contacts the induction point of the high-frequency induction column 2, it is in the first state, and after the frequency conversion mechanism 5 contacts the induction point of the low-frequency induction column 3, it is in the second state. The state when the induction point of the high-frequency induction column 2 contacts the frequency conversion mechanism 5 is high frequency, and the state when the induction point of the low-frequency induction column 3 contacts the frequency conversion mechanism 5 is low frequency, specifically depending on the high-frequency induction column 2 and the low-frequency induction column 3. At the same time, the frequency conversion mechanism 5 is electrically conductive, so the high-frequency induction columns 2 can be connected in series or the low-frequency induction columns 3 can be connected in series through the induction points and the electrically conductive frequency conversion mechanism 5.

[0025] By setting the cylinder assembly and arranging the frequency conversion mechanism on the cylinder assembly, rapid and reliable frequency conversion can be achieved through the movement of the cylinder.

[0026] Combined with Figure 2 , the frequency conversion mechanism 5 includes a connecting member 52 and at least two frequency conversion columns 51. It should be noted that the number of the frequency conversion columns 51 should be the same as the number of the high-frequency induction columns 2 and the number of the low-frequency induction columns 3. More preferably, the number of the frequency conversion columns 51 is equal to the number of the high-frequency induction columns 2 and equal to the number of the low-frequency induction columns 3. Of course, it is not just two. Considering economy and practicality, two is just the best number that can just achieve the function and be stable.

[0027] Furthermore, the two frequency conversion columns 51 are connected by the connecting member 52 and arranged at the push rod end of the cylinder assembly 1. It should be noted that the frequency conversion mechanism 5 is electrically conductive, so both the frequency conversion columns 51 and the connecting member 52 must be made of electrically conductive materials, which can be plastics with built-in conductive cores. Considering cost and effect, the conductive cores often adopt copper compounds, phosphor bronze, nickel plating treatment, and there are also tin phosphor bronze and other copper-made ones, including but not limited to this. In addition, the connecting member 52 is fixed to the push rod end of the cylinder assembly 1 and can move up and down reciprocally together with the telescopic movement of the cylinder assembly 1. The frequency conversion columns 51 are connected by the connecting member 52 and are fixedly connected by the connecting member 52, and will also move up and down reciprocally with the telescopic movement of the cylinder assembly 1. It should also be added that more preferably, the frequency conversion columns 51 are symmetrically arranged with respect to the connecting member 52.

[0028] Further, the frequency conversion column 51 is disposed between the high-frequency induction column 2 and the low-frequency induction column 3, and contacts the induction point of the high-frequency induction column 2 at the first position and contacts the induction point of the low-frequency induction column 3 at the second position. It should be noted that the high-frequency induction column 2 and the low-frequency induction column 3 are respectively fixed on the housing. More preferably, the two high-frequency induction columns 2 are symmetrically arranged with respect to the cylinder assembly 1, and the two low-frequency induction columns 3 are also symmetrically arranged with respect to the cylinder assembly 1. The high-frequency induction column 2 is arranged above or below the low-frequency induction column 3, and their positional relationship can be interchanged. Moreover, the high-frequency induction column 2 and the low-frequency induction column 3 are cylinders with grooves at the top, and induction points are arranged in the grooves, while contact points are arranged at both ends of the frequency conversion column 51. When the frequency conversion column 51 contacts the induction point of the high-frequency induction column 2, the device is in a high-frequency state, and when the frequency conversion column 51 contacts the induction point of the low-frequency induction column 2, the device is in a low-frequency state.

[0029] Combined with Figure 3 , further explanation is as follows. The frequency conversion device further includes a control component 6, a power supply 7, and a switch button 8. The control component 6 is disposed inside the housing 4. The power supply 7 is disposed at the bottom of the housing 4. The switch button 8 is disposed on the side end of the housing 4. It should be noted that the control component 6 is used to perform overall control on each component. The power supply 7 provides power, and the switch button 8 controls the functions in the form of buttons. The required function can be achieved by pressing the button of the required function. The control component 6 can be a PCB (Printed Circuit Board) board with a chip set to perform overall control on each component. If you want to control the movement of the cylinder assembly 1 to control frequency conversion, an electric component needs to be set. This electric component is respectively connected to the control component 6, the switch button 7, the power supply 8, and the air valve of the cylinder assembly. By controlling the air valve of the cylinder assembly, the telescopic movement of the cylinder assembly 1 can be controlled, thereby achieving the control of frequency conversion. It is also possible to directly connect the air valve to a control valve, and pressing it can achieve the control of the telescopic movement of the cylinder assembly 1.

[0030] Further, the power supply 7 is electrically connected to the control component 6, the switch button 8, the cylinder assembly 1, the high-frequency induction column 2, and the low-frequency induction column 3 respectively. The control component 6 is electrically connected to the switch button 8 and the cylinder 1. Through the above connections, the controls of each part of the frequency conversion device are established. The downward penetration of the cylinder assembly 1 can be controlled through the settings on the switch button 8, driving the frequency conversion column 51 to contact the induction point of the low-frequency induction column 3 to achieve low frequency, or the upward movement of the cylinder assembly 1 can be controlled to drive the frequency conversion column 51 to contact the induction point of the low-frequency induction column 3 to achieve high frequency.

[0031] Further, the frequency conversion device further includes a filter 9; the filter 9 is disposed on the top of the housing 4; and is electrically connected to the power supply 7 and the control component 6 respectively. The function of the filter 9 is to reduce the leakage current to a safe range through filtering and shielding, so as to ensure the normal operation of the device and personal safety.

[0032] Further, the housing 4 is a cuboid with a detachable structure at the side end, which is convenient for subsequent inspection, maintenance and replacement of components.

[0033] Further, the switch button 8 includes at least on, off, high-frequency and low-frequency buttons. By setting specific buttons and corresponding functions, it is more convenient for manual operation to accurately control high frequency or low frequency.

[0034] Finally, it should also be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or terminal device comprising a series of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such process, method, article or terminal device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or terminal device comprising the element.
