[0021] See also Figure 1-4 , an embodiment provided by the utility model:

[0022] A hot wire probe for low noise signal transmission, comprising:

[0023] The device body includes a placement plate 100:

[0024] U-shaped plates 110 are fixedly installed on both sides of the top of the placement plate 100, a lower pressure plate 111 is arranged inside the U-shaped plate 110, a screw 113 is installed on the top of the lower pressure plate 111 through a bearing, an upper pressure plate 112 is arranged on the outer side of the screw 113, a support column 114 is fixedly installed on the top of the upper pressure plate 112, a threaded groove matching the screw 113 is provided inside the support column 114, a groove is provided inside the support column 114, a plug rod 115 is slidably installed inside the groove, a slot 116 is provided inside the plug rod 115, a return spring 117 is hingedly installed on one side of the inner wall of the slot 116, an elastic block 118 is fixedly installed on the outer side of the return spring 117, a limiting groove 119 matching the elastic block 118 is provided on the outer surface of the support column 114, A telescopic rod 120 is fixedly installed on one side, and a shaping hose 121 is arranged on the outer side of the telescopic rod 120. The bottom of the shaping hose 121 is connected to the hot wire probe through a clamp, and is placed in the U-shaped plate 110 through the lower pressure plate 111. The screw 113 is rotated to fix the lower pressure plate 111 and the upper pressure plate 112 on the U-shaped plate 110, and then the return spring 117 connected to the elastic block 118 is pressed into the slot 116. Through manual pressure, the insertion rod 115 is adjusted to the required height in the support column 114, so that the elastic block 118 rebounds to the required limit groove 119 for fixation. At the same time, the shaping hose 121 can be arbitrarily bent into a certain shape and can maintain its state. Through the arrangement of the above structure, the problem of inconvenient adjustment of the use height of the hot wire probe for low-noise signal transmission is solved.

[0025] Furthermore, anti-slip pads are provided on the sides of the upper pressing plate 112 and the lower pressing plate 111 that are close to each other.

[0026] Furthermore, the outer surface of the elastic block 118 is provided with a chamfer for preventing scratches.

[0027] Furthermore, a moving box 122 is installed at the bottom of the placement plate 100 by bolts, a motor 123 is installed at the top of the inner wall of the moving box 122, a connecting device 124 is installed at the bottom of the motor 123, a one-way threaded rod 125 is provided inside the connecting device 124, and the top of the one-way threaded rod 125 is connected to the inner wall of the moving box 122 through a bearing, a threaded sleeve 126 is installed on the outer side of the one-way threaded rod 125, T-shaped connecting rods 127 are fixedly installed on both sides of the threaded sleeve 126, and a universal wheel 128 is installed at the bottom of the T-shaped connecting rod 127. The number is four, because the general low-noise signal transmission hot wire probe instrument is not easy to move when in use, the instrument is placed on the placement plate 100, and the motor 123 is turned on to make the one-way threaded rod 125 do lifting and lowering movements on the connecting device 124, and the universal wheel 128 is moved outside the moving box 122 to facilitate the movement of the moving box 122. If it needs to be fixed, the universal wheel 128 is rotated into the moving box 122 to complete the fixation. The frame for storing the universal wheel 128 at the bottom of the moving box 122 increases the friction with the ground to prevent the moving box 122 from daily displacement.

[0028] Furthermore, vertical guide rods 129 are fixedly installed on both sides of the interior of the moving box 122, and a through slot is opened on the T-shaped connecting rod 127, and the vertical guide rods 129 are slidably installed inside the through slot.

[0029] Furthermore, shock-absorbing columns 130 are fixedly installed on both sides of the bottom of the T-shaped connecting rod 127 , and the bottom of the shock-absorbing column 130 is connected to the top of the universal wheel 128 .

[0030] Working principle: When in use, the lower pressing plate 111 is placed in the U-shaped plate 110, and the screw 113 is rotated to fix the lower pressing plate 111 and the upper pressing plate 112 on the U-shaped plate 110, and then the return spring 117 connected to the elastic block 118 is pressed into the slot 116, and the insertion rod 115 is adjusted to the required height in the support column 114 by manual pressure, so that the elastic block 118 rebounds to the required limit slot 119 for fixing, and at the same time, the shaping hose 121 can be arbitrarily bent into a certain shape and can maintain its state. The above-mentioned structure solves the problem of inconvenience in adjusting the low-noise signal. The problem of the height of the thermal wire probe for transmission is that the thermal wire probe instrument for low-noise signal transmission is generally not easy to move when in use. The instrument is placed on the placement plate 100, and the motor 123 is turned on to make the one-way threaded rod 125 move up and down on the connecting device 124, and the universal wheel 128 is moved outside the moving box 122 to facilitate the movement of the moving box 122. If it needs to be fixed, the universal wheel 128 is rotated into the moving box 122 to complete the fixation. The frame for storing the universal wheel 128 at the bottom of the moving box 122 increases the friction with the ground to prevent the moving box 122 from daily displacement.
