[0025] For ease of understanding of the present invention, the present invention will be described more fully below in conjunction with specific embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] In one embodiment of the present invention, a fixing device is disclosed for fixing a sensor. The fixing device includes a connecting portion 50, a supporting portion 60 and a receiving portion 70. Figure 2 As shown in .

[0028] Please refer to Figure 2 and Figure 3 , Figure 4 The connecting portion 50 includes a connecting head 501 and a card holder 502. The connecting head 501 is embedded in the card holder 502 and passes through the card holder 502. Figure 3 As shown in , the card holder 502 has a through hole, and the connector 501 is inserted into the through hole. Further, the function of the connector 501 is to connect the sensor 10 and the data line 30. Therefore, in this embodiment, the connector 501 is a two-way connector, one end of which is connected to the sensor 10, and the other end is connected to the data line 30. More specifically, in this embodiment, the end of the connector 501 connected to the sensor 10 is a BNC male end, and is always connected to the sensor 10, while the end connected to the data line 30 is a BNC female end. Furthermore, a suction member 503 is provided on the side of the card holder 502 away from the sensor 10, that is, the card holder 502 is provided with a suction member 503 on the side away from the BNC male end of the connector 501. The suction member 503 is fixed on the card holder 502 in a conventional fixing manner in the art, such as welding, riveting, bonding, threaded connection, etc., which will not be elaborated here.

[0029] In this embodiment, the support portion 60 includes a suction ring 601 and a handpiece 602. Figure 5 As shown in the figure, when the suction ring 601 is close to the suction member 503, suction can be generated to fix it. In the embodiment, the suction member 503 is a magnetic block, and the suction ring 601 is a magnetic conductive ring. However, when the holder 502 is close to the suction ring 601, due to the magnetic suction, the suction ring 601 and the suction member 503 are adsorbed and fixed, thereby fixing the holder 502. Therefore, in order to further fix the suction ring 601 and the holder 502, as shown in the figure, Figure 4As shown in , the suction members 503 are evenly arranged along the edge of the holder 502, and their arrangement corresponds to the suction ring 601. Furthermore, the hand piece 602 is fixed on the outer wall of the suction ring 601, as shown in FIG. Figure 5 As shown in the figure, the axial direction of the handpiece 602 coincides with the radial direction of the suction ring 601. The handpiece 602 in this embodiment is a handle, which can be used for holding or fixing at other positions. It can be understood that the fixing method of the handpiece 602 and the suction ring 601 is a conventional method in the field, such as welding, integral forming, threaded connection, etc., which will not be described one by one here.

[0030] Furthermore, Figure 2 and Figure 6 As shown in , the fixing device in this embodiment further includes a receiving portion 70 for receiving the sensor 10 and the connecting portion 50. Preferably, the interior of the receiving portion 70 matches the sensor 10 to avoid shaking during reception. Further, see Figure 6 In the embodiment, an inner liner 701 is provided on the inner wall of the housing portion 70, and the inner liner 701 is made of soft material, so as to protect the sensor 10. The soft material here can be selected from soft rubber, soft foam or sponge, etc. It can be understood that it is not limited to the above-mentioned types. As long as the soft material can achieve the protection purpose, it can be used in the fixing device.

[0031] Under normal conditions, the sensor 10 and the BNC male end of the connector 501 of the connecting part 50 are always connected, and the sensor 10 and the connecting part 50 are placed together in the receiving part 70 for storage. When measuring, the sensor 10 and the connecting part 50 are taken out of the receiving part 70, and the data line 30 is passed through the suction ring 601 and connected to the BNC female end of the connector 501. The connecting part 50 is fixed by being adsorbed on the side of the suction ring 601 by the suction piece 503, and the hand piece 602 can be held or fixed at other positions, so as to realize the quick fixation of the sensor 10.

[0032] The fixing device can realize instant fixing through suction fixing, which is very convenient and avoids the time-consuming and residual adhesive pollution problems caused by the tape adhesion method; in addition, the fixing device in this embodiment uses the sensor 10 and the connecting part 50 to be always connected, stored and taken together, avoiding the increase of the operation steps of connecting the sensor 10 and the connector 501, thereby improving efficiency.

[0033] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
