Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 3 , a completely freely telescopic temperature probe in this embodiment includes a first brass fastener 1. A placement hole 2 is formed in the left side surface of the first brass fastener 1. A brass temperature sensing element 9 is placed inside the placement hole 2, and one end of the brass temperature sensing element 9 penetrates through the placement hole 2 and extends to the left side of the first brass fastener 1.

[0021] A connection hole 13 is formed in the right side surface of the first brass fastener 1. A temperature sensing element 10 is placed inside the brass temperature sensing element 9. The inside of the brass temperature sensing element 9 is filled with a rubber material 11. A spring 4 is placed inside the placement hole 2, and the spring 4 is fixedly connected to the first brass fastener 1. A wire 12 is fixedly connected to the temperature sensing element 10, and one end of the wire 12 penetrates through the placement hole 2 and the connection hole 13 and extends to the right side of the first brass fastener 1.

[0022] Among them, the temperature sensing element 10 is in contact with the brass temperature sensing element 9. The temperature sensing element 10 and the rubber material 11 are encapsulated together inside the brass temperature sensing element 9. The wire 12 is located inside the spring 4, and the wire 12 penetrates through the rubber material 11 and is fixedly connected to it. The spring 4 is in contact with the brass temperature sensing element 9.

[0023] It should be noted that the temperature sensing element 10 is a conventional device well known to the public in the prior art, and its specific structure and working principle will not be elaborated herein.

[0024] Specifically, the temperature sensing element 10 and the rubber material 11 are encapsulated inside the brass temperature sensing element 9. Push the brass temperature sensing element 9 so that the brass temperature sensing element 9 enters the inside of the placement hole 2 and then comes into contact with the spring 4. The brass temperature sensing element 9 is pressed down by the gravity of the object to be temperature sensed. At the same time, the spring 4 provides an upward elastic force to make the brass temperature sensing element 9 contact the object. When the object separates, the spring 4 rebounds to reset the brass temperature sensing element 9. Under the action of the temperature sensing element 10, the temperature sensing object is measured.

[0025] In this embodiment, a limiting component is provided on the first brass fastener 1. The limiting component includes a second brass fastener 8. The second brass fastener 8 is placed on the left side of the first brass fastener 1. A threaded hole 6 is formed in the right side surface of the second brass fastener 8. A partition 5 is fixedly sleeved on the outer peripheral wall of the first brass fastener 1. A first threaded groove 7 is formed in the outer peripheral wall of the first brass fastener 1, and the first threaded groove 7 extends into the threaded hole 6. A second threaded groove 3 is formed in the outer peripheral wall of the first brass fastener 1. A relief hole 14 is formed in the left side surface of the second brass fastener 8, and the brass temperature sensing element 9 penetrates through the relief hole 14.

[0026] Among them, the first threaded groove 7 is threadedly connected to the threaded hole 6. The second brass fastener 8 is in contact with the partition 5. The first threaded groove 7 is located on the left side of the partition 5, and the second threaded groove 3 is located on the right side of the partition 5.

[0027] Specifically, rotate the second brass fastener 8, and the brass temperature sensor 9 passes through the relief hole 14. Through the threaded connection between the first threaded groove 7 and the threaded hole 6, the second brass fastener 8 is fixed on the first brass fastener 1 to restrict the brass temperature sensor 9. Then, under the action of the second threaded groove 3, the first brass fastener 1 is fixed on an external object.

[0028] The working principle of the above embodiment is as follows:

[0029] The temperature sensing element 10 and the rubber 11 are encapsulated inside the brass temperature sensor 9. Push the brass temperature sensor 9 to make it enter the inside of the placement hole 2, and then it fits with the spring 4. Rotate the second brass fastener 8, and the brass temperature sensor 9 passes through the relief hole 14. Through the threaded connection between the first threaded groove 7 and the threaded hole 6, the second brass fastener 8 is fixed on the first brass fastener 1 to restrict the brass temperature sensor 9. Then, under the action of the second threaded groove 3, the first brass fastener 1 is fixed on an external object. The brass temperature sensor 9 is pressed down by the gravity of the object to be sensed. At the same time, the spring 4 provides an upward elastic force to make the brass temperature sensor 9 fit with the object. When the object to be sensed separates, the spring 4 rebounds to reset the brass temperature sensor 9. Under the action of the temperature sensing element 10, the temperature of the object to be sensed is measured.
