[0011] Preferably, the upper end of the spring is fixed to the inner upper surface of the arc-shaped cover plate, and the lower end of the spring is fixed to the cushion block.
[0012] Preferably, the wire passes through the handle and is fixed to the probe.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] In the utility model, by setting the adjusting block, the arc-shaped cover plate, the arc-shaped pressing plate and the arc-shaped supporting plate to cooperate with each other, when the wire is not in use, rotate the knob of the adjusting block, the knob drives the threaded rod to rotate, and the rotating threaded rod causes the arc-shaped cover plate to move upward. When the arc-shaped cover plate rises to a certain height, the coiled wire can be hung on the arc-shaped supporting plate. Finally, rotate the knob in the reverse direction to make the arc-shaped cover plate descend. When the arc-shaped cover plate descends a certain height, the arc-shaped pressing plate will contact the wire. As the arc-shaped cover plate continues to descend, the spring of the arc-shaped pressing plate will be compressed, so that the wire on the arc-shaped supporting plate can be pressed tightly by the arc-shaped pressing plate, thereby ensuring the stability of the wire placement.

Detailed Embodiment
[0019] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with the specific embodiments.
[0020] As Figures 1-3 shown, a fast-response platinum resistance temperature sensor includes a probe 1, a handle 2 and a wire 3. The upper end of the probe 1 is fixedly installed with a handle 2, the upper surface of the probe 1 is fixedly installed with a wire 3, the surface of the handle 2 is fixedly installed with an adjusting block 4, the surface of the adjusting block 4 is movably installed with an arc-shaped cover plate 5, the inside of the arc-shaped cover plate 5 is provided with an arc-shaped pressing plate 6, and the lower end of the adjusting block 4 is fixedly installed with an arc-shaped supporting plate 7.
[0021] A knob 401 is movably installed on the upper surface of the adjusting block 4. A lifting groove 402 is formed inside the adjusting block 4. A threaded rod 403 is fixedly installed on the lower surface of the knob 401. The lower end of the threaded rod 403 extends into the lifting groove 402. The rotating threaded rod 403 can control the lifting of the arc-shaped cover plate 5. Connecting blocks 701 are fixedly installed on the rear surfaces of both sides of the arc-shaped support plate 7. The arc-shaped support plate 7 is fixed to the adjusting block 4 through the connecting blocks 701. A cushion block 601 is fixedly installed on the upper surface of the arc-shaped pressing plate 6. A guide rod 602 is fixedly installed on the upper surface of the cushion block 601. The guide rod 602 penetrates through the arc-shaped cover plate 5. A stop block 603 is fixedly installed on the upper surface of the guide rod 602. A spring 604 is sleeved on the surface of the guide rod 602 below the arc-shaped pressing plate 6. The spring 604 has a downward pushing force on the cushion block 601. A threaded sleeve block is fixedly installed on the rear surface of the arc-shaped cover plate 5. The threaded sleeve block is sleeved on the surface of the threaded rod 403 inside the lifting groove 402. The upper end of the spring 604 is fixed to the inner upper surface of the arc-shaped cover plate 5. The lower end of the spring 604 is fixed to the cushion block 601. The wire 3 passes through the handle 2 and is fixed to the probe 1.
[0022] It should be noted that the present invention is a fast-response platinum resistance temperature sensor. When in use, when the wire 3 is not used, rotate the knob 401 of the adjusting block 4. The knob 401 drives the threaded rod 403 to rotate. The rotating threaded rod 403 causes the arc-shaped cover plate 5 to move upward. When the arc-shaped cover plate 5 rises to a certain height, the coiled wire 3 can be hung on the arc-shaped support plate 7. Finally, rotate the knob 401 in the reverse direction to make the arc-shaped cover plate 5 descend. When the arc-shaped cover plate 5 descends a certain height, the arc-shaped pressing plate 6 will contact the wire 3. As the arc-shaped cover plate 5 continues to descend, the spring 604 of the arc-shaped pressing plate 6 will be compressed. In this way, the wire 3 on the arc-shaped support plate 7 can be pressed tightly by the arc-shaped pressing plate 6, so as to ensure the stability of the wire 3 during placement.
