[0022] In the present solution, the temperature measuring device is an integrated structure, and is provided with a grip groove 101, which is convenient for the user to carry out hand-held operation. The wiring 113 is connected through the connector hole 110 on the screen 108, and the contact 114 at the other end of the wiring 113 is connected to the probe 115, so as to detect the temperature at the measuring point, and the reading is displayed on the screen 108.

[0024] Example 2 Please refer to Figure 4 and Figure 5As shown, the opening and closing mechanism 3 includes a threaded rod 301, a first movable member 302 and a second movable member. The threaded rod 301 is provided with two groups and is rotatably connected to the inner two sides of the machine box 107 respectively.

[0026] Example 3 Please refer to Figure 6 , Figure 7 and Figure 8 As shown, the mounting mechanism 2 includes a base plate 201, a first rack 205, a second rack 212 and a third rack 213.

The outer side of the shell 203 is penetrated by a through groove 217 for the first clamping member 210, the second clamping member 215 and the third clamping member 216 to pass through.

[0027] Please refer to Figure 8As shown, a mounting block 206 is fixedly installed at the inner bottom end of the shell 203, and a telescopic rod 208 is fixedly connected to the mounting block 206. A mounting groove 207 is penetrated through the first rack 205, and the telescopic end of the telescopic rod 208 is fixedly connected to the inner top end of the mounting groove 207, and a first spring 209 is sleeved on the outside of the telescopic rod 208.

[0028] In this solution, the principle of the installation mechanism 2 is as follows: when the screen 108 is installed, by inserting the bottom of the screen 108 into the first clamping member 210, under the gravity of the screen 108, the telescopic rod 208 and the first spring 209 are both in a contracted state, and then the first rack 205 moves downward, driving the gear 204 to rotate counterclockwise, so that the second rack 212 and the third rack 213 both move in a direction close to the gear 204 (such as Figure 7 As shown in the figure), the second clamping member 215 and the third clamping member 216 both move toward the direction close to the screen 108 to clamp the screen 108; and by providing a telescopic rod 208, which is a common structure in daily life and will not be elaborated on here, the stability of the overall movement of the first rack 205 and the first clamping member 210 is improved; and by providing a fixed rod 211 and a slide groove 214, the stability of the movement of the second rack 212 and the third rack 213 is improved.

One end of the first screw rod 402 is fixedly connected to the output end of the stepper motor 401, and the other end of the first screw rod 402 is rotatably connected to the inside of the connecting plate 403. The lifting member 406 is threadedly connected to the outer surface of the first screw rod 402.

[0030] Please refer to Fig.10 and Fig.11 As shown, the inner wall of the barrel 102 is also fixedly connected to a first fixed shaft, the outer surface of the first fixed shaft is rotatably connected to a first connecting arm 404 and a second connecting arm 405, and the inner wall of the sliding cylinder 105 is fixedly connected to a second fixed shaft, the outer surface of the second fixed shaft is rotatably connected to a third connecting arm 407 and a fourth connecting arm 408, two ends of one side of the telescopic member 409 are rotatably connected to the first connecting arm 404 and the second connecting arm 405 respectively, and two ends of the other side of the telescopic member 409 are rotatably connected to the third connecting arm 407 and the fourth connecting arm 408 respectively, and the lifting member 406 is fixedly connected to the telescopic member 409.

[0032] In this scheme, the principle of the telescopic mechanism 4 is as follows: the first screw rod 402 is driven to rotate through the output end of the stepper motor 401, so that the lifting member 406 moves up and down. When the lifting member 406 moves upward, the telescopic member 409 is in an extended state, driving the sliding cylinder 103, the sliding cylinder 2 104 and the sliding cylinder 3 105 to slide upward. When the lifting member 406 moves downward, the telescopic member 409 is in a retracted state, driving the sliding cylinder 103, the sliding cylinder 2 104 and the sliding cylinder 3 105 to slide downward. Therefore, the overall length of the device can be changed, so that the device can be well applied to measure the temperature at different heights or at different length positions.

[0033] Example 5 Please refer to Fig. 9 As shown, the clamping mechanism 5 includes a mounting frame 501, which is fixedly mounted on the top of the connecting member 111.

[0034] In this scheme, the principle of the clamping mechanism 5 is as follows: after the connector hole 110 is connected to the wiring 113, and the contact 114 at the other end of the wiring 113 is connected to the probe 115, by pulling the pull rod 505, several groups of second springs 502 are in a contracted state, and the wiring 113 is inserted into the interior of the two groups of pressing grooves 504, and the pull rod 505 is released. Under the action of the second spring 502 restoring the deformation, the clamping plate 503 is reset to achieve clamping of the wiring 113.

[0035] Example 6 Please refer to Fig.15 and Fig.16As shown, the head-changing mechanism 6 includes a servo motor 601, a second screw rod 604 and an L-shaped plate 606. The servo motor 601 is fixedly installed at the inner bottom end of the fixed disk body 106. The output end of the servo motor 601 is fixedly connected to the rotating disk 602. A plurality of fixed frames 603 are fixedly installed on the top of the rotating disk 602. One end of the second screw rod 604 is rotatably connected to the fixed frame 603. The other end of the second screw rod 604 is fixedly connected to an electric telescopic rod 607, and the electric telescopic rod 607 is also rotatably connected to the fixed frame 603. The output end of the electric telescopic rod 607 is fixedly connected to the first bevel gear 608. The vertical plate of the L-shaped plate 606 is threadedly connected to the outer surface of the second screw rod 604. A guide rod 605 is installed at the inner bottom end of the fixed frame 603. The L-shaped plate 606 is slidably connected to the outer surface of the guide rod 605. The inside of the horizontal plate of the L-shaped plate 606 is threadedly connected to the probe 115.

[0036] Please refer to Fig.17 As shown, the middle part of the top end of the rotating disk 602 is fixedly connected to the mounting plate 610 through a plurality of sets of fixing parts 609, a transmission motor 611 is installed on the top of the mounting plate 610, and a rotating shaft 612 is rotatably connected between the mounting plate 610 and the rotating disk 602, a second bevel gear 613 meshing with the first bevel gear 608 is fixedly connected to the middle part of the outer surface of the rotating shaft 612, and one end of the rotating shaft 612 is fixedly connected to the output end of the transmission motor 611.

[0037] In this solution, the principle of the head replacement mechanism 6 is as follows: when the probe 115 is replaced, the output end of the servo motor 601 drives the rotating disk 602 to rotate, so that the plurality of groups of probes 115 rotate, and then drives one group of probes 115 to move to the opening position of the fixed disk body 106, and then the output end of the electric telescopic rod 607 drives the first bevel gear 608 to mesh with the second bevel gear 613, and then the output end of the transmission motor 611 drives the rotating shaft 612 and the second bevel gear 613 to rotate, so that the first bevel gear 608 and the second bevel gear 613 are engaged with each other. The two screw rods 604 rotate as a whole, thereby driving the L-shaped plate 606 to move, so that the probe 115 extends out of the opening of the fixed disk body 106 for the user to use; it is worth mentioning here that when changing the head, the output end of the electric push rod 116 retracts, driving the contact 114 to move upward. After the probe 115 is replaced, the output end of the electric push rod 116 extends, driving the contact 114 to move downward.
