[0029] The outer wall of the electronic measuring and controlling instrument 5 is in contact with the outer wall of the clamping plate 16, so that the spring 15 and the telescopic rod 14 are contracted, and at the same time, the top of the electronic measuring and controlling instrument 5 is in contact with the bottom of the clamping plate 2 19, and then under the action of the spring 2 18 and the spring 15, the clamping plate 16 clamps the left and right sides of the electronic measuring and controlling instrument 5, and the clamping plate 2 19 clamps the top of the electronic measuring and controlling instrument 5, thereby the electronic measuring and controlling instruments 5 of different sizes can be clamped and fixed, thereby achieving a fixing effect.

[0030] like Figure 2 As shown, a pad 23 is fixedly connected to the bottom end of the damper 21 , and a shock absorbing spring 22 is fixedly connected to the bottom of the inner cavity of the damper 21 .

[0031] When the electronic measuring and controlling instrument 5 is placed in the protection box 1, the vibration generated is absorbed by the damper 21 and the shock absorbing spring 22, thereby reducing the impact of the vibration, avoiding damage to the electronic measuring and controlling instrument 5, and achieving a shock absorbing effect.

[0032] like Figure 2 , Figure 3 As shown, the output end of the motor 31 is fixedly connected to a rotating rod 32, the left end of the rotating rod 32 is rotatably connected to the bottom of the left end of the inner cavity of the protection box 1, the right part of the rotating rod 32 is transmission-connected to a conveyor belt 33, the rear part of the conveyor belt 33 is transmission-connected to a rotating shaft 34, and the outer wall of the rotating shaft 34 is rotatably connected to the bottom of the protection box 1.

[0033] By starting the motor 1 31 , the rotating rod 32 is driven to rotate, the rotating rod 32 drives the transmission belt 33 to rotate, and the transmission belt 33 drives the rotating shaft 34 to rotate synchronously.

[0035] When the rotating rod 32 and the rotating shaft 34 rotate, the worm 35 is driven to rotate synchronously, so that the outer wall of the worm 35 is meshed with the worm wheel 36, driving the worm wheel 36 to rotate synchronously, and the worm wheel 36 drives the sleeve block 361 to rotate synchronously, so that the screw 362 slides on the inner wall of the sleeve block 361, and the screw 362 drives the support plate 37 to move upward, and the support plate 37 drives the electronic measuring and controlling instrument 5 to move upward synchronously, so that the top end of the electronic measuring and controlling instrument 5 is in close contact with the bottom end of the clamping plate 2 19, so that the telescopic rod 2 17 and the spring 2 18 are contracted, and then under the action of the spring 2 18 and the spring 1 15, the clamping plate 1 16 clamps the left and right sides of the electronic measuring and controlling instrument 5, and the clamping plate 2 19 clamps the top of the electronic measuring and controlling instrument 5, thereby the electronic measuring and controlling instruments 5 of different sizes can be clamped and fixed, thereby achieving a fixing effect.

[0036] like Figure 2 , Figure 4 As shown, the left and right ends of the support plate 37 are fixedly connected with limit blocks 371, the outer wall of the limit block 371 is slidably connected to the bottom of the protection box 1, the shape of the limit block 371 is T-shaped, and the top of the support plate 37 is fixedly connected with an anti-sliding block 372 in a linear array, and the top of the anti-sliding block 372 overlaps with the bottom end of the electronic measurement and control instrument 5.

[0037] When the support plate 37 moves, it drives the limit block 371 to slide on the inner wall of the protection box 1. The limit block 371 limits the support plate 37 so that when the support plate 37 slides to the maximum distance, it cannot continue to slide. At the same time, it also prevents the screw rod 362 from escaping from the inner wall of the sleeve block 361.

[0038] like Figure 2 As shown, a filter screen 42 is fixedly connected to the top of the fixed box 41, a fixed plate 43 is fixedly connected to the top of the inner cavity of the fixed box 41, a motor 2 44 is fixedly connected to the bottom end of the fixed plate 43, and four fan blades 45 are fixedly connected to the outer wall of the output end of the motor 2 44 in a circular array.

[0039] By starting the second motor 44, the fan blades 45 are driven to rotate, and the hot air flow in the protection box 1 is discharged through the filter 42, so as to dissipate the heat from the inner cavity of the protection box 1, thereby preventing the temperature in the protection box 1 from being too high and causing damage to the electronic measurement and control instrument 5. At the same time, the filter 42 prevents external dust from entering the protection box 1, thereby achieving the effect of heat dissipation and dust prevention.

[0040] The working principle of the utility model is as follows: when in use, the electronic measuring and controlling instrument 5 is placed on the supporting plate 37, so that the bottom end of the electronic measuring and controlling instrument 5 contacts the top end of the anti-sliding block 372, and at the same time, the outer wall of the electronic measuring and controlling instrument 5 contacts the outer wall of the abutting plate 16, so that the spring 15 and the telescopic rod 14 are contracted, and at the same time, the top end of the electronic measuring and controlling instrument 5 contacts the bottom end of the abutting plate 19, and then the motor 131 is started to drive the rotating rod 32 to rotate, the rotating rod 32 drives the transmission belt 33 to rotate, and the transmission belt 33 drives the rotating shaft 34 to rotate synchronously, thereby driving the worm 35 to rotate synchronously. The worm 35 is rotated step by step, so that the outer wall of the worm 35 is meshed with the worm wheel 36, driving the worm wheel 36 to rotate synchronously, and the worm wheel 36 drives the sleeve block 361 to rotate synchronously, so that the screw 362 slides on the inner wall of the sleeve block 361, and the screw 362 drives the support plate 37 to move upward. At the same time, the support plate 37 drives the limit block 371 to slide on the inner wall of the protection box 1, and the limit block 371 limits the support plate 37, so that when the support plate 37 slides to the maximum distance, it cannot continue to slide, and at the same time, it also prevents the screw 362 from escaping from the inner wall of the sleeve block 361, thereby making the support plate 37 carry The electronic measuring and controlling instrument 5 is synchronously moved upward, so that the top of the electronic measuring and controlling instrument 5 is in close contact with the bottom of the second clamping plate 19, so that the telescopic rod 17 and the second spring 18 are contracted, and then under the action of the second spring 18 and the first spring 15, the first clamping plate 16 clamps the left and right sides of the electronic measuring and controlling instrument 5, and the second clamping plate 19 clamps the top of the electronic measuring and controlling instrument 5, thereby the electronic measuring and controlling instruments 5 of different sizes can be clamped and fixed, and the fixing effect is achieved. When the electronic measuring and controlling instrument 5 is placed, the vibration generated is damped by the damper 21 The shock-absorbing spring 22 absorbs the vibration, thereby reducing the impact of the vibration, avoiding damage to the electronic measuring and controlling instrument 5 and achieving a shock-absorbing effect. When the electronic measuring and controlling instrument 5 is stored, the motor 2 44 is started to drive the fan blades 45 to rotate, and the hot air flow in the protection box 1 is discharged through the filter 42 to dissipate the heat from the inner cavity of the protection box 1 to prevent the temperature in the protection box 1 from being too high and causing damage to the electronic measuring and controlling instrument 5. At the same time, the filter 42 prevents external dust from entering the protection box 1, achieving a heat dissipation and dustproof effect, thereby greatly improving the user experience.
