[0013] The present invention has the beneficial effects:

[0014] The pressure plate of the present invention slides along the sliding groove, so that the slide rod slides along the limiter. When the circular groove slides to the outside of the rear plate, the pressure plate moves downward along the sliding groove, and the circular groove moves along the slide rod until the parallel plate is close to the ground, and then the ruler is opened.

[0015] During measurement, the upper ruler is rotated along the hinge to the top of the lower ruler, and the circular groove on the rotating clamp is clamped onto the clamping column on the upper ruler, so that the smooth side of the ruler is close to the wall. The horizontal pointer is observed. When the pointer points to 0, it indicates that the wall is perpendicular to the ground. When the pointer deviates to the left, it indicates that the wall is tilted to the right. When the pointer deviates to the right, it indicates that the wall is tilted to the left. This avoids the problem of being unable to visually observe whether the wall is perpendicular to the ground during inspection.

[0016] The present invention draws the gas to be measured into a measuring chamber. An infrared lamp is installed at one end of the measuring chamber and a filter and a detector are installed at the other end. The filter is used to allow only light of a specific wavelength to pass through, and the detector measures the light flux passing through the measuring chamber. The light flux received by the detector depends on the concentration of the gas to be measured in the environment, thereby determining the carbon dioxide content in the air.

[0017] The inlet manifold of the present invention draws a certain volume of dust-laden air through the air intake. The dust is retained on the filter paper, and a light beam shines through the filter paper onto the silicon photocell. Changes in the illumination received by the silicon photocell cause changes in the output current intensity of the silicon photocell. Within a certain range, the amount of dust retained by the filter paper and the output current of the silicon photocell are linearly proportional, and this is displayed by an indicator light according to a calculation program set in the detector.

[0018] The present invention soaks the test paper in a coloring agent. When gas is blown onto the test paper soaked with the coloring agent, the formaldehyde contacts the paper and the reagent contained in the paper reacts with the formaldehyde to generate a compound, causing the color to change from white to yellow. The degree of color change can reflect the amount of reflected light received, and the intensity change rate of the reflected light can be used as a corresponding gas concentration. The formaldehyde concentration in the air can be judged based on the degree of color change of the test paper.

[0019] When the switch is activated, the hydraulic secondary rod drives the scale belt upward to the roof, where the floor height can be measured by observing the scale belt. A soft cushion is placed on the top of the hydraulic secondary rod to prevent the floor height meter from being damaged by impacts when reaching the roof. This also prevents vibrations that could reduce the device's lifespan.

[0020] The present invention starts switch two, and the hydraulic secondary rod two drives the circular groove two to rise upward until it reaches the measuring position, pushes the circular groove two to make the ruler close to the wall, rotates the caliper close to the wall corner, observes the position of the ruler and the caliper, and judges whether the Yin-Yang angle is compliant.

[0021] The roller provided in the present invention can arbitrarily place the instrument at any measuring point that needs to be measured during the acceptance process, saving the time and energy consumed by manual handling. During measurement, the pedal is stepped on, and the pedal drives the pressure column to move downward, and the pressure column drives the baffle to be pulled outward. After the baffle is pulled outward, the rotating shaft slides upward along the groove, and the roller is hidden in the groove of the bottom plate. The bottom plate is close to the ground. Anti-skid teeth are provided on the surface of the roller to increase friction, thereby preventing the wheel from slipping during operation.

[0022] The present invention toggles the toggle rod, which drives the pull rod, which drives the knocking column to move up and down, and the hammer head fixedly connected to the knocking column knocks the ground to check the hollowing condition. When the hollowing hammer is not in use, the knocking column is rotated upward and clamped on the clamp. BRIEF DESCRIPTION OF THE DRAWINGS

The filter 102 is used to allow only light of a specific wavelength to pass through, and the detector 101 measures the light flux passing through the measuring chamber. The light flux received by the detector 101 depends on the concentration of the measured gas in the environment.

[0040] In the present invention, air intake manifold 72 draws a certain volume of dust-laden air through air intake 7. Dust is trapped on filter paper 114. A light beam passes through filter paper 114 and strikes silicon photocell 113. Changes in the illumination received by silicon photocell 113 cause changes in the output current intensity. Within a certain range, the amount of dust trapped by filter paper 114 and the output current of silicon photocell 113 are linearly correlated. This is displayed by indicator light 111, using a program programmed within the detector.

[0041] In the present invention, the test paper 121 is soaked in a colorant. When gas is blown onto the test paper 121 soaked in the colorant, the formaldehyde contacts the paper and the reagent contained in the paper reacts with the formaldehyde to form a compound, causing the color to change from white to yellow. The degree of color change can reflect the amount of reflected light received, and the intensity change rate of the reflected light can be used as a corresponding indicator of the gas concentration. The formaldehyde concentration in the air can be determined based on the degree of color change of the test paper 121.

[0042] When the switch 88 is activated, the hydraulic secondary rod 81 drives the scale belt 84 upward to the roof, where the floor height can be measured by observing the scale belt 84. A cushion 86 is provided on the top of the hydraulic secondary rod 81 to prevent damage to the roof surface caused by the floor height measuring device 8 upon reaching the roof. This also prevents vibration to the device, which could reduce its lifespan.

[0043] The present invention starts switch 2 96, and hydraulic secondary rod 2 93 drives circular groove 2 92 to rise upward until it reaches the measuring position, pushes circular groove 2 92 to make scale 91 close to the wall, rotates caliper 98 close to the wall corner, observes the position of scale 91 and caliper 98, and judges whether the Yin-Yang angle is compliant.

[0044] The present invention is provided with a roller 164, which can arbitrarily place the instrument at any measuring point that needs to be measured during the acceptance process, saving the time and energy consumed by manual handling. During measurement, the pedal 15 is stepped on, and the pedal 15 drives the pressure column 151 to move downward, and the pressure column 151 drives the baffle 162 to be pulled outward. After the baffle 162 is pulled outward, the rotating shaft 163 slides upward along the groove, and the roller 164 is hidden in the groove of the bottom plate 17. The bottom plate 17 is close to the ground. The surface of the roller 164 is provided with anti-skid teeth 164 to increase friction and prevent the wheel from slipping during operation.

[0045] The present invention toggles the lever 20, the lever 20 drives the pull rod 137, the pull rod 137 drives the knocking column 136 to move up and down, and the hammer head 135 fixedly connected to the knocking column 136 knocks the ground to check the hollowing condition. When the hollowing hammer is not in use, the knocking column 136 is rotated upward and the knocking column 136 is clamped on the clamp 139.

[0046] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
