[0019] The utility model will be specifically explained in connection with the drawings.

[0020] As shown in the drawings Figure 1 to the drawings Figure 4 ,

[0021] Embodiment:

[0022] The VOCs monitor adapter rod has an elastic fixing clip, including a fixed plate 1, a hoop plate 2, and two movable plates 3. The fixed plate 1 is equipped with a VOCs monitor 4. The two movable plates 3 are symmetrically arranged on both sides of the fixed plate 1. The hoop plate 2 is located at the front end of the fixed plate 1. The inner sides of the fixed plate 1, hoop plate 2, and the two movable plates 3 are all arc-shaped. The movable plates 3 have mounting holes 5 inside, and a limiting post 6 for fixing and connecting the fixed plate 1 is installed inside the mounting holes 5. A spring 7 is sleeved on the outer side of the limiting post 6, and a baffle for fixing and connecting the movable plates 3 is installed on the outer side of the mounting holes 5. 8. A guide hole 9 is provided in the center of the baffle 8. The limiting post 6 passes through the guide hole 9. A pin hole 10 is provided on the side of the movable plate 3 near the hoop plate 2. A guide block 11 is provided below the opening side of the pin hole 10. A slide groove 12 is provided in the middle of the guide block 11. A slider 13 is slidably connected in the slide groove 12. One end of the slider 13 is fixedly connected to the hoop plate 2. A pin block 14 is fixed to the other end of the slider 13. The width of the pin block 14 is greater than that of the slide groove 12. The side of the two guide blocks 11 that is far apart is the guide surface 15. The pin block 14 can slide along the guide surface 15 into the pin hole 10.

[0023] Preferably, the guide surface 15 includes an inclined surface 151 and a horizontal surface 152, a first arc-shaped connecting surface 153 is provided between the inclined surface 151 and the horizontal surface 152, and a second arc-shaped connecting surface 154 is provided between the inclined surface 151 and the bottom surface of the pin hole 10.

[0024] The elastic clamp in this embodiment is in the following state when opened: Figure 1 and 3 As shown, at this time, under the action of the springs 7 on both sides, the two movable plates 3 are pushed open to both sides, and the pin block 14 is located on the horizontal plane 152 of the guide surface 15. Since the width of the pin block 14 is greater than that of the slide groove 12, it will prevent the spring 7 from pushing the movable plates 3 further to both sides. When it is necessary to fix the VOCs monitor 4, the rod used to fix the VOCs monitor 4 is passed through the center hole of the fixed plate 1, the hoop plate 2 and the two movable plates 3. The hoop plate 2 is pushed by hand to move to one side of the fixed plate 1. At this time, the slider 13 slides along the slide groove 12. Furthermore, the pin 14 moves upward along the guide surface 15, generating an inward force. This force drives the baffle 8 on the movable plate 3 to compress the spring 7. The two movable plates 3 move closer to the fixed plate 1 until the pin 14 is fully engaged in the pin hole 10, completing the fixation with the rod. Throughout the process, the two movable plates 3 and the clamp plate 2 move towards the fixed plate 1, thereby reducing the size of the central hole between the three, thus locking them onto the rod. Due to the outward elastic force of the spring 7, the pin 14 is not easily dislodged from the pin hole 10, making the locking more secure. The movable plate 3 and the fixed plate 1 are elastically connected, and the elastic clamp automatically springs open and separates when released, facilitating disassembly.

[0025] The end of the limiting column 6 extending outside the baffle 8 is provided with a nut 16, and the end of the limiting column 6 close to the fixed plate 1 is provided with a thread, which is connected with the screw hole on the fixed plate 1. The limiting column 6 is in the shape of a bolt, which facilitates the assembly between the fixed plate 1 and the movable plate 3, and the nut 16 on the top can also avoid the movable plate 3 from being pulled out due to the action of the spring 7.

[0026] The side of the fixed plate 1 away from the hoop plate 2 is provided with a U-shaped connecting plate 17, which is fixedly connected with the lug plate 19 on the VOCs monitor 4 through a bolt 18. After the lug plate 19 is inserted into the U-shaped connecting plate 17, it is fixed through the bolt 18, and the VOCs monitor 4 and the elastic fixing clamp can be separated and disassembled according to the requirement.

[0027] The side of the hoop plate 2 away from the fixed plate 1 is provided with a pull ring 20, which is used for pushing and pulling the hoop plate 2.

[0028] The arc surfaces of the fixed plate 1 and the hoop plate 2 are both provided with rubber pads 21, which increase the friction between the rubber pads 21 and the rod body and avoid slipping.

[0029] The bottom of the pin hole 10 is provided with a sawtooth groove, and the bottom of the pin block 14 is provided with a plurality of corresponding protrusions. When the protrusions are clamped into the sawtooth groove, the friction can be increased, and the separation of the hoop plate 2 and the movable plate 3 during the fixing can be avoided, so that the elastic fixing clamp is loosened.

[0030] Although the utility model has disclosed as above with preferred embodiments, they are not used to limit the utility model, any skilled person in the art can make various changes or decorations without departing from the spirit and scope of the utility model, therefore the protection scope of the utility model should be limited by the protection scope of the claims of the application.
