When the staff pulls the extension rod 7 downward to move, the extension rod 7 moves and simultaneously pulls the return spring 15 to extend to accumulate force. When the staff releases the fixation of the position of the extension rod 7, the return spring 15 releases the force generated by the rebound to pull the extension rod 7 upward to reset the position of the extension rod 7, making it convenient for the staff to retract the extension rod 7.

[0032] Reference Figure 5 As shown, in the present embodiment: a first threaded hole 16 is opened on one side of the mounting shell 3, and a screw 17 is threadedly connected to the inner wall of the first threaded hole 16.

[0033] Reference Figure 2 As shown, in this embodiment: the top of the ground plug 10 is fixedly connected with a connecting rope 18, and the other end of the connecting rope 18 is fixedly connected to the top of the supporting leg 9. The ground plug 10 is connected to the supporting leg 9 by setting the connecting rope 18, and the position of the ground plug 10 is fixed to prevent the ground plug 10 from being lost when the staff is carrying the device.

[0034] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in the present embodiment: the extension shell 2 and the extension rod 7 are both made of aluminum alloy. By making the extension shell 2 and the extension rod 7 of aluminum alloy, the extension shell 2 and the extension rod 7 have higher hardness, are not easy to deform, and are corrosion-resistant. They are not easy to bend and deform during long-term use to affect the measurement quality of the device, thereby improving the service life of the device.

[0035] Reference Figure 6 and Figure 7 As shown, in the present embodiment: second threaded holes 19 are provided on both sides of the front end of the mounting frame 1, the inner wall of the second threaded hole 19 is threadedly connected with a threaded knob 20, the surface of the threaded knob 20 is slidably connected with a clamping plate 21, the bottom of the mounting frame 1 is fixedly connected with an extension plate 22, the bottom of the extension plate 22 is fixedly connected with a tray 23, the staff places the measuring book on the top of the tray 23, and then screws the threaded knob 20 into the inner wall of the second threaded hole 19, so that the threaded knob 20 presses the clamping plate 21 to clamp and fix the measuring book, and the measuring book is fixed to the front end of the mounting frame 1, so that the staff can record the real-time measurement results.

[0036] Reference Figure 7As shown, in the present embodiment: circular holes 24 are provided on both sides of the tray 23, and the rear end of the bottom of the clamp 21 is fixedly connected with a limiting rod 25, and the surface of the limiting rod 25 is slidably connected with the inner wall of the circular hole 24.

When the staff turns the threaded knob 20 to press the clamping plate 21 to clamp the measuring book, the clamping plate 21 drives the limit rod 25 to move backward, and the round block 26 pulls the second spring 27 to accumulate force. When the staff releases the threaded knob 20 to press the clamping plate 21, the second spring 27 releases the force generated, so that the second spring 27 rebounds and pulls the round block 26 to push the limit rod 25 to drive the clamping plate 21 to move forward, thereby opening the clamping of the clamping plate 21 to the measuring book, making it convenient for the user to take out the measuring book.

[0038] Working principle: the staff presses the plug plate 5 inward to pull the first spring 6 to extend and store force, and then pulls the extension rod 7 to slide to the specified position in the inner wall of the extension shell 2, and then releases the plug plate 5 to release the force generated by the first spring 6, so that the first spring 6 rebounds and pushes the top of the plug plate 5 to insert into the inner wall of the limiting hole 8, and fixes the position of the extension rod 7, which is convenient for the staff to adjust the height of the extension rod 7 according to needs, realizes the telescopic storage of the extension rod 7, and reduces the occupied space of the device for easy carrying. When the plug plate 5 moves under the elastic force of the first spring 6, the sliding rod 12 on the inner wall of the first spring 6 is connected with the inner wall of the first slide groove 11 through sliding connection, so as to limit the elastic force trajectory of the first spring 6 and the movement trajectory of the plug plate 5, so that the plug plate 5 The top of the extension rod 7 is more accurately plugged into the limiting hole 8, making the operation of the component more stable. When the staff pulls the extension rod 7 to move, the sliding connection between the slide plate 14 and the second slide groove 13 is used to limit the movement trajectory of the extension rod 7, and the position of the extension rod 7 is limited to the inner wall of the extension shell 2, preventing the staff from pulling the extension rod 7 out of the inner wall of the extension shell 2 and causing the component to separate. When the staff pulls the extension rod 7 downward to move, the extension rod 7 moves and pulls the reset spring 15 to extend and store force. When the staff releases the fixation of the position of the extension rod 7, the reset spring 15 releases the force generated by the rebound to pull the extension rod 7 upward to reset the position of the extension rod 7, which is convenient for the staff to retract the extension rod 7. When the staff inserts the plug plate 5 into the limiting After the plug plate 5 is inserted into the inner wall of the limiting hole 8, the screw 17 is screwed inward to push into the bottom of the plug plate 5 to restrain the position of the plug plate 5 to prevent the plug plate 5 from being detached from the limiting hole 8 due to the vibration of the assembly after the plug plate 5 is plugged into the limiting hole 8. The ground plug 10 is connected to the support leg 9 by setting a connecting rope 18 to fix the position of the ground plug 10 to prevent the staff from losing the ground plug 10 when carrying the device. The extension shell 2 and the extension rod 7 are made of aluminum alloy material, so that the extension shell 2 and the extension rod 7 have higher hardness, are not easy to deform, and are corrosion-resistant. They are not easy to bend and deform after long-term use to affect the measurement quality of the device, thereby improving the service life of the device. The staff places the meter on the top of the tray 23, and then screws the threaded knob 20 into the second threaded hole 19 The inner wall of the measuring book is formed so that the threaded knob 20 presses the clamping plate 21 to clamp and fix the measuring book, and the measuring book is fixed to the front end of the mounting frame 1, which is convenient for the staff to record the real-time measurement results. When the staff turns the threaded knob 20 to push the clamping plate 21 to clamp the measuring book, the sliding connection between the limit rod 25 and the circular hole 24 restricts the movement trajectory of the clamping plate 21 to prevent the clamping plate 21 from rotating, which is convenient for the staff to use the clamping plate 21 to clamp and fix the measuring book. When the staff turns the threaded knob 20 to press the clamping plate 21 to clamp the measuring book, the clamping plate 21 drives the limit rod 25 to move backward, and the round block 26 pulls the second spring 27 to store force. When the staff releases the threaded knob 20 to press the clamping plate 21, the second spring 27 releases the force generated.The second spring 27 rebounds and pulls the round block 26 to push the limit rod 25 to drive the clamping plate 21 to move forward, opening the clamping of the clamping plate 21 on the measuring book, making it easier for the user to take out the measuring book.
