[0006] In order to achieve the above object, the present invention provides the following technical solutions: The cam is configured to move the first end of the second end of the second rod toward the support frame, and the second end of the second end of the second rod toward the support frame.

[0007] Preferably, the limiting mechanism includes a slide plate and a clamping block, the slide plate is slidably arranged inside the cavity, the two clamping blocks are fixedly arranged on one side of the slide plate close to the first rod body and the third rod body, one end of the two clamping blocks extends to the outside of the cavity, and the lower end of the first rod body and the upper end side walls of the third rod body are both provided with clamping grooves, and the two clamping blocks are clamped in the corresponding clamping grooves.

[0008] Preferably, sliding rods are fixedly provided on both sides of the cavity.

[0009] Preferably, a spring is movably sleeved on the rod wall of the sliding rod, and two ends of the spring are respectively fixedly connected to a side of the corresponding sliding plate away from the clamping block and an inner wall of the cavity.

[0010] Preferably, a push block is fixedly provided at the middle end of one side of the slide plate close to the clamping block, and one end of the push block extends to the outside of the cavity.

[0011] Preferably, the rod wall of the third rod body is coated with an anti-slip coating.

[0012] In the above technical solution, the technical effects and advantages provided by the present invention are: The present invention rotates the second rod body with the first rotating rod as the axis so that the second rod body and the first rod body are in a vertical state, and then rotates the third rod body with the second rotating rod as the axis so that the third rod body and the second rod body are in a vertical state. Then, a spring pushes the slide plate to move so that the two blocks are inserted into the corresponding slots, and the first rotating rod and the second rotating rod are limited, thereby completing the lengthening of the device and facilitating the measurement of distant and high positions.
