When the auxiliary rod needs to be retracted, a user swings the swinging rods 603 on the left side and the right side outwards at the same time, the first spring 604 is compressed, the clamping wheel 605 is separated from the first clamping groove 601, then the hollow supporting tube 1 is pulled downwards, when the swinging supporting plates 2 on the left side and the right side are reset, the user loosens the swinging rods 603 on the left side and the right side, the swinging rods 603 swing inwards under the action of the elastic force of the first spring 604, and the clamping wheel 605 is clamped into the first clamping groove 601 on the lower side, so that the hollow supporting tube 1 and the sliding rod 4 are fixed together again.
When the ground for placing the auxiliary rod is uneven, a user can swing the supporting blocks 23 on the left side and the right side downwards, the second springs 24 are stretched, the supporting blocks 23 are in contact with the ground, and the supporting blocks 23 are stepped on by feet, so that the device is stably placed on the ground, the stability of the device during measurement can be improved, and the accuracy of the device during measurement is also improved. When the auxiliary rod is to be retracted, the user separates the foot from the support block 23 and swings upward to return under the elastic force of the second spring 24.
When the ground is uneven and the supporting block 23 needs to be used, a user swings the supporting block 23 downwards, when the supporting block 23 is located on the left side of the clamping block 29, under the action of the elastic force of the third spring 28, the clamping block 29 can be clamped into the third clamping groove 30, the supporting block 23 is slowly rotated downwards, the clamping block 29 can be sequentially clamped into the corresponding third clamping groove 30, the angle of the supporting block 23 can be fixed, and the supporting block 23 can be loosened after the adjustment is finished. When the supporting block 23 needs to be reset, a user moves the poke rod 27 outwards, the third spring 28 is compressed, the clamping block 29 is separated from the third clamping groove 30, the poke rod 27 is released after the supporting block 23 is reset, and the slide block 26 is reset under the elastic force of the third spring 28. Therefore, a user does not need to step on the supporting block 23 all the time by feet, and the use convenience is improved.
When the angle to be measured needs to be adjusted, a user firstly pushes the clamping rod 32 to move to the left, the fourth spring 33 is compressed, the supporting plate 20 can be rotated through the clamping rod 32 when the tail end of the clamping rod 32 is separated from the fourth clamping groove 34, so that the angle of the instrument fixing frame 21 is changed, after the angle adjustment is completed, the tail end of the clamping rod 32 is aligned with the corresponding fourth clamping groove 34, then the clamping rod 32 is released, the resetting is carried out under the elastic force of the fourth spring 33, and the tail end of the clamping rod 32 is clamped into the fourth clamping groove 34 again. Therefore, the instrument fixing frame 21 can be well fixed after the measurement angle is adjusted, the angle deviation caused by external force is prevented, and the measurement accuracy is improved.
