[0017] The utility model will be further explained in connection with specific embodiments. It should be understood that the following embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model.

[0018] Embodiment 1

[0019] Figure 1 It is a structural schematic view of the utility model.

[0020] As Figure 1 Indicated, a low strain sensor installation auxiliary handle includes: three-section telescopic rod body 100, universal joint adjusting assembly 200 and handle 300, universal joint adjusting assembly 200 is threadedly connected with the end of three-section telescopic rod body 100, handle 300 is arranged at the end of universal joint adjusting assembly 200.

[0021] Wherein, three-section telescopic rod body 100 includes: rod body 110, silica gel mounting groove 120, guide groove 130 and connecting flange 140, the both ends of the bottom of rod body 110 are equipped with connecting groove 111, connecting groove 111 is connected with silica gel mounting groove 120 and connecting flange 140 by bolt, sensor 1 is equipped in silica gel mounting groove 120, connecting flange 140 is connected with sensor 1 by bolt, guide groove 130 is arranged in rod body 110, one end of guide groove 130 is connected with silica gel mounting groove 120, the other end of guide groove 130 is connected with the top end of rod body 110, wire 2 is equipped in guide groove 130.

[0022] The gimbal adjusting assembly 200 adopts a ball hinge structure.

[0023] The purpose of the utility model is to design a new handle structure, put the sensor 1 and the wire 2 of the low strain sensor into the handle structure, and then use the telescopic handle.

[0024] Firstly, how to install. The rod body 110 in the three-section telescopic rod body 100 is a directly purchased existing structure, which adopts a three-section telescopic structure, and any rod body structure capable of realizing telescoping can realize the effect thereof. In the rod body 110, the inside is a hollow structure, a guide groove 130 is arranged in the hollow part and penetrates through the rod body 110, and the terminal end of the guide groove 130 is connected with the handle 300 through the gimbal adjusting assembly 200. When it is needed to use, the gimbal adjusting assembly 200 needs to be connected with the rod body 110 through screw threads, then the sensor 1 and the wire 2 connected with the sensor 1 are put into the rod body 110, then the wire 2 is in the recess 210, and then the gimbal adjusting assembly 200 is connected with the rod body 110. Fixation of the sensor 1: after the sensor enters the rod body 110, the sensor is placed in the silica gel mounting groove 120 through the center hole of the connecting flange 140, and then the sensor 1 is connected with the connecting flange 140, so that the fixation is completed.

[0025] Secondly, how to use.
