Or, the bolt has a through hole, the stop member 160 is a bolt, and the bolt is screwed with the nut after passing through the through hole.

Fig. 3 is a schematic structural diagram of a rotating element in a pole embracing device according to an embodiment of the present invention, and referring to fig. 3, the rotating element 112 includes a second connecting portion 1122 and an arc portion 1123, the second connecting portion 1122 is connected to a first end of the pole embracing 120, the two rotating shafts 140 are located on two opposite sides of the second connecting portion 1122, and the arc portion 1123 is located at an end of the second connecting portion 1122.

The distance between the axis of the rotation shaft 140 and the bottom of the second connecting part 1122 and the distance between the axis of the rotation shaft 140 and the bottom of the base body 111 are equal, the distance between the axis of the rotation shaft 140 and the bottom of the second connecting part 1122 and the radius of the arc-shaped part 1123 are equal, and the central angle of the arc-shaped part 1123 is greater than or equal to 90 ° and less than or equal to 180 °.

When the holding pole 120 is in a vertical state, the bottom surface of the second connecting portion 1122 abuts against the top surface 200 of the emergency communication vehicle, when the holding pole 120 is in a horizontal state, the arc top of the arc-shaped portion 1123 is used for abutting against the top surface 200 of the emergency communication vehicle, and when the holding pole 120 rotates to the horizontal state in the vertical state, different arc surfaces of the arc-shaped portion 1123 are sequentially used for abutting against the top surface 200 of the emergency communication vehicle.

It can be understood that, by providing the rotating shaft 140 to hinge the rotating member 112 and the base body 111, the holding pole 120 is connected to the rotating member 112, and the arc-shaped portion 1123 of the rotating member 112 is always supported in contact with the top surface 200 of the emergency communication vehicle during the rotation of the holding pole 120, so that the rotating member 112 can reduce the burden of the rotating shaft 140. When the holding pole 120 is in the vertical state, the bottom plane of the second connecting portion 1122 of the rotating member 112 directly falls on the top surface 200 of the emergency communication vehicle, so that the stability of the holding pole 120 in the vertical state can be ensured.

Note that the central angle of the arc-shaped portion 1123 is greater than or equal to 90 ° and less than or equal to 180 °, and for example, the central angle of the arc-shaped portion 1123 may be 135 ° or 180 °.

The bearing seat 170 is provided with a bayonet 171, the bayonet 171 is matched with part of the outer side wall of the holding rod 120, and the holding rod 120 is abutted to the bayonet 171. Thus, when the holding pole 120 is in a horizontal state, the holding pole can be clamped in the clamping opening 171, and stability is improved.

With continued reference to fig. 1, in order to ensure that the pole 120 does not bounce when the emergency communication vehicle bumps, the pole assembly 100 further includes a fixing member 180, the fixing member 180 is used to connect with the top surface 200 of the emergency communication vehicle, and the fixing member 180 covers the pole 120 to fix the pole 120.

Specifically, the fixing member 180 may be located between the second end of the holding pole 120 and the supporting base 170. The fixing member 180 may be an elastic band, and both ends of the elastic band are located at both sides of the holding pole 120 and are respectively connected to the top surface 200 of the emergency communication vehicle. Therefore, when the elastic band is used, the elastic band can be sleeved on or separated from the holding pole 120 only by pulling the elastic band, and the operation is convenient.

Alternatively, the fixing member 180 is located between the base 110 and the supporting base 170. The fixing member 180 is a safety belt, one end of the safety belt is connected with the top surface 200 of the emergency communication vehicle, and an inserting piece arranged at the other end of the safety belt is connected with an inserting groove arranged on the top surface 200 of the emergency communication vehicle, so that the holding pole 120 is fixed.

It should be noted that, in order to ensure the fixing effect, the fixing member 180 may be located between the second end of the pole 120 and the support base 170 and between the base 110 and the support base 170, that is, the number of the fixing members 180 is multiple, for example, two or three, so as to improve the fixing effect of the pole 120.
