The stopper spring 1312 is compressed by pressing the sliding block 1311 in a radial direction of the telescopic bar 13. The two sliding blocks 1311 will move away from the limit springs 1312 under the urging of the limit springs 1312. The two sliding blocks 1311 are respectively embedded in the two sliding grooves 122 and can slide along the sliding grooves 122, so that the telescopic rod 13 and the second telescopic cylinder 12 can be slidably connected. When the sliding blocks 1311 slide along the sliding grooves 122 to the positioning holes 123, the two sliding blocks 1311 are inserted into the two positioning holes 123 respectively under the action of the limiting springs 1312, so that the telescopic rod 13 and the second telescopic cylinder 12 are fixedly connected. When the telescopic rod 13 needs to be retracted, the two sliding blocks 1311 need to be pressed and the telescopic rod 13 needs to be pushed in the axial direction, and the sliding blocks 1311 enter the sliding grooves 122 again to be unlocked.

The telescopic rod 13 is provided with three accommodating grooves 132, the accommodating grooves 132 are parallel to the axis of the telescopic rod 13, and the accommodating grooves 132 are communicated with the end part of the telescopic rod 13 far away from the limiting component 131. The end of the receiving groove 132 away from the limiting member 131 has a spherical groove 133. The receiving grooves 132 have three stopper sliding grooves 1331 therebetween adjacent to the spherical grooves 133, respectively.

As shown in fig. 14 and 15, the support assembly 30 includes three support feet 31 and three stoppers 32. The supporting legs 31 are cylinders, the end portions of the supporting legs 31 are provided with supporting leg connecting balls 311, the supporting leg connecting balls 311 are three, the supporting leg connecting balls 311 are respectively installed in the spherical grooves 133, the supporting legs 31 are rotatably connected with the telescopic rod 13, and the supporting legs 31 can be rotated to be embedded into the accommodating grooves 132. The three stoppers 32 are slidably mounted in the three stopper sliding grooves 1331, respectively, and the support leg 31 can be restricted by sliding the stoppers 32. After the supporting leg 31 is rotated out of the accommodating groove 132, the stopper 32 slides into the accommodating groove 132, so that the stopper 32 can limit the rotation of the supporting leg 31, and the supporting component 30 is opened. After the supporting leg 31 is inserted into the accommodating groove 132, the stopper 32 is slid into the accommodating groove 132, so that the supporting leg 31 is prevented from being rotated out of the accommodating groove 132, and the supporting member 30 is retracted.
