Detailed Description
The invention will be described in detail below with reference to the following figures and specific examples:
as shown in fig. 1-6, the walking stick comprises a hand-held part 1 and a stair railing clamping device 2 arranged at the bottom of the hand-held part 1. Wherein, handheld portion 1 includes the support column and sets up the walking stick head 3 at the support column top, and the support column includes two parallels, relative first bracing piece 4 and the second bracing piece 5 that sets up, and the top at first bracing piece 4 is installed to walking stick head 3.
The stair railing clamping device 2 comprises a torque conversion component and a clamping piece 6 arranged on the torque conversion component; the torsion conversion assembly comprises a mounting cavity 7 and a transmission block 8 arranged in the mounting cavity 7; the clamping piece 6 is L-shaped, one section of the clamping piece is arranged in the installation cavity 7 in a sliding mode along the axial direction of the supporting column and is in transmission connection with the transmission block 8, and the clamping piece 6 and the end portion of the installation cavity 7 form an adjustable clamping groove used for clamping the stair handrail.
The bottom of the first supporting rod 4 is fixedly arranged on the mounting cavity 7; the bottom of the second support rod 5 is rotatably installed in the installation cavity 7 and is rotatably connected with one end of the transmission block 8 to drive the clamping piece 6 to linearly move in the installation cavity 7.
Specifically, the bottom of second bracing piece 5 is passed through connecting seat 9 and is connected with the rotation of transmission piece 8, and connecting seat 9 includes connecting portion 10, sets up at the U-shaped seat 11 of connecting portion 10 one end and sets up connecting plate 12 at the connecting portion 10 other end, and the middle part of connecting portion 10 is passed through the round pin axle and is connected with the rotation of installation cavity 7, and the one end of transmission piece 8 is passed through the round pin axle and is rotated and install in U-shaped seat 11, and connecting plate 12 passes through the bolt and is connected with second bracing piece 5. Drive hole 13 has been seted up in the drive block 8, and holder 6 is connected with the drive of drive block 8 through connecting rod 14, and connecting rod 14 wears to establish in drive hole 13.
In order to ensure the stability of the operation of the clamping piece 6, a sliding groove 15 is arranged on the mounting cavity 7, and the clamping piece 6 slides along the sliding groove 15.
First bracing piece 4 and second bracing piece 5 are semi-circular post, and first bracing piece 4 top is provided with magnet 16 so that first bracing piece 4 and second bracing piece 5 attract mutually the laminating.
