As shown in figures 1 to 4, the present invention is presented in pairs when in use, and the present embodiment is only exemplified by left-foot skate. The automatic telescopic adjustment climbing iron shoe comprises an L-shaped sliding rod 1, wherein the sliding rod 1 is formed by integrally forming a transverse rod 101 and a longitudinal rod 102, a lower baffle plate 2 is fixedly arranged on the transverse rod 101, a sliding sleeve 5 is arranged on the longitudinal rod 102, an upper baffle plate 3 is integrally welded on the sliding sleeve 5, the sliding sleeve 5 can slide up and down on the longitudinal rod 102, and anti-skid rubber pads 4 are arranged on the inner sides of the upper baffle plate 3 and the lower baffle plate 2; an upper fixing frame 6 and a lower fixing frame 7 are respectively welded at the upper end and the lower end of a longitudinal rod 102, a sliding sleeve 5 is positioned between the upper fixing frame 6 and the lower fixing frame 7, a hole is respectively formed in the upper fixing frame 6 and the lower fixing frame 7, a bearing is arranged in the hole, a nut 9 is welded on the sliding sleeve 5, in fact, a threaded plate is welded outside the sliding sleeve 5 or integrally manufactured, the two holes and the threaded hole in the nut 9 are coaxial, a lead screw 8 respectively penetrates through the holes in the upper fixing frame 6, the nut 9 and the lower fixing frame 7 and the nut 9, the lead screw can only rotate in a shaft mode, in the rotating process of the lead screw 8, the nut 9 drives the sliding sleeve 5 to vertically slide, the lower end of the lead screw 8 is fixedly connected with a motor 10 capable of rotating forwards and reversely, and the upper end of the lead screw 8.

The motor 10 is installed at the lower end of the longitudinal rod 102 by a support frame 12, the motor 10 is controlled by a 555 time-base timing circuit to operate, most of the 555 time-base timing circuit comprises a main switch K, IC1, an IC2 delay control circuit, manual switches K1 and K2, relays J1 and J2 for controlling the forward and reverse installation of the motor 10, all capacitors C1, C2, C3, C4, resistors R1, R2, R3, R4, diodes D1, D2, D3, D4 and the like are concentrated on a control box 13, and the control box 13 can be welded on the transverse rod 101.

A mounting plate 14 is welded on the transverse rod 101, a switch M of a 555 time-base timing circuit is mounted on the mounting plate 14, a movable touch rod 16 is mounted beside the switch M through a hinge shaft 15, the hinge shaft 15 is positioned at the upper position of the lower end of the movable touch rod 16, a thimble 17 is mounted at the lower end of the movable touch rod 16, and the thimble 17 faces to a closing sheet 18 on the switch; the lower end of the movable touch rod 16 is connected to one end of a return spring 19, and the other end of the return spring 19 is fixed to the mounting plate 14. The top end of the movable touch rod 16 is an inclined surface 20, and the inclined surface 20 faces the switch M; a limiting column 21 is welded on the mounting plate 14, and the limiting column 21 and the return spring 19 are respectively arranged at two sides of the movable touch rod 16.

The working process is as follows: before use, the main switch K is closed, the switch M is switched on at the moment, the switch M supplies power to the delay control circuit IC1, the delay control circuit IC1 works, the relay J1 supplies power to the motor 10, the motor 10 rotates in the positive direction, the lead screw 8 rotates simultaneously, and as the lead screw can only rotate in a shaft and cannot move axially, the nut 9 on the lead screw 8 and the sliding sleeve 5 drive the upper baffle 3 to move upwards to enlarge the distance between the upper baffle rod and the lower baffle rod, the delay control circuit IC1 stops working after supplying power for a certain time, the motor 10 stops working, and the distance between the upper baffle plate 3 and the lower baffle rod is temporarily fixed; then the motor 10 is switched on by adjusting the manual switches K1 and K2, so that the motor 10 rotates forwards and backwards to adjust the upper baffle 3 and the lower baffle rod to keep a proper distance, and then the rod can be climbed; in the climbing process, as shown in fig. 1, the movable touch rod 16 rotates rightwards under the squeezing action of the electric pole, the lower end of the movable touch rod 16 rotates rightwards, the thimble 17 abuts against the closing sheet 18, the switch M reaches another closing state, the switch M supplies power to the delay control circuit IC2, the delay control circuit IC2 works, a voltage opposite to that of the delay control circuit IC1 is supplied to the motor 10 through the relay J2, the motor 10 rotates in a paying-off direction opposite to the previous direction, the motor 10 rotates in the opposite direction, the distance between the upper blocking rod and the lower blocking rod is gradually shortened, so as to clamp the electric pole, after the delay control circuit IC2 works for a certain time (generally only a few seconds), the motor 10 stops working, at the moment, a person climbing the electric pole can step on the iron shoes, and the other foot climbs upwards. When a person who climbs the pole changes feet, the iron shoes leave the electric pole, the movable touch rod 16 is not bound, the iron shoes return to the initial state under the action of the return spring 19, the switch M returns to the initial connection state again, the delay control circuit IC1 works to slightly enlarge the distance between the upper stop rod and the lower stop rod, the enlarged distance is smaller than the distance which is just shortened, the steps are continuously repeated, namely the processes of the upper stop rod and the lower stop rod are carried out, the movable touch rod 16 and the switch M complete the switching work of the circuits when the left foot and the right foot of the person who climbs the pole alternate, the delay control circuit IC1 and the IC2 complete the power transmission work of the motor 10 within the set time, the motor 10 is protected, and the service life of the motor 10 is prolonged.

If the battery is not charged, the motor 10 cannot be started, the distance between the upper baffle and the lower baffle can be adjusted by manually rotating the handle, and the automatic adjustment cannot be realized at this moment.

In the control circuit, various electronic elements all adopt standard industrial grade, so that the circuit is stable and reliable, and the service life is ensured. The sliding rod 1, the sliding sleeve 5, the upper gear rod and the lower gear rod can be made of light-weight hard aviation aluminum materials, so that the weight can be greatly reduced, the load capacity and the safety of the iron shoe can be guaranteed, the motor 10 is a high-quality product with miniature variable speed and thermal protection, the screw rod and the nut 9 can be made of high-quality stainless steel, and the movable touch rod 16 can be made of high-quality elastic stainless steel sheets. Other accessories can be made of high-quality stainless steel products. But also all made of aviation aluminum.
