[0026] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figure 1-7 This embodiment provides a foot protection device for workers performing high-altitude work on ancient trees, comprising: a laceless shoe 1, with a protective block 2 at the bottom of the laceless shoe 1 and two fixing ropes 9 on the outside of the laceless shoe 1; a telescopic assembly located between the laceless shoe 1 and the protective block 2, the telescopic assembly comprising: a motor b6, a rotating cam 602, a short nail 701, a locking block 804, a motor a3, a cam 301, a hook 401, and a locking plate 502; and an installation assembly located on the outside of the laceless shoe 1, the installation assembly comprising: a limiting buckle a901, a strap 902, a limiting buckle b903, and a limiting buckle c904.

[0028] The protective block 2 has a memory foam 101 fixedly installed on its top and an anti-slip pattern on its bottom. A battery cavity 201 is opened on one side of the protective block 2, and a removable battery 202 is installed inside the battery cavity 201. A round tube 205 is fixedly connected to one side of the protective block 2, and a threaded cover 206 is provided on one side of the round tube 205. The outer side of the round tube 205 has an external thread, and the inside of the threaded cover 206 has an internal thread that matches the outer thread of the round tube 205. The round tube 205 and the threaded cover 206 are threadedly connected. The battery 202 can provide power to the device. When the battery 202 is depleted, the threaded cover 206 can be unscrewed from the round tube 205 to open the battery cavity 201, and then the battery 202 can be replaced. In addition, the anti-slip pattern can increase the friction between the protective block 2 and the ancient tree, and the memory foam 101 can improve the comfort of the wearer's heel.

[0029] A vibration sensor 203 is fixedly installed on one side of the protective block 2, and a microcontroller 204 is fixedly installed inside the protective block 2. A rotating cavity b601 is formed inside the protective block 2, and a motor b6 is fixedly installed inside the protective block 2. A rotating cam 602 is driven to one side of the motor b6 via a rotating shaft. A storage cavity 603 is formed at the bottom of the inner wall of the rotating cavity b601. A sliding fixing plate 7 is provided inside the storage cavity 603, and multiple short nails 701 are fixedly connected to the bottom of the fixing plate 7. Each short nail 701 is fitted with a return spring b702 on its outer side. The bottom of the inner wall of the storage cavity 603 has a slot b703 corresponding to the number of short nails 701. A spring cavity b805 is opened on one side of the inner wall of the storage cavity 603. A locking block 804 is provided inside the spring cavity b805. A positioning plate 802 is fixedly connected to one side of the locking block 804. A connecting rod 801 is fixedly connected to one end of the positioning plate 802. A spring b803 is fitted on the outer side of the connecting rod 801. A pull block 8 is fixedly connected to one end of the connecting rod 801.

[0030] When climbing an ancient tree, the user aligns the front of the laceless shoe 1 with the tree and then strikes it with their foot. This causes the vibration sensor 203 at the front of the laceless shoe 1 to vibrate, converting the physical vibration into an electrical signal. The electrical signal is then transmitted to the microcontroller 204. The microcontroller 204 receives the electrical signal from the vibration sensor 203 and calculates the number of impacts and the interval time using its integrated counter and timer to determine if three consecutive impacts have occurred. Based on this, the motor b6 is activated, causing the motor b6 to rotate and the rotating cam 602 to strike the fixing plate 7. This compresses multiple return springs b702, causing the bottom ends of multiple short nails 701 to extend out of the slots b703. At this time, the fixing plate 7 moves away from one side of the locking block 804, releasing the compressed springs b803 and pushing the locking block 804 above the fixing plate 7 to prevent the fixing plate 7 from resetting. This keeps the short nails 701 in the extended state, thus increasing the adhesion between the shoe and the ancient tree.

[0031] The protective block 2 has a rotating cavity a302 inside, and a motor a3 is fixedly installed inside the protective block 2. A cam 301 is driven to one side of the motor a3 via a rotating shaft. A contraction cavity 303 is opened at the bottom of the inner wall of the rotating cavity a302. A sliding mounting plate 4 is provided inside the contraction cavity 303. Multiple hooks 401 are fixedly installed at the bottom of the mounting plate 4. A return spring a402 is sleeved on the outside of each hook 401. A slot a403 corresponding to the number of hooks 401 is opened at the bottom of the inner wall of the contraction cavity 303. A spring cavity a505 is opened on one side of the inner wall of the contraction cavity 303. A retaining plate 502 is provided inside the spring cavity a505. A connecting block 503 is fixedly connected to one side of the retaining plate 502. A pull rod 501 is fixedly connected to one side of the connecting block 503. A spring a504 is sleeved on the outside of the pull rod 501. A pull plate 5 is fixedly connected to one side of the pull rod 501.

[0032] Since the timer integrated within the microcontroller 204 is essentially an incrementing or decrementing counter, it counts according to a set frequency. This frequency determines the step size of the counter's increment or decrement per unit time. By setting a preset count value, a specific time interval can be controlled. When the count value reaches this preset target value, the timer can trigger an interrupt or set a flag to indicate that the preset time has elapsed. Therefore, by using the timer integrated within the microcontroller 204, the user can strike the vibration sensor 203 three times within the preset time, causing the vibration sensor 203 to... An electrical signal is generated and transmitted to the microcontroller 204. The microcontroller 204 starts the motor a3, which rotates the cam 301 to strike the mounting plate 4, compressing multiple return springs a402. This causes the hook 401 to extend from the slot a403. At this time, the mounting plate 4 moves away from the side of the connecting block 503, and the compressed springs a504 are released. They push the connecting block 503 and the locking plate 502 to the top of the mounting plate 4, so that the hook 401 is in the extended state. Then it can cooperate with the short nail 701 to increase the adhesion between the shoe and the ancient tree.

[0033] After completing the work, the user can pull the pull plate 5, which will cause the clamping plate 502 and the connecting block 503 to compress the spring a504, so that the clamping plate 502 is removed from the top of the mounting plate 4. At this time, multiple reset springs a402 are released and push the mounting plate 4 upward, resetting the mounting plate 4 and multiple hooks 401. Similarly, when it is necessary to reset the short nail 701, the pull block 8 can be pulled, which will cause the positioning plate 802 and the clamping block 804 to compress the spring b803, so that the clamping block 804 is removed from the top of the fixing plate 7, thereby releasing the reset spring b702 and pushing the fixing plate 7 and the short nail 701 to reset.

[0034] Among them, the protective block 2 has two limit buckles c904 on one side, the shoe 1 without laces has two limit buckles a901 on both sides, the shoe 1 without laces has two limit buckles b903 on both sides, and the protective block 2 has straps 902 fixedly connected to both sides corresponding to the number of limit buckles b903.

[0035] In use, the user can place the laceless shoe 1 on top of the protective block 2, and pass multiple straps 902 through multiple limit buckles b903 respectively. Then, tie the corresponding straps 902 together in pairs. Then, pass two fixing ropes 9 through two limit buckles a901 and limit buckle c904 respectively, so that one end of the two fixing ropes 9 is between the two limit buckles c904. Then, tighten the two fixing ropes 9 and tie them together. At this time, the protective block 2 and the laceless shoe 1 can be bound together by the two fixing ropes 9 and multiple straps 902.

[0036] The working principle is as follows:

[0037] In use, the user can place the laceless shoe 1 on top of the protective block 2, and pass multiple straps 902 through multiple limit buckles b903 respectively. Then, tie the corresponding straps 902 together in pairs. Then, pass two fixing ropes 9 through two limit buckles a901 and limit buckle c904 respectively, so that one end of the two fixing ropes 9 is between the two limit buckles c904. Then, tighten the two fixing ropes 9 and tie them together. At this time, the protective block 2 and the laceless shoe 1 can be bound together by the two fixing ropes 9 and multiple straps 902.

[0038] When climbing an ancient tree, the user aligns the front of the laceless shoe 1 with the tree and then strikes it with their foot. This causes the vibration sensor 203 at the front of the laceless shoe 1 to vibrate, converting the physical vibration into an electrical signal. The electrical signal is then transmitted to the microcontroller 204. The microcontroller 204 receives the electrical signal from the vibration sensor 203 and calculates the number of impacts and the interval time using its integrated counter and timer to determine if three consecutive impacts have occurred. Based on this, the motor b6 is activated, causing the motor b6 to rotate and the rotating cam 602 to strike the fixing plate 7. This compresses multiple return springs b702, causing the bottom ends of multiple short nails 701 to extend out of the slots b703. At this time, the fixing plate 7 moves away from one side of the locking block 804, releasing the compressed springs b803 and pushing the locking block 804 above the fixing plate 7 to prevent the fixing plate 7 from resetting. This keeps the short nails 701 in the extended state, thus increasing the adhesion between the shoe and the ancient tree.

[0039] Furthermore, since the timer integrated within the microcontroller 204 is essentially an incrementing or decrementing counter, it counts according to a set frequency. This frequency determines the step size of the counter's increment or decrement per unit time. By setting a preset count value, control over a specific time interval can be achieved. When the count value reaches this preset target value, the timer can trigger an interrupt or set a flag to indicate that the preset time has elapsed. Therefore, through the timer integrated within the microcontroller 204, if the user strikes the vibration sensor 203 three times within the preset time, the vibration sensor 203 will... 03 generates an electrical signal again and transmits it to the microcontroller 204. The microcontroller 204 starts the motor a3. The motor a3 rotates the cam 301 to strike the mounting plate 4, which squeezes the multiple return springs a402, causing the hook 401 to extend from the slot a403. At this time, the mounting plate 4 moves away from the side of the connecting block 503, and the spring a504 in the compressed state is released, pushing the connecting block 503 and the locking plate 502 to the top of the mounting plate 4 so that the hook 401 is in the extended state. Then it can cooperate with the short nail 701 to increase the adhesion between the shoe and the ancient tree.

[0040] After completing the work, the user can pull the pull plate 5, which will cause the clamping plate 502 and the connecting block 503 to compress the spring a504, so that the clamping plate 502 is removed from the top of the mounting plate 4. At this time, multiple reset springs a402 are released and push the mounting plate 4 upward, resetting the mounting plate 4 and multiple hooks 401. Similarly, when it is necessary to reset the short nail 701, the pull block 8 can be pulled, which will cause the positioning plate 802 and the clamping block 804 to compress the spring b803, so that the clamping block 804 is removed from the top of the fixing plate 7, thereby releasing the reset spring b702 and pushing the fixing plate 7 and the short nail 701 to reset.
