Description

Technical Field

[0001] This invention relates to the field of landscape maintenance technology, specifically to a landscape maintenance device for landscape design. Background Technology

[0002] Garden design is the process of creating a beautiful natural environment and a space for living and recreation within a defined geographical area by using garden art and engineering techniques. This involves modifying the terrain (or further constructing hills, stacking rocks, and managing water features), planting trees and flowers, constructing buildings, and arranging garden paths. However, "three parts creation, seven parts maintenance"—high-cost garden landscapes, if lacking scientific and effective maintenance, will struggle to maintain their ideal state and are prone to problems such as grassland degradation, tree death, and overgrown weeds, leading to a rapid decline in landscape value. Therefore, promoting scientific and standardized maintenance management is a core element of the sustainable development of modern gardens.

[0003] With technological advancements, garden maintenance equipment has gradually become automated and intelligent. Existing maintenance facilities can integrate multiple functions such as automatic watering, fertilization, light regulation, and even wind protection, significantly improving plant growth quality and management efficiency through precise control. Among these methods, sprinkler irrigation is one of the most common and effective. To prevent and control pests and diseases or promote plant growth, maintenance personnel often need to add chemical pesticides or nutrients to the sprinkler water.

[0004] However, this type of design has a significant common drawback: after spraying, some droplets inevitably remain inside the nozzle, especially at the atomizing plate. This is particularly true when nutrients or pesticides are added to the spray water; the residual droplets can continue to corrode the metal components inside the nozzle, leading to rust, damage, and a shortened lifespan. Simultaneously, small impurities or crystallized pesticides in the water can easily clog the micropores of the atomizing plate, affecting the atomization effect for subsequent uses and even causing the nozzle to completely fail. Manual disassembly and cleaning are usually required, which increases maintenance costs and labor intensity, and is difficult to guarantee in a timely and thorough manner, still resulting in nozzle corrosion. Summary of the Invention

[0005] The purpose of this invention is to provide a landscape maintenance device for garden design that has a self-cleaning function and can effectively prevent nozzle corrosion and clogging. This device solves the technical problem that after spraying liquids containing nutrients or insecticides, residual droplets inside the nozzle and atomizing plate continuously corrode metal components and clog micropores, resulting in shortened equipment life, increased maintenance costs, and reduced maintenance effect.

[0006] To solve the above technical problems, the present invention adopts the following solution:

[0007] A landscape maintenance device for garden design includes a support mechanism, a blocking mechanism, and a limiting mechanism; the support mechanism includes a spraying component, a pressure applying component, an electric telescopic rod, a support component, and an infusion component; the blocking mechanism includes the blocking component and a squeezing component; the limiting mechanism includes a pressure component and a snap-fit ​​component; the spraying component includes a nozzle and an atomizing plate; the pressure applying component includes a fixed frame, a sliding blocking frame, a spring, and a pressure rod device; the squeezing component includes a fixed tube, a telescopic tube, a circular tube, and a ventilation device;

[0008] The upper end of the electric telescopic rod is fixedly connected to the infusion assembly, and the lower end is fixedly connected to the support assembly; one end of the nozzle is fixedly installed on one side of the infusion assembly, and the other end is connected to the atomizing plate; an installation groove is provided on the right side inside the nozzle; the sliding plugging bracket is slidably connected to the inner wall of the installation groove; the sealing assembly is fixedly installed on the left side inside the nozzle.

[0009] The fixing frame is fixedly installed in the middle of the nozzle; the pressure rod device passes through the fixing frame, with one end abutting against the sealing assembly and the other end fixedly connected to the sliding blocking frame; the spring is fixedly installed on the right side of the fixing frame and sleeved on the pressure rod device.

[0010] The upper end of the fixed tube passes through the nozzle and is connected to the ventilation device, while the lower end is connected to the telescopic tube; the upper end of the telescopic tube is fixedly connected to the nozzle, and the lower end is fixedly connected to the support assembly; the upper end of the circular tube passes through the support assembly and is connected to the telescopic tube.

[0011] The pressure assembly is located inside the nozzle and is fixedly connected to the venting device; the snap-fit ​​assembly is located inside the telescopic tube, with its upper end fixedly connected to the bottom end of the venting device and its lower end slidably connected to the inner wall of the circular tube. The infusion device is connected to an external water source or the solution to be sprayed, and the entire system is powered by an external power source.

[0012] In use, the device is installed in the location requiring maintenance using the support assembly. The electric telescopic rod extends, bringing the infusion device to its highest point. When the nozzle is at its highest point, the ventilation device and pressure assembly are sealed. The infusion device is then activated, allowing the solution to enter the nozzle. The pressure of the solution pushes the sliding plug against the inner wall of the mounting groove. The pressure rod opens the sealing assembly, allowing the solution to flow to the atomizing plate, where it is atomized and sprayed onto the plants. Simultaneously, the electric telescopic rod pushes the nozzle upwards, causing the nozzle to extend the telescopic tube, increasing its volume. This is achieved through the locking mechanism. The mechanism creates a negative pressure inside the telescopic tube and stores the water. After spraying, the electric telescopic rod retracts, the sealing component resets, and the latching component pushes the ventilation device to open. The negative pressure in the telescopic tube draws in air from the environment, drawing excess moisture from the atomizing plate to the left side of the nozzle and collecting it above the pressure component. At this point, the electric telescopic rod continues to retract, opening the pressure component and compressing the air inside the telescopic tube to create positive pressure, which is then pumped back into the nozzle, blowing the collected liquid out through the pressure component. When the electric telescopic rod returns to its lowest point, all mechanisms reset, preparing for the next operation.

[0013] Furthermore, the pressure rod device includes a sliding rod and a roller; the sliding rod passes through the first fixed frame and is slidably connected to the inner wall of the first fixed frame in the middle, rotatably connected to the roller at the left end, and fixedly connected to the sliding blocking frame at the right end; the first spring is located between the first fixed frame and the blocking frame and is sleeved on the sliding rod.

[0014] When pressurized water enters the nozzle from the transmission pipe, it generates a leftward thrust that drives the sliding blocker to move to the left, which in turn drives the sliding rod to move to the left, which in turn drives the roller to move to the left, squeezing the sealing assembly to open the flow channel and allowing the liquid to flow to the atomizing plate. When irrigation stops, the pressure decreases, causing the spring compressed by the sliding blocker to release its elasticity, pushing the sliding blocker and the entire pressure rod device to return to the right and close the flow channel.

[0015] Furthermore, the sealing assembly includes a second fixing frame, a first through-hole groove, a sliding plate, a tripod, and a second spring; the second fixing frame is fixedly installed inside the left side of the nozzle; the sliding plate is slidably installed inside the second fixing frame, and its bottom end is fixedly connected to the inner wall of the second fixing frame through the second spring; the first through-hole groove is formed on both sides of the second fixing frame; the sliding plate has a second through-hole groove that matches the first through-hole groove; one end of the tripod is fixedly installed on the sliding plate, and the other end extends out of the second fixing frame and contacts the roller.

[0016] When the roller moves to the left under the push of the sliding rod, it contacts and squeezes the inclined part of the tripod extending from the second fixed frame, pressing the sliding plate downward and compressing the spring, so that the second through-hole groove and the first through-hole groove opened on the side wall of the second fixed frame are aligned with each other, creating a connected channel, allowing the liquid in the nozzle to flow to the atomizing plate for atomization through the connected channel; when irrigation ends, the roller returns to its original position with the sliding rod and disengages from the tripod, the compressed second spring releases its elastic potential energy, pushes the sliding plate upward and resets, so that the second through-hole groove and the first through-hole groove are misaligned again, thereby closing the flow channel.

[0017] Furthermore, the ventilation device includes a sliding groove, a blocking block, and a through hole; the sliding groove is formed inside the nozzle; the bottom end of the blocking block extends into the fixing tube and is fixedly connected to the snap-fit ​​assembly, and the top end is connected to the pressure assembly; the through hole is formed at the lower end of the blocking block.

[0018] When the electric telescopic rod extends, the latching assembly fixed to the bottom of the blockage block pulls the blockage block into the sliding groove, keeping the ventilation device in a closed state. When the electric telescopic rod retracts, the latching assembly fixed to the bottom of the blockage block pushes the blockage block out of the sliding groove, causing the through hole to disengage from the sliding groove, opening the ventilation device, releasing the negative pressure stored in the telescopic tube, and drawing air from the natural environment through the holes in the atomizing plate, thereby removing residual moisture inside the atomizing plate.

[0019] Furthermore, the pressure assembly includes a connecting rod, a sliding blocking plate, and a second sliding groove; the second sliding groove is formed inside the nozzle near the atomizing plate; the sliding blocking plate is slidably connected to the second sliding groove; one end of the connecting rod is fixedly connected to the sliding blocking plate, and the other end is fixedly connected to the blocking block.

[0020] When the electric telescopic rod retracts, the latching assembly pushes the blocking block upwards within the sliding groove one, causing the connecting rod fixedly connected to the blocking block to move upwards simultaneously. This causes the sliding blocking plate to slide upwards along the inner wall of the sliding groove two inside the nozzle, creating a water outlet gap between the sliding blocking plate and the sliding groove two. After the water outlet gap appears, as the electric telescopic rod continues to retract, the internal space of the telescopic tube decreases, and the gas inside the telescopic tube will be transmitted to the nozzle through the through hole, blowing out residual water and impurities through the water outlet gap, effectively preventing solution residue.

[0021] Furthermore, the latching assembly includes a spring telescopic rod, a piston sealing plate, an inverted "L"-shaped rod, a compression spring, a sliding block, a rolling column, and a third spring; the top end of the spring telescopic rod is fixedly connected to the sealing block, and the top end is fixedly connected to the piston sealing plate; the piston sealing plate is slidably connected to the inner wall of the circular tube; one end of the third spring is fixedly connected to the inner wall of the circular tube, and the other end is fixedly connected to the middle of the rolling column; one end of the sliding block is rotatably connected to the rolling column; the inverted "L"-shaped rod is located inside the telescopic tube, and its lower end extends into the circular tube to abut against the sliding block; the upper end of the compression spring is fixedly connected to the inverted "L"-shaped rod, and its lower end is fixedly connected to the telescopic tube.

[0022] When the electric telescopic rod extends and pushes the nozzle upward, the piston sealing plate slides upward inside the circular tube under the action of the spring telescopic rod, acting as a piston. When the piston sealing plate rises to the position of the sliding block, it squeezes the sliding block, causing the spring to contract. When the piston sealing plate exceeds the sliding block, the sliding block jams the bottom edge of the piston sealing plate, preventing it from falling back under its own weight or internal negative pressure, thus storing the negative pressure inside the telescopic tube. When the electric telescopic rod retracts to its lowest point, the bottom of the fixed tube will press the inverted "L"-shaped rod, causing it to overcome the elastic force of the compressed spring and slide downward. The inclined surface at the lower end of the inverted "L"-shaped rod then pushes the sliding block, causing the sliding block to rotate relative to the corresponding rolling column, causing the sliding block to move away from the bottom of the piston sealing plate, releasing the latching restriction on the piston sealing plate. At this time, the elastic potential energy stored in the spring telescopic rod is released instantaneously, quickly pulling the piston sealing plate back into the depth of the circular tube.

[0023] Furthermore, the infusion assembly includes a storage tank and a transmission pipe; the upper end of the electric telescopic rod is fixedly connected to the bottom end of the storage tank; the left side of the storage tank is fixedly connected to the nozzle, and the right side is fixedly connected to the transmission pipe. When irrigation is required, the transmission pipe is equipped with an external water pump or gravity water supply system. When the external water pump or gravity water supply system is started, water flows through the transmission pipe fixedly connected to the right side of the storage tank and is transmitted to the storage tank for temporary storage. The storage tank acts as a pressure vessel; when the pressure reaches a certain level, the liquid, driven by the pressure, flows from the nozzle interface fixedly connected to its left side into the nozzle, providing a stable and continuous liquid source for subsequent atomized spraying.

[0024] Furthermore, the support assembly includes the support column and the fixed plate; the support column is fixedly installed at the bottom end of the fixed plate; the electric telescopic rod and the telescopic tube are fixedly installed at the top end of the fixed plate; the upper end of the circular tube passes through the fixed plate and is connected to the telescopic tube. The lower end of the support column is installed on the ground, and the upper end is firmly connected to the fixed plate, forming a rigid frame that provides stable support for the entire device.

[0025] The working principle of this invention is as follows:

[0026] In use, the device is installed at the location requiring maintenance via the support column. The electric telescopic rod extends, bringing the storage tank to its highest point. When the nozzle is at its highest point, the venting device and pressure components are sealed. The external water pump connected to the transmission pipe is turned on, allowing the solution to be temporarily stored inside the storage tank via the transmission pipe fixed to the right side of the tank. When the pressure inside the storage tank reaches a certain level, the pressure of the solution pushes the sliding block frame to the left against the inner wall of the mounting groove, thereby moving the sliding rod to the left. This, in turn, pushes the roller to the left, squeezing the inclined portion of the tripod extending from the second fixed frame, and pressing the sliding plate downwards. The compression spring aligns the through-hole slot two with the through-hole slot one on the side wall of the fixing frame two, creating a connecting channel. This allows the liquid in the nozzle to flow through the connecting channel to the atomizing plate for atomization and spraying onto the plants. As the electric telescopic rod pushes the nozzle upward, the piston sealing plate slides upward inside the round tube under the action of the spring telescopic rod, acting as a piston. When the piston sealing plate rises to the position of the sliding block, it squeezes the sliding block, causing the spring three to contract. When the piston sealing plate exceeds the sliding block, the sliding block jams the bottom edge of the piston sealing plate, preventing it from falling back under its own weight or internal negative pressure, thus storing the negative pressure inside the telescopic tube.

[0027] After spraying, the transmission pipe is closed, reducing the pressure and causing the compressed spring one to release its elasticity, pushing the sliding block holder and the entire pressure rod device to reset to the right. The roller, along with the sliding rod, resets and disengages from the tripod. The compressed spring two releases its elastic potential energy, pushing the sliding plate upwards to reset, causing the through-hole groove two to misalign with the through-hole groove one again, thus closing the flow channel. The electric telescopic rod retracts, and simultaneously, the spring telescopic rod of the snap-fit ​​assembly fixed to the bottom of the block pushes the block out of the sliding groove one, causing the through hole to disengage from the sliding groove one. This opens the ventilation device, releasing the negative pressure stored in the telescopic tube. Air from the environment is drawn through the holes in the atomizing plate, removing residual moisture inside the atomizing plate. The negative pressure in the telescopic tube draws in air from the environment, drawing excess moisture from the atomizing plate to the left side of the nozzle and collecting it above the pressure assembly. At this time, the electric telescopic rod continues to retract, and as the spring telescopic rod pushes the block upwards in the sliding groove one, it re-aligns with the block... The connecting rod of the fixed block also moves upward synchronously, thereby driving the sliding blocking plate to slide upward along the inner wall of the second groove opened inside the nozzle, so that a water outlet gap appears between the sliding blocking plate and the second groove. After the water outlet gap appears, as the electric telescopic rod continues to retract, the internal space of the telescopic tube decreases, and the gas inside the telescopic tube will be transmitted to the nozzle through the through hole, blowing out residual water and impurities through the water outlet gap, effectively avoiding solution residue. When the electric telescopic rod returns to the lowest point, the bottom of the fixed tube will press the inverted "L" shaped rod, causing it to overcome the elastic force of the compression spring and slide downward. The inclined surface at the lower end of the inverted "L" shaped rod then pushes the sliding block, causing the sliding block to rotate relative to the corresponding rolling column, causing the sliding block to move away from the bottom of the piston sealing plate, releasing the latch restriction on the piston sealing plate. At this time, the elastic potential energy stored in the spring telescopic rod is released instantly, quickly pulling the piston sealing plate back into the depth of the round tube, and all mechanisms reset, preparing for the next operation.

[0028] The beneficial effects of this invention are as follows:

[0029] This invention solves the problem of corrosion and clogging caused by residual chemical agents in traditional spray nozzles. Driven by the telescopic movement of an electric telescopic rod, the internal mechanism first draws in residual droplets from the surface of the atomizing plate, then uses high-pressure gas to completely blow out the collected material. This mechanically removes residual moisture and impurities from the atomizing plate and internal channels without manual intervention. This significantly extends the service life of the atomizing plate and nozzle channels, reduces maintenance costs, and ensures the uniformity and reliability of each spray, thus maintaining the health of garden plants and the aesthetic value of the landscape for a long time. Furthermore, all functions of this device are driven by a single electric telescopic rod and controlled by a purely mechanical structure, achieving a high degree of automation and significantly reducing the burden of manual operation. It is suitable for large-scale, refined modern garden maintenance scenarios. Attached Figure Description

Fixed connection; the spring 124 is fixedly installed on the right side of the fixed bracket 121 and sleeved on the pressure rod device; the upper end of the fixed tube 224 passes through the nozzle 111 and is connected to the ventilation device, and the lower end is connected to the telescopic tube 225; the upper end of the telescopic tube 225 is fixedly connected to the nozzle 111, and the lower end is fixedly connected to the support assembly; the upper end of the round tube 226 passes through the support assembly and is connected to the telescopic tube 225; the pressure assembly 31 is located inside the nozzle 111 and is fixedly connected to the ventilation device; the snap-fit ​​assembly 32 is located inside the telescopic tube 225, and the upper end is connected to the ventilation device.

[0047] The working principle of this embodiment is as follows:

[0048] The following section adds the serial numbers to the text and corrects any possible errors:

[0049] In use, the device is installed at the location requiring maintenance via the support column 13. The storage tank 16 is connected to the transmission pipe 17. The power is turned on, and the electric telescopic rod 15 is extended to bring the storage tank 16 to its highest point, i.e., when the nozzle 111 is at its highest point. At this point, the ventilation device and pressure component 31 are in a sealed state. The external water pump connected to the transmission pipe 17 is turned on, allowing the solution to be transported through the transmission pipe 17 fixedly connected to the right side of the storage tank 16 to the inside of the storage tank 16 for temporary storage. When the pressure inside the storage tank 16 reaches a certain level, the pressure of the solution pushes the sliding blocking frame 123 to slide against the inner wall of the mounting groove 113. The pressure rod device opens the sealing component 21, allowing the solution to flow to the atomizing plate 112, where it is atomized and sprayed onto the plants. The electric telescopic rod 15 pushes the nozzle 111... As the nozzle 111 rises, it drives the telescopic tube 225 to extend, increasing the volume inside the tube. The locking assembly 32 creates a negative pressure inside the tube 225, storing the liquid. After spraying, the electric telescopic rod 15 retracts, the sealing assembly 21 resets, and the locking assembly 32 opens the ventilation device. The negative pressure in the telescopic tube 225 draws in air from the environment, drawing excess moisture from the atomizing plate 112 to the left side of the nozzle 111 and collecting it above the pressure assembly 31. The electric telescopic rod 15 then continues to retract, opening the pressure assembly 31 and compressing the air inside the tube 225 to create positive pressure, which is then pumped back into the nozzle 111, blowing the collected liquid out through the pressure assembly 31. When the electric telescopic rod 15 returns to its lowest point, all mechanisms reset, preparing for the next operation.

[0050] Example 2

[0051] The difference from Embodiment 1 is that the pressure rod device includes a sliding rod 122 and a roller 126; the sliding rod 122 passes through the first fixing frame 121, and its middle part is slidably connected to the inner wall of the first fixing frame 121, its left end is rotatably connected to the roller 126, and its right end is fixedly connected to the sliding blocking frame 123; the first spring 124 is located between the first fixing frame 121 and the blocking frame 123, and is sleeved on the sliding rod 122; the blocking assembly 21 includes a second fixing frame 211, a through hole groove 212, a sliding plate 213, a tripod 215, and a second spring. 216; The second fixing bracket 211 is fixedly installed inside the left side of the nozzle 111; the sliding plate 213 is slidably installed inside the second fixing bracket 211, and its bottom end is fixedly connected to the inner wall of the second fixing bracket 211 through the second spring 216; the first through hole groove 212 is opened on both sides of the second fixing bracket 211; the sliding plate 213 is provided with a second through hole groove 214 that matches the first through hole groove 212; one end of the tripod 215 is fixedly installed on the sliding plate 213, and the other end extends out of the second fixing bracket 211 and contacts the roller 126.

[0052] When pressurized water flows into the nozzle 111 from the transmission pipe 17, it generates a leftward thrust, driving the sliding block bracket 123 to move to the left. This, in turn, drives the sliding rod 122 to move to the left, which in turn drives the roller 126 to move to the left. When the roller 126 moves to the left under the push of the sliding rod 122, it contacts and squeezes the inclined part of the tripod 215 extending out of the fixed bracket 211, pressing the sliding plate 213 to slide downward, compressing the spring 124, and causing the through-hole groove 214 to contact the through-hole groove 2 on the side wall of the fixed bracket 211. The nozzles 111 and 12 are aligned to form a connected channel, allowing the liquid in the nozzle 111 to flow through the connected channel to the atomizing plate 112 for atomization. When irrigation ends, the pressure decreases, causing the compressed spring 124 to release its elasticity, pushing the sliding block frame 123 and the entire pressure rod device to reset to the right. The roller 126 resets with the sliding rod 122 and disengages from the tripod 215. The compressed spring 216 releases its elastic potential energy, pushing the sliding plate 213 to slide upwards and reset, causing the through-hole groove 214 to misalign with the through-hole groove 212 again, thereby closing the flow channel.

[0053] The working principle of this embodiment is the same as that of Embodiment 1.

[0054] Example 3

[0055] The difference from Embodiment 2 is that the ventilation device includes a sliding groove 221, a blocking block 222, and a through hole 223; the sliding groove 221 is formed inside the nozzle 111; the bottom end of the blocking block 222 extends into the fixing tube 224 and is fixedly connected to the snap-fit ​​assembly 32, and the top end is connected to the pressure assembly 31; the through hole 223 is formed at the lower end of the blocking block 222; the pressure assembly 31 includes a connecting rod 311, a sliding blocking plate 312, and a second sliding groove 313; the second sliding groove 313 is formed inside the nozzle 111 near the atomizing plate 112; the sliding blocking plate 312 is slidably connected to the second sliding groove 313; one end of the connecting rod 311 is fixedly connected to the sliding blocking plate 312, and the other end is fixedly connected to the blocking block 222; the snap-fit ​​assembly 32 includes a spring telescopic rod 3 21. Piston sealing plate 322, inverted "L"-shaped rod 323, compression spring 324, sliding block 325, rolling column 326, and spring 327; the top end of the spring telescopic rod 321 is fixedly connected to the blocking block 222, and the top end is fixedly connected to the piston sealing plate 322; the piston sealing plate 322 is slidably connected to the inner wall of the round tube 226; one end of the spring 327 is fixedly connected to the inner wall of the round tube 226, and the other end is fixedly connected to the middle of the rolling column 326; one end of the sliding block 325 is rotatably connected to the rolling column 326; the inverted "L"-shaped rod 323 is located inside the telescopic tube 225, and the lower end extends into the round tube 226 to abut against the sliding block 325; the upper end of the compression spring 324 is fixedly connected to the inverted "L"-shaped rod 323, and the lower end is fixedly connected to the telescopic tube 225.

[0056] When the electric telescopic rod 15 extends, pushing the nozzle 111 upward, the piston sealing plate 322, driven by the spring telescopic rod 321, slides upward within the circular tube 226, acting as a piston. When the piston sealing plate 322 rises to the position of the sliding block 325, it squeezes the sliding block 325, causing the spring 327 to contract. When the piston sealing plate 322 exceeds the sliding block 325, the sliding block 325 locks the bottom edge of the piston sealing plate 322, preventing it from falling back under its own weight or internal negative pressure, thus storing the negative pressure within the telescopic tube 225 and simultaneously fixing it in place. The spring telescopic rod 321 connected to the bottom of the blockage block 222 pulls the blockage block 222 to fix it in the sliding groove 221, keeping the ventilation device in a closed state. When the electric telescopic rod 15 retracts, the spring telescopic rod 321 fixed to the bottom of the blockage block 222 pushes the blockage block 222 out of the sliding groove 221, causing the through hole 223 to disengage from the sliding groove 221, opening the ventilation device, releasing the negative pressure stored in the telescopic tube 225, and drawing air from the natural environment through the holes of the atomizing plate 112. The spring telescopic rod 321 pushes the blockage block 222 in the sliding groove 221. When the sliding block 221 slides upward, the connecting rod 311, which is fixedly connected to the block block 222, also moves upward synchronously. This causes the sliding block plate 312 to slide upward along the inner wall of the sliding groove 313 inside the nozzle 111, creating a water outlet gap between the sliding block plate 312 and the sliding groove 313. As the electric telescopic rod 15 continues to retract, the internal space of the telescopic tube 225 decreases, and the gas inside the telescopic tube 225 is transmitted to the nozzle 111 through the through hole 223, blowing out residual water and impurities through the water outlet gap, effectively preventing... When the electric telescopic rod 15 retracts to its lowest point, the bottom of the fixed tube 224 will press the inverted "L"-shaped rod 323, causing it to slide downwards against the elastic force of the compressed spring 324. The inclined surface at the lower end of the inverted "L"-shaped rod 323 will then push the sliding block 325, causing the sliding block 325 to rotate relative to the corresponding rolling column 326. This will cause the sliding block 325 to move away from the bottom of the piston sealing plate 322, releasing the latching restriction on the piston sealing plate 322. At this time, the elastic potential energy stored in the spring telescopic rod 321 will be released instantly, quickly pulling the piston sealing plate 322 back into the depth of the round tube 226.
