Description

Technical Field

[0001] This invention relates to the field of physical education teaching technology, and in particular to a teaching and demonstration device for physical education equipment. Background Technology

[0002] In physical education, sports equipment such as balls (e.g., basketballs, footballs), long objects (e.g., javelins, badminton racket shafts), and racket-shaped objects (e.g., tennis rackets, table tennis rackets) need to be arranged in an orderly manner and demonstrated through display devices to facilitate student observation and teacher explanation.

[0003] However, in practical applications, some problems remain unresolved. The following are some common issues with sports equipment teaching demonstration devices: First, poor equipment adaptability. Most devices have a single, fixed structure, failing to simultaneously meet the stable fixing needs of different types and sizes of sports equipment. Frequent adjustments or replacements of device components are required when changing equipment. Second, cumbersome operation. Traditional fixing methods rely on threads or single springs. When fixing equipment of different sizes, threads require multiple rotations to lock, and springs cannot adapt to significantly different equipment sizes, making quick fixing and unlocking difficult. Third, low space utilization. The fixed device structure prevents flexible adjustments to the display area layout based on the number of devices, easily leading to wasted space or overcrowded equipment placement. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0017] The beneficial effects of this invention are as follows: 1. Through the multifunctional limiting frame and elastic pressing structure, stable fixing of ball-shaped, long, and racket-shaped sports equipment can be achieved without replacing parts. It adapts to the differences in equipment of different sizes. The placement groove and circular groove of the limiting frame correspond to different types of equipment, and the spring and elastic sheet of the pressing component provide buffering to avoid equipment damage while ensuring fixing stability. It solves the limitation of traditional devices that are "one device for one purpose", meets the display needs of multiple types of equipment in sports teaching, and improves the versatility of the device.

[0018] 2. Through the linkage design of the driving component, positioning component and locking component, only two steps are required to fix the equipment: "move the handle and rotate slightly". To unlock, only the handle needs to be pulled. There is no need to rotate the thread multiple times or adjust the spring. This greatly shortens the fixing and unlocking time. Especially in classroom teaching, teachers can quickly change the display equipment, reduce the operation waiting time, and devote more energy to the explanation. At the same time, students can also observe the equipment changing and fixing process more clearly, which improves the interactivity and efficiency of teaching.

[0019] 3. The sliders 1 and 2 can slide flexibly along the frame. Combined with the positioning function of multiple sets of card holes, the number and spacing of the positioning mechanism can be flexibly adjusted according to the size of the teaching space and the number of equipment. When there are many equipment, the layout can be made denser, and when there are few, the spacing can be increased to avoid crowding. The layout can even be adjusted for a single type of equipment to adapt to different scenarios such as classrooms and training grounds. This solves the problem of fixed layout and low space utilization of traditional devices and improves the flexibility of use. Attached Figure Description

Detailed Implementation

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1, referring to Figures 1-5This is the first embodiment of the present invention. This embodiment provides a sports equipment teaching and display device, which includes a support mechanism 1 and a positioning mechanism 2.

[0042] Specifically, the support mechanism 1 includes a frame 11. The lower surface of the frame 11 has a locking hole 12, and the upper surface of the frame 11 has a locking hole 13. There are several locking holes 12 and 13, and the number of locking holes 12 and 13 is the same. The locking holes 12 and 13 are linearly arrayed on the frame 11. By setting the locking holes 12 and 13, the number of positioning mechanisms 2 installed on the frame 11 can be increased according to the number of sports equipment, so as to meet different usage needs and change the spatial layout. If there are many balls, the space can be arranged to place more balls. If there are many long javelins, the layout can be changed accordingly.

[0043] Specifically, the positioning mechanism 2 is installed on the frame 11 and includes a support component 21 and a pressing component 22 installed on the frame 11. The support component 21 cooperates with the first locking hole 12, and the pressing component 22 cooperates with the second locking hole 13. Limit frames 23 are fixed on both the support component 21 and the pressing component 22.

[0044] The support component 21 can be quickly installed on the frame 11 to support the lower limiting frame 23. The pressing component 22 can be quickly installed on the frame 11 to fix the upper limiting frame 23. When the pressing component 22 is operated, the bottom limiting frame 23 can be quickly moved down to limit and fix the sports equipment placed in the lower limiting frame 23. The corresponding positions of the support component 21 and the pressing component 22 are corresponding, and the sports equipment is fixed by the action of the two limiting frames 23 on them coming closer together. The structural design of the limiting frame 23 can meet the limiting and fixing of balls, long objects and rackets, meet different usage needs, and show the diversity of sports equipment teaching and display.

[0045] Specifically, the support component 21 includes a slider 211 that slides on the lower end of the frame 11. The slider 211 has a locking hole 212. A fixing member 213 is installed on the slider 211, and the fixing member 213 cooperates with the locking hole 12 and the locking hole 212 respectively. The pressing component 22 includes a slider 221 that slides on the upper end of the frame 11. The slider 221 has a locking hole 222. A limit member 223, a driving member 224 and a positioning member 225 are installed on the slider 221 respectively. The positioning member 225 cooperates with the locking hole 23 and the locking hole 222. The positioning member 225 cooperates with the driving member 224. A pressing member 226 is fixed at the lower end of the driving member 224. A locking member 227 is installed on the driving member 224. A handle 228 is fixed at the upper end of the driving member 224. The limit frame 23 is fixed at the upper end of the slider 211 and the lower end of the pressing member 226 respectively.

[0046] Both slider 1 211 and slider 2 221 have protrusions on both sides, so that slider 1 211 can slide on the frame 11 in a limited position on slider 2 221 and will not fall off. With the setting of fixing part 213 and locking hole 3 212, and with the cooperation of locking hole 1 12, after slider 1 211 is installed on the frame 11 and its position is adjusted, slider 1 211 can be fixed, thereby limiting the limiting frame 23 on the support component 21.

[0047] By setting the limiting member 223 and the four-hole 222, and with the cooperation of the two-hole 13, after the slider 221 is installed on the frame 11 and its position is adjusted, the slider 221 can be fixed, thereby determining the position of the driving member 224 and the pressing member 226, and thus limiting the limiting frame 23 at the lower end of the pressing component 22.

[0048] With the setting of the driving component 224 and the holding component 226, and with the cooperation of the locking component 227 and the positioning component 225, the upper limit frame 23 can be operated quickly. After manual up and down adjustment, the sports equipment can be fixed by simply rotating the handle 228. It is simple and convenient to operate when changing equipment with large size differences. It overcomes the problem that traditional fixing methods mostly use threads and springs. When fixing ball or rod-shaped sports equipment of different sizes with threads, many turns are required to lock the equipment due to the large size difference. When fixing with springs, the same specification of spring cannot stably fix equipment of different sizes.

[0049] By setting the holding member 226, when the driving member 224 moves up and down, it first contacts the tool and provides resistance. Then, as pressure is applied to the driving member 224, the positioning member 225 and the locking member 227 can position the driving member 224 after rapid adjustment. Then, the rotating handle 228 acts on the driving member 224, which in turn applies pressure to the holding member 226 again. The holding member 226 is then limited by the threaded locking method, so that the limiting frame 23 at the lower end of the holding member 226 fixes the sports equipment placed in the upper limit frame 23 of the support assembly 21.

[0050] With the locking component 227, the driving component 224 can be locked and unlocked quickly, making it convenient for physical education teachers to access the equipment and tools on the teaching demonstration device during explanations. When unlocking the sports equipment and tools, the handle 228 can be turned to operate the driving component 224 to move the holding component 226 upward, thereby moving the upper limit frame 23 upward to release the fixation of the sports equipment and tools.

[0051] Example 2, refer to Figures 2 to 12This is the second embodiment of the present invention, which is based on the previous embodiment.

[0052] Specifically, the limiting frame 23 includes a placement groove 231 formed thereon, a protrusion 232 provided on the limiting frame 23, and a circular groove 233 formed on the inner wall of the limiting frame 23. There are several placement grooves 231 and protrusions 232, which are distributed in a circumferential array on the limiting frame 23. The placement grooves 231 and protrusions 232 can cooperate with each other. By setting the placement groove 231, when fixing long rod-like equipment, it can be placed in the placement groove 231 on the lower limiting frame 23 to play a preliminary limiting role. Then, when the upper limiting frame 23 is pressed down, the protrusions 232 on it move into the placement groove 231 on the lower limiting frame 23 and make close contact with the long rod-like equipment for fixing.

[0053] The basic function of the limiting frame 23 is to fix ball-shaped equipment through its shape design. The circular groove 233 can provide support when fixing the end of racket-shaped equipment. The bottom of the circular groove 233 is set horizontally to ensure stability.

[0054] Specifically, the fixing component 213 includes an L-shaped plate 2131 fixed to the bottom of the slider 211, a U-shaped rod 2132 sliding on the L-shaped plate 2131, the two ends of the U-shaped rod 2132 cooperating with the first and third locking holes 212 respectively, a round block 2133 fixedly sleeved on both ends of the U-shaped rod 2132, and a spring 2134 movably sleeved on both ends of the U-shaped rod 2132, with the two ends of the spring 2134 fixed to the bottom of the round block 2133 and the surface of the L-shaped plate 2131 respectively.

[0055] The U-shaped rod 2132 passes through the L-shaped plate 2131 and slides therethrough. With the U-shaped rod 2132, when it is necessary to install the slider 211 on the frame 11 or adjust its position, the U-shaped rod 2132 is pulled to disengage its two ends from the first and third locking holes 212, causing the round block 2133 to move and the spring 2134 to compress. After the slider 211 is adjusted, the corresponding locking holes 12 and 3212 are aligned, and the U-shaped rod 2132 is released. Under the action of the spring 2134, the two ends of the U-shaped rod 2132 are inserted into the first and third locking holes 212 respectively, thereby limiting the position of the slider 211 and the limiting frame 23 on it.

[0056] Specifically, the limiting component 223 includes a round rod 2231 that slides on the second slider 221. The round rod 2231 passes through the second slider 221 and is slidably connected to it. There are four round rods 2231, which are distributed in a circumferential array on the second slider 221. A connecting plate 2232 is fixed to the upper end of the round rod 2231. A locking post 2233 is fixed to the bottom of both ends of the connecting plate 2232. The locking post 2233 cooperates with the locking hole 13 and the locking hole 222 respectively. A ring plate 2234 is fixed to the bottom of the round rod 2231. A spring piece 2235 is fixed between the top of the ring plate 2234 and the bottom of the second slider 221.

[0057] By setting the locking post 2233, when it is necessary to install the second slider 221 on the frame 11 or adjust its position, the ring plate 2234 is moved upward, thereby driving the round rod 2231 and the connecting plate 2232 to move upward, so that the locking post 2233 disengages from the locking hole 13 and the locking hole 222, and the spring piece 1 2235 deforms. After the position of the second slider 221 is adjusted, the corresponding locking hole 13 and the locking hole 222 are aligned, the ring plate 2234 is released, and under the action of the spring piece 1 2235, the locking post 2233 moves back and inserts into the locking hole 13 and the locking hole 222, thereby positioning the second slider 221 and the driving component 224 on it, corresponding to the support component 21 below.

[0058] Specifically, the driving component 224 includes a cylinder 2241 that slides on the slider 221, and the connecting plate 2232 and the ring plate 2234 are movably sleeved on the surface of the cylinder 2241. A groove 2242 is provided on the inner wall of the cylinder 2241, and a square plate 2243 slides in the groove 2242. A slot 2244 is provided on the surface of the cylinder 2241, and the slot 2244 is connected to the groove 2242. A guide hole 2245 is provided on the square plate 2243, and a stop block 2246 slides in the slot 2244. One end of the stop block 2246 extends into the inner cavity of the groove 2242 and is fixed with a guide post 2247. The guide post 2247 slides in the guide hole 2245. The positioning component 225 cooperates with the slot 2244 and the stop block 2246 respectively.

[0059] The cylinder 2241 passes through and slides through the slider 221. There are several slots 2244, guide holes 2245, guide posts 2247, and abutments 2246. The slots 2244 are linearly arrayed on both sides of the cylinder 2241, and the guide holes 2245 are linearly arrayed on the square plate 2243. Each guide hole 2245 is divided into three parts: the first and third parts prevent the abutments 2246 from moving when the guide posts 2247 move within them; the second part... When the guide post 2247 moves within it, it enables the abutment block 2246 to move. By setting the abutment block 2246, when it does not move within the slot 2244, it fills the slot 2244, preventing the positioning member 225 from positioning the cylinder 2241 and preventing it from moving further. This allows the cylinder 2241 to move smoothly on the slider 221 until the limiting frame 23 on the pressing member 226 at the lower end of the cylinder 2241 contacts and blocks the equipment.

[0060] Specifically, a connecting block 2248 slides on the inner wall of the cylinder 2241, and one side of the connecting block 2248 is fixed to the upper surface of the square plate 2243. A threaded sleeve 2249 is fixed to the other end of the connecting block 2248. A threaded tube 22410 is threadedly connected to the inner wall of the threaded sleeve 2249. A support plate 22411 is fixed to the inner wall of the cylinder 2241, and the support plate 22411 is sleeved on the surface of the threaded tube 22410. A spring 22412 is movably sleeved on the upper surface of the threaded tube 22410. The two ends of the second slider 22412 are respectively fixed to the lower end of the screw tube 22410 and the upper end of the support plate 22411. A limiting ring 22413 is fixedly sleeved on the surface of the screw tube 22410, and a stop ring 22414 is fixedly sleeved on the lower end surface of the cylinder 2241. A limiting groove 22415 is opened on the outer surface of the cylinder 2241. A limiting block 22416 is fixed on the second slider 221, and the limiting block 22416 slides in the limiting groove 22415. The screw tube 22410 cooperates with the pressing member 226.

[0061] The handle 228 is fixed to the upper end of the screw tube 22410. When the handle 228 moves the entire drive unit 224 downward, the limiting frame 23 at the lower end of the holding member 226 contacts the equipment placed in the limiting frame 23 below. The holding member 226 provides resistance. As the handle 228 applies pressure, the screw tube 22410 and the threaded sleeve 2249 move downward, thereby driving the connecting block 2248 to move downward. At this time, the spring 22412 is compressed. The downward movement of the connecting block 2248 causes the groove 2242 in the cylinder 2241 of the square plate 2243 to move. During this process, the locking member 227 locks and limits the connecting block 2248, preventing it from moving relative to the cylinder 2241.

[0062] Simultaneously, the guide post 2247 enters the third part from the first part of the guide hole 2245 through the second part, thereby causing the abutment 2246 to move within the slot 2244, exposing part of the slot 2244. Continued pressure is applied to move the cylinder 2241 up and down on the slider 221. When the slot 2244 aligns with the positioning member 225, the locking block 2252 on the positioning member 225 is inserted into the slot 2244, thereby positioning the cylinder 2241. Then, the handle 228 is slightly rotated to rotate and move the screw tube 22410 on the threaded sleeve 2249, thereby applying pressure to the holding member 226 and acting on the limiting frame 23, quickly fixing the equipment between the two limiting frames 23.

[0063] The limiting ring 22413 limits the screw tube 22410, ensuring that the threaded part of the screw tube 22410 is always located in the threaded groove part of the threaded sleeve 2249, ensuring that they are always in a threaded connection state. With the setting of the abutment ring 22414, when the operating drive 224 moves the cylinder 2241 on it upward, it can drive the abutment ring 22414 to move upward and contact the ring plate 2234, thereby causing the ring plate 2234, the round rod 2231, the connecting plate 2232 and the locking post 2233 to move upward, so that the locking post 2233 disengages from the locking hole 13 and the locking hole 222, releasing the fixation of the slider 221. With the setting of the limiting groove 22415 and the limiting block 22416, the cylinder 2241 is limited and guided, so that it can only move up and down on the slider 221 and will not rotate.

[0064] Specifically, the positioning component 225 includes a groove 2251 formed in the inner wall of the slider 221, a locking block 2252 sliding in the groove 2251, and the locking block 2252 cooperating with the slot 2244 and the abutment 2246 respectively. A spring 3 2253 is fixed between the inner wall of the groove 2251 and one end of the locking block 2252. A square groove 2254 is formed in the inner wall of the groove 2251. A square block 2255 is fixed at the bottom of the locking block 2252, and the square block 2255 slides in the square groove 2254. The square block 2255 and the square groove 2254 guide and limit the locking block 2252, so that it can move within a certain range and prevent the locking block 2252 from moving out of the groove 2251.

[0065] One end of the locking block 2252 is provided with a bevel. With this setting, after the abutment block 2246 moves in the slot 2244 and exposes part of the slot 2244, as the cylinder 2241 continues to move down, when the slot 2244 corresponds with the locking block 2252, the locking block 2252, under the action of the spring force of the third spring 2253, can easily insert the beveled end into the slot 2244, thereby positioning the cylinder 2241 on the second slider 221, so that it can no longer move. This facilitates the screw tube 22410 to apply pressure to the holding member 226 when the screw rotates. Furthermore, when the abutment block 2246 moves back to squeeze the locking block 2252 and resets the locking block 2252 during subsequent unlocking, it is convenient for the lifting handle 228 to move the cylinder 2241 up, so that the locking block 2252 can be more easily disengaged from the slot 2244.

[0066] Example 3, referring to Figures 2 to 16 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0067] Specifically, the holding member 226 includes a sliding rod 2261 that slides on the lower end of the cylinder 2241. Two sliding rods 2261 are provided at the lower end of the cylinder 2241. The sliding rods 2261 pass through the cylinder 2241 and are slidably connected to it. A pressure plate 2262 is fixed at the lower end of the sliding rod 2261, and the pressure plate 2262 cooperates with the screw tube 22410. A spring piece 2263 is fixed between the lower end of the cylinder 2241 and the top of the pressure plate 2262. A spline rod 2264 slides on the pressure plate 2262. A limiting frame 23 is fixed at the lower end of the spline rod 2264. A spring 2265 is movably sleeved on the surface of the spline rod 2264, and the two ends of the spring 2265 are respectively fixed to the bottom of the pressure plate 2262 and the surface of the limiting frame 23. An anti-detachment block 2266 is fixed at the upper end of the rod 2231, and an anti-detachment block 2267 is fixed at the upper end of the spline rod 2264.

[0068] With the setting of spring 2263 and spring 2265, as the holding member 226 moves down with the cylinder 2241, after the limiting frame 23 at its lower end contacts the equipment, the continued downward movement of the cylinder 2241 needs to overcome the elastic force of spring 2263 and spring 2265. During the process of overcoming the pressure, when the handle 228 continues to move down, it drives the screw tube 22410, threaded sleeve 2249 and connecting block 2248 to move inside the cylinder 2241. First, the threaded sleeve 2249 applies pressure to the spring 22412 to compress and deform it.

[0069] At the same time, the movement of the connecting block 2248 causes the square plate 2243 to move within the groove 2242, thereby causing the guide post 2247 to move within the guide hole 2245, and enabling the abutment block 2246 to move within the slot 2244, exposing part of the slot 2244, which facilitates the insertion of the positioning piece 225 to position the cylinder 2241 on the slider 221, preventing relative sliding. Then, by slightly rotating the handle 228, the screw tube 22410 rotates on the threaded sleeve 2249, causing the screw tube 22410 to move down and apply pressure to the pressure plate 2262, thereby causing the slide rod 2261 to move down. The pressure plate 2262 applies pressure to the spring 2265, causing it to continue to compress. The resulting elastic force acts on the upper limiting frame 23, thereby quickly fixing the equipment between the two limiting frames 23.

[0070] The spline rod 2264 passes through the pressure plate 2262 and is slidably connected to it. The spline rod 2264 guides and limits the lower limit frame 23 to prevent it from rotating. The anti-detachment block 2266 limits the round rod 2231 to prevent the sliding rod 2261 from detaching from the cylinder 2241. The anti-detachment block 2267 limits the spline rod 2264 to prevent it from detaching from the pressure plate 2262.

[0071] Specifically, the locking component 227 includes a locking rod 2271 that slides on the cylinder 2241, a locking hole 2272 on the connecting block 2248, and the locking rod 2271 and the locking hole 2272 cooperate. A handle 2273 is fixed to one end of the locking rod 2271 located outside the cylinder 2241. A spring piece 2274 is fixed between the surface of the handle 2273 and the surface of the cylinder 2241. A guide groove 2275 is provided inside the cylinder 2241. A guide block 2276 is fixed to the surface of the locking rod 2271, and the guide block 2276 slides in the guide groove 2275.

[0072] The locking rod 2271 passes through the cylinder 2241 and is slidably connected to it. One end of the locking rod 2271 is chamfered, and the lower end of the connecting block 2248 is provided with a bevel. With this setting, when the connecting block 2248 moves down together with the threaded sleeve 2249, the bevel of the connecting block 2248 contacts the chamfered end of the locking rod 2271 and squeezes it to move, thereby moving the handle 2273 and deforming the spring plate 2274. When one end of the locking rod 2271 is aligned with the locking hole 2272, under the action of the spring plate 2274, the locking rod 2271 is inserted into the locking hole 2272 to lock the connecting block 2248 and the screw tube 22410, thereby locking the square plate 2243 that moves together with the connecting block 2248, and thus positioning the abutment 2246 after the guide post 2247 moves after the guide hole 2245 drives it.

[0073] When it is necessary to release the limiting frame 23 from the limiting fixation of the instrument and equipment for replacement, the handle 2273 can be pulled to move the locking rod 2271 out of the locking hole 2272. Then, under the action of the spring 22412, the threaded sleeve 2249, the connecting block 2248 and the square plate 2243 are reset, so that the guide post 2247 moves from the third part of the guide hole 2245 through the second part to the first part, so that the abutment block 2246 moves to push one end of the locking block 2252 out of the slot 2244, thereby releasing the limitation on the cylinder 2241. The drive component 224 can be pulled up directly to move the holding component 226 and the limiting frame 23 up. Alternatively, the screw tube 22410 can be moved up by rotating the handle 228, thereby moving the holding component 226 and the limiting frame 23 up to release the limitation.

[0074] Specifically, a display 14 is provided on one side of the frame 11, and a support frame 15 is fixed at the bottom of the frame 11. The display 14 is mounted on the frame 11 through a two-degree-of-freedom robotic arm structure, which can realize pitch and left and right rotation adjustment and locking. This is existing technology. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0075] During use, the device is assembled and its space is adjusted as follows: The frame 11 of the support mechanism 1 provides basic support. According to the number and type of equipment, slide slider 1 211 to a suitable position on the frame 11, and fix slider 1 211 by inserting the U-shaped rod 2132 of the fixing member 213 into the first and third locking holes 12 and 322. Similarly, slide slider 221, and fix slider 221 by inserting the locking post 2233 of the limiting member 223 into the second and fourth locking holes 13 and 422. This completes the layout adjustment of the positioning mechanism 2 and ensures that the upper and lower limiting frames 23 correspond.

[0076] Equipment Placement and Initial Fixing: Place the sports equipment into the lower limiting frame 23. Balls are placed directly into the limiting frame 23, long items are placed into the placement slot 231, and racket-shaped items are placed into the round slot 233 at the end. Hold the handle 228 and push the cylinder 2241 of the driving component 224 downward. The limiting frame 23 of the holding component 226 first contacts the equipment and continues to apply pressure to overcome the elastic force of the second spring 2263 and the fourth spring 2265, causing the connecting block 2248 and the square plate 2243 to move downward. The guide post 2247 drives the abutment block 2246 to move and expose the slot hole 2244. The locking block 2252 of the positioning component 225 is inserted into the slot hole 2244, completing the initial positioning of the cylinder 2241.

[0077] Equipment locking and unlocking: Slightly rotate handle 228, the screw tube 22410 rotates and moves downward in the threaded sleeve 2249, squeezing the pressure plate 2262, the spring four 2265 is further compressed, and the upper limit frame 23 tightly abuts against the equipment to achieve locking; when changing equipment, pull handle 2273 to make the locking rod 2271 disengage from the locking hole 2272, the spring two 22412 rebounds and drives the connecting block 2248 to reset, the abutment block 2246 pushes the locking block 2252 out of the slot hole 2244, and lifting handle 228 drives the cylinder 2241 and the limit frame 23 to move upward to release the fixation.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
