Description

Technical Field

[0001] The invention relates to the technical field of sculpture auxiliary devices, in particular to a rotary placing table for carving fine art artworks. Background Art

[0002] Sculpture is a kind of plastic arts, which refers to ornamental objects and memorial objects that are carved and shaped for beautification or commemoration, and have certain morals, symbols or pictographic shapes.

[0003] In the process of sculpture, it is usually necessary to use a rotating table to fix the sculpture material on the rotating table. When carving, the sculpture material is rotated to the position required by the sculptor to avoid frequent movement of the sculptor or the work position and unnecessary twisting movements, so as to observe the shape and proportion of the work more comprehensively. The sculptor does not need to move the body or adjust the posture frequently, which reduces the physical fatigue caused by long-term carving. It can easily show all angles of the work, allowing students to understand the carving process more clearly.

[0004] Existing rotating placement tables can usually only achieve height adjustment and horizontal rotation. For some larger sculptures, the sculptor still needs to move or even raise himself to complete the carving at some angles, which makes it difficult for the sculptor to maintain a relaxed carving state for a long time. At the same time, it is difficult to display the details of some larger-sized sculptures only by height adjustment and horizontal rotation. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a rotating placement table for carving fine art works. By adjusting the liquid pressure and flow direction inside the water tank, the height, rotation direction and rotation angle of the hollow rotating table can be adjusted and braked, so that the sculptor can reduce his own movement and the carved materials can be displayed at more angles.

DETAILED DESCRIPTION

[0047] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0048] like Figures 1 to 15 As shown, an embodiment of the present invention provides a rotating placement table for art artwork engraving, including a base 101, and a hollow rotating table 102 is arranged above the base 101, including:

[0049] The water tank 409 is used to store liquid to increase the overall weight of the device, and to adjust the height, horizontal rotation and rotation around one of the horizontal axes of the position of the hollow rotating table 102 by changing the liquid pressure inside the water tank 409;

[0050] The pedal 208 is used for the user to adjust the liquid pressure inside the water tank 409 by stepping on it;

[0051] The gear adjustment block 301 is used to adjust the flow direction of the liquid inside the water storage tank 409, thereby changing the movement mode of the hollow rotating platform 102;

[0052] The water storage chamber 407 is used to replenish the liquid in the water storage tank 409 when adjusting the height of the hollow rotating platform 102, so as to maintain the hydraulic pressure change in the water storage tank 409 stable when the pedal 208 is stepped on;

[0053] The first limiting tooth block 214 and the second limiting tooth block 215 are used to constrain or release the movement of the hollow rotating table 102 around its axial direction by combining or separating the first limiting tooth block 214 and the second limiting tooth block 215;

[0054] The second teeth 303 and the third teeth 319 are used to constrain or release the axial movement of the rotating plug 302 disposed inside the gear adjustment block 301 by combining or separating the second teeth 303 and the third teeth 319 .

[0055] In the embodiment of the present invention, before the engraving work is performed, the engraving material is first fixed on the surface of the hollow rotating table 102, and the height of the hollow rotating table 102 is adjusted to a suitable position by adjusting the gear adjustment block 301 and the water storage tank 409. During the engraving process, the first limit tooth block 214 and the second limit tooth block 215 are separated by adjusting the gear adjustment block 301 and the water storage tank 409, so that the hollow rotating table 102 can rotate horizontally around its central axis until the engraving material is rotated to a suitable position. Afterwards, the first limiting tooth block 214 is combined with the second limiting tooth block 215, so that the hollow rotating table 102 cannot continue to rotate around its central axis, and the second teeth 303 and the third teeth 319 are separated by adjusting the gear adjustment block 301 and the water tank 409, so that the hollow rotating table 102 can rotate around one of the horizontal axes until the engraving material is rotated to a suitable position, so that the second teeth 303 and the third teeth 319 are combined, and at this time the hollow rotating table 102 cannot continue to rotate around the horizontal axis.

[0056] A support sleeve 201 is fixedly connected to the surface of the base 101, and a lifting column 202 is slidably connected inside the support sleeve 201. A plurality of first constraint rods 203 are fixedly connected inside the support sleeve 201. The first constraint rods 203 are slidably connected to the lifting column 202 through a first sliding groove provided on the bottom surface of the lifting column 202. A sealing plug 204 is fixedly connected inside the support sleeve 201. The sealing plug 204 is slidably connected in a first through groove provided on the bottom surface of the lifting column 202. A U-shaped connecting platform 205 is fixedly connected to the upper surface of the lifting column 202. A bearing platform 206 is provided inside the U-shaped connecting platform 205. A mounting round box 207 is fixedly connected to the upper surface of the bearing platform 206. The hollow rotating table 102 is rotatably connected to the inside of the mounting round box 207 through a first bearing.

[0057] In the embodiment of the present invention, during the height adjustment of the hollow rotating platform 102, the liquid in the water storage tank 409 flows into the first through groove on the bottom surface of the lifting column 202, so that the lifting column 202, the first restraining rod 203, the sealing plug 204 and the supporting sleeve 201 slide relative to each other, and then the lifting column 202 drives the U-shaped connecting platform 205, the installation round box 207 and the hollow rotating platform 102 to move upward;

[0058] The hollow rotating platform 102 is moved downward by allowing the liquid in the first through groove opened on the bottom surface of the lifting column 202 to flow into the water storage tank 409 .

[0059] The surface of the supporting platform 206 is symmetrically fixedly connected with rotating cylindrical blocks 216, and the rotating cylindrical blocks 216 are all rotatably connected in the first circular groove opened on the surface of the U-shaped connecting platform 205. The second limiting tooth block 215 is fixedly connected to the inner bottom surface of the hollow rotating platform 102. An adjusting cavity 416 is opened inside the supporting platform 206. A rectangular slider 417 is arranged inside the adjusting cavity 416. A sixth spring 418 is arranged inside the adjusting cavity 416. The two ends of the sixth spring 418 are respectively fixedly connected to the U-shaped connecting platform 205 and the rectangular slider 417. The rectangular slider 417 is slidably connected to the supporting platform 206 through the rectangular part of the adjusting cavity 416. The rectangular slider 417 is fixedly connected to the first limiting tooth block 214, and the first limiting tooth block 214 and the second limiting tooth block 215 are meshingly connected.

[0060] In the embodiment of the present invention, by allowing the liquid inside the water tank 409 to flow into the regulating chamber 416, the rectangular slider 417 overcomes the elastic potential energy of the sixth spring 418 inside the first one-way valve 406 and moves in a direction away from the rotating cylindrical block 216 until the first limit tooth block 214 at the top of the rectangular slider 417 is separated from the second limit tooth block 215. At this time, the hollow rotating table 102 can rotate around its central axis inside the mounting circular box 207. When the hollow rotating table 102 is rotated to a suitable position, the rectangular slider 417 is reset by allowing the liquid inside the regulating chamber 416 to flow toward the water tank 409, that is, the first limit tooth block 214 is meshed with the second limit tooth block 215. At this time, the hollow rotating table 102 is constrained by the second limit tooth block 215 and the first limit tooth block 214 and cannot rotate around the central axis of the hollow rotating table 102.

[0061] A cylindrical cavity 220 is provided inside the U-shaped connecting platform 205, and the rotating cylindrical block 216 located on the left side is located inside the cylindrical cavity 220. A friction block 218, a second constraint rod 219 and a first screw rod 221 are provided inside the cylindrical cavity 220. The friction block 218 conflicts with the rotating cylindrical block 216 located on the left side. The second constraint rods 219 are respectively slidably connected to the second sliding grooves provided in a ring array on the surface of the friction block 218. The second constraint rods 219 are fixedly connected to the U-shaped connecting platform 205. The first screw rod 221 is threadedly connected to the first threaded hole provided on the inner wall of the cylindrical cavity 220. The end of the first screw rod 221 is fixedly connected to an L-shaped handle 222. The inside of the friction block 218 is fixedly connected to the second spring rod 223, and the telescopic end of the second spring rod 223 conflicts with the first screw rod 221.

[0062] In the embodiment of the present invention, when the hollow rotating table 102 is rotated and adjusted along one of the horizontal axis directions, the horizontal axis direction is the central axis direction of the rotating cylindrical block 216. In order to prevent the hollow rotating table 102 from rotating too fast around the central axis of the rotating cylindrical block 216 due to the excessive weight of the engraving material fixed on the surface of the hollow rotating table 102, thereby easily causing damage to the engraver, the first screw rod 221 can be rotated by the L-shaped handle 222, so that the second spring rod 223 inside the friction block 218 is compressed under the pressure of the first screw rod 221, thereby causing the friction block 218 to rotate too fast. 8 The squeezing force on the rotating cylindrical block 216 on the left side becomes larger, and the second constraint rod 219 prevents the friction block 218 from rotating around its central axis, thereby maintaining a stable positive pressure on the rotating cylindrical block 216. The compression of the second spring rod 223 increases the friction force of the friction block 218 on the rotating cylindrical block 216 on the left side, so that when the supporting platform 206 rotates, the user can actively rotate the hollow rotating table 102 to a suitable position, thereby preventing the hollow rotating table 102 from being actively rotated due to gravity, reducing the user's usage burden and increasing the safety of the device.

[0063] A plurality of first teeth 217 are fixedly connected to the surface of the rotating cylindrical block 216 on the left side in an annular array, a second rectangular sleeve 412 is fixedly connected to the first mounting groove opened on the inner wall of the cylindrical cavity 220, an adjusting tube body 413 is fixedly connected to the second through groove opened on the inner bottom surface of the second rectangular sleeve 412, a third rectangular sleeve 415 is slidably connected to the rectangular opening opened on the surface of the second rectangular sleeve 412, the third rectangular sleeve 415 is meshed with the first teeth 217 through a toothed protrusion arranged on the top, the adjusting tube body 413 is slidably connected to the inside of the third rectangular sleeve 415, a plurality of fifth springs 414 are arranged in an annular array inside the third rectangular sleeve 415, and both ends of the fifth spring 414 are fixedly connected to the third rectangular sleeve 415 and the adjusting tube body 413, respectively.

[0064] In the embodiment of the present invention, by making the liquid inside the water tank 409 flow to the inside of the regulating tube body 413, the third rectangular sleeve 415 moves in the direction away from the rectangular slider 417. During this process, the fifth spring 414 is stretched. When the hollow rotating table 102 is rotated to a suitable position, the liquid inside the regulating tube body 413 flows to the inside of the water tank 409, and the third rectangular sleeve 415 moves in the direction close to the rectangular slider 417 until the toothed protrusion on the top of the third rectangular sleeve 415 engages with the corresponding rectangular slider 417. At this time, the hollow rotating table 102 cannot rotate along the central axis direction of the rotating cylindrical block 216.

[0065] The gear adjustment block 301 is fixedly connected to the surface of the U-shaped connecting platform 205, and the gear adjustment block 301 is rotatably connected in the cylindrical T-shaped groove opened on the surface of the gear adjustment block 301. A first connecting hole 411 is opened on the surface of the gear adjustment block 301, and a first L-shaped groove 312 is opened on the surface of the rotating plug block 302, and the first L-shaped groove 312 is connected to the inside of the first connecting hole 411. Four second L-shaped grooves 320 are opened on the surface of the gear adjustment block 301, and the second L-shaped grooves 320 are all connected to the cylindrical T-shaped grooves opened on the surface of the gear adjustment block 301. A Z-shaped handle 313 is fixedly connected to the surface of the rotating plug block 302.

[0066] In the embodiment of the present invention, when the position of the hollow rotating table 102 is adjusted, the rotating plug block 302 is connected to the interior of the water tank 409 through the first L-shaped groove 312, the first connecting hole 411 and the first connecting hose 410. By rotating the rotating plug block 302, the first L-shaped groove 312 is connected to the interior of the corresponding second L-shaped groove 320, thereby adjusting the flow direction of the liquid inside the water tank 409, so that the height or horizontal rotation position of the hollow rotating table 102 or the rotation position along the central axis of the rotating cylindrical block 216 is adjusted.

[0067] An annular groove 304 is provided on the surface of the gear adjustment block 301, and a sliding cover body 306 is arranged inside the annular groove 304. The sliding cover body 306 is slidably connected to the gear adjustment block 301 through the annular groove 304. A plurality of columnar slide grooves 305 are provided on the surface of the gear adjustment block 301 in an annular array. Columnar connecting blocks 307 are slidably connected inside the columnar slide grooves 305. The columnar connecting blocks 307 are fixedly connected to the sliding cover body 306. A third spring 308 is provided inside the columnar slide grooves 305. The two ends of the third spring 308 are respectively fixedly connected to the gear adjustment block 301 and the sliding cover body 306. The second teeth 303 are fixedly connected to the surface of the rotating plug block 302 in an annular array. The third teeth 319 are fixedly connected to the inner wall of the sliding cover body 306 in an annular array. The third teeth 319 are meshed with the second teeth 303.

[0068] In the embodiment of the present invention, the liquid flow directions corresponding to the four second L-shaped grooves 320 are named as the height raising gear, the horizontal rotation gear, the vertical rotation gear and the height lowering gear respectively. When adjusting the gear, the sliding cover body 306 is moved in the direction away from the gear adjusting block 301 until the third tooth 319 is separated from the second tooth 303. At this time, the rotating plug 302 can rotate inside the gear adjusting block 301. The handle sleeve 311 on the surface of the Z-shaped handle 313 is held, and the rotating plug 302 is rotated until the first L-shaped groove 312 on the surface of the rotating plug 302 is connected with the corresponding second L-shaped groove 320. Then, the sliding cover body 306 drives the third tooth 319 to rotate. 9 moves toward the direction close to the second tooth 303, and the engagement between the second tooth 303 and the third tooth 319 makes it impossible for the rotating plug 302 and the gear adjustment block 301 to rotate relative to each other. At this time, the movement of the hollow rotating table 102 corresponding to the gear can be adjusted by changing the flow direction of the liquid inside the water tank 409. The third spring 308 and the columnar connecting block 307 inside the columnar slide groove 305 make the engagement between the second tooth 303 and the third tooth 319 more stable. The elastic potential energy of the third spring 308 makes the adjusting cover body 309 and the second tooth 303 fit more tightly in the axial direction. The columnar connecting block 307 makes it difficult for the sliding cover body 306 to rotate in the axial direction.

[0069] The surface of the sliding cover body 306 is fixedly connected to the adjusting cover body 309, the Z-shaped handle 313 is located in the third through groove opened on the surface of the adjusting cover body 309, the Z-shaped handle 313 is tubular, and the inside of the adjusting cover body 309 is provided with a plurality of L-shaped tube bodies 317 in a circular array, the L-shaped tube bodies 317 are respectively fixedly connected to the fourth through grooves opened in a circular array on the surface of the Z-shaped handle 313, and the inside of the L-shaped tube bodies 317 are slidably connected to the second T-shaped plugs 318, and the second T-shaped plugs 318 are provided in a circular array.

A fourth spring 315 is provided inside the adjustment round box 314, and both ends of the fourth spring 315 are fixedly connected to the first T-shaped plug 316 and the adjustment round box 314 respectively.

[0070] In the embodiment of the present invention, during the gear adjustment process, by pressing the first T-shaped plug 316, the first T-shaped plug 316 overcomes the elastic potential energy of the fourth spring 315 to squeeze the liquid inside the adjustment round box 314 into the Z-shaped handle 313, and the pressure inside the Z-shaped handle 313 increases, so that the second T-shaped plug 318 moves in a direction away from the inside of the L-shaped tube 317, that is, the second T-shaped plug 318 pushes the sliding cover body 306 in a direction away from the annular groove 304, thereby separating the third tooth 319 from the second tooth 303;

[0071] By loosening the first T-shaped plug 316 , the first T-shaped plug 316 is reset under the action of the elastic potential energy of the fourth spring 315 , so that the third tooth 319 is meshed with the second tooth 303 .

[0072] The surface of the base 101 is fixedly connected to a water tank 409, and a first connecting hose 410 is fixedly connected to the sixth through groove opened on the surface of the water tank 409. The end of the first connecting hose 410 away from the water tank 409 passes through the surface of the U-shaped connecting platform 205 and is fixedly connected to the gear adjustment block 301 through the first connecting hole 411. The inside of the second L-shaped groove 320 is respectively fixedly connected to the first connecting pipe 401, the second connecting pipe 402, the third connecting pipe 403 and the fourth connecting pipe 404. The upper surface of the U-shaped connecting platform 205 is provided with a water storage cavity 407, and the inside of the water storage cavity 407 is slidably connected to the dust plug plate 408. The first connecting hose 410 is fixedly connected to the gear adjustment block 301 through the first connecting hole 411. The ends of the tube 401 and the fourth connecting tube 404 away from the gear adjustment block 301 are both located inside the water storage chamber 407, the surfaces of the first connecting tube 401 and the fourth connecting tube 404 are both installed with the first one-way valve 406, the second connecting tube 402 is connected to the interior of the adjustment chamber 416, the third connecting tube 403 is connected to the interior of the adjustment tube body 413, the first connecting tube 401 and the fourth connecting tube 404 are both fixedly connected to the first through hole opened on the surface of the first connecting tube 401 and the fourth connecting tube 404, the fifth connecting tube 419 is connected to the first through groove opened on the bottom surface of the lifting column 202, and the surface of the fifth connecting tube 419 is installed with the second one-way valve 420.

[0073] A fixed seat 209 is fixedly connected to the surface of the base 101, a pedal 208 is hingedly connected to the surface of the fixed seat 209, a hollow rotating column 210 is rotatably connected to the surface of the fixed seat 209 through two bearing seats, a first rectangular sliding sleeve 211 is fixedly connected in the seventh through groove opened on the surface of the hollow rotating column 210, a rectangular sliding rod 213 is slidably connected inside the first rectangular sliding sleeve 211, the rectangular sliding rod 213 is fixedly connected to the pedal 208, a first spring rod 212 is symmetrically fixedly connected to the surface of the first rectangular sliding sleeve 211, a telescopic end of the first spring rod 212 is fixedly connected to the pedal 208, and the hollow rotating column 210 is connected to the interior of the water tank 409 through a pipe.

[0074] In the embodiment of the present invention, the liquid flow directions in the first connecting pipe 401, the second connecting pipe 402, the third connecting pipe 403 and the fourth connecting pipe 404 correspond to the height increase gear, the horizontal rotation gear, the vertical rotation gear and the height reduction gear respectively;

[0075] When adjusting the flow direction of the liquid inside the water tank 409, the engraver steps on the pedal 208, so that the rectangular sliding rod 213 fixed at the bottom of the pedal 208 moves inside the first rectangular sliding sleeve 211 in the direction of compressing the first spring rod 212, that is, the rectangular sliding rod 213 moves inside the first rectangular sliding sleeve 211 in the direction of approaching the hollow rotating column 210. This process allows the liquid inside the hollow rotating column 210 to enter the inside of the water tank 409, thereby increasing the pressure inside the water tank 409, so that the liquid inside the water tank 409 passes through the first connecting hose 410, the first connecting hole 411, and the first L-shaped groove 312 and enters the inside of one of the second L-shaped grooves 320;

[0076] When the force of stepping on the pedal 208 is released, the pedal 208 is reset under the action of the elastic potential energy inside the first spring rod 212, so that the liquid flows from the corresponding second L-shaped groove 320 through the first L-shaped groove 312, the first connecting hole 411 and the first connecting hose 410 back to the inside of the first connecting hose 410, that is, back to the inside of the hollow rotating column 210;

[0077] When the pedal 208 is stepped on, the liquid in the water tank 409 enters the second L-shaped groove 320 corresponding to the height increase gear in the gear adjustment block 301 through the first connecting hose 410, the first connecting hole 411 and the first L-shaped groove 312, and the liquid enters the first through groove on the bottom surface of the lifting column 202 through the first connecting pipe 401, the second one-way valve 420 and the fifth connecting pipe 419. The second one-way valve 420 here allows the liquid to flow into the interior of the lifting column 202 in only one direction, so that the lifting column 202 moves in the direction away from the supporting sleeve 201. When the pedal 208 is released, the liquid in the water tank 409 enters the second L-shaped groove 320 corresponding to the height increase gear in the gear adjustment block 301 through the first connecting pipe 401, the second one-way valve 420 and the fifth connecting pipe 419. When the pedal 208 is stepped on, the pedal 208 is reset so that the liquid in the water storage chamber 407 passes through the first one-way valve 406 on the surface of the first connecting pipe 401, flows into the second L-shaped groove 320 corresponding to the height increase gear through the first connecting pipe 401, and flows back to the hollow rotating column 210 through the first L-shaped groove 312, the first connecting hole 411, the first connecting hose 410, and the water storage tank 409. The first one-way valve 406 here only allows the liquid in the water storage chamber 407 to flow out of the water storage chamber 407, and the dust blocking plate 408 is used to prevent external impurities from falling into the water storage chamber 407.

[0078] When the pedal 208 is stepped on, the liquid in the water tank 409 enters the second L-shaped groove 320 corresponding to the horizontal rotation gear in the gear adjustment block 301 through the first connecting hose 410, the first connecting hole 411 and the first L-shaped groove 312, and the liquid enters the adjustment chamber 416 through the second connecting pipe 402, so that the rectangular slider 417 drives the first limiting tooth block 214 to separate from the second limiting tooth block 215. When the force of stepping on the pedal 208 is released, the pedal 208 is reset so that the liquid in the adjustment chamber 416 passes through the second connecting pipe 402, the second L-shaped groove 320, the first L-shaped groove 312, the first connecting hole 411, the first connecting hose 410 and the water tank 409 and returns to the inside of the hollow rotating column 210. At this time, the first limiting tooth block 214 is meshed with the second limiting tooth block 215 to brake the rotation of the hollow rotating table 102.

[0079] When the pedal 208 is stepped on to make the liquid in the water tank 409 enter the second L-shaped groove 320 corresponding to the vertical rotation gear in the gear adjustment block 301, the liquid enters the adjustment tube body 413 through the third connecting pipe 403, so that the toothed protrusion on the top of the third rectangular sliding sleeve 415 is separated from the rectangular slider 417, so that the engraver can turn the U-shaped connecting platform 205 by hand to rotate the hollow rotating platform 102 around the central axis of the rotating cylindrical block 216 to the required position. When the force of stepping on the pedal 208 is released, the reset of the pedal 208 makes the toothed protrusion on the top of the third rectangular sliding sleeve 415 combine with the rectangular slider 417, so that the U-shaped connecting platform 205 cannot rotate around the central axis of the rotating cylindrical block 216.

[0080] When the pedal 208 is stepped on to cause the liquid inside the water tank 409 to enter the second L-shaped groove 320 corresponding to the height lowering gear in the gear adjustment block 301, the liquid passes through the fourth connecting pipe 404 and the first one-way valve 406 to enter the water storage chamber 407. When the force of stepping on the pedal 208 is released, under the action of negative pressure, the liquid leaves from the first through groove opened at the bottom of the lifting column 202 through the second one-way valve 420, so that the lifting column 202 moves downward inside the supporting sleeve 201, and the liquid enters the fifth connecting pipe 419 and returns from the fifth connecting pipe 419 through the second L-shaped groove 320, the first L-shaped groove 312, the first connecting hole 411, the first connecting hose 410, and the water tank 409 to the inside of the hollow rotating column 210. The second one-way valve 420 here can only allow the liquid to flow out from the first through groove, and the first one-way valve 406 here can only allow the liquid to enter the water storage chamber 407.

[0081] It should be noted that the shape of the adjustment cavity 416 is composed of a rectangular portion located at the top and a cylindrical portion located at the bottom, so that the rectangular portion constrains the axial rotation of the rectangular slider 417, and the cylindrical portion constrains the movement of the rectangular slider 417;

[0082] The surfaces of the first limiting tooth block 214 and the second limiting tooth block 215 are both provided with a plurality of teeth in an annular array, and the first limiting tooth block 214 and the second limiting tooth block 215 are connected by meshing of the teeth;

[0083] The top of the adjusting tube body 413 is in a rectangular block shape, which is convenient for the adjusting tube body 413 to maintain a sealed sliding connection with the third rectangular sliding sleeve 415. At the same time, the rectangular block convex portion is convenient for fixing the fifth spring 414. A liquid through hole is opened near the top of the surface of the fifth connecting tube 419, which is convenient for liquid to flow from the liquid through hole to between the third rectangular sliding sleeve 415 and the adjusting tube body 413, and the liquid is always constrained below the rectangular block convex portion of the adjusting tube body 413, so as to facilitate the adjustment of the third rectangular sliding sleeve 415 to expand and contract inside the second rectangular sliding sleeve 412;

[0084] The pipe connection method of this embodiment is a fixed connection with threaded thread, or the pipe is fixed in a preset opening, which is a prior art and will not be described in detail here;

[0085] The first connecting pipe 401, the second connecting pipe 402, the third connecting pipe 403, the fourth connecting pipe 404, the first one-way valve 406, the first connecting hole 411, the fifth connecting pipe 419 and the second one-way valve 420 are all connected to the corresponding components through the preset through grooves provided inside the U-shaped connecting platform 205. This is the prior art and will not be described in detail here.

[0086] The hollow rotating platform 102 is cylindrical in shape, and a cylindrical cavity is provided inside the hollow rotating platform 102 to facilitate the placement of the first limiting tooth block 214 and the second limiting tooth block 215. A first circular through hole is provided on the bottom surface to facilitate the connection between the rectangular slider 417 and the first limiting tooth block 214.

[0087] A second circular through opening is formed on the bottom surface of the mounting circular box 207 to facilitate the connection between the rectangular sliding block 417 and the first limiting tooth block 214 .

[0088] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
