[0036] Preferably, the first clamp block 7, the second clamp block 10 and the fitting 111 can be arranged to be detachably connected, and the selectable detachable connection methods include magnetic suction type, card slot snap-on type, etc., to prevent the fitting 111 from falling off from between the two first clamp blocks 7 or the two second clamp blocks 10 when the first clamp block 7 and the second clamp block 10 are moved.

[0037] In order to facilitate the synchronous movement of the first clamping block 7 and the second clamping block 10, a first telescopic cylinder 72 is fixed on both side surfaces of the first clamping block 7 parallel to the linear guide rail 2 through the first mounting plate 71, and the telescopic rods of the first telescopic cylinder 72 are both facing the second sliding block 4. A socket plate 101 is fixedly installed on both side surfaces of the second clamping block 10 parallel to the linear guide rail 2, and a first round through hole 1011 is provided on the socket plate 101, and the telescopic rod of the first telescopic cylinder 72 can be inserted into the first round through hole 1011; in order to facilitate the splicing and fitting of the blocking shells 11 on both sides, when the position height and telescopic length of the blocking shells 11 on both sides are adjusted, when it is necessary to synchronously move the first clamping block 7 and the second clamping block 10, the first telescopic cylinder 72 is turned on at this time, and the telescopic rod of the first telescopic cylinder 72 is extended and inserted into the corresponding first round through hole 1011, so that the first clamping block 7 located at the bottom is connected with the second clamping block 10 located at the bottom, and the first clamping block 7 located at the top is connected with the second clamping block 10 located at the top, so as to achieve the purpose of facilitating the synchronous movement of the first clamping block 7 and the second clamping block 10.

[0038] In order to facilitate the control of the blocking component to automatically adjust the position height, a threaded rod 12 placed vertically upward is fixedly connected to the support platform 5, the lower end of the threaded rod 12 passes through the support platform 5 and is rotatably connected to the support platform 5, the threaded rod 12 is located on the side of the first slide rail 6 away from the second slider 4, the first clamping block 7 is provided with a second round through hole, the diameter of the second round through hole is larger than the diameter of the threaded rod 12, the threaded rod 12 passes through the second round through hole, and a movable groove is provided on the first clamping block 7 located above the first slide rail 6. The second mounting plates 13 are fixed on the first mounting plates 71 on both sides of the first clamping block 7 at the top, and the second telescopic cylinders 131 are fixedly mounted on the second mounting plates 13. The telescopic rods of the two second telescopic cylinders 131 are placed opposite to each other, and the telescopic rods of the second telescopic cylinders 131 are fixedly connected with the first connecting blocks 132, and the first connecting blocks 132 are fixedly connected with the splicing blocks 133. The splicing blocks 133 are provided with semicircular thread grooves. After the two splicing blocks 133 are attached, a complete thread groove can be formed and meshed with the threaded rod 12.

[0039] The second telescopic cylinder 131 is turned on, and the telescopic rod of the second telescopic cylinder 131 is extended to drive the two splicing blocks 133 to approach each other and fit together, and then the threaded rod 12 is rotated, and the threaded rod 12 is threadedly engaged with the splicing block 133 for transmission, and the splicing block 133 drives the first connecting block 132, the second telescopic cylinder 131, the second mounting plate 13, the first mounting plate 71, and the upper first clamping block 7 in turn, and finally the upper first clamping block 7 drives the blocking assembly and the lower first clamping block 7; correspondingly, the first telescopic cylinder 72 can be turned on, so that the telescopic rod of the first telescopic cylinder 72 is inserted into the first round through hole 1011, so that the blocking shells 11 on both sides move synchronously, so as to achieve the purpose of facilitating the control of the blocking assembly to automatically adjust the position height.

[0040] When the height adjustment of the blocking component position is completed, the length of the blocking shell 11 needs to be adjusted according to the height of the required blocking column. In order to facilitate the telescopic adjustment of the blocking shell 11 according to the length of the column, a pair of parallel first slide bars 14 are fixed on the support platform 5. The first slide bar 14 is coaxially placed with the first slide rail 6. The first slide bar 14 is located on both sides of the threaded rod 12, and the symmetry line between the two first slide bars 14 is coaxially placed with the linear guide rail 2. The first slide bar 14 passes through the first clamping block 7, and the first clamping blocks 7 can slide along the first slide bar 14.

[0042] In this embodiment, the lengths of the first spring 141 and the second spring 151 are both greater than the lengths of the required blocking columns. After the blocking assembly and the first clamping block 7 at the bottom are driven by the threaded transmission of the threaded rod 12 and the splicing block 133, the first clamping block 7 at the bottom is moved to the position of the lower cross bar connected to the required blocking column, and the first telescopic cylinders 72 on both sides of the first clamping block 7 at the bottom are opened, so that the telescopic rods of the first telescopic cylinders 72 on both sides of the first clamping block 7 at the bottom are extended and inserted into the first round through holes 1011 on the jack plates 101 on both sides of the corresponding second clamping block 10, and then the screws are turned again. The threaded rod 12 is threadedly transmitted with the splicing block 133, and the upper first clamping block 7 is moved up and down according to the required length of the blocking column. At the same time, under the elastic force of the first spring 141 and the second spring 151, the first telescopic cylinder 72 between the lower first clamping block 7 and the lower second clamping block 10 is kept in extrusion contact with the cross bar connected to the lower end of the required blocking column, and then the upper first clamping block 7 and the upper second clamping block 10 drive the blocking shell 11 to be telescopically adjusted according to the length of the column, thereby achieving the purpose of facilitating the telescopic adjustment of the blocking shell 11 according to the length of the column.

[0043] In order to facilitate the synchronous movement of the blocking shells 11 on both sides, the first telescopic cylinder 72 connected between the upper first clamping block 7 and the upper second clamping block 10 is convenient to pass through the cross bar. The number of first telescopic cylinders 72 installed on the first mounting plates 71 on both sides of the first clamping block 7 on the upper side of the first slide rail 6 is two.

[0045] Turn on the rotating motor 16, and the output end of the rotating motor 16 drives the first rotating shaft 161, the first rotating shaft 161 drives the first gear 162, the first gear 162 rotates to drive the toothed plate 164, the toothed plate 164 drives the second rotating shaft 163, the second rotating shaft 163 drives the second gear 165, the second gear 165 drives the third gear 166, and the third gear 166 rotates to drive the rotation of the threaded rod 12, thereby achieving the purpose of conveniently controlling the rotation of the threaded rod 12.

[0046] In order to facilitate the control of the rotation of the roller 81 and realize the purpose of rotating the second slide rail 9 from horizontal placement to vertical placement, a fixed sleeve is provided with a toothless gear 17 at one end of the roller 81 away from the rotating motor 16. The teeth of the toothless gear 17 are only distributed on a quarter of the circumference, and when the second slide rail 9 is in a horizontal position, the teeth of the toothless gear 17 are located at the oblique lower angle position of the toothless gear 17 close to the first slider 3. A first slide groove 1001 is provided on the base 1000. The first slide groove 1001 is coaxially placed with the linear guide rail 2.

[0047] After the base 1000 is inserted into one side of the guardrail near the end of the second slider 4, it is not convenient to manually directly rotate the roller 81 to drive the swing assembly 8. At this time, the first spur rack 18 is pushed to make the first spur rack 18 approach the toothless gear 17 along the first slide groove 1001. The first spur rack 18 engages with the toothless gear 17 to drive the toothless gear 17 to rotate, and the toothless gear 17 drives the roller 81 to rotate, so as to facilitate the control of the rotation of the roller 81 and realize the purpose of rotating the second slide rail 9 from horizontal placement to vertical placement.

Finally, the third gear 166 drives the threaded rod 12. However, since the two splicing blocks 133 are separated, the rotation of the threaded rod 12 will not cause the movement of the first clamping block 7 located above; at the same time, the rotation of the first rotating shaft 161 drives the turntable 19, and the turntable 19 drives the paddle plate 191.
