Optionally, in this embodiment, as shown in fig. 2, a limit plate 270 may be fixedly disposed in the box body 210, the limit plate 270 is provided with a limit hole 271, and the gear shaft 241 is rotatably inserted into the limit hole 271. Here, in a specific form in which the gear shaft 241 is pivotally connected to the box body 210, the limiting hole 271 limits the gear shaft 241, and the gear shaft 241 is limited to rotate only in the inner circumferential direction of the limiting hole 271, so that the stability of the gear shaft 241 being mounted to the box body 210 is improved, and the meshing transmission of the gear shaft 241 with the first rack 242 and the second rack 243 is ensured. Specifically, the top wall of the housing may be provided with a pivot hole 212, the top of the gear shaft 241 may be rotatably inserted into the pivot hole 212, and the pivot hole 212 and the limiting hole 271 limit the gear shaft 241 at different positions in the length direction of the gear shaft 241, thereby further improving the stability of the gear shaft 241 in pivoting the box body 210; preferably, the first bearing 213 may be sleeved between the hole wall of the pivot hole 212 and the gear shaft 241, the second bearing 272 may be sleeved between the hole wall of the limiting hole 271 and the gear shaft 241, and the arrangement of the first bearing 213 and the second bearing 272 can ensure the smoothness of the rotation of the gear shaft 241 relative to the pivot hole 212 and the limiting hole 271 and reduce the friction resistance between the gear shaft 241 and the hole walls of the pivot hole 212 and the limiting hole 271 on the basis of improving the accuracy of the position where the gear shaft 241 is rotationally matched with the pivot hole 212 and the limiting hole 271.
Specifically, in this embodiment, the top end of the gear shaft 241 may be provided with a handle 244, and an operator may apply force to the gear shaft 241 by rotating the handle 244, so as to improve the convenience of the connecting assembly 200; preferably, the top end of the gear shaft 241 is lower than the top surface of the box body 210, and the handle 244 is detachably and fixedly connected with the top end of the gear shaft 241, when the gear shaft 241 needs to be rotated, the handle 244 is connected to the top end of the gear shaft 241, and the gear shaft 241 is rotated by the handle 244; when the gear shaft 241 does not need to be rotated, the handle 244 can be detached, and the top end of the gear shaft 241 does not protrude out of the box body 210, so that adverse effects on the flatness of the top surface of the supporting table are reduced.
In this embodiment, as shown in fig. 2 and fig. 3, a first guide seat 280 and a second guide seat 290 may be fixedly connected to an outer side wall of the box body 210, a first guide hole 281 is disposed in the first guide seat 280, and the first inserting arm 220 is slidably inserted into the first guide hole 281; a second guide hole 291 is formed in the second guide seat 290, and the second insertion arm 230 is slidably inserted into the second guide hole 291. When the gear shaft 241 drives the first and second plugging arms 220 and 230 to perform telescopic motion relative to the case 210 through the first and second racks 242 and 243, the first plugging arm 220 can slide and stretch in the first guide hole 281, and the second plugging arm 230 can slide and stretch in the second guide hole 291, on one hand, the first and second guide seats 280 and 290 can limit the telescopic stroke of the first and second plugging arms 220 and 230, respectively, so as to ensure the matching connection between the first and second plugging arms 220 and 230 and the first and second support plates 320 and 420; on the other hand, after the first inserting arm 220 is connected with the first supporting plate 320 and the second inserting arm 230 is connected with the second supporting plate 420, the first guide seat 280 and the second guide seat 290 can respectively support the first inserting arm 220 and the second inserting arm 230, so as to reduce the occurrence of the situation that the first inserting arm 220 and the second inserting arm 230 are correspondingly stressed and bent or even broken when the supporting table is subjected to a downward acting force, thereby improving the connection and support firmness of the first inserting arm 220 and the second inserting arm 230 to the first supporting plate 320 and the second supporting plate 420. Specifically, the first guide 280 and the second guide 290 may be fixed to the case 210 by bolts, screws, or the like.
In this embodiment, as shown in fig. 2, one of the hole wall of the first guiding hole 281 and the outer wall of the first inserting arm 220 is provided with a first limiting groove 282 along the length direction thereof, the other one is fixedly connected with a first limiting boss 221, and the first limiting boss 221 is slidably inserted into the first limiting groove 282. The first inserting arm 220 slides along the length direction of the first guide hole 281 under the driving action of the driving member 240, and the first guide hole 281 guides and limits the sliding of the first inserting arm 220; meanwhile, in the sliding process, the first limiting boss 221 slides in the first limiting groove 282 along the length direction thereof, on one hand, the first limiting boss 221 and the first limiting groove 282 are matched to further guide and limit the sliding of the first inserting arm 220, and can limit the circumferential position of the first inserting arm 220, so as to improve the stability of the telescopic sliding of the first inserting arm 220; on the other hand, the two ends of the first limit groove 282 in the length direction can limit the sliding stroke of the first inserting arm 220, and when the first limit boss 221 abuts against the side wall of one end of the first limit groove 282 of the cartridge 210, the gear shaft 241 can not rotate in the first direction any more, and then the first inserting arm 220 already extends out of the first guide seat 280 and can be connected with the first supporting plate 320 in a matching manner; when the first limit protrusion 221 abuts against one end of the first limit groove 282 close to the box body 210, the gear shaft 241 can no longer rotate in the second direction, and the first inserting arm 220 has already separated from the first supporting plate 320, and no longer interferes with the moving or folding operation of the first supporting plate 320. The first limit boss 221 and the first limit groove 282 are disposed to effectively limit the rotation of the gear shaft 241, so that the driving member 240 cannot be used due to the fact that the gear shaft 241 is separated from the first rack 242 by an excessively large rotation angle on the basis of the telescopic movement of the first inserting arm 220. Specifically, as shown in fig. 2, the first limiting groove 282 is disposed on the hole wall of the first guiding hole 281, and the first limiting protrusion 221 is fixedly disposed on the outer wall of the first inserting arm 220; of course, the first limiting groove 282 may be disposed on the outer wall of the first inserting arm 220, and the first limiting protrusion 221 may be fixedly disposed on the hole wall of the first guiding hole 281; preferably, the first limit grooves 282 and the first limit bosses 221 may be multiple sets, and are arranged at intervals along the circumferential direction of the first guide hole 281.
Similarly, one of the hole wall of the second guiding hole 291 and the outer wall of the second inserting arm 230 is provided with a second limiting groove 292 along the length direction thereof, the other one is fixedly connected with a second limiting boss 231, and the second limiting boss 231 is slidably inserted into the second limiting groove 292. The second limiting groove 292 can guide and limit the movement stroke of the second limiting boss 231, correspondingly limit the rotation angle of the gear shaft 241, and reduce the phenomenon that the rotation angle of the gear shaft 241 is too large to separate from the second rack 243 to cause the driving member 240 to be unable to use on the basis of realizing the telescopic movement of the second inserting arm 230. The arrangement and operation principle are similar to the first position-limiting groove 282 and the second position-limiting protrusion 231, and are not described herein again.
