The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] See also Figures 1 to 10 , shown is a gear revolving frame in the first embodiment of the present invention, comprising a fixed frame 10, a receiving groove 11 is vertically provided on the fixed frame 10, a support assembly 20 is provided in the receiving groove 11, the support assembly 20 comprises a first supporting structure 21, a plurality of second supporting structures 23 provided above the first supporting structure 21, a first driving structure 22 provided between the first supporting structure 21 and the second supporting structure 23, and a second driving structure 24 provided between adjacent second supporting structures 23, the first supporting structure 21 comprises a first supporting platform 211, a connecting member 211 and the fixed frame 10, The first elastic member 213 of the fixed frame 10, the second supporting structure 23 includes a second supporting platform 232, and a touch platform 231 arranged perpendicular to the second supporting platform 232, a first rotating shaft 233 is provided at the junction of the second supporting platform 232 and the touch platform 231, the first rotating shaft 233 is fixedly connected to the inner side wall of the accommodating groove 11, and an extension structure is slidingly provided in the second supporting platform 232, the extension structure includes an extension rod 31, and a snap structure connecting the extension rod 31 and the second supporting platform 232, the snap structure is used to control the position of the extension rod 31 on the second supporting platform 232.

[0036] It can be understood that the present invention sets a fixing frame 10, and sets a first supporting structure 21 and a plurality of second supporting structures 23 in the receiving groove 11 of the fixing frame 10, wherein the first supporting structure 21 and the second supporting structure 23 are connected by a first driving structure 22, and the plurality of second supporting structures 23 are connected by a second driving structure 24. When a gear needs to be placed, a gear of a suitable size is first placed on one end of the first supporting platform 211, and the first elastic member 213 receives pressure to lift the other end of the first supporting platform 211. The first driving structure 22 drives the touch platform 231, so that the touch platform 231 drives the second supporting platform 232 to rotate around the first rotating shaft 233. When the second supporting structure 23 rotates, it will pass through the second The driving structure 24 drives the second supporting structure 23 above to rotate, thereby rotating each second supporting platform 232 to a horizontal position, so that each gear is spaced apart to prevent the gears from colliding with each other and being damaged. When the rotation stroke is more than half, and the second supporting platform 232 is provided with an extension structure, gravity is greater, and the second supporting platform 232 is easier to rotate. When the second supporting platform 232 is set horizontally, another gear can be placed on it. If the size of the gear is large, the extension structure can be unlocked by the snap structure, and the extension structure is extended to expand the support range of the second supporting platform 232. When the second supporting structure 23 is folded, the extension structure is retracted to prevent the extension structure from interfering with the second supporting structure 23 above.

[0037] The utility model can place gears of various sizes on one fixing frame 10 , thereby greatly improving the applicable scope of the fixing frame 10 .

[0038] Specifically, in this embodiment, a second rotating shaft 212 is provided in the middle of the first supporting platform 211 , the second rotating shaft 212 is fixedly connected to the inner side wall of the accommodating groove 11 , and the first elastic member 213 is located in the middle of the first supporting platform 211 .

[0039] It can be understood that when the second rotating shaft 212 and the first elastic member 213 are both located in the middle of the first support platform 211, the gear presses on the outer end of the first support platform 211, and the action of the first elastic member 213 causes the inner end of the first support platform 211 to rise.

[0040] Furthermore, a first avoidance hole 214 is recessed on one side of the first support platform 211 close to the fixing frame 10, and the first driving structure 22 includes a third rotating shaft 215 arranged in the first avoidance hole 214, a first limiting rod 223 arranged on the inner side wall of the accommodating groove 11, and a first slotted hole rod 221 rotatably connected to the third rotating shaft 215, a first sliding hole 222 is penetrated in the first slotted hole rod 221, and the first limiting rod 223 is located in the first sliding hole 222; a first side of the touch platform 231 close to the fixing frame 10 is recessed There is a second avoidance hole 236, and the second driving structure 24 includes a fourth rotating shaft 235 arranged in the second avoidance hole 236, a second limiting rod 243 arranged on the inner wall of the accommodating groove 11, and a second slot hole rod 241 rotatably connected to the fourth rotating shaft 235, and a second sliding hole 242 is penetrated by the second slot hole rod 241, and the second limiting rod 243 is located in the second sliding hole 242; a limiting block 234 is also provided on the inner wall of the accommodating groove 11, and the limiting block 234 is used to limit the maximum rotation distance of the second support structure 23.

[0041] Understandable, see Figures 11 to 13 , shown is a motion trajectory diagram. When the inner end of the first support platform 211 rises, it will drive the first slotted rod 221 to rise. Due to the limiting effect of the first limiting rod 223, the first slotted rod 221 will only rise according to the predetermined trajectory, thereby causing the first slotted rod 221 to contact the touch platform 231, lifting the touch platform 231, and the touch platform 231 drives the second support platform 232 to rotate around the first rotation axis 233 until the second support platform 232 is close to horizontal and stops at the limiting block 234. Similarly, the lowest touch platform 231 will rise due to the thrust of the first slotted rod below. Since the first slotted rod is in close contact with the lowest touch platform 231, the first slotted rod will push the lowest touch platform to be completely vertical and the lowest second support platform to be completely horizontal.

[0042] Since there is a certain distance between the second slotted rod 241 on the lowest touch platform 231 and the touch platform 231 above it, we set the stroke as follows: when the lowest touch platform 231 rotates to a non-completely vertical position, the lowest second slotted rod 241 contacts the upper touch platform 231; when the lowest touch platform 231 rotates to a completely vertical position, the lowest second slotted rod lifts the upper touch platform 231 to a non-completely vertical position, which makes the second support platform 232 slightly protrude from the accommodating groove 11, just enough for the gear to be placed on it. After the gear is placed on it, gravity causes the second support platform 232 to descend, the touch platform 231 to rise, and then lifts the upper touch platform 231 to a non-completely vertical position. Through this design structure, each gear can be placed in the fixing frame 10 in turn in this cycle.

[0043] Furthermore, a sliding groove 34 is provided on the second support platform 232, and the extension rod 31 is provided in the sliding groove 34. A third avoidance hole 33 communicating with the sliding groove 34 is provided on the second support platform 232. The buckle structure includes a connecting rod 35 connecting the extension rod 31 and the groove wall of the sliding groove 34, a second elastic member 36 sleeved on the connecting rod 35, a fourth avoidance hole 38 provided on the extension rod 31, and a clamping member 37 buckled in the fourth avoidance hole 38. The two ends of the second elastic member 36 are respectively connected to the groove wall of the sliding groove 34 and the extension rod 3 1 connection, the extension rod 31 is provided with a through hole 39 for the connecting rod 35 to pass through; the clamping member 37 includes a clamping plate 371 that is inserted into the third avoidance hole 33 and the fourth avoidance hole 38, and a fifth rotating shaft 373 rotatably connected to the clamping plate 371, the fifth rotating shaft 373 is provided in the third avoidance hole 33, and a torsion spring 374 is sleeved on the fifth rotating shaft 373, the two ends of the torsion spring 374 are respectively connected to the hole wall of the third avoidance hole 33 and the clamping plate 371, and the end of the clamping plate 371 away from the connecting rod 35 is provided with a wedge surface 372.

[0044] It can be understood that when the extension rod 31 is stuck in the second support plate, due to the action of the torsion spring 374, the clamping plate 371 can only rotate toward the direction of the connecting rod 35, and the clamping plate 371 does not have enough space to rotate away from the connecting rod 35. Therefore, the non-wedge-shaped surface 372 of the clamping plate 371 can be against the fourth avoidance hole 38 of the extension rod 31, so that it cannot slide. When the extension rod 31 needs to be extended, the clamping plate 371 is rotated toward the direction of the connecting rod 35, and the extension rod 31 It will first move a short distance toward the position of the connecting rod 35. After the clamping plate 371 disengages from the extension rod 31, the second elastic member 36 will cause the extension rod 31 to pop out to expand the support range of the second support plate. When the extension rod 31 needs to be retracted, the extension rod 31 is pushed toward the direction of the connecting rod 35. The end of the extension rod 31 hits the wedge surface 372, which will cause the clamping plate 371 to rotate until the clamping plate 371 re-enters the fourth avoidance hole 38, and the clamping plate 371 rebounds and presses against the extension rod 31 again.

[0045] Preferably, a protective plate 32 is provided on a side of the extension rod 31 away from the connecting rod 35 .

[0046] It can be understood that the enclosure plate 32 can prevent the gear from being too tilted in one direction and the shaft hole of the gear from being too large, which may cause the gear to fall from the extension rod 31.

[0047] In summary, the gear turnover frame in the above embodiment of the present invention can place gears of various sizes on one fixed frame, thereby greatly improving the scope of application of the fixed frame.
