Description

Technical Field

[0001] The invention relates to the field of automation equipment, and in particular to an automatic tag conveying, threading and knotting device and a method thereof. Background Art

[0002] Hangtags are often used in clothing and other fields. The graphic design on the hangtag can record advertisements, ingredient descriptions, washing instructions, barcodes, certification marks and other content. Through the hanging rope, one or more hangtags can be put on and hung on the clothing. At present, there are some automatic hangtag threading devices that can realize the threading of a hangtag or the stacking and threading of multiple hangtags. They usually include a hangtag conveying device, a hangtag conveying device and a threading device, etc. Usually, the pre-separated hangtags are sent to the threading position through the hangtag conveying device, and then one or more hangtags are conveyed to the threading position and inserted into the hangtag through one or more hangtag conveying devices. However, the existing hangtag threading device usually has multiple hangtag conveying devices that act in sequence to place the hangtags, and the next hangtag stacking operation is performed after one hangtag stacking operation is completed, which has low production efficiency. In addition, the existing hangtag conveying device also needs to cooperate with the hangtag pushing structure, the hangtag flipping structure, etc., the hangtag is easy to be placed upside down, and the device structure is complicated. When multiple hang tags need to be stacked, the existing hang tag threading device usually needs to use multiple hang tag conveying devices to place the hang tags in sequence at the same preset position, and then proceed to the next hang tag stacking operation after completing one hang tag stacking operation. The production efficiency is low, and the through holes of multiple hang tags are difficult to align with each other.

[0003] In addition, it is difficult for the existing tag threading device to directly use the wound rope for threading. When using the wound rope for threading, it is necessary to tie knots on the ropes on both sides of the tag to prevent the tag from falling off the rope after the rope is cut. At present, most of the ropes that are wound into a roll can only be threaded and knotted manually, which has low production efficiency. Summary of the invention

[0035] like Figures 1 to 2 As shown, the automatic tag conveying, stacking, stringing and knotting device of this embodiment includes a tag conveying device 1000, a tag translation device 2000 and a tag stringing and knotting device 3000.

[0036] like Figures 3 to 7 As shown, the hanging card conveying device 1000 includes a material trough component 1100 and a pick-and-place mechanism 1200. The material trough component 1100 includes a plurality of placement slots 1110, and the placement slots 1110 are used to stack and place a plurality of flat hanging cards.

[0037] The pick-and-place mechanism 1200 includes a mounting block 1210, a sliding seat 1220, a first cylinder 1230, a second cylinder 1240, a vacuum suction cup 1250, and a laser sensor 1260. The mounting block 1210 spans over the placement slot 1110, the sliding seat 1220 is movably connected to the mounting block 1210 directly or indirectly, the first cylinder 1230 is used to drive the sliding seat 1220 to move along the extension direction of the mounting block 1210, for example, the first cylinder 1230 is connected to the mounting block 1210 and extends along the extension direction of the mounting block 1210, and the sliding seat 1220 is connected to the moving end of the first cylinder 1230. The number of the second cylinders 1240 is the same as the number of the placement slots 1110. The second cylinders 1240 are connected to the sliding seat 1220. The telescopic end of each second cylinder 1240 is connected to a vacuum suction cup 1250 and a laser sensor 1260. The suction direction of the vacuum suction cup 1250 and the emission and detection direction of the laser sensor 1260 are both downward. The lower end of the vacuum suction cup 1250 is lower than the lower end of the laser sensor 1260 to prevent the laser sensor 1260 from colliding with the tag. The second cylinder 1240 is used to drive the vacuum suction cup 1250 and the laser sensor 1260 to move up and down synchronously. The distance that the second cylinder 1240 moves downward toward the placement slot 1110 is controlled according to the signal obtained by the laser sensor 1260. The laser sensor 1260 can be used to detect the distance between the laser sensor 1260 and the topmost hangtag in the placement slot 1110. The laser sensor 1260 has the advantages of fast detection speed and high detection accuracy. When the detected distance reaches the point where the vacuum suction cup 1250 can suck up the topmost hangtag, the second cylinder 1240 stops moving downward. At this time, the vacuum suction cup 1250 and the topmost hangtag are in contact or separated by a gap. As long as the vacuum suction cup 1250 can suck up the topmost hangtag, it is sufficient. The second cylinder 1240 corresponds to the placement slot 1110 in position. It can be seen that the hangtag conveying device of this embodiment can convey multiple different hangtags at the same time, and can achieve hangtag stacking in cooperation with the hangtag translation device 2000 at the discharge end. As an example, assuming that the number of placement slots 1110 and second cylinders 1240 are both N, N is an integer greater than or equal to 2, the first second cylinder can absorb the first tag on the first placement slot and place the first tag to the first preset discharge position, similarly, the second second cylinder to the Nth second cylinder can respectively absorb the second to Nth tags on the second placement slot to the Nth placement slot and place the corresponding tags to the second to Nth preset discharge positions, and these discharge operations are performed simultaneously.After completing a synchronous discharge operation, the tag translation device 2000 translates the tag on the nth preset discharge position to the n+1th preset discharge position, where n is an integer from 1 to N-1, and then the tag conveying device performs the next discharge operation. At this time, the tag conveying device places the n+1th tag on the basis of an existing group of tags translated from the nth preset discharge position at the n+1th preset discharge position, thereby realizing the stacking of multiple tags, and stacking multiple groups of tags in sequence at different preset discharge positions, which can improve the stacking efficiency.

[0038] Specifically, the plurality of placement slots 1110 are arranged in a direction perpendicular to the mounting block 1210. The sliding seat 1220 extends in a direction perpendicular to the mounting block 1210, and the plurality of second cylinders 1240 are connected to the sliding seat 1220. The second cylinder 1240 may include a main cylinder body 1241 and a plurality of guide rods 1242 symmetrically arranged relative to the main cylinder body 1241, so as to improve the stability of the movement of the telescopic end of the second cylinder 1240. The second cylinder 1240 may be connected to the side of the sliding seat 1220.

[0039] Specifically, the plurality of second cylinders 1240 are symmetrically distributed relative to the mounting block 1210 , so that the sliding seat 1220 is subjected to a more uniform force.

[0040] Specifically, the pick-and-place mechanism 1200 further includes two support columns 1270 , and both ends of the mounting block 1210 are supported on the two support columns 1270 , respectively, so that the mounting block 1210 has a stable structure.

[0041] Specifically, the pick-and-place mechanism 1200 also includes a connecting plate 1280 and a fixed seat 1281, the vacuum suction cup 1250 and the fixed seat 1281 are connected to the lower end of the connecting plate 1280, the laser sensor 1260 is installed in the fixed seat 1281, and the telescopic end of the second cylinder 1240 is connected to the upper end of the connecting plate 1280.

[0042] Specifically, the trough assembly includes a bottom plate 1120 and a plurality of parallel side plates 1130 vertically and detachably connected to the bottom plate 1120, and a placement slot 1110 is formed between two adjacent side plates 1130. The number of the side plates 1130 is an even number, and a placement slot 1110 is formed between every two side plates 1130. By adjusting the distance between every two side plates 1130, the width of the placement slot 1110 can be made equal to the width of the hangtag, so as to prevent the hangtag from moving in the width direction in the placement slot 1110 and causing the vacuum suction cup 1250 to fail to absorb the hangtag at the top.

[0043] Specifically, the side plate 1130 includes a positioning block 1131 and a baffle 1132. The positioning block 1131 is connected to the lower end of the baffle 1132 and is located outside the placement groove 1110. The baffle 1132 forms the side wall of the placement groove 1110. A groove 1133 is provided at the lower end of the positioning block 1131. A magnet 1134 is placed in the groove 1133. The magnet 1134 attracts the bottom plate 1120. It can be seen that the side plate 1130 is detachably connected to the bottom plate 1120 through the attraction of the magnet 1134, and has a simple structure and is easy to assemble and disassemble.

[0044] Specifically, the bottom plate 1120 is provided with a first limiting groove 1121 and a second limiting groove 1122 in a direction perpendicular to the side plate 1130, and the first limiting groove 1121 and the second limiting groove 1122 are perpendicular to the extension direction of the mounting block 1210. The two ends of the positioning block 1131 include two protrusions 1135 extending downward and respectively cooperating with the first limiting groove 1121 and the second limiting groove 1122, and the lower ends of the two protrusions 1135 are respectively provided with grooves 1133, and magnets 1134 are placed in the grooves 1133. The first limiting groove 1121 and the second limiting groove 1122 can prevent the side plate 1130 from moving along the extension direction of the mounting block 1210, so that the side plate 1130 can only adjust the width of the placement groove 1110 in the direction perpendicular to the mounting block 1210.

[0045] Specifically, a vertical positioning pin 1123 is also connected to the bottom plate 1120. The positioning pin 1123 is used to cooperate with the through hole of the hangtag. When the vacuum suction cup 1250 sucks the hangtag in the placement slot 1110 at the preset material picking position, the relative position of the vacuum suction cup 1250 and the through hole of the hangtag is fixed. When the vacuum suction cup 1250 moves and releases the hangtag at the preset material discharge position, the through hole of the hangtag can be aligned with the preset position of the through hole at the preset material discharge position. By controlling the distance of each movement of the hangtag translation mechanism to be equal to the distance between the positioning pins 1123 on two adjacent placement slots 1110, the through holes of different hangtags can be aligned with each other when they are stacked. Preferably, the positioning pin 1123 is staggered with the vacuum suction cup 1250 and the laser sensor 1260.

[0046] Implementing the tag conveying method on the tag conveying device includes repeatedly performing the following steps:

[0047] Step 1: The first cylinder 1230 drives the sliding seat 1220 to move until the second cylinder 1240 is located above the preset material taking position in the placement groove 1110 .

[0048] Step 2: The second cylinder 1240 drives the vacuum suction cup 1250 and the laser sensor 1260 to move downward. The laser sensor 1260 detects the distance from the laser sensor 1260 to the uppermost tag of the placement slot 1110, and controls the downward distance of the second cylinder 1240 according to the distance signal detected by the laser sensor 1260.

[0049] Step 3: The vacuum suction cup 1250 sucks up the top hang tag.

[0050] Step 4: The second cylinder 1240 drives the vacuum suction cup 1250 and the laser sensor 1260 to move upward and separate from the placement groove 1110.

[0051] Step 5: The first cylinder 1230 drives the sliding seat 1220 to move until the second cylinder 1240 is located above the preset discharge position outside the placement groove 1110.

[0052] Step 6: The second cylinder 1240 drives the vacuum suction cup 1250 to move downward to a preset discharge position, and the vacuum suction cup 1250 releases the tag.

[0053] like Figures 8 to 10 As shown, the hangtag translation device 2000 includes a first support mechanism 2100, a second support mechanism 2200, a clamping mechanism 2300, a moving mechanism 2400 and a pin positioning mechanism 2500. The hangtag translation device 2000 cooperates with the automated hangtag conveying device 1000 to place different hangtags at different positions simultaneously or almost simultaneously, and translates the hangtags for stacking, thereby improving the stacking efficiency of the hangtags.

[0054] Specifically, the first supporting mechanism 2100 and the second supporting mechanism 2200 are parallel to each other, upper surfaces of the first supporting mechanism 2100 and the second supporting mechanism 2200 form supporting surfaces for the hang tag, and a channel 2110 is formed between the first supporting mechanism 2100 and the second supporting mechanism 2200.

[0055] The ejector pin positioning mechanism 2500 includes ejector pins 2510, the number of which is the same as or one more than the number of placement slots 1110, and the ejector pins 2510 can extend or retract from the first support mechanism 2100. The ejector pins 2510 are used to locate the through holes of the hang tag to prevent the hang tag from being placed at the position corresponding to the ejector pins 2510 or the clamping mechanism 2300 from clamping or releasing the hang tag, causing the through holes to move and become misaligned due to the hang tag being clamped or lifted, thereby affecting the subsequent rope threading operation.

[0056] The clamping mechanism 2300 includes a clamping assembly, the number of which is the same as the number of placement slots 1110, and each group of clamping assemblies includes an upper clamping block 2310 and a lower clamping block 2320. The upper clamping block 2310 and the lower clamping block 2320 are used to move toward each other until they clamp the hangtag at the position corresponding to the ejector pin 2510 in the channel 2110, and / or the upper clamping block 2310 and the lower clamping block 2320 are also used to move away from each other so as to place the hangtag on a portion of the support surface where no ejector pin 2510 is provided or on the corresponding position of the next ejector pin 2510 on the support surface. Specifically, the position to which the ejector pin is provided or not provided can be determined as needed. For example, moving to the corresponding position of the next ejector pin 2510 can be used to stack the next hangtag or flip the hangtag. For example, moving to a position without an ejector pin and then pressing it through other mechanisms can be aligned with the through hole for threading the rope.

[0057] The moving mechanism 2400 is used to drive the clamping mechanism 2300 to move along the extension direction of the channel 2110. For example, when the clamping mechanism 2300 clamps the hangtag, the moving mechanism 2400 drives the clamping mechanism 2300 to move so as to realize the movement of the hangtag; when the clamping mechanism 2300 releases the hangtag, the hangtag can be placed at the next required position. At this time, the moving mechanism 2400 drives the clamping mechanism 2300 to move so that the clamping mechanism 2300 leaves the top pin corresponding position, and does not hinder the placement of the next hangtag at the top pin corresponding position. When it is necessary to clamp the hangtag at the top pin corresponding position, the moving mechanism 2400 drives the clamping mechanism 2300 to move to the original top pin corresponding position, in preparation for clamping the hangtag at the top pin position and moving it to the next top pin position or a preset position.

[0058] Specifically, the number of clamping assemblies is N, and the number of ejector pins 2510 is N or N+1, where N is an integer greater than or equal to 1. The N clamping assemblies are arranged at the same spacing along the extension direction of the channel 2110, and the N or N+1 ejector pins 2510 are arranged at the same spacing as above along the extension direction of the channel 2110, so that the clamping assemblies can be moved in conjunction with each other by the same distance along the extension direction of the channel 2110 to put the hangtag into the working position of the next clamping assembly. The Mth clamping assembly in the extension direction of the channel 2110 is used to move the hangtag on the Mth ejector pin 2510 to the corresponding position of the M+1th ejector pin 2510, where M is an integer greater than or equal to 1 and less than N; the Nth clamping assembly in the extension direction of the channel 2110 is used to move the hangtag on the Nth ejector pin 2510 to the portion of the support surface where the ejector pin 2510 is not provided or to the corresponding position of the N+1th ejector pin 2510 on the support surface.

[0059] The tag translation device 2000 also includes a flipping mechanism 2600, which is used to flip and fold the double-page tag. The double-page tag includes a fold line and two through holes symmetrical with respect to the fold line. When the double-page tag is placed on the support surface, one of the through holes is aligned with the ejector pin 2510, and the other through hole is aligned with the through hole after being flipped and folded by the flipping mechanism 2600. The flipping mechanism 2600 includes a rotating cylinder 2610 and a swing arm pressing plate 2620. The rotating cylinder 2610 is connected to the position of the first support mechanism 2100 or the second support mechanism 2200 corresponding to the ejector pin 2510. The rotating cylinder 2610 is connected to the swing arm pressing plate 2620 and the rotating cylinder 2610 is used to drive the swing arm pressing plate 2620 to rotate on the support surface to fold the tag. The swing arm pressure plate 2620 is bent, and the rotary cylinder 2610 is connected to the position corresponding to the N+1th ejector pin 2510, that is, after all the hangtags are stacked, the double-page hangtag is flipped and folded in half, and the middle of the folded double-page hangtag can cover multiple single-page hangtags.

[0060] As a specific example, when the number of clamping assemblies is 4, the number of ejectors may be 5. The card picking and placing device coordinated with the hangtag translation device of this embodiment can simultaneously place the first hangtag at the corresponding position of the first ejector, the second hangtag at the corresponding position of the second ejector, the third hangtag at the corresponding position of the third ejector, and the fourth hangtag at the corresponding position of the fourth ejector. When placing the hangtags, the clamping assemblies leave the corresponding positions of the ejectors and do not hinder the placement of the hangtags in space. The ejectors extend to position the hangtags. The first hangtag may be a double-page hangtag, and a flip mechanism 2600 may be provided at the corresponding position of the fifth ejector. When the tag needs to be transferred, the first clamping assembly clamps the tag at the corresponding position of the first ejector, the second clamping assembly clamps the tag at the corresponding position of the second ejector, the third clamping assembly clamps the tag at the corresponding position of the third ejector, the fourth clamping assembly clamps the tag at the corresponding position of the fourth ejector, the ejector retracts, and then the moving mechanism 2400 drives the first clamping assembly, the second clamping assembly, the third clamping assembly and the fourth clamping assembly to move the same distance, and respectively moves the tag at the corresponding position of the first ejector to the corresponding position of the second ejector, the tag at the corresponding position of the second ejector to the corresponding position of the third ejector, the tag at the corresponding position of the third ejector to the corresponding position of the fourth ejector, and the tag at the corresponding position of the fourth ejector to the corresponding position of the fifth ejector. Then, the ejector pin extends to position the hangtag, the first clamping assembly, the second clamping assembly, the third clamping assembly and the fourth clamping assembly are loosened and moved away, and the card picking and placing device continues to place the first to fourth hangtags at the corresponding positions of the first to fourth ejector pins, respectively, so as to achieve the stacking of different groups of hangtags in sequence and at the same time at the corresponding positions of different ejector pins, thereby improving production efficiency. At the corresponding position of the fifth ejector pin, the flipping mechanism 2600 flips the double-page hangtag in half, and the folded hangtag combination is transferred to other positions for threading and other operations. Repeating the above steps can achieve continuous stacking.

[0067] like Figures 11 to 14 As shown, the tag string threading and knotting device 300 includes a winding mechanism 3100, a rope pulling mechanism 3200, a knotting mechanism 3300 and a cutting mechanism 3400. Among them, the winding mechanism 3100 is used for string threading, the rope pulling mechanism 3200 is used for pulling the hanging rope to facilitate knotting, the knotting mechanism 3300 is used for knotting the hanging rope, and the cutting mechanism 3400 is used to cut the hanging rope that has been threaded with the tag and tied.

[0068] The winding mechanism 3100 includes a rope feeding assembly, a rope feeding needle 3110 and a first clamping assembly 3120. The rope feeding assembly transmits the rope to the rope feeding needle 3110. The rope feeding needle 3110 is used to move back and forth so as to insert the rope into the through hole of the hangtag. The first clamping assembly 3120 is used to clamp or loosen the end of the rope inserted into the hangtag, so that when the rope pulling mechanism 3200 clamps the hangtag and moves, the ropes on both sides of the hangtag can move with the rope pulling mechanism 3200 and contact the knotting mechanism 3300, and the ropes on either side or both sides of the hangtag can be knotted as needed.

[0069] Specifically, the winding mechanism 3100 further includes a rope roll placement rack 3130, a rope reversing pipe 3140, a driving wheel 3150 and a guide wheel 3160. The rope roll placement rack 3130 is used to place the wound rope. The rope reversing pipe 3140 allows the rope to pass through and directs the rope toward the driving wheel 3150 to prevent the rope from slipping off the driving wheel 3150 due to the rope pulling out direction being different from the driving wheel 3150. The driving wheel 3150 is used to drive the rope coming out of the rope annular pipe 3140 to move. The guide wheel 3160 allows the rope coming out of the driving wheel 3150 to bypass. After passing through the guide wheel 3160, the rope extends to the rope feeding needle 3110. The guide wheel 3160 is preferably a ceramic guide wheel, which has the advantages of smooth surface and wear resistance.

[0070] Specifically, the winding mechanism 3100 also includes a driven wheel 3151, which is located on one side of the driving wheel 3150. The sling rope passes between the driving wheel 3150 and the driven wheel 3151. The driven wheel 3151 is used to press the sling rope toward the driving wheel 3150 to prevent the sling rope from sliding on the driving wheel 3150 and being unable to be moved by the driving wheel 3150.

[0071] Specifically, the guide wheel 3160 includes an upper guide wheel group 3161, a lower guide wheel group 3162 and a lower guide wheel group driving member 3163. The lower guide wheel group 3162 has one less guide wheel than the upper guide wheel group 3161. The lower guide wheel group driving member 3163 is used to drive the lower guide wheel group 3162 to move up and down. When the rope feeding needle 3110 passes the hanging rope through the hanging tag or the rope pulling mechanism 3200 pulls the hanging rope, the lower guide wheel group driving member 3163 can drive the lower guide wheel group 3163 to move upward to cooperate with the pulling rope, thereby playing a buffering role, reducing the pressure of the driving wheel 3150 to move the hanging rope, and when the hanging rope is not pulled or the pulling speed is slow, the lower guide wheel group driving member 3163 can drive the lower guide wheel group 3162 to move downward, thereby playing a role of storing the hanging rope. The lifting rope coming out of the driving wheel 3150 passes through the guide wheel of the upper guide wheel group 3161 and the guide wheel of the lower guide wheel group 3162 alternately in turn, and then extends from the upper guide wheel group 3161 and extends to the rope feeding needle 3110.

The second clamping assembly 3230 is used to clamp or release the hangtag. When the hangtag is inserted into the hangtag and the second clamping assembly 3230 clamps the hangtag, the movement of the first driving assembly 3210 and / or the second driving assembly 3220 can drive the hangtag to move. The second clamping assembly 3230 can clamp the horizontally placed hangtag from top to bottom. The hangtag may be a single hangtag or a hangtag group in which multiple hangtags are stacked and placed in an aligned through-hole manner. The hangtag may be moved by the rope pulling mechanism 3200 to a rope threading position corresponding to the rope feeding needle 3110.

The knotting kit 3330 is connected to the rotating driving member 3320. The knotting kit 3330 includes a pointed rotating chuck 3331. The rotating driving member 3320 is used to drive the rotating chuck 3331 to rotate. When the first driving assembly 3210 and / or the second driving assembly 3220 moves and drives the rope to move, the rope can be wound around the outer side of the rotating chuck 3320 as the rotating chuck 3320 rotates, and the rotating chuck 3320 can clamp the outer end of the rope loop as the rotating chuck rotates, and then the rope loop can be detached from the rotating chuck 3320, and the rotating chuck 3320 loosens the outer end of the loop as the rotating chuck 3320 rotates to form a knot. The rope loop can be detached from the rotating chuck 3320 by the third driving assembly 3310 driving the knotting kit 3330 to retreat.

[0075] Specifically, the rotary drive member 3320 includes a mounting seat 3321 and a motor 3322. The motor 3322 and the knotting kit 3330 are mounted on the mounting seat 3321. The motor 3322 is connected to a first gear 3323. The knotting kit 3330 is connected to a second gear 3332, a third gear 3333 and a fourth gear 3334. The second gear 3332 is meshed with the first gear 3323. The second gear 3332 is connected to the third gear 3333 in a circumferential linkage. The fourth gear 3334 is meshed with the third gear 3333. The fourth gear 3334 is connected to the rotating chuck 3331 in a circumferential linkage. Both the third gear 3333 and the fourth gear 3334 are bevel gears, which can change the direction of the rotating chuck 3331 relative to the first gear 3323.

[0076] Specifically, the first gear 3323 is connected with an inductive switch plate 3324, and the mounting seat 3321 is further provided with an inductive switch mounting bracket 3325 for cooperating with the inductive switch plate 3324. The inductive switch mounting bracket 3325 is used to mount an inductive switch, and the inductive switch is used to detect the rotation of the inductive switch plate 3324 and control the on and off of the motor 3322, so as to better control the rotation of the motor 3322 and the rotating chuck 3331 driven by the motor 3322.

[0077] Specifically, the knotting kit 3330 further includes a main body 3335 and a clamp tension switch 3336, wherein the clamp tension switch 3336 and the rotating clamp 3331 are rotatably connected to the main body 3335. The clamp tension switch 3336 includes a knob 3337 and a first protrusion 3338 connected to the knob 3337, wherein the first protrusion 3338 always abuts against one side of the rotating clamp 3336, for example, under the action of the elastic force provided by a spring, the first protrusion 3338 is pressed toward one side of the rotating clamp 3336. The end of the rotating clamp 3336 includes a second protrusion 3339, wherein the second protrusion 3339 is used to push the first protrusion 3338 to move and thereby rotate the knob 3337, and the rotating clamp 3336 is loosened or clamped as the knob 3336 rotates. For example, the knob 3336 and the two clamping blocks of the rotating chuck 3336 can be connected by a transmission connection such as a pawl, a ratchet, a cam, etc., and the second protrusion 3339 pushes the first protrusion 3338 each time, and the knob 3336 drives the pawl to slide. After the second protrusion 3339 is rotated and removed, the knob 3336 and the first protrusion 3338 can be restored to their original positions under the action of the spring force, so that the ratchet in or on the main body 3335 moves one grid, and the ratchet drives the cam circumferentially linked with it to rotate one grid, and the cam is adjacent to a clamping block of the rotating chuck 3336. The cam is alternately provided with protrusions and recesses on different grids, so that when it rotates to a certain grid, the protrusion of the cam can push one clamping block of the rotating chuck 3336 against another clamping block, thereby achieving the clamping of the rotating chuck 3336, and when it rotates to the next grid, the recess of the cam can release the force that pushes one clamping block of the rotating chuck 3336 against another clamping block, so that the two clamping blocks can be loosened, for example, under the action of the spring force. The structure for achieving loosening or clamping of the rotating chuck 3336 as the knob 3336 rotates is not limited to the above examples, as long as the two clamping blocks of the rotating chuck 3336 can be clamped or loosened when the knob 3336 completes one rotation and reset.
