Description

Technical Field

[0001] The present invention relates to the field of household appliances, and particularly to a double-arm hanger. Background Art

[0002] As an essential household product in every family, the convenience of using a hanger greatly affects people's user experience. The existing hangers have a relatively complex structure, are extremely inconvenient to use, occupy a large space, and are not convenient for storage. Moreover, the length of the hanging rod of many hangers is limited and cannot meet people's needs for drying large items such as quilts, cotton-padded clothes, or blankets. Currently, the hangers on the market are mainly divided into hanging clothes hangers, telescopic clothes hangers, and link-type clothes hangers.

[0003] The hanging clothes hanger suspends the hanging rod in the air through a chain, saving space to a certain extent. However, considering issues such as the load-bearing of the hanging rod and the evenness of the force, the position where the chain is connected usually cannot be close to the two ends of the hanging rod, so that the area where the hanging rod can dry clothes is very small, and this kind of hanger cannot adjust the height of the hanging rod.

[0004] The telescopic clothes hanger controls the lifting of the hanging rod through a pull rope. Although it can control the lifting of the hanging rod to find the sunniest height, this kind of hanger has a relatively complex structure and requires manual adjustment of the steering switch, making it inconvenient to use.

[0005] Although the link-type clothes hanger can control the lifting of the hanger through links, making it convenient for users, it uses multiple groups of links, has a complex structure, and also occupies a large space.

[0006] The prior art provides a circulating self-locking hanger, including a hanging rod, a rotating arm, and a support. The rotating arm includes a self-locking mechanism. The rotating arm is connected to the support through the self-locking mechanism. The self-locking mechanism includes a housing, a ratchet wheel, and a fork assembly. The housing is rotatably installed on the fork assembly. One end of the fork assembly is fixedly connected to the support. The housing is fixedly connected to the rotating arm. The ratchet wheel is fixedly installed on the fork assembly. The ratchet wheel is arranged inside the housing. The self-locking mechanism further includes a shaft, a shifting block, and a fork. The shaft is rotatably inserted into the housing. The shifting block is fixedly installed at one end of the shaft. The fork is fixedly installed at the other end of the shaft. The fork matches the ratchet wheel. The shifting block abuts against the other end of the fork assembly as the housing rotates. When the shifting block is in the first position, the rotating arm rotates clockwise. When the shifting block is in the second position, the rotating arm rotates counterclockwise. Although this technology realizes the retraction and extension of the hanger and saves space, its structure is single, its function is single, and it does not have a one-way damping mechanism to control the rotation of the rotating arm.

[0007] Therefore, it is very necessary to design a double-arm hanger with diverse structures, diverse functions, convenient use, a damping effect when the rotating arm rotates downward, and a telescopic hanging rod to adapt to various installation environments. Summary of the Invention

[0008] To overcome the above problems, the present invention provides a double-arm hanger.

Detailed implementation manners

[0093] The following elaborates on the preferred embodiments of the present invention in conjunction with the attached drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0094] Embodiment 1

[0095] As Figures 1 to 4 shown, a double - arm hanger includes two fixing parts 110, rotating parts respectively arranged on one side of the two fixing parts 110, and a drying part with two ends directly or indirectly connected to the rotating parts. The rotating part is rotatably connected to the fixing part 110, and the rotating part rotates around the fixing part 110, so as to adjust the height of the drying part and be able to retract and extend the drying part.

[0096] A steering adjustment mechanism is arranged inside the rotating part. The steering adjustment mechanism includes a one - way damping mechanism 140, a ratchet mechanism and a direction - adjusting mechanism for controlling the meshing state of the ratchet mechanism. The steering adjustment mechanism can change the rotatable direction of the rotating part as the rotating part rotates, and realize the anti - reverse function for the rotating part in the rising state.

[0097] The ratchet mechanism includes a ratchet 150 and an engaging part that can be engaged with the ratchet 150. The direction - adjusting mechanism can adjust the meshing state between the engaging part and the ratchet 150 to adjust the rotating state of the rotating part. The direction - adjusting mechanism has a working high point and a working low point. The working high point is used to change the current rotating direction of the rotating part to the opposite direction when the rotating part moves to the highest point, and the working low point is used to change the current rotating direction of the rotating part to the opposite direction when the rotating part moves to the lowest point.

[0098] With such a setting, by respectively connecting the two fixing parts 110 to the wall body or the cabinet body or the window body, and setting the two rotating parts to rotate around the fixing parts 110, the bottom end of the rotating part is connected to the drying part, and the height of the drying part is adjusted by the rotation of the rotating part to retract and extend it. In addition, the rotating part is provided with a ratchet mechanism and a direction - adjusting mechanism, so that the rotating part can swing up and down to adjust the drying height, and due to the biting effect between the ratchet 150 and the engaging part when swinging upward, the rotating part has a self - locking function and will not swing downward. And when the rotating part rotates to the highest point, the direction - adjusting mechanism automatically adjusts the direction, so that the rotating part can freely rotate downward, and when rotating to the lowest point, the direction - adjusting mechanism automatically adjusts the direction to restore the initial state. In addition, the one - way damping mechanism 140 can ensure that the speed of the rotating part during the downward swing is not too fast.

[0099] It should be noted that the two fixing parts 110 are arranged parallel to each other or perpendicular to each other to select the most suitable installation structure according to the actual installation site, specifically including the following two structures:

[0100] As Figures 2 to 4As shown, in some embodiments, the fixing part 110 includes a fixing plate 111 and ear plates 112 symmetrically arranged on one side of the fixing plate 111. First through holes for both ends of the connecting shaft 163 to pass through are respectively provided on the two ear plates 112. The connecting shaft 163 passes through the rotating part to enable the rotating part to rotate around the central axis of the connecting shaft 163. Second through holes are respectively provided at the outer ends of the two ear plates 112, and the two second through holes are respectively used to accommodate the first connecting pieces 155 passing through the connecting shaft 163 to fix the ear plates 112 to the connecting shaft 163. A number of functional holes 1111 are provided on the fixing plate 111, and the functional holes 1111 facilitate the installation of hanging baskets, hanging baskets, etc., and are convenient for placing daily necessities such as clips. The fixing plate 111 is connected to the wall, cabinet or window through fastening screws or bolts.

[0101] The rotating part is a swing arm 120 with one end arranged between the two ear plates 112. An installation sleeve 141 is covered on one side of the swing arm 120. A connecting sleeve 143 for the connecting column 160 to pass through is provided on the end face of the installation sleeve 141 away from the swing arm 120, and the connecting sleeve 143 is connected to the installation sleeve 141 through a clamping structure. A clamping protrusion is circumferentially arranged on the end face of the connecting sleeve 143 close to the installation sleeve 141, and a clamping clip is circumferentially arranged on the rear end face of the installation sleeve 141. The clamping clip is cooperatively connected with the clamping protrusion to realize the quick disassembly and assembly of the installation sleeve 141 and the connecting sleeve 143. A one-way damper 142 sleeved on the outer peripheral wall of the connecting shaft 163 is accommodated in the connecting sleeve 143. When adopting this structure, the ratchet 150 is fixedly connected to the connecting shaft 163 or is integrally formed, and the connecting sleeve 143 and the one-way damper 142 can rotate around the central axis of the ratchet 150. Both ends of the connecting shaft 163 are fixedly connected to the ear plates 112. This installation method adopts an insertion connection between the internal structure of the swing arm 120 and the ear plates 112, which is convenient for disassembly and assembly. During work, the swing arm 120 rotates around the connecting shaft 163.

[0102] As Figures 5 to 6 shown, and refer to Figure 1, in some other embodiments, the fixing part 110 is a fixing plate 111. A fixing sleeve 144 is provided on one side of the fixing plate 111. A one-way damper 142 is sleeved on the outer peripheral side of the fixing sleeve 144, and a connecting sleeve 143 is sleeved on the outer peripheral side of the one-way damper 142. One end of the fixing sleeve 144 is connected to the fixing plate 111, and the other end is inserted into the connecting member 155. The sleeve hole of the fixing sleeve 144 is a square hole, a hexagonal hole or a hole of other shapes, and the shape of the connecting member 155 is adapted to the shape of the sleeve hole. A ratchet 150 is provided at one end of the connecting member 155 away from the connecting sleeve 143, and the ratchet 150 is fixedly connected to the connecting member 155 or is of an integrally formed structure. With this structure, the ratchet 150, the connecting member 155 and the fixing sleeve 144 are fixedly connected to each other and are fixedly connected to the fixing plate 111. The one-way damper 142 can rotate around the fixing sleeve 144, and the one-way damper 142 is fixedly connected to the connecting sleeve 143. The connecting sleeve 143 is connected to the mounting sleeve 141 provided on the swing arm 120 through a clamping structure, so as to realize the fixed connection of the swing arm 120, the mounting sleeve 141, the connecting sleeve 143 and the one-way damper 142 to form an integral body that can rotate around the ratchet 150. Particularly, a clamping protrusion is circumferentially provided on the end face of the connecting sleeve 143 close to the mounting sleeve 141, and a clamping clip is circumferentially provided on the rear end face of the mounting sleeve 141. The clamping clip is connected in cooperation with the clamping protrusion to realize the quick disassembly and assembly of the mounting sleeve 141 and the connecting sleeve 143.

[0103] As Figures 7 to 8 shown, specifically, the one-way damper 142 is arranged in an annular structure, and a plurality of damping grooves are provided on its inner peripheral wall. A roller 1423 and a wedge 1422 are arranged in the damping groove. The wedge 1422 is arranged in a Y-shaped structure to control the rolling direction of the roller 1423, so that when the swing arm 120 drives the one-way damper 142 to rotate upward, the one-way damper 142 can rotate freely with the fixing sleeve 144; when the swing arm 120 drives the one-way damper 142 to rotate downward, the one-way damper 142 is damped by the roller 1423 with the fixing sleeve 144, so that the swing arm 120 is damped when swinging downward.

[0104] Particularly, a first sealing ring 1421 is provided on the rear end face of the one-way damper 142 to realize the sealing between the one-way damper 142 and the connecting sleeve 143 and prevent the leakage of lubricating oil. A second sealing ring is provided at one end of the connecting sleeve 143 connected to the mounting sleeve 141, and a sealing ring mounting groove 1431 is provided at the front end of the connecting sleeve 143 to accommodate the second sealing ring.

[0105] The rear end of the connecting member 155 is provided with a mounting groove in the horizontal direction, and a ball 156 is provided on the upper end surface of the connecting member 155. Both the upper and lower ends of the ball 156 pass through the upper end surface of the connection. The mounting groove houses a connecting column 160, and the connecting column 160 passes through the connecting member 155 and the ratchet wheel 150. In particular, the axis of the connecting column 160 is collinear with the axis of the ratchet wheel 150. The connecting column 160 is arranged in a stepped structure and includes a large end and a small end connected end to end. The large end passes through the rotating part and can slide back and forth in the mounting groove for quick disassembly and assembly. A clamping groove 161 for accommodating the ball 156 is provided on the outer peripheral wall of the small end, and the connecting column 160 and the connecting member 155 are fixed through the cooperation of the ball 156 and the clamping groove 161. A mounting spring 162 is sleeved on the outer peripheral wall of the small end near the large end. With such a setting, when it is necessary to disassemble the connecting member 155, the connecting column 160 is pushed backward so that the ball 156 leaves the clamping groove 161, and the connection between the connecting member 155 and the connecting column 160 is released, realizing the quick disassembly and assembly of the device, which is convenient for the user and greatly saves the disassembly and assembly time of the device.

[0106] As Figures 6 to 7 shown, in this embodiment, the rotating part is a swing arm 120 that rotates around the connecting column 160, and the drying part is a telescopic rod 130 connected to the bottom end of the swing arm 120. A receiving groove is provided on one side of the top end of the swing arm 120. The receiving groove is used to accommodate the steering adjustment mechanism. An installation sleeve 141 is covered at the notch of the receiving groove, and a mounting plate 153 for the rear end of the connecting member 155 to pass through is covered on the rear end surface of the receiving groove. The mounting plate 153 is adapted to the shape of the receiving groove to close the receiving groove. A clamping ring 154 in a ring structure is provided on the mounting plate 153, and a clamping groove for accommodating the clamping ring 154 is provided in the receiving groove. Through the cooperation connection of the clamping ring 154 and the clamping groove 161, the mounting plate 153 and the receiving groove are connected, and it is not easy to disassemble the mounting plate 153 without damage.

[0107] As Figure 9 shown, in this embodiment, the receiving groove includes an upper groove 121 and a lower groove 122 connected up and down with each other. Both the upper groove 121 and the lower groove 122 are arranged in a ring structure, and the outer diameter of the upper groove 121 is larger than the outer diameter of the lower groove 122. The upper groove 121 is used to accommodate the ratchet wheel 150. A mounting hole for the ratchet wheel 150 to pass through is provided on the end surface of the upper groove 121 to realize the rotation of the swing arm 120 around the ratchet wheel 150. The front end of the connecting column 160 passes through the ratchet wheel 150 and is located outside the swing arm 120. The lower groove 122 houses a meshing member.

[0108] Specifically, an installation shaft 171 is horizontally arranged inside the lower slot 122, and one end of the installation shaft 171 passes through the front end face of the swing arm 120. The engaging member is a shifting tooth 172, and the shifting tooth 172 is arranged in a strip structure. The installation shaft 171 is connected to the shifting tooth 172 to control the back-and-forth rotation of the shifting tooth 172 inside the lower slot 122.

[0109] Ratchets are arranged on the upper end face of the shifting tooth 172 and can be engaged with the ratchet wheel 150. The ratchets at the left and right ends of the shifting tooth 172 are selectively engaged with the ratchet wheel 150 to change the rotatable direction of the shifting tooth 172 around the ratchet wheel 150.

[0110] As Figures 10 to 11 shown, and referring to Figures 5 to 6 , in this embodiment, a stop post is arranged on the front end face of the ratchet wheel 150. The stop post includes a first stop post 151 and a second stop post 152, and the included angle between the first stop post 151 and the second stop post 152 is less than 360°. Preferably, the first stop post 151 and the second stop post 152 are respectively located at the uppermost end and the lowermost end of the front end face of the ratchet wheel 150. Since the included angle between the first stop post 151 and the second stop post 152 is 360°, the maximum swing angle of the swing arm 120 is less than 360°. The swing arm 120 can rotate to a vertical state to closely adjoin a wall body, a window body or a cabinet body, greatly saving space.

[0111] The end of the installation shaft 171 far from the shifting tooth 172 passes through the front end face of the swing arm 120, and a shift fork 170 is arranged at the end of the installation shaft 171 passing through the swing arm 120. The shift fork 170 is arranged in a peach-shaped structure with a smooth outer contour and has a first end connected to the installation shaft 171 and a second end movably abutted against the first stop post 151 or the second stop post 152. The first end is fixedly connected to the installation shaft 171, and the installation shaft 171 is fixedly connected to the shifting tooth 172, so that the shift fork 170 can drive the shifting tooth 172 to rotate therewith. Specifically, the second end is movably abutted against the side of the first stop post 151 or the second stop post 152 close to the swing range of the swing arm 120 to always limit the second end within the swing range of the swing arm 120. When the shift fork 170 rotates to contact the first stop post 151, the first stop post 151 pushes the shift fork 170 to rotate leftward. When the shift fork 170 rotates downward to contact the second stop post 152, the second stop post 152 pushes the shift fork 170 to rotate leftward.

[0112] With such a setting, the swing arm 120 is at the lowest position, the fork 170 is located on the left side of the second stop post 152, and the second end of the fork 170 faces the left side. At this time, the right-end ratchet teeth of the tooth-picking part 172 are engaged with the ratchet wheel 150, and the tooth-picking part 172 can only rotate in the clockwise direction under the reverse-stop action of the ratchet wheel 150. When the swing arm 120 swings clockwise to the highest point, the fork 170 contacts the first stop post 151, and the first stop post 151 pushes the fork 170 to rotate leftward. At this time, the fork 170 drives the tooth-picking part 172 to rotate rightward, and the right-end (the right end here refers to the right end of the tooth-picking part 172 when it rotates with the swing arm 120 to the highest point) ratchet teeth of the tooth-picking part 172 are engaged with the ratchet wheel 150, and the tooth-picking part 172 can only rotate in the counterclockwise direction under the reverse-stop action of the ratchet wheel 150. When the swing arm 120 swings counterclockwise to the lowest point, the fork 170 contacts the second stop post 152, and the second stop post 152 pushes the fork 170 to rotate leftward. At this time, the fork 170 drives the tooth-picking part 172 to rotate rightward, and the right-end (the right end here refers to the right end of the tooth-picking part 172 when it rotates with the swing arm 120 to the lowest point) ratchet teeth of the tooth-picking part 172 are engaged with the ratchet wheel 150, and the tooth-picking part 172 can only rotate in the clockwise direction under the reverse-stop action of the ratchet wheel 150.

[0113] As Figure 12 shown, in this embodiment, the telescopic rod 130 includes a support 131, a square tube 132 and a round tube 133. The upper end of the support 131 is connected to the bottom end of the swing arm 120. A square hole is provided on one side of the support 131 for accommodating the square tube 132, and the square tube 132 is sleeved inside the round tube 133. The square tube 132 and the round tube 133 slide relative to each other, so as to adjust the length of the telescopic rod 130, so that the device can be applicable to different installation sites. Positioning holes are provided on both the square tube 132 and the round tube 133 for fasteners to pass through to fix the square tube 132 and the round tube 133. The fastener is preferably an expansion bolt, which can be quickly disassembled and assembled.

[0114] In this embodiment, a plurality of elastic hooks are provided on the telescopic rod 130. The elastic hook includes an elastic ring sleeved on the outer peripheral wall of the telescopic rod 130 and a hanging ring connected to the bottom end of the elastic ring. In particular, both the elastic ring and the hanging ring are arranged in a circular ring structure. The elastic ring and the hanging ring can be arranged in the same plane, or respectively arranged in planes perpendicular to each other. With such a setting, the elastic hook and the telescopic rod 130 can be quickly disassembled and assembled, and the elastic hook and the telescopic rod 130 can be closely joined to ensure that the elastic hook will not be affected by the wind and move.

[0115] The following describes the specific working mode of this embodiment:

[0116] When the swing arm 120 is in the lowest position and in the retracted state, the fork 170 is located on the left side of the second stop post 152, and the second end of the fork 170 faces the left side. At this time, the right end of the shifting tooth 172 meshes with the ratchet wheel 150. The swing arm 120 can only rotate clockwise around the connecting post 160. When the user pushes the swing arm 120 to rotate to an appropriate position, the swing arm 120 can be automatically locked. When it is necessary to retract the swing arm 120, the user pushes the swing arm 120 to swing clockwise to the highest point, and the fork 170 contacts the first stop post 151. The first stop post 151 pushes the fork 170 to rotate leftward. The fork 170 then drives the shifting tooth 172 to rotate rightward, so that the right end of the shifting tooth 172 (the right end here is the right end of the shifting tooth 172 when it is at the highest point) meshes with the ratchet wheel 150. The swing arm 120 can rotate counterclockwise around the ratchet wheel 150. When the swing arm 120 swings counterclockwise to the lowest point, the fork 170 contacts the second stop post 152. The second stop post 152 pushes the fork 170 to rotate leftward. The fork 170 drives the shifting tooth 172 to rotate rightward, so that the right end of the shifting tooth 172 meshes with the ratchet teeth, and the device is in the retracted state.

[0117] Embodiment 2

[0118] As Figures 13 to 14 shown, the structural principle of this embodiment is similar to that of Embodiment 1. The difference from Embodiment 1 is that a baffle 280 is covered on the end face of one end of the ratchet wheel 250 passing through the swing arm 220. The baffle 280 is respectively provided with a first through hole for the first stop post 251 to pass through and a second through hole for the second stop post to pass through, so as to fixedly connect the baffle 280 and the ratchet wheel 250. An upper retaining piece 281 and a lower retaining piece 282 are arranged on the rear end face of the baffle 280. The included angle between the upper retaining piece 281 and the lower retaining piece 282 is less than 360°. Preferably, the upper retaining piece 281 and the lower retaining piece 282 are respectively located at the top end and the bottom end of the baffle 280, so that the maximum swing angle of the swing arm 220 is less than 360°. Both the upper retaining piece 281 and the lower retaining piece 282 are located between the baffle 280 and the front end face of the swing arm 220.

[0119] In this embodiment, a fork 270 is arranged at one end of the mounting shaft 271 passing through the swing arm 220. The fork 270 has a first end connected to the mounting shaft 271 and a second end that is movably abutted against the upper retaining piece 281 or the lower retaining piece 282. The second end is movably abutted against the side of the upper retaining piece 281 or the lower retaining piece 282 close to the swing range of the swing arm 220, and the second end is always within the swing range of the swing arm 220. In particular, both the upper and lower ends of the baffle 280 are close to the outer end of the fork 270 to ensure that the upper retaining piece 281 and the lower retaining piece 282 can act on the fork 270.

[0120] The working mode of this embodiment is the same as that of Embodiment 1. The difference is only that when the swing arm 220 rotates to the highest point, the fork 270 rotates leftward under the action of the upper stop piece 281, and when the swing arm 220 rotates to the lowest point, the fork 270 rotates leftward under the action of the lower stop piece 282.

[0121] Embodiment 3

[0122] As Figures 15 to 17 shown, the structural principle of this embodiment is similar to that of Embodiment 1. The difference from Embodiment 1 is that the engaging members are the left shift tooth 372 and the right shift tooth 374 which are symmetrically arranged left and right in the lower groove 322. The upper end faces of the left shift tooth 372 and the right shift tooth 374 are both provided with ratchet teeth that can engage with the ratchet 350 arranged in the upper groove 321. A pressing member 375 that can rotate left and right in the lower groove 322 is arranged between the left shift tooth 372 and the right shift tooth 374. The pressing member 375 is arranged in a fan-shaped structure. The lower part of the pressing member 375 rotates, and its upper part is movably abutted against the left shift tooth 372 or the right shift tooth 374, so as to control the left shift tooth 372 or the right shift tooth 374 to rotate outward.

[0123] Specifically, the bottom ends of the left shift tooth 372 and the right shift tooth 374 are both provided with winding columns, and the bottom end of the lower groove 322 is provided with a winding groove for accommodating the winding columns. The winding columns can rotate left and right in the winding groove, so that the left shift tooth 372 and the right shift tooth 374 can rotate left and right in the lower groove 322. Compression springs 373 connected to the inner peripheral wall of the lower groove 322 are arranged on one side of the left shift tooth 372 and the right shift tooth 374 close to the inner peripheral wall of the lower groove 322. The reset action of the compression springs 373 can drive the left shift tooth 372 and the right shift tooth 374 to rotate inward, so as to drive the left shift tooth 372 and the right shift tooth 374 to engage with the ratchet 350.

[0124] With such a setting, since the pressing member 375 is arranged in a fan-shaped structure, when the pressing member 375 rotates rightward, the right hypotenuse of the pressing member 375 abuts against the left straight edge of the right shift tooth 374, and the left side of the bottom of the pressing member 375 abuts against the right side of the left shift tooth 372, so that the left shift tooth 372 is away from the ratchet 350. At the same time, the compression spring 373 at the right shift tooth 374 is driven by its reset action to drive the right shift tooth 374 to engage with the ratchet 350. The right shift tooth 374 can rotate in the clockwise direction, and when rotating, the ratchet 350 pushes the right shift tooth 374 to deflect rightward. After the right shift tooth 374 deflects rightward, the compression spring 373 on the right side is compressed, and the reset action of the compression spring 373 pushes the right shift tooth 374 to deflect leftward, so that the right shift tooth 374 continues to engage with the ratchet 350, ensuring that the right shift tooth 374 can only rotate in the clockwise direction.

[0125] When the pressing member 375 rotates leftward, the working principle is opposite to that when the pressing member 375 rotates rightward.

[0126] As Figures 14 to 16 shown, in this embodiment, a stop post is provided on the front end face of the ratchet wheel 350. The stop post includes a first stop post 351 and a second stop post 352, and the included angle between the first stop post 351 and the second stop post 352 is less than 360°. Preferably, the first stop post 351 and the second stop post 352 are respectively located at the uppermost end and the lowermost end of the front end face of the connecting plate. A rotating post 371 is provided at the front end of the pressing member 375. The front end of the rotating post 371 passes through the swing arm 320, and a fork 370 is provided at the end of the rotating post 371 passing through the swing arm 320. The fork 370 can rotate left and right to drive the pressing member 375 to rotate through the rotating post 371. The fork 370 is arranged in a peach-shaped structure with a smooth outer contour, and has a first end connected to the rotating post 371 and a second end that is movably abutted against the first stop post 351 or the second stop post 352. The second end is movably abutted against the side of the first stop post 351 or the second stop post 352 close to the swing range of the swing arm 320, and the second end is always within the swing range of the swing arm 320. When the fork 370 rotates to contact the first stop post 351, the first stop post 351 pushes the fork 370 to rotate left. When the fork 370 rotates downward to contact the second stop post 352, the second stop post 352 pushes the fork 370 to rotate left.

[0127] The following describes the specific working mode of this embodiment:

[0128] When the swing arm 320 is in the lowest position and in the retracted state, the fork 370 is located on the left side of the second stop post 352, and the second end of the fork 370 faces left. At this time, the right pawl 374 meshes with the ratchet wheel 350. The swing arm 320 can only rotate clockwise around the ratchet wheel 350. When the user pushes the swing arm 320 to rotate to an appropriate position, the swing arm 320 can be automatically locked. When it is necessary to retract the swing arm 320, the user pushes the swing arm 320 to swing clockwise to the highest point. The fork 370 contacts the first stop post 351, and the first stop post 351 pushes the fork 370 to rotate left. The fork 370 further drives the pressing member 375 to rotate left, so that the right pawl 374 moves away from the ratchet wheel 350, and the return spring drives the left pawl 372 to mesh with the ratchet wheel 350. The swing arm 320 can rotate counterclockwise around the ratchet wheel 350. When the swing arm 320 swings counterclockwise to the lowest point, the fork 370 contacts the second stop post 352, and the second stop post 352 pushes the fork 370 to rotate left. The fork 370 drives the left pawl 372 away from the ratchet wheel 350, and the return spring drives the right pawl 374 to mesh with the ratchet teeth, and the device is in the retracted state.

[0129] Except for the above structure, the structural principle of this embodiment is the same as that of the embodiments.

[0130] Embodiment 4

[0131] AsFigures 18 to 19 As shown, the structural principle of this embodiment is similar to that of Embodiment 2 and Embodiment 3. The difference from Embodiment 2 and Embodiment 3 is that a baffle 480 is provided on the end face of one end of the ratchet 450 passing through the swing arm 420. A first through hole for the first stop post 451 to pass through and a second through hole for the second stop post 452 to pass through are respectively provided on the baffle 480 to fixedly connect the baffle 480 with the connecting member. An upper stop piece 481 and a lower stop piece 482 are provided on the rear end face of the baffle 480, and the included angle between the upper stop piece 481 and the lower stop piece 482 is less than 360°. Preferably, the upper stop piece 481 and the lower stop piece 482 are respectively provided at the upper and lower ends of the rear end face of the baffle 480. Both the upper stop piece 481 and the lower stop piece 482 are located between the baffle 480 and the front end face of the swing arm 420.

[0132] In this embodiment, a fork 470 is provided at one end of the rotating column passing through the swing arm 420. The fork 470 has a first end connected to the rotating column and a second end that movably abuts against the upper stop piece 481 or the lower stop piece 482. The second end movably abuts against the side of the upper stop piece 481 or the lower stop piece 482 close to the swing range of the swing arm 420, and the second end is always within the swing range of the swing arm 420. In particular, both the upper and lower ends of the baffle 480 are close to the outer end of the fork 470 to ensure that the upper stop piece 481 and the lower stop piece 482 can act on the fork 470.

[0133] The working mode of this embodiment is the same as that of Embodiment 3. The difference is only that when the swing arm 420 rotates to the highest point, the fork 470 rotates to the left under the action of the upper stop piece 481, and when the swing arm 420 rotates to the lowest point, the fork 470 rotates to the left under the action of the lower stop piece 482.

[0134] Except for the above structure, the structural principle of this embodiment is the same as that of Embodiment 2 and Embodiment 3.

[0135] Embodiment 5

[0136] As Figure 20 shown, the structural principle of this embodiment is similar to that of Embodiment 1. The difference from Embodiment 1 is that a retaining groove 561 is provided on the outer peripheral wall of one end of the ratchet 550 passing through the swing arm 520. The retaining groove 561 is arranged in an arc structure, and the central angle of the arc of the retaining groove 561 is less than 360°. A fork 570 is provided at one end of the mounting shaft 571 passing through the swing arm 520. The fork 570 has a first end connected to the mounting shaft 571 and a second end that movably abuts against the upper end face or the lower end face of the retaining groove 561. The fork 570 rotates back and forth in the retaining groove 561, so that the maximum swing angle of the swing arm 520 is less than 360°, and the second end is always within the swing range of the swing arm 520.

[0137] The working mode of this embodiment is the same as that of Embodiment 1. The difference is only that when the swing arm 520 rotates to the highest point, the fork 570 rotates leftward under the action of the top end of the blocking groove 561, and when the swing arm 520 rotates to the lowest point, the fork 570 rotates leftward under the action of the bottom end of the blocking groove 561.

[0138] Except for the above structure, the structural principle of this embodiment is the same as that of Embodiment 1.

[0139] Embodiment 6

[0140] As Figures 21 to 22 shown, the structural principle of this embodiment is similar to that of Embodiment 1. The difference from Embodiment 1 is that a blocking post is provided on the rear end face of the ratchet wheel 650. The blocking post includes a first blocking post 651 and a second blocking post 652, and the included angle between the first blocking post 651 and the second blocking post 652 is less than 360°. The rear end of the mounting shaft 671 passes through the tooth-picking part 672 and is provided with a fork 670. The fork 670 has a first end connected to the mounting shaft 671 and a second end that is movably abutted against the first blocking post 651 or the second blocking post 652. The maximum swing angle of the swing arm 620 is less than 360°. The second end is movably abutted against the side of the first blocking post 651 or the second blocking post 652 close to the swing range of the swing arm 620, and the second end is always within the swing range of the swing arm 620.
