Description

Technical Field

[0001] The invention relates to the field of household appliances, in particular to a single-arm hanging rack. Background Art

[0002] As a household product that every family must have, the convenience of using a hanger greatly affects people's experience. Existing hangers have a complex structure, are extremely inconvenient to use, and take up a large space, making them inconvenient to store. Moreover, the length of the hanging rods of many hangers is limited, which cannot meet people's needs for drying larger objects such as quilts, cotton-padded clothes or blankets. At present, the hangers on the market are mainly divided into hanging hangers, telescopic hangers and connecting rod hangers.

[0003] The hanging clothes hanger suspends the hanging rod in the air through a chain, which saves space to a certain extent. However, considering the load-bearing capacity and force uniformity of the hanging rod, the chain connection position usually cannot be close to the two ends of the hanging rod, so that the area of ​​the hanging rod for drying clothes is very small, and this type of clothes hanger cannot adjust the height of the hanging rod.

[0004] The telescopic clothes hanger controls the lifting of the hanging rod by pulling a rope. Although the lifting of the hanging rod can be controlled to find the most sunny height, the structure of this clothes hanger is relatively complicated and the steering switch needs to be adjusted manually, which is inconvenient to use.

[0005] Although the connecting rod type clothes hanger can control the lifting of the clothes hanger through the connecting rod, which is convenient for users to use, it uses multiple sets of connecting rods, has a complex structure, and occupies a large space.

[0006] The prior art provides a circulating self-locking hanger, including a hanger rod, a rotating arm, and a support, the rotating arm including 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 and a fork assembly, the housing is rotatably mounted 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 is fixedly mounted on the fork assembly, and the ratchet is arranged in the housing; the self-locking mechanism also includes a shaft, a shift block and a fork, the shaft is rotatably inserted in the housing, the shift block is fixedly mounted on one end of the shaft, the fork is fixedly mounted on the other end of the shaft, the fork matches the ratchet, the shift block abuts against the other end of the fork assembly as the housing rotates, when the shift block is in the first position, the rotating arm rotates clockwise, and when the shift block is in the second position, the rotating arm rotates counterclockwise. Although this technology realizes the retraction and release of the hanger and saves space, it has a single structure and a single function, and does not have a one-way damping mechanism to control the rotation of the rotating arm.

[0007] Therefore, it is necessary to design a single-arm bracket with various structures, various functions, easy use, damping effect when the rotating arm rotates downward, and telescopic hanging rod to adapt to various installation environments. Summary of the invention

[0092] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying 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 explicit 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 of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0093] Example 1

[0094] like Figures 1 to 3 As shown, a single-arm hanging rack includes a fixed part 110, a rotating part rotatably connected to the fixed part 110 at one end, and a drying part directly or indirectly connected to the other end of the rotating part. The fixed part 110 includes a fixed plate 111 and an ear plate 112 symmetrically arranged on one side of the fixed plate 111. The two ear plates 112 are respectively provided with first through holes for the two ends of the connecting column 160 to pass through. The connecting column 160 passes through the rotating part so that the rotating part rotates around the central axis of the connecting column 160, thereby adjusting the height of the drying part and being able to retract the drying part. The outer ends of the two ear plates 112 are both provided with second through holes, and the two second through holes are respectively used to accommodate the first connecting members passing through the connecting column 160 to fix the ear plate 112 to the connecting column 160. The fixed plate 111 is provided with a plurality of functional holes 1111, which are convenient for installing hanging baskets, hanging baskets, etc., and convenient for placing daily necessities such as clips. The fixing plate 111 is connected to the wall, cabinet or window through fastening screws or fastening bolts.

[0095] A steering adjustment mechanism is provided in the rotating part, and the steering adjustment mechanism includes a one-way damping mechanism 140, a ratchet mechanism, and a direction adjustment mechanism for controlling the meshing state of the ratchet mechanism. The steering adjustment mechanism can change the direction in which the rotating part can rotate as the rotating part rotates, and realizes a non-return function for the rotating part in the rising state. The rotating part is a swing arm 120 with one end arranged between the two ear plates 112, and the drying part is a telescopic rod 130 connected to the other end of the swing arm 120. It is worth noting that the swing arm 120 and the telescopic rod 130 can be provided as a split structure or an integrally formed structure.

[0096] In particular, such as Figure 1 to Figure 2 As shown, one end of the telescopic rod 130 is connected to the end of the swing arm 120 away from the fixed part 110, and the whole device is an L-shaped structure. Alternatively, the middle part of the telescopic rod 130 is sleeved on the end of the swing arm 120 away from the fixed part 110, and the whole device is a T-shaped structure.

[0097] Specifically, the ratchet mechanism includes a ratchet 150 and an engagement member that can be engaged with the ratchet 150, and the ratchet 150 is sleeved on the outer peripheral wall of the connecting column 160. The ratchet 150 and the connecting column 160 are fixedly connected or form an integrally formed structure. The direction adjustment mechanism can adjust the engagement state of the engagement member and the ratchet 150, and the rotatable direction of the rotating part can be changed by switching the engagement state between the ratchet 150 and the engagement member. In particular, the direction adjustment mechanism has a working high point and a working low point, and the working high point is used to change the current rotation 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 rotation direction of the rotating part to the opposite direction when the rotating part moves to the lowest point.

[0098] In this way, by connecting the fixed part 110 to the wall, cabinet or window, and setting a single swing arm 120 to rotate around the fixed part 110, the bottom end of the swing arm 120 is connected to the drying part, so that one end or both ends of the drying part can be freely adjusted in length, which is convenient for storing the swing arm 120 and the telescopic rod 130. In addition, the rotating part is provided with a ratchet mechanism and a direction adjustment mechanism, so that the swing arm 120 can swing up and down to adjust the drying height, and when swinging upward, due to the bite between the ratchet 150 and the meshing member, the swing arm 120 has a self-locking function and will not swing downward. When the swing arm 120 rotates to the highest point, the direction adjustment mechanism automatically adjusts the direction, so that the swing arm 120 can rotate freely downward, and when it rotates to the lowest point, the direction adjustment 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 swing arm 120 will not be too fast during the swinging process.

[0099] like Figures 4 to 7 As shown, in this embodiment, a receiving groove is provided on one side of the end of the swing arm 120 close to the ear plate 112, and the receiving groove is used to accommodate the steering adjustment mechanism, and a one-way damping mechanism 140 is provided at the notch of the receiving groove for the connection column 160 to pass through. In particular, the one-way damping mechanism 140 is fixedly connected to the swing arm 120 and can rotate around the connection column 160, so that the swing arm 120 is subjected to the one-way damping effect when rotating downward around the connection column 160.

[0100] Specifically, a first mounting plate 153 is provided at the notch of the receiving groove, and the first mounting plate 153 is adapted to the shape of the receiving groove to close the receiving groove. A snap ring 154 in an annular structure is provided on the first mounting plate 153, and a snap groove 1211 for accommodating the snap ring 154 is provided in the receiving groove. The snap ring 154 is connected with the snap groove 1211 by the matching connection, so that the first mounting plate 153 is connected with the receiving groove, and the first mounting plate 153 is not easy to be removed without damage.

[0101] The rear end surface of the swing arm 120 is covered with a second mounting plate 141, and the rear end surface of the second mounting plate 141 is covered with a mounting cover 143. The mounting cover 143 contains a one-way damper 142 sleeved on the outer peripheral wall of the connecting column 160. The second mounting plate 141 and the mounting cover 143 are clamped by a clamping structure, and the second mounting plate 141 and the swing arm 120 are fixedly connected by fasteners. The one-way damper 142 is arranged in an annular structure, and a plurality of damping grooves 1423 are arranged on its inner peripheral wall. A roller 1424 and a wedge 1425 are arranged in the damping groove 1423. The wedge 1425 is arranged in a Y-shaped structure to control the rolling direction of the roller 1424, so that when the swing arm 120 drives the one-way damper 142 to rotate upward, the one-way damper 142 and the connecting column 160 can rotate freely; when the swing arm 120 drives the one-way damper 142 to rotate downward, the one-way damper 142 and the connecting column 160 are subjected to the damping effect of the roller 1424, so that the swing arm 120 is subjected to the damping effect when swinging downward.

[0102] In particular, a sealing ring 1422 and a plurality of liquid storage grooves 1421 are provided on the rear end surface of the one-way damper 142. The liquid storage groove 1421 is provided in an annular structure and is used to store liquids such as lubricating oil. The sealing ring 1422 can ensure the sealing between the liquid storage groove 1421 and the mounting cover 143 to prevent leakage of lubricating oil. A plurality of liquid guide grooves 1431 are provided on the front end surface of the mounting cover 143. The liquid guide grooves 1431 are provided in an arc-shaped structure and are used to inject liquids such as lubricating oil.

[0103] like Figures 4 to 5 As shown, in this embodiment, the receiving groove includes an upper groove 121 and a lower groove 122 connected to each other, and the upper groove 121 and the lower groove 122 are both arranged in an annular 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 150, and a mounting hole for the connecting column 160 to pass through is arranged on the end surface of the upper groove 121, so that the swing arm 120 can rotate around the connecting column 160. The lower groove 122 accommodates the engagement member.

[0104] Specifically, a mounting shaft 171 is horizontally arranged in the lower groove 122, and one end of the mounting shaft 171 passes through the front end surface of the swing arm 120. The engaging member is a shifting tooth 172, and the shifting tooth 172 is arranged in a strip-shaped structure. The mounting shaft 171 is connected to the shifting tooth 172 to control the shifting tooth 172 to rotate back and forth in the lower groove 122.

[0105] The upper end surface of the shifting tooth 172 is provided with a ratchet tooth that can mesh with the ratchet wheel 150. The ratchet teeth at the left and right ends of the shifting tooth 172 are selectively meshed with the ratchet wheel 150 to change the direction in which the shifting tooth 172 can rotate around the ratchet wheel 150.

[0106] like Figures 8 to 9 See Figures 4 to 5 In this embodiment, a blocking column is provided on the front end surface of the ratchet 150, and the blocking column includes a first blocking column 151 and a second blocking column 152, and the angle between the first blocking column 151 and the second blocking column 152 is less than 360°. Preferably, the first blocking column 151 and the second blocking column 152 are respectively located at the uppermost end and the lowermost end of the front end surface of the ratchet 150. Since the angle between the first blocking column 151 and the second blocking column 152 is 360°, the maximum swingable angle of the swing arm 120 is less than 360°. The swing arm 120 can be rotated to a vertical state to be close to a wall, a window or a cabinet, which greatly saves space.

[0107] The end of the mounting shaft 171 away from the shifting tooth 172 passes through the front end surface of the swing arm 120, and the end of the mounting shaft 171 passing through the swing arm 120 is provided with a shifting fork 170. The shifting fork 170 is arranged in a peach-shaped structure with a smooth outer contour, and has a first end connected to the mounting shaft 171, and a second end that movably abuts against the first stop column 151 or the second stop column 152. The first end is fixedly connected to the mounting shaft 171, and the mounting shaft 171 is fixedly connected to the shifting tooth 172, so that the shifting fork 170 can drive the shifting tooth 172 to rotate accordingly. In particular, the second end movably abuts against a side of the first stop column 151 or the second stop column 152 close to the swing range of the swing arm 120, so as to always limit the second end within the swing range of the swing arm 120. When the shifting fork 170 rotates to contact with the first stop column 151, the first stop column 151 pushes the shifting fork 170 to rotate to the left. 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.

[0108] In this configuration, the swing arm 120 is at the lowest position, the shift fork 170 is located on the left side of the second stop column 152, and the second end of the shift fork 170 faces the left side. At this time, the ratchet teeth at the right end of the shift tooth 172 are meshed with the ratchet wheel 150, and the shift tooth 172 can only rotate in the clockwise direction due to the anti-return effect of the ratchet wheel 150. When the swing arm 120 swings to the highest point in the clockwise direction, the shift fork 170 contacts the first stop column 151, and the first stop column 151 pushes the shift fork 170 to rotate to the left. At this time, the shift fork 170 drives the shift tooth 172 to rotate to the right, and the ratchet teeth at the right end of the shift tooth 172 (the right end at this time refers to the right end of the shift tooth 172 when it rotates to the highest point with the swing arm 120) are meshed with the ratchet wheel 150, and the shift tooth 172 can only rotate in the counterclockwise direction due to the anti-return effect of the ratchet wheel 150. When the swing arm 120 swings counterclockwise to the lowest point, the shift fork 170 contacts the second stop post 152, and the second stop post 152 pushes the shift fork 170 to rotate leftward. At this time, the shift fork 170 drives the shift tooth 172 to rotate rightward, and the right end of the shift tooth 172 (the right end at this time refers to the right end of the shift tooth 172 when the swing arm 120 rotates to the lowest point) is meshed with the ratchet wheel 150, and the shift tooth 172 can only rotate clockwise due to the anti-return effect of the ratchet wheel 150.

[0109] like Fig.10 As 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 in the round tube 133. The square tube 132 and the round tube 133 slide relative to each other, thereby adjusting the length of the telescopic rod 130, so that the device can be applied to different installation sites. Both the square tube 132 and the round tube 133 are provided with positioning holes, and the positioning holes are used for fasteners to pass through to fix the square tube 132 and the round tube 133. The fasteners are preferably expansion bolts, which can be quickly disassembled and assembled.

[0110] In this embodiment, a plurality of elastic hooks are provided on the telescopic rod 130. The elastic hooks include an elastic ring sleeved on the outer peripheral wall of the telescopic rod and a hanging ring connected to the bottom end of the elastic ring. In particular, the elastic ring and the hanging ring are both 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. In this arrangement, 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 tightly engaged to ensure that the elastic hook will not be moved by wind.

[0111] The specific working method of this embodiment is described below:

[0112] When the swing arm 120 is at the lowest position and is in a retracted state, the shift fork 170 is located on the left side of the second stop column 152, and the second end of the shift fork 170 faces the left side. At this time, the right end of the shift tooth 172 is engaged with the ratchet 150. The swing arm 120 can only rotate in the clockwise direction around the connecting column 160. When the user pushes the swing arm 120 to rotate to a suitable position, the swing arm 120 can be automatically locked. When the swing arm 120 needs to be retracted, the user pushes the swing arm 120 to swing to the highest point in the clockwise direction, and the shift fork 170 contacts the first stop column 151, and the first stop column 151 pushes the shift fork 170 to rotate to the left. The shift fork 170 then drives the shift tooth 172 to rotate to the right, so that the right end of the shift tooth 172 (the right end here is the right end when the shift tooth 172 is at the highest point) is engaged with the ratchet 150. The swing arm 120 can rotate counterclockwise around the ratchet 150. When the swing arm 120 swings counterclockwise to the lowest point, the shift fork 170 contacts the second stop post 152, and the second stop post 152 pushes the shift fork 170 to rotate leftward. The shift fork 170 drives the shift tooth 172 to rotate rightward, so that the right end ratchet of the shift tooth 172 engages with the ratchet 150, and the device is in the retracted state.

[0113] Example 2

[0114] like Figures 11 to 12As shown, the structural principle of this embodiment is similar to that of the embodiment 1, and the difference from the embodiment 1 is that a baffle plate 280 is provided on the end surface of the connecting column 260 passing through the swing arm 220, and the baffle plate 280 is respectively provided with a first through hole for the first baffle column 251 to pass through, and a second through hole for the second baffle column to pass through, so as to fix the baffle plate 280 and the connecting column 260. An upper baffle plate 281 and a lower baffle plate 282 are provided on the rear end surface of the baffle plate 280, and the angle between the upper baffle plate 281 and the lower baffle plate 282 is less than 360°. Preferably, the upper baffle plate 281 and the lower baffle plate 282 are respectively located at the top and bottom ends of the baffle plate 280, so that the maximum swingable angle of the swing arm 220 is less than 360°. The upper baffle plate 281 and the lower baffle plate 282 are both located between the baffle plate 280 and the front end surface of the swing arm 220.

[0115] In this embodiment, a shift fork 270 is provided at one end of the mounting shaft 271 that passes through the swing arm 220. The shift fork 270 has a first end connected to the mounting shaft 271 and a second end that is movably opposed to the upper baffle 281 or the lower baffle 282. The second end is movably opposed to a side of the upper baffle 281 or the lower baffle 282 that is close to the swing range of the swing arm 220, and the second end is always located within the swing range of the swing arm 220. In particular, both upper and lower ends of the baffle 280 are close to the outer end of the shift fork 270 to ensure that the upper baffle 281 and the lower baffle 282 can act on the shift fork 270.

[0116] The working method of this embodiment is the same as that of embodiment 1, except that when the swing arm 220 rotates to the highest point, the fork 270 is acted upon by the upper baffle 281 and rotates to the left, and when the swing arm 220 rotates to the lowest point, the fork 270 is acted upon by the lower baffle 282 and rotates to the left.

[0117] Example 3

[0118] like Figures 13 to 15 As shown, the structural principle of this embodiment is similar to that of the embodiment 1, and the difference from the embodiment 1 is that the meshing member is a left shifting tooth 372 and a right shifting tooth 374 which are symmetrically arranged in the lower groove 322. The upper end surfaces of the left shifting tooth 372 and the right shifting tooth 374 are both provided with ratchets which can mesh with the ratchet 350 arranged in the upper groove 321. A pressing member 375 which can rotate left and right in the lower groove 322 is provided between the left shifting tooth 372 and the right shifting tooth 374, and the pressing member 375 is arranged in a fan-shaped structure. The lower part of the pressing member 375 rotates, and the upper part thereof movably contacts with the left shifting tooth 372 or the right shifting tooth 374, thereby controlling the left shifting tooth 372 or the right shifting tooth 374 to rotate outward.

[0119] Specifically, the bottom ends of the left shifting tooth 372 and the right shifting tooth 374 are both provided with a winding column, and the bottom end of the lower groove 322 is provided with a winding groove for accommodating the winding column, and the winding column can rotate left and right in the winding groove, so that the left shifting tooth 372 and the right shifting tooth 374 can rotate left and right in the lower groove 322. The side of the left shifting tooth 372 and the right shifting tooth 374 close to the inner peripheral wall of the lower groove 322 is provided with a compression spring 373 connected to the inner peripheral wall of the lower groove 322, and the restoring effect of the compression spring 373 can drive the left shifting tooth 372 and the right shifting tooth 374 to rotate inward, so as to drive the left shifting tooth 372 and the right shifting tooth 374 to engage with the ratchet 350.

[0120] In this way, since the pressing member 375 is arranged in a fan-shaped structure, when the pressing member 375 rotates to the right, the right side bevel of the pressing member 375 abuts against the left side straight side of the right shifting tooth 374, and the left side of the bottom of the pressing member 375 abuts against the right side of the left shifting tooth 372, so that the left shifting tooth 372 is away from the ratchet 350. At the same time, the compression spring 373 at the right shifting tooth 374 drives the right shifting tooth 374 to engage with the ratchet 350 under its reset action. The right shifting tooth 374 can rotate in the clockwise direction, and the ratchet 350 pushes the right shifting tooth 374 to deflect to the right when rotating. After the right shifting tooth 374 deflects to the right, the compression spring 373 on the right side is compressed, and the reset action of the compression spring 373 pushes the right shifting tooth 374 to deflect to the left, so that the right shifting tooth 374 continues to engage with the ratchet 350, ensuring that the right shifting tooth 374 can only rotate in the clockwise direction.

[0121] When the pressing member 375 rotates leftward, the working principle is opposite to that when the pressing member 375 rotates rightward.

[0122] like Fig.15As shown, in this embodiment, a blocking column is provided on the front end surface of the ratchet 350, and the blocking column includes a first blocking column 351 and a second blocking column 352, and the angle between the first blocking column 351 and the second blocking column 352 is less than 360°. Preferably, the first blocking column 351 and the second blocking column 352 are respectively located at the uppermost end and the lowermost end of the front end surface of the connecting plate. A rotating column 371 is provided at the front end of the pressure member 375, and the front end of the rotating column 371 passes through the swing arm 320, and a shift fork 370 is provided at one end of the rotating column 371 passing through the swing arm 320. The shift fork 370 can rotate left and right to drive the pressure member 375 to rotate through the rotating column 371. The shift fork 370 is arranged in a peach-shaped structure with a smooth outer contour, and has a first end connected to the rotating column 371, and a second end that is movably opposed to the first blocking column 351 or the second blocking column 352. The second end is movably opposed to the side of the first stopper 351 or the second stopper 352 close to the swing range of the swing arm 320, and the second end is always located within the swing range of the swing arm 320. When the shift fork 370 rotates to contact the first stopper 351, the first stopper 351 pushes the shift fork 370 to rotate leftward. When the shift fork 370 rotates downward to contact the second stopper 352, the second stopper 352 pushes the shift fork 370 to rotate leftward.

[0123] The specific working method of this embodiment is described below:

[0124] When the swing arm 320 is at the lowest position and is in a retracted state, the shift fork 370 is located on the left side of the second stop column 352, and the second end of the shift fork 370 faces the left side. At this time, the right shift tooth 374 is engaged with the ratchet 350. The swing arm 320 can only rotate in the clockwise direction around the connecting column 360. When the user pushes the swing arm 320 to rotate to a suitable position, the swing arm 320 can be automatically locked. When the swing arm 320 needs to be retracted, the user pushes the swing arm 320 to swing to the highest point in the clockwise direction, the shift fork 370 contacts the first stop column 351, and the first stop column 351 pushes the shift fork 370 to rotate to the left. The shift fork 370 then drives the pressing member 375 to rotate to the left, so that the right shift tooth 374 is away from the ratchet 350, and the return spring drives the left shift tooth 372 to engage with the ratchet 350. The swing arm 320 can rotate counterclockwise around the ratchet 350. When the swing arm 320 swings counterclockwise to the lowest point, the shift fork 370 contacts the second stop post 352, and the second stop post 352 pushes the shift fork 370 to rotate leftward. The shift fork 370 drives the left shift tooth 372 away from the ratchet 350, and the return spring drives the right shift tooth 374 to engage with the ratchet, and the device is in the retracted state.

[0125] Except for the above structure, the structural principle of this embodiment is the same as that of Embodiment 1 and Embodiment 2.

An upper baffle plate 481 and a lower baffle plate 482 are provided on the rear end surface of the baffle plate 480, and the angle between the upper baffle plate 481 and the lower baffle plate 482 is less than 360°. Preferably, an upper baffle plate 481 and a lower baffle plate 482 are respectively provided at the upper and lower ends of the rear end surface of the baffle plate 480. The upper baffle plate 481 and the lower baffle plate 482 are both located between the baffle plate 480 and the front end surface of the swing arm 420.

[0128] In this embodiment, a shift fork 470 is provided at one end of the rotating column that passes through the swing arm 420. The shift fork 470 has a first end connected to the rotating column and a second end that is movably opposed to the upper baffle 481 or the lower baffle 482. The second end is movably opposed to a side of the upper baffle 481 or the lower baffle 482 that is close to the swing range of the swing arm 420, and the second end is always located within the swing range of the swing arm 420. In particular, the upper and lower ends of the baffle 480 are close to the outer end of the shift fork 470 to ensure that the upper baffle 481 and the lower baffle 482 can act on the shift fork 470.

[0129] The working method of this embodiment is the same as that of embodiment 3, except that when the swing arm 420 rotates to the highest point, the fork 470 is acted upon by the upper baffle 481 and rotates to the left, and when the swing arm 420 rotates to the lowest point, the fork 470 is acted upon by the lower baffle 482 and rotates to the left.

A shift fork 570 is provided at the end of the mounting shaft 571 passing through the swing arm 520, and the shift fork 570 has a first end connected to the mounting shaft 571, and a second end that movably abuts against the upper end surface or the lower end surface of the retaining groove 561. The shift fork 570 rotates back and forth in the retaining groove 561, so that the maximum swingable angle of the swing arm 520 is less than 360°, and the second end is always located within the swing range of the swing arm 520.

[0133] The working method of this embodiment is the same as that of embodiment 1, the only difference is that when the swing arm 520 rotates to the highest point, the fork 570 is acted upon by the top end of the retaining groove 561 and rotates to the left, and when the swing arm 520 rotates to the lowest point, the fork 570 is acted upon by the bottom end of the retaining groove 561 and rotates to the left.

[0137] The working mode of this embodiment is the same as that of the first embodiment, and the only difference is that the shift fork 670 of this structure is arranged inside the swing arm 620, which enhances the aesthetics.

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