Description

Technical Field

[0001] The utility model particularly relates to a self-adaptive water cup rack with self-locking function. Background Art

[0002] Cup holders for motorcycles, electric bikes, and other similar vehicles are fixed to the vehicle's body and are used to hold cups. While most cyclists carry a cup, the sizes and shapes of the cups vary. A small number of riders also carry various bottled beverages. However, there are currently no cup holders specifically designed for motorcycles, electric bikes, and the like.

[0003] To solve the above problems, the document with publication number "CN222682577U" discloses an automatic locking water cup holder, which includes a water cup main frame, an installation adapter plate, a spring, two fixed arms (a first fixed arm and a second fixed arm) and a movable plate. The installation adapter plate is installed on the water cup main frame, and the same end of the two fixed arms is rotatably connected to the water cup main frame through a spring, and the other end of the two fixed arms is rotatably connected to the movable plate.

[0004] This automatic locking cup holder has the following technical issues: Currently, soft-material milk tea cups are popular on the market. When these cups are placed in the cup holder, the movable plate, under the elastic force of the torsion spring (via the fixed arm), presses against the outer periphery of the cup, easily squeezing and deforming the cup body and causing the liquid in the cup to spill. Therefore, this cup holder is only suitable for "hard containers" and not "soft containers." Utility Model Content

[0005] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned existing technologies and provide an adaptive water cup holder with self-locking function. By adding a locking rod and a driving mechanism, the "self-locking" and "elastic clamping" states of the connecting arm can be switched, which is suitable for both hard water cups and soft water cups.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an adaptive cup holder with self-locking function, comprising a mounting frame and at least two groups of connecting arms, wherein the at least two groups of connecting arms are arranged in sequence along the axial direction of the mounting frame, one end of each group of connecting arms is rotatably connected to the mounting frame, and each group of connecting arms is linked to a first elastic member, and a cup bottom holder corresponding to the at least two groups of connecting arms and used to support the lower end of the water cup is provided below the mounting frame, characterized in that a locking rod and a driving mechanism linked to the locking rod are provided between the mounting frame and the connecting arm, the locking rod can be slidably set on the mounting frame or the connecting arm, and a card slot is provided on the connecting arm or the mounting frame, and the locking rod is inserted into or out of the card slot under the action of the driving mechanism.

[0007] Using this technical solution, when placing a soft cup, the connecting arm rotates until the locking rod is inserted into the slot, thereby locking the connecting arm and preventing the first elastic member from exerting continuous pressure on the connecting arm and causing deformation of the cup. Whether the locking rod is inserted or removed from the slot, the cup holder can accommodate hard cups. When the soft cup is to be clamped, the drive mechanism drives the locking rod to slide and insert into the slot on the connecting arm or mounting bracket, locking the connecting arm in its current position. At this point, the elastic force of the first elastic member no longer acts on the cup. The cup base also provides support for the lower end of the cup, ensuring overall clamping stability.

[0008] The above-mentioned adaptive cup holder with self-locking function can be further configured as follows: the mounting frame is provided with sliding holes distributed on the side of the connecting arm, the sliding holes are open toward the side of the connecting arm, the driving mechanism includes a second elastic member, the second elastic member and the locking rod are both arranged in the sliding hole, one end of the second elastic member abuts against one end of the locking rod, and the other end of the second elastic member abuts against the inner end of the sliding hole.

[0009] Using the above technical solution, when the soft cup body needs to be clamped, the connecting arm swings inward to the clamping position (i.e., the locking rod aligns with the slot) under the action of the first elastic member. At this time, the second elastic member (preferably a spring) pushes the locking rod along the sliding hole toward the side of the connecting arm due to its own elastic force. The end of the locking rod inserts into the slot on the connecting arm or mounting bracket, locking the connecting arm. The elastic force of the first elastic member no longer continuously acts on the cup body, and the clamping state is maintained only by the mechanical locking of the locking rod. This solves the problem of soft cup bodies being easily squeezed and deformed in the prior art. When the soft cup body needs to be removed or switched to a hard cup body for clamping, an external force is applied (such as manually moving the connecting arm) to overcome the elastic force of the second elastic member, causing the locking rod to move toward the inner end of the sliding hole and disengage the slot. The opening of the sliding hole is toward the side of the connecting arm. Once the locking rod aligns with the slot, it is ensured that the locking rod can be inserted into the slot.

[0010] The above-mentioned adaptive cup holder with self-locking function can be further configured as follows: the end of the connecting arm facing the mounting bracket is linked with an adapter block, the slot is arranged on the outer edge of the adapter block, the mounting bracket is provided with a rotating hole adapted to the adapter block, the driving mechanism also includes a pushing member distributed in the rotating hole, one end of the pushing member is rotatably connected to the mounting bracket, the sliding holes are distributed on the side of the rotating hole and the two are connected to each other, the end of the locking rod facing the rotating hole is provided with an inclined surface, and the adapter block is provided with a pushing block. When the connecting arm drives the adapter block to rotate in the rotating hole, the pushing block on the adapter block will drive the pushing member to rotate around the rotation point of the pushing member and the mounting bracket, and then the pushing member squeezes the locking rod through the inclined surface to exit the slot.

[0011] With the above technical solution, when the cup body needs to be removed, the connecting arm is pulled outward or rotated, and the connecting arm drives the adapter block at its end to rotate synchronously in the rotating hole of the mounting frame. During the rotation of the adapter block, the push block on it contacts the push member in the rotating hole and applies a thrust, driving the push member to rotate around the rotation point between it and the mounting frame toward the direction close to the locking rod. When the push member rotates, its other end contacts and continuously squeezes the inclined surface at the end of the locking rod. Due to the guiding effect of the inclined surface, the locking rod slides away from the adapter block (compressing the second elastic member), and finally the locking rod completely withdraws from the slot on the outer edge of the adapter block, releasing the lock on the connecting arm. After the quilt is removed, the connecting arm automatically resets under the action of the first elastic member. The rotation of the push member in the rotating hole is transmitted, and the swing of the connecting arm is directly converted into the withdrawal action of the locking rod. Unlocking can be completed without the need for additional external force intervention, which is convenient and quick.

[0012] The above-mentioned adaptive cup holder with self-locking function can be further configured as follows: the pushing member includes an annular body in an annular shape, a rotating groove arranged on the inner side of the annular body, a first opening is provided on the annular body, and the annular body is located on both sides of the first opening to form a first pushing point and a second pushing point. The rotating groove is distributed between the first pushing point and the second pushing point. A rotating positioning column is inserted into the rotating groove, and the rotating positioning column is fixed on the mounting frame. The pushing block on the adapter block drives the annular body to rotate around the rotating positioning column through the second pushing point, and then the first pushing point squeezes the locking rod out of the slot through the inclined surface.

[0013] Using this technical solution, when the connecting arm drives the adapter block to rotate within the rotating hole, the push block on the adapter block rotates synchronously with the adapter block. The push block pushes the second push point, driving the annular body to rotate around the rotating positioning column. The first push point squeezes the inclined surface of the locking rod, pushing the locking rod toward the inner end of the sliding hole (compressing the second elastic member) until the locking rod completely exits the slot on the outer edge of the adapter block, releasing the lock on the connecting arm. The first opening of the annular body forms symmetrical first and second push points. This not only reduces local pressure (reducing wear) by expanding the contact area of the two push points, but also utilizes the symmetry of the annular structure to ensure even force distribution during rotation, preventing the push member from becoming stuck due to unilateral force.

[0014] The above-mentioned adaptive cup holder with self-locking function can be further configured as follows: the rotating positioning column is eccentrically arranged in the rotating hole, and the rotating groove is arranged on the inner side of the annular body and distributed at one end close to the second pushing point, and there is a gap between the second pushing point and the inner circumference of the rotating hole.

[0015] With this technical solution, the rotational positioning post is eccentrically positioned within the rotational hole, altering the relative position of the rotational center of the pusher (annular body) and the center of the rotational hole. This ensures that when the pusher rotates about the eccentric axis, the trajectory of the first push point more closely matches the inclined surface of the locking rod, resulting in more complete force transmission. This prevents unlocking delays or locking rod jamming caused by trajectory deviation. The rotational groove is positioned closer to the second push point, shortening the distance between it and the rotational fulcrum (rotational positioning post). This reduces the need for manual force when pulling or rotating the connecting arm.

[0016] The above-mentioned adaptive cup holder with self-locking function may be further configured as follows: a second opening is provided on the side of the rotating groove.

[0017] The above technical solution facilitates the installation of the rotating positioning post into the rotating groove. At the same time, if there is a slight offset between the rotating positioning post and the rotating groove due to machining tolerances or long-term wear during the rotation of the pusher, the second opening can provide a certain amount of elastic deformation space to avoid jamming caused by rigid extrusion.

[0018] The above-mentioned adaptive cup holder with self-locking function can be further configured as follows: the sliding hole includes a first strip groove and a second strip groove arranged in sequence along the axial direction of the locking rod, the second strip groove is wider than the first strip groove, the locking rod can be slidably set in the first strip groove, and the end of the locking rod facing the second strip groove is provided with a stopper embedded in the second strip groove, and a slot is provided below the stopper, the second elastic member is installed in the second strip groove, and one end of the second elastic member is inserted into the slot.

[0019] With this technical solution, the block slides within the second slot (which is wider than the first), preventing the locking rod from extending beyond the sliding hole. This ensures a stable transition between the locking rod and the slot. A slot is provided below the block to prevent the elastic member from shifting or tilting during compression and rebound.

[0020] The above-mentioned adaptive cup holder with self-locking function can be further configured as follows: the mounting frame is connected to a cover plate corresponding to the side of the sliding hole, the cover plate is provided with a dovetail block on the side facing the mounting frame, the mounting frame is provided with a dovetail groove corresponding to the dovetail block and adapted to the dovetail block, an internal threaded hole is provided in the middle of the dovetail groove, the dovetail block is provided with a countersunk hole passing through the cover plate, and the internal threaded hole and the countersunk hole are connected by fasteners.

[0021] Using this technical solution, the cover plate can be removed to facilitate installation or removal of the second elastic member and locking rod. The dovetail block and dovetail groove provide a secure connection between the cover plate and the mounting bracket. Fasteners (preferably standard screws or bolts) in the countersunk and internally threaded holes ensure a strong connection between the cover plate and the mounting bracket while also preventing the fastener from protruding and affecting the appearance.

[0022] The above-mentioned adaptive cup holder with self-locking function can be further configured as follows: the mounting frame is provided with a set of rotating shafts corresponding to each set of connecting arms, the first elastic member includes a torsion spring, the torsion spring is sleeved on the outer circumference of the rotating shaft, the mounting frame is provided with a mounting cavity corresponding to the torsion spring, the end of the rotating shaft is inserted into the rotating hole and the end of the rotating shaft is linked to the adapter block, the outer circumference of the rotating shaft is provided with a clamping groove, and strip grooves are symmetrically provided on both sides of the mounting cavity, the outer arm of the torsion spring is pressed against the strip groove, and the inner arm of the torsion spring is pressed against the clamping groove.

[0023] Using this technical solution, pulling or turning the connecting arm causes the rotating shaft to rotate synchronously via the adapter block. This synchronous rotation of the adapter block, via a pusher, forces the locking rod out of the slot, releasing the lock. The torsion spring then drives the rotating shaft to continue rotating, returning the connecting arm to its initial position. The strip groove positions the outer arm of the torsion spring, preventing it from drifting left or right during operation. The coupling groove works in conjunction with the inner arm of the torsion spring, achieving linkage between the torsion spring and the rotating shaft.

[0024] The above-mentioned adaptive cup holder with self-locking function can be further configured as follows: the adaptive cup holder also includes a movable plate, if at least two groups of connecting arms are respectively rotatably connected to the movable plate.

[0025] With the above technical solution, if the connecting arms are linked together through the movable plate, when taking the cup, it is only necessary to pull or rotate the movable plate, which is easy to operate.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not 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 efforts are within the scope of protection of the present invention.

[0036] like Figures 1 to 7 The self-locking adaptive cup holder shown in the figure includes a mounting frame 1 and two sets of connecting arms 2, which are spaced apart axially along the mounting frame 1. One end of each set of connecting arms 2 is rotatably connected to the mounting frame 1, and each set of connecting arms 2 is linked to a torsion spring 3. Below the mounting frame 1, a cup holder 4 is provided, corresponding to the two sets of connecting arms 2 and used to support the lower end of a cup. Between the mounting frame 1 and the connecting arms 2, a locking rod 5 and a driving mechanism linked to the locking rod 5 are provided. The locking rod 5 is slidably mounted on the mounting frame 1 or the connecting arm 2. A slot 601 is provided on the connecting arm 2 or the mounting frame 1, and the locking rod 5 is inserted or removed from the slot 601 by the driving mechanism. Pulling the connecting arm 2 causes the locking rod 5 to rotate until it is inserted into the slot 601, thereby locking the connecting arm 2 and preventing the torsion spring 3 from continuously applying pressure to the connecting arm 2 and causing deformation of the cup body. Whether the locking rod 5 is inserted or removed from the slot 601, the cup holder can accommodate hard cups. When a soft cup needs to be clamped, the drive mechanism drives the locking rod 5 to slide and insert into the slot 601 on the connecting arm 2 or the mounting frame 1, locking the connecting arm 2 in its current position. At this time, the elastic force of the torsion spring 3 no longer acts continuously on the cup. The cup base 4 also provides support for the lower end of the cup to ensure overall clamping stability.

[0037] Mounting frame 1 is provided with sliding holes 101 located on the side of connecting arm 2. Sliding holes 101 are open toward the side of connecting arm 2. The driving mechanism includes a second elastic member 7. Both the second elastic member 7 and the locking rod 5 are disposed within sliding holes 101. One end of the second elastic member 7 abuts one end of the locking rod 5, while the other end abuts the inner end of sliding hole 101. When the soft cup is to be clamped, the connecting arm 2 swings inward under the action of the torsion spring 3 to a clamping position (where the locking rod 5 aligns with the locking slot 601). At this point, the elastic force of the second elastic member 7 (preferably a spring) pushes the locking rod 5 along the sliding holes 101 toward the side of the connecting arm 2. The end of the locking rod 5 then inserts into the locking slot 601 on the connecting arm 2 or mounting frame 1, locking the connecting arm 2. The elastic force of the torsion spring 3 no longer continuously acts on the cup, and the clamping state is maintained solely through the mechanical locking of the locking rod 5. This solves the problem of soft cups being easily squeezed and deformed in the prior art. When it is necessary to remove the soft cup body or switch to a hard cup body, an external force is applied (such as manually moving the connecting arm 2) to overcome the elastic force of the second elastic member 7, causing the locking rod 5 to move toward the inner end of the sliding hole 101 and disengage the locking slot 601. The opening of the sliding hole 101 faces the side of the connecting arm 2. Once the locking rod 5 aligns with the locking slot 601, it is ensured that the locking rod 5 can be inserted into the locking slot 601.

[0038] The sliding hole 101 includes a first strip groove 102 and a second strip groove 103 arranged in sequence along the axial direction of the locking rod 5. The second strip groove 103 is wider than the first strip groove 102. The locking rod 5 is slidably disposed within the first strip groove 102. A stopper 501 is provided at the end of the locking rod 5 facing the second strip groove 103, which engages within the second strip groove 103. A slot 502 is provided below the stopper 501. The second elastic member 7 is mounted within the second strip groove 103, with one end of the second elastic member 7 inserted into the slot 502. The stopper 501 slides within the second strip groove 103 (the second strip groove 103 is wider than the first strip groove 102), preventing the locking rod 5 from extending excessively out of the sliding hole 101. This ensures that the locking rod 5 and the engaging slot 601 can transition stably between the inserted and disengaged states. The slot 502 is provided below the stopper 501 to prevent the elastic member from shifting or tilting during compression and rebound.

[0039] The mounting frame 1 is connected to a cover plate 8 corresponding to the side of the sliding hole 101. A dovetail block 801 is provided on the side of the cover plate 8 facing the mounting frame 1. The mounting frame 1 is provided with a dovetail groove 104 corresponding to the dovetail block 801 and adapted to the dovetail block 801. An internal threaded hole 105 is provided in the middle of the dovetail groove 104. The dovetail block 801 is provided with a countersunk hole 802 that passes through the cover plate 8. The internal threaded hole 105 and the countersunk hole 802 are connected by fasteners. Removing the cover plate 8 facilitates the installation or removal of the second elastic member 7 and the locking rod 5. The "dovetail block 801 and dovetail groove 104" are provided to ensure a firm connection between the cover plate 8 and the mounting frame 1. The fasteners (preferably standard parts such as screws or bolts) connecting the countersunk hole 802 and the internal threaded hole 105 not only ensure the connection strength between the cover plate 8 and the mounting frame 1, but also prevent the fasteners from protruding and affecting the appearance through the countersunk structure.

[0040] The end of the connecting arm 2 facing the mounting frame 1 is linked to the adapter block 6, and the slot 601 is set on the outer edge of the adapter block 6. The mounting frame 1 is provided with a rotating hole 106 adapted to the adapter block 6. The driving mechanism also includes a pusher 9 distributed in the rotating hole 106. One end of the pusher 9 is rotatably connected to the mounting frame 1. The sliding hole 101 is distributed on the side of the rotating hole 106 and the two are connected to each other. The end of the locking rod 5 facing the rotating hole 106 is provided with an inclined surface 503. The adapter block 6 is provided with a pusher block 602. When the connecting arm 2 drives the adapter block 6 to rotate in the rotating hole 106, the pusher block 602 on the adapter block 6 drives the pusher 9 to rotate around the rotating point between the pusher 9 and the mounting frame 1, and then the pusher 9 squeezes the locking rod 5 out of the slot 601 through the inclined surface 503. When it is necessary to remove the cup body, the connecting arm 2 is pulled outward or rotated, and the connecting arm 2 drives the adapter block 6 at its end to rotate synchronously in the rotating hole 106 of the mounting frame 1. During the rotation of the adapter block 6, the push block 602 on it contacts the push member 9 in the rotating hole 106 and applies a thrust, driving the push member 9 to rotate around its rotation point with the mounting frame 1 toward the direction close to the locking rod 5. When the push member 9 rotates, its other end contacts and continuously squeezes the inclined surface 503 at the end of the locking rod 5. Due to the guiding effect of the inclined surface 503, the locking rod 5 slides away from the adapter block 6 (compressing the second elastic member 7). Finally, the locking rod 5 completely withdraws from the slot 601 on the outer edge of the adapter block 6, releasing the lock on the connecting arm 2. After the quilt is removed, the connecting arm 2 automatically resets under the action of the torsion spring 3. The rotation of the push member 9 in the rotating hole 106 is transmitted, directly converting the swing of the connecting arm 2 into the withdrawal action of the locking rod 5. Unlocking can be completed without the intervention of additional external force, which is convenient and quick.

[0041] The pusher 9 includes an annular body 901 and a rotation slot 902 disposed within the annular body 901. The annular body 901 has a first opening, with a first push point 903 and a second push point 904 formed on either side of the first opening. The rotation slot 902 is located between the first push point 903 and the second push point 904. A rotation positioning post 107 is inserted into the rotation slot 902. The rotation positioning post 107 is fixed to the mounting frame 1. The pusher 602 on the adapter block 6 drives the annular body 901 to rotate about the rotation positioning post 107 via the second push point 904. Subsequently, the first push point 903 squeezes the locking rod 5 out of the slot 601 via the inclined surface 503. When the connecting arm 2 drives the adapter block 6 to rotate within the rotation hole 106, the pusher 602 on the adapter block 6 rotates synchronously with the adapter block 6. The pusher 602 pushes the second push point 904, driving the annular body 901 to rotate about the rotation positioning post 107. The first push point 903 compresses the inclined surface 503 of the locking rod 5, pushing the locking rod 5 toward the inner end of the sliding hole 101 (compressing the second elastic member 7) until the locking rod 5 completely exits the locking groove 601 on the outer edge of the adapter block 6, thereby releasing the lock on the connecting arm 2. The first opening of the annular body 901 forms symmetrical first and second push points 904. This not only reduces local pressure (and wear) by expanding the contact area between the two push points, but also utilizes the symmetry of the annular structure to ensure even force distribution during rotation, preventing the push member 9 from becoming stuck due to unilateral force.

[0042] The rotation positioning post 107 is eccentrically positioned within the rotation hole 106, and the rotation slot 902 is located within the annular body, near the second push point 904. A gap exists between the second push point 904 and the inner circumference of the rotation hole 106. The eccentric positioning of the rotation positioning post 107 within the rotation hole 106 alters the relative position of the rotation center of the pusher 9 (annular body 901) and the center of the rotation hole 106. This ensures that when the pusher 9 rotates about the eccentric axis, the motion trajectory of the first push point 903 more closely aligns with the inclined surface 503 of the locking rod 5, resulting in more complete force transmission. This prevents unlocking delays or locking rod 5 jamming caused by trajectory deviation. The rotation slot 902 is positioned close to the second push point 904, shortening the distance between the second push point 904 and the rotation fulcrum (rotation positioning post 107). This reduces the need for manual force when pulling or rotating the connecting arm 2.

[0043] A second opening is provided on the side of the rotation slot 902 to facilitate the insertion of the rotation positioning post 107 into the rotation slot 902. Furthermore, if there is a slight misalignment between the rotation positioning post 107 and the rotation slot 902 during the rotation of the pusher 9 due to machining tolerances or long-term wear, the second opening provides space for elastic deformation, preventing jamming caused by rigid compression.

[0044] The mounting frame 1 is equipped with a set of rotating shafts 10 corresponding to each set of connecting arms 2. A torsion spring 3 is sleeved around the outer periphery of the rotating shafts 10. The mounting frame 1 has mounting cavities 108 corresponding to the torsion springs 3. The ends of the rotating shafts 10 are inserted into the rotation holes 106 and interlock with the adapter block 6. The outer periphery of the rotating shafts 10 is provided with engaging grooves 1001. Symmetrical strip grooves 109 are located on either side of the mounting cavity 108. The outer arms of the torsion springs 3 rest against the strip grooves 109, while the inner arms of the torsion springs 3 rest against the engaging grooves 1001. Pulling or rotating the connecting arm 2 causes the connecting arm 2 to rotate synchronously with the rotating shafts 10 through the adapter block 6. At this point, the adapter block 6 rotates synchronously and, through the pusher 9, drives the locking rod 5 out of the engaging groove 601, releasing the lock. The torsion spring 3 drives the rotating shaft 10 to continue rotating, returning the connecting arm 2 to its initial position. The strip grooves 109 position the outer arms of the torsion spring 3, preventing them from shifting left or right during operation. The engaging groove 1001 is linked with the inner arm of the torsion spring 3 to realize the linkage between the torsion spring 3 and the rotating shaft 10 .

[0045] The adaptive cup holder further comprises a movable plate 11. If the two sets of connecting arms 2 are respectively rotatably connected to the movable plate 11, the two sets of connecting arms 2 are linked by the movable plate 11. Therefore, when taking a cup, only the movable plate 11 needs to be pulled or rotated, which is convenient to operate.

[0046] The working principle of this embodiment is as follows:

[0047] When the cup is not in place, the locking rod 5 is not inserted into the slot 601, and the connecting arm 2 remains in the retracted position due to the action of the torsion spring 3. When a hard cup is placed in the cup, whether the connecting arm 2 is locked or unlocked has no effect on the cup, and the outer surface of the hard cup will not be deformed.

[0048] When you need to put in a soft water cup, push the movable plate 11 downward, or you can directly pull the connecting arm 2 downward. The connecting arm 2 drives the adapter block 6 to rotate until the slot 601 corresponds to the locking rod 5. Under the action of the second elastic member 7, the locking rod 5 will automatically insert into the slot 601. At this time, the connecting arm 2 is locked. When the soft water cup is put in, the movable plate 11 and the connecting arm 2 will not squeeze the soft water cup.

[0049] To unlock the lock, push the movable plate 11 downward, or simply pull the connecting arm 2 downward. The push block 602 will then drive the pusher 9 to rotate about the rotational positioning post 107 and, through the inclined surface 503, squeeze the locking rod 5 until the locking rod 5 exits the slot 601. It should be noted that at this point, the second push point 904 of the pusher 9 remains above the first strip groove 102 and resists the locking rod 5. When the user releases their grip, the connecting arm 2 automatically rotates in the opposite direction (upward) under the action of the torsion spring 3. During this process, even if the slot 601 aligns with the locking rod 5 (the second push point 904 resists the locking rod 5), the locking rod 5 will not extend into the slot 601, and the connecting arm 2 will be successfully reset. When connecting arm 2 returns to a position close to its final storage position, push block 602 on adapter block 6 rotates to second push point 904 and pushes second push point 904 back to its original position. This means that second push point 904 no longer blocks locking rod 5. Due to the resistance of adapter block 6's outer periphery, locking rod 5 will not extend out of first slot 102. (The locking rod 5 will only extend when connecting arm 2 rotates downward again until slot 601 aligns with locking rod 5. This state also corresponds to the action when placing a soft water cup.)
