Description

Technical Field

[0001] This invention relates to the field of water outlet devices, and more specifically to a water outlet device. Background Technology

[0002] In existing showerheads, the switching mechanism inside remains in the off-water position when the shower is turned off. However, since showerheads usually have a regular mode or a water-saving mode, if the switching mechanism remains in the off-water position when the showerhead is turned on again, the user will need to switch it to the regular mode or water-saving mode. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned defects or problems existing in the prior art or to provide a material basis for overcoming the aforementioned defects or problems existing in the prior art, and to provide a water outlet device.

[0004] To achieve the above objectives, the present invention and its preferred embodiments employ the following technical solutions, but the embodiments are not limited to the following solutions:

[0005] Option 1: A water outlet device, including...

[0006] The shell has a water outlet cavity, which has a water inlet hole, a water outlet hole and a water passage hole connecting the water inlet hole and the water outlet hole;

[0007] A switching component is slidably connected to the water outlet cavity to slide in a first direction to a first position and a second position. It is provided with a water passage hole and a flow regulating hole. The flow regulating hole is located on the side wall of the switching component and is adapted to connect the water passage hole and the water outlet hole. The switching component is adapted to slide to change the communication area between the flow regulating hole and the water outlet hole.

[0008] A biasing element, one end of which acts on the housing and the other end of which acts directly or indirectly on the switching element, applies a force to the switching element to cause it to slide toward a second position.

[0009] Option 2, based on Option 1, states that the connection area between the flow regulating hole and the water passage hole is smaller when the switching element is in the second position than when the switching element is in the first position.

[0010] Option 3, based on Option 1, the switching component is also adapted to slide in a third position, with the first, second, and third positions set sequentially along the first direction.

[0011] Option 4, based on Option 3, for the communication area between the flow regulating hole and the water passage hole, the switching component is smaller when it is in the second position than when it is in the first position, and the switching component is smaller when it is in the third position than when it is in the second position.

[0012] Option 5, based on Option 3, is that when the switching component slides to the third position, the flow regulating hole and the water passage hole are not connected or have the smallest connection area.

[0013] Option 6, based on Options 1 to 5, further includes a reset block. The two ends of the biasing member along the first direction act on the housing and the reset block respectively. The reset block is adapted to abut against the switching member to make the switching member slide to the second position. The reset block is adapted to slide along the first direction and away from the switching member under the action of water force when passing through water.

[0014] Option 7, based on Option 6, wherein the water passage extends through the switching member along the first direction, and its outlet end is adapted to point towards the reset block, so that water force applies force to the reset block, causing the reset block to slide along the first direction away from the switching member, and forming a water storage space between the reset block and the switching member.

[0015] Option 8, based on Option 6, includes an air cavity in the housing, a resetting block that is slidably sealed with the water outlet cavity to isolate the air cavity from the water outlet cavity, and a vent hole located on the outer wall of the housing; the biasing component is placed inside the air cavity.

[0016] Option 9, based on Option 6, further includes the switching component being adapted to slide in a third position. The first, second, and third positions are arranged sequentially along a first direction. The housing is provided with a first limiting surface, and the reset block is provided with a second limiting surface opposite to the first limiting surface. When the second limiting surface abuts against the first limiting surface, the reset block pushes the switching component to the second position.

[0017] Option 10, based on Option 9, includes an elastic claw on one of the reset block and the housing, and a limiting protrusion on the other. Therefore, one of the elastic claw and the limiting protrusion has a first limiting surface, and the other has a second limiting surface. The limiting protrusion is adapted to engage with the inclined surface of the elastic claw to open the elastic claw, and is adapted to return to its original position when the limiting protrusion enters the elastic claw, so that the first limiting surface and the second limiting surface are adapted to abut or move away from each other.

[0018] Option 11, based on Option 9, the housing includes a plug and a retaining ring. The plug has a sliding groove that opens in the direction of the switching element. The reset block is adapted to be inserted into the sliding groove through the opening of the sliding groove. The reset block protrudes radially to form the second limiting surface. The retaining ring is sleeved on the reset block and has a first limiting surface opposite to the second limiting surface. The retaining ring is fixedly connected to the plug.

[0019] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0020] 1. In Scheme 1 and its preferred embodiments, a water outlet device includes a housing, a switching component, and a biasing component.

[0021] The shell is provided with a water outlet cavity, which is provided with a water inlet, a water outlet and a water passage connecting the water inlet and the water outlet;

[0022] The switching element is slidably connected to the water outlet chamber to slide along a first direction to a first position and a second position. It is provided with a water passage hole and a flow regulating hole. The flow regulating hole is located on the side wall of the switching element and is adapted to connect the water passage hole and the water outlet hole to achieve side water outlet. This allows the switching element to slide and change the communication area between the flow regulating hole and the water outlet hole, thereby achieving stepless flow regulation. One end of the biasing element acts on the housing, and the other end acts directly or indirectly on the switching element to apply a force to the switching element, causing it to slide to the second position. This ensures that when the operating force on the switching element is released, the switching element returns to the second position for easy next use. The second position can be set to a regular mode or a water-saving mode for convenient operation.

[0023] 2. In Scheme 2 and its preferred embodiments, the connection area between the flow regulating hole and the water passage hole is smaller when the switching component is in the second position than when it is in the first position, so that it can be reset to the water-saving position, saving the user from frequently performing water-saving actions.

[0024] 3. In Scheme 3 and its preferred embodiment, the switching component is also adapted to slide in the third position. The first position, the second position and the third position are arranged sequentially along the first direction. When the switching component slides between the second position and the third position, it will not be affected by the biasing component. Thus, when the force on the switching component is released in this state, it will still be in this position, satisfying the water supply use and the next opening in this position.

[0025] 4. In Scheme 4 and its preferred embodiments, the communication area between the flow regulating hole and the water passage hole is smaller when the switching element is in the second position than when it is in the first position, thus allowing it to be reset to the water-saving position and saving the user from frequently performing water-saving actions. When the switching element is in the third position, it is smaller than when it is in the second position, and the third position is even more water-saving.

[0026] 5. In Scheme 5 and its preferred embodiments, when the switching component slides to the third position, the flow regulating hole and the water passage hole are not connected or the connection area is minimized, thereby realizing the water-stopping action or the throttling action.

[0027] 6. In Scheme 6 and its preferred embodiments, when the biasing element directly acts on the switching element, if the operating force on the switching element is released while the water is flowing, the switching element will slide to the second position under the action of the biasing element and will not be able to remain in the first position.

[0028] The biasing element acts on the housing and the reset block at both ends along the first direction. The reset block is adapted to abut against the switching element so that the switching element slides to the second position. The reset block is adapted to slide along the first direction away from the switching element under the action of water force when water flows through, so that the reset block will not push the switching element when water is flowing through, so that the position of the switching element can be maintained. Furthermore, when water is flowing through, the reset block disengages from the switching element, so that the switching element does not need to overcome the force of the biasing element when sliding, making the operation simpler.

[0029] 7. In Scheme 7 and its preferred embodiments, the water passage hole penetrates the switching member along the first direction, and its water outlet is adapted to point towards the reset block. The water force is large, so that the water force applies force to the reset block, causing the reset block to slide along the first direction and away from the switching member. When the switching member is in the first position and abuts against the reset block, the water can also apply force to the reset block, the position of the reset block is stable, and the use process is more stable.

[0030] A water storage space is formed between the reset block and the switching component, which allows water to be present at both ends of the switching component, reducing the impact of water force on the switching component and thus reducing the operating force.

[0031] 8. In Scheme 8 and its preferred embodiments, the housing is provided with an air cavity, and the reset block and the water outlet cavity are sealed and slidably fitted to isolate the air cavity and the water outlet cavity. The air cavity is provided with a vent hole located on the outer wall of the housing for exhaust and intake, so that the sliding of the reset block will not cause a vacuum phenomenon and prevent the sliding of the reset block from being obstructed. The biasing component is placed in the air cavity to reduce the influence of water on the biasing component and prevent the biasing component from rusting and aging when it is a spring.

[0032] 9. In Scheme 9 and its preferred embodiments, the housing is provided with a first limiting surface, and the reset block is provided with a second limiting surface opposite to the first limiting surface. When the second limiting surface abuts against the first limiting surface, the reset block pushes the switching member to the second position, so that the reset position of the switching member is determined, and the switching member will not be affected by the biasing member when sliding between the second position and the third position.

[0033] 10. In Scheme 10 and its preferred embodiments, one of the reset block and the housing is provided with an elastic claw, and the other is provided with a limiting protrusion. Therefore, one of the elastic claw and the limiting protrusion is provided with a first limiting surface, and the other is provided with a second limiting surface. The limiting protrusion is adapted to cooperate with the inclined surface of the elastic claw to open the elastic claw, and is adapted to return to its original position when the limiting protrusion enters the elastic claw, so that the first limiting surface and the second limiting surface are adapted to abut or move away from each other, so that the switching member is installed on the housing and is adapted to slide relative to the housing, and can be limited by the housing.

[0034] Option 11, based on Option 9, uses this structure to realize the first and second limiting surfaces, making the preparation of molds for the corresponding parts simpler. Attached Figure Description

[0058] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0059] refer to Figures 1-12 A water outlet device includes a housing 1, a switching component 2, a biasing component 3, and a reset block 4. In this embodiment, the water outlet device is a shower head, faucet, spray gun, aerator, etc. The following example uses a shower head as the water outlet device.

[0060] refer to Figure 2 The housing 1 includes a shower head body 11, a plug 12, a valve seat 13, and a threaded inner tube 14.

[0061] refer to Figure 1 The showerhead body 11 has water outlet holes 111. (Reference) Figure 3 , Figure 7 The plug 12 is installed in the handle portion of the shower head 11 by means of threaded connection or snap-fit ​​connection with the shower head body 11 or valve seat 13. The plug 12 has a connecting hole 121, the water outlet end of which communicates with the water outlet hole 111. The plug 12 also has elastic claws 122. In this embodiment, there are multiple elastic claws 122, and a sliding groove 123 is formed between each elastic claw 122. A first limiting surface 124 is formed on the inner side of the elastic claw 122, and the first limiting surface 124 faces the bottom of the sliding groove 123. (Reference) Figure 4 The valve seat 13 is installed inside the handle portion of the shower head body 11. A central hole is formed in the middle of the valve seat 13 along the first direction 5. The valve seat 13 is fitted over the plug 12, and a water passage hole 131 is provided on the inner wall of the valve seat 13. The valve seat 13 also has a water passage cavity 132, which connects the water passage hole 131 and the connecting hole 121. (Reference) Figure 7 The threaded inner tube 14 has a water inlet hole 141. Part of the threaded inner tube 14 is installed inside the handle portion of the shower head body 11, with the remaining portion protruding for threaded connection with the water pipe. The water inlet hole 141, the central hole of the valve seat 13, the water passage hole 131, the water passage cavity 132, the connecting hole 121, and the water outlet hole 111 are sequentially connected to form the water outlet cavity. (Reference) Figure 8 The plug 12 has an elastic claw 122 that prevents water from passing through, and is isolated by the reset block 4 to form an air cavity 15. The air cavity 15 is provided with a vent hole located on the outer wall of the housing 1 (not shown in the figure).

[0062] refer to Figure 12 The reset block 4 and the water outlet cavity are sealed and slidably fitted along the first direction 5 to isolate the air cavity 15 and the water outlet cavity. The sealing and sliding between the reset block 4 and the water outlet cavity can be achieved by the sealing ring on the reset block 4. The reset block 4 has a limiting protrusion 41 and a sliding post 42 connected to the limiting protrusion 41. The limiting protrusion 41 is generally spherical and has a second limiting surface 411, which faces the direction of the sliding post 42. The limiting protrusion 41 is adapted to cooperate with the inclined surface of the elastic claw 122, so that the elastic claw 122 is opened by force, so that the limiting protrusion 41 enters the sliding groove 123. Figure 7 , Figure 9 , Figure 11 When the limiting protrusion 41 enters the sliding groove 123 within the elastic claw 122, the limiting protrusion 41 disengages from the inclined surface engagement with the elastic claw 122, allowing the elastic claw 122 to recover. At this time, the first limiting surface 124 on the elastic claw 122 also resets accordingly (retracts towards the sliding post 42) and blocks the exit path of the limiting protrusion 41, thus making the first limiting surface 124 and the second limiting surface 411 opposite each other. Due to the effect of the biasing member 3 on the reset block 4, in the absence of water force, the reset block 4 will slide, causing the first limiting surface 124 and the second limiting surface 411 to approach each other until the first limiting surface 124 and the second limiting surface 411 abut against each other. At this time, the reset block 4 will no longer slide, thus achieving the stopping of the reset block 4. Here, the inclined surface engagement refers to at least one inclined surface or arc surface between the two engaging objects, so as to change the direction of the force. Furthermore, the reset block 4 is adapted to slide along the first direction 5 and away from the switching member 2 under the action of water force when passing through water, so that the limiting protrusion 41 slides towards the bottom of the sliding groove 123, so that the first limiting surface 124 and the second limiting surface 411 are moved away from each other. Of course, in other embodiments, the reset block 4 may be provided with an elastic claw 122, and the plug 12 may be provided with a limiting protrusion 41 to achieve the same effect.

[0063] refer to Figure 5 , Figure 7 , Figure 9 , Figure 11The switching element 2 is slidably connected to the outlet chamber to slide in a first position, a second position, and a third position along the first direction 5. The first position, the second position, and the third position are sequentially arranged along the first direction 5. In this embodiment, the switching element 2 is slidably connected to the central hole of the valve seat 13 along the first direction 5. The switching element 2 is provided with a water passage hole 21 and a flow regulating hole 22. The water passage hole 21 passes through the switching element 2 along the first direction 5. The water inlet end of the water passage hole 21 is connected to the water inlet hole 141, and the side outlet end of the water passage hole 21 is connected to the flow regulating hole 22. The outlet end of the water passage hole 21 in the first direction 5 is adapted to point towards the reset block 4, so that the water force applies force to the reset block 4, causing the reset block 4 to slide along the first direction 5 and away from the switching element 2. After the reset block 4 slides, a water storage space 16 is formed between the reset block 4 and the switching element 2, so that the water force on both ends of the switching element 2 is balanced. To facilitate the operation of the switching component 2, it can be operated through a push button exposed outside the housing 1. For example, the push button and the push button seat are limited to each other along the first direction 5, so that the push button can drive the push button seat to slide along the first direction 5. The push button seat and the switching component 2 are limited to each other along the first direction 5, so that the push button seat can drive the switching component 2 to slide along the first direction 5.

[0064] refer to Figure 7 , Figure 9 , Figure 11 The flow regulating hole 22 is located on the side wall of the switching member 2 and is adapted to connect the water passage hole 21 and the water flow hole 131. The flow regulating hole 22 is adapted to change the communication area between the flow regulating hole 22 and the water flow hole 131 by sliding. The communication area between the flow regulating hole 22 and the water flow hole 131 is smaller when the switching member 2 is in the second position than when it is in the first position, and smaller when the switching member 2 is in the third position than when it is in the second position. The flow regulating hole 22 and the water flow hole 131 are misaligned and sealed by the sealing ring when the switching member 2 is in the third position, and the flow regulating hole 22 and the water flow hole 131 are not connected, thereby achieving water stop.

[0065] refer to Figure 7 , Figure 9 , Figure 11 One end of the biasing member 3 acts on the housing 1, and the other end acts directly or indirectly on the switching member 2 to apply a force to the switching member 2, causing it to slide towards the second position. Direct action means there is no intermediate transmission between the biasing member 3 and the switching member 2. In this embodiment, for better performance, indirect action is used. Specifically, both ends of the biasing member 3 along the first direction 5 act on the housing 1 and the reset block 4, respectively. The reset block 4 is adapted to abut against the switching member 2, causing the switching member 2 to slide towards the second position until the second limiting surface 411 abuts against the first limiting surface 124, at which point the reset block 4 pushes the switching member 2 to the second position. The biasing member 3 can be a spring, rubber, magnetic material, etc. In this embodiment, the biasing member 3 is a spring and is sleeved on the elastic claw 122.

[0066] Of course, in other embodiments, when the reset block 4 is not present, the biasing member 3 can also act on the push button or push button seat fixedly connected to the switching member 2 to reset the switching member 2, as long as it can indirectly or directly reset the switching member 2. The biasing member 3 can be placed in an air cavity communicating with the outside air, or it can be located at the push button or push button seat.

[0067] When using, refer to Figure 7 , Figure 9 In the absence of water, if the switching element 2 slides between the first and second positions, the switching element 2 will push the reset block 4 to slide, and the biasing element 3 will store energy. When the operating force acting on the switching element 2 is released at this time, the biasing element 3 releases energy, and the reset block 4 pushes the switching element 2 until the first limiting surface 124 of the housing 1 and the second limiting surface 411 of the switching element 2 are in a limiting engagement, and the switching element 2 moves to the second position. Figure 9 As shown. Reference Figure 11 If the switching member 2 slides between the second and third positions, due to the limiting cooperation between the first limiting surface 124 of the housing 1 and the second limiting surface 411 of the switching member 2, the reset block 4 maintains the corresponding position under the action of the biasing member 3 and will not act on the switching member 2. The switching member 2 can slide freely and stop, and will not slide due to the action of the biasing member 3.

[0068] Under water flow conditions, refer to Figure 11 The reset block 4 slides away from the switching element 2 due to the hydraulic force within the water passage 21, forming a water storage space 16 between itself and the switching element 2. Therefore, the two ends of the switching element 2 are hydraulically balanced, reducing the switching force caused by the hydraulic force, and the biasing element 3 stores energy at this time. If the switching element 2 slides between the second and third positions, it can slide freely and stop. Since the connecting area between the water passage 131 and the flow regulating hole 22 is small at this time, the flow rate of the outlet hole 111 is small. If it slides towards the first position, since the reset block 4 has disengaged from the switching element 2, the switching element 2 does not need to overcome the resistance caused by the biasing element 3 when moving towards the first position. Furthermore, since the reset block 4 maintains its position under hydraulic force, even if the operating force on the switching element 2 is released at this time, the switching element 2 will not reset. Since the connecting area between the water passage 131 and the flow regulating hole 22 is large at this time, the flow rate of the outlet hole 111 is large. (Reference) Figure 9 When the water is turned off between the first and second positions, the water force acting on the reset block 4 disappears, the bias member 3 releases energy and drives the reset block 4 to slide, and when the reset block 4 contacts the switching member 2, it pushes the switching member 2 until the switching member 2 is in the second position.

[0069] Compared with the prior art, this embodiment has the following beneficial effects:

[0070] In one exemplary embodiment, a water outlet device includes a housing 1, a switching element 2, and a biasing element 3.

[0071] The shell 1 is provided with a water outlet cavity, which is provided with a water inlet 141, a water outlet 111 and a water passage 131 connecting the water inlet 141 and the water outlet 111;

[0072] The switching element 2 is slidably connected to the water outlet chamber to slide along the first direction 5 to a first position and a second position. It is provided with a water passage hole 21 and a flow regulating hole 22. The flow regulating hole 22 is located on the side wall of the switching element 2 and is adapted to connect the water passage hole 21 and the water passage hole 131 to achieve side water outlet. This allows the switching element 2 to slide to change the communication area between the flow regulating hole 22 and the water passage hole 131, thereby achieving stepless flow regulation. One end of the biasing element 3 acts on the housing 1, and the other end acts directly or indirectly on the switching element 2 to apply a force to the switching element 2 to slide to the second position. This allows the switching element 2 to return to the second position when the operating force on the switching element 2 is released, making it convenient for the next use. The second position can be set to the normal mode or the water-saving mode for convenient use.

[0073] In one exemplary embodiment, the communication area between the flow regulating hole 22 and the water passage hole 131 is smaller when the switching element 2 is in the second position than when it is in the first position, thereby allowing it to be reset to the water-saving position and saving the user from having to perform water-saving actions frequently.

[0074] In one exemplary embodiment, the switching member 2 is also adapted to slide in a third position. The first position, the second position and the third position are arranged sequentially along the first direction 5. When the switching member 2 slides between the second position and the third position, it will not be affected by the biasing member 3. Thus, when the force on the switching member 2 is released in this state, it will still be in this position, satisfying the water supply use and the next opening in this position.

[0075] In one exemplary embodiment, the communication area between the flow regulating hole 22 and the water passage hole 131 is smaller when the switching element 2 is in the second position than when it is in the first position, thus allowing it to be reset to a water-saving position and saving the user from having to perform frequent water-saving actions. When the switching element 2 is in the third position, it is smaller than when it is in the second position, and the third position is even more water-saving.

[0076] In one exemplary embodiment, when the switching member 2 slides to the third position, the flow regulating hole 22 and the water passage hole 131 are not connected or have the smallest connection area, thereby achieving water-stopping or water-saving action.

[0077] In one exemplary embodiment, when the biasing element 3 acts directly on the switching element 2, if the operating force on the switching element 2 is released while the water is flowing, the switching element 2 will slide to the second position under the action of the biasing element 3 and will not be able to remain in the first position.

[0078] The biasing element 3 acts on the housing 1 and the reset block 4 at both ends along the first direction 5. The reset block 4 is adapted to abut against the switching element 2 so that the switching element 2 slides to the second position. The reset block 4 is adapted to slide along the first direction 5 away from the switching element 2 under the action of water force when water flows through, so that the reset block 4 will not push the switching element 2 when water is flowing through, so that the position of the switching element 2 can be maintained. In addition, when water is flowing through, the reset block 4 disengages from the abutment of the switching element 2, so that the switching element 2 does not need to overcome the force of the biasing element 3 when sliding, making the operation simpler.

[0079] In one exemplary embodiment, the water passage 21 passes through the switching member 2 along the first direction 5, and its water outlet is adapted to point towards the reset block 4. The water force is large, so that the water force applies force to the reset block 4, causing the reset block 4 to slide along the first direction 5 and away from the switching member 2. When the switching member 2 is in the first position and abuts against the reset block 4, the water can also apply force to the reset block 4, making the position of the reset block 4 stable and the use process more stable.

[0080] A water storage space 16 is formed between the reset block 4 and the switching element 2, which allows water to be present at both ends of the switching element 2, reducing the impact of water force on the switching element 2 and thus reducing the operating force.

[0081] In one exemplary embodiment, the housing 1 is provided with an air cavity 15, and the reset block 4 is sealed and slidably engaged with the water outlet cavity to isolate the air cavity 15 and the water outlet cavity. The air cavity 15 is provided with a vent hole located on the outer wall of the housing 1 for exhaust and intake, so that the sliding of the reset block 4 will not cause a vacuum phenomenon and prevent the sliding of the reset block 4 from being obstructed. The biasing component 3 is placed in the air cavity 15 to reduce the influence of water on the biasing component 3 and prevent the biasing component 3 from rusting and aging when it is a spring.

[0082] In one exemplary embodiment, the housing 1 is provided with a first limiting surface 124, and the reset block 4 is provided with a second limiting surface 411 opposite to the first limiting surface 124. When the second limiting surface 411 abuts against the first limiting surface 124, the reset block 4 pushes the switching member 2 to the second position, so that the reset position of the switching member 2 is determined, and the switching member 2 will not be affected by the bias member 3 when sliding between the second position and the third position.

[0083] In one exemplary embodiment, one of the reset block 4 and the housing 1 is provided with an elastic claw 122, and the other is provided with a limiting protrusion 41. Therefore, one of the elastic claw 122 and the limiting protrusion 41 is provided with a first limiting surface 124, and the other is provided with a second limiting surface 411. The limiting protrusion 41 is adapted to cooperate with the inclined surface of the elastic claw 122 to open the elastic claw 122, and is adapted to return to its original position when the limiting protrusion 41 enters the elastic claw 122, so that the first limiting surface 124 and the second limiting surface 411 are adapted to abut or move away from each other, so that the switching member 2 is installed on the housing 1 and is adapted to slide relative to the housing 1, and can be limited by the housing 1.

[0084] Example 2

[0085] In this embodiment, the structure of the reset block 4 is different from that in Embodiment 1, and the limiting of the reset block 4 is also different from that in Embodiment 1.

[0086] refer to Figures 13-16 The housing 1 includes a plug 12 and a retaining ring 17. The plug 12 has a sliding groove 123, which opens towards the direction of the switching member 2. A first positioning post 125 is provided at the bottom of the sliding groove 123 for positioning the biasing member 3. The reset block 4 is adapted to be inserted into the sliding groove 123 through the opening of the sliding groove 123 and is provided with a second positioning post 43 for positioning the biasing member 3. The reset block 4 protrudes radially to form a second limiting surface 411.

[0087] The retaining ring 17 is sleeved on the reset block 4 and has a first limiting surface 124 opposite to the second limiting surface 411. The retaining ring 17 is fixed by engaging with the plug 12, but other methods can also be used to achieve the fixation.

[0088] The working principle of this embodiment is the same as that of Embodiment 1, and will not be described in detail here.

[0089] The structure of the corresponding parts in this solution is simpler to manufacture than the structure of the elastic chuck 122 mentioned above.

[0090] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
