Description

Technical Field

[0001] The present invention relates to a rotary locking and positioning structure for a lock, and more particularly to a structure that allows the drive shaft, the inner lining, and the rotary shaft to be pre-assembled and positioned, so that when installed on a door body, the lock rod and the transmission column configured at the other end of the rotary handle can be directly connected to the inner lining and the rotary shaft, without the need to rotate the inner lining and the rotary shaft to align them with the lock rod and the transmission column, thereby improving the convenience and efficiency during assembly. Background Art

[0002] Doors are essential components of buildings, used for opening and closing to allow users to enter and exit. There are many types of doors, which will have different materials, sizes, and thicknesses according to different usage requirements. Generally, doors need to be equipped with locks to achieve the effects of opening and closing and anti-theft.

[0003] Generally speaking, most of the locks installed on doors are trumpet locks. Because they are more convenient to use and install, they are currently installed and used in general places such as homes or offices. Regarding the locking method of trumpet locks, one of them is to set a drive shaft at the center of the door handle on the inner side of the door, and rotate the drive shaft through a knob to lock the trumpet lock. The door handle on the outer side of the door is equipped with a lock body, so that the locked state can only be released by using a key. Its configuration is generally as disclosed in U.S. Patent Publication No. 6,598,440. Since the drive shaft set at the inner door handle end is pre-assembled to a cylindrical sleeve, and the whole can rotate freely in the inner door handle without relevant positioning mechanisms, when assembling the inner and outer door handles, the inner door handle needs to rotate the drive shaft and the cylindrical sleeve respectively so that the cylindrical sleeve can be aligned with the lock column set at the outer end before assembling. However, the alignment method is extremely difficult. In addition, as shown in it, the cylindrical sleeve only has a single-direction combination method, so it is necessary to continuously align and try during assembly, resulting in extremely time-consuming installation. Figure 7 As shown, the cylindrical sleeve only has a single-direction combination method, so it is necessary to continuously align and try during assembly, resulting in extremely time-consuming installation.

[0004] Another drawback of existing trumpet locks is that since the thickness of most doors is about between 32 mm and 60 mm, when the thickness of the door body is relatively thin, the elastic element sleeved on the rotary shaft will be greatly compressed, resulting in an increase in the resistance of the rotary shaft to rotate. When operating later, a greater torque needs to be applied to rotate the rotary shaft, which will reduce the operability during locking and unlocking. Summary of the Invention

[0026] 1. Through the settings of the transmission shaft, the inner lining and the rotating shaft, the present invention can be pre-limited in the rotating direction and assembled and positioned, enabling the operator to quickly pre-assemble the lock body. When the user installs it by himself after purchase, the lock rod and the transmission column configured on the second turning handle at the other end of the lock can be directly connected to the inner lining and the rotating shaft, and there is no need to rotate the inner lining and the rotating shaft to align them with the lock rod and the transmission column at all, which can improve the convenience and efficiency of the operator and the user during assembly; in addition, through the connection between the inner lining and the rotating shaft, by the settings of the limiting member and the positioning portion, when they are configured as a plurality of corresponding planes, the connection is not limited to a single direction. Therefore, when the operator performs the connection between them, only a little rotation is needed to enable the transmission shaft, the inner lining and the rotating shaft to be connected to each other and positioned in the rotating direction, making it easier to carry out their assembly.

[0027] 2. Through the setting of the braking block, the present invention can be modularized and save its materials, reducing the manufacturing cost of the inner lining. With the setting of the buckling portion of the braking block, the braking block can also be directly connected to the connecting portion of the rotating shaft; preferably, with the settings of the sliding member and the sliding unit, when the braking block moves toward the elastic element in the connecting portion, the braking block expands outward in the radial direction of the rotating shaft, which can disperse the elastic force of the elastic element in the axial direction to a certain extent. When installed on a thinner door body, the elastic force can be reduced, improving the smoothness when rotating the rotating shaft. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0056] Regarding the technical means adopted by the present invention, several preferred embodiments are cited below in conjunction with the drawings for detailed description, so as to deeply understand and recognize the present invention.

[0057] Please first refer to Figures 1 to 5 as shown, which is the first embodiment of the present invention. The present invention is a rotary locking and positioning structure of a lock, which includes:

[0058] A transmission shaft 1, which is arranged in a cylindrical shape and is used for drivingly connecting to a first turning handle 21 configured in a lock 2; at least one limiting component 11 is arranged on the inner edge of the transmission shaft 1;

[0059] An inner lining 3, which is sleeved inside the transmission shaft 1, and the inner lining 3 is provided with a positioning portion 31 corresponding to the limiting component 11 for limiting the movement of the inner lining 3 in the rotational direction inside the transmission shaft 1 and enabling the inner lining 3 to axially move inside the transmission shaft 1; at least one limiting unit 32 is axially arranged on the inner edge of the inner lining 3; and

[0060] A rotating shaft 4, one end of which is provided with a connecting portion 41; the connecting portion 41 is provided with a positioning unit 411 corresponding to the limiting unit 32 for limiting the movement of the rotating shaft 4 in the rotational direction inside the inner lining 3 and enabling the rotating shaft 4 to axially move correspondingly inside the inner edge of the inner lining 3.

[0061] With the foregoing arrangement, the drive shaft 1 can be provided with a limiting member 11, whereby the inner liner 3 can be assembled within the drive shaft 1, and the movement of the inner liner 3 in the rotational direction within the drive shaft 1 can be restricted, while the inner liner 3 can still move axially within the drive shaft 1; and through the positioning unit 411 of the limiting unit 32 and the connecting portion 41, the rotating shaft 4 can also be restricted in the rotational direction and can be axially movably connected to the inner edge of the inner liner 3; thus, it can be understood that the main purpose and effect of the present invention is that when the lock 2 is assembled from a disassembled state, as Figure 4 shown, the drive shaft 1, the inner liner 3 and the rotating shaft 4 can be pre-assembled to form a single component, so as to facilitate corresponding connection to the lock 2, and during the foregoing assembly process, they can be easily aligned and connected, and are not easily detached, so as to improve the convenience and efficiency during the assembly process, and can enhance the convenience when subsequently installed on a door body 5.

[0062] In a specific embodiment, the lock 2 can be a horn lock or a handle lock or other locks 2 with a turning handle. This embodiment takes the horn lock as an example for illustration, but is not limited thereto.

[0063] Therefore, as Figure 2 shown, the lock 2 mainly includes a first component A, a second component B and a locking device 6. Among them, the first component A is one end of the lock 2 configured with the first turning handle 21, which is mainly used to be configured on the inner side of the door body 5 for the user to lock by rotating a knob that drives the rotating shaft 4; the setting of the drive shaft 1 is mainly for the first turning handle 21 to be driven and connected, and then to open the locking device 6; and the purpose of setting the inner liner 3 is that it can be pushed by the transmission column 24 or the lock rod 25 configured by the second component B to adapt to the thickness of the installed door body 5. At the same time, after the inner liner 3 is pushed, as Figure 5 shown, by pushing the inner liner 3 by the transmission column 24 or the lock rod 25, the positioning unit 411 of the rotating shaft 4 is disengaged from the limiting unit 32 of the inner liner 3, so as to release the limit of the rotating shaft 4 in the rotational direction. The purpose is that when installed on the door body 5, the rotation of the rotating shaft 4 does not drive each other with the drive shaft 1; the setting of the rotating shaft 4 is mainly used to connect to the lock rod 25 configured by the second component B. By rotating the knob on the rotating shaft 4, the rotating shaft 4 is rotated and drives the lock rod 25 and the transmission column 24 to rotate synchronously, so that the transmission column 24 drives the locking device 6 to lock, so as to achieve its anti-theft effect; it should be particularly noted that the second component B and the locking device 6 can be the configurations of existing locks 2, and in other embodiments, they can also be the configurations of the locks 2 claimed in the present invention, and their setting methods will be described in detail later.

[0064] First, regarding the connection method of the transmission shaft 1 and the inner lining 3, in one embodiment, the limiting component 11 is formed by concave molding within the transmission shaft 1. Thus, it can be understood that the limiting component 11 can be formed by stamping, indentation, or direct molding, etc., so that a convex block is formed within the transmission shaft 1 for the limiting component 11, and the positioning portion 31 of the inner lining 3 is a correspondingly concave groove, achieving the aforementioned effect of limiting the inner lining 3 in the rotational direction and enabling the inner lining 3 to axially move. In a preferred embodiment, two such limiting components 11 can be provided on the transmission shaft 1, and the limiting components 11 are symmetrically arranged, whereby the inner lining 3 can be correspondingly assembled within the transmission shaft 1 based on the limiting components 11 in two directions of 0 degrees and 180 degrees.

[0065] The second embodiment of the present invention is as Figures 6 to 9 shown. The limiting component 11 and the positioning portion 31 are arranged as corresponding sliders and chutes. Therefore, as shown in this embodiment, the positioning portion 31 is a slider protruding from the inner lining 3, and the limiting component 11 is configured as a concave or through chute, which can also achieve the same effect as described above. It can be understood that since the positioning portion 31 is formed by protruding from the inner lining 3, the positioning portion 31 has elasticity in the radial direction, thereby facilitating the process of inserting the inner lining 3 into the transmission shaft 1. The positioning portion 31 can be elastically compressed and elastically reset when it is aligned with the limiting component 11 to achieve its assembly. However, the above-described configuration methods of the limiting component 11 and the positioning portion 31 are only illustrative examples and are not limited thereto. The configuration of this embodiment is as described above, and Figure 8 、 Figure 9 shown. The inner lining 3 is pushed by the transmission column 24 to disengage the positioning unit 411 of the rotating shaft 4 from the limiting unit 32 of the inner lining 3, so as to release the limitation of the rotating shaft 4 in the rotational direction.

[0066] In other embodiments, as Figures 10 to 23 shown, the limiting component 11 and the positioning portion 31 are corresponding planes. Thus, it can be understood that the transmission shaft 1 can form the limiting component 11 by stamping, indentation, or direct molding, etc., and the inner lining 3 can directly or by cutting form the positioning portion 31 corresponding to the plane, which can also achieve the same effect as described above, that is, limiting the inner lining 3 in the rotational direction and enabling axial movement.

[0067] Regarding the arrangement between the inner liner 3 and the rotating shaft 4 in the first and second embodiments, the arrangement for limiting and axial displacement is the same as the connection method between the transmission shaft 1 and the inner liner 3. The limiting unit 32 and the positioning unit 411 are corresponding planes, and the limiting unit 32 and the positioning unit 411 are arranged by being connected through planes. When the second component B is not assembled, the rotating shaft 4 can be limited in the rotating direction, and when the second component B is assembled, the inner liner 3 can axially move; in addition, in one embodiment, two limiting units 32 can be provided on the inner liner 3, and the limiting units 32 are symmetrically arranged, so that the rotating shaft 4 can be correspondingly connected to the inner edge of the inner liner 3 in two directions of 0 degrees and 180 degrees with the limiting unit 32 as the reference.

[0068] Regarding the arrangement of the inner liner 3 itself, it can be as shown in the first and second embodiments of the present case, which is an integral setting. In the third embodiment as shown in Figures 10 to 13 , Figures 14 to 17 the fourth embodiment and Figures 18 to 23 the fifth embodiment shown in

[0069] Figures 10 to 13 it can also be configured to include two corresponding braking blocks 33. The braking blocks 33 are correspondingly sleeved outside the connecting portion 41 in the radial direction of the connecting portion 41, and can be connected to the transmission shaft 1 as described in the foregoing embodiments. Figures 14 to 17 The difference between the third embodiment shown in

[0070] and the fourth embodiment shown in

[0071] is that the lengths of the braking blocks 33 are different, which exemplarily shows that they can have different forms of configurations and arrangement methods, and can be adapted to door bodies 5 of various thicknesses.

[0070] In order to facilitate the inner liner 3 to be configured as the braking blocks 33, it can be firmly slid and fixed on the rotating shaft 4 and is not easy to fall off, and the convenience during assembly is improved. Therefore, preferably, for the braking blocks 33 as described in the third and fourth embodiments, the limiting unit 32 is configured as a buckling portion 331 respectively provided at the inner edges of both ends of the braking block 33 in the circumferential direction, and the positioning unit 411 is a buckling rail 412 provided at the outer edge of the connecting portion 41 corresponding to the buckling portion 331 and arranged along the axial direction of the connecting portion 41, so that the braking block 33 can be buckled to the buckling rail 412 of the connecting portion 41 through the buckling portion 331, so that it can be positioned in the radial direction and can axially slide on the buckling rail 412.

[0071] Regarding the arrangement of the inner lining 3 in the third to fifth embodiments, its end can be directly pushed by the transmission column 24 or the locking rod 25 configured by the second component B, causing the positioning portion 31 of the inner lining 3 to disengage from the limiting member 11 of the transmission shaft 1. When installed on the door body 5, the limit in the rotational direction between them is released; in other embodiments, the braking block 33 further protrudes a pushing block 332 on its inner edge, and a connecting hole 413 is axially provided at the end of the connecting portion 41. A through groove 415 corresponding to the pushing block 332 is provided on the side edge of the connecting portion 41, and the through groove 415 communicates with the connecting hole 413, so that the pushing block 332 can pass through the through groove 415 and extend into the connecting hole 413. When the locking rod 25 configured by the second component B is connected to the connecting hole 413, the pushing block 332 can be simultaneously pushed to achieve the aforementioned purpose.

[0072] Since the thicknesses of the door bodies 5 are different, in order to ensure that the first component A and the second component B can be properly assembled and configured on the installed door body 5, and to enable the inner lining 3 or the rotating shaft 4 to achieve the aforementioned easy installation, and when installed on the door body 5, it can be pushed to make the positioning portion 31 disengage from the limiting member 11, or in the first and second embodiments, the positioning unit 411 disengage from the limiting unit 32. Therefore, in one embodiment, an elastic element 7 is further provided at one end of the inner lining 3 relative to the transmission shaft 1, and the elastic element 7 applies an elastic force to the inner lining 3 in the direction of the transmission shaft 1.

[0073] As in the first embodiment, the inner lining 3 radially protrudes a convex portion 34 outward at one end. One end of the elastic element 7 abuts against the convex portion 34, and the other end can directly abut against the inner wall surface of the first rotating handle 21; as shown in the second embodiment, a resisting portion 12 protrudes from the transmission shaft 1, and both ends of the elastic element 7 elastically abut against the convex portion 34 and the resisting portion 12 respectively; in other embodiments, as shown in the third to fifth embodiments of the present invention, the convex portion 34 may not be provided on the inner lining 3, and directly on the axial periphery of the inner lining 3 or the axial periphery of the braking block 33, by means of adhesion, welding, assembly, etc., and a receiving portion 42 is radially protruded at one end of the rotating shaft 4 relative to the connecting portion 41, and the elastic element 7 is provided between the receiving portion 42 and the axial periphery of the braking block 33; the foregoing is only an example and is not limited thereto.

[0074] When the elastic element 7 is configured, when the door body 5 is relatively thin, the drive column 24 or the lock rod 25 configured in the second component B will push the inner lining 3 more deeply, which will cause the elastic element 7 to be more compressed, resulting in an increase in the elastic force generated by it. When one end of the elastic element 7 abuts against the inner wall surface of the first rotary handle 21, it will not affect the resistance of the rotary shaft 4 in the rotation direction. However, when one end of the elastic element 7 is abutted against the receiving portion 42 of the rotary shaft 4 as shown in the third to fifth embodiments, it will generate a greater resistance to the rotary shaft 4 in the rotation direction, making it difficult for the rotary shaft 4 to rotate or causing a situation where the rotation is not smooth. Therefore, as Figures 18 to 23 shown in the fifth embodiment, the limiting unit 32 is configured with at least one sliding member 333 provided on the braking block 33, and the positioning unit 411 is configured with a sliding unit 414 corresponding to the joint portion 41 and connected to the sliding member 333. And the sliding member 333 and the sliding unit 414 are used when the braking block 33 moves toward the elastic element 7 at the joint portion 41, as Figure 21 , Figure 23 shown, will cause the braking block 33 to expand outward in the radial direction of the rotary shaft 4, so that the elastic force of the elastic element 7 in the axial direction can be dispersed to a certain extent, so as to improve the smoothness of the rotary shaft 4 when it is forced to rotate when the thickness of the door body 5 is relatively thin; and in this embodiment, the braking block 33 can be a plastic product formed by injection molding. If it is necessary to change to a metal material considering the strength requirements of the component, in one embodiment, the braking block 33 can be configured as Figure 20 shown in the form, which is formed by a metal stamping process, and it also has the configuration of the sliding member 333, and its push block 332 can be configured as in the third embodiment, and it is only for illustration and not limited thereto.

[0075] Regarding the specific configuration of the sliding member 333 and the sliding unit 414, in one embodiment, the sliding member 333 and the sliding unit 414 are corresponding tracks and convex walls. The present invention is illustrated by taking the sliding member 333 as a track and the sliding unit 414 as a convex wall, but is not limited thereto; wherein, the track includes a straight groove 3331 and an inclined groove 3332, the straight groove 3331 corresponds to the axial direction of the assembly portion 41, and the inclined groove 3332 is inclined outwardly in the radial direction of the assembly portion 41, in order to achieve the purpose of the aforementioned detent block 33 moving toward the direction of the elastic element 7 at the assembly portion 41 to expand outward, so it can be known that the angle between the straight groove 3331 and the inclined groove 3332 is It can be an obtuse angle, so that when the elastic element 7 is pressed, the detent block 33 can be expanded outward, and when the elastic element 7 is elastically reset, the detent block 33 will be reset by the elastic force of the elastic reset to make the convex wall located in the straight groove 3331, so that the detent block 33 is in a non-expanded state; and in order to facilitate the detent block 33 to be easily expanded outward when subjected to force, the push block 332 can be provided with an inclined surface 3321 at one end in the direction of the straight groove 3331, and the through groove 415 can also be a corresponding inclined sliding surface at the position corresponding to the inclined surface 3321, so that the detent block 33 can be expanded outward by the inclined sliding of the inclined surface 3321 and the sliding surface. By this arrangement, when the thickness of the door body 5 is small, the large compression of the elastic element 7 can be avoided, which causes a large resistance to the rotating shaft 4. Therefore, if Figure 21 , Figure 22 As shown, when the locking rod 25 pushes the detent block 33 to move, the detent block 33 will expand outwards, and after the detent block 33 moves a certain distance, a channel P is formed due to the outward expansion of the detent block 33, so that the locking rod 25 can no longer push the detent block 33 and passes through the channel P. If the elastic element 7 is not over-compressed, the problem of excessive resistance to the rotating shaft 4 and difficulty in rotation can be effectively avoided.

[0076] As mentioned above, the present invention can be configured in the existing lock 2 to achieve the effect of easy assembly. In one embodiment, the present invention is described by taking the first embodiment as an example, and it can be known that the same can be applied to other embodiments accordingly. Figures 1 to 4 and Figure 24 , Figure 25 As shown, the configuration when it is specifically applied to the lock 2 is that the first component A of the lock 2 includes:

[0077] A first turning handle 21, which is pivotally connected to a first positioning cover 211, and the first turning handle 21 is drivingly connected to the transmission shaft 1, the transmission shaft 1 is cylindrical, and the inner edge of the transmission shaft 1 is provided with the limiting component 11;

[0078] The liner 3 is sleeved inside the transmission shaft 1, and the liner 3 is provided with a positioning portion 31 corresponding to the limiting component 11, so as to limit the movement of the liner 3 in the rotation direction of the transmission shaft 1 and enable the liner 3 to move axially on the transmission shaft 1; the limiting unit 32 is axially arranged on the inner edge of the liner 3; and

[0079] The rotating shaft 4 has a connecting portion 41 at one end; the connecting portion 41 is provided with a positioning unit 411 corresponding to the limiting unit 32, which is used to limit the movement of the rotating shaft 4 in the rotation direction within the lining 3, and can correspond to the axial movement to the inner edge of the lining 3, and an elastic element 7 with axial elastic direction is provided between the rotating shaft 4 and the lining 3.

[0080] According to the foregoing, it is obvious that the configuration of the present invention allows the transmission shaft 1, the lining 3 and the rotating shaft 4 to be pre-assembled into a single component, so as to facilitate the corresponding connection to the first component A of the lock 2, and the matching process can be easily aligned and assembled and not easy to fall off, so as to improve the convenience and efficiency of the assembly process.

[0081] The configuration of the second component B of the lock 2 is as follows Figure 24 , Figure 25 As shown, it includes a second handle 23, which is arranged at one end of the lock 2 opposite to the first handle 21. The second handle 23 is provided with a transmission column 24 and a locking rod 25. When one of the transmission column 24 and the locking rod 25 is in a group connection state, it can correspondingly abut against the end of the lining 3, and the locking rod 25 is correspondingly transmission-connected to the end of the rotating shaft 4.

[0082] It is known that after the present invention is manufactured, Figure 2 As shown, the lock 2 can be pre-assembled to form three major components of the first component A, the second component B and the locking device 6. When the user needs to install it on the door body 5, he only needs to make the transmission column 24 and the locking rod 25 pass through the locking device 6, and then the locking rod 25 can be directly driven and assembled to the end of the rotating shaft 4. Since the rotating shaft 4 has been limited in the rotation direction, the whole will not rotate during the process. Therefore, it is only necessary to slightly rotate the first component A so that the locking rod 25 can be correspondingly assembled to the rotating shaft 4 to complete the matching. There is no need to rotate the rotating shaft 4 and calibrate the alignment to assemble it to the locking rod 25 as in the prior art. Therefore, the present invention is indeed convenient during assembly and can improve assembly efficiency.

[0083] In terms of its specific configuration, the lock 2 of the present invention has the second turning handle 23 pivotally connected to a second positioning cover 231 and drivingly connected to a bushing 232. A transmission unit 233 is drivingly arranged on the bushing 232. The transmission unit 233 is provided with a transmission post 24. The transmission post 24 is sleeved on the outer edge of the lock rod 25. A transmission assembly 22 is drivingly arranged on the transmission shaft 1. The transmission assembly 22 is correspondingly drivingly connected to the transmission post 24. The second turning handle 23 is provided with a lock body 26. The lock body 26 is drivingly connected to the lock rod 25. A lock disc 27 is arranged inside the second positioning cover 231. The lock disc 27 is provided with at least one lock groove 271. A locking element 251 protrudes radially from the lock rod 25. A lock piece 28 is sleeved on the lock rod 25 and correspondingly arranged on the bushing 232. At least one locking unit 281 corresponding to the lock groove 271 and protruding from the bushing 232 protrudes radially from the lock piece 28. The lock piece 28 is provided with a first recess 282 and a second recess 283 corresponding to the locking element 251. An abutting member 234 is arranged inside the bushing 232. An elastic member 235 is arranged between the abutting member 234 and the lock piece 28.

[0084] Thus, the first turning handle 21 can drive the transmission post 24 to rotate through the transmission shaft 1 and the transmission assembly 22, and then drive the locking device 6, so that the lock bolt 61 configured in the locking device 6 can be retracted to an open state. The transmission configuration of the locking device 6 and the lock bolt 61 belongs to the prior art and will not be elaborated here. The second turning handle 23 can also drive the transmission unit 233 through the bushing 232, and thereby rotate the transmission post 24 to make the locking device 6 in the aforementioned open state.

[0085] The locking of the locking device 6 is mainly carried out by driving the lock rod 25. The lock rod 25 can be driven by the lock body 26 or pivoted through the rotating shaft 4. When in a locked state, as Figure 25 、 Figure 26 shown, the lock rod 25 is driven to rotate so that the locking element 251 is located at the position of the second recess 283. It should be particularly noted that the depth of the second recess 283 is shallower than that of the first recess 282, so that the lock piece 28 axially elastically compresses the elastic member 235, and the locking unit 281 correspondingly locks to the lock groove 271. Thus, since the bushing 232 is synchronously driven with the lock piece 28, when the locking unit 281 locks to the lock groove 271, the bushing 232 will be limited. Therefore, at this time, the second turning handle 23 cannot be rotated by driving the bushing 232, achieving the anti-theft effect.

[0086] When in an unlocking position, as Figure 27As shown, the lock rod 25 is driven to rotate so that the locking element 251 is correspondingly located at the position of the first recess 282. Since the first recess 282 is relatively deep and the axial position of the lock rod 25 is always fixed, the elastic member 235 elastically returns and axially abuts against the lock piece 28, so that the first recess 282 of the lock piece 28 abuts against the locking element 251, which will cause the locking unit 281 to be disengaged from the lock groove 271. Therefore, at this time, the first turning handle 21 and the second turning handle 23 can be rotated as described above to unlock the locking device 6.

[0087] Continuing as described above, since the elastic member 235 elastically abuts against the lock piece 28, in order to make it easy for the lock rod 25 to drive the locking element 251 to move and smoothly disengage from the first recess 282 or the second recess 283, arc-shaped guide surfaces can be provided on the first recess 282 and the second recess 283 in the rotation direction corresponding to the locking element 251, so as to facilitate the lock rod 25 to axially push the lock piece 28 when it is forced to rotate.

[0088] The above description is illustrative rather than restrictive to the present invention. Those of ordinary skill in the art understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the claims, and all of them will fall within the protection scope of the present invention.
