[0031] The rotatable, liftable and swingable bicycle dress line clamping tool proposed in this application will be further described below in conjunction with specific implementation methods and drawings.

[0032] See also Figure 1 , Figure 2The invention discloses a bicycle dress line clamping tool which can rotate, lift and deflect, and comprises a telescopically adjustable column 1, a rotating seat 2 installed on the column 1 and rotatable in a horizontal plane relative to the column 1, a rotating arm 3 installed on the rotating seat 2 and rotatable in a vertical plane relative to the rotating seat 2, and a deflectable clamp installed on the rotating arm 3. The deflectable clamp comprises a clamping unit 4 and a deflection control mechanism 9. The deflection control mechanism 9 is used to control the swing angle of the clamping unit 4 and enable the clamping unit 4 to switch and fix between a first fixed position and a second fixed position. The starting point and the end point of the swing of the clamping unit 4 correspond to the first fixed position and the second fixed position respectively.

[0033] Of course, the column 1 is equipped with a telescopic control mechanism 5 to adjust the length of the column 1. Figure 3 The column 1 includes an outer tube 11 and an inner tube 12 which are coaxially arranged. The upper end of the inner tube 12 is placed inside the outer tube 11, and the lower end of the inner tube 12 is located outside the outer tube 11. The telescopic control mechanism 5 controls the telescopic movement of the column 1 by controlling the inner tube 12 to move up and down relative to the outer tube 11. The upper end of the outer tube 11 is connected to the top connector 13, and the lower end of the inner tube 12 is connected to the rotating seat 2.

[0034] In some embodiments of the present invention, the telescopic control mechanism 5 includes a first transmission mechanism and a first drive mechanism. Optionally, the first transmission mechanism is used to convert the rotational motion of the first drive mechanism into the linear motion of the inner tube 12. Figure 3 In the exemplary embodiment, the first transmission mechanism includes a transmission screw 51, a transmission nut 52 and a bevel gear vertical transmission mechanism, the first driving mechanism includes a hand wheel 54, the transmission screw 51 is coaxially placed in the inner tube 12, the transmission screw 51 cannot move up and down, the transmission nut 52 is threadedly matched with the transmission screw 51 and connected to the inner tube 12, one of the bevel gears of the bevel gear vertical transmission mechanism is installed on the transmission screw 51, and the other bevel gear of the bevel gear vertical transmission mechanism is connected to the hand wheel 54. The hand wheel 54 is rotated, and the rotation of the hand wheel 54 is transmitted to the transmission screw 51 through the bevel gear vertical transmission mechanism, and the rotation of the transmission screw 51 drives the transmission nut 52 to move up and down along the transmission screw 51, and then drives the inner tube 12 to move up and down.

[0035] Among them, the handwheel 54 is rotatably connected to the outer tube 11, and there is a bearing between the rotating shaft of the handwheel 54 and the outer tube 11; there is a first avoidance opening 121 on the wall of the inner tube 12, and the first avoidance opening 121 is used to avoid the bevel gear vertical transmission mechanism, etc., to prevent the bevel gear vertical transmission mechanism from blocking the up and down movement of the inner tube 12.

[0036] Optionally, a lower support member 55 is mounted on the outer tube 11, and a bevel gear connected to the transmission screw 51 is mounted on the lower support member 55 with a bearing disposed therebetween. The upper end of the transmission screw 51 is rotatably connected to the top connector 13 via a bearing.

[0037] It is described above that the first driving mechanism includes the hand wheel 54, but the present invention is not limited thereto. In other embodiments, the first driving mechanism includes a motor, and the motor is driven automatically.

[0038] It is described above that the telescopic control mechanism 5 includes a transmission screw 51, a transmission nut 52, a bevel gear vertical transmission mechanism and a hand wheel 54. However, the present invention is not limited thereto. For example, in some embodiments, the telescopic control mechanism 5 does not include a bevel gear vertical transmission mechanism, and the hand wheel 54 or the motor is directly connected to the transmission screw 51. For another example, in some embodiments, the telescopic control mechanism 5 includes a fastening bolt installed on the outer tube 11, and the length control is achieved by tightening the fastening bolt so that its inner end is pressed against the inner tube 12 or by screwing the inner end of the fastening bolt into a matching hole on the inner tube 12. This is a conventional technology in the art and will not be described in detail here.

[0039] The rotating seat 2 is provided with a horizontal rotation locking mechanism 6, which locks the rotating seat 2 to prevent it from rotating in the horizontal plane relative to the column 1. Figure 3 , Figure 4 In the exemplary embodiment, the horizontal rotation locking mechanism 6 includes a gear sleeve 61, a locking block 62 and a first operating mechanism. The locking block 62 has teeth for meshing with the gear sleeve 61. The axis of the gear sleeve 61 is parallel to the vertical plane. The gear sleeve 61 is fixedly connected to the column 1. The locking block 62 is installed on the rotating seat 2 and can move linearly relative to the gear sleeve 61. The locking block 62 has a locking position and an unlocking position. When the locking block 62 is in the locking position, the locking block 62 is meshed with the gear sleeve 61; when the locking block 62 is in the unlocking position, the locking block 62 is separated from the gear sleeve 61. The first operating mechanism is used to drive the locking block 62 to move linearly relative to the gear sleeve 61, thereby switching the gear sleeve 61 between the locking position and the unlocking position.

[0040] In some embodiments of the present invention, the upper end of the gear sleeve 61 is fixed to the connecting tube 66 by screws, and the connecting tube 66 is fixedly connected to the lower end of the column 1 .

[0041] It is worth noting that there are many mechanisms for driving the locking block 62 to achieve linear motion, such as gear racks, screw nuts, cam mechanisms, etc. Those skilled in the art can reasonably set them according to needs. In an exemplary embodiment, Figure 4As shown, the first operating mechanism includes an adjusting screw 63 and a rotating handle 64. The rotating seat 2 has a central circular hole matching the gear sleeve 61. The rotating seat 2 is sleeved outside the gear sleeve 61 and is rotatably connected to the gear sleeve 61. The locking block 62 is placed in the linear groove 20 of the rotating seat 2. Under the constraint of the linear groove 20, the locking block 62 can only move radially relative to the rotating seat 2. The rotating seat 2 has a threaded hole matching the adjusting screw 63. The adjusting screw 63 is installed in the threaded hole. One end of the adjusting screw 63 is rotatably connected to the locking block 62, and the other end of the adjusting screw 63 is connected to the rotating handle 64. Rotating the handle 64 clockwise or counterclockwise can drive the adjusting screw 63 to rotate and move radially inward or outward simultaneously, and then drive the locking block 62 to move radially inward or outward, so that the locking block 62 is engaged or separated from the gear sleeve 61. When the locking block 62 is engaged with the gear sleeve 61, the locking block 62 and the rotating seat 2 cannot rotate in the horizontal plane relative to the gear sleeve 61 and the column 1, thereby achieving locking; and when the locking block 62 is separated from the gear sleeve 61, the locking block 62 and the rotating seat 2 can rotate freely in the horizontal plane relative to the gear sleeve 61 and the column 1, thereby achieving unlocking.

[0042] See also Figure 3 , Figure 4 In the exemplary embodiment, the rotating seat 2 includes a base 21, a pressure cover 22 and a vertical rotating shaft 23. The upper part of the vertical rotating shaft 23 is coaxially placed in the gear sleeve 61 and rotates with the gear sleeve 61 through a bearing. The base 21 is fixedly connected to the flange at the lower end of the vertical rotating shaft 23 by screws; the pressure cover 22 is located above the base 21 and is fixedly connected to the base 21. The linear groove 20 is located on the pressure cover 22, and the adjusting screw 63 is installed in the threaded hole of the pressure cover 22. A support ring 65 is coaxially installed outside the gear sleeve 61. The support ring 65 is screwed, welded or integrally manufactured with the gear sleeve 61. There is an annular inner step on the inner wall of the pressure cover 22 that is adapted to the support ring 65. The annular inner step is supported on the support ring 65, so that the weight of the rotating seat 2 is transferred to the gear sleeve 61, and then transferred to the column 1.

[0043] The rotating arm 3 is provided with a vertical rotation locking mechanism 7, through which the rotation angle of the rotating arm 3 in the vertical plane can be controlled. Figure 1 , Figures 5 to 9In the exemplary embodiment, the vertical rotation locking mechanism 7 includes a brake disc 71 and a locking pin assembly. The brake disc 71 is fixedly connected to the base 21 of the rotating seat 2. The rotating arm 3 is rotatably connected to the rotating core shaft 30 and a bearing is provided therebetween. The rotating core shaft 30 is installed in the center hole of the brake disc 71 and the two are fixed together by bolts or screws. The locking pin assembly is installed on the brake disc 71, and the locking pin assembly includes a locking pin 72, a locking pin seat 74 and a first handle 74. The locking pin seat 74 and the brake disc 71 are both provided with pin holes matching the locking pin 72. The locking pin 72 is installed in the pin holes of the brake disc 71 and the locking pin seat 74 and can rotate relative to the brake disc 71 and move in a first direction, and the first direction is parallel to the axial direction of the rotating spindle 30; a plurality of locking holes 31 are arranged on the same circumference around the rotating spindle 30 on the rotating arm 3, and the rotating arm 3 performs a rotational motion, and the plurality of locking holes 31 can be opposite to the locking pin 72 one by one, and the locking pin 72 has a locking position and an unlocking position; when the locking pin 72 is in the locking position, the locking pin 72 is inserted into one of the locking holes 31 of the rotating arm 3; when the locking pin 72 is in the unlocking position, the locking pin 72 is separated from the rotating arm 3. The first handle 74 is connected to the locking pin 72 and is used to drive the locking pin 72 to move in a first direction relative to the brake disc 71, thereby switching the locking pin 72 between a locked position and an unlocked position.

[0044] When the lock pin 72 is in the locked position, it is switched to the unlocked position to prevent the lock pin 72 from moving in an unexpected situation. Figure 6 , Fig. 9 In an exemplary embodiment, a bar hole 75 matching the first handle 74 is provided on the lock pin seat 74, and one end of the first handle 74 extends into the lock pin seat 74 from the bar hole 75 to connect with the lock pin 72. The bar hole 75 allows the first handle 74 to move in a first direction relative to the lock pin seat 74 and can limit the linear displacement of the lock pin 72; a bayonet 76 is provided at one end of the bar hole 75. When the lock pin 72 is driven to move to the locking position by the first handle 74, the first handle 74 is exactly located at the bayonet 76. At this time, the first handle 74 is rotated with the lock pin 72 as the rotation center to clip the handle rod into the bayonet 76. Due to the restriction of the bayonet 76 on the first handle 74, the lock pin 72 can be prevented from withdrawing from the lock hole 31 of the rotating arm 3, thereby keeping the rotating arm 3 in a locked state.

[0045] It is worth noting that the lock pin seat 74 and the brake disc 71 can be manufactured integrally or separately.

[0046] When the lock pin 72 is switched to the unlocked position to facilitate adjustment of the angle of the rotating arm 3, the rotating arm 3 is prevented from rotating automatically under the action of its own weight and the gravity of the bicycle, thereby increasing the stability of the angle adjustment. Figure 8 , Fig. 9In some embodiments of the present invention, a damping device 8 is further installed on the brake disc 71. There is an installation cavity on the brake disc 71 for installing the damping device 8. The damping device 8 includes a round spring pin 81. A plurality of indexing grooves 32 matching the round spring pin 81 are arranged on the same circumference around the rotating core shaft 30 on the rotating arm 3. The free end of the round spring pin 81 can be inserted into one of the indexing grooves 32 under the action of the spring, thereby preventing the rotating arm 3 from rotating in the vertical plane; but when the external rotational force increases to a certain extent, the round spring pin 81 can be forced to retract, thereby rotating the rotating arm 3 in the vertical plane. Preferably, the round spring pin 81 is provided with an elastic force adjustment nut 83. The round spring pin 81 and the corresponding elastic force adjustment nut 83 are installed in the same installation cavity. The round spring pin 81 includes a ball pin and a spring. The elastic force adjustment nut 83 is threadedly matched with the brake disc 71, and the ball pin is gap-matched with the installation cavity. The two ends of the spring act on the ball and the elastic force adjustment nut 83 respectively. Under the action of the spring, the free end of the ball pin protrudes from the brake disc 71. The elastic force adjustment nut 83 can limit the round spring pin 81 on the one hand, and adjust the elastic force of the round spring pin 81 on the other hand.

[0047] It is worth noting that the number of indexing grooves 32 can be set reasonably. Of course, the edge of the indexing groove 32 is smoothly transitioned so that the free end of the round spring pin 81 slides in or out of the indexing groove 32.

[0048] In some embodiments, the number of indexing grooves 32 is equal to the number of locking holes 31 and corresponds one to one. When the round-headed spring pin 81 is inserted into a certain indexing groove 32, the locking pin 72 is exactly opposite to one of the locking holes 31. When it is necessary to adjust the angle of the rotating arm 3 in the vertical plane, the locking pin 72 is moved backward and away from the rotating arm 3 through the first handle 74, and then a slight rotational force is applied to the rotating arm 3 to drive the rotating arm 3 to rotate. As the rotating arm 3 rotates, the round-headed spring pins 81 will be inserted into the indexing grooves 32 one by one, so the operator will feel a jam during the rotation operation. Therefore, it is possible to judge whether the locking pin 72 is opposite to one of the locking holes 31 at this time by the jamming feeling of the round-headed spring pin 81 and the indexing groove 32; when rotated to the appropriate angle, the locking pin 72 is moved forward by the first handle 74 to be inserted into the corresponding locking hole 31 of the rotating arm 3, so as to fix the angle of the rotating arm 3 in the vertical plane. Figure 7 As shown in the figure, in an exemplary embodiment, a locking hole 31 is formed at the bottom of each indexing groove 32.

[0049] It is worth noting that the number of the damping devices 8 is reasonably set according to needs; preferably, there are at least two damping devices 8. In the exemplary embodiment, there are three damping devices 8.

[0050] See also Fig.10The clamping unit 4 is rotatably connected to the swing frame 10 via the swing shaft 40, and can swing relative to the swing frame 10 with the swing shaft 40 as a fulcrum. The swing frame 10 is connected to the rotating arm 3. The swing shaft 40 is perpendicular to the rotation axis of the rotating arm 3. The yaw control mechanism 9 controls the swing angle of the clamping unit 4 on the swing frame 10 to be α.

[0051] See also Figures 11 to 14 In an exemplary embodiment, the yaw control mechanism 9 includes a fixed block 91, a movable connecting plate 92, a limiting roller 93 and a spring 94, and the fixed block 91 is fixedly connected to the swing frame 10 or manufactured integrally.

[0052] A fixed connecting plate 95 is mounted on the clamping unit 4, one end of the movable connecting plate 92 is rotatably connected to the fixed connecting plate 95 through the shaft A96, and a limiting roller 93 is mounted on the other end of the movable connecting plate 92, and the limiting roller 93 is parallel to the swing shaft 40. One end of the spring 94 acts on the fixed block 91, and the other end of the spring 94 acts on the limiting roller 93. A contact guide surface 911 for contacting the limiting roller 93 is provided at the bottom of the fixed block 91. Under the pulling force of the spring 94, when the clamping unit 4 swings on the swing frame 10, the limiting roller 93 always keeps in contact with the contact guide surface 911 of the fixed block 91.

[0053] The two ends of the contact guide surface 911 respectively have a first limit groove 912 and a second limit groove 913 adapted to the limit roller 93; in the initial state, the limit roller 93 is stuck in the first limit groove 912, and then the clamping unit 4 is swung, and the limit roller 93 can move along the contact guide surface 911. When the limit roller 93 moves to be stuck in the second limit groove 913, the clamping unit 4 cannot continue to increase the swing angle, thereby realizing the control of the swing angle α.

[0054] It is worth noting that the swing angle can be reasonably set according to needs. Preferably, the swing control mechanism 9 controls the clamping unit 4 on the swing frame 10 to swing at an angle of 30°.

[0055] The swing angle can be controlled by changing the positions of the first limiting groove 912 and the second limiting groove 913 .

[0056] In some embodiments, see Fig.13 A hook 941 is rotatably mounted on the limiting roller 93 through a central hole, and a hook 941 is rotatably mounted on the fixing block 91. The two ends of the spring 94 are respectively hooked on the fixing block 91 and the hook 941 of the limiting roller 93. Preferably, a bearing and a bearing shaft 942 are mounted on the fixing block 91 through a circular hole 914, and a hook 941 is mounted on the bearing shaft 942.

[0057] In order to provide a more stable and balanced pulling force to the limiting roller 93 , in an exemplary embodiment, there are two springs 94 , which are respectively located on both sides of the movable connecting plate 92 , and the two springs 94 act on both ends of the limiting roller 93 .

[0058] In some embodiments, a hook 96 is provided on the movable connecting plate 92, and a pull ring 98 adapted to the hook 96 is movably installed on the fixed block 91. One end of the pull ring 98 is used to hook the hook 96, and the other end of the pull ring 98 is rotatably connected to one end of the second handle 99 through the shaft B981. The second handle 99 is rotatably connected to the fixed block 91 through the shaft C991. By pulling the other end of the second handle 99, the pull ring 98 can be operated to move. Fig.10 At this time, the clamping unit 4 is in the first fixed position and at the starting point of the swing. When the limiting roller 93 of the clamping unit 4 is stuck in the first limiting groove 912, the pull ring 98 is hooked on the hook 96. At this time, the clamping unit 4 is pulled by the pull ring 98 and cannot rotate. When the swing angle of the clamping unit 4 needs to be adjusted, the other end of the second handle 99 is pulled to move the pull ring 98 toward the hook 96, and then the pull ring 98 can be removed from the hook 96 to release the constraint on the clamping unit 4; then the clamping unit 4 can be swung, and when the limiting roller 93 moves to the second limiting groove 913, the clamping unit 4 reaches the end of the swing stroke and is fixed in the second fixed position, please refer to Fig.12 Similarly, see Fig.16 When the limiting roller 93 of the clamping unit 4 is stuck in the second limiting groove 913, the pull ring 98 is hooked on the hook 96. At this time, the clamping unit 4 is pulled by the pull ring 98 and cannot rotate. When the swing angle of the clamping unit 4 needs to be adjusted, the other end of the second handle 99 is pulled to move the pull ring 98 toward the hook 96, and then the pull ring 98 can be removed from the hook 96 to release the constraint on the clamping unit 4; then the clamping unit 4 can be swung in the opposite direction, and when the limiting roller 93 moves to the second limiting groove 913, the clamping unit 4 returns to and is fixed in the first fixed position.

[0059] In some embodiments, the fixed block 91 includes a mounting plate 915 and a swing guide plate 917, the swing guide plate 917 is perpendicular to the mounting plate 915, the mounting plate 915 is fixedly connected to the swing frame 10, the upper edge of the swing guide plate 917 is connected to the mounting plate 915, and the contact guide surface 911, the first limiting groove 912 and the second limiting groove 913 are located at the lower edge of the swing guide plate 917. Preferably, the fixed block 91 is manufactured in one piece.

[0060] The clamping unit 4 can be an internal tensioning clamping tool or an external tensioning clamping tool. In an exemplary embodiment, the clamping unit 4 is an internal tensioning clamping tool. There are many structures of internal tensioning clamping tools, and those skilled in the art can choose according to needs.

[0061] See also Fig.15 In an exemplary embodiment, the clamping unit 4 includes a tensioning body for inserting into and tensioning the middle tube of the bicycle frame, a tensioning trigger mechanism for driving the tensioning body to switch between a tensioned state and a loosened state, and a mounting cylinder 41 for mounting the tensioning body and the tensioning trigger mechanism. There is a swing shaft 40 on both sides of the mounting cylinder 41, and one end of the swing frame 10 has a swing shaft hole 101 adapted to the two swing shafts 40, and the swing shaft 40 is mounted in the swing shaft hole 101. Preferably, the two swing shafts 40 are manufactured integrally with the mounting cylinder 41.

[0062] The tensioning body includes a cone sleeve 42 and at least two tensioning blocks 43. The cone sleeve 42 has an outer cone surface at its lower end, and the inner surface of the tensioning block 43 is an inner cone surface adapted to the outer cone surface of the cone sleeve 42. The tensioning block 43 is arranged on the outer side of the cone sleeve 42 along the circumferential direction and fits with the outer cone surface of the cone sleeve 42. The tension trigger mechanism includes a screw rod 44, an adjusting nut 45 and an operating mechanism 46. The adjusting nut 45 is built into the cone sleeve 42 and is coaxial with the cone sleeve 42. The lower end of the screw rod 44 extends into the cone sleeve 42 and is threadedly matched with the adjusting nut 45. Each tension block 43 is movably connected to the adjusting nut 45 through a clamping block 46. The cone sleeve 42 is provided with a second avoidance opening 421 for the clamping block 46 to pass through. By rotating the screw rod 44, the adjusting nut 45 can be driven to move axially in the cone sleeve 42, driving each tension block 43 to switch between positions close to each other and away from each other.

[0063] The screw rod 44 passes through the inner hole of the mounting tube 41 and is rotatably connected to the mounting tube 41 through a bearing; the upper end of the screw rod 44 is connected to the operating mechanism 46. In an exemplary embodiment, the operating mechanism 46 includes a transmission wheel 51 and a plurality of third handles 462, the third handles 462 are connected to the transmission wheel 51, and the transmission wheel 51 is connected to the screw rod 44.

[0064] The fixed connecting plate 95 is mounted on the cone sleeve 42. Optionally, a fixed sleeve 47 is coaxially mounted on the outer portion of the upper end of the cone sleeve 42, and the fixed sleeve 47 is connected to the fixed connecting plate 95. Preferably, the fixed sleeve 47 and the fixed connecting plate 95 are integrally manufactured; the fixed sleeve 47 is threadedly matched with the cone sleeve 42. In some embodiments, the upper end of the cone sleeve 42 has a flange 422, and the upper end of the fixed sleeve 47 abuts against the flange 422.

[0065] See also Fig.15At this time, each tensioning block 43 is close to each other, and each tensioning block 43 as a whole forms an inner hole in the form of a tapered hole. The diameter of the circumferential surface where the outer surface of each tensioning block 43 is located is smaller than the inner diameter of the clamped part. At this time, the tensioning body is inserted into the middle tube of the frame; then, the transmission wheel 461 is rotated, and the transmission wheel 461 drives the screw rod 44 to rotate, and then drives the adjusting nut 45 and the tensioning block 43 to move upward. At the same time, each tensioning block 43 moves radially due to the action of the outer cone surface of the cone sleeve 42 and then separates. In this way, the tensioning block 43 can be pressed against the wall of the middle tube of the frame to achieve the tensioning and fixing of the frame.

[0066] Since the inner hole formed as a whole by each tensioning block 43 is a tapered hole, and the tapered section of the tapered sleeve 42 is a corresponding tapered hole, when the tensioning block 43 moves under the action of the tensioning trigger mechanism, it can be pushed to move radially outward, thereby tightening and fixing the frame, and the radial force applied by each tensioning block 43 to the middle tube of the frame is uniform, and the clamping stability is good.

[0067] Among them, one of the adjusting nut 45 and the tensioning block 43 has a radial clamping block 46, and the other has a clamping groove 11 adapted to the clamping block 46. One end of the clamping block 46 passes through the second avoidance opening 421 of the cone sleeve 42 and is installed in the clamping groove 11. In some embodiments, the adjusting nut 45 and the clamping block 46 are manufactured integrally.

[0068] In some embodiments, the method of using the present invention is as follows: Figure 2 , Figure 3 In the initial state, the rotating arm 3 does not rotate, and the clamping unit 4 does not swing. At this time, the screw 44 of the clamping unit 4 is parallel to the column, and the swing shaft 40 is parallel to the horizontal plane and perpendicular to the rotation axis of the rotating arm 3 and the rotation axis of the rotating seat 2. First, the column 1 is fixed to other equipment through the top connector 13, and the hand wheel 54 is turned to extend the column 1, and then the clamping unit 4 is lowered, so that the bicycle frame can be clamped with the clamping unit; then the hand wheel 54 is rotated in the opposite direction to retract the column 1 and lift the bicycle frame to a suitable height; then, the operator can turn the rotating handle 64 to unlock the locking block 62, and then rotate the rotating seat 2 to adjust the bicycle frame to any position as required; please refer to Fig.16 By vertically rotating the locking mechanism 7, the bicycle frame can also be rotated to be fixed at any angle in the vertical plane; and the operator can also fix the bicycle frame after swinging it with the swing shaft 40 as a fulcrum to avoid line of sight obstruction and cooperate with the operating position, thereby facilitating the installation of various parts, greatly improving the convenience of operation, and helping to improve assembly efficiency.

[0069] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
