After the two second tool boxes or one first tool box and one second tool box are combined along the second combination direction, the second limiting fixture on the upper tool box can cooperate with the first limiting groove or the second limiting groove on the lower tool box, so that the relative position between the two second tool boxes or one first tool box and one second tool box is limited;

[0022] One end of the second elastic fixing member is an elastic end and the other end is a clamping end, the elastic end contacts the bottom of the second receiving groove, and the relative position of the second elastic fixing member in the second receiving groove is changed by deformation of the elastic end. When the elastic end does not undergo elastic deformation, the clamping end of the second elastic fixing member extends out of the second receiving groove;

[0023] After the two second tool boxes or the first tool box and the second tool box are combined along the second combination direction, the second receiving slot of the upper tool box and the first card slot or the second card slot of the lower tool box form a second receiving cavity, at which time the second elastic fixing member is in the second receiving cavity, and the card connection end of the second elastic fixing member is in the first card slot or the second card slot of the lower tool box; the second limiting assembly cooperates with the second elastic fixing member to realize the connection and fixation between the two second tool boxes or the first tool box and the second tool box;

[0024] The second tool box has two sizes. The length and width of each second tool box are the same, and the height of one second tool box is twice the height of the other second tool box.

[0033] A first wedge block is respectively arranged at both ends of the spring, the inclined surfaces of the first wedge blocks are both away from the spring, a connecting rod is arranged on the side of the first wedge block away from the spring, and a limit block is arranged on the side of the connecting rod away from the first wedge block;

[0034] The middle part of the bottom surface of the pressing part is inwardly concave to form a trapezoidal groove structure;

[0035] In the initial state, the pressing part is not subjected to force, and is pressed outward by the spring, pushing the two first wedge blocks outward, so that the pressing part is pushed upward, and at the same time drives the limit block on the connecting rod to penetrate the sleeve structure and abut against the long side of the pull rod, so that the limit locking member limits the relative position between the pull rod and the sleeve structure;

[0036] When the relative position between the pull rod and the sleeve structure needs to be adjusted, the pressing part is pressed to move along the height direction of the shell toward the limit locking part. The trapezoidal groove structure at the bottom of the pressing part abuts against the inclined surfaces of the two first wedge blocks, and squeezes the two first wedge blocks toward each other, driving the two limit blocks away from the pull rod to release the lock on the pull rod. The pull rod can be dragged to the desired position and the pressing part can be released to lock it again.

[0037] Through the above technical solution, compared with the prior art, the utility model has the following beneficial effects:

At this time, the first elastic fixing member is in the first accommodating cavity, and the clamping end of the elastic fixing member is located in the first clamping groove of the first tool box at the bottom, and a clamping relationship is formed between the clamping end and the first clamping groove, that is, the first limiting assembly cooperates with the elastic fixing member to realize the connection and fixation between the two first tool boxes.

[0040] The operator of the utility model manually lifts the first operating part, so that the elastic fixing piece moves upward, the elastic end is deformed by force, and the clamping end moves at the same time until the clamping end is completely in the first accommodating groove, thereby releasing the clamping relationship between the clamping end of the elastic fixing piece of the upper tool box and the first clamping groove of the lower tool box. At this time, the upper tool box can be moved in the opposite direction of the first combination direction, and the limit between the two tool boxes can be released.

[0041] The first elastic fixing member of the utility model is always in the first receiving groove by extending the first operating portion into the first operating window. When the tool box is used alone, the elastic fixing member cannot fall from the first receiving groove to the external environment.

[0042] 5. The first limit clamp of the utility model can automatically realize the clamping connection between the first elastic fixing member and the first clamping groove while limiting the position. That is, the operator can complete the combination and stacking of the two first tool boxes by pushing the upper first tool box along the first combination direction, which is very convenient to operate.

[0043] When the second limiting clamp and the second limiting slot are limiting, the second elastic fixing member can be automatically connected with the first slot or the second slot. That is, the operator can push the second tool box above along the second combination direction to complete the combination and stacking of two second tool boxes or a first tool box and a second tool box.

That is, there is no limit on the height of the first toolbox and the second toolbox, and toolboxes of any size can be stacked. It can be seen that the present invention has a wide range of applications;

[0045] 7. The pull rod of the pull rod tool box of the utility model can be adjusted arbitrarily, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0070] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0071] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not indicate the importance of the components, and therefore cannot be understood as a limitation on the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the scope of protection of the present invention. Example

[0072] This embodiment provides a preferred implementation scheme, a combined multi-layer pull rod tool box, such as Figures 1 to 22 As shown, the combined multi-layer pull rod tool box includes at least two first tool boxes 1, a first limit assembly and a first elastic fixing member 2 which are sequentially distributed up and down. The specific structure is described as follows:

[0073] The above-mentioned first limiting assembly includes at least one first limiting groove 3 and at least one first limiting clip 6. The first limiting groove 3 is opened on the top surface of the first tool box 1. First ear plates 4 are arranged at any two adjacent corners of the first limiting groove 3. The direction from the side of the first limiting groove 3 away from the two first ear plates 4 to the side close to the first ear plate 4 is used as the first combination direction between the two first tool boxes 1.

[0074] The first limit clamp 6 is arranged on the bottom surface of the first tool box 1. After the two first tool boxes 1 are combined along the first combination direction, the first limit clamp 6 on the upper first tool box 1 can cooperate with the first limit groove 3 on the lower first tool box 1 to limit the relative position between the two first tool boxes 1. A first limit clamp 6 is arranged at the relative position of each first limit groove 3 on the bottom surface of the first tool box 1 and the top surface of the first tool box 1.

[0075] The first limit clamp 6 is composed of two connected connecting plates. One end of one connecting plate facing away from the other connecting plate is connected to the bottom surface of the first toolbox 1, and the surface where the connecting plate is located intersects with the surface where the bottom surface of the first toolbox 1 is located; the surface where the other connecting plate is located is parallel to the surface where the bottom surface of the first toolbox 1 is located. The two connecting plates form a structure with an obtuse angle. When the two first toolboxes 1 are combined along the first combination direction, the connecting plate in the first limit clamp 6 that is parallel to the bottom surface of the first toolbox 1 is completely moved into the first limit groove 3, and the connecting plate in the first limit clamp 6 that is parallel to the bottom surface of the first toolbox 1 is clamped by the two first ear plates 4 on the first limit groove 3, thereby realizing the limitation of the relative position between the two first toolboxes 1. Specifically, the first limit clamp 6 and the first toolbox 1 are detachably connected. Preferably, three screws are used to fix the first limit clamp 6 to the corresponding position of the first toolbox 1.

[0076] A first receiving groove 12 is opened on the bottom surface of the first tool box 1, and the first receiving groove 12 is located on the side of the first tool box 1 away from the two first ear plates 4 of the first limiting groove 3, and the first elastic fixing member 2 is installed in the first receiving groove 12; a first card slot 5 is opened on the top surface of the first tool box 1, and the first card slot 5 is arranged close to the side of the top surface of the first tool box 1 away from the two first ear plates 4 of the first limiting groove 3; the first receiving groove 12 is directly below the first card slot 5.

[0077] One end of the above-mentioned first elastic fixing member 2 is an elastic end and the other end is a clamping end 9. The elastic end contacts the bottom of the first accommodating groove 12, and the relative position of the first elastic fixing member 2 in the first accommodating groove 12 is changed by the deformation of the elastic end. When the elastic end does not undergo elastic deformation, the clamping end 9 of the first elastic fixing member 2 extends out of the first accommodating groove 12.

[0078] Specifically, the elastic end of the first elastic fixing member 2 is three elastic sheets 7 arranged at intervals and staggered, and the three elastic sheets 7 can be elastically deformed after being compressed and return to their original state when there is no pressure. A first operating part 8 is formed by slotting in the middle of the first elastic fixing member 2 along its width direction. A first operating window 11 is opened on one side of the first tool box 1 adjacent to the first receiving groove 12, and the first operating window 11 is connected to the first receiving groove 12, and the first operating part 8 extends partly toward one side of the first operating window 11 into the first operating window 11. That is, the first elastic fixing member 2 is always in the first receiving groove 12 through the part of the first operating part 8 extending into the first operating window 11, and when the first tool box 1 is used alone, the first elastic fixing member 2 cannot fall from the first receiving groove 12 to the external environment. In addition, in the embodiment, the length of the first operating window 11 in the height direction is greater than the length of the first operating part 8 in the height direction, that is, the size of the first operating window 11 in the height direction is the range in which the first operating part 8 can move in the vertical direction.

[0079] In the initial state, the first operating portion 8 of the first elastic fixing member 2 is at the bottom of the first operating window 11, and the snap-on end 9 of the first elastic fixing member 2 extends to the outside of the first receiving groove 12. When the two first toolboxes 1 are combined along the first combination direction, the first elastic fixing member 2 is still in the initial state, and the first receiving groove 12 of the first toolbox 1 at the top and the first snap-on groove 5 of the first toolbox 1 at the bottom form a first receiving cavity. At this time, the first elastic fixing member 2 is in the first receiving cavity, and the snap-on end 9 of the first elastic fixing member 2 is located in the first snap-on groove 5 of the first toolbox 1 at the bottom, and a snap-on relationship is formed between the snap-on end 9 and the first snap-on groove 5, that is, the first limit assembly cooperates with the first elastic fixing member 2 to achieve the connection and fixation between the two first toolboxes 1. The operator manually lifts the first operating part 8, so that the first elastic fixing member 2 moves upward, the elastic end is deformed by force, and the clamping end 9 moves at the same time until the clamping end 9 is completely in the first accommodating groove 12, thereby releasing the clamping relationship between the clamping end 9 of the first elastic fixing member 2 of the first toolbox 1 on the upper side and the first clamping groove 5 of the first toolbox 1 on the lower side. At this time, the upper first toolbox 1 can be moved in the opposite direction of the first combination direction, and the limit between the two first toolboxes 1 can be released.

[0080] In this embodiment, a chamfer 10 is set on one side of the top surface of the first tool box 1 adjacent to the first card slot 5. When the two first tool boxes 1 are combined along the first combination direction, the first limit clamp 6 moves into the first limit slot 3 along the first combination direction, and the clamping end 9 of the first elastic fixing member 2 of the upper first tool box 1 will contact the edge of the top surface of the lower first tool box 1 during the movement, and the clamping end 9 is gradually squeezed along the chamfer 10, so that the elastic end is deformed, until the bottom surface of the upper first tool box 1 is completely in contact with the top surface of the lower first tool box 1, and the clamping end 9 is completely in the first receiving groove 12 of the upper first tool box 1. When the first limit clamp 6 is completely in the first limit slot 3, the first receiving groove 12 of the upper first tool box 1 is aligned with the first card slot 5 of the lower first tool box 1 to form a first receiving cavity, and at the same time, the clamping end 9 of the upper first tool box 1 will return to the initial state and be clamped with the first card slot 5 of the lower first tool box 1, and at this time, the two first tool boxes 1 are stacked in combination. The chamfer 10 is provided to facilitate the automatic deformation of the clamping end 9 of the upper first toolbox 1 during the combination of the two first toolboxes 1 without manual operation. That is, while the first limiting clamp 6 and the first limiting groove 3 are limiting, the clamping between the first elastic fixing member 2 and the first clamping groove 5 can be automatically realized, that is, the operator can complete the combination and stacking of the two first toolboxes 1 by pushing the upper first toolbox 1 along the first combination direction, which is very convenient to operate. Preferably, the side of the clamping end 9 of the first elastic fixing member 2 facing the inside of the first toolbox 1 is a slope, which can cooperate with the chamfer 10 on the edge of the first toolbox 1, and can more conveniently realize the automatic deformation of the clamping end 9 of the first elastic fixing member 2.

[0081] In this embodiment, the length and width of each first tool box 1 are the same, and the height of each first tool box 1 can be any height. That is, the height of the first tool box 1 is not limited, and any number of layers of first tool boxes 1 of different heights can be stacked, so that this embodiment has the beneficial effect of a wide range of applications.

[0082] The present embodiment further comprises a second tool box 13 , on which a second limiter assembly and a second elastic fixing member 31 are provided. The second limiter assembly has the same structure as the first limiter assembly, and the second elastic fixing member 31 has the same structure as the first elastic fixing member 2 .

[0083] The second limiting assembly includes at least one second limiting groove 27 and at least one second limiting clamp 30. The second limiting groove 27 is provided on the top surface of the second tool box. Second ear plates 28 are provided at any two adjacent corners of the second limiting groove 27. The direction from the side of the second limiting groove 27 away from the two second ear plates 28 to the side close to the second ear plates 28 is taken as the second combination direction. The second combination direction realizes the combination of two second tool boxes 13 or the combination of a first tool box 1 and a second tool box 13.

[0084] The second limit clamp 30 is arranged on the bottom surface of the second tool box 13. After the two second tool boxes 13 or a first tool box 1 and a second tool box 13 are combined along the second combination direction, the second limit clamp 30 on the tool box at the top can cooperate with the first limit groove 3 or the second limit groove 27 on the tool box at the bottom, so that the relative position between the two second tool boxes 13 or a first tool box 1 and a second tool box 13 is limited. A second limit clamp 30 is arranged at the relative position of each second limit groove 27 on the bottom surface of the second tool box 13 and the top surface of the second tool box 13.

[0085] The second limit clamp 30 has the same structure as the first limit clamp 6. The second limit clamp 30 is composed of two connected connecting plates. One end of one connecting plate facing away from the other connecting plate is connected to the bottom surface of the second tool box 13, and the surface of the connecting plate intersects with the surface of the bottom surface of the second tool box 13; the surface of the other connecting plate is parallel to the surface of the bottom surface of the second tool box 13. The two connecting plates form a structure with an obtuse angle. When the two second tool boxes 13 are combined along the second combination direction or one second tool box 13 is combined with one first tool box 1 along the second combination direction, the connecting plate in the second limit clamp 30 parallel to the bottom surface of the second tool box 13 is completely moved into the first limit groove 3 or the second limit groove 27, and the connecting plate in the second limit clamp 30 parallel to the bottom surface of the second tool box 13 is clamped by the two first ear plates 4 on the first limit groove 3 or the two second ear plates 28 on the second limit groove 27, thereby realizing the limitation of the relative position between the two second tool boxes 13 or one second tool box 13 and one first tool box 1. Specifically, the second position-limiting fixture 30 is detachably connected to the second tool box 13. Preferably, three screws are used to fix the second position-limiting fixture 30 at a corresponding position of the second tool box 13.

[0086] A second accommodating groove is opened on the bottom surface of the second tool box 13, and the second accommodating groove is located on the side of the second tool box 13 away from the two second ear plates 28 of the second limiting groove 27, and the second elastic fixing member 31 is installed in the second accommodating groove; a second clamping groove 29 is opened on the top surface of the second tool box 13, and the second clamping groove 29 is arranged close to the side of the top surface of the second tool box 13 away from the two second ear plates 28 of the second limiting groove 27; the second accommodating groove is directly below the second clamping groove 29.

[0087] One end of the second elastic fixing member 31 is an elastic end and the other end is a clamping end. The elastic end contacts the bottom of the second accommodating groove, and the relative position of the second elastic fixing member 31 in the second accommodating groove is changed by the deformation of the elastic end. When the elastic end does not undergo elastic deformation, the clamping end of the second elastic fixing member 31 extends out of the second accommodating groove.

[0088] Specifically, the second elastic fixing member 31 has the same structure as the first elastic fixing member 2. The elastic end of the second elastic fixing member 31 is three elastic sheets 7 arranged at intervals and staggered, and the three elastic sheets 7 can be elastically deformed after being compressed and return to their original state when there is no pressure. The second elastic fixing member 31 is slotted in the middle part along its width direction to form a second operating part. A second operating window is opened on one side of the second tool box 13 adjacent to the second receiving groove, and the second operating window is connected to the second receiving groove, and the second operating part extends partly toward the second operating window to the second operating window. That is, the second elastic fixing member 31 is always in the second receiving groove through the part extending into the second operating window by the second operating part, and when the second tool box 13 is used alone, the second elastic fixing member 31 cannot fall from the second receiving groove to the external environment. In addition, in the embodiment, the length of the second operating window in the height direction is greater than the length of the second operating part in the height direction, that is, the size opened in the height direction of the second operating window is the range in which the second operating part can move in the vertical direction.

[0089] In the initial state, the second operating portion of the second elastic fixing member 31 is at the bottom of the second operating window, and the snap-in end of the second elastic fixing member 31 extends to the outside of the second receiving groove. When the two second toolboxes 13 are combined along the second combination direction or a second toolbox 13 is combined with a first toolbox 1, the second elastic fixing member 31 is still in the initial state, and the second receiving groove of the second toolbox 13 at the top and the first snap-in groove 5 or the second snap-in groove 29 of the toolbox at the bottom form a second receiving cavity. At this time, the second elastic fixing member 31 is in the second receiving cavity, and the snap-in end of the second elastic fixing member 31 is located in the first snap-in groove 5 or the second snap-in groove 29 of the toolbox at the bottom, and a snap-in relationship is formed between the snap-in end of the second elastic fixing member 31 and the first snap-in groove 5 or the second snap-in groove 29, that is, the second limit assembly cooperates with the second elastic fixing member 31 to realize the connection and fixation between the two second toolboxes 13 or a second toolbox 13 and a first toolbox 1. The operator manually lifts the second operating part, so that the second elastic fixing piece 31 moves upward, the elastic end is deformed by force, and the clamping end moves until the clamping end is completely in the second accommodating groove, thereby releasing the clamping relationship between the second elastic fixing piece 31 of the second toolbox 13 at the top and the first clamping groove 5 or the second clamping groove 29 of the toolbox at the bottom. At this time, the second toolbox 13 at the top can be moved in the opposite direction of the second combination direction, and the limit between the two second toolboxes 13 or a second toolbox 13 and a first toolbox 1 can be released.

[0090] In this embodiment, a chamfer 10 is provided on one side of the top surface of the second toolbox 13 adjacent to the second clamping groove 29. When two second toolboxes 13 or one second toolbox 13 and one first toolbox 1 are combined along the second combination direction, the second limit clamp 30 moves along the second combination direction into the second limit groove 27 or the first limit groove 3, and the clamping end of the second elastic fixing member 31 of the upper second toolbox 13 will contact the top surface edge of the lower first toolbox 1 or the second toolbox 13 during the movement, and the clamping end of the second elastic fixing member 31 is gradually squeezed along the chamfer 10, causing the elastic end to deform, until the bottom surface of the upper second toolbox 13 is completely in contact with the top surface of the lower toolbox, and the clamping end 9 of the second elastic fixing member 31 will be completely in the second receiving groove of the upper second toolbox 13. When the second limiting clamp 30 is completely in the first limiting groove 3 or the second limiting groove 27, the second receiving groove of the upper second toolbox 13 is aligned with the first clamping groove 5 or the second clamping groove 29 of the lower toolbox to form a second receiving cavity, and at the same time, the clamping end of the upper second toolbox 13 will return to the initial state and be clamped with the first clamping groove 5 or the second clamping groove 29 of the lower toolbox. At this time, two second toolboxes 13 or one second toolbox 13 and one first toolbox 1 are stacked in combination. The chamfer 10 is provided to facilitate the clamping end of the upper second toolbox 13 to automatically deform during the combination of two second toolboxes 13 or one second toolbox 13 and one first toolbox 1 without manual operation. That is, while the second limiting clamp 30 is limiting the first limiting groove 3 or the second limiting groove 27, the second elastic fixing member 31 can be automatically connected to the first clamping groove 5 or the second clamping groove 29, that is, the operator can push the upper second tool box 13 along the second combination direction to complete the combination and stacking of two second tool boxes 13 or one second tool box 13 and one first tool box 1, which is very convenient to operate. Preferably, the side of the clamping end of the second elastic fixing member 31 facing the inside of the second tool box 13 is an inclined surface, which can cooperate with the chamfer 10 of the edge of the second tool box 13, and can more conveniently realize the automatic deformation of the clamping end of the second elastic fixing member 31.

[0091] In this embodiment, the length of the second toolbox 13 is the same as the width of the first toolbox 1, and the width of the second toolbox 13 is half the length of the first toolbox 1. The second toolbox 13 has two sizes, each of which has the same length and width, and the height of one second toolbox 13 is twice the height of the other second toolbox 13. The second toolbox 13 is provided with two sizes in order to better place some tools. Two second toolboxes 13 of smaller sizes are stacked up and down to be the same height as a second toolbox 13 of larger size. That is, if Fig.11As shown, the top surface of the first toolbox 1 can be combined with two second toolboxes 13 at the same time, and the second toolboxes 13 of two sizes can be combined with the first toolbox 1, and the two second toolboxes 13 can be freely combined with each other up and down.

[0092] Preferably, four first limiting grooves 3 are arranged on the top surface of the first toolbox 1, and the four first limiting grooves 3 are arranged near the four corners, and a long groove is opened in the middle of the top surface of the first toolbox 1; four first limiting clamps 6 are arranged on the bottom surface of the first toolbox 1, and the setting positions of the four first limiting clamps 6 are matched with the setting positions of the first limiting grooves 3, and two protrusions are arranged in the middle of the bottom surface of the first toolbox 1, and when the two first toolboxes 1 are combined together, the two protrusions are located in the long groove opened on the top surface of the first toolbox 1. Two limiting grooves 3 are arranged on the top surface of the second toolbox 13, and the middle part is grooved, and two second limiting clamps 30 are arranged on the bottom surface of the second toolbox 13, and the setting positions of the two second limiting clamps 30 are matched with the setting positions of the second limiting groove 27, and a protrusion is arranged in the middle of the bottom surface of the second toolbox 13, and when the two second toolboxes 13 are stacked up and down, the protrusion is in the groove, and the second limiting clamp 30 is in the second limiting groove 27. When the two second tool boxes 13 are placed side by side, the bottom surface structure is completely matched with the top surface structure of the first tool box 1 .

[0093] This embodiment also includes a rod tool box 14 , and a side wall of the rod tool box 14 is provided with two sleeve structures 16 . A door-shaped rod 15 is installed at the two sleeve structures 16 . The two long sides of the rod 15 can reciprocate axially along the two sleeve structures 16 .

[0094] The locking and adjusting mechanism 17 is horizontally arranged at the ends of the two sleeve structures 16. The locking and adjusting mechanism 17 includes two sliding sleeves 18, a base 19, a shell 20, a limit locking member 21, and a pressing portion 22. The sliding sleeve 18 is arranged on the sleeve structure 16, and the sliding sleeve 18 is slidably connected to the sleeve structure 16. The base 19 is arranged between the two sliding sleeves 18 and connected to the two sliding sleeves 18. The shell 20 is covered on the base 19, and the shell 20 and the base 19 form a third accommodating cavity, the limit locking member 21 is in the third accommodating cavity, and a through hole is provided in the middle of the top surface of the shell 20. The pressing portion 22 is in the third accommodating cavity, and a part of it is exposed to the external environment from the through hole, and the pressing portion 22 is above the limit locking member 21; the pressing portion 22 is slidably connected to the shell 20, and the pressing portion 22 can move along the height direction of the shell 20.

[0095] The above-mentioned limiting locking member 21 is composed of a spring 23, two first wedge blocks 24, two connecting rods 25, and two limiting blocks 26. A first wedge block 24 is respectively provided at both ends of the spring 23, and the inclined surfaces of the first wedge blocks 24 are both away from the spring 23. A connecting rod 25 is provided on the side of the first wedge block 24 away from the spring 23, and a limiting block 26 is provided on the side of the connecting rod 25 away from the first wedge block 24. The middle part of the bottom surface of the pressing portion 22 is recessed inward to form a trapezoidal groove structure.

[0096] like Fig.18 As shown, two positioning holes 33 are provided on the inner sides of the two long sides of the pull rod 15 , and the distance between the two positioning holes 33 is the moving stroke of the pull rod 15 .

[0097] like Fig.21 As shown, a plurality of guide ribs 32 are provided inside the base 19 to prevent the connecting rod 25 from shifting during movement, causing the limit block 26 to be unable to align with the through hole opened on the sleeve structure 16 for the limit block 26 to pass through.

[0098] In the initial state, the pressing portion 22 is not subjected to force and is squeezed outward by the spring 23, pushing the two first wedge blocks 24 outward, so that the pressing portion 22 is pushed upward, and at the same time drives the limit block 26 on the connecting rod 25 to penetrate the sleeve structure 16 and rest on the long side of the pull rod 15, so that the limit locking member 21 limits the relative position between the pull rod 15 and the sleeve structure 16.

[0099] When the relative position between the pull rod 15 and the sleeve structure 16 needs to be adjusted, the pressing part 22 is pressed to move the pressing part 22 toward the limit locking member 21 along the height direction of the shell 20. The trapezoidal groove structure at the bottom of the pressing part 22 abuts against the inclined surfaces of the two first wedge blocks 24, and squeezes the two first wedge blocks 24 inward, driving the two limit blocks 26 away from the pull rod 15 to release the lock on the pull rod 15. The pull rod 15 can be dragged and adjusted to the desired position, and the pressing part 22 can be released to lock it again.
