When adjusting the length of some existing telescopic handles, the movable rod needs to be unlocked and locked, and the locking action is relatively cumbersome, resulting in inconvenience in adjusting the length. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a telescopic handle assembly that can conveniently adjust and lock its own telescopic length.

[0004] The present invention also provides a pair of gardening shears having the telescopic handle assembly.

[0005] According to the first aspect of the present invention, the telescopic handle assembly comprises an outer sleeve, an inner sleeve, a clamp and a rotary switch; the inner sleeve is movably inserted in the outer sleeve; the clamp is connected to the outer sleeve, the clamp is sleeved on the outer periphery of the inner sleeve, the clamp is provided with a first notch communicating with the inner cavity of the clamp, the outer side wall of the clamp is provided with two hinge seats, the hinge seats are arranged on both sides of the first notch, and the two hinge seats can approach each other to make the clamp elastically deform to lock the inner sleeve; the rotary switch is rotatably connected with the hinge seat; wherein the rotary switch is provided with at least one first inclined surface, and the outer side wall of the hinge seat is provided with at least one second inclined surface, and the first inclined surface and the second inclined surface are matched one by one; when the rotary switch rotates forward, the first inclined surface and the second inclined surface squeeze each other to make the two hinge seats approach each other; when the rotary switch rotates reversely, the clamp is elastically deformed to make the two hinge seats move away and return.

[0006] The telescopic handle assembly according to the embodiment of the present invention has at least the following beneficial effects: the inner sleeve is movably inserted into the outer sleeve, so that the inner sleeve and the outer sleeve can control the overall length of the handle assembly by telescoping each other. When the outer sleeve and the inner sleeve need to be locked, the rotary switch is first rotated to squeeze the first inclined surface and the second inclined surface against each other, so that the two hinged seats are close to each other, driving the clamp to undergo elastic deformation to shrink inward, so that the clamp locks the inner sleeve and fixes the inner sleeve and the outer sleeve to each other; on the contrary, to make the outer sleeve and the inner sleeve telescopic, it is only necessary to rotate the rotary switch in the opposite direction to reset the first inclined surface and the second inclined surface, so that the clamp can also return to its original size, thereby unlocking the inner sleeve, thereby the relative position of the outer sleeve and the inner sleeve can be arbitrarily adjusted to adjust the overall length of the handle assembly, and at the same time, with the elastic potential energy of the elastic deformation of the clamp, the clamp can drive the two hinged seats to reset. The process of unlocking and locking the inner sleeve only requires rotating the rotary switch, which facilitates the process of adjusting the length of the handle assembly itself.

The bolt can be inserted into the first fixing hole and the second fixing hole to connect the rotary switch with the hinge seat, and the rotary switch is rotated around the bolt to realize the rotational connection of the rotary switch.

[0011] According to some embodiments of the present invention, a connecting sleeve is provided between the clamp and the outer sleeve, the connecting sleeve is fixed to the outer sleeve, and the clamp is connected to the outer sleeve via the connecting sleeve.

[0012] According to some embodiments of the present invention, the connecting sleeve is detachably connected to the outer sleeve, which facilitates the disassembly and assembly of the connecting sleeve and the clamp, and the connecting sleeve and the clamp can be easily replaced or maintained by disassembling the connecting sleeve.

[0013] According to some embodiments of the present invention, the inner side wall of the connecting sleeve is provided with a clamping column, and the outer sleeve is provided with a clamping groove that is clamped with the clamping column. The clamping cooperation between the clamping column and the clamping groove realizes a detachable connection between the connecting sleeve and the outer sleeve.

[0014] According to some embodiments of the present invention, a swing arm is provided at one end of the rotary switch away from the second notch, a avoidance groove is provided on the lower side of the swing arm, and an opening connected to the avoidance groove is provided at the end of the swing arm. By providing the avoidance groove and the opening, the rotation of the rotary switch is facilitated.

[0015] According to some embodiments of the present invention, a gripping sleeve is further included, and the gripping sleeve is sleeved on the outer sleeve. By providing the gripping sleeve, it is convenient to grip the telescopic handle assembly, and the gripping comfort of the telescopic handle assembly is improved.

[0016] The gardening shears according to the second embodiment of the present invention include the telescopic handle assembly according to the first embodiment of the present invention.

[0017] According to the embodiment of the present invention, the gardening shears have at least the following beneficial effects: the gardening shears include a telescopic handle assembly, wherein the inner sleeve is movably inserted into the outer sleeve, so that the inner sleeve and the outer sleeve can control the overall length of the handle assembly by telescoping each other. When the outer sleeve and the inner sleeve need to be locked, the rotary switch is first rotated to make the first inclined surface and the second inclined surface squeeze each other, so that the two hinge seats are close to each other, driving the clamp to undergo elastic deformation to shrink inward, so that the clamp locks the inner sleeve, so that the inner sleeve and the outer sleeve are fixed to each other; on the contrary, to make the outer sleeve and the inner sleeve telescopic, it is only necessary to rotate the rotary switch in the opposite direction to reset the first inclined surface and the second inclined surface, so that the clamp can also return to its original size, thereby unlocking the inner sleeve, thereby the relative position of the outer sleeve and the inner sleeve can be arbitrarily adjusted to adjust the overall length of the handle assembly, and at the same time, with the elastic potential energy of the elastic deformation of the clamp, the clamp can drive the two hinge seats to reset. The process of unlocking and locking the inner sleeve only requires rotating the rotary switch, which facilitates the process of adjusting the length of the handle assembly itself.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the telescopic handle assembly according to the first embodiment of the present invention includes an outer kit 100, an inner kit 200, a clamp 300 and a rotary switch 400; the inner kit 200 is movably inserted in the outer kit 100; the clamp 300 is connected to the outer kit 100, and the clamp 300 is sleeved on the outer periphery of the inner kit 200. The clamp 300 is provided with a first notch 310 connected to the inner cavity of the clamp 300, and the outer side wall of the clamp 300 is provided with two hinge seats 320, which are respectively arranged on both sides of the first notch 310, and the two hinge seats 320 can be close to each other so that the clamp 3 00 elastically deforms to lock the inner kit 200; the rotary switch 400 is rotatably connected to the hinge seat 320; wherein, the rotary switch 400 is provided with at least one first inclined surface 422, and the outer side wall of the hinge seat 320 is provided with at least one second inclined surface 332, and the first inclined surface 422 and the second inclined surface 332 are matched one by one; when the rotary switch 400 rotates forward, the first inclined surface 422 and the second inclined surface 332 squeeze each other to make the two hinge seats 320 approach each other; when the rotary switch 400 rotates reversely, the clamp 300 is elastically deformed to make the two hinge seats 320 move away and return.

[0036] Specifically, the inner kit 200 is movably inserted into the outer kit 100, so that the inner kit 200 and the outer kit 100 can control the overall length of the handle assembly by telescoping each other. When the outer kit 100 and the inner kit 200 need to be locked, the rotary switch 400 is first rotated to squeeze the first inclined surface 422 and the second inclined surface 332 against each other, so that the two hinge seats 320 are close to each other, driving the clamp 300 to undergo elastic deformation to shrink inward, so that the clamp 300 locks the inner kit 200, so that the inner kit 200 and the outer kit 100 are fixed to each other. On the contrary, to make the outer set 100 and the inner set 200 telescopic, it is only necessary to rotate the rotary switch 400 in the opposite direction to reset the first inclined surface 422 and the second inclined surface 332, and the clamp 300 can be restored to its original size through elastic deformation, thereby unlocking the inner set 200, so that the relative position of the outer set 100 and the inner set 200 can be adjusted arbitrarily to adjust the overall length of the handle assembly. At the same time, with the elastic potential energy of the elastic deformation of the clamp 300, the clamp 300 can drive the two hinge seats 320 to move away and reset. The process of unlocking and locking the inner set 200 only requires rotating the rotary switch 400, which facilitates the process of adjusting the length of the handle assembly itself.

[0037] Among them, the first bevel 422 and the second bevel 332 can be located on the rotating shaft of the rotary switch 400. The rotary switch 400 rotates to change the relative contact position of the first bevel 422 and the second bevel 332, thereby overcoming the elastic force of the clamp 300 to make the two hinged seats 320 approach each other. At the same time, the clamp 300 contracts inwardly to achieve the effect of locking the inner kit 200.

[0038] In some embodiments of the present invention, both the inner sleeve 100 and the outer sleeve 200 can be configured in a tubular shape, wherein the inner sleeve 100 can also be configured in a solid rod shape.

[0039] In some embodiments of the present invention, the rotary switch 400 is provided with a second notch 410 that is clamped and matched with the two hinge seats 320, the two hinge seats 320 are respectively fitted with the opposite side walls of the second notch 410, the inner side wall of the second notch 410 is rotatably connected with the hinge seat 320, and the opposite side walls of the second notch 410 are each provided with at least one first inclined surface 422. By providing the second notch 410, the first inclined surface 422 and the second inclined surface 332 are more tightly fitted, and the transmission efficiency is higher, so that the movement amplitude of the rotary switch 400 can be reduced, and the locking efficiency of the rotary switch 400 on the clamp 300 can be improved.

[0040] It is easy to imagine that in other embodiments, the rotary switch 400 may not be provided with the second notch 410. The rotary switch 400 is located on one side of an articulated seat 320. A first inclined surface 422 cooperating with the second inclined surface 332 is provided on a side wall of the rotary switch 400. Then, a bolt can be passed through the rotary switch 400 and the articulated seat 320 and fastened with a nut to make the first inclined surface 422 fit with the second inclined surface 332. By rotating the rotary switch 400, the first inclined surface 422 and the second inclined surface 332 can also be squeezed against each other, thereby driving the two articulated seats 320 close to each other, so that the clamp 300 locks the inner kit 200.

[0041] In some embodiments of the present invention, at least one first wedge block 421 is provided on the inner side wall of the second notch 410, and the first inclined surface 422 is provided on the first wedge block 421; at least one second wedge block 331 is provided on the outer side wall of the hinge seat 320 to correspond to the first wedge block 421, and the second inclined surface 332 is provided on the second wedge block 331. The first wedge block 421 and the second wedge block 331 can cooperate with each other, so that when the rotary switch 400 rotates, the first inclined surface 422 and the second inclined surface 332 can be pressed against each other. Specifically, as Figure 3 As shown, the second notch 410 has two oppositely arranged side walls, which are the inner side walls of the second notch 410. Two first wedge blocks 421 are arranged on each inner side wall. The two first wedge blocks 421 are distributed around the rotating shaft of the rotary switch 400. The outer side wall of the hinge seat 320 is provided with a second wedge block 331 corresponding to the first wedge block 421. During the rotation of the rotary switch 400, the first wedge block 421 and the second wedge block 331 move relative to each other, so that the raised part of the first wedge block 421 and the raised part of the second wedge block 331 contact and fit, so that the first inclined surface 422 and the second inclined surface 332 are squeezed against each other, and the two hinge seats are pushed inward, so that the clamp 300 locks the inner kit 200.

[0042] Of course, in other embodiments, the number of the first wedge block 421 and the number of the second wedge block 331 may be one or more than two respectively, and the specific number may be set accordingly according to the actual application and is not limited here.

[0043] In addition, the first wedge block 421 can be injection molded with the rotary switch 400 as an integral structure, and the second wedge block 331 can be injection molded with the hinge seat 320 as an integral structure, which facilitates the processing of the first wedge block 421 and the second wedge block 331.

[0044] It is understandable that in other embodiments, the first slope 422 can also be formed by opening an inclined groove on the inner wall of the second notch 410 . Similarly, the second slope 332 can also be formed by opening an inclined groove on the outer wall of the hinge seat 320 .

[0045] In some embodiments of the present invention, the inner wall of the second notch 410 is provided with a convex shaft 420, the outer wall of the hinge seat 320 is provided with a circular groove 330 that is rotatably matched with the convex shaft 420, the first inclined surface 422 is provided on the convex shaft 420, and the second inclined surface 332 is provided on the circular groove 330; through the cooperation between the convex shaft 420 and the circular groove 330, the rotary switch 400 can rotate relative to the two hinge seats 320, thereby realizing the rotary connection of the rotary switch 400. Among them, the first wedge block 421 in the above embodiment can be provided on the convex shaft 420 and form an integral structure with the convex shaft 420, and the second wedge block 331 can be provided in the circular groove 330 and form an integral structure with the inner end wall of the circular groove 330, so that the structure of the rotary switch 400 and the hinge seat 320 is more compact, and the mutual cooperation between the first inclined surface 422 and the second inclined surface 332 is more efficient.

[0046] It is easy to imagine that in other embodiments, the inner wall of the second notch 410 is provided with a circular groove 330, the outer wall of the hinge seat 320 is provided with a convex shaft 420 rotatably matched with the circular groove 330, the first inclined surface 422 is provided on the circular groove 330, and the second inclined surface 332 is provided on the convex shaft 420.

[0047] In some embodiments of the present invention, the inner wall of the second notch 410 is provided with a first fixing hole 440 for the rod of the bolt 700 to pass through, and the outer wall of the hinge seat 320 is provided with a second fixing hole 340 for the rod of the bolt 700 to pass through. The bolt 700 can be inserted into the first fixing hole 440 and the second fixing hole 340 to connect the rotary switch 400 with the hinge seat 320, and the rotary switch 400 is rotated around the bolt 700 to achieve the rotary connection of the rotary switch 400. Specifically, as Figure 3 As shown, the first fixing hole 440 is arranged on the convex shaft 420, and the first wedge block 421 is arranged on the end wall of the first fixing hole 440 to ensure that the first wedge block 421 can rotate around the rotating shaft of the rotary switch 400, and the second fixing hole 340 is arranged in the circular groove 330, and the second wedge block 331 is arranged on the end wall of the second fixing hole 340 to ensure that the second wedge block 331 can cooperate with the first wedge block 421.

[0048] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, a connecting sleeve 500 is provided between the clamp 300 and the outer sleeve 100, and the connecting sleeve 500 is fixed to the outer sleeve 100, and the clamp 300 is connected to the outer sleeve 100 through the connecting sleeve 500. Among them, the connecting sleeve 500 and the clamp 300 can be formed into an integral structure to facilitate the processing of the two.

[0049] In some embodiments of the present invention, the connecting sleeve 500 is detachably connected to the outer sleeve 100, which facilitates the disassembly and assembly of the connecting sleeve 500 and the clamp 300, and the connecting sleeve 500 and the clamp 300 can be easily replaced or maintained by disassembling the connecting sleeve 500.

[0050] Further, in some embodiments of the present invention, Figure 6 As shown, the inner side wall of the connecting sleeve 500 is provided with a clamping column 510, and the outer sleeve 100 is provided with a clamping groove 110 that is clamped and matched with the clamping column 510. The clamping column 510 and the clamping groove 110 are clamped and matched to realize the detachable connection between the connecting sleeve 500 and the outer sleeve 100. It is conceivable that in other embodiments, the connecting sleeve 500 and the outer sleeve 100 can also be connected by screw connection, for example, an internal thread is provided on the inner cavity wall of the connecting sleeve 500, and an external thread is provided on the outer side wall of the outer sleeve 100, and the outer sleeve 100 and the connecting sleeve 500 are detachably matched by the internal thread and the external thread.

[0051] In some embodiments of the present invention, Figure 4 and Figure 6 As shown, a swing arm 450 is provided at one end of the rotary switch 400 away from the second notch 410, a avoidance groove 430 is provided on the lower side of the swing arm 450, and an opening 431 connected to the avoidance groove 430 is provided at the end of the swing arm 450. By setting the avoidance groove 430 and the opening 431, the rotation of the rotary switch 400 is facilitated. In actual application, the finger can be inserted into the avoidance groove 430 through the opening 431 to push the swing arm 450 upward, thereby driving the rotary switch 400 to rotate.

[0052] In some embodiments of the present invention, Figure 2 As shown, it also includes a gripping sleeve 600, which is sleeved on the outer sleeve 100. By providing the gripping sleeve 600, it is convenient to hold the telescopic handle assembly, and the gripping comfort of the telescopic handle assembly is improved.

[0053] like Figure 7 As shown, the gardening shears according to the second embodiment of the present invention include the telescopic handle assembly of the first embodiment of the present invention.

[0054] Specifically, the gardening shears include a telescopic handle assembly, wherein the inner set 200 is movably inserted into the outer set 100, so that the inner set 200 and the outer set 100 can control the overall length of the handle assembly by telescoping each other. When the outer set 100 and the inner set 200 need to be locked, the rotary switch 400 is first rotated to squeeze the first inclined surface 422 and the second inclined surface 332 against each other, so that the two hinge seats 320 are close to each other, driving the clamp 300 to undergo elastic deformation to shrink inward, so that the clamp 300 locks the inner set 200, so that the inner set 2 00 and the outer set 100 are fixed to each other; on the contrary, to make the outer set 100 and the inner set 200 telescopic, it is only necessary to rotate the rotary switch 400 in the opposite direction to reset the first inclined surface 422 and the second inclined surface 332, so that the clamp 300 can also return to its original size, thereby unlocking the inner set 200, thereby the relative position of the outer set 100 and the inner set 200 can be adjusted arbitrarily to adjust the overall length of the handle assembly, and at the same time, with the elastic potential energy of the elastic deformation of the clamp 300, the clamp 300 can drive the two hinge seats 320 to reset. The process of unlocking and locking the inner set 200 only requires rotating the rotary switch 400, which facilitates the process of adjusting the length of the handle assembly itself.

[0055] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the gardening shears also include a first shearing body 810, a second shearing body 820, a connecting rod 830 and a transmission rod 840. The first shearing body 810 and the transmission rod 840 are both provided with a telescopic handle assembly. The middle part of the first shearing body 810 is hinged to the middle part of the second shearing body 820. Corresponding shearing structures are provided between one end of the first shearing body 810 and one end of the second shearing body 820. One end of the connecting rod 830 is hinged to the middle part of the first shearing body 810, and the other end of the connecting rod 830 is hinged to the transmission rod 840. A tooth structure 850 that cooperates with each other is provided between the transmission rod 840 and the first shearing body 810. The rotation center of the tooth structure 850 on the transmission rod 840 and the rotation center of the tooth structure 850 on the first shearing body 810 respectively correspond to the hinge point of the connecting rod 830. A sliding member 841 is provided on the side of the transmission rod 840 that deviates from the intersection point, and a sliding groove 821 that slidably cooperates with the sliding member 841 is provided at the other end of the second shearing body 820.

[0056] When the two telescopic rod handle assemblies move toward each other, due to the limitation of the connecting rod 830, the transmission rod 840 and the first scissors body 810 rotate through the tooth structure 850. At this time, the first scissors body 810 can be assumed to be relatively stationary, and the force-applying end of the telescopic rod handle assembly connected to the transmission rod 840 is at the end, and the tooth structure 850 cooperating with the first scissors body 810 is located at the other end. The tooth structure 850 reacts on the sliding member 841, and the sliding member 841 slides with the slide groove 821 to drive the second scissors body 820 to move close to the first scissors body 810 to achieve the shearing effect. The present invention forms a connecting rod 830 slider structure through the first scissors body 810, the second scissors body 820, the connecting rod 830, the transmission rod 840, and the tooth structure 850, which has a good amplification effect on the force applied at the telescopic rod handle assembly, ensures smooth and labor-saving shearing, and improves the operating feel.
