Technical Field

[0001] The invention relates to the field of gardening tools, in particular to a pair of telescopic scissors. Background Art

[0002] As we all know, with the development of society and the continuous progress of science and technology, the requirements for gardening are also constantly increasing. Some of the branches, leaves, and flower paths of garden plants need to be trimmed frequently, and people use gardening scissors on a daily basis. Today's gardening scissors generally adopt the following structure, including a scissor body, which is composed of a main blade and an auxiliary blade that are cross-rotated and connected, and the rear ends of the main blade and the auxiliary blade are both provided with handles for easy grip.

[0003] Although the above-mentioned gardening shears can meet the needs of users for daily pruning of garden plants, the handles of these gardening shears are relatively short. For some taller garden plants, it is difficult for people to reach the high branches and leaves when pruning with the gardening shears. Therefore, people often need to use ladders or stools to prune the high branches and leaves, which brings certain inconvenience to people's daily pruning work.

[0004] In addition, the branches and leaves of some existing garden plants are relatively thick in diameter. When using existing gardening shears to trim them, people need to exert a lot of force to drive the gardening shears to trim them, so people's work intensity is high, time-consuming and labor-intensive. Summary of the invention

[0005] 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 scissors, the length of the handle of which can be freely adjusted according to needs, so that the overall length of the telescopic scissors can be extended to be suitable for pruning plants at higher positions.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] According to certain embodiments of the present invention, a telescopic scissors comprises a scissors body, wherein the scissors body comprises a main blade and a secondary blade, wherein the main blade and the secondary blade are arranged to rotate crosswise with each other, and the rear ends of the main blade and the secondary blade are each provided with a telescopic handle that can be extended or shortened, and the telescopic handle comprises a first handle, a second handle and a locking device, wherein the first handle is connected to the main blade or the secondary blade, the second handle is movably sleeved on the outer periphery of the first handle, the locking device is arranged on the outer surface of the second handle, the second handle can be moved away from or close to the scissors body along the length direction of the first handle, and the locking device can lock or unlock the relative position between the first handle and the second handle.

[0008] Beneficial effects of a telescopic scissors according to some embodiments of the present invention:

[0009] A telescopic scissors according to this embodiment is provided with a telescopic handle capable of extending or shortening at the rear ends of the main blade and the secondary blade of the scissors body. The telescopic handle includes a first handle and a second handle sleeved with each other, and a locking device capable of locking or unlocking the relative position between the first handle and the second handle is arranged on the outer surface of the second handle. By adopting the above structure, when the user needs to adjust the overall length of the telescopic scissors of this embodiment, the user controls the locking device to unlock the relative position between the first handle and the second handle. At this time, the second handle can move away from the scissors body along the length direction of the first handle. Then the user controls the locking device to lock the relative position between the first handle and the second handle, so that the length of the telescopic handle becomes longer, and further the overall length of the telescopic scissors becomes longer, which is convenient for the user to use the telescopic scissors of this embodiment to cut the branches, leaves or flower stems at high positions of garden plants. Moreover, since the overall length of the telescopic handle becomes longer, the driving force arm during cutting of the telescopic scissors of this embodiment becomes longer. Therefore, when the user holds the telescopic handle to drive the scissors body to cut garden plants, it can be more labor-saving, and the telescopic scissors can cut branches, leaves or flower stems with larger diameters more easily.

[0010] In some embodiments of the present invention, the locking device includes a mounting seat arranged on the outer surface of the second handle. An installation cavity is arranged inside the mounting seat, and a first pressing member capable of passing through the side wall of the second handle and abutting against the first handle is movably installed inside the installation cavity. The mounting seat is provided with an adjusting device capable of driving the first pressing member to tightly press the first handle.

[0011] In some embodiments of the present invention, the adjusting device includes an adjusting screw rod rotatably installed on the mounting seat. The adjusting screw rod is threadedly connected with a first wedge-shaped block. The first wedge-shaped block is located inside the installation cavity. A first inclined surface capable of cooperatively abutting against the first wedge-shaped block is arranged at one end of the first pressing member away from the first handle. When the adjusting screw rod rotates and the first wedge-shaped block moves along the adjusting screw rod, the first wedge-shaped block can cooperatively abut against the first inclined surface and drive the first pressing member to pass through the side wall of the second handle and squeeze the first handle.

[0012] In some embodiments of the present invention, a first elastic member is sleeved on the outer periphery of the first pressing member. One end of the first elastic member abuts against the outer surface of the mounting seat or the second handle, and the other end of the first elastic member abuts against the first pressing member.

[0013] In some embodiments of the present invention, a first strip-shaped groove capable of cooperating with the first pressing member to squeeze and lock is provided on the outer surface of the first handle. The first strip-shaped groove is arranged along the length direction of the first handle. When the first wedge block drives the first pressing member to pass through the side wall of the second handle and squeeze the first handle, the first pressing member is inserted into the first strip-shaped groove and tightly presses against the bottom wall of the first strip-shaped groove.

[0014] In some embodiments of the present invention, the adjusting screw rod has a first rod section and a second rod section. The thread rotation directions of the first rod section and the second rod section are opposite. The first wedge block is threadedly connected to the first rod section. The adjusting device includes a second pressing member movably installed in the installation cavity.

One end of the second pressing member away from the first handle is provided with a second inclined surface capable of cooperating with the second wedge block to abut. The inclination direction of the second inclined surface is opposite to the inclination direction of the first inclined surface. When the adjusting screw rod rotates and the first wedge block and the second wedge block move relatively closer or farther away, the first wedge block and the second wedge block can respectively drive the first pressing member and the second pressing member to move, so that the first pressing member and the second pressing member pass through the side wall of the second handle and squeeze the first handle.

[0015] In some embodiments of the present invention, a second elastic member is sleeved on the outer periphery of the second pressing member. One end of the second elastic member abuts against the outer surface of the mounting seat or the second handle, and the other end of the second elastic member abuts against the second pressing member.

[0016] In some embodiments of the present invention, a guiding device for guiding the relative movement of the first handle and the second handle is provided on the other side of the second handle away from the locking device.

[0017] In some embodiments of the present invention, the guiding device includes a guiding groove and a guiding post.

[0033] Figures 1 to 9 is a schematic diagram of some embodiments of a telescopic scissor of the present invention.

[0034] Refer to Figures 1 to 9 and mainly refer to Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9, A telescopic scissor according to certain embodiments of the present invention. For ease of description, it is sometimes simply referred to as "telescopic scissor" hereinafter. A telescopic scissor according to certain embodiments of the present invention includes a scissor body 100. The scissor body 100 includes a main blade 110 and a sub-blade 120. The main blade 110 and the sub-blade 120 are arranged to rotate crosswise with each other. The front ends of the main blade 110 and the sub-blade 120 are both provided with cutting edges. During the process of the front ends of the main blade 110 and the sub-blade 120 moving relatively close to each other, the cutting edges of the main blade 110 and the sub-blade 120 can move relatively close to each other and cooperate to cut an article. The rear ends of the main blade 110 and the sub-blade 120 are both provided with telescopic handles 200 that can extend or contract. In this embodiment, the telescopic handle 200 includes a first handle 210, a second handle 220, and a locking device 230. The first handle 210 and the second handle 220 are two hollow pipes. The first handle 210 is connected to the main blade 110 or the sub-blade 120. Specifically, the front end of the first handle 210 is connected to the rear end of the main blade 110, or the front end of the first handle 210 is connected to the rear end of the sub-blade 120. The second handle 220 is movably sleeved on the outer periphery of the first handle 210. The second handle 220 can move away from or close to the scissor body 100 along the length direction of the first handle 210. That is, the second handle 220 and the first handle 210 are sleeved with each other, and the second handle 220 and the first handle 210 can move relatively away from each other to make the overall length of the telescopic handle 200 longer, or the second handle 220 and the first handle 210 can move relatively close to each other and coincide to make the overall length of the telescopic handle 200 shorter. The locking device 230 is arranged on the outer surface of the second handle 220. The locking device 230 can lock or unlock the relative position between the first handle 210 and the second handle 220.

[0035] A telescopic scissor of this embodiment is provided with a telescopic handle 200 capable of extending or shortening at the rear ends of the main blade 110 and the secondary blade 120 of the scissor body 100. The telescopic handle 200 includes a first handle 210 and a second handle 220 which are sleeved with each other. A locking device 230 capable of locking or unlocking the relative position between the first handle 210 and the second handle 220 is arranged on the outer surface of the second handle 220. By adopting the above structure, when the user needs to adjust the overall length of the telescopic scissor of this embodiment, the user controls the locking device 230 to unlock the relative position between the first handle 210 and the second handle 220. At this time, the second handle 220 can move away from the scissor body 100 along the length direction of the first handle 210. Then the user controls the locking device 230 to lock the relative position between the first handle 210 and the second handle 220, so that the overall length of the telescopic handle 200 becomes longer, and further the overall length of the telescopic scissor becomes longer, which is convenient for the user to use the telescopic scissor of this embodiment to cut the branches, leaves or flower stems at high positions of garden plants. Moreover, since the overall length of the telescopic handle 200 becomes longer, the driving force arm during cutting of the telescopic scissor of this embodiment becomes longer. Therefore, when the user holds the telescopic handle 200 to drive the scissor body 100 to cut garden plants, it can be more labor-saving, and the telescopic scissor can more easily cut branches, leaves or flower stems with a larger diameter.

[0036] Refer to Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9, in order to make the structure of the telescopic scissors in this embodiment more compact, in some embodiments of the present invention, the locking device 230 includes a mounting seat 231, a first pressing member 232 and an adjusting device. The mounting seat 231 is disposed on the outer surface of the second handle 220. An installation cavity 2310 is provided inside the mounting seat 231. The first pressing member 232 is movably installed inside the installation cavity 2310 of the mounting seat 231. The first pressing member 232 can pass through the side wall of the second handle 220 and abut against the first handle 210, that is, a through hole for the first pressing member 232 to pass through is provided on the side wall of the second handle 220. The adjusting device is disposed on the mounting seat 231, and the adjusting device can drive the first pressing member 232 to tightly press the first handle 210. By adopting the above structure, when the user needs to lock the relative position between the first handle 210 and the second handle 220, the user can drive the first pressing member 232 to pass through the through hole on the side wall of the second handle 220 and press the first handle 210 through the adjusting device. At this time, the relative position between the first handle 210 and the second handle 220 is locked; when the user needs to adjust the relative position between the first handle 210 and the second handle 220, the user can remove the pressing force applied to the first pressing member 232 through the adjusting device. At this time, the first pressing member 232 no longer tightly presses the first handle 210. Therefore, the relative position between the first handle 210 and the second handle 220 is unlocked, and the user can freely drive the first handle 210 and the second handle 220 to move relative to each other, achieving the function of freely adjusting the overall length of the telescopic handle 200.

[0037] In order to simplify the structure of the adjusting device, in some embodiments of the present invention, the adjusting device includes an adjusting screw rod 233 and a first wedge block 234. The adjusting screw rod 233 is rotatably installed on the mounting base 231. The axial direction of the adjusting screw rod 233 is perpendicular to the direction in which the first pressing member 232 moves to press the first handle 210. The first wedge block 234 is threadedly connected to the adjusting screw rod 233. The first wedge block 234 is located inside the mounting cavity 2310. The first pressing member 232 is located between the first wedge block 234 and the first handle 210. One end of the first pressing member 232 away from the first handle 210 is provided with a first inclined surface 2320 that can cooperate and abut with the first wedge block 234. When the adjusting screw rod 233 rotates and the first wedge block 234 moves along the adjusting screw rod 233, the first wedge block 234 can cooperate and abut with the first inclined surface 2320 and drive the first pressing member 232 to pass through the side wall of the second handle 220 and press the first handle 210. When the user needs to unlock the relative position between the second handle 220 and the first handle 210, the user only needs to turn the adjusting screw rod 233 in the reverse direction. At this time, the adjusting screw rod 233 drives the first wedge block 234 to move away from the first inclined surface 2320 at the end of the first pressing member 232. Therefore, the first wedge block 234 removes the pressure applied to the first pressing member 232, and the first pressing member 232 no longer presses the first handle 210. At this time, the relative position between the second handle 220 and the first handle 210 is unlocked, and the user can freely adjust the relative position between the second handle 220 and the first handle 210, and the operation is simple and convenient. Moreover, since the axial direction of the adjusting screw rod 233 is perpendicular to the direction in which the first pressing member 232 moves to press the first handle 210, when the adjusting screw rod 233 drives the first wedge block 234 to cooperate and abut with the first inclined surface 2320 so that the first pressing member 232 presses the first handle 210, the adjusting screw rod 233 can lock the first wedge block 234, ensuring that the first pressing member 232 can firmly lock the relative position between the second handle 220 and the first handle 210 and is not easily loosened.

[0038] In order to make it easier for the second handle 220 to move relative to the first handle 210 when the locking device 230 unlocks the relative position between the first handle 210 and the second handle 220, in some embodiments of the present invention, a first elastic member 2321 is sleeved on the outer periphery of the first pressing member 232. Specifically, the first elastic member 2321 is a compression spring, or the first elastic member 2321 is an elastic silica gel sleeve or rubber sleeve. One end of the first elastic member 2321 abuts against the mounting seat 231 or the outer surface of the second handle 220, and the other end of the first elastic member 2321 abuts against the first pressing member 232. By adopting the above structure, when the user needs to rotate the adjusting screw 233 in the reverse direction and the first wedge block 234 removes the pressure applied to the first pressing member 232, the first elastic member 2321 can drive the first pressing member 232 to move away from the first handle 210, that is, the first pressing member 232 is separated from the outer surface of the first handle 210, thereby eliminating the friction between the first pressing member 232 and the first handle 210. Therefore, the user can better drive the second handle 220 to move relative to the first handle 210, which is more labor-saving.

[0039] Refer to Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 In order to make it difficult for the first handle 210 and the second handle 220 to swing or shake relative to each other when the user holds the telescopic handle 200 to drive the scissor body 100 to cut, in some embodiments of the present invention, a first strip-shaped groove 211 capable of cooperating with the first pressing member 232 to squeeze and lock is provided on the outer surface of the first handle 210. The first strip-shaped groove 211 is arranged along the length direction of the first handle 210, and the groove width dimension of the first strip-shaped groove 211 is adapted to the width dimension of the first pressing member 232. When the user rotates the adjusting screw 233, the adjusting screw 233 drives a wedge block 234 to move close to the first inclined surface 2320. The first wedge block 234 cooperates with and abuts against the first inclined surface 2320 and drives the first pressing member 232 to pass through the side wall of the second handle 220 and squeeze the first handle 210. The first pressing member 232 is inserted into the first strip-shaped groove 211 and tightly presses the bottom wall of the first strip-shaped groove 211. By adopting the above structure, the first pressing member 232 can not only tightly press the first handle 210 to realize the locking between the first handle 210 and the second handle 220, but also the first pressing member 232 can cooperate with the first strip-shaped groove 211 for positioning, which helps to prevent the first handle 210 and the second handle 220 from swinging or shaking relative to each other, so that the user can better hold the telescopic handle 200 to drive the scissor body 100 to cut.

[0040] Refer to Figure 5 、 Figure 6 、 Figure 7 、Figure 8 and Figure 9 In some embodiments of the present invention, the adjusting screw 233 is a bidirectional screw. Specifically, the adjusting screw 233 has a first rod section and a second rod section, and the thread helix directions of the first rod section and the second rod section are opposite. The first wedge block 234 is threadedly connected to the first rod section. The adjusting device further includes a second pressing member 235 movably installed in the installation cavity 2310. The second pressing member 235 can pass through the side wall of the second handle 220 and abut against the first handle 210. That is, a through hole for the second pressing member 235 to pass through is provided on the side wall of the second handle 220. The second rod section of the adjusting screw 233 is threadedly connected to the second wedge block 236. The second wedge block 236 is located inside the installation cavity 2310. The second pressing member 235 is located between the second wedge block 236 and the first handle 210. A second inclined surface 2350 capable of cooperatively abutting against the second wedge block 236 is provided at one end of the second pressing member 235 away from the first handle 210. In this embodiment, the inclination direction of the second inclined surface 2350 is opposite to the inclination direction of the first inclined surface 2320, and the placement direction of the second wedge block 236 is opposite to the placement direction of the first wedge block 234. When the user turns the adjusting screw 233, the adjusting screw 233 can drive the first wedge block 234 and the second wedge block 236 to move relatively closer. The first wedge block 234 and the second wedge block 236 move closer to the first inclined surface 2320 and the second inclined surface 2350 correspondingly. Therefore, the first wedge block 234 and the second wedge block 236 drive the first pressing member 232 and the second pressing member 235 to move closer to the first handle 210 correspondingly, so that the first pressing member 232 and the second pressing member 235 pass through the side wall of the second handle 220 and press the first handle 210. When unlocking, the user only needs to turn the adjusting screw 233 in the reverse direction, and the first wedge block 234 and the second wedge block 236 move relatively away. At this time, the first wedge block 234 and the second wedge block 236 move away from the first inclined surface 2320 and the second inclined surface 2350 correspondingly. Therefore, the first pressing member 232 and the second pressing member 235 no longer tightly press the first handle 210, thereby realizing the unlocking between the first handle 210 and the second handle 220. By adopting the above structure, when the user turns the adjusting screw 233 of this embodiment, the adjusting screw 233 can drive the first wedge block 234 and the second wedge block 236 to simultaneously press the first pressing member 232 and the second pressing member 235. The first pressing member 232 and the second pressing member 235 cooperate to press the first handle 210 together. Therefore, the first pressing member 232 and the second pressing member 235 cooperate to lock the relative positions of the first handle 210 and the second handle 220 together, making the locking effect of the locking device 230 of this embodiment better.

[0041] It should be noted that in the above embodiments, the first wedge block 234 and the second wedge block 236 are correspondingly located outside the first pressing member 232 and the second pressing member 235. However, in some embodiments of the invention, the first wedge block 234 and the second wedge block 236 can be correspondingly arranged between the first pressing member 232 and the second pressing member 235. In this structure, when the user turns the adjusting screw 233, the adjusting screw 233 drives the first wedge block 234 and the second wedge block 236 to move relatively away from each other. During the process of the first wedge block 234 and the second wedge block 236 moving relatively away from each other, the first wedge block 234 contacts and abuts against the first inclined surface 2320 of the first pressing member 232, and the second wedge block 236 contacts and abuts against the second inclined surface 2350 of the second pressing member 235. Thus, the first wedge block 234 and the second wedge block 236 can correspondingly drive the first pressing member 232 and the second pressing member 235 to move closer to the first handle 210. The first pressing member 232 and the second pressing member 235 then pass through the side wall of the second handle 220 and squeeze the first handle 210, realizing the common cooperation of the first pressing member 232 and the second pressing member 235 to lock the relative positions of the first handle 210 and the second handle 220. When it is necessary to unlock the relative positions of the first handle 210 and the second handle 220, the user only needs to turn the adjusting screw 233 in the reverse direction. At this time, the first wedge block 234 and the second wedge block 236 move relatively closer along the adjusting screw 233. At this time, the first wedge block 234 moves away from the first inclined surface 2320 of the first pressing member 232, and the second wedge block 236 moves away from the second inclined surface 2350 of the second pressing member 235. The operation is simple and convenient.

[0042] In order to make the second handle 220 move more smoothly relative to the first handle 210 when the locking device 230 unlocks the relative positions between the first handle 210 and the second handle 220, in some embodiments of the present invention, a second elastic member 2351 is sleeved on the outer periphery of the second pressing member 235. Specifically, the second elastic member 2351 is a compression spring, or the second elastic member 2351 is an elastic silica gel sleeve or rubber sleeve. One end of the second elastic member 2351 abuts against the outer surface of the mounting seat 231 or the second handle 220, and the other end of the second elastic member 2351 abuts against the second pressing member 235. By adopting the above structure, when the user needs to turn the adjusting screw 233 in the reverse direction and make the second wedge block 236 remove the pressure applied to the second pressing member 235, the second elastic member 2351 can drive the second pressing member 235 to move away from the first handle 210, that is, the second pressing member 235 is separated from the outer surface of the first handle 210. Thus, the friction between the second pressing member 235 and the first handle 210 is eliminated. Therefore, the user can better drive the second handle 220 to move relative to the first handle 210, which is more labor-saving and makes the relative movement between the second handle 220 and the first handle 210 more smooth.

[0043] Refer to 5, Figure 6 , Figure 7 , Figure 8 and Figure 9 , in order to make the relative movement of the second handle 220 relative to the first handle 210 smoother, in some embodiments of the present invention, a guiding device for guiding the relative movement of the first handle 210 and the second handle 220 is provided on the other side of the second handle 220 away from the locking device 230. By adopting the above structure, after the user controls the locking device 230 to unlock the relative position locking between the first handle 210 and the second handle 220, when the user drives the second handle 220 relative to the first handle 210, the guiding device can guide the second handle 220 to reciprocate along the length direction of the first handle 210, thus making the relative movement between the second handle 220 and the first handle 210 smoother and more fluent.

[0044] In order to make the structure of the telescopic scissors in this embodiment more compact, in some embodiments of the present invention, the guiding device includes a guiding groove 310 and a guiding post 320. Specifically, the guiding groove 310 is a long strip-shaped groove, and the guiding groove 310 is opened on the outer surface of the first handle 210 along the length direction of the first handle 210, while the guiding post 320 is threadedly installed at a position corresponding to the guiding groove 310 on the side wall of the second handle 220, that is, a threaded hole is correspondingly opened on the side wall of the second handle 220 facing the guiding groove 310, and the guiding post 320 is threadedly installed in this threaded hole. When the user turns the guiding post 320 relative to the second handle 220, the guiding post 320 passes through the side wall of the second handle 220 and moves into the second handle 220, and the guiding post 320 is inserted into the guiding groove 310. It should be noted that the guiding post 320 does not tightly press the guiding groove 310, and only the end of the guiding post 320 is located in the guiding groove 310. At this time, the guiding post 320 and the guiding groove 310 are in a state of movable contact. When the user controls the locking device 230 to release the relative position locking between the first handle 210 and the second handle 220, and the user applies force to the second handle 220 and makes the second handle 220 move along the length direction of the first handle 210, the guiding post 320 can cooperate with the guiding groove 310 to guide the second handle 220 to reciprocate along the length direction of the first handle 210, thus making the relative movement between the second handle 220 and the first handle 210 smoother and more fluent. By adopting the above structure, not only can the guiding device better guide the second handle 220 to move relative to the first handle 210, but also the structure of the guiding device is simpler, and then the structure of the telescopic scissors in this embodiment is more compact, which is convenient for the production of telescopic scissors and helps to reduce the production cost of telescopic scissors.

[0045] In some embodiments of the present invention, the number of the guide posts 320 is two, and the two are arranged on the side wall of the second handle 220 at intervals along the length direction of the second handle 220, that is, two threaded holes corresponding to the guide grooves 310 are formed in the side wall of the second handle 220 at intervals, and the two guide posts 320 are respectively installed in the two threaded holes. When needed, the user can screw the two guide posts 320 into the inside of the second handle 220. The two guide posts 320 can pass through the side wall of the second handle 220 and be inserted into the guide grooves 310. At this time, the two guide posts 320 and the guide grooves 310 cooperate to guide together, so that the second handle 220 moves more smoothly relative to the first handle 210. Moreover, through the cooperation and positioning of the two guide posts 320 and the guide grooves 310, when the user holds the telescopic handle 200 to drive the scissor body 100 to cut, the first handle 210 and the second handle 220 are not easy to swing or shake relatively.

[0046] It should be noted that in the above embodiments, the guiding device adopts a structure in which two guide posts 320 and one guide groove 310 cooperate to guide together. In some embodiments of the present invention, the guiding device can also adopt other structures. For example, the guiding device includes two guide posts 320 and two guide grooves 310. The two guide grooves 310 are formed on the outer surface of the first handle 210 at intervals along the length direction of the first handle 210, and the two guide grooves 310 are parallel to each other. Two threaded holes corresponding to the two guide grooves 310 are formed in the side wall of the second handle 220 at intervals, and the two guide posts 320 are respectively installed in the two threaded holes. When needed, the user can screw the two guide posts 320 into the inside of the second handle 220. At this time, the two guide posts 320 can pass through the side wall of the second handle 220 and be inserted into the two guide grooves 310 respectively. At this time, one guide post 320 cooperates with one guide groove 310 to guide, and the other guide post 320 cooperates with the other guide groove 310 to guide. By adopting the above structure, the guiding device can better guide the second handle 220 to move relative to the first handle 210, and the first handle 210 and the second handle 220 are less likely to swing or shake relatively.

[0047] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
