Abstract
Description
Technical Field
[0001] This utility model relates to the field of gardening tools technology, and in particular to a retractable and adjustable gardening shears. Background Technology
[0002] In existing garden shears, some handles are designed to be telescopic and adjustable to accommodate different cutting needs. These telescopic handles typically use a threaded mechanism for adjustment and locking. For example, the two handle sections of the telescopic section are connected by a threaded connection, allowing the extension and retraction of the handle sections to change the length of the rotating arm. Alternatively, the two handle sections are movably fitted together, with a threaded bolt connecting the outer handle. Tightening the bolt locks the two handle sections together, while loosening the bolt releases this engagement, allowing the handle sections to move relative to each other for adjustment. Both of these structures are cumbersome when adjusting the length of the rotating arm, and the design needs improvement. Utility Model Content

[0031] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5A telescopic adjustable garden shears includes shear bodies 100, handles 200, and a telescopic adjustment structure. Two shear bodies 100 are rotatably connected to each other. Two handles 200 are provided, each corresponding to one of the two shear bodies 100. The shear bodies 100 and handles 200 are connected by the telescopic adjustment structure, which includes an adjustment groove 301, locking holes 302, and a locking element 310. The adjustment groove 301 is located on the shear body 100 and extends along the length of the handle 200. At least two locking holes 302 are provided and spaced apart along the extension direction of the adjustment groove 301. The locking element 310 is movably connected to the hand... The handle 200 is provided with an adjustment groove 301. The locking member 310 is provided with a locking part 311 that is adapted to the locking hole 302. The locking member 310 is provided with a pressing part 312 for pressing, so as to drive the locking member 310 to move relative to the handle 200, so that the locking member 310 has a locked state and an unlocked state relative to the handle 200. When the locking member 310 is in the locked state, the locking part 311 can be inserted into the locking hole 302 to restrict the movement of the locking member 310 along the adjustment groove 301. When the locking member 310 is in the unlocked state, the locking part 311 is disengaged from the locking hole 302, and the locking member 310 can move along the adjustment groove 301.
[0032] Understandably, such as Figure 1 and Figure 2 As shown, the front end of the shear body 100 is connected to the handle 200, and the rear end is the shearing engagement part. An adjusting groove 301 is located at the front end of the shear body 100 and extends along the front-to-back direction. A locking member 310 is movably connected to the handle 200 and can move up and down relative to the handle 200. The locking member 310 passes through the adjusting groove 301, and multiple locking holes 302 are spaced apart along the extending direction of the adjusting groove 301. (Refer to...) Figure 2 , Figure 4 and Figure 5When telescopic adjustment is required, the user can operate the pressing part 312. The pressing part 312 drives the locking part 310 to move downward relative to the handle part 200, so that the locking part 310 is in the unlocked state relative to the handle part 200. At this time, the locking part 311 disengages from the locking hole 302, and the locking part 310 can move along the adjustment groove 301, so that the handle part 200 can also move along the adjustment groove 301, adjusting the lever arm length of the rotating shear body 100. After the telescopic adjustment is completed, the locking part 310 moves to the position corresponding to the other locking hole 302, and the operation drives the pressing part 312 to reset upward, driving the locking part 310 to move upward, so that the locking part 310 is in the locked state relative to the handle part 200. At this time, the locking part 311 can be inserted into the locking hole 302 to restrict the movement of the locking part 310 along the adjustment groove 301, thereby restricting the movement of the handle part 200 relative to the shear body 100, and realizing the fixed position after adjustment. This utility model has a simple and reasonable structure. By operating the pressing part 312, the locking and unlocking states can be switched. The operation is simple and convenient, and it is easy to extend and adjust.
[0033] In practical applications, the specific structures of the shear body 100, handle 200, and locking element 310 can be set according to actual usage needs, and will not be described in detail here. They will be explained in detail below.
[0034] In some embodiments, the locking hole 302 partially overlaps with the adjusting groove 301, and the diameter of the locking hole 302 is larger than the width of the adjusting groove 301.
[0035] Understandably, such as Figure 2 , Figure 4 and Figure 5As shown, the locking part 311 has a stepped boss structure. The locking hole 302 partially overlaps with the adjusting groove 301, and the diameter of the locking hole 302 is larger than the width of the adjusting groove 301. In use, the locking member 310 moves downward to disengage the locking part 311 from the locking hole 302. After disengaging from the locking hole 302, the portion of the locking member 310 located in the adjusting groove 301 is adapted to the width of the adjusting groove 301, thus allowing it to move along the adjusting groove 301. However, when the locking part 311 is engaged in the locking hole 302, because the diameter of the locking hole 302 is larger than the width of the adjusting groove 301, and the locking part 311 is adapted to the locking hole 302, the locking part 311 cannot move along the adjusting groove 301, thereby achieving a locking effect. Its structure is simple and facilitates switching between locking and unlocking operations. In practical applications, in addition to the above structure, the locking hole 302 and the adjusting groove 301 can also be set separately. In this case, the locking part 311 is also separated from the locking member 310. Then, the locking part 311 is connected to the locking member 310 through a connecting structure, and is driven by the locking member 310 to move up and down together, so that the locking part 311 can be inserted into or released from the locking hole 302. Alternatively, the locking member 310 can also be connected to the handle member 200 by moving left and right. The locking hole 302 is connected to the side of the adjusting groove 301. When the locking member 310 moves left and right, the locking part 311 can be inserted into or released from the locking hole 302 to achieve locking and unlocking. The specific settings can be adjusted according to the actual needs of use.
[0036] In some embodiments, two locking holes 302 are provided and respectively located at both ends of the adjusting groove 301. It is understood that, as Figure 2 , Figure 4 and Figure 5 As shown, two locking holes 302 are respectively located at both ends of the adjusting groove 301, thereby realizing the telescopic adjustment of the boom length in two different states. In practical applications, three, four or more locking holes 302 can also be provided, thereby realizing multi-level telescopic adjustment of the boom length, which can be set according to actual usage needs.
[0037] In some embodiments, the handle 200 is provided with a slot 201, and the end of the scissor 100 is movably inserted into the slot 201. The extending direction of the slot 201 is consistent with the extending direction of the adjustment groove 301.
[0038] Understandably, such as Figure 2 , Figure 4 and Figure 5 As shown, the handle 200 has a slot 201 extending in the front-to-back direction. The rear end of the shear body 100 is movably inserted into the slot 201, thereby effectively covering the rear end of the shear body 100. The structure is simple and easy to use. In practical applications, the handle 200 and the shear body 100 can also be connected by other sliding fit structures, which can be set according to actual usage needs.
[0039] In some embodiments, the telescopic adjustment structure further includes a spring 320, which is sleeved on the locking member 310 and the two ends of the spring 320 act on the pressing part 312 and the handle member 200 respectively. The locking part 311 can be engaged in the locking hole 302 under the action of the spring 320.
[0040] Understandably, such as Figure 4 and Figure 5 As shown, the spring 320 is sleeved on the upper end of the locking member 310, and its two ends act on the pressing part 312 and the handle member 200, respectively. In use, pressing the pressing part 312 causes the locking member 310 to move downwards, simultaneously compressing the spring 320. After the extension / retraction adjustment is completed, the locking member 310 moves to the position corresponding to the locking hole 302. Releasing the pressure on the pressing part 312 allows it to return to its original position upwards under the action of the spring 320, causing the locking part 311 to engage in the locking hole 302. This simplifies operation, and the locking part 311 maintains a relatively stable locking effect under the action of the spring 320, making it convenient to use. In practical applications, in addition to the spring 320, the pressing part 312 can also be manually reset, depending on the specific needs of use.
[0041] In some embodiments, the handle member 200 is provided with a receiving recess 202, the spring member 320 is located in the receiving recess 202 and the pressing part 312 blocks the opening of the receiving recess 202.
[0042] Understandably, such as Figure 1 , Figure 4 and Figure 5 As shown, the receiving recess 202 has an upper opening structure. The locking member 310 passes through the receiving recess 202, and the spring member 320 is located in the receiving recess 202. The pressing part 312 covers the opening of the receiving recess 202, thereby covering the spring member 320, reducing exposed components, improving the appearance, and facilitating use. In actual applications, the specific structure of the handle member 200 can be changed according to the actual usage requirements.
[0043] In some embodiments, a rotation limiting locking structure is provided between the two shear bodies 100, which can restrict the relative rotation of the two shear bodies 100.
[0044] Understandably, by setting a rotation-limiting locking structure, when the shearing parts of the two shear bodies 100 rotate relative to each other to retract, the relative rotation of the two shear bodies 100 can be restricted by the rotation-limiting locking structure, thereby preventing the shearing parts from opening relative to each other. At this time, it is easier to operate the telescopic adjustment of the length of the power arm, and it is also easier to store the shears, reducing the possibility of blade injury and improving safety. In practical applications, the specific structure of the rotation-limiting locking structure can be set according to the actual use needs, and will not be described in detail here, but will be explained in detail below.
[0045] In some embodiments, the rotation limiting locking structure includes a rotation limiting member 110 and a rotation limiting slot 101. One of the two shear bodies 100 is rotatably connected to the rotation limiting member 110, and the other is provided with a corresponding rotation limiting slot 101. The rotation limiting member 110 can rotate and engage with the rotation limiting slot 101 to restrict the relative rotation of the two shear bodies 100.
[0046] Understandably, such as Figure 1 , Figure 2 and Figure 3 As shown, the rotation limiting component 110 is rotatably connected to one of the two shear bodies 100, and the other body is correspondingly provided with a rotation limiting slot 101. In use, refer to... Figure 3 The rotation limiting member 110 rotates and engages with the rotation limiting slot 101, thereby restricting the relative rotation of the two scissor bodies 100. To unlock, simply rotate the rotation limiting member 110 until it disengages from the rotation limiting slot 101. The structure is simple and easy to use. In practical applications, in addition to the above structure, the rotation limiting member 110 can also be inserted into the rotation limiting slot 101 by moving it to achieve rotation restriction; or, the rotation limiting member 110 can be fixed, and the limiting slot can be located on a movable member. The movable member drives the limiting slot to move, so that the rotation limiting member 110 and the rotation limiting slot 101 engage; or, the rotation limiting locking structure can be a sheath. When in use, the shearing engagement part at the rear end of the scissor body 100 is retracted into the sheath, thereby restricting the relative rotation and opening of the two scissor bodies 100. The specific design can be adjusted according to actual usage needs.
[0047] In some embodiments, one of the two shears 100 is provided with a notch 102 for accommodating plant branches, and the other is provided with a corresponding protruding blade 120 that can cooperate with the notch 102.
[0048] Understandably, such as Figure 1 , Figure 2 and Figure 3As shown, the notch 102 and the convex blade 120 are respectively located at the rear ends of the two shearing bodies 100. In use, the plant branch can be placed in the notch 102, and the handle 200 is operated to rotate the two shearing bodies 100 relative to each other and close. The convex blade 120, in conjunction with the notch 102, is used to trim the plant branch, which helps prevent the plant branch from slipping relative to the shearing bodies 100 and facilitates the trimming of harder or thicker plant branches. In practical applications, the specific structure of the notch 102 and the convex blade 120 can be set according to actual usage needs.
[0049] In some embodiments, an elastic auxiliary member 130 is provided between the two shear bodies 100. The two ends of the elastic auxiliary member 130 act on the two shear bodies 100 respectively to assist the convex blade 120 and the notch 102 in rotating relative to each other and opening.
[0050] Understandably, such as Figure 1 , Figure 2 and Figure 3 As shown, the two ends of the elastic auxiliary member 130 act on the front ends of the two shear bodies 100 respectively. Under the elastic force of the elastic auxiliary member 130, the two shear bodies 100 tend to rotate and open relative to each other, thereby assisting the convex blade 120 and the concave opening 102 to rotate and open relative to each other, making it convenient for the user to operate with one hand. In practical applications, the elastic auxiliary member 130 can be a spring or other elastic structure, which can be set according to the actual needs of use.
[0051] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
