[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Embodiment 1, as Figure 1-2 As shown, a shearing performance tester for lithium-ion pruning shears comprises four supporting legs 1, the upper ends of the four supporting legs 1 are commonly fixedly connected with a working mechanism 2, a fixing mechanism 3 is provided on the left side of the working mechanism 2, a testing mechanism 4 is provided on the right side of the working mechanism 2, a control center 5 is provided at the front right side of the working mechanism 2, a motor 2 6 is provided at the lower right side of the working mechanism 2, a gear disc 2 7 is fixedly connected to the output end of the motor 2 6, and the outer surface of the gear disc 2 7 is meshedly connected with the lower side of the testing mechanism 4.

[0032] It should be noted that the specific installation method of the control center 5 and the motor 2 6, the circuit connection method and the control method in the present invention are all conventional designs and are conventional design means of designers. The control center 5 is composed of components such as a controller, a display, a power supply, a switch, etc., and the motor 2 6 is controlled by the control center 5.

[0033] First, prepare the lithium-ion pruning shears to be tested, and then fix different types of lithium-ion pruning shears through the fixing mechanism 3 according to actual test requirements. After fixation, the fixing mechanism 3 transports them in the direction of the testing mechanism 4, and when the lithium-ion pruning shears are transported to the right by the fixing mechanism 3, the testing mechanism 4 is adjusted with the cooperation of the working mechanism 2, and then the fixing mechanism 3 controls the lithium-ion pruning shears to shear the testing mechanism 4. In addition, by starting the motor 2 6 and driving the testing mechanism 4 to rotate and adjust through the gear disc 2 7, the actual cutting diameters of different types of lithium-ion pruning shears can be tested. At the same time, the specific situation of the shearing surface is fed back to the control center 5 by the testing mechanism 4, and the cutting effect can be intuitively and clearly seen through the control center 5.

[0034] In order to achieve the auxiliary fixing mechanism 3 and the testing mechanism 4 to complete the shearing performance test of the lithium-electric pruning shears, as Figure 3 As shown, the working mechanism 2 includes a workbench 21, a round hole 22 is opened on the right side of the middle upper end of the workbench 21, a sliding groove 28 is opened in the middle of the upper end of the workbench 21, a motor 27 is fixedly connected to the left side of the lower end of the workbench 21, two supports 25 are fixedly connected to the left side of the lower end of the workbench 21, a threaded rod 24 is connected to the inner cavities of the two supports 25 for common rotation, a transmission wheel 26 is fixedly connected to the left end of the threaded rod 24 and the output end of the motor 27, the two transmission wheels 26 are connected by belts, a lifting group 23 is fixedly connected to the middle part of the lower end of the workbench 21, the right side of the lower end of the workbench 21 is fixedly connected to the upper end of the motor 26, and the upper ends of the four supporting legs 1 are fixedly connected to the lower end of the workbench 21.

[0035] It should be noted that the specific installation method of the motor 27, the circuit connection method and the control method in the present invention are all conventional designs, which are conventional design means of designers, and the motor 27 is controlled by the control center 5.

[0036] First, the fixing mechanism 3 is installed through the sliding groove 28 and the threaded rod 24, and the testing mechanism 4 is installed through the workbench 21 and the circular hole 22. Then, the lithium-ion pruning shears to be tested are installed in the fixing mechanism 3. Then, the control center 5 controls the motor 27 to rotate. With the cooperation of the two transmission wheels 26 and the belt, the threaded rod 24 is rotated in the inner cavity of the two supports 25. The rotation of the threaded rod 24 drives the fixing mechanism 3 to slide to the right in the inner cavity of the sliding groove 28. When the fixing mechanism 3 moves to the right, the lifting group 23 is compressed, so that the lifting group 23 adjusts the testing mechanism 4 upward. At this time, the fixing mechanism 3 controls the lithium-ion pruning shears to shear the testing mechanism 4, so as to achieve the purpose of assisting the fixing mechanism 3 and the testing mechanism 4 to complete the shearing performance test of the lithium-ion pruning shears. In addition, after the cutting is completed, the threaded rod 24 drives the fixing mechanism 3 to slide to the left in the inner cavity of the sliding groove 28, and the testing mechanism 4 and the lifting group 23 return to their initial state.

[0037] Further explanation, such as Figure 4 and Figure 5 As shown, the lifting group 23 includes a shell 231, the upper end of the shell 231 is fixedly connected to the middle of the lower end of the workbench 21, a toothed disc 233 is rotatably connected to the middle of the inner cavity of the shell 231, a rack 232 is slidably connected to the right side of the inner cavity of the lifting group 23, an L-shaped pull rod 234 is fixedly connected to the lower end of the rack 232, a toothed plate 236 is slidably connected to the left side of the inner cavity of the shell 231, the left side of the rack 232 and the right side of the toothed plate 236 are meshed with the toothed disc 233, a rotating rod 235 is rotatably connected to the lower side of the inner cavity of the toothed plate 236, an elastic sheet 238 is fixedly connected to the upper side of the inner cavity of the toothed plate 236, a traction rope 237 is fixedly connected to the upper side of the inner cavity of the toothed plate 236, and the traction rope 237 is located directly below the elastic sheet 238, and the left end of the traction rope 237 is fixedly connected to the upper side of the rotating rod 235.

[0038] In detail, when the threaded rod 24 drives the fixing mechanism 3 to move to the right in the inner cavity of the sliding groove 28, the lower side of the fixing mechanism 3 presses down the rotating rod 235, and the rotating rod 235 rotates toward the toothed plate 236, so that the toothed plate 236 moves vertically downward, thereby driving the toothed plate 233 to rotate. Through the rotation of the toothed plate 233, the rack 232 drives the L-shaped pull rod 234 to move vertically upward, thereby driving the test mechanism 4 to move upward. When the rotating rod 235 rotates to the inner cavity of the toothed plate 236 to compress the elastic sheet 2 38, the fixing mechanism 3 moves to the rightmost side in the inner cavity of the sliding slot 28 and stops moving. At this time, the fixing mechanism 3 controls the lithium-powered pruning shears to shear the testing mechanism 4 to complete the testing work. After the shearing is completed, the fixing mechanism 3 moves to the left, and under the elastic force of the elastic sheet 238, the rotating rod 235 pops out of the inner cavity of the tooth plate 236 and rotates to the left to restore the initial state. By installing the traction rope 237, the rotating rod 235 is pulled so that when the fixing mechanism 3 moves to the right, it can be compressed to the rotating rod 235.

[0039] Embodiment 2: Based on Embodiment 1, this embodiment achieves the purpose of fixing different types of lithium-ion pruning shears, such as Figure 6 As shown, the fixing mechanism 3 includes a threaded slider 32, a groove 33 is provided on the lower side of the right end of the threaded slider 32, a convex slider 31 is fixedly connected to the upper end of the threaded slider 32, a pad 34 is fixedly connected to the middle of the bottom wall of the inner cavity of the convex slider 31, a screw component 36 is rotatably connected to the inner cavity of the pad 34 and the middle of the inner cavity of the convex slider 31, the left and right sides of the outer surface of the screw component 36 are meshedly connected to the slide seats 35, the upper sides of the two slide seats 35 are rotatably connected to the clamping plate 38, the upper side of the middle part of the front end of the convex slider 31 is rotatably connected to the knob component 37, the upper side of the rear end of the convex slider 31 is fixedly connected to the stretching group 39, the front side of the outer surface of the screw component 36 is connected to the knob component 37 by a belt, and the lower side of the outer surface of the convex slider 31 is slidably connected to the inner cavity of the sliding groove 28.

[0040] It should be noted that the screw component 36 is composed of a screw and a pulley, the knob component 37 is composed of a knob and a pulley, and the pulley in the screw component 36 is connected to the pulley in the knob component 37 by a belt, and the pad 34 is composed of a rectangular block and a slide rail. First, the lithium-ion pruning shears to be tested are placed on the inner cavity of the convex slide 31 and the pad 34, and then the knob component 37 is rotated with the cooperation of the belt to drive the screw component 36 to rotate, and the rotation of the screw component 36 drives the two slides 35 to move away from or close to each other on the slide rails in the pad 34, until the two slides 35 respectively drive the clamping plates 38 thereon to the pieces to be tested. The different types of lithium-ion pruning shears to be tested are fixed, and then, the transmission wheel 26 is driven by the motor 27. With the cooperation of the belt, the threaded slider 32 slides on the outer surface of the threaded rod 24 and drives the convex slide plate 31 to move to the right in the inner cavity of the sliding groove 28. During the movement, the inner cavity of the groove 33 will be stuck on the upper side of the rotating rod 235 and compress the rotating rod 235. With the cooperation of the toothed disc 233, the rack 232 and the L-shaped pull rod 234, the test mechanism 4 is moved upward. Finally, the lithium-ion pruning shears are started by the stretching group 39 to shear the test mechanism 4, thereby achieving the purpose of fixing different types of lithium-ion pruning shears.

[0041] Further explanation, such as Figure 7 As shown, the stretching group 39 includes two supports 391, the inner cavities of the two supports 391 are rotatably connected to a threaded rod 392, the right side of the outer surface of the threaded rod 392 is meshedly connected to a rotating seat 393, the middle part of the upper end of the rotating seat 393 is rotatably connected to an electric telescopic rod 394, the front side of the outer surface of the electric telescopic rod 394 is fixedly connected to a pressure plate 395, and the front ends of the two supports 391 are fixedly connected to the upper side of the rear end of the convex slide plate 31.

[0042] It should be noted that the specific installation method, circuit connection method and control method of the electric telescopic rod 394 and the pressure plate 395 in the present invention are all conventional designs, which are conventional design means of designers. The pressure plate 395 is composed of a buckle plate and a pressure sensor, and the pressure sensors in the electric telescopic rod 394 and the pressure plate 395 are both controlled by the control center 5.

[0043] In detail, after the two clamps 38 fix the lithium-ion pruning shears, the threaded rod 392 is then rotated to make the rotating seat 393 move left and right on the outer surface of the threaded rod 392. The switch buttons on the different types of lithium-ion pruning shears are adjusted to the appropriate position. When the lithium-ion pruning shears are needed to shear the test mechanism 4, the electric telescopic rod 394 is contracted to drive the pressure plate 395 to press the switch button on the lithium-ion pruning shears, and the lithium-ion pruning shears are started to shear the test mechanism 4. At the same time, the pressure plate 395 will record the pressure felt and feed it back to the control center 5. In addition, the vibration generated by the lithium-ion pruning shears shearing the test mechanism 4 will also be fed back to the control center 5.

[0044] Embodiment 3: Based on Embodiment 1 and Embodiment 2, this embodiment cooperates with the fixing mechanism 3 to complete the purpose of shearing test of the lithium-powered pruning shears. Figure 8 and Fig. 9 As shown, the testing mechanism 4 includes a rotating sleeve 41, the inner cavity of the rotating sleeve 41 is rotatably connected to a turntable 43, a plurality of through holes 44 are provided in a circular array at the upper end of the turntable 43, and cutting columns 45 are provided in the inner cavities of the plurality of through holes 44. A rotating group 42 is provided on the lower side of the plurality of cutting columns 45 and the lower end of the rotating sleeve 41, a shooting component 46 is fixedly connected in the middle of the rotating group 42, and the upper end of the rotating sleeve 41 is fixedly connected to the middle of the lower end of the workbench 21.

[0045] It should be noted that the specific installation method of the shooting component 46, the circuit connection method and the control method in the present invention are all conventional designs, which are conventional design means of designers. The shooting component 46 is composed of a telescopic rod and a small camera, and is controlled by the control center 5. In addition, a plurality of through holes 44 correspond one-to-one to a plurality of cutting columns 45, and a plurality of cutting columns 45 are made of branches with different diameters.

[0046] When the control center 5 controls the motor 26 to drive the gear disk 27 to rotate and adjust the rotating group 42, with the cooperation of the plurality of cutting columns 45, the turntable 43 will be driven to rotate in the inner cavity of the rotating sleeve 41, and the cutting columns 45 of different diameters will be rotated to the appropriate position according to the actual shearing requirements, and the L-shaped pull rod 234 will be driven to move upward by the rack 232, thereby driving the rotating group 42 and one of the cutting columns 45 to move upward to the appropriate position, and the cutting column 45 is sheared by the lithium-ion pruning shears. After the shearing is completed, the shooting component 46 takes a picture of the shearing plane on the cutting column 45 and feeds it back to the control center 5 to observe the shearing flatness, and the operation is repeated until the actual maximum shearing diameter of the lithium-ion pruning shears is detected, and finally the shearing test of different types of lithium-ion pruning shears is realized, and the upper layer of waste after shearing can be discharged through the inner cavity of the turntable 43.

[0047] Further explanation, such as Fig.10As shown, the rotating group 42 includes a connecting frame 421, a pulley ring 423 is fixedly connected to the upper horizontal end of the connecting frame 421, a rotating gear ring 422 is rotatably connected to the outer surface of the pulley ring 423, a plurality of positioning columns 424 are arranged in a circular array on the upper end of the rotating gear ring 422, the outer surfaces of the plurality of positioning columns 424 are slidably connected to mounting seats 425, the outer surfaces of the plurality of mounting seats 425 are fixedly connected to slots 426, the upper ends of the plurality of mounting seats 425 are provided with circular grooves 427, the inner cavities of the plurality of circular grooves 427 are respectively slidably connected to the lower sides of the outer surfaces of the plurality of cutting columns 45, and the lower end of the shooting component 46 is fixedly connected to the middle part of the upper horizontal end of the connecting frame 421.

[0048] In detail, the circular grooves 427 provided on the plurality of mounting seats 425 correspond to the plurality of cutting columns 45 one by one, and each mounting seat 425 is connected to each other by sliding upward and downward movement, and the rotating rod 235 drives the tooth plate 236 to slide downward, so that the tooth plate 233 rotates, and then drives the rack 232 and the L-shaped pull rod 234, so that the L-shaped pull rod 234 drives the adjacent slot 426 to move upward, and through the coordinated use of the slot 426 and the mounting seat 425, the cutting column in the circular groove 427 is driven. The cutting column 45 moves upward in the inner cavity of the through hole 44, and the cutting column 45 is sheared by the lithium-powered pruning shears. After the shearing is completed, the threaded slider 32 drives the convex slide plate 31 to move to the left in the inner cavity of the sliding groove 28, and the groove 33 no longer compresses the rotating rod 235. Under the gravity of the mounting seat 425, the cutting column 45, the rack 232, and the L-shaped pull rod 234, the toothed plate 233 rotates in the opposite direction, so that the toothed plate 236 drives the rotating rod 235 to move upward to restore the initial state, and the mounting seat 425 and the cutting column 45 also return to the initial state, and then the toothed disc 27 is driven by the starting motor 26 to rotate the rotating gear ring 422 to a suitable position on the outer surface of the pulley ring 423, so that the new cutting column 45 is rotated to the position of the cutting column 45 after being cut, and is ready to move upward for cutting until the maximum cutting diameter of the lithium-electric pruning shears is detected. The design of driving the cutting column 45 to slide up and down by the mounting seat 425 will not cause other cutting columns 45 to affect the shearing test of the lithium-electric pruning shears. In addition, the vibration generated when the lithium-electric pruning shears shear the cutting columns 45 of different diameters will be fed back to the control center 5 by the pressure plate 395, and the pressure generated by pressing the switch button of the lithium-electric pruning shears by the pressure plate 395 is used in conjunction with the control center 5, and the control center 5 displays the pressure sensing time of the pressure plate 395, which displays the shearing time of the lithium-electric pruning shears on the cutting column 45, and measures the shearing performance of the lithium-electric pruning shears together with the flatness of the plane of the sheared cutting column 45.
