Description

Technical Field

[0001] The utility model relates to the field of electric tools, in particular to electric scissors with adjustable cutting angles. Background Art

[0002] Electric shears are tools used for pruning branches in orchards, gardens, vines, etc. With the advancement of technology, many electric products have become more and more user-friendly and convenient in terms of function, structure, and usage, but there are still many defects in the use process.

[0003] Prior art CN116584262A discloses a control method for electric scissors with shear compensation. The utility model sets a compensation adjustment mode. When the blade closure is affected, the compensation stroke is adjusted so that the movable blade can have a suitable compensation stroke after closing to ensure the blade closure. However, compensation can only be performed within the overlap stroke range, and a complex program is required to calculate the compensation stroke, and the electronic control cost is too high.

[0004] Prior art CN116210469A discloses a garden electric scissors and a method of using the same. The utility model can control the rotation angle of the fixed blade relative to the moving blade by setting a limit assembly and an angle adjustment assembly, solving the problem that the fixed scissors on the market are currently fixed and cannot be adjusted, and is convenient for effectively working when the thickness is greater than the angle between the moving scissors and the fixed scissors. However, the above scheme requires the use of an angle adjustment assembly to adjust the angle of the fixed scissors assembly, and the additional angle adjustment assembly adopts a more complex structure. In addition, the fixed scissors assembly needs to withstand a large shearing force when shearing, which also puts forward higher requirements on the reliability of the angle adjustment assembly.

[0005] Therefore, in order to compensate for the impact of blade wear in the prior art, the program compensation adopted will cause excessively high electrical control costs, while the adjustment of the angle of the fixed scissor assembly increases the complexity of operation and also increases the maintenance cost. Utility Model Content

[0019] In the above-mentioned electric scissors with adjustable cutting angle, the side wall of the adjustment slide is provided with multiple serrated grooves, and the adjustment member includes a pressing arm and a serrated rib provided on the pressing arm. The serrated rib cooperates with the serrated groove to fix the adjustment member, and the pressing arm drives the serrated rib to disengage from the serrated groove to unlock the adjustment member.

[0020] Compared with the prior art, the advantages of the utility model are:

[0021] By movably installing the final position sensor on the main body, and the final position sensor can adjust the position relative to the main body, the current problem of reduced closing degree caused by blade wear is solved. The final position sensor is used to control the drive component so that the movable blade can stop at the specified final position to complete the shearing with the fixed blade. When the movable blade is worn, the wear of the movable blade is compensated by adjusting the position of the final position sensor, and the movable blade can still complete the shearing action with the fixed blade. Moreover, the device only needs to adjust the position of the final position sensor, and does not need to modify the electronic control program, nor does it need to modify the existing movable blade and fixed blade. The shear compensation of the worn movable blade is achieved at a lower cost and with less structure. Compared with the existing movable blade wear compensation scheme, the operation difficulty is greatly reduced. Only the relative position of the final position sensor on the main body needs to be adjusted to change the final position of the movable blade, and the adjustment is simpler and faster.

[0022] Furthermore, the main body is provided with an adjusting member for adjusting the position of the final position sensor, the adjusting member is movably mounted on the main body, and the final position sensor is fixed to the adjusting member.

[0023] Furthermore, the moving blade is provided with a triggering member for triggering the sensor, and the trajectory of the final position sensor driven by the adjusting member overlaps with the trajectory of the moving blade followed by the triggering member. The final position sensor can be triggered by the triggering member, so that the final position sensor can sense the position of the moving blade. The movement trajectory of the final position sensor driven by the adjusting member overlaps with the movement trajectory of the triggering member, which makes it convenient to adjust the final position sensor without considering whether the position corresponds to the triggering member, that is, the final position sensor can be stopped at any position by the adjusting member, and the triggering member can trigger the final position sensor when the moving blade moves.

[0025] Furthermore, the side wall of the adjustment slot is provided with a plurality of positioning holes, and the adjustment member includes a positioning pin and a pressing arm. The positioning pin is inserted into the positioning hole to fix the adjustment member, and the positioning pin has a tendency to remain in the positioning hole. The pressing arm is exposed to the outside of the main body, and the pressing arm drives the positioning pin to disengage from the positioning hole, so that the adjustment member can move along the adjustment slot. The separation of the positioning pin and the positioning hole is controlled by the pressing arm, so that the positioning pin can be quickly adjusted to match the positioning hole at that position. After the positioning pin and the positioning hole are matched, the two are not easy to separate, and the relative position of the final position sensor can be fixed more firmly.

[0026] Furthermore, the positioning pin is located on the side of the pressing arm facing the positioning hole, the pressing arm is an elastic arm, and the positioning pin has a tendency to be kept in the positioning hole by the elasticity of the pressing arm; or, the positioning pin is located on the side of the pressing arm facing the positioning hole, an elastic member is connected to the pressing arm, and the positioning pin has a tendency to be kept in the positioning hole by the elastic force of the elastic member. The two different ways of providing the positioning pin with a tendency to be kept in the positioning hole both use elastic force to keep the positioning pin in the positioning hole, which has high reliability.

The operation is simple, which reduces the learning difficulty for customers.

[0027] Furthermore, the adjusting member further comprises a bracket, the bracket clamps the pressing arm and the positioning pin, the end of the bracket passes through the adjusting slot, and the final position sensor is fixed to the end of the bracket. The bracket can better fix the final position sensor, and the end of the bracket extends out of the adjusting slot, so that the final position sensor fixed to the end of the bracket can be closer to the moving blade, thereby obtaining a more accurate position signal of the moving blade.

[0028] Furthermore, the outer end of the pressing arm is provided with a pressing portion exposed from the main body, and the pressing portion passes through the bracket. The pressing portion exposed from the main body is provided to make it more convenient for the user to operate the pressing arm so as to adjust the position of the final position sensor, and the pressing portion passes through the bracket to avoid the bracket hindering the movement of the pressing portion.

[0029] Furthermore, the adjusting member includes a slider and a limit screw, the slider is installed in the adjusting slot, the final position sensor is fixed on the slider, the limit screw extends from the outside to the inside into the adjusting slot and connects with the slider, tightening the limit screw locks the slider in the adjusting slot, and loosening the limit screw allows the slider to move along the adjusting slot.

[0046] An electric scissors with adjustable cutting angles comprises a main body 100, the main body 100 is provided with a fixed blade 200 and a movable blade 300 for shearing, a driving assembly 400 for driving the movable blade 300 to move, and a sensor for controlling the rotation angle of the movable blade 300; the movable blade 300 has an initial position opened relative to the fixed blade 200 and a final position closed with the fixed blade 200, the driving assembly 400 drives the movable blade 300 to move between the initial position and the final position to perform a shearing action, and the sensor comprises a final position sensor 500 for detecting that the movable blade 300 reaches the final position; the final position sensor 500 is movably mounted on the main body 100, and can adjust its position relative to the main body 100 to change the final position to which the movable blade 300 can move, thereby adjusting the degree of closure between the movable blade 300 and the fixed blade 200.

[0047] By movably installing the final position sensor 500 on the main body 100, and the final position sensor 500 can be adjusted relative to the main body 100, the problem of the current blade wear causing the closing degree to decrease is solved. The final position sensor 500 is used to control the driving assembly 400, so that the movable blade 300 can stop at the specified final position and complete the shearing with the fixed blade 200. When the movable blade 300 is worn, the position of the final position sensor 500 is adjusted to compensate for the wear of the movable blade 300, and the movable blade 300 can still complete the shearing action with the fixed blade 200. Moreover, the device only needs to adjust the position of the final position sensor 500, and there is no need to modify the electric control program, and there is no need to modify the existing movable blade 300 and the fixed blade 200. The shearing compensation of the worn movable blade 300 is achieved at a lower cost and with less structure. Compared with the existing movable blade 300 wear compensation scheme, the operation difficulty is greatly reduced. Only the relative position of the final position sensor 500 on the main body 100 is adjusted to change the final position of the movable blade 300, and the adjustment is simpler and faster.

[0052] Embodiment 1:

[0053] See also Figures 1 to 6This is the first embodiment of the utility model of an electric scissors with adjustable cutting angle. The electric scissors include a main body 100. The main body 100 is provided with a fixed blade 200 and a movable blade 300 for shearing, a driving component 400 for driving the movable blade 300 to move, and a sensor for controlling the rotation angle of the blade. The fixed blade 200 and the movable blade 300 are generally arranged on the top of the main body 100, and a rechargeable battery is provided at the bottom of the main body 100. The driving component 400 includes a driving motor, a driving gear and an electronic control component. The electronic control component is used to control the operating state of the driving motor. The rechargeable battery is used to power the driving motor. The driving motor is meshed with the movable blade 300 through the driving gear, thereby driving the movable blade 300 to swing within a certain range to achieve shearing cooperation with the fixed blade 200.

[0054] The movable blade 300 has an initial position of opening relative to the fixed blade 200 and a final position of closing with the fixed blade 200. The initial position generally refers to the maximum position of the movable blade 300 relative to the fixed blade 200. The initial position is not affected by the wear of the movable blade 300, so the initial position of the movable blade 300 is generally fixed. The final position is the position where the movable blade 300 and the fixed blade 200 are closed to complete the shearing. If the movable blade 300 is worn, the movable blade 300 and the fixed blade 200 will not be able to complete the shearing, that is, the branch cannot be completely cut off, and there may be a situation where the bark is still connected. Therefore, when the movable blade 300 is worn, it is necessary to adjust the final position so that the movable blade 300 can be completely closed with the fixed blade 200.

[0055] In this embodiment, a sensor is used to sense the swing position of the moving blade 300, and the sensor sends a signal to the electric control component to determine whether the moving blade 300 swings to the initial position or the final position. An initial position sensor is provided on the main body 100 corresponding to the initial position of the moving blade 300, and a final position sensor 500 is provided corresponding to the final position of the moving blade 300. Since the moving blade 300 needs to be adjusted to the final position due to wear, the final position sensor 500 is movably installed on the main body 100, and can adjust its position relative to the main body 100, thereby changing the final position of the moving blade 300 and adjusting the closing degree of the moving blade 300 and the fixed blade 200. Since only the position of the final position sensor 500 is adjusted in this embodiment, the entire electric control program does not need to be changed. When the final position sensor 500 senses that the moving blade 300 rotates to this position, it still sends a signal to stop the driving motor from running. Moreover, since only the position of the final position sensor 500 is adjusted, there is no need to set a complex adjustment mechanism, which is conducive to simplifying the structure of the electric scissors and reducing the overall failure rate.

[0056] Specifically, the main body 100 is provided with an adjusting member 600 for adjusting the position of the final position sensor 500, the adjusting member 600 is movably mounted on the main body 100, and the final position sensor 500 is fixed on the adjusting member 600. By changing the relative position of the adjusting member 600 and the main body 100, the position of the final position sensor 500 can be adjusted. In addition to using the adjusting member 600, a bonding area can also be defined on the main body 100, and the final position sensor 500 can be attached to the bonding area by bonding, which can also achieve the adjustment of the position of the final position sensor 500.

[0057] Furthermore, the moving blade 300 is provided with a triggering member 310 for triggering the touch sensor, and the trajectory of the final position sensor 500 driven by the adjusting member 600 overlaps with the trajectory of the moving blade 300 following the movement of the triggering member 310. By cooperating with the final position sensor 500, the final position sensor 500 can more accurately grasp the actual position of the moving blade 300, reduce the probability of false triggering, and improve the accuracy of the shearing between the moving blade 300 and the fixed blade 200. In addition, in this embodiment, the trajectory of the movement of the final position sensor 500 overlaps with the trajectory of the movement of the triggering member 310 following the moving blade 300, and no deviation will occur when the final position sensor 500 adjusts its position, thereby avoiding the situation where the final position sensor 500 deviates and cannot accurately sense the position of the triggering member 310. In addition to using the final position sensor 500 that cooperates with the triggering member 310, other final position sensors 500 that can sense the position of the moving blade 300 without the practical triggering member 310 can also be used. Of course, the movement trajectory of the final position sensor 500 still needs to overlap with the movement trajectory of the moving blade 300.

[0058] On the basis of the above embodiment, the main body 100 is provided with an adjustment groove 110 for limiting the movement trajectory of the adjustment member 600. The adjustment member 600 slides along the adjustment groove 110. The adjustment trajectory of the adjustment member 600 is limited by the adjustment groove 110. This allows the user to adjust the position of the final position sensor 500 more conveniently without worrying that the final position sensor 500 moves out of the prescribed trajectory, causing the final position sensor 500 to fail to function. In addition, through the adjustment groove 110, the user can clearly know in which direction the adjustment member 600 needs to be moved, and the moving distance is easier to grasp, so the position of the final position sensor 500 can be adjusted more accurately.

[0059] Furthermore, a plurality of positioning holes 111 are provided on the side wall of the adjustment slide 110, and the adjustment member 600 includes a positioning pin 610 and a pressing arm 620. The positioning pin 610 is inserted into the positioning hole 111 to fix the adjustment member 600. Through the cooperation between the positioning hole 111 and the positioning pin 610, the relative fixed position relationship between the adjustment member 600 and the main body 100 can be ensured after adjustment. Even if the electric scissors vibrate during use, the relative position of the final position sensor 500 on the main body 100 can still be maintained unchanged. The positioning pin 610 has a tendency to remain in the positioning hole 111, and when not subject to external force, the positioning pin 610 will always be located in the corresponding positioning hole 111. The end of the pressing arm 620 is exposed to the outside of the main body 100, and the pressing arm 620 drives the positioning pin 610 to disengage from the positioning hole 111, that is, the pressing arm 620 mainly plays a role in moving the adjusting member 600. By exposing the pressing arm 620 to the outside of the main body 100, the user can operate the pressing arm 620 conveniently. When the pressing arm 620 is acted upon by an external force, the positioning pin 610 will be driven to disengage from the positioning hole 111, and the user can move the adjusting member 600. When it is moved to a suitable position, the pressing arm 620 is released to allow the positioning pin 610 to enter the corresponding positioning hole 111.

[0060] How the positioning pin 610 is maintained in the positioning hole 111 includes but is not limited to the following structural forms:

[0061] One is as Figure 4 , Figure 5 As shown, the positioning pin 610 is located on the side of the pressing arm 620 facing the positioning hole 111. The pressing arm 620 is an elastic arm, that is, the pressing arm 620 can be made of elastic material, such as elastic plastic. In this embodiment, the pressing arm 620 has two parts, an upper part and an lower part, and a gap is left between the two parts of the pressing arm 620. The gap is the elastic deformation space left when the pressing arm 620 is pressed, and it can also allow the positioning pin 610 to leave a distance from the positioning hole 111. The positioning pin 610 also obtains a tendency to be kept in the positioning hole 111 through the elasticity of the pressing arm 620.

[0062] The other is that the positioning pin 610 is located on the side of the pressing arm 620 facing the positioning hole 111, and the pressing arm 620 is connected with an elastic member, such as a spring or a spring sheet, and the elastic force provided by the spring or the spring sheet allows the positioning pin 610 to have a tendency to remain in the positioning hole 111. When the positioning pin 610 needs to be disengaged from the positioning hole 111, the pressing arm 620 needs to be pressed so that the pressing arm 620 overcomes the elastic force of the elastic member; when the adjustment is completed, the elastic force of the elastic member allows the pressing arm 620 to return to its initial position, and the positioning pin 610 is located in the positioning hole 111.

[0063] Furthermore, in order to better fix the final position sensor 500 on the adjusting member 600, the adjusting member 600 also includes a bracket 630, which clamps the pressing arm 620 and the positioning pin 610, thereby maintaining the relative position of the bracket 630, the pressing arm 620 and the positioning pin 610. The end of the bracket 630 passes through the adjusting slot 110, and the final position sensor 500 is fixed to the end of the bracket 630. The above structure enables the bracket 630 to maintain synchronous sliding with the pressing arm 620 and the positioning pin 610 in the adjusting slot 110, and the part of the bracket 630 extending out of the adjusting slot 110 provides an installation platform for the final position sensor 500. Since the bracket 630 extends out of the adjusting slot 110, there is more space at the end of the bracket 630, and the final position sensor 500 can be stably fixed on the bracket 630. At the same time, the final position sensor 500 can also be closer to the moving blade 300 to obtain more accurate moving position information of the moving blade 300.

[0064] In order to facilitate the user to operate the pressing arm 620 to adjust the position of the final position sensor 500, the outer end of the pressing arm 620 is provided with a pressing part 621 located in the main body 100, and the pressing part 621 also passes through the bracket 630, that is, the pressing part 621 will be completely exposed to facilitate better operation by the user, and the area of ​​the pressing part 621 can be enlarged to obtain a larger contact surface with the user's fingers, thereby avoiding discomfort when the user operates the pressing part 621.

[0065] When the movable blade 300 and the fixed blade 200 cannot be completely closed due to wear of the movable blade 300, the user can press the pressing arm 620, and the pressing arm 620 will drive the positioning pin 610 to disengage from the positioning hole 111. At this time, the adjusting member 600 can be slid along the adjusting slide 110, and the adjusting member 600 will drive the final position sensor 500 to move together. After the final position sensor 500 is moved to a suitable position, the pressing arm 620 is released, and the positioning pin 610 enters the corresponding positioning hole 111 due to the elastic deformation of the pressing arm 620 itself or the elastic deformation of the elastic member, and the fixing of the complete adjusting member 600 and the main body 100 is completed. When the movable blade 300 swings toward the fixed blade 200, the movable blade 300 can trigger the final position sensor 500 at the new swinging position, and the driving assembly 400 controls the movable blade 300 to stop running, and the closing of the movable blade 300 and the fixed blade 200 is completed. This embodiment changes the position of the final position sensor 500 and uses the driving component 400 to control the swing amplitude of the moving blade 300, thereby offsetting the error caused by the wear of the moving blade 300. There is no need to adjust the original electric scissors control program, nor to add complex control components to the electric scissors. Shear compensation for the worn moving blade 300 is achieved at a lower cost and with fewer structures. Compared with the existing wear compensation scheme for the moving blade 300, the operating difficulty is greatly reduced. It is only necessary to adjust the relative position of the final position sensor 500 on the main body 100 to change the final position of the moving blade 300, and the adjustment is simpler and faster.

[0066] Embodiment 2:

[0067] like Figure 7 As shown, the difference between this embodiment and the first embodiment is that the positioning pin 610 and the positioning hole 111 are not used to fix the relative position of the adjusting member 600 and the main body 100. In this embodiment, a plurality of sawtooth grooves are provided on the side wall of the adjusting slide 110, and a sawtooth convex rib is provided on the pressing arm 620. The relative position of the adjusting member 600 and the main body 100 is fixed by the cooperation of the sawtooth convex rib and the sawtooth groove. The adjustment method of the adjusting member 600 is the same as that of the first embodiment. By using the position adjustment method of the adjusting member 600 and the main body 100 of this embodiment, a plurality of sawtooth convex ribs and a plurality of sawtooth grooves can be provided to cooperate with each other at the same time, thereby greatly increasing the stability of the adjusting member 600 and the main body 100 when they are fixedly connected.

[0069] Embodiment three:

[0070] like Figure 8As shown, the difference between this embodiment and the first embodiment is that the structure of the adjusting member 600 is different. The adjusting member 600 includes a slider 640 and a stop screw 650. The slider 640 is installed in the adjusting slot 110. The stop screw 650 extends from one side of the adjusting slot 110 and is threadedly connected with the slider 640. After one end of the slider 640 extends from the other side of the adjusting slot 110, the final position sensor 500 is fixed to the slider 640 extending from the adjusting slot 110. By screwing the stop screw 650, the slider 640 is squeezed with the side wall of the adjusting slot 110, and the friction between the slider 640 and the side wall of the adjusting slot 110 is increased, so that the relative position of the slider 640 and the adjusting slot 110 is fixed. When the position of the final position sensor 500 needs to be adjusted, just loosen the stop screw 650 to reduce the pressure between the slider 640 and the adjusting slot 110, move the slider 640 to the appropriate position of the adjusting slot 110, and then tighten the stop screw 650. The structure of the adjusting member 600 of this embodiment can realize stepless adjustment, that is, the slider 640 can be moved to any position of the adjusting slot 110 , thereby realizing more precise position adjustment of the final position sensor 500 .
