[0002] Currently, for the picking of crops such as prickly ash, strawberries, citrus fruits, wolfberries, apples, and roses for thorn removal, traditionally manual handpicking or using electric cutting tools for picking is adopted. There are also manual picking tools on the market, but the current picking tools cannot be adjusted according to the size of the user's palm, and cannot adapt to picking people with different palm sizes, restricting the range of users, with low flexibility and comfort in use. Summary of the Utility Model
[0003] The embodiment of the utility model provides a multi-gear adjustable handheld crop picker to solve the technical problem that the picking tool cannot be applicable to picking people with different palm sizes.
[0004] The embodiment of the utility model provides a multi-gear adjustable handheld crop picker, including a handheld picker and a detachable handle. A jack is opened on the lower end surface of the tail of the handheld picker, and a plug matched with the jack is arranged at the top of the detachable handle. The detachable handle is detachably connected with the handheld picker by inserting the plug into the jack.
[0005] Its working principle and process are as follows:
[0006] When using the handheld picker, according to the use requirements and comfort, the plug of the detachable handle can be inserted into the jack or the detachable handle can be removed, so that the distance between the handheld end and the switch of the handheld picker is more suitable for the size of the user's palm, with a larger range of users, higher comfort in use, and the flexibility of the handheld picker can be freely changed to meet the use requirements of the user.
[0007] Preferably, at least two rows of jacks are opened along the length direction of the handheld picker, and the detachable handle is connected with the handheld picker by inserting the plug into different rows of jacks.
[0008] According to the size of the user's palm, the plug at the top of the detachable handle can be inserted into different rows of jacks to achieve different gears, so that the distance between the detachable handle and the switch of the handheld picker is more suitable for the size of the user's palm.
[0009] Preferably, there are three rows of jacks, and the intervals between the three rows of jacks are the same. Each row of jacks has at least two. Two rows of plugs are arranged at the top of the detachable handle. Each row of plugs has at least two and corresponds to the positions of the jacks respectively.
[0010] The arrangement of three rows of jacks divides the position gears of the detachable handle into three gears. The distances between the three rows of jacks are equal, which facilitates the cooperation of the two rows of plugs with the jacks at any plugging position. When cooperating with the third row of jacks, the first row of plugs on the detachable handle is connected to the third row of jacks, while the second row of plugs is in a vacant state or abuts against the tail end of the handheld picker. The arrangement of the two rows of plugs makes the connection of the detachable handle more stable and prevents the phenomenon of falling off or loosening.
[0011] Preferably, the handheld picker includes a shearing mechanism, a trigger mechanism, a spring, and a strip-shaped housing. One end of the housing is a shearing end, and the other end is a handheld end. The jacks are arranged on the lower surface of the handheld end. The shearing mechanism is strip-shaped. An exit blade opening for the shearing mechanism to extend out is formed at the shearing end of the housing. A sliding hole for the movement of the trigger mechanism is formed in the lower part of the housing. The trigger mechanism is slidably connected to the sliding hole. The trigger mechanism is connected to the shearing mechanism. The tail end of the shearing mechanism is connected to the spring, and the spring is arranged inside the handheld end of the housing.
[0012] The sliding hole facilitates the trigger mechanism to linearly displace along the sliding hole, so that the trigger mechanism drives the shearing mechanism to operate. The shearing mechanism forms a shearing gap outside the exit blade opening to shear various crop branches. After the trigger mechanism drives the shearing mechanism to move, the elastic force of the spring can make the shearing mechanism automatically return to its original position.
[0013] Preferably, the shearing mechanism includes a movable knife bar and a fixed knife bar. The length of the movable knife bar is greater than that of the fixed knife bar. One end of the movable knife bar is provided with a movable shearing knife, and the other end of the movable knife bar is formed with an insertion rod. The insertion rod is inserted into the spring. An installation hole is formed in the insertion rod. A hook that is vertically arranged in the spring and is snapped into the installation hole is provided corresponding to the installation hole. The width of the movable shearing knife is the same as the width of the exit blade opening. The width of the movable knife bar is greater than the width of the exit blade opening and the diameter of the spring. A plurality of fixing holes are arranged at equal intervals along the length direction of the movable knife bar corresponding to the position of the trigger mechanism. The top of the trigger mechanism is connected to the fixing holes. One end of the fixed knife bar is provided with a fixed shearing knife. Both the fixed shearing knife and the movable shearing knife pass through the exit blade opening and are arranged outside the housing. A long hole is formed at the end of the fixed knife bar far from the fixed shearing knife. The trigger mechanism is slidably arranged in the long hole. The distance between the two farthest fixing holes is less than or equal to the length of the long hole. The fixed knife bar is fixedly arranged in the housing. A guiding waist hole is formed in the movable knife bar. A fixing screw that sequentially passes through the fixed knife bar and the guiding waist hole from bottom to top is arranged inside the housing. The length of the guiding waist hole is the same as the length of the long hole.
[0014] The trigger mechanism passes through the fixing holes on the movable knife bar and can drive the movable knife bar to move. The long hole restricts the moving distance and direction of the trigger mechanism and the movable knife bar. By selecting different fixing holes through which the trigger mechanism passes, the moving range of the movable knife bar can be adjusted, which is beneficial to setting different shearing clearances for different crops. The guiding waist hole on the movable knife bar plays an auxiliary guiding role in the movement of the movable knife bar through the fixing screws.
[0015] Preferably, the movable shearing knife is in a "C" shape, the inner side of the movable shearing knife is the blade, the end edge of the fixed shearing knife is the blade and is crescent-shaped. The movement of the movable shearing knife forms a closed bite with the fixed shearing knife. The distance between the blades of the movable shearing knife and the fixed shearing knife is equal to the moving distance of the trigger mechanism in the long hole. An inwardly concave bayonet is provided on one side of the fixed shearing knife in the same direction as the blade of the movable shearing knife. The inwardly concave bayonet is in a V-shaped structure. The length of the side of the inwardly concave bayonet away from the bayonet is greater than the length of one side of the bayonet. The side of the fixed shearing knife opposite to the inwardly concave bayonet is the cutting blade.
[0016] The body of the movable knife bar is located inside the housing, and the knife head end passes through the cutting opening and can move freely. The width of the body of the movable knife bar is greater than the width of the cutting opening, so it plays a role in restricting its displacement. The "C" shape of the movable shearing knife can hook the crop branches to the fixed shearing knife, so as to cooperate with the fixed shearing knife to cut the branches. The crescent-shaped fixed shearing knife can prevent the branches from sliding compared with the flat-mouth shearing knife and limit them within the shearing range. At the same time, the movable shearing knife can play a role in cutting agricultural products and can be used as a cutting sickle. The inwardly concave bayonet can be used as a bottle opener. The longer side of the inwardly concave bayonet serves as a fulcrum, and the shorter side serves as a bottle opener. Or the branches can be placed in the V-shaped groove of the inwardly concave bayonet and twisted off. The cutting blade of the fixed shearing knife can cut items such as rose thorns.
[0017] Preferably, at both ends corresponding to the cutting opening between the knife head end and the body of the fixed knife bar, limiting bayonets are provided. The width of the limiting bayonets is the same as the inner wall thickness of the cutting opening. The width between the two limiting bayonets is the same as the width of the cutting opening. The width of the body of the fixed knife bar is the same as the width of the body of the movable knife bar. The tail end of the fixed knife bar is in a T shape.
[0018] The limiting bayonets of the fixed knife bar cooperate with the cutting opening to play an auxiliary fixing role for the fixed knife bar. When the fixed knife bar is stressed, the cutting opening will also play a supporting role for the fixed knife bar.
[0019] Preferably, the trigger mechanism includes a toggle trigger, a sliding block, and a connecting shaft. The sliding block is arranged at the upper end of the toggle trigger, the connecting shaft is arranged at the center of the upper end face of the sliding block. The toggle trigger is slidably connected to the sliding hole, the sliding block is slidably connected to the long hole, and the connecting shaft is inserted into the fixing hole and the diameter of the connecting shaft matches the diameter of the fixing hole.
[0020] The toggle trigger is slidably connected to the sliding hole, and the sliding block is slidably connected to the long hole. The double cooperation makes the displacement distance and direction of the trigger mechanism more stable. The connection of the connecting shaft to the fixing hole of the movable knife bar is beneficial for the trigger mechanism to drive the movable knife bar to move.
[0021] Preferably, a protective cover is sleeved outside the movable shearing knife and the fixed shearing knife, and the internal clearance distance of the protective cover is the same as the sum of the thicknesses of the movable shearing knife and the fixed shearing knife.
[0022] The setting of the protective cover plays a protective role for the movable shearing knife and the fixed shearing knife of the shearing mechanism, preventing the shearing mechanism of the handheld picker from being damaged. At the same time, when accidentally touching the trigger mechanism of the handheld picker, it can limit the movement of the shearing mechanism and prevent accidental injury to the operator.
[0023] In summary, the beneficial effects of the present utility model are as follows:
[0024] When using the handheld picker, according to the palm size of the user, the plug at the top of the detachable handle can be inserted into different rows of jacks to achieve different gears, which can make the distance between the detachable handle and the switch of the handheld picker more suitable for the palm size of the user, with a wider range of users, higher comfort, and freely changing the flexibility of the handheld picker.

A jack 13 is provided on the lower end surface of the tail of the handheld picker, and a plug 21 matching the jack 13 is provided at the top of the detachable handle 2. The detachable handle 2 is detachably inserted into the jack 13 through the plug 21 to be connected to the handheld picker.
[0039] Its working principle and process are as follows:
[0040] When using the handheld picker, according to the usage requirements and comfort, the plug 21 of the detachable handle 2 can be inserted into the jack 13 or the detachable handle 2 can be removed, which can make the distance between the handheld end and the switch of the handheld picker more suitable for the palm size of the user, the range of the user group is larger, the comfort is higher, and the flexibility of the handheld picker can be freely changed.
[0041] In another embodiment of the present utility model, as Figure 5As shown in the figure, two rows of jacks 13 are provided along the length direction of the handheld picker. The detachable handle 2 is connected to the handheld picker by inserting the plug 21 into different rows of jacks 13.
[0042] According to the size of the user's palm, the plug 21 at the top of the detachable handle 2 can be inserted into different rows of jacks 13 to achieve different gears, which can make the distance between the detachable handle 2 and the switch of the handheld picker more suitable for the size of the user's palm.
[0043] In another embodiment of the present invention, as Figure 5 shown, three rows of jacks 13 are provided, and the intervals between the three rows of jacks 13 are the same. Each row of jacks 13 has two. Two rows of plugs 21 are provided at the top of the detachable handle 2. Each row of plugs 21 has two and corresponds to the positions of the jacks 13 respectively. The setting of the three rows of jacks 13 divides the position gears of the detachable handle 2 into three gears. The intervals between the three rows of jacks 13 are equal, which facilitates the cooperation of the two rows of plugs 21 with the jacks 13 at any insertion position. When cooperating with the third row of jacks 13, the first row of plugs 21 on the detachable handle 2 is connected to the third row of jacks 13, while the second row of plugs 21 is in a vacant state or abuts against the tail end of the handheld picker. The setting of the two rows of plugs 21 makes the connection of the detachable handle 2 more stable and prevents the phenomenon of falling off and loosening. The lower surface of the tail end of the handheld picker is arc-shaped, and the top surface of the detachable handle 2 is also arc-shaped and fits with the tail end of the handheld picker. The heights of the two rows of plugs 21 are different, and the jacks 13 are distributed on the arc surface of the tail end of the handheld picker.
[0044] In another embodiment of the present invention, as Figures 4-9 shown, the handheld picker includes a shearing mechanism 4, a trigger mechanism 3, a spring 5 and a strip-shaped housing 1. One end of the housing 1 is a shearing end, and the other end is a handheld end. The jack 13 is provided on the lower surface of the handheld end. The shearing mechanism 4 is strip-shaped. An exit blade opening 11 for the shearing mechanism 4 to extend out is provided at the shearing end of the housing 1. A sliding hole 12 for the movement of the trigger mechanism 3 is provided in the lower part of the housing 1. The trigger mechanism 3 is slidably connected to the sliding hole 12. The trigger mechanism 3 is connected to the shearing mechanism 4. The tail end of the shearing mechanism 4 is connected to the spring 5. The spring 5 is arranged inside the handheld end of the housing 1.
[0045] The sliding hole 12 is conducive to pulling the trigger mechanism 3 to linearly displace along the sliding hole 12, so that the trigger mechanism 3 drives the shearing mechanism 4 to operate. The shearing mechanism 4 forms a shearing gap outside the exit blade opening 11 to shear various crop branches. After the trigger mechanism 3 drives the shearing mechanism 4 to move, the elastic force of the spring 5 can make the shearing mechanism 4 automatically return to its original position.
[0046] In another embodiment of the present invention, as Figures 4-9As shown in the figure, the shearing mechanism 4 includes a movable knife bar 41 and a fixed knife bar 42. The length of the movable knife bar 41 is greater than that of the fixed knife bar 42. One end of the movable knife bar 41 is provided with a movable shearing knife 411, and the other end of the movable knife bar 41 is formed with an insertion rod 414. The insertion rod 414 is inserted into the spring 5. An installation hole 415 is formed on the insertion rod 414. A hook that snaps into the installation hole 415 is vertically provided in the spring 5 at a position corresponding to the installation hole 415. The width of the movable shearing knife 411 is the same as the width of the outlet 11. The width of the movable knife bar 41 is greater than the width of the outlet 11 and the diameter of the spring 5. At positions corresponding to the trigger mechanism 3 along the length direction of the movable knife bar 41, a number of fixing holes 413 are provided at equal intervals. The top of the trigger mechanism 3 is connected to the fixing holes 413. One end of the fixed knife bar 42 is provided with a fixed shearing knife 421. Both the fixed shearing knife 421 and the movable shearing knife 411 pass through the outlet 11 and are arranged outside the housing 1. A long hole 424 is formed at one end of the fixed knife bar 42 away from the fixed shearing knife 421. The trigger mechanism 3 is slidably arranged in the long hole 424. The distance between the two farthest fixing holes 413 is less than or equal to the length of the long hole 424. The fixed knife bar 42 is fixedly arranged in the housing 1. A guiding waist-shaped hole 412 is formed on the movable knife bar 41. A fixing screw that sequentially passes through the fixed knife bar 42 and the guiding waist-shaped hole 412 is provided in the housing 1.

[0047] The trigger mechanism 3 passes through the fixing holes 413 on the movable knife bar 41 and can drive the movable knife bar 41 to move. The long hole 424 restricts the moving distance and moving direction of the trigger mechanism 3 and the movable knife bar 41. By selecting different fixing holes 413 through which the trigger mechanism 3 passes, the moving range of the movable knife bar 41 can be adjusted, which is beneficial to setting different shearing clearances for different crops. The guiding waist-shaped hole 412 on the movable knife bar 41 plays an auxiliary guiding role in the movement of the movable knife bar 41 through the fixing screw.
[0048] In another embodiment of the present invention, as Figure 8 and Figure 9 shown, the movable shearing knife 411 is in a "C" shape. The inner side of the movable shearing knife 411 is the blade. The end edge of the fixed shearing knife 421 is the blade and is in a crescent shape. The movement of the movable shearing knife 411 forms a closed bite with the fixed shearing knife 421. The distance between the blades of the movable shearing knife 411 and the fixed shearing knife 421 is equal to the distance that the trigger mechanism 3 moves in the long hole 424. An inwardly concave bayonet 422 is formed on one side of the fixed shearing knife 421 in the same direction as the blade direction of the movable shearing knife 411. The inwardly concave bayonet 422 is in a V-shaped structure. The length of the side of the inwardly concave bayonet 422 away from the bayonet is greater than the length of one side of the bayonet. The side of the fixed shearing knife 421 opposite to the inwardly concave bayonet 422 is the cutting blade 425.
[0049] The body of the movable knife bar 41 is located inside the housing 1, and the knife head end can move freely through the cutting opening 11. The width of the body of the movable knife bar 41 is greater than the width of the cutting opening 11, so it plays a role in restricting its displacement. The "C" - shaped structure of the movable shearing knife 411 can hook the crop branches to the fixed shearing knife 421, so as to cooperate with the fixed shearing knife 421 to cut off the branches. The crescent - shaped fixed shearing knife 421 can prevent the branches from sliding compared with the flat - mouth shearing knife, restricting them within the shearing range. At the same time, the movable shearing knife 411 can play a role in cutting agricultural products and can be used as a cutting sickle. The concave - type bayonet 422 can be used as a bottle opener. The longer side of the concave - type bayonet 422 serves as a fulcrum, and the shorter side serves as a bottle - opener. Also, the branches can be placed in the V - shaped groove of the concave - type bayonet 422 and broken off. The cutting edge 425 of the fixed shearing knife 421 can cut items such as rose thorns.
[0050] In another embodiment of the present utility model, as Figure 8 and Figure 9 shown, at both ends corresponding to the cutting opening 11 between the knife head end and the body of the fixed knife bar 42, limiting bayonets 423 are provided. The width of the limiting bayonet 423 is the same as the inner wall thickness of the cutting opening 11, the width between the two limiting bayonets 423 is the same as the width of the cutting opening 11, the width of the body of the fixed knife bar 42 is the same as the width of the body of the movable knife bar 41, and the tail end of the fixed knife bar 42 is in a T - shape for facilitating the fixation of the fixed knife bar 42.
[0051] The limiting buckle of the fixed knife bar 42 cooperates with the cutting opening 11 to play an auxiliary fixing role for the fixed knife bar 42. When the fixed knife bar 42 is stressed, the cutting opening 11 will also play a supporting role for the fixed knife bar 42.
[0052] In another embodiment of the present utility model, as Figures 1-3 and Figure 7 shown, the trigger mechanism 3 includes a toggle trigger 31, a sliding block 32 and a connecting shaft 33. The sliding block 32 is arranged at the upper end of the toggle trigger 31, and the connecting shaft 33 is arranged at the central position of the upper end surface of the sliding block 32. The toggle trigger 31 is slidably connected with the sliding hole 12, the sliding block 32 is slidably connected with the long hole 424, and the connecting shaft 33 is inserted into the fixing hole 413 and the diameter of the connecting shaft 33 matches the diameter of the fixing hole 413. The lower end of the toggle trigger 31 is arc - shaped, which is suitable for the ergonomic principle of the human finger.
[0053] The toggle trigger 31 is slidably connected with the sliding hole 12, and the sliding block 32 is slidably connected with the long hole 424. With the double cooperation, the displacement distance and direction of the trigger mechanism 3 are more stable. The connecting shaft 33 is connected with the fixing hole 413 of the movable knife bar 41, which is beneficial for the trigger mechanism 3 to drive the movable knife bar 41 to move.
[0054] In another embodiment of the present utility model, as Figures 1-3 shown, a protective cover 6 is sleeved outside the movable shearing blade 411 and the fixed shearing blade 421. The internal clearance distance of the protective cover 6 is the same as the sum of the thicknesses of the movable shearing blade 411 and the fixed shearing blade 421. The protective cover 6 has a cuboid structure with rounded corners at both ends.
[0055] The setting of the protective cover 6 plays a protective role for the movable shearing blade 411 and the fixed shearing blade 421 of the shearing mechanism 4, preventing the shearing mechanism 4 of the handheld picker from being damaged. At the same time, when accidentally touching the trigger mechanism 3 of the handheld picker, it can limit the movement of the shearing mechanism 4 and prevent accidental injury to the operator.
