[0029] The clamping part 7 is movably connected to one side of the seat body 1, is used for mounting and cooling massage with the arm of the person, and is elastically pressed against the arm of the person, so as to improve the stability and support of the person holding the grip 2. The clamping part 7 comprises a cross frame 17, which mainly serves as a fixing support. The two side plates 18 are fixedly connected to the two side ends of the cross frame 17, are located on the same side of the cross frame 17, and are fixed at the positions of the pressing sleeves 25. The pressing sleeves 25 are fixedly connected to the outer surfaces of the side plates 18, are elastically pressed against the arm of the person, realize elastic support of the tea picking machine, and realize double-point support in cooperation with the grip 2, so as to avoid that the person fixes the grip 2 with one hand for a long time and increase the difficulty of holding.

[0030] The clamping part 7 further comprises the mounting shafts 12, which are fixedly connected to the two sides of the seat body 1, are fixed in position, and mainly serve as supports. The outer surfaces of the mounting shafts 12 are movably connected with the torsional spring seats 13. The outer surfaces of the torsional spring seats 13 are movably connected with the rotating sleeves 14. The torsional spring seats 13 have torsional force and exert counter-rotating force on the rotating sleeves 14. When the rotating sleeves 14 rotate, the torsional spring seats 13 synchronously rotate, the torsional force of the torsional spring seats 13 increases, and the counter-rotating force of the rotating sleeves 14 increases.

[0031] The moving rods 16 are movably connected inside the rotating sleeves 14. The moving rods 16 can move up and down inside the rotating sleeves 14 and adjust the height of the cross frame 17, so as to adjust the elastic pressing position of the pressing sleeves 25 against the person. One end of each moving rod 16 is fixedly connected with the side wall of the rotating sleeve 14 through the elastic member 15, and the other end is fixedly connected with the side wall of the cross frame 17, so as to drive the cross frame 17 to move and rotate. The elastic member 15 has elasticity and can be a spring or the like. The elastic member 15 is arranged to facilitate elastic return of the moving rod 16, so as to adjust the elastic pressing force of the moving rod 16.

[0032] The clamping part 7 further comprises: an air outlet hole 20 formed in the inner side plate 18, for discharging gas; the gas in the inner side plate 18 can be discharged to the inner part of the pressing sleeve 25 along the air outlet hole 20; an abutting hole 22 formed in the inner support plate 21 and matched with the air outlet hole 20, for adjusting the overlapping area with the air outlet hole 20; when the abutting hole 22 moves to the end of the horizontal frame 17, the overlapping area of the air outlet hole 20 and the abutting hole 22 decreases, and the amount of gas in the air outlet hole 20 entering the inner part of the pressing sleeve 25 along the abutting hole 22 decreases; a cooling fan 19 fixedly connected to one side of the side plate 18 and having an output end communicated with the air outlet hole 20, for introducing gas into the inner part of the air outlet hole 20; the cooling fan 19 continuously works and introduces gas into the inner part of the air outlet hole 20, thereby avoiding the problem that the pressing sleeve 25 is pressed by the arm of the person for a long time and sweating and discomfort.

[0033] The clamping part 7 further comprises: a telescopic part 23 having one end fixedly connected to the side wall of the horizontal frame 17 and the other output end fixedly connected to the side wall of the inner support plate 21, for adjusting the moving distance of the inner support plate 21; the telescopic part 23 is started and the output end is elongated, the output end of the telescopic part 23 drives the inner support plate 21 to move away from the end of the horizontal frame 17, the telescopic part 23 can be an electric telescopic rod structure; a partition layer 26 having side walls fixedly connected to the side wall of the pressing sleeve 25 or the side plate 18 and corresponding to the inner support plate 21, for dividing the inner part of the pressing sleeve 25 into multiple spaces and making each space not communicated; the main function of the partition layer 26 is to divide the inner space of the pressing sleeve 25, thereby facilitating the adjustment of the amount of gas in the inner part of the pressing sleeve 25 according to different tea picking postures, and corresponding adjustment of the pressing force of the pressing sleeve 25 on the arm of the person, improving the stability and sealing performance of subsequent tea picking.

[0034] An exhaust hole 27 formed in the inner part of the pressing sleeve 25, for discharging the gas in the inner part of the pressing sleeve 25; the gas in the inner part of the pressing sleeve 25 is continuously discharged along the exhaust hole 27; an anti-skid pad 28 fixedly connected to the outer surface of the pressing sleeve 25 and distributed in a staggered manner with the exhaust hole 27, for limiting the friction with the arm of the person; the end of the anti-skid pad 28 is frictionally fixed to the outer surface of the arm of the person, further improving the stability of the tea picking machine.

[0035] The end of the pressing sleeve 25 is fixedly connected with the side plate 18 and the side wall of the cross frame 17, so that the inside of the pressing sleeve 25 is a closed space, and the gas can only be continuously discharged along the discharge hole 27, the outer surface of the inner support plate 21 is in elastic sealing contact with the inner wall of the pressing sleeve 25, and the elastic deformation amount of the pressing sleeve 25 is adjusted when the inner support plate 21 moves, the pressing sleeve 25 has elasticity, the anti-skid pads 28 also have elasticity, the end of the plurality of anti-skid pads 28 has a large friction coefficient and has good anti-skid performance, the anti-skid pads 28 are elastically rubbed against the arm to limit the pressing sleeve 25 from being separated from the arm, the partition layer 26 is made of the same material as the pressing sleeve 25 and is uniformly distributed, the pressure sensor 24 is used to detect the pressure value at the end thereof and adjust the movement amount of the subsequent inner support plate 21 according to the pressure value.

[0036] When a person holds the tea picking machine to pick tea, the person needs to hold the tea picking machine at different angles due to the different heights of tea trees, thereby reducing the stability and accuracy of the person holding the tea picking machine; and the tea picking machine continuously works and generates vibration, which is continuously transmitted to the person and causes vibration damage to the person's tiger mouth; and in the prior art, the clamping stability of the tea picking machine is improved by means of the clamping part 7, but due to the different friction forces of different people's arms, the pressing force required when the clamping part 7 supports the tea picking machine is different, thereby easily causing the clamping part 7 to slip with the person's arm and reducing the limiting balance effect; as the tea picking machine works for a long time, the person's arm is prone to ache, and the clamping part 7 and the arm are prone to sweating due to long-term extrusion and support, thereby reducing the comfort of picking tea; and when the person is hit or accidentally separates from holding the handle 2, the seat body 1 drives the collecting hopper 29 at the other end and the like to rotate in the opposite direction and fall downward, not only the collecting hopper 29 will fall downward and hit the tea tree, but also the cross frame 17 and the like will collide with the person's palm and cause damage.

[0037] In order to solve the above problems, when the handheld tea picking machine is actually used, one hand of the person drives the rotating sleeve 14 to twist the torsional spring seat 13 and rotate, and the other hand passes through the position between the cross frame 17 and the seat body 1 and holds the handle 2, after the rotating sleeve 14 is loosened, the rotating sleeve 14 is driven to rotate in the opposite direction under the action of the torsional force of the torsional spring seat 13, the rotating sleeve 14 synchronously drives the moving rod 16 to rotate in the opposite direction, the moving rod 16 drives the cross frame 17 at the end to rotate in the opposite direction, the cross frame 17 drives the pressing sleeve 25 to rotate in the opposite direction and completes elastic pressing with the person's arm, and the plurality of anti-skid pads 28 are elastically extruded with the person's arm and provide friction.

[0038] In this process, due to the different smoothness of the person's arm, if the person wears sunscreen sleeves and the like to reduce the friction coefficient, the moving rod 16 is driven to move towards the end of the rotating sleeve 14 under the action of the elastic force of the elastic member 15, the moving rod 16 synchronously drives the pressing sleeve 25 to move through the cross frame 17, and the friction between the plurality of anti-skid pads 28 at the end of the pressing sleeve 25 and the arm does not meet the requirements and there is a risk of slipping.

[0039] At this time, the control box 3 controls the cooling fan 19 to start and introduce gas through the air outlet 20. The gas enters the pressing sleeve 25 through the docking hole 22. The gas inside the pressing sleeve 25 is discharged through the discharge hole 27. Some of the gas causes the pressing sleeve 25 to continuously undergo elastic deformation, which, together with the anti-slip pad 28 and the person's arm, applies pressing pressure. At the same time, the telescopic part 23 starts and the output end extends. The output end of the telescopic part 23 drives the inner support plate 21 to move away from the crossbeam 17. The end of the inner support plate 21 synchronously drives the pressing sleeve 25 to move. The pressing sleeve 25 drives multiple The pressing pressure between the anti-slip pad 28 and the person's arm increases, and the overlapping area of ​​the docking hole 22 and the air outlet 20 increases. When the cooling fan 19 is working, the amount of gas generated enters the inside of the pressing sleeve 25 along the air outlet 20 and the docking hole 22, which increases the pressing pressure applied to the person's arm by the anti-slip pad 28. The pressure value detected by the pressure sensor 24 continues to increase, further improving the friction between the anti-slip pad 28 and the arm, preventing the anti-slip pad 28 at the end of the pressing sleeve 25 from slipping on the person's arm and reducing the friction limiting effect.

[0040] Subsequently, when the elastic element 15 can no longer move the moving rod 16, that is, when the friction between the anti-slip pad 28 at the end of the pressing sleeve 25 and the person's arm reaches a suitable value, the position of the pressing sleeve 25 will not change. The person presses the operation button 5 and starts the tea picking machine. The pressure value detected by the pressure sensor 24 is the preset pressure value, and the movement of the subsequent inner support plate 21 is adjusted according to the preset pressure value to further satisfy the friction limit pressing effect of the pressing sleeve 25 on different arm friction forces, making it more adaptable and more stable.

[0041] Then, the motor 601 starts and drives the drive gear 602 to rotate. The rotation of the drive gear 602 drives the driven gear 603 to rotate. The driven gear 603 drives the eccentric wheel 604 to rotate eccentrically and drives the reciprocating frame 10 to move back and forth inside the base frame 8 through the hinge rod 605. The reciprocating frame 10 drives the cutting tooth 11 to move back and forth continuously and cooperates with the fixed tooth 9 to cut and pick the tea leaves. The fallen tea leaves enter the collection hopper 29 to wait for recycling.

[0042] Furthermore, the cooling fan 19 is activated and gas is introduced into the air outlet 20. The gas continuously enters the pressing sleeve 25 along the docking hole 22, and the gas inside the pressing sleeve 25 is continuously discharged along the discharge hole 27, thereby realizing the air cooling process of the person's arm and avoiding the pressing sleeve 25 and anti-slip pad 28 from being pressed against the arm for a long time and causing discomfort symptoms such as high temperature and sweating.

[0043] Meanwhile, the driving part 6 works continuously to drive the seat body 1 to vibrate, and the seat body 1 transmits the vibration to the rotating sleeve 14 and the moving rod 16 in turn, and then transmits the vibration to the pressing sleeve 25 through the cross frame 17, and the pressing sleeve 25 continuously presses the arm through the anti-skid pad 28, and the elastic shock absorption of the pressing sleeve 25 and the anti-skid pad 28 and the arm can avoid the vibration damage to the personnel's tiger mouth or arm caused by the long-time vibration of the tea picking machine, and effectively improve the comfort and stability of use.

[0044] In addition, the vibration force not only realizes the pulse pressing of the pressing sleeve 25 and the anti-skid pad 28 on the arm and improves the blood circulation effect, avoids the problem of muscle spasm caused by the long-time hand-held tea picking machine, but also realizes the pulse change of the gas amount discharged along the discharge hole 27, further realizes the pulse adjustment change of the gas amount discharged from the discharge hole 27, effectively improves the pressing and cooling effect of the pulse gas discharged from the discharge hole 27 on the personnel's arm, ensures the personnel to stably operate the tea picking machine for a long time, and the pressure value change range detected by the pressure sensor 24 in the above process is within the set range, so the control box 3 does not control the stretching part 23 to work, and the position of the inner supporting plate 21 does not change.

[0045] When the personnel continuously operate and pick different height tea trees, the included angle between the personnel and the seat body 1 changes continuously, for example, when the height of the tea tree decreases, the personnel needs to move the seat body 1 downward, at this time, since the height of the personnel is certain, the included angle between the personnel and the seat body 1 increases, the arm and the pressing sleeve 25 extrude each other and drive the pressing sleeve 25 to rotate, the pressing sleeve 25 drives the moving rod 16 and the rotating sleeve 14 to rotate synchronously through the cross frame 17, and the rotating sleeve 14 twists the torsional spring seat 13 to rotate synchronously, but in the process, since the included angle between the cross frame 17 and the pressing sleeve 25 and the moving rod 16 is certain, the pressing force applied by the personnel's arm to the different positions of the pressing sleeve 25 is different.

[0046] And according to the above process, the arm of the person and the pressing force of the pressing sleeve 25 located below increase, the pressure value detected by the pressure sensor 24 increases and is greater than the above-mentioned pressure preset value, at this time, in order to avoid the deformation of the pressing sleeve 25 being too large and causing the pressing loss to the arm of the person, the control box 3 controls the telescopic part 23 located below to start and the output end to shorten, the output end of the telescopic part 23 drives the inner support plate 21 to move close to the end of the horizontal frame 17, the pressing force applied by the end of the inner support plate 21 to the inner wall of the pressing sleeve 25 decreases, the pressure value detected by the pressure sensor 24 continuously decreases and returns to the initial pressure preset value, and the butt joint hole 22 is moved synchronously during the movement of the inner support plate 21, the overlapping area of the butt joint hole 22 and the air outlet hole 20 decreases, the cooling fan 19 works and the amount of gas discharged into the inside of the pressing sleeve 25 along the air outlet hole 20 and the butt joint hole 22 decreases, thereby avoiding the amount of gas in the pressing sleeve 25 being too large at this position and the pressing force of the pressing sleeve 25 being too large to affect the normal operation comfort of the person.

[0047] At the same time, the pressure value detected by the pressure sensor 24 located above decreases, the control box 3 controls the telescopic part 23 at this position to start and the output end to lengthen, the output end of the telescopic part 23 drives the inner support plate 21 to move away from the end of the horizontal frame 17, the pressing force of the pressing sleeve 25 to the arm of the person increases, the pressure value detected by the pressure sensor 24 continuously increases and reaches the pressure preset value, thereby ensuring the friction limiting effect of the pressing sleeve 25 and the anti-slip pad 28 to the arm of the person, and the butt joint hole 22 is moved synchronously during the movement of the inner support plate 21, the overlapping area of the butt joint hole 22 and the air outlet hole 20 increases, the amount of gas introduced into the inside of the pressing sleeve 25 along the air outlet hole 20 and the butt joint hole 22 by the cooling fan 19 increases, the expansion amount of the pressing sleeve 25 increases and the pressing force applied to the arm of the person increases, which together ensures the friction pressing effect of the pressing sleeve 25 and the anti-slip pad 28 to the arm of the person at different inclination angles.

[0048] And since the inclination angle of the arm of the person changes continuously during the continuous operation, according to the above process, the plurality of inner support plates 21 continuously move and adjust the overlapping area of the butt joint hole 22 and the air outlet hole 20, the amount of gas in the inside of the pressing sleeve 25 continuously changes, and the amount of gas discharged by the plurality of discharge holes 27 continuously changes, thereby further improving the pulse cooling and sweat removal effect of the arm of the person by means of the wind force of the change, avoiding the influence of the normal use effect of the person caused by long-term use of the tea picking machine and high temperature sweating.

[0049] If the handle 2 is loosened due to collision of the collecting bucket 29 or slippage between the palm and the handle 2, etc. during continuous use, the seat 1 and the collecting bucket 29 on one side, etc. fall downward synchronously under the action of gravity, the pressing sleeve 25 is elastically pressed against the arm of the person and is located above during the process, the seat 1 is reversely rotated under the action of the torsion of the torsion spring seat 13 and drives the rotating sleeve 14 to reversely rotate, the pressing force of the pressing sleeve 25 against the arm of the person continuously increases, and the pressure value detected by the pressure sensor 24 reaches the maximum pressure value set.

[0050] At this time, in order to avoid the pressing sleeve 25 from being separated from the arm of the person and causing collision with the palm, the control box 3 controls the multiple telescopic parts 23 to be started and the output ends to be elongated to the maximum distance, the telescopic parts 23 drive the inner supporting plate 21 to move to the maximum distance away from the horizontal frame 17, the pressing sleeve 25 is driven by the end of the inner supporting plate 21 to reach the maximum pressing force against the arm of the person, and during the process, the inner supporting plate 21 drives the abutting hole 22 to synchronously move, the overlapping area of the abutting hole 22 and the air outlet hole 20 reaches the maximum value, the amount of gas entering the inside of the pressing sleeve 25 along the air outlet hole 20 and the abutting hole 22 reaches the maximum value, and the amount of gas entering the inside of the pressing sleeve 25 is greater than the amount of gas discharged by the multiple discharge holes 27, the pressing sleeve 25 continuously elastically expands and cooperates with the anti-skid pad 28 to increase the frictional pressing force against the arm of the person, thereby avoiding the horizontal frame 17 from falling downward with the seat 1 and causing collision with the palm of the person, and at the same time, the expansion of the pressing sleeve 25 further drives the moving rod 16 and the rotating sleeve 14 to reversely rotate, which is convenient for the person to re-grip the handle 2 and restore the grip operation on the seat 1, thereby avoiding the seat 1 from driving the collecting bucket 29 at the end, etc. to fall and causing a major safety accident.

[0051] The above process is continuously repeated to use the tea picker to pick tea leaves, and when the picking is completed, the person loosens the operation key 5, the other hand rotates the moving rod 16 and separates from the handle 2, and the tea picker can be taken off.
