Detailed Description

Example, see figure 1: high branch shears comprises a pipe body 10. The upper end of the pipe body 10 is fixed with a clamping member 90, and the clamping member 90 may be a two-half structure so as to be clamped at the upper end of the pipe body 10 after being connected together by a bolt. The holder 90 has a holder 20 fixed therein. The holder 20 may be a cast aluminum member. The fixed frame 20 is provided with a movable knife 31, a fixed knife 32, a motor 40, a power supply 50, a plate loading machine system 60 and other components. Wherein, the movable knife 31 is pivoted on the fixed frame 20, and the fixed knife 32 is fixed on the fixed frame 20; the movable knife 31 is matched with the fixed knife 32; the motor 40 provides driving force for the moving blade 32; the power source 50 provides power to the motor 40; the upper trigger system 60 controls the operating state of the motor 40. That is, the movable knife 31 can swing under the driving of the motor 40 to form a shearing action of repeated opening and closing with the fixed knife 32; the motor 40 is normally capable of forward and reverse rotation to effect reciprocating oscillation of the movable blade 31.

Further speaking:

the tubular body 10 is a telescopic tube and thus includes a lower tube 11 and an upper tube 12 inserted at a lower portion in an upper inner cavity of the lower tube 11. Also, a lower trigger system 70 is provided at the lower end of the lower tube 11. The lower trigger system 70 is signally connected to an associated signal line 80, the associated signal line 80 having a plug 81 at an upper end thereof. The upper trigger system 60 is connected to a socket 65, and the plug 81 mates with the socket 65. That is, the plug 81 can be inserted into the receptacle 65 to connect signals. In this manner, the upper trigger system 60 can control the starting, closing, forward rotation, and reverse rotation of the motor 40; and after the plug 81 and the socket 65 are plugged together, the lower trigger system 70 can transmit the control signal of the lower trigger system 70 to the upper trigger system 60 through the associated signal line 80, and the starting, closing, forward rotation and reverse rotation of the motor 40 are also realized by the control part of the upper trigger system 60. Of course, the signal lines are commonly associated, and many common ways may be used. And, the related signal line 80 is inserted into the lower tube 11 and the upper tube 12, and the upper end of the related signal line 80 is fixed on the upper portion of the upper tube 12 by a pressing block 82, and the lower end of the related signal line 80 is also fixed on the lower portion of the lower tube 11 by a pressing block 82. To achieve the length variation, the associated signal line 80 has a resilient spiral shape in the middle, similar to a telephone line. Thus, the trimming of the upper branches can be achieved by increasing the length of the tube 10, and the lower trigger system 70 is located at the lower portion of the tube 10 for easy handling, and does not affect the handling achieved by the upper trigger system 60 when the tube 10 is shorter. Meanwhile, the associated signal line 80 is located inside the tube 10, so that the wiring is compact, and the condition of cutting off the associated signal line 80 is avoided. And, the upper and lower end portions of the related signal line 80 are fixed by the pressing block 82, further ensuring the compactness of the wiring.

Optimizing:

referring to fig. 6, a locking device 13 is provided at the upper opening of the lower tube 11 by means of screw fastening, and the locking device 13 is matched with the side wall of the upper tube 12. The locking device 13 can be used in a conventional manner. In this embodiment, the locking device 13 includes a non-closed sleeve 131 which is sleeved on the upper opening of the lower pipe 11 and has a gap 1311, the edges of the gap 1311 of the sleeve 131 are provided with an outward extending snap-

gauge

1312, and 2 snap-gauges 1312 are hinged with a snap-fastener 132, and the cross section of the snap-fastener 132 is "U" shaped. After the snap 132 is rotated to be caught on the outer side of 2 catching plates 1312, the inner diameter of the sleeve 131 can be reduced, thereby locking the sidewall of the upper handle 12.

And (4) continuing optimization:

the trigger system may be used in the usual manner. Referring to fig. 3, in the present embodiment, the upper trigger system 60 includes: an upper trigger 61 hinged on the fixing frame 20 at the middle part, an upper reset torsion spring 62 matched with the upper trigger 61, an upper magnet 63 fixed on the upper end of the upper trigger 61, an upper Hall induction plate 64 fixed on the fixing frame 20 and having 3 upper induction points 641. Wherein, the 3 upper sensing points 641 of the hall sensing plate 64 are all signal-connected to the motor 40, and the upper magnet 63 is matched with the 3 upper sensing points 641. That is, after the upper trigger 61 is pulled, the upper magnet 63 triggers different upper sensing points 641, so that the motor 40 can be turned on, off, forward and reverse. In particular, the association of the upper sensing point 641 with the operating state of the motor 40, can be performed in a conventional manner. Such an upper trigger system 60 is simple in construction and easy to operate.

As shown in connection with fig. 7, the lower trigger system 70 includes: a lower trigger 71 having a middle portion hinged to a lower end portion of the lower tube 11, a lower return torsion spring 72 engaged with the lower trigger 71, a lower magnet 73 fixed to an upper end of the lower trigger 71, and a lower hall sensor 74 having 3 lower sensor points 741 fixed to a lower end portion of the lower tube 11. Meanwhile, the associated signal line 80 is a three-wire signal line, the plug 81 is a three-wire plug, and the socket 65 is a three-wire socket as shown in fig. 4. And, the three lines of the associated signal line 80 are respectively connected to a lower sensing point 741, the three electrodes of the socket 65 are respectively connected to an upper sensing point 641, and the lower magnet 74 is matched with 3 lower sensing points 741. That is, the connection of the related signal line 80 allows the lower sensing points 741 to correspond to the upper sensing points 641 two by two, and after the user pulls the lower trigger 71, the lower magnet 73 triggers different lower sensing points 741, so that the same trigger signal as that of the 3 upper sensing points 641 can be given to the control part of the upper hall plate 64, and the operation state of the motor 40 can be changed. Therefore, the operation and the control are more convenient, and the pertinence is stronger.

In addition:

as shown in fig. 2, the power output shaft of the motor 40 is power-connected to the power input end of a planetary transmission 41, and a driving gear 411 is fixed to the power output end of the planetary transmission 41. That is, the high rotation speed and low torque of the motor 40 is converted into the low rotation speed and high torque by the planetary transmission 41, so that the driving gear 411 drives the relevant components. Meanwhile, the lower portion of the movable blade 31 is pivotally connected to the fixed frame 20, and a swing gear 311 is fixed to the lower portion of the movable blade 31, and the driving gear 411 is matched with the swing gear 311. That is, the driving gear 411 engages the swing gear 311. Thus, when the motor 40 is operated, the driving gear 411 rotates, and the swing gear 311 swings the movable blade 31.

As shown in connection with fig. 5, the power supply 50 is a lithium battery pack. That is, the fixing frame 20 may be provided with a clamp 21 for clamping the power supply 50, and the clamp 21 may be provided with an electrode plate 211 electrically connected to the power supply 50. Thus, external power and the use of long connecting wires and the use of power connecting wires arranged outside the tube 10 are avoided.
