As shown in fig. 2-3, the shearing mechanism comprises two mounting bars 7, each arranged in a vertical direction; the two mounting rods 7 are respectively arranged at the left side and the right side of the fixed rod 3; the upper end of the mounting rod 7 is in sliding connection with the first chute 4, and the lower end of the mounting rod 7 is in sliding connection with the second chute 5; the upper sides of the two mounting rods 7 are connected through a first pressure spring 8, and the lower sides of the two mounting rods 7 are connected through a second pressure spring 9; the first pressure spring 8 and the second pressure spring 9 are arranged along the left-right direction; the first pressure spring 8 is arranged in the first chute 4 along the left-right direction; the second pressure spring 9 is arranged in the second chute 5 along the left-right direction; an extension rod 10 is arranged on the mounting rod 7 along the vertical direction; the lower end of the extension rod 10 passes through the through groove 6; the lower end of the extension rod 10 is connected with a shearing knife 11; the shearing blade 11 is disposed in the front-rear direction; the blade parts of the two shearing blades 11 are arranged oppositely; as shown in fig. 4, the anti-slip rubber sleeve 14 is coated on the outer part of the mounting rod 7, so that the hand slip can be effectively prevented, and the operation is more comfortable.

As shown in fig. 2, the shearing blade 11 includes a blade 12 and a blade holder 13, and the blade holder 13 is detachably connected to the lower end of the extension rod 10 (for example, using a screw), and since the shearing blade 11 is generally easy to damage in use, by adopting a structure in which the shearing blade 11 is replaceable, the shearing blade 11 is replaced when the shearing blade 11 is damaged, and the whole harvester is not required to be replaced, so that the cost can be effectively reduced.

As shown in fig. 1, a guide groove 15 is formed on one side, close to the fixed rod 3, of the mounting rod 7 in the vertical direction; the extension rod 10 is correspondingly and slidably connected with the guide groove 15; as shown in fig. 5, the guide slot 15 may be alternatively a dovetail slot structure, and the extension rod 10 may be effectively limited to slide along the direction of the guide slot 15; the mounting rod 7 is provided with a locking member for locking the extension rod 10.

As shown in fig. 1 and 3, the locking member comprises a locking sleeve 16 sleeved on the lower part of the mounting rod 7; the locking sleeve 16 is connected with the mounting rod 7 in a sliding way along the left-right direction; a plurality of positioning grooves 17 are distributed on one side, close to the fixed rod 3, of the extension rod 10 from top to bottom; the mounting rod 7 is connected with the locking sleeve 16 through a third pressure spring 18; the third compression spring 18 is used for enabling the locking sleeve 16 to be inserted and positioned with the positioning groove 17.

As shown in fig. 4, sockets 19 are respectively formed on the left and right sides of the upper end of the top seat 2; the socket 19 is communicated with the first chute 4; the upper end of the mounting rod 7 is provided with a slot 20; the sockets 19 are in one-to-one correspondence with the slots 20; the upper end of the top seat 2 is connected with a U-shaped safety pin 22 through an elastic rope 21; the two ends of the safety pin 22 respectively pass through the two sockets 19 and are correspondingly spliced with the two slots 20 one by one; through the action of the elastic rope 21, on one hand, the elastic force of the elastic rope ensures that the safety pin 22 is inserted and positioned with the slot 20, and on the other hand, the safety pin 22 is effectively prevented from being lost after the safety pin 22 is pulled out; as shown in fig. 6, the cutting edge portions of the two shearing blades 11 are staggered in the vertical direction, and it is possible to ensure complete cutting of the jujube leaves.

As shown in fig. 2, when the harvester is carried or stored, the locking sleeve 16 can be pushed to release the plugging of the locking sleeve 16 with a certain positioning groove 17 on the extension rod 10, and then the extension rod 10 is upwards slid along the guide groove 15 until the locking sleeve 16 can be plugged with the positioning groove 17 at the lowest end on the extension rod 10, so that the whole occupied space of the harvester is reduced, the harvester is more convenient to carry, and at the moment, the harvester can be plugged with the slot 20 through the safety pin 22, the two shearing cutters 11 cannot be close to each other, and the safety is effectively improved.

Similarly, when the wild jujube leaves are required to be harvested, the extension rod 10 slides downwards along the guide groove 15, so that the extension rod 10 extends out of the lower part of the bracket 1, as shown in fig. 1, and then the locking sleeve 16 is inserted and positioned with a certain positioning groove 17, so that when the wild jujube leaves are harvested, the manual operation part is positioned outside the growth height range of the wild jujube leaves, other wild jujube leaves in the dense growth range are prevented from being pressed when the leaves are sheared, and the shielding of the sight is greatly reduced; furthermore, the hand-operated part is moved out of the growth height range of the wild jujube leaves, so that the problem of hand injury caused by sharp points can be effectively avoided.

Because the front side and the rear side between the two shearing blades 11 are open areas, compared with the traditional shearing tool, the two shearing blades can be flexibly and conveniently placed on the two sides of the wild jujube leaves to be sheared; when the shearing knife 11 is placed in place, only the shearing knife 11 and a part of the extension rod 10 can extend into the area where the wild jujube leaves grow, so that the influence on other leaves in the densely-grown area is greatly reduced, and the harvesting accuracy is effectively improved; meanwhile, in order to accurately cut off specific wild jujube leaves in the dense growing area, the shearing knife 11 can be of a smaller length; in addition, compared with the mode of pinching off by hand, the adoption of the shearing knife 11 for cutting can certainly improve the harvesting efficiency.

During harvesting operation, the two mounting rods 7 are pinched by a single hand, the two extension rods 10 are mutually close along the through groove 6, the two shearing blades 11 can be mutually close until the cutting of the wild jujube leaves is realized, after the cutting, the elastic force of the first pressure spring 8 and the elastic force of the second pressure spring 9 are recovered, the shearing blades 11 can be separated again, and harvesting of the next position is facilitated. It should be noted that the purpose of the first compression spring 8 and the second compression spring 9 is that after the kneading action of the mounting bars 7 is released, the two mounting bars 7 can be separated from each other, so that the shearing blade 11 can be separated, the pretightening force of the first compression spring 8 and the second compression spring 9 is not required to be great, and the labor is avoided when the personnel operate. In this technical scheme, the single hand operation ware of gathering can, and operating personnel can conveniently use the other hand to collect the wild jujube leaf that cuts, and the practicality is strong.

It will be understood that the utility model has been described in terms of several embodiments, and that various changes and equivalents may be made to these features and embodiments by those skilled in the art without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof. Therefore, it is intended that the utility model not be limited to the particular embodiment disclosed, but that the utility model will include all embodiments falling within the scope of the appended claims.
