Detailed Description

The invention is further described below with reference to the accompanying drawings:

as shown in fig. 1, the present embodiment includes a fixed jaw 5 and a movable jaw 4 hinged to each other in a crossing manner, a gear ring 7 and a cover plate 8 are respectively fixed at the ends of the fixed jaw 5 and the movable jaw 4, and a string bag 6 is installed on the gear ring 7 at the other side opposite to the cover plate 8. The above is a common structure in the prior art, and is not described herein again.

As shown in fig. 1, the innovation of the present invention is: also comprises a support rod, a handle 9 and a traction rope 2. The fixed jaw 5 is fixedly connected with the upper end of the support rod, the handle 9 is hinged with the lower end of the support rod, one end of the traction rope 2 is connected with the movable jaw 4, and the other end of the traction rope is connected with the handle 9. When the fruit clamp is used, the handle 9 is pressed by hand, the handle 9 pulls the traction rope 2, the traction rope 2 pulls the movable jaw 4, the cover plate 8 is close to the gear ring 7, and therefore fruits are clamped.

As shown in fig. 1 or 3, a locking assembly is arranged in the support rod and is connected in series to the traction rope 2. The locking assembly can lock the cover plate 8 after the cover plate 8 is closed, so that the force for opening the cover plate 8 by the fruit force cannot be transmitted to the handle 9 through the traction rope 2, the problem that the long-time continuous work cannot be carried out due to the fact that fingers of an operator are sore due to continuous force application is solved, the labor intensity of the operator is reduced, and the working efficiency is improved.

As shown in fig. 1 or fig. 3, the locking assembly further includes a sliding sleeve 11, a sliding rod 17 and a coil spring 16, the sliding sleeve 11 is slidably mounted in the supporting rod, a blind hole is formed at the lower end of the sliding sleeve 11, the sliding rod 17 is slidably inserted into the blind hole, the coil spring 16 is located at the upper end of the sliding rod 17, and the upper end and the lower end of the coil spring 16 are respectively fixedly connected with the sliding sleeve 11 and the sliding rod 17; the lateral wall of the sliding sleeve 11 is provided with a radial through hole, a locking block 13 is arranged in the radial through hole in a sliding mode, the inner side of the supporting rod is provided with a yielding groove 14 corresponding to the locking block 13, and a locking groove 12 is arranged on the sliding rod 17 corresponding to the locking block 13. When the cover plate 8 is in an open state, one end of the locking block 13 is abutted against the inner wall of the supporting rod, and the other end of the locking block is inserted into the locking groove 12; when the cover plate 8 is closed, one end of the locking block 13 is inserted into the abdicating groove 14, and the other end of the locking block abuts against the outer wall of the sliding rod 17. The upper end of the sliding sleeve 11 and the lower end of the sliding rod 17 are respectively connected to the traction rope 2, thereby connecting the locking assembly to the traction rope 2 in series.

The working principle is as follows:

when the fruit clamp is used, fruits are placed between the gear ring 7 and the cover plate 8, then the handle 9 is pressed by hands, the handle 9 pulls the traction rope 2, the traction rope 2 pulls the movable jaw 4, the cover plate 8 is close to the gear ring 7 towards the gear ring 7, and the fruits are clamped. After the cover plate 8 moves to the extreme position, the locking block 13 in the locking assembly connected in series on the traction rope 2 is just aligned with the abdicating groove 14, at the moment, the sliding rod 17 with the downward movement trend relative to the sliding sleeve 11 forces the locking block 13 to move along the radial direction and to be inserted into the abdicating groove 14, so that the sliding sleeve 11 is locked on the supporting rod, the pulling and fruit picking processes are avoided, and the opening force of the cover plate 8 is forced by the fruit and cannot be transmitted to the handle 9 through the traction rope 2. At the same time, the other end of the locking piece 13 is disengaged from the locking groove 12, so that the sliding rod 17 can be disengaged from the sliding sleeve 11 and can slide downward relative to the sliding sleeve 11. After one fruit picking action is finished, the handle 9 is loosened, the sliding rod 17 is reset under the action of the spiral spring 16, when the locking groove 12 in the sliding rod 17 is aligned with the end part of the locking block 13 again, one end of the locking block 13 is inserted into the locking groove 12 again, the other end of the locking block 13 is pulled out from the abdicating groove 14, so that the sliding sleeve 11 is reset upwards, the cover plate 8 is enabled to be used for operating the gear ring 7 again, and preparation is made for next picking.

As shown in fig. 1, the support rod is an assembly, and the structure further includes an inner tube 3 and an outer tube 1, and the inner tube 3 is slidably fitted with the outer tube 1 and can be fixed by a locking mechanism. Set the bracing piece to extending structure, make the utility model discloses can use when picking eminence fruit, also make simultaneously the utility model discloses it is more portable.

As shown in fig. 4, the hauling cable 2 is connected with the movable jaw 4, the hauling cable 2 is connected with the handle 9 through the bolt 15, and the length of the hauling cable 2 can be adjusted after the bolt 15 is unscrewed, so that the length of the hauling cable 2 is matched with the length of the telescopic supporting rod.

In specific implementation, the hauling rope 2 is a steel wire soft rope which has the characteristics of firmness, durability and no elasticity.

In specific implementation, a torsion spring is arranged at the hinged position between the fixed jaw 5 and the movable jaw 4, and a cover plate 8 on the movable jaw 4 keeps a movement trend away from the gear ring 7 under the action of the torsion spring.

When the traction rope is specifically implemented, the pulleys 10 can be arranged at the upper end and the lower end of the supporting rod, so that the traction rope can be conveniently guided, and the friction resistance is reduced.
