Connection locking device

Abstract

The invention relates to the technical field of garden devices, in particular to a connection locking device. The connection locking device comprises a first locking block, a second locking block, a first connecting rod, a second connecting rod, a first return spring, a second return spring, a first operating lever and a second operating lever. In use, external force acts on the first operating lever and the second operation lever, so that the first locking block and the second locking block are rotated with a connecting pin as a fulcrum, the first locking block and the second locking block compress the first return spring and the second return spring correspondingly and retract, at the moment, the connection locking device can be installed into a base connecting hole of a prime mover anda bottom plate connecting hole of a transporting trolley. When the acting external force disappears, under the acting force of the first return spring and the second return spring, the first locking block and the second locking block clamp the bottom plate connecting hole of the transporting trolley, the first operating lever and the second operating lever are clamped at the upper end of the baseconnecting hole of the prime mover, and the device achieves the effect of connecting and locking the prime mover and the transporting trolley.

Description

technical field [0001] The present application relates to the technical field of garden equipment, in particular to a connection and locking device. Background technique [0002] At present, domestic fruit tree pruning is mainly done manually, which is labor-intensive, low-efficiency, and easily breaks branches during pruning. The use of pneumatic pruning devices can greatly reduce labor intensity, improve operating efficiency and quality, and improve the mechanized management level of orchards. Pneumatic pruning technology has been widely used in pruning operations in European and American orchards. Southern orchards are mainly planted in southern hills and mountains, and the special topography hinders the large-scale promotion and application of pneumatic pruning technology in orchard pruning operations. In order to realize the mechanization of orchard pruning in hilly and mountainous areas, the use of a mounted pneumatic pruning machine can effectively solve this proble...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing pneumatic trimming devices are independent operating pneumatic trimmers, and the mounted pneumatic trimmer is rarely used. The pneumatic trimmer and the transport trolley generally use the side baffle and iron wire of the transport trolley to fix the pneumatic trimmer. This connection method is disassembled. It is inconvenient to install and the trimmer has the risk of tipping over, which makes it difficult to meet the safety and stability requirements of the mounted pneumatic trimmer during use
