[0002] The hedge trimmer is mainly used for garden pruning and tea harvesting, usually comprising a handle, a driving mechanism, a transmission mechanism and a blade mechanism, the driving mechanism provides power to drive the blade mechanism through the transmission mechanism, the work of the electric motor makes the gear rotate, the eccentric circular plates on the gear rotate with the gear, and drive the shearing blade to reciprocate relatively to realize pruning work.

[0003] After long-term use of the hedge trimmer tool bit, it will be blunt due to wear and tear, resulting in a significant decrease in pruning efficiency. If the tool bit is not replaced and maintained, the continued use of the worn tool bit may produce unstable shearing force during operation, increasing the risk of operation, and even causing accidents. Moreover, if the tool bit is not replaced for a long time, it may cause excessive wear of the tool bit, thereby damaging other parts of the hedge trimmer and increasing maintenance costs. Secondly, the hedge trimmer tool bit generally has a pruning tool bit and a grass cutting tool bit, which need to be replaced in different use environments to achieve the purpose of pruning and grass cutting. The user needs to replace the tool bit according to different use conditions.
