Abstract
An engaging head implemented in a movement converting mechanism to engage with a screwed rod comprises an attachment body, a gear part, and a resilient pre-loading element. The attachment body has a pushing sidewall. The gear part has an inner surface facing the pushing sidewall of the attachment body, and an opposite outer surface provided with gear teeth. The resilient pre-loading element is mounted between the pushing sidewall of the attachment body and the inner surface, and has a side abutting against the pushing sidewall and another side abutting against the inner surface of the gear part. Being compressed between the pushing sidewall and the inner surface, the resilient pre-loading element thereby exerts a pre-loaded engagement pressure that results in a deflection of the gear part to ensure an adequate engagement of the gear teeth with the screwed rod.
