Description

Technical Field

[0001] This utility model relates to a connector and a rod. Background Technology

[0002] In modern sports equipment, telescopic poles are often used to make the equipment more portable. However, some telescopic poles use threaded connections, which require a long time to tighten or loosen when the pole is long. Others use a combination of a hole and a telescopic component. When the pole needs to be extended and fixed, the inner pole is pulled to the desired position. At this time, the telescopic component installed on the inner pole corresponds to the hole, and the telescopic component pops out under the action of the elastic component and passes through the hole. When the pole needs to be retracted and reset, the telescopic component needs to be manually pushed inward to disengage the end of the telescopic component from the hole. This operation is inconvenient and poses a risk of cutting the operator's hands. Utility Model Content
