HAND-HELD TOOL HAVING ANTI-DROP DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/140341
Kind Code:
A1
Abstract:
A hand-held tool having an anti-drop device, comprising a handle (10), a connecting rod (20) and the anti-drop device. The anti-drop device connects the handle (10) and the connecting rod (20), and comprises an embedding member (40) and a tightening member (50). The embedding member (40) comprises a base body (41) and a claw portion (43); the base body (41) is provided with a buckle groove (412); the buckle groove (412) is radially recessed in the base body (41), and a side opening (413) is formed on the outer periphery of the base body (41); the claw portion (43) is formed on the side, facing the handle (10), of the base body (41). The tightening member (50) is sleeved on the outer periphery of the claw portion (43) of the embedding member (40). During use, after the buckle groove (412) of the embedding member (40) and a groove (21) of the connecting rod (20) are buckled with each other, the connecting rod (20) is inserted into the handle (10), and the claw portion (43) of the embedding member (40) is sleeved on the outer periphery of the handle (10), and then the claw portion (43) is forced by the tightening member (50) to connect the connecting rod (20) and the handle (10), thereby preventing the connecting rod (20) from dropping off from the handle (10). The present anti-drop device is sleeved on the outer periphery of a connecting portion (13) connected to the handle (10), thus it is not necessary to provide a complicated locking structure inside the handle (10), therefore having the advantages of easy manufacturing and low manufacturing cost.
