Description

Insulated tool screwdriver head quick release structure

This invention relates to a quick-release structure that can quickly provide a screwdriver head for replacement.

According to the presently known tool head adapter, as disclosed in the Chinese Patent Certificate No. I650213, it is mainly composed of a base (11), a sleeve (21) and an elastic member (31). Among them, the base (11) has a cylinder (13) at one end, a chamber (131) is formed in the cylinder (13), and the front end of the chamber (131) is formed with the chamber (131). A communicating opening (133) is used for a tool head (100) to be inserted into the chamber (131) through the opening (133). The side wall of the barrel (13) has a first through hole (15), a The second through hole (17) and an annular groove (19), the first through hole (15) is located behind the second through hole (17), and the first through hole (15) and the second through hole (17) communicate with the chamber (131), the first through hole (15) and the second through hole (17) can respectively accommodate a first positioning bead (151) and a second positioning bead (171), and the ring groove (19) is fastened A buckle (191), the sleeve (21) is slidably provided on the barrel (13), the inner wall of the rear end of the sleeve (21) has a convex ring (23), and the inner wall of the sleeve (21) The side wall has a stop point (25), and the buckle (191) is against the stop point (25) to prevent the sleeve (21) from being separated from the barrel (13), and the sleeve (21) is moved from the back to the stop point (25). There is an inclined plane section (27) at the front, and the inclined plane section (27) is tapered from the back to the front. The elastic member (31) is fitted in the barrel (13) and resists the convex ring (23) and the The buckle (191) provides elastic force for the sleeve (21) to move backward.

However, the conventional structure as mentioned above still has the following problems in practical application: the tool head rod uses the elastic member (31) to resist the convex ring (23) and the buckle. ring (191), the elastic member (31) will gradually become fatigued after the pressing operation, so that the elastic member (31) can no longer reliably support it, thereby losing the ability to tightly fix the tool head (100). By.

Therefore, how to develop and improve the above-mentioned shortcomings of the conventional tool head adapter is actually a research and development goal that the relevant industry needs to work hard on. In view of this, the author of the present invention thought about the idea of creation and used many years of experience. After careful design, many discussions, sample testing, and many revisions and improvements, this creation was launched.

Conventionally, the tool head adapter uses an elastic member for abutment and positioning, but there is a risk that the elastic member will easily fatigue. This is a technical problem to be solved.

This invention provides a quick-release structure for a screwdriver head of an insulating tool, which includes: a body, and a sliding sleeve that is worn on the body, wherein a polygonal hole is formed at the front end of the body to provide a screwdriver head for insertion , a connecting rod extends from the rear end so that the body can be connected with a driving member through the connecting rod. At least one perforation is provided on the outer periphery of the body and a buckle groove is arranged around it. The perforation is connected to the polygon. hole, so that the perforation can provide positioning beads for accommodation, and a stop buckle is provided in the buckle groove. An annular groove is provided behind the inner wall of the sliding sleeve, and a protruding rib is used to separate the annular groove in the annular groove. There is a first accommodation space in the front and a second accommodation space in the rear. The rib also has a two-way slope, which can be used when the sliding sleeve slides forward and backward on the body. The guidance of the two-way inclined surface allows the buckle to smoothly cross the protruding rib and further snap into the first In the accommodating space or the second accommodating space, the sliding sleeve can be accurately positioned in the pressing or releasing state by utilizing the locking in different spaces, and an annular groove is provided in front of the inner wall of the sliding sleeve. In order to control the protrusion or retraction of the positioning bead by the annular groove, the outer periphery of the sliding sleeve is covered with a holding member with an insulating effect, thereby obtaining a quick screwdriver head of an insulated tool. Destructured person.

This invention provides a quick-release structure for the screwdriver head of an insulating tool, which utilizes the mutual cooperation of the protruding ribs, the first accommodation space, and the second accommodation space to facilitate the front and rear sliding of the sliding sleeve. The sliding sleeve can be accurately positioned in the pressing or releasing state without installing an additional spring. In this way, there is no problem that the quick-release structure can no longer be used due to fatigue of the spring elasticity, and the service life is long.
