Description

Screwdriver tool quick release lever structure

This creation is about a "starter tool quick release lever structure", especially a quick release lever structure that can provide two different outer diameter sizes of the screwdriver tool head in the same structure.

According to the hand tool, the hand tool can quickly and conveniently lock or unscrew the bolt, the nut and the like, and has the effect of assisting the worker to make the action of locking or opening the article more simplified.

However, because the general joint parts have different styles, if a different hand piece is locked or unscrewed, a hand tool that cooperates with it is prepared, which will inevitably result in a large number of hand tools, which is unfavorable for carrying. In addition, the storage space also takes up too much space; in view of this, the manufacturer has developed a replacement hand tool to achieve a hand tool that can be used in a variety of specifications.

At present, the structure of the replacement hand tool is numerous, but it is only used by a tool post to replace a variety of tool heads (such as a cross tool head, a word tool head or a star tool head). Because the tool head itself also has a variety of outer diameter dimensions, if the traditional tool The post can only be provided with a tool head of one size for assembly, which is bound to cause inconvenience in use.

Therefore, how to carry out research and development and improvement on the shortcomings of the above-mentioned conventional structures is indeed the goal of the relevant industry to develop and research. The present creator has in this view, thinking and creative ideas, and designing with years of experience, After many discussions and trials of sample tests, and many revisions and improvements, this work was launched.

Conventional tool posts can only provide a tool head of outer diameter size for assembly, which is a technical problem to be solved.

The present invention provides a quick release lever structure for a screwdriver, comprising: a quick release body, a sliding sleeve, an elastic member and a buckle; wherein the rear end of the quick release body is provided with a set of joints, and the front end is reduced in diameter. a first rod hole and a second card hole are formed in the side of the connecting portion, and the second card hole has a smaller aperture than the second card hole. a first card hole, wherein the first tool hole or the second card hole is respectively provided with the first tool hole or the second card hole to be locked after the penetrating, and the outer periphery of the post is set Having at least one first radial perforation penetrating the first card hole and at least one second radial perforation penetrating the second card hole, wherein the first radial perforation and the second radial perforation end hole edge are Slightly converged design, can wear the first radial The hole and the second radial perforation respectively provide a first positioning bead and a second positioning bead to be placed after being placed, so that the first positioning bead and the second positioning bead can be slightly curved with the inner arc edge when the placement is completed. Extending into the first card hole and the second card hole, but not falling into the first card hole or the second card hole, the center of the sliding sleeve end surface is arranged in order from the back to the rear and a stepped first receiving groove, a through hole and a second receiving groove, wherein the inner wall of the through hole is provided with a ring groove, and the sliding sleeve utilizes the first receiving groove, the through hole and the second receiving hole The first step of the slot is sleeved on the outer circumference of the post, and the first elastic member is continuously pushed between the sliding sleeve and the quick release body to continuously push the sliding sleeve forward. The receiving groove and the annular groove can respectively avoid the first positioning bead and the second positioning bead, and the edge of the through hole continuously urges the first positioning bead and the second positioning bead to be inward to maintain the position Referring to the clamping force of the tool bit after the penetration, the buckle is mounted on the post in front of the sliding sleeve, and the buckle can be used to stop the Generating forward from the sleeve, thereby, serve to obtain a screwdriver tool by quick-release coupling lever structure.

The present invention provides a quick release lever structure for a screwdriver, and the quick release body can be provided with two different outer diameter size screwdriver heads in the same structure, so that the user does not need to prepare two different ones because of work requirements. The sleeve is replaced, the convenience and applicability of the use are excellent, and the cost of purchasing another sleeve can be saved.
