Quick release tool post structure improvement

This creation is about a "fast-release tool post structure improvement", especially a quick-release tool post structure that can selectively provide a sleeve or a screwdriver tool head.

According to the current structure of the quick-release tool post, as shown in the attached article, it is the "Tool Post Structure Improvement" of the Patent Certificate No. M469991 approved by the Bureau on January 11, 103, the date of application. It is August 7th, 102, and can be analyzed from the attached patent scope and schema, which still has the following defects: it is limited by the setting of C-shaped buckle (30), and the first and second The position of the card groove (19) (24) needs to lengthen the overall length of the sliding sleeve (20) and the connecting end (15) in order to allow the sliding sleeve (20) to have a limited slip on the post (10). This lengthening action will greatly increase the cost of production, and it will not have an advantage in the competition of the industry.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional quick-release tool post structure is actually the goal of the relevant industry to develop and research, and the creator has the idea of thinking and creating for many years. The experience was designed, and after many discussions and trials of sample tests, and many revisions and improvements, this work was launched.

The conventional quick release tool post is limited by the setting of the C-shaped buckle, and the position of the first and second card grooves needs to lengthen the overall length of the sliding sleeve and the connecting end, so that the sliding sleeve can be limitedly slipped on the post. Move, this is the technical problem to be solved.

The present invention provides an improved quick-release tool post structure, comprising: a post body, a sliding sleeve, a spring and a positioning pin, wherein the post body has a circular shaft body, and the outer edge of the shaft body is utilized The formation of a plurality of equiangular sections forms a connecting section having a quadrilateral shape, and through the diameter reduction of the section, a boundary is formed between the shaft and the connecting section, and a positioning bead is embedded in the connecting section, and the recess is recessed. There is a receiving hole, and a magnetic component may be embedded in the side end of the connecting section. The sliding sleeve has a first end and a second end, and a driving hole of a quadrangular shape is penetrated between the first end and the second end. A card groove is disposed adjacent to the first end of the ring, and the card groove is connected to the driving hole by using a guiding surface toward the second end, and a corner is cut in the center of each side wall of the driving hole, and the spring is The positioning pin is sequentially placed in the receiving hole of the post body, and then the sliding sleeve is sleeved on the connecting portion by the driving hole, and the positioning pin is clamped into the card groove by the spring pushing or through the first end. Reciprocating with the retaining edge, allowing the sliding sleeve to be in the post Made on limited slip, thereby, serve to obtain a quick-release coupling lever tool structure improvers.

The creation provides an improved structure of the quick release tool post, which utilizes the cooperation of the spring, the positioning pin and the card groove to minimize the length of the connecting section and the sliding sleeve, and effectively reduces the cost of production, which will compete in the industry. More advantage.
