Post and quick release structure including the same

This creation is related to the quick release structure, in particular to a post and a quick release structure including the post.

Pressing, generally used for connecting the joint structure of the driver rod, having a joint and a post, the joint is connected by a torsion device, and a shaft body of the telescopic hole is arranged on the outer side of the joint, and is extended and contracted A steel ball is arranged in the hole, a fixed rib is arranged on the outer surface of the shaft, and a spring is arranged on the outer circumference, and a sleeve is provided with a concave inclined surface and is formed by the rib. When the shaft has a groove ring When the screwdriver rod is to be inserted into the joint, the sleeve can be pressed inwardly by a single spring to allow the steel ball to have space to enter the concave slope of the sleeve, so that the screwdriver rod is pushed in instantaneously, and the spring automatically rebounds. The steel ball is reset to the telescopic hole and the card is in a locked state in the groove ring of the shaft of the screwdriver rod. This is the type of quick release structure disclosed in TWM369224 and TW354003.

However, in such conventional assembly techniques, the structure of the post is generally not strong enough. When the post is assembled with a torsion device and the torsion device rotates to drive the joint structure to lock a screw, When the resistance is large, the post often cannot withstand strong torque and deform or break, resulting in the need to replace the new joint structure, increasing work inconvenience and wasting cost.

In addition, when the hammer rod is to be assembled, the sleeve of the joint must be pressed first, and only the spring can be pushed in one direction to connect the screwdriver rod, so that the sleeve needs to be pressed repeatedly to take the screwdriver rod. The replacement or replacement causes the connection of the driver rod to be limited and not quick and inconvenient, thereby reducing the efficiency at work. Moreover, the shape of the insertion end of the screwdriver rod produced by different manufacturers is not completely the same, and the distance between the end face of the insertion rod end of the screwdriver rod and the groove of the shaft is at least several different sizes, but the conventional screwdriver The joint of the rod is only considered for one type of structure, which results in the lack of multiple applicability in use, and the screwdriver rod obtained by the user often cannot be inserted into the joint of the screwdriver rod. In combination, the utility of the joint of the screwdriver rod is greatly affected, and there is a drawback that needs to be improved.

Therefore, it is necessary to provide a novel and progressive post and a quick release structure including the post to solve the above problems.

The main purpose of the present invention is to provide a post and a quick release structure including the post. The post has a more durable and stronger structure, which can effectively avoid deformation or breakage of the post. The quick release structure can be used for various purposes. Different sizes of the driver rods are assembled and disassembled quickly.

In order to achieve the above object, the present invention provides a post and a quick release structure including the post, the post includes a first set of joints, a second set of joints, and a first joint of the first set and the first a buffering section of the two sets of joints, the first set of joints being connected to a rod body of a quick release structure, the second set of joints being for cooperating with a torsion device, the buffer section comprising a notch And the two ends of the buffer segment each have an enlarged portion, and each of the expanded portions is gradually expanded and connected to the first assembly portion and the second assembly portion.

The present invention further provides a quick release structure, comprising the post as described above, further comprising a rod body, a first elastic element, a second elastic element, a movable inner cylinder and a sleeve, the rod system and The first set of joints of the post are assembled. An insertion slot is provided in the interior of the rod for the first An elastic element and the movable inner cylinder are accommodated therein, and an arc-shaped circular groove of a ring of the same diameter is formed, and an outer diameter of the insertion groove is formed to be adjacent to the edge of the insertion groove, The outer side of the rod body is provided with a through-hole card groove for a flat ring-shaped snap ring, and a pivoting portion of the telescopic hole is provided for a steel ball, and the second elastic element and the sleeve The sleeve is disposed on the outer side of the pivoting portion, and a ring groove is disposed on the inner wall of the sleeve opposite to the telescopic hole, and a locking groove is disposed in the movable inner cylinder. Wherein, the rod body can be pushed in or withdrawn by different size of the driver rod to push the first elastic element and the second elastic element to cause the steel ball to enter the locking groove or one of the driver rods along the ring groove The ring groove forms a card.
