Description

Technical Field

[0001] The present invention relates to a hand tool socket joint structure, and more particularly to a hand tool socket joint structure in which the clamping member is in the shape of a round rod. When the screwdriver bit is engaged with or disengaged from the first engaging portion, the clamping member rolls within the groove and the third surface, thereby generating rolling friction between the screwdriver bit and the clamping member. This allows the round rod structure of the clamping member to be evenly worn, thereby achieving an optimal use state. Background Art

[0002] The conventional hand tool sleeve joint structure has the following defects: the contact surface where the clamping element is fixed is easily damaged due to long-term friction, which in turn causes the clamping element and the screwdriver head to be locked in an uncertain manner.

[0003] As mentioned above, the clamping element is a slightly U-shaped clamping body disposed in the limiting groove, and the limiting groove needs to be processed into a surrounding shape, so the limiting groove has a higher processing cost.

[0004] In view of the above-mentioned shortcomings of conventional hand tool socket connector structures, the creators of this invention, with their many years of manufacturing, production and design experience in the industry, have finally come up with a product with a hand tool socket connector structure that can solve the conventional shortcomings. Utility Model Content

[0005] The problem to be solved by this utility model is that in conventional hand tool socket joint structures, the clamping element is a slightly U-shaped clamping body disposed within the limiting groove. The clamping element is engaged and locked with the screwdriver bit by a fixed contact surface, that is, sliding friction is generated between the clamping element and the screwdriver bit. In the hand tool socket joint structure of the present invention, the clamping member is in the form of a round rod. When the screwdriver bit is engaged or disengaged from the first engaging portion, the clamping member rolls within the groove and the third surface, generating rolling friction between the screwdriver bit and the clamping member, and the round rod structure of the clamping member is evenly worn.

[0006] Technical means to solve the problem: A hand tool sleeve joint structure includes: a main body provided with a first fitting portion, a first surface, a groove, a through groove, a first abutment and a first annular groove; a sleeve is sleeved with the main body, the sleeve can be axially displaced a distance on the main body, the sleeve is provided with a first receiving groove, a second surface, a third surface, a second abutment, a third abutment, a second receiving groove, a fourth abutment and a first end; a clamping member is in the shape of a round rod, the clamping member is provided with a second end; an elastic element can make the sleeve return to its original position after displacement; a buckle is buckled at the first annular groove, the sleeve is displaced on the main body, the buckle can abut on the fourth abutment to prevent the sleeve from falling out of the main body, and the buckle can limit the maximum distance of the sleeve displacement.

[0007] Compared with the prior art, the following effects are achieved: the clamping member is in the shape of a round rod. When the screwdriver bit is engaged with or disengaged from the first engaging portion, the clamping member rolls within the groove and the third surface to control engagement or disengagement. Rolling friction is generated between the screwdriver bit and the clamping member, and the round rod structure of the clamping member is evenly worn. The clamping member has the advantage of being able to be used for a long time and having a secure engagement. The second surface is aligned with the clamping member, and the second surface restricts the clamping member from escaping from the groove. After the collar is displaced relative to the body, the third surface is aligned with the clamping member, allowing the clamping member to shift within the groove, preventing the clamping member from protruding from the first engaging portion. After the collar is displaced, the fourth abutting edge is restricted by the retaining ring, and the groove does not protrude from the first end.

[0008] To help examiners and those skilled in the art fully understand the effectiveness of this invention, the structure and composition of this invention are described below with accompanying diagrams and figure numbers. However, the following description is merely an example of an embodiment of this invention and is not intended to limit this invention in any form. Therefore, any modifications and changes made within the spirit of this invention shall remain within the scope of protection of this invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Please continue reading Figure 13 As shown, Figure 13 This is a three-dimensional diagram of the third embodiment of the hand tool sleeve joint structure of the present invention. In this embodiment, the driving portion 17 is in the shape of a polygonal head and has a screwdriver joint structure.

[0052] Please continue reading Figure 14 As shown, Figure 14 This is a perspective view of a fourth embodiment of the hand tool sleeve joint structure of the present invention. In this embodiment, the driving portion 17 is in the shape of a ratchet, and the body 10 is a ratchet structure. The body 10 can be pivotally mounted on a wrench body 10.

[0053] The structural advantages of the hand tool sleeve joint structure of this invention are:

[0054] 1. The clamping member 30 is in the shape of a round rod. When the screwdriver head 60 is fitted into or disengaged from the first fitting portion 11, the clamping member 30 is rolled within the groove 13 and the third surface 23 to control the clamping or disengagement. Rolling friction is formed between the screwdriver head 60 and the clamping member 30. The round rod structure of the clamping member 30 can be evenly worn, and the clamping member 30 has the advantage of being securely clamped for a longer period of use.

[0055] 2. The second surface 22 is aligned with the clamping member 30, and the second surface 22 restricts the clamping member 30 from escaping from the groove 13. After the collar 20 is displaced relative to the body 10, the third surface 23 is aligned with the clamping member 30, so that the clamping member 30 can be displaced in the groove 13, so that the clamping member 30 does not protrude from the first fitting portion 11. After the collar 20 is displaced, the fourth abutting edge 261 is restricted by the buckle 50, and the groove 13 does not protrude outside the first end 282 to protect the clamping member 30 from escaping from the groove 13.

[0056] 3. The second abutment 24 abuts against the second end 31 , or after the collar 20 is displaced, the fourth abutment 261 abuts against the buckle 50 , and the collar 20 is only displaced between the clamping member 30 and the buckle 50 .

[0057] 4. The second surface 22 slides against the first surface 12. When the collar 20 is rotated, the second surface 22 can drive the first surface 12, so that the body 10 rotates along with the collar 20, thereby achieving rapid rotation.

[0058] 5. The clamping member 30 is worn out after long-term use. The buckle 50 can be removed and the sleeve 20 can be pushed to further compress the elastic element 40. The groove 13 is exposed outside the first end 282. The clamping member 30 can be removed from the groove 13 and replaced with a new clamping member 30 assembled in the groove 13.

[0059] Therefore, the hand tool sleeve joint structure of this invention has industrial applicability, novelty and progress, and can truly meet the application requirements of a utility model patent, so an application is filed in accordance with the law.
