Structural improvements of socket tools

Abstract

This invention relates to a structural improvement of a socket tool, comprising an outer shell, a sliding member disposed inside the outer shell, a spring disposed between the sliding member and the outer shell, and at least one retaining element. The invention is characterized by at least one mounting groove circumferentially formed around the outer edge of the sliding member, allowing the retaining element to be elastically deformed and assembled within the mounting groove. Furthermore, the outer shell has a first stop and a second stop at predetermined positions, spaced apart from each other. When the sliding member slides longitudinally within the outer shell, it is in a sliding or limited state by contact between the retaining element and the first stop. The spring is disposed between one end of the sliding member and the second stop, and the free length of the spring is at least greater than the effective stroke length of the sliding member. The number of coils of the spring is configured such that when the spring is not under stress, it extends axially to form a multi-coil long compression stroke. This structure combines structural strength and ease of disassembly, among other advantages.

Claims

1. An improved structure of a socket tool, comprising a housing, a sliding member disposed inside the housing, a spring disposed between the sliding member and the housing, and at least one retaining element, characterized in that: at least one mounting groove is provided around a predetermined position on the outer edge of the sliding member, and the retaining element is elastically deformable and disposed in the mounting groove; a first stop and a second stop are provided at a predetermined position on the housing, spaced apart from each other, such that when the sliding member is mounted in the housing and slides longitudinally, it is in a sliding or limited state by contact between the retaining element and the first stop; wherein the spring is disposed between one end of the sliding member and the second stop, the free length of the spring is at least greater than the effective stroke length of the sliding member, and the number of coils of the spring is configured such that the spring extends axially in a multi-coil long compression stroke state when not under force.

2. A structural improvement of the socket tool as described in claim 1, wherein the free length of the spring is at least twice its outer diameter.

3. A structural improvement to the socket tool as described in claim 1, wherein the effective number of coils of the spring is greater than 5.

4. An improvement to the sleeve tool as described in claim 1, wherein the axial length of the spring before compression is more than 1.5 times its length after compression.

5. An improvement to the structure of the sleeve tool as described in claim 1, wherein the mounting groove of the sliding member is C-shaped, and the retaining element is a C-shaped ring.
