Utility model content

The main purpose of the present utility model is to provide a socket positioning structure of the socket rod, which can improve the stability of the socket assembly positioning and the balanced torsional force actuation when the socket rod is assembled with the sleeve. Thereby improving efficiency and quality. the

For reaching above-mentioned purpose, the technical scheme of the present utility model is:

A socket positioning structure for a socket connecting rod, comprising a connecting rod for socketing a socket, the inner edge of the socket part at the front end of the connecting rod is provided with a clamping unit for positioning the socketed sleeve, wherein the clamping The control unit is composed of at least two positioning pieces and an elastic component. The two positioning pieces are placed at the corresponding positioning holes of the socket part, and the elastic component is elastically stretched and placed between the two positioning pieces. The two positioning pieces Affected by the elastic component, its edge protrudes or hides at the edge of the sleeve portion. the

The two positioning pieces can be circular steel balls, and the elastic component is composed of an elastic body and a push piece, and a positioning hole for the two positioning pieces is formed at an appropriate place in the radial direction on the inner edge of the sleeve part of the connecting rod. An accommodating hole for the elastic body and the pushing member is formed at an appropriate place on the axial inner edge, and then a cover plate is used to seal and fix it, so that one end of the pushing member is driven by the elastic force of the elastic body to position the two The part is exposed or retracted at the positioning hole. the

The pushing member is a convex-shaped rod body, which pushes and contacts the outer ends of the two positioning members to form a tapered oblique pushing surface or a concave arc-shaped pushing surface. the

The pushing member is a spherical steel ball. the

By adopting the above scheme, the utility model utilizes the elastic component to simultaneously drive the two positioning parts to perform the elastic action of protruding and contracting, so that when the sleeve of the connecting rod is assembled with the positioning sleeve, it can achieve a stable and stable position. The structural characteristics of force balance, thereby improving the efficiency, quality and practical value of socket tools. the

The following describes the utility model in detail in conjunction with preferred embodiments and accompanying drawings. the

Detailed ways

Please refer to Fig. 2 to Fig. 5, the socket positioning structure of the sleeve connecting rod of the present invention includes a connecting rod 10, and one group is arranged at the front end of the connecting rod 10, and is used for clamping of the positioning sleeve 31. Unit 20, where:

The connecting rod 10 is a generally long rod-shaped object, one end of which is provided with a sleeve hole 11 for a wrench tool (not shown in the figure), and the other end is protruded to form a sleeve portion 12 . The sleeve portion 12 is square, and can be inserted into the inner edge of the corresponding end of the sleeve 31, and the sleeve portion 12 has a positioning hole 121 formed on both sides at an appropriate position in the radial direction. An accommodating hole 122 is formed by drilling inward at an appropriate place for the assembly of the clamping unit 20 . the

The clamping unit 20 is composed of at least two positioning pieces 21 and an elastic assembly 22, the two positioning pieces 21 can be circular steel balls, and are respectively arranged at the positioning holes 121 opposite to the sleeve portion 12; and the elastic assembly 22 Then, the elastic expansion and contraction action structure is arranged between the two positioning parts 21, so that the two positioning parts 21 are subjected to the elastic force of the elastic component 22, so that the end edges thereof are exposed or hidden in the positioning hole 121. action. the

Based on the above, it is further explained that the structure of the elastic component 22 of the present utility model can be shown in Figure 2 to Figure 6, which is composed of an elastic body 221 and a push piece 222. When assembling, the elastic body 221 and the push piece After the supporting parts 222 are arranged in the accommodating holes 122 in sequence, a cover plate 23 is used to close the opening at the outermost end thereof. And the push piece 222 can be a spherical steel ball as shown in Figure 2 to Figure 4, or a rod body in a convex shape, and one end of it pushes and contacts the outer ends of the two positioning pieces 21 to form a tapered oblique The pushing surface 223 as shown in FIG. 5 , or the concave arc-shaped pushing surface 224 as shown in FIG. 6 , can facilitate the pushing part 222 to drive the two positioning parts 21 to move telescopically. the

Accordingly, by virtue of the above components, the elastic component 22 simultaneously drives the two positioning members 21 to perform elastic movements of outward protrusion and inward contraction, so that the socket portion 12 of the extension rod 10 can be set with the positioning sleeve 31 At the same time, the structural characteristics of stability and balanced force are achieved, thereby improving the efficiency, quality and practical value of the socket tool. the
