Description

Sleeve structure improvement and sleeve screwdriver with the same

The present invention provides an improved sleeve structure and a sleeve driver having the same, particularly a sleeve having a magnetically stable workpiece.

According to the conventional sleeve structure with magnetic attracting bolts, there are new patent No. M307496 "Sleeve structure (2)", No. M384743 "Modified structure of magnetic screw drive device" and No. M327772 "Magnetic suction sleeve" The magnet sleeve structure is characterized in that a magnetic body is embedded in the center of the sleeve to achieve the function of adsorbing the workpiece to be operated, but the embedded magnetic body is attracted by the workpiece due to the suction force when the workpiece is separated from the operation. Further, in the center of the sleeve of the "sleeve and screwdriver combination structure improvement" of No. 102205268, there is no space structure for accommodating the magnetic body. Therefore, in view of the lack of the above-mentioned conventional structure, how to develop an innovative structure with more ideal and practicality, the users are eagerly awaiting, and the relevant industry must strive to develop the goal and direction of breakthrough.

The creator aims at the lack of the above-mentioned conventional sleeve structure. The main purpose of the present invention is to provide an improved sleeve structure and a sleeve driver having the effect of magnetically stabilizing the workpiece; and the technical feature of solving the problem, The utility model is characterized in that the magnetic peripheral body is uniformly embedded by the circumferential surface of the sleeve near the opening of the hole to achieve the practical progress of magnetically stabilizing the workpiece.

With this innovative and unique design, this creation can achieve the following effects in comparison with the prior art: due to the improved structure of the creation sleeve and the sleeve driver having the sleeve, the circumferential surface of the hole near the opening is sleeved by the sleeve The magnetic body is evenly embedded to prevent the magnetic body from being attracted by the workpiece due to the suction force to achieve the effect of magnetically stabilizing the workpiece.

Please refer to FIG. 1 for a preferred embodiment of the present invention, but such embodiments are for illustrative purposes only and are not limited by this structure.

In order to further understand the structural design and technology of this creation, we will further explain it in detail with the following: Please refer to Figure 1, a three-dimensional diagram of the embodiment (1) of the present creation. The invention has an improved sleeve structure, which is mainly provided with at least three magnetic bodies 20 uniformly embedded on the circumferential surface of the sleeve opening 11a1 near the opening of the sleeve body 11 . The 20' 20" features a magnetically stable work piece.

The invention has an improved sleeve structure, wherein a circumferential surface of the sleeve opening 11a1 near the opening is provided with three holes 11d 11d' 11d", the hole spacing angle is 120 degrees, and the holes are respectively embedded with a magnetic body 20 20' 20".

The invention has an improved sleeve structure, wherein the sleeve hole 11a1 is a hexagonal hole or a square hole.

Please refer to Figures 2 and 3 for the exploded view of the embodiment (2) and the use of the creation. This embodiment is based on the improvement of the "sleeve and driver combination structure improvement" of No. 102205268. The present invention relates to a sleeve driver comprising: a sleeve 10 and a connecting rod 30, wherein the sleeve 10 comprises: The sleeve body 11 is provided with a sleeve portion 11a and an actuating portion 11b. The center is provided with a through hole 11c extending through the two ends. The sleeve portion 11a is provided with a sleeve hole 11a1. The actuator portion 11b is provided with a polygonal hole 11b1 and a wall. The body is provided with a through hole 11b2; an insert 12 is disposed on the movable bead in the through-cone 11b2; a movable collar 13 is sleeved on the movable portion 11b; a spring 14 The sleeve is disposed between the actuating portion 11b and the movable collar 13 of the sleeve body 11; a retaining ring 15 is a ring-shaped body disposed on the actuating portion 11b of the sleeve body 11 to resist the spring 14; The connecting rod 30 is disposed through the sleeve through hole 11c, and is a polygonal rod body that fits the polygonal hole 11b1 of the actuating portion 11b, and has a joint portion 31 32 at the end thereof and a fitting groove 33 34 at each of the two ends. The improvement includes: at least three magnetic bodies 20 20 ′ are equally disposed on the circumferential surface of the sleeve 11 and the proximal opening of the sleeve 10 20", according to this structure, by the set The magnetic body 20 20' 20" of the hole 11a1 is magnetically stabilized by the workpiece.

The invention relates to a sleeve driver, wherein the polygonal hole 11b1 of the sleeve body actuating portion is a hexagonal or square hole, and the connecting rod 30 is a matched hexagonal or square rod.

The present invention relates to a sleeve driver in which the sleeve hole 11a1 of the sleeve body 11 is a hexagonal hole or a square hole, and the joint portion 31 32 of the connecting rod 30 is matched with an inline bolt head, a cross bolt head or a hexagon socket. The head of the socket.

Please refer to Fig. 3, which is a cross-sectional view showing the improved use state of the sleeve structure of the present invention. The sleeve hole 11a1 can be fitted to the workpiece (bolt head or nut) W during the sleeve operation, and the workpiece W can be magnetically stabilized by the magnetic body 20 20' 20" (not shown) of the sleeve hole 11a1.
