Description

Sleeve tool

The present invention relates to a sleeve tool, and more particularly to a sleeve tool that provides a tool joint in either a fixed or a rotating form and that automatically returns the tool joint to an unadjusted front angle.

Please refer to the sleeve tool shown in Figures 1 and 2, which is a sleeve post 1 of a fixed tool joint commonly used in the industry, one end of which is a workpiece joint 11 for disassembling or locking screws, and different One end of the workpiece joint 11 is a tool joint 12, and one end of the tool joint 12 is fixed in the sleeve post 1 and is sleeved on the tool joint 12 by a manual or electric tool to drive the sleeve post. The rotation of 1 achieves the function of disassembling or locking the screw, but when the screw is located in a relatively narrow space, the tool joint 12 cannot be adjusted to the angle between the sleeve and the socket 1 because of the fixed type, so that the manual or electric The tool cannot be inserted, and the sleeve post 1 cannot be driven, thereby affecting the work efficiency. Therefore, the sleeve post 2 of the rotatable tool joint is produced as shown in the third to fifth figures to provide different occasions. The sleeve pin 2 of the angle can be adjusted, one end of which is a workpiece joint 21 for disassembling or locking the screw, and one end of the workpiece joint 21 is a tool joint 22, and one end of the tool joint 22 is provided with a ball swinging member. 23, the ball swinging member 23 can be sleeved into the sleeve In the rod 2, a uniform through hole 231 is defined in the ball swinging member 23, and a shaft 24 can be passed through the through hole 25 of the sleeve post 2 and the through hole 231 of the ball swinging member 23, so that the ball swinging member The 23 pivot limit is located at the sleeve post 2, so that the ball swinging member 23 can be centered on the shaft 24 as needed. Adjust the angle. In this way, the angle of the tool joint 22 can be adjusted according to the requirements to achieve the function of disassembling or locking the screw. However, when the work is completed, the ball swinging member 23 cannot automatically return to the original position, and the user needs to use the hand. Pull it back and return the sleeve post 2 to its unadjusted angle, so as to facilitate storage. Therefore, each time the angle is adjusted, it needs to be manually returned once to the original unadjusted angle, which causes invisible use. And the troubles in storage.

Therefore, the inventor of the present invention has many years of experience in the design and manufacture of various hardware tools, especially the ink of the wrench and the sleeve tool. In view of the inconvenience of the existing sleeve post, it is possible to provide a fixing. The sleeves of the tool joints of the two types of use or the rotary type are actively researched and improved, and the invention is produced.

The main object of the present invention is to provide a sleeve tool in which the tool joint is in a fixed or rotary form by means of limiting and releasing between the adjusting seat and the positioning block.

Another object of the present invention is to provide a sleeve tool which can automatically return to the unadjusted front angle after the external force is removed by the elastic member and the positioning block.

In order to achieve the above purpose, the sleeve tool of the present invention mainly uses one end of a sleeve post as a workpiece joint for disassembling or locking a screw, and one end of the workpiece joint is a set of joints. The inner portion of the segment is a shaft hole, and the sleeve portion is respectively provided with a through hole penetrating the sleeve portion, a limit hole for the limit ball sleeve, and a limit groove for setting a C-shaped buckle ring. The tool joint set is sleeved in the shaft hole of the sleeve section of the sleeve post, and mainly comprises an elastic component, a positioning block and a tool joint which are sequentially sleeved in the shaft hole, and the positioning block is The first end face is subjected to an elastic element The top of the positioning block is provided with an annular positioning groove, the positioning groove is located at the bottom end of the limiting ball, and the second end surface of the positioning block can be abutted against the tool joint, the tool joint end a ball oscillating member, the ball oscillating member has an abutting surface extending at one end thereof, the abutting surface abutting against the second end surface of the positioning block, and the ball oscillating member is provided with a permanent perforation, the through hole is for one axis The rod is penetrated by the through hole of the sleeve segment and penetrates the through hole, so that the ball swinging member is pivotally limited to the sleeve portion; an adjustment seat sleeve is limited to the outer diameter of the sleeve portion and is located The upper side of the limiting ball is horizontally displaced from the left and right sides of the sleeve. The adjusting seat is respectively provided with a positioning section and a releasing section, wherein the inner diameter of the positioning section is smaller than the inner diameter of the releasing section.

The advantages of this sleeve tool are:

(1) The sleeve tool of the tool joint can be provided in fixed or rotary form by the limitation and release between the adjusting seat and the positioning block.

(2) With the elastic element and the positioning block, the tool joint after adjusting the angle can automatically return to the unadjusted angle after the external force disappears, and the convenient sleeve tool for the following use and storage can be utilized.

The limiting hole 323 can be sleeved by a limiting ball 325. A C-shaped buckle 326 is disposed on the groove 324; a tool joint set 4 is mainly sleeved in the shaft hole 321 of the sleeve portion 32 of the sleeve post 3, and the tool joint set 4 includes an elastic member 41, a positioning block 42 and a tool joint 43, and an elastic member 41, a positioning block 42 and a tool joint 43 are sequentially sleeved in the shaft hole 321 , and the positioning block 42 is The first end surface 421 is abutted against the end of the elastic member 41. The proximal portion of the positioning block 42 is provided with an annular positioning groove 422, which is located at the bottom end of the limiting ball 325. The second end surface 423 of the positioning block 42 can be abutted against the tool joint 43 , and one end of the tool joint 43 is a ball swinging member 431 , and the ball swinging member 431 is extended at one end. An abutting surface 432 is formed. The abutting surface 432 can abut against the second end surface 423 of the positioning block 42. The spherical rocking member 431 is provided with a permanent through hole 433. The through hole 433 can be provided by a shaft 434. The through hole 322 of the sleeve portion 32 is bored and penetrates the through hole 433, so that the ball swinging member 431 is pivotally limited to the sleeve portion 32; and an adjusting seat 5 is sleeved in the sleeve The outer diameter of the splicing portion 32 is located above the limiting ball 325, and can be laterally displaced laterally on the splicing portion 32. The positioning portion 51 is respectively provided with a positioning portion 51 and a releasing portion 52, wherein the positioning portion The inner diameter of the segment 51 is smaller than the inner diameter of the relief section 52.

If so, the sleeve 5 is limited to the outer diameter of the sleeve portion 32 and is located above the limit ball 325, and the elastic member 41, the positioning block 42 and the tool joint 43 are sequentially sleeved on the shaft. In the hole 321 , the first end surface 421 of the positioning block 42 is abutted against the first end surface 421 of the positioning block 42 , and the positioning groove 422 of the positioning block 42 is located at the bottom end of the limiting ball 325 , and the positioning block 42 is located.
