Description

Hand tool drive structure

The present invention relates to a driving tool for a hand tool, and more particularly to a hand tool driving member structure with better applicability and assembly and assembly convenience.

Press, the current hand tool for rotating screws, nuts and other workpieces, in order to have better usability and applicability, there is a kind as shown in the first figure, the second figure and the third figure. The hand tool structure is created. The hand tool includes: a hand tool body 10 and a driving member 20, wherein the hand tool body 10 has a long handle shape, and one end is provided with an assembly hole 101, and the assembly hole 101 is provided with a The unidirectionally rotating ratchet ring 102 has a polygonal hole 103 therein. The driving member 20 has a first end 201 and a second end 202. The first end 201 is provided with a cylindrical portion 203. The cylindrical portion 203 is provided. The outer edge ring is provided with a recess 204 for a C-shaped buckle 205 to be snap-fitted, and the second end 202 is provided with a post 206 for assembling the sleeve, and the first end 201 and the first end A polygonal joint 207 is disposed between the two ends 202. The joint portion 207 can be inserted into the polygonal hole 103 of the hand tool body 10; thereby, the C-shaped buckle 205 of the first end 201 of the driving member 20 is worn. When the corner hole 103 is excessively locked and blocked at the end edge of the polygonal hole 103, the C-shaped buckle 205 is no longer pressed and returns to the natural state. State of a reliable and robust latching, so that the drive member 20 is firmly bonded to the inner polygonal hole 103 of the body 10 of hand tools.

However, in the conventional hand tool structure, the driving member 20 can only be assembled and coupled to the single hand tool body 10 having the polygonal hole 103, and the utility model is not suitable for use, and when the driving member 20 is assembled with the hand tool body 10, First, the cylindrical portion 203 of the driving member 20 is inserted into the polygonal hole 103 of the hand tool body 10. At this time, the C-shaped buckle 205 expands and contracts against the inner edge of the polygonal hole 103, so that the ratchet ring 102 rotates with the driving member 20, thereby causing The joint portion 207 of the subsequent driving member 20 is not easy to be inserted into the polygonal hole 103 of the hand tool body 10, and the assembly and assembly are quite inconvenient, so that it is necessary to improve.

The creator has the disadvantages of poor applicability and inconvenient assembly and assembly, in view of the structure of the hand tool, which is based on the idea of creation and trial, and after several trials and trials, and many corrections and improvements, Launched this creation.

The present invention provides a hand tool driving member structure, the driving member has a polygonal joint portion and a connecting rod connected to the polygonal joint portion, and the polygonal joint portion is provided with a set of connecting holes at an end surface away from one end of the connecting rod. The outer edge of the polygonal joint portion away from the one end of the pole is provided with a circular groove, and the groove is received by a C-shaped buckle. The polygonal joint is provided near the outer edge of one end of the pole. An annular positioning protrusion, the post can be used to assemble a sleeve; thereby, the driving member can be inserted into the polygonal hole of the hand tool body with the polygonal joint thereof, and the driving can be performed The sleeve is inserted into the sleeve of the other hand tool body with its socket hole.

The main purpose of this creation is that the driver can be applied to both hands of the two different structures, and the applicability is improved.

The second purpose of the present invention is that when the driving component is assembled with the hand tool body, the polygonal joint portion of the driving component is directly inserted into the polygonal hole of the hand tool body. Or directly insert the driving member into the socket of the hand tool body with its socket hole, and the assembling and combining action is simple and convenient.

Referring to the fourth figure, the present invention provides a hand tool driving member structure. The driving member 1 has a columnar polygonal joint portion 11 and a connecting rod 12 connected to the polygonal joint portion 11, and the polygonal joint is combined. A square sleeve hole 13 is defined in an end surface of the portion 11 away from the end of the rod 12. The outer edge of the polygonal joint portion 11 away from the end of the rod 12 is provided with a circular groove 14 for a C shape. The buckle 15 is snap-fitted. When the C-shaped buckle 15 is in a natural state, the outer diameter thereof is larger than the opposite side length of the polygonal joint portion 11 of the driving member 10, and a portion of the buckle is protruded outside the groove 14 of the driving member 10. The polygonal joint portion 11 is provided with an annular positioning convex portion 16 near the outer edge of one end of the connecting rod 12. The connecting rod 12 can be used to assemble a sleeve. The utility model 1 has two kinds of hand tool bodies 2, and the first type is provided with an assembly hole 21 at one end, and a ratchet ring 22 capable of unidirectional rotation is disposed in the assembly hole 21. The ratchet ring 22 has a multi-angle hole 23 therein, and the second type is provided with a ratchet driving portion 24 at one end thereof for switching the rotation direction. The ratchet driving portion 24 is provided with a protruding square socket post 25.

When the driving member 1 is combined with the hand tool body 2 of the first structure, as shown in the fifth, sixth and seventh figures, the polygonal joint portion 11 of the driving member 1 is directly aligned and placed in the hand tool. In the polygonal hole 23 of the body 2, the C-shaped buckle 15 disposed at one end of the polygonal joint portion 11 away from the end of the rod 12 passes through the polygonal hole 23, and the C-shaped buckle ring 15 is subjected to the process of passing through the polygonal hole 23 Pressing and shrinking, after passing through the polygonal hole 23, returning to the natural state due to no longer being pressed, the carding stops at the end edge of the polygonal hole 23, and at the same time, the positioning convex portion of the polygonal joint portion 11 disposed near one end of the post 12 is engaged. The portion 16 is fastened to the other end edge of the polygonal hole 23, so that the driving member 1 is firmly coupled into the polygonal hole 23 of the hand tool body 2, and the driving tool 1 is rotated by the hand tool body 2 to cooperate with the driving. The sleeves that are assembled on the post 12 of the member 1 are used to rotate the workpieces such as screws and nuts.

When the driving member 1 is combined with the hand tool body 2 of the second structure, as shown in the eighth and ninth figures, the driving member 1 is directly sleeved by the square socket hole 13 for the square of the hand tool body 2. The post 25 is inserted and locked, so that the driving member 1 is firmly assembled and coupled to the ratchet driving portion 24 of the hand tool body 2, and the driving tool 1 is rotated by the hand tool body 2 to be engaged with the driving member 1 of the post 12. Set the sleeve to rotate the workpiece such as screws and nuts.

From the structure of the above specific embodiment, the following benefits can be obtained:

1. The structure of the hand tool driving component of the invention, the driving component 1 can be simultaneously applied to the hand tool body 2 of two different structures, and the applicability is improved, and the use is more flexible and convenient.

2. The structure of the hand tool driver of the present invention, when the driving member 1 is assembled with the hand tool body 2, the polygonal joint portion 11 of the driving member 1 is directly inserted into the polygonal hole 23 of the hand tool body 2, Or directly insert the driving member 1 into the socket post 25 of the hand tool body 2 with the socket hole 13 thereof, and the assembling and combining action is simple and convenient, and the utility model can be achieved better.

In summary, this creation has indeed reached a breakthrough structure, and has improved content of creation, while at the same time achieving industrial use and progress. When complying with the provisions of the Patent Law, it proposes a new type of patent application according to law. The census review committee granted legal patent rights and was praying.
