Abstract
The utility model relates to a spanner, particularly a ratchet wheel sleeve spanner. The utility model is composed of a spanner body and a spanner head, wherein a ratchet wheel hole is arranged on the spanner body. The spanner head is composed of a square mallet and a ratchet wheel, wherein the ratchet wheel is arranged in the ratchet wheel hole and ratchets are arranged on the ratchet wheel. Rollers are arranged on the bevels of the ratchets. The upper and the lower ends of the ratchet wheel hole are respectively provided with retainer rings. The rollers and the ratchets are simultaneously contacted with the ratchet wheel hole, and the contact surface can be increased. Thus, the torsion moment in use can be enlarged and the utility model is not easy to slip when used. In addition, the utility model has the advantages of simple structure and simple manufacturing process and the producing cost can be reduced.
Description
Technical field
The utility model relates to a kind of spanner, relates in particular to a kind of box socket set.
Background technology
Existing box spanner generally cooperates the collet head of single size to use with single turret head, thereby need be equipped with multiple different sleeve when the different nuts of dismounting, screw, and this just makes the function of spanner be restricted greatly.In order to address the above problem, Chinese patent (ZL01260262.0) discloses a kind of modular sleeve ratchet spanner, and this spanner comprises wrench body and sleeve, and wrench body is provided with ratchet, and is provided with the non-return sheet of control ratchet rotating.Ratchet inside is provided with polygonal holes, and sleeve is located in the polygonal holes.The patented product complex structure, processing technology is loaded down with trivial details, and when the turn spanner, the non-return sheet is subjected to great active force, skids easily, simultaneously the non-return sheet is damaged easily, has reduced the service life of spanner.
Summary of the invention
In order to solve above-mentioned technical barrier, the purpose of this utility model provides a kind of simple in structure, and processing technology is easy, uses noise little, the sleeve adjustable ratchet wrench that the life-span is long.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of box socket set by pulling body and spanner is formed, is pulled body and is provided with the ratchet hole, and spanner is made up of square vertebra and ratchet, and ratchet is located in the ratchet hole, and ratchet is provided with ratchet, and the inclined-plane of ratchet is provided with roller, and roller can be ball or roller.
The upper/lower terminal in described ratchet hole is respectively equipped with back-up ring.Back-up ring is fixed on the mounting groove on the spanner.As an alternative, mounting groove also can be located on the ratchet hole.
Described side's vertebra is provided with aperture, is provided with spring and spacing steel ball in the aperture.
As preferably, be provided with plastic tube at the angle of cut place of adjacent two ratchets.Can be provided with 2 square vertebras on the spanner.Pull body and be provided with magnet.
In use, handle rotates counterclockwise, and roller upwards moves along the slope of ratchet, closely contacts with the ratchet hole, has blocked and has pulled relatively rotating between body and the spanner.Because what contact with the ratchet hole is roller and ratchet, increased the surface of contact, therefore, also increased the moment of torsion when using greatly, be difficult for during use skidding.The utility model is owing to adopted above technical scheme, and product structure is simple, and processing technology is easy, has reduced production cost.In addition, spanner is provided with 2 square vertebras, when needing backward rotation, pulls body and changes one side and wrench socket is enclosed within to use on another one side's vertebra get final product, uses and conveniently.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.
As Fig. 1, Fig. 2, Fig. 4 and a kind of box socket set shown in Figure 5,, pull body 1 and be provided with ratchet hole 6 by pulling body 1 and spanner 2 is formed, spanner 2 is made up of square vertebra 7 and ratchet 5, ratchet 5 is located in the ratchet hole 7, and ratchet 5 is provided with ratchet 14, and the inclined-plane of ratchet 14 is provided with roller 12.Roller 12 diameters are less than the tooth depth of ratchet 14.Angle of cut place at adjacent two ratchets 14 is provided with plastic tube 13.
The upper/lower terminal in above-mentioned ratchet hole 7 is respectively equipped with plastics back-up ring 4.Plastics back-up ring 4 is fixed on the mounting groove 10 on the spanner 1.The purpose of plastics back-up ring 4 is to prevent that roller 12 and plastic tube 13 from dropping out.
In use, handle rotates counterclockwise, and roller 12 upwards moves along the slope of ratchet 14, closely contacts with ratchet hole 6, has just blocked and has pulled relatively rotating of body 1 and spanner 2.When handle clockwise rotated, roller 12 moved down, and pulled body 1 and spanner 2 can relatively rotate.The purpose of setting up plastic tube 13 is in order to prevent that roller 12 from dropping to the bottom on slope, roller 12 to be lost with ratchet hole 6 contact.
Simultaneously, use for convenience, can be provided with 2 square vertebras 7 on the spanner, square vertebra 7 is provided with aperture 8, is provided with spring 9 and spacing steel ball 11 in the aperture 8.
In addition, the placement of handle is provided with magnet 3 (as shown in Figure 3) in the holding area of pulling body 1 for convenience.
As shown in Figure 6, change the cylindrical roller among the embodiment 1 into ball 15, plastics back-up ring 4 is fixed on the mounting groove 16 in ratchet hole 6 in addition.The other technologies content is as embodiment 1.
