Description
Technical field
The utility model belongs to machinery field more particularly to a kind of ratchet spanner easy to process.
Background technology
Ratchet spanner is the tightening tool of a kind of screw or screw etc., can adapt to screw or screw size automatically, go forward side by side
Row clamp operation, specific its are combined by ratchet wrench head and free wrench handle articulated connection, as shown in Figure 1, ratchet spanner
It needs to open up the link slot 3 coordinated with free wrench handle on first 1, link slot 3 generally washes forming by lathe milling, and cost is higher.
But corresponding fixture need to set is washed using lathe milling, and need that ratchet wrench head is manually clamped to fixture one by one
On, efficiency is very slow.In addition ratchet wrench head is also than relatively thin, therefore when milling is washed, and is easy breakage.
Invention content
To solve the above problems, the utility model discloses a kind of ratchet spanneres easy to process.
To achieve the above object, the technical solution of the utility model is：
A kind of ratchet spanner easy to process, including ratchet wrench head and free wrench handle, ratchet wrench head and ratchet wrench
Handle axis connects in succession, and the ratchet wrench head includes top plate, middle plate and lower plywood, and middle plate is shorter than top plate and lower layer
Middle plate is clamped in centre by plate, top plate and lower plywood, and top plate and lower plywood form link slot.
It is further to improve, shaft-jointed hole is formed on the ratchet wrench head and free wrench handle, connecting shaft passes through axis
Hole is connect to connect ratchet wrench head and ratchet spanner arbor.
Further to improve, described free wrench handle one end and ratchet wrench head axis connect, and the other end shapes fluted, groove
It is inside fixed with shaft, shaft is connected with sleeve block, and the interior Hexagonal jacket of different size is formed on sleeve block.
Further to improve, there are four the interior Hexagonal jackets of different size for forming on the sleeve block
Further to improve, the top plate, middle plate and lower plywood are formed with mounting hole, and fixed pin passes through mounting hole
Top plate, middle plate and lower plywood are fixed.
The utility model is simple in structure, easy to use, convenient for punching press or the quickly production of die casting high-volume, reduces and is produced into
This, improves speed of production.
Description of the drawings
Fig. 1 is that existing ratchet spanner decouples structural schematic diagram；
Fig. 2 is the structural schematic diagram of the utility model ratchet wrench head；
Fig. 3 is the partial structural diagram of the utility model free wrench handle；
Fig. 4 is the horizontal cross-section structure diagram of sleeve block.
Specific implementation mode
Below by specific embodiment, and in conjunction with attached drawing, technical scheme of the present invention will be further explained in detail.It answers
Work as understanding, implementation of the invention is not limited to the following examples, the accommodation in any form done to the present invention and/or
Change falls within the scope of the present invention.
Embodiment 1
A kind of ratchet spanner easy to process as in Figure 2-4, including ratchet wrench head 1 and free wrench handle 2, ratchet
Driving end 1 and 2 axis of free wrench handle connect in succession, and the ratchet wrench head 1 includes top plate 11, middle plate 12 and lower plywood 13,
Middle plate 12 is shorter than top plate 11 and lower plywood 13, and middle plate 12 is clamped in centre, and upper layer by top plate 11 and lower plywood 13
Plate 11 and lower plywood 13 form link slot 3.
Shaft-jointed hole 4 is formed on ratchet wrench head 1 and free wrench handle 2, connecting shaft passes through shaft-jointed hole 4 by ratchet spanner
First 1 and 2 axis of free wrench handle connect.
2 one end of free wrench handle and 1 axis of ratchet wrench head connect, other end forming fluted 5, and shaft is fixed in groove 5
6, shaft 6 is connected with sleeve block 7, and the interior Hexagonal jacket 8 of different size is formed on sleeve block 7.
There are four the interior Hexagonal jackets 8 of different size for forming on sleeve block 7.Top plate 11, middle plate 12 and lower plywood 13
It is formed with mounting hole 14, fixed pin fixes top plate 11, middle plate 12 and lower plywood 13 across mounting hole 14.
The form that whole ratchet wrench head is divided into three sheet plates by the utility model assembles, and sheet plate can press
Type casting moulding eliminates the higher milling of cost and washes technique, reduces cost and accelerated the process velocity of ratchet wrench head.In addition
The sleeve block structure of the utility model setting so that it can screw or unscrew the bolt or spiral shell in counterbore of plurality of specifications
Mother etc..
Although the embodiments of the present invention have been disclosed as above, it is not restricted to institute in specification and embodiment
Row use, it can be applied to various fields suitable for the present invention completely, for those skilled in the art, can
Easily realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, this practicality
It is novel to be not limited to specific details and the legend herein shown with description.
