Abstract
The invention discloses a wrench which comprises a handle, a fixed jaw and a movable jaw, wherein the fixed jaw is located at one end of the handle, the movable jaw is movably connected to the handle and opposite to the fixed jaw, a shifting rod is arranged on the handle, straight teeth are arranged on the shifting rod, straight teeth are arranged on the movable jaw, the movable jaw and the shifting rod are connected through a straight gear, and the straight gear is located inside the handle. According to the wrench, the position of the movable jaw can be adjusted by pushing the shifting rod, and then adjustment of the opening degree of the wrench is achieved. Shifting rod adjustment has the advantages of being high in practicality and convenient to use. By the adoption of the wrench, working efficiency can be greatly improved.
Description
Technical field
The present invention relates to a kind of spanner.
Background technology
The moving jaw position of existing spanner all regulates by being located at the borded pile of one end of handle, and such spanner exists awkward defect.When conventionally working, need to twist borded pile, the moving jaw that makes to be movably arranged on handle is done straight-line displacement, regulates thus the position of moving jaw, makes the distance of determining between jaw and moving jaw adapt to need of work.
Summary of the invention
The technical problem to be solved in the present invention is to provide moving jaw and regulates spanner easily.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: this spanner comprises handle, determines jaw and moving jaw, describedly determine one end that jaw is positioned at handle, described moving jaw be movably connected on handle and with determine jaw in relative position, described handle is provided with driving lever, and described driving lever is provided with straight-tooth, and described moving jaw is provided with straight-tooth, between described moving jaw and driving lever, by spur gear, be connected, described spur gear is positioned at handle inside.
For the adjustable range that allows driving lever reach is enough large, as of the present invention preferably, this end diameter that spur gear is connected with driving lever is less than the diameter of this end that spur gear is connected with moving jaw.The displacement of driving lever is amplified after the leverage of spur gear like this, makes the moving jaw can grand movement.
For making the operation of driving lever light and handy, preferably described spur gear is trapezium structure as of the present invention, and this end diameter that spur gear is connected with driving lever is greater than the diameter of this end that spur gear is connected with moving jaw.So only need the less moving driving lever of trying hard to recommend, thereby make the adjustment operation of moving jaw more convenient.
Because the muscle power of spanner is less, in order to make driving lever be combined on handle, as of the present invention preferred, described driving lever is platy structure.Between driving lever and handle, by the mode embedding, be combined on handle, driving lever both sides are limited by handle, and expose on handle top driving lever middle part, thus can so that external thrust act on driving lever.
The present invention adopts technique scheme: this spanner is the position of adjustable moving jaw by promoting the mode of driving lever, then realize the adjustment operation of the jaw size of spanner, driving lever adjusting has advantages of practical, easy to use, and the use of this spanner can greatly be increased work efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further described in detail.
Fig. 1 is the structural representation of a kind of spanner of the present invention.
the specific embodiment
As shown in Figure 1, this spanner is provided with the handle 1 of rectangular and flat, is provided with one determines jaw 3 and a moving jaw 2 in one end of handle 1, determines jaw 3 and is connected as a single entity with handle 1, and moving jaw 2 is movably arranged on handle 1.One end of moving jaw 2 is provided with the rounded projection of cross section, and the thickness of this boss is greater than the thickness at moving jaw 2 other positions, and moving jaw 2 is provided with straight-tooth at this boss.Handle 1 is provided with the groove of shape of the cross section of corresponding moving jaw 2, and the cross section of this groove is identical with the shape of the cross section of moving jaw 2.Moving jaw 2 is embedded in groove, makes the moving jaw 2 can only be movable along groove, and slides in groove afterwards it and the position relationship determined between jaw 3 of moving jaw 2 changes.Owing to determining jaw 3, be positioned on the bearing of trend of groove, make to determine jaw 3 with moving jaw 2 in relative position relationship.
During use, stir driving lever 4, driving lever 4 is moved along handle 1, straight-tooth engagement on straight-tooth on driving lever 4 and spur gear 5, spur gear 5 rotates thus, and then spur gear 5 drives moving jaws 2 motions, and moving jaw 2 and the distance of determining between jaw 3 are adjusted thus.
The another kind of embodiment of the present invention, this example and the difference of above-described embodiment are that this end diameter that spur gear is connected with driving lever is greater than the diameter of this end that spur gear is connected with moving jaw, by ordering about moving jaw by driving lever, move, but it is smaller now to stir the required power of driving lever, this is because the arm of force forming between spur gear and driving lever is greater than the arm of force forming between moving jaw and spur gear.
Claims (4)
