Description

Ratchet wheel clyburn spanner

The utility model is a kind of ratchet universal screw wrench, is mainly used in the fastening of various fastenings.

Existing ratchet universal screw wrench (as depicted in figs. 1 and 2), it comprises plate body (1), portable plate mouth (2), button (3), spring (4) and pin (5).Hand push button (3), portable plate mouth (2) clockwise rotate around pin (5), and plate mouth (A) increases gradually, and the nut that varies in size can place in the plate mouth.Unclamp button, by the effect of spring (4), portable plate mouth (2) rotates counterclockwise, and stings jack panel.So just but the moving plate body (1) of up time needle plate has screwed nut.This wrench also can need not take out wrench as ratchet wrench, just can return to rotate counterclockwise and clockwise, is wrenched nut continuously.But the increase of plate mouth (A) and to reduce be limited for example will be pulled smaller specifications of nuts, will use the wrench of small dimension instead.Like this, must be during work with several such wrench.

In view of the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to improve above-mentioned wrench, makes it can pull more specifications of nuts.

Fig. 3,4,5,6 and 7 is the wrench structure charts after improving.

The utility model is achieved in that in the bottom of portable plate mouth (2) two holes (21 and 22), is linked up by a groove (23) between the hole. Pulling body (1) has a hole (12), and the shape in hole is to be made of two garden camber lines (13) and two straight lines (14). The cross sectional shape of pin (5) is identical with the shape of hole (12).

The utility model has the advantages that and enlarged the scope of application.A spanner top 2 is usefulness, and is easy to carry, and the expense that can save the purchase instrument.

For the ease of understanding the utility model, contrast Fig. 6 and 7 pairs of working conditions are further described below.

When pin (5) is in hole (22), pull mouthful engageable bigger specifications of nuts (see figure 6)s if pull smaller specifications of nuts, as long as Flexible spanner mouth (2) is clockwise rotated.When two planes of pin (5) were parallel with groove (23), pin (5) just can enter hole (21) (see figure 7).Flexible spanner mouth (2) is counterclockwise angle of deflection, and plate mouth (A) is with regard to engageable nut.Thereby enlarged the scope of application.
