Abstract
The utility model relates to an auxiliary spring of a folding knife. The auxiliary spring comprises a blade, a base frame, a lining plate A, a lining plate B, an auxiliary spring body, a spacing sleeve and a rotary shaft. The auxiliary spring is characterized in that the auxiliary spring body (5) is arc-shaped, a flat contact surface (15) is arranged at one end of the auxiliary spring body (5), and a spring groove (16) is formed in the base frame (2) to fix the contact surface (15) of the auxiliary spring body (5). Compared with the prior art, the auxiliary spring of the folding knife has the advantages of being simple in structure, easy to manufacture and install, and capable of making the folding knife opened fast in a time-saving and labor-saving mode.
Description
Technical field
The utility model belongs to jack knife, especially a kind of power assistant spring of jack knife.
Background technology
When existing jack knife is opened, waste time and energy, close adhesive poor performance, easily meet accident, safe not.
Summary of the invention
The purpose of this utility model is to address the above problem, provide a kind of simple in structure, time saving and energy saving, be easy to the power assistant spring of jack knife manufacturing and install.
As follows for reaching the technical solution that above-mentioned object takes:
1, a kind of power assistant spring of jack knife, comprise blade, end bone, liner plate A, liner plate B, power assistant spring, spacer sleeve, rotating shaft, it is characterized in that, described power assistant spring is made as arc, one end is provided with flat contact-making surface, and described end bone is provided with the contact-making surface of the fixing power assistant spring of spring groove.
2, the power assistant spring of the jack knife as described in technical scheme 1, wherein, described spacer sleeve is respectively through the axis hole of liner plate A, end bone, liner plate B, and fixes with liner plate screw.
3, the power assistant spring of the jack knife as described in technical scheme 1, wherein, described rotating shaft is through the axis hole of liner plate A, blade and liner plate B, and fixes with rotating shaft screw.
Compared with prior art, advantage is simple in structure to the utility model, is easy to manufacture and install, and has fast and opens, time saving and energy saving feature.

In Fig. 1～10, blade (1), end bone (2), liner plate A(3), liner plate B(4), power assistant spring (5), rotating shaft (6), pull nail (7), stop bit nail (8), spacer sleeve (9), rotating shaft screw (10), liner plate screw (11), axis hole (12), steel ball hole (13), cambered surface (14), contact-making surface (15), spring groove (16), axis hole (17), interval trepanning (18), stop bit nail hole (19), steel ball hole (20).
the specific embodiment:
Below in conjunction with drawings and Examples, the utility model is further described:
As shown in Figures 1 to 8, a kind of power assistant spring of jack knife, comprise blade, end bone, liner plate A, liner plate B, power assistant spring, spacer sleeve, rotating shaft, wherein, described power assistant spring 5 is made as arc, one end is provided with flat contact-making surface 15, and described end bone 2 is provided with the contact-making surface 15 of spring groove 16 fixing power assistant spring 5.Described spacer sleeve 9 passes respectively liner plate A3, end bone 2, the axis hole 12 of liner plate B4, axis hole 17, and fixing with liner plate screw 11; The axis hole of liner plate A3, blade 1 and liner plate B4 is passed in described rotating shaft 6, and fixing with rotating shaft screw 10.
Embodiment as shown in Figure 8, when blade 1 is when opening, power assistant spring does not produce elastic force.
Embodiment as shown in Figure 9, blade 1 is in open mode in closing process, and when blade 1 forwards a half of about stroke to, power assistant spring 3 contacts and produces elastic force with the lock face of blade 1, and along with blade 1 is rotated further and strengthens elastic force; When blade 1 will enter buttoned-up status, power assistant spring 3 contacts with the cambered surface 14 of blade 1, and power assistant spring 3 and blade 1 active force that do not rotate, until the steel ball lock ledger-plate 1 on liner plate A3; Pull mutually, promote pulling of blade 1 and follow closely 7, blade 1 blade release is also rotated further, and the elastic force of power assistant spring 5 starts to discharge, and due to the effect of elastic force and inertia, blade 1 accelerates to rotate, and to reach full open position, the shell fragment of liner plate A3 locks blade 1.
The feature and benefit that this specific embodiment has: there is the feature of opening fast, time saving and energy saving, be conducive to blade locking, simple in structure, be easy to manufacture and install.
