Abstract
The utility model discloses: a quick opening and closing adjustable wrench of a jaw is a tool for screwing a nut. It can overcome the slow not enough of current monkey spanner opening and shutting of keeping silent, the utility model discloses with screw rod (6) that can shift to keep silent rack (7) separation and reunion to make the free or braking of monkey's jaw, consequently obtain the function of opening and shutting the jaw fast.
Description
The utility model is the instrument in order to tightening nuts
Existing spanner alive is that the screw rod (its central shaft of screw rod hollow is a dead axle) of its screw rod rackwork of rotation is regulated width of jaw, and screw rod whenever circles.Jaw moves a pitch distance, and folding speed is slow.
The purpose of this utility model is: a kind of improved governor motion is provided, makes spanner energy quickly opening and closing jaw alive.Thereby increase work efficiency.
The utility model is achieved in that the dead axle screw rod that need not have now on the spanner alive, use movable screw rod instead, be arranged on and can the tooth bar on the jaw of living be carried out on the position of clutch, refill positioner (as spring space) screw stem is positioned on the position of separate or merge.Like this, but constitute a clutch governor motion.When the tooth bar on the lead-screw and the jaw of living broke away from, the jaw of living just can be free to slide, and reaches the purpose of quickly opening and closing jaw.When lead-screw when tooth bar on the jaw of living engages, just recover the function of work spanner.
During tightening nuts, the power that the jaw of living is subjected to can only pass speed along its guide rail (9), and the direction of power is radially vertical with screw rod.Screw rod does not radially stress.So positioner (as the spring space) location that screw stem is firm that can use little moment, and the influence can not removed tight nut the time, and guarantee the portability of lead-screw clutch.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the profile according to the quickly opening and closing jaw that the utility model proposes spanner alive.
Describe the details and the working condition of the utility model concrete structure in detail below in conjunction with Fig. 1.
Embodiment 1:
This spanner two bearings (1), (2) become the identical ellipse garden of length shape blind hole, and (one of them adds closure plate (3) back and forms), central shaft (4) can be radially slided therein, a pair of spring space (5) is respectively adorned in both sides, two bearings hole; This spring space is made up of spring leaf (11) and the bulb projection (12) that is fixed on spring leaf one end, and the other end of spring leaf is fixed on the spanner.Its central shaft of lead-screw (6) (4) but jack-up bulb projection be parked in arbitrary end of long ellipse garden shape dead eye by locator, and located by spring space simultaneously.Near jaw one end is the screw rod and jaw tooth bar (7) bonding station of living, and the other end is a disengaging configuration.Lead-screw just can make the governor motion clutch.For ease of engaging, with the upside one side chamfering (10) of rack tooth.Adorn a retaining at D place and follow closely (8) for the jaw that prevents to live comes off.
Embodiment 2:
Fig. 2, Fig. 3 are the generalized sections (not cuing open in order easily to see eccentric central shaft clearly) of concrete structure and screw rod and the jaw tooth bar clutch state of living of present embodiment:
Central shaft (4 ') is made the eccentric shaft of stage casing off-centre, and screw rod (6 ') is enclosed within on the eccentric position, and the central shaft two ends are sliding joining in the cylindricality dead eye of garden, and lead-screw deflection can be finished screw rod and the clutch of the jaw tooth bar (7 ') of living.Respectively there are two pits to make the usefulness of location on the axial plane at central shaft two ends.Spring (11 ') steel ball (12 ') is formed locator.
Claims (1)
1. the quickly opening and closing jaw spanner of living, feature of the present utility model is: but the governor motion of a screw rod and tooth bar clutch is arranged on this spanner, a movable screw rod (6) wherein is set, place and can carry out on the position of clutch with work jaw tooth bar (7); And two pairs of spring spaces (5) are arranged, device is when the position that is in disengaging when screw rod with the jaw tooth bar of living or engages, on the position that can locate the central shaft (4) of screw rod; This spring space is made up of a spring (11) and a bulb projection (12).
