Abstract
The utility model discloses a locking mechanism for manual tools, which comprises a pair of hinged tool heads, torsional springs which are hidden in the tool heads, a handle outside the tool heads, shaft pins of the tool heads, nuts of the shaft pins, etc. The utility model is characterized in that one side of the handle and the shaft pins of the tool heads are in transmission connection and the shaft pins of the tool heads between the other side and the nuts of the shaft pins are provided with locking gears connected by a thread and locking spanners which are meshed with the gears and are provided with handles. The utility model has the advantages of convenient use and labour saving. The handles can be fixed to an angle position which is open freely, which is convenient for using the handles as single arm rotary tools or tools. The handles on the locking spanners can be ensured to be in a better initial position to make manual tools have beautiful appearance and convenient operation.
Description
The utility model relates to the retaining mechanism of hand-held tool opening angles such as instrument, scissors.
Hand-held tool comprises instrument, scissors etc., in plant produced, all be unable to do without these hand-held tools in repair work and the daily life, and these hand-held tools much all are multifunction combined, it has brought convenience for people's work and life, " convertible two instrument " as the patent No. 99203021.8, it is except two instrument ports of the turning use in two that had, on its handgrip, be provided with respectively and revolve tool storage tank and instrument storage tank, these storage tanks are provided with various tool and the small tools of revolving for a short time, take out during use revolve for a short time tool or small tool toward handgrip afterbody one insert constitute the band handgrip revolve tool or instrument, and when using these to revolve tool or instrument separately, in order to increase torque, two handgrips must be a suitable angle, if there is not retaining mechanism this moment, the open angle of two handgrips just can't keep, convenience and effect that influence is used, for this reason, " convertible two instrument " designed latching device, snap close with driven mode pins jaw, and this method is used inconvenient, and effect is undesirable.
The purpose of this utility model all provide in the defective that overcomes prior art a kind of easy to use, laborsaving, locking effect is comparatively ideal and the operating portion potential energy is determined the hand-held tool retaining mechanism of initial position.
Embodiment of the present utility model is: its design is when two handgrips need be locked in the opening angle position, allow a handgrip maintain static, and another handgrip impels by the frictional force that clamping force produced and fits tightly between the handgrip and can't rotate mutually, promptly is locked on the angle position.This retaining mechanism comprise a pair of by the hinged tool heads of tubular rivet, be built in the torsion spring in the inboard symmetrical channels of two tool heads, the outer handgrip movable set of tool heads is passing on the tool heads pivot pin of tubular rivet, and piece together tight by the pivot pin nut, it is characterized in that described handgrip one side and tool heads pivot pin are in transmission connection, opposite side and tool heads pivot pin between the pivot pin nut be provided with the locking gear that is threaded and with the locking spanner of the band handle of its engagement.
The advantage of this retaining mechanism is to use convenience, laborsaving, the handle of hand one trip lock spanner, engagement by inside and outside tooth produces enough big moment of torsion, club hand is locked on any angular position of requirement being stuck, locking effect is fine, and handgrip just can revolve tool or instrument use as single armed, adopts the purpose of inside and outside tooth, can guarantee to lock on the spanner being in initial position preferably, make hand-held tool have good looking appearance and be convenient to the operation.
Description of drawings:
Fig. 1 is the utility model structure cross-sectional schematic.
Fig. 2 is a tool heads pivot pin structure chart.
Fig. 3 is locking spanner structure figure.
Fig. 4 is the vertical view cutaway drawing of Fig. 3.
Below with reference to above-mentioned accompanying drawing the utility model is described in detail again.
Hand-held tool retaining mechanism (referring to Fig. 1-4) comprises a pair of tool heads (3) that is linked to each other by tubular rivet hinged (8), and tool heads can be pliers or scissors.Below just be that example makes a presentation with the pliers, pliers can be a double-headed pliers, one is nippers, the other end is a round nose pliers, the turning use in two.The open torsion spring of jaw elasticity (7) is built in the inboard symmetrical channels of two binding clips, and the inside and outside handgrip (2) that is the shaped as frame structure clads outside binding clip relatively, and movable set is passing on the tool heads pivot pin (1) of tubular rivet, and is pieced together tight by pivot pin nut (5).For binding clip opening angle position is locked, be provided with retaining mechanism, promptly make and be in transmission connection at external handlebar one side and tool heads pivot pin, as long as the tool heads pivot pin does not rotate, external handlebar promptly is fixed motionless.The opposite side of inside and outside handgrip and tool heads pivot pin between the pivot pin nut be provided with the locking gear (6) that is threaded and with the intermeshing band handle of the locking gear locking spanner (4) of (11).
Handgrip one side can be connected by the side's of being tenon (9) with being in transmission connection of tool heads pivot pin, and its side's tenon length of side is equal to or greater than tool heads pivot pin round bar portion (10) diameter, and present embodiment adopts the length of side to equal the square feather joint of tool heads pivot pin round bar portion diameter.Also can be that profile of tooth connects, its profile of tooth internal diameter be equal to or greater than tool heads pivot pin round bar portion diameter.Can also be that polygon connects, its polygon inscribed circle diameter be equal to or greater than tool heads pivot pin round bar portion diameter.
The utility model closes up and two handgrips open when needing it to be locked in an angle position at two jaws, buttress a handgrip on the other hand, as long as another hand is pulled the handle of locking spanner, locking spanner transmitting torque is in locking gear, and the rotation of locking gear makes the tool heads pivot pin overhanging and make the part that is sleeved on the tool heads pivot pin be subjected to the effect of frictional force and tightly be locked in a position.The handle of locking spanner can be located at an initial position according to the shape facility of hand-held tool arbitrarily, is convenient to the purpose of operating again to reach the hand-held tool good looking appearance.
