Abstract
The invention relates to a pair of folding wire clippers. The pair of folding wire clippers is composed of tool bits, connection arms and handles. The tool bits and the connection arms are connected with each other through screws. The handles are arranged at the ends of the connection arms. The two tool bits are movably connected together through two clamping plates by means of bolts. The two connection arms are connected with each other through screws. Each connection arm comprises a front connection arm body and a rear connection arm body. The rear connection arm bodies are hinged to the front connection arm bodies. Insertion pins are arranged in the front end faces of the rear connection arm bodies and movably arranged in the rear connection arm bodies. The front ends of the insertion pins extend out of the rear end faces of the rear connection arm bodies. Insertion pin holes matched with the insertion pins are formed in the rear end faces of the front connection arm bodies. The front connection arm bodies and the rear connection arm bodies are locked in a manner of springs and the insertion pins. Automatic inserted connection and locking between the front connection arm bodies and the rear connection arm bodies are achieved through cooperation between the insertion pins and the rear end faces of the front connection arm bodies. The folding wire clippers are simple in structure and convenient to fold.
Description
Technical field
The present invention relates to the technical field of hardware & tools, refer to a kind of bolt clipper especially.
Background technology
Bolt clipper is mainly made up of cutter head, joint arm and handle, and cutter head and joint arm are interconnected by screw, and handle is arranged on the end of joint arm, and two cutter heads are movably connected by bolt by two clamping plate, and two joint arms are also interconnected by screw.Its operation principle is: when needing to shear object, open two handles and joint arm, two cutter heads also and then open, and between cutting edge object being put into two cutter heads, then firmly close, two cutter heads also and then close up, until cut off by reinforcing bar.Due to said structure, although joint arm has certain leverage, can reach labour-saving function, the shearing force that bolt clipper can reach is directly proportional to the length of handle.When actual production, if the length of handle is long, then the inconvenience carried and deposit can be brought.Occurred the folding bolt clipper of a kind of joint arm in the market, solved above-mentioned problem to a certain extent, but the manual operation when folding of its joint arm locks, so operation is more loaded down with trivial details.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of joint arm to fold, and the folding bolt clipper of folding convenient.
For solving the problem, the technical solution used in the present invention is: a kind of folding bolt clipper, by cutter head, joint arm and handle composition, cutter head and joint arm are interconnected by screw, handle is arranged on the end of joint arm, two cutter heads are movably connected by bolt by two clamping plate, two joint arms are also interconnected by screw, joint arm comprises front joint arm and rear joint arm, rear joint arm is hinged in front joint arm, latch is provided with in the front end face of described rear joint arm, latch is movably arranged in rear joint arm, and the front end face of rear joint arm is stretched out in the front end of latch, the pin hole matched with latch is provided with in the rear end face of described front joint arm.
Preferably, be provided with latch chamber in described rear joint arm, latch to be arranged in latch chamber and can to move in latch chamber, spring is provided with in the latch chamber of latch rear end, the sidepiece in latch chamber is provided with driving lever groove, and latch is connected with driving lever, and driving lever is positioned at driving lever groove.
Preferably, the front end of described latch is smooth arc surface.
Preferably, the contact surface of described front joint arm and rear joint arm is inclined-plane, and the front end face of described latch is the inclined-plane corresponding with contact surface.
The invention has the beneficial effects as follows: above-mentioned folding bolt clipper, its locking adopting the mode of spring and latch to realize between front joint arm and rear joint arm, and by coordinating of the rear end face of latch and front joint arm, achieve the autopatching between front joint arm and rear joint arm and locking, structure be simple, folding convenient.

Detailed description of the invention
Fold bolt clipper below by specific embodiment to one of the present invention to be described in further detail.
As Fig. 1, shown in Fig. 3, a kind of folding bolt clipper, by cutter head 1, joint arm and handle 2 form, cutter head 1 and joint arm are interconnected by screw, handle 2 is arranged on the end of joint arm, two cutter heads 1 are movably connected by bolt 4 by two clamping plate 3, two joint arms are also interconnected by screw, joint arm comprises front joint arm 5 and rear joint arm 6, rear joint arm 6 is hinged in front joint arm 5, latch chamber 7 is provided with in described rear joint arm 6, latch 8 to be arranged in latch chamber 7 and can to move in latch chamber 7, spring 9 is provided with in the latch chamber 7 of latch 8 rear end, the sidepiece in latch chamber 7 is provided with driving lever groove 10, latch 8 is connected with driving lever 11, driving lever 11 is positioned at driving lever groove 10, and the front end face of rear joint arm 6 is stretched out in the front end of latch 8, the pin hole 12 matched with latch 8 is provided with in the rear end face of described front joint arm 5.
As a kind of embodiment of the present invention, as shown in Figure 3, the front end of described latch 8 is smooth arc surface.Matched by the back plan of smooth arc surface with front joint arm 5, realize certainly latching of latch 8.Certainly, can be also inclined-plane by the contact surface of described front joint arm 5 and rear joint arm 6, the front end face of described latch 8 be the inclined-plane corresponding with contact surface.Certainly latching of latch 8 is realized by the cooperation on inclined-plane.
Operation principle of the present invention is: as shown in Figure 1, for this folding bolt clipper is in normal operating condition, its front joint arm 5 and rear joint arm 6 are on same straight line, and now latch 8 is positioned at pin hole 12, by the elastic force effect of spring 9, thus realize the locking between front joint arm 5 and rear joint arm 6; After being used to complete, can passing through drawing driving lever 11 backward, latch 8 is moved backward in latch chamber 7, thus realize the unblock between front joint arm 5 and rear joint arm 6, by rotating rear joint arm 6, realize folding, now structure as shown in Figure 2.When needs reuse this folding bolt clipper, only need by the direction bending of rear joint arm 6 joint arm 5 forward, when the front end of latch 8 contacts with the rear end face of front joint arm 5, latch 8 meeting automatic retraction, thus without the need to manually operating, along with the rotation of rear joint arm 6, the front end of latch 8 is inserted smoothly in pin hole 12 and is realized rear locking between joint arm 6 and front joint arm 5.
The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the present invention; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
