Accompanying drawing explanation
Fig. 1 is the structural representation of tinsmith snips described in the utility model.
Fig. 2 is the sectional structure schematic diagram that Fig. 1 looks up the installation through hole in direction.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, tinsmith snips, comprise: being crisscross arranged and being hinged is connected to a pair caliper 1 of the first jointed shaft 2, the head 21 of counterbore 14, first jointed shaft 2 one end and the clamp nut 22 of the other end in the present embodiment, a pair caliper 1 offered respectively for installing the first jointed shaft 2 is bearing on the step in corresponding counterbore 14 respectively.The object offering counterbore is: the length shortening the first jointed shaft 2, thus strengthens the stability of tinsmith snips shearing.What be positioned at the first jointed shaft 2 front end is caliper blade 11, each caliper blade 11 is provided with cutting edge 111, what be positioned at the first jointed shaft 2 rear end is caliper shank 12, each caliper shank 12 is all hinged by bearing pin 121 and is connected to lever 3, in order to strengthen curable grip, lever 3 also can be set with and hold cover with anti-slip veins.The head of a pair lever 3 is between two caliper shanks 12, and be hinged in the second jointed shaft 4, elastomeric element is arranged with between a pair lever 3, elastomeric element makes two levers 3 have outwardly trend, thus make a pair cutting edge 111 have the trend mutually opened, the present embodiment Elastic parts are torsion spring, on the second jointed shaft 4 between the head that described torsion spring is arranged on a pair lever 3, the two ends difference block of torsion spring is in the inner side of a pair lever 3, torsion spring makes two levers 3 have outwardly trend, thus make a pair cutting edge 111 have the trend mutually opened.Inside grip pressure two levers 3 make it mutually draw close to make the cutting edge 111 of a pair caliper blade 11 mutually closed thus shear, described a pair lever 3 is provided with the latch assembly that the cutting edge 111 of caliper blade 11 can be made to be locked at mutual closure state, latch assembly comprises: on a lever 3, be provided with lockhole 5, another lever is provided with through hole 6 is installed, install in through hole 6 and be provided with lock shaft 7, the outer wall of lock shaft 7 bottom is provided with a circle and lockhole 5 with the use of groove 8, the diameter of lockhole 5 is greater than the diameter of lock shaft 7 bottom, install and the lock shaft 7 in through hole 6 is set with by pressing spring 9, be fastened on lock shaft 7 by pressing spring 9 and install between through hole 6, the upper end of lock shaft 7 protrudes from and installs through hole 6 under by the elastic force effect of pressing spring 9, grip pressure a pair lever 3 makes it mutually draw close until lock shaft 7 is aimed at mutually with lockhole 5, then the upper end pressing lock shaft 7 makes the bottom of lock shaft 7 stretch in lockhole 5, because under the elastic force effect of torsion spring, a pair lever 3 has outwardly trend, therefore unclamping lever 3 can make in the groove 8 of the madial wall block of lockhole 5 on lock shaft 7, thus make the cutting edge 111 of a pair caliper blade 11 be in mutually closed state, when locking state removed by needs, grip pressure cutting edge 111 is in locking a pair lever 3 in closed state, makes the madial wall of lockhole 5 depart from groove 8, now under the effect of pressing pressing spring 9, lock shaft 7 outwards ejects and makes groove 8 leave lockhole 5, thus lockhole 5 and groove 8 can be made to be separated and to remove locking, installation through hole 6 under releasing locking state and lock ring hole without mutual interference, thus ensure that normal shearing work.The operation that the locking of above-mentioned cutting edge 111 and releasing are locked is all very simple and reliable, convenient.
