In the figure, the cutting tool comprises a blade 1, a blade 2, a connecting arm 3, a pin shaft 4, a folding shaft 5, a folding handle 6, a positioning disc 7, an inner side limiting notch 8, an elastic locking mechanism 9, a locking pin 10, a clamp spring groove 11, a clamp spring 12, a blocking piece 13, a pressure spring 14, an outer side limiting notch 15, a connecting shaft 16, a pressure plate 17, a fixing shaft 18 and a limiting screw.
The specific implementation mode is as follows:
in order to clearly explain the technical features of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings.
As shown in fig. 1-7, a folding handle bolt clipper with locking function, includes two blades 1, the blades 1 are connected with the front end of the yoke 2 respectively, and are connected through the round pin axle 3 between two yoke 2, and the rear end of two yoke 2 is connected with folding handle 5 through folding axle 4 respectively, the rear end of yoke 2 is equipped with positioning disk 6, is equipped with inboard spacing breach 7 on the positioning disk, folding handle front end is equipped with the through-hole, installs elasticity locking mechanical system 8 in the through-hole, and elasticity locking mechanical system 8 and inboard spacing breach 7 cooperation make yoke 2 and folding handle 5 be in coaxial locking state when not receiving external force, and elasticity locking mechanical system 8 breaks away from with inboard spacing breach 7 when pressing elasticity locking mechanical system 8 and realizes folding handle 5's folding.
The elastic locking mechanism 8 comprises a locking pin 9 movably inserted into a through hole at the front end of the folding handle, a thin shaft is arranged in the middle of the locking pin 9, thick shafts are arranged at two ends of the locking pin, the coupling arm is locked with the folding handle when the thick shafts are matched with the inner side limiting notch 7, the coupling arm is unlocked with the folding handle when the thin shafts are matched with the inner side limiting notch 7, a clamp spring groove 10 is formed in one end of the locking pin 9, a clamp spring 11 is installed in the clamp spring groove 10 and used for being clamped with one side of the folding handle, a blocking piece 12 is arranged at the other end of the locking pin 9, and a pressure spring 13 sleeved on the outer side of the locking pin is arranged between the blocking piece 12 and the other side of the folding handle. Under the condition of no external force, the pressure spring 13 is in an elastic extension state, and the coarse shaft is matched and locked with the inner side limiting notch; when the blocking piece 12 is pressed, the pressure spring 13 is compressed, the locking pin 9 generates displacement, when the thin shaft is matched with the inner side limiting notch 7, the edge of the inner side limiting notch 7 cannot block the thin shaft, and the folding handle 5 can rotate at the moment.
Still be equipped with outside spacing breach 14 on the positioning disk 6, when folding handle 5 outwards rotated to outside spacing breach 14, the thick axle can be automatic block and lock in outside spacing breach 14 under pressure spring 13 elastic action, and outside spacing breach 14 is used for realizing the locking after folding handle with the cooperation of elasticity locking mechanical system 8, and its locking is the same with inboard spacing breach principle with the principle of relieving the locking.
