When the scissors are used for shearing the carpet nailing strips, the carpet nailing strips are hard, so that large strength is needed to be used, and the scissors are difficult to shear.
Disclosure of Invention
The utility model aims at solving current carpet nailing strip generally because the material is harder, when cuting with ordinary scissors, need use great strength, cut comparatively difficult problem, provide a carpet nailing strip scissors, can effectively solve above-mentioned problem.
The utility model aims at realizing through the following technical scheme: a pair of carpet nailing strip scissors comprises a first cutting part, a second cutting part, a first handle and a second handle, wherein the second cutting part is connected with the second handle; a locking and positioning mechanism is arranged between the second handle and the first shearing part.
The utility model discloses in, articulated formation one each other between first handle, second handle, first shearing part and the connection can play the four-bar linkage of laborsaving effect, through the four-bar linkage, the operator also can obtain great shearing force under the condition of applying less power, can cut the carpet nailing strip comparatively easily, uses comparatively laborsavingly. After the carpet scissors are used up, the carpet nailing strip scissors can be locked in a closed state through the locking and positioning mechanism, on one hand, the phenomenon that the cutting edge on the shearing part is exposed to cause accidental injury can be avoided, and on the other hand, the carpet nailing strip scissors are convenient to store.
Preferably, the second cutout and the second handle are integrally molded.
Preferably, a blade is attached to the first cutting portion.
Preferably, the blade is mounted on the first shearing portion by a set screw. The blade is connected on first shearing part through first fixed screw, the dismantlement and the change of the blade of being convenient for.
Preferably, the locking and positioning mechanism comprises a locking groove formed in the first shearing portion and a sliding portion connected to the second handle in a sliding manner, a sliding boss matched with the locking groove is arranged on the sliding portion, a sliding sheet is connected to the sliding boss, a protruding portion is arranged on the sliding sheet, and two positioning grooves matched with the protruding portion are formed in the second handle. After the carpet nailing strip scissors are used, the carpet nailing strip scissors are in a closed state, and then the sliding bosses are clamped into the locking grooves through the sliding parts, so that the carpet nailing strip scissors are locked in the closed state; when needing to use again, the reverse slip sliding part for the slip boss breaks away from the locking groove, makes the unblock of carpet nailing strip scissors, alright normal use. The sliding sheet has certain elasticity, and the protruding part and the positioning groove on the sliding sheet are mutually matched, so that the sliding boss can be stably stopped at two different positions.
Preferably, the slider is made of metal.
Preferably, the second handle is provided with a guide groove through which the sliding boss passes.
The utility model has the advantages that: the utility model discloses in, articulated formation one each other between first handle, second handle, first shearing part and the connection can play the four-bar linkage of laborsaving effect, through the four-bar linkage, the operator also can obtain great shearing force under the condition of applying less power, can cut the carpet nailing strip comparatively easily, uses comparatively laborsavingly.

Detailed Description
The invention will be further described with reference to the following detailed description and accompanying drawings.
Example 1:
as shown in fig. 1 to 3, the carpet nailing strip scissors comprise a first cutting part 1, a second cutting part 2, a first handle 3 and a second handle 4, wherein the second cutting part 2 is connected with the second handle 4, and the second cutting part 2 and the second handle 4 are integrally formed. One end of the first handle 3 is hinged with the second handle 4 through a second hinge shaft 10, and the first shearing part 1 is hinged with the second handle 4 through a first hinge shaft 9. Be connected with connecting rod 5 between the one end of first shearing portion 1 and the first handle 3, it is articulated through third articulated shaft 11 between the one end of connecting rod 5 and the one end of first shearing portion 1, it is articulated through fourth articulated shaft 12 between the other end of connecting rod 5 and the one end of first handle 3.
