Embodiment Construction
[0010] The present invention will be described in further detail below in conjunction with the accompanying drawings and preferred embodiments.
[0011] Such as figure 1 , figure 2 As shown, the tin scissors include: a pair of pliers 1 that are staggered and hinged to the first hinged shaft 2. In this embodiment, a pair of pliers 1 are respectively provided with counterbores for installing the first hinged shaft 2. 14. The head 21 at one end of the first hinge shaft 2 and the fastening nut 22 at the other end are respectively supported on the steps in the corresponding counterbore 14. The purpose of opening the counterbore is to shorten the length of the first hinged shaft 2, thereby enhancing the stability of the iron sheet shear. Positioned at the front end of the first hinge shaft 2 is the pliers blade 11, each pliers blade 11 is provided with a cutting edge 111, and positioned at the rear end of the first hinge shaft 2 is the pliers handle 12, each pliers handle Each p...

The invention discloses iron sheet scissors which are very simple and convenient and fast to use. The iron sheet scissors are characterized in that a locking assembly is arranged on a pair of grab handles and can lock cutting edges of cutting portions of scissor bodies to be in a mutually-closed state; and the locking assembly is characterized in that a locking hole is formed in one grab handle, a mounting through hole with a lock shaft and a compression spring is formed in the other grab handle, a circle of groove is formed in the outer wall of the lower end of the lock shaft, and the diameter of the lock hole is larger than that of the lower end of the lock shaft; the upper end of the lock shaft protrudes out of the mounting through hole under the elastic force action of the compression spring, the pair of grab handles are held and pressed to be close to each other till the upper end of the lock shaft is pressed to enable the lower end of the lock shaft to extend into the lock hole, and then the grab handles are released so that the inner side wall of the lock hole can be clamped into the groove in the lock shaft in a blocking manner, so that the pair of cutting edges are always in the mutually-closed locked state; and the grab handles are held and pressed when the cutting edges are in the locked state to enable the grab handles to close to each other continuously so that the lock hole can be disengaged from the groove for unlocking.
Description
technical field [0001] The invention relates to tin scissors among hardware tools. Background technique [0002] A sheet metal scissors is mainly used for cutting sheet metal, iron wire, copper wire and the like. The structure of the traditional tin scissors includes: a pair of pliers arranged in a staggered manner and hinged to the first articulated shaft. The front end of the first articulated shaft is the pliers blade, and each pliers blade is provided with a cutting edge. , located at the rear end of the first hinge shaft is the pliers handle, each pliers handle is hinged with a handle, the head of a pair of handles is located between the two pliers handles, and is hinged on the second hinge An elastic part is clamped between a pair of handles, and the elastic part makes the two handles have a tendency to open outwards, so that a pair of cutting edges have a tendency to open each other, and the two handles are pressed inward to make It closes to each other so that the ...
