Abstract

The invention discloses a bidirectional utility knife which belongs to manual tools. In the traditional manual tool, a blade is arranged on a knife rest, and the demands on using multiple kinds of blades can hardly be met. The bidirectional utility knife which comprises a knife handle, a knife rest and a pushing and braking assembly, wherein the knife rest is arranged in the knife handle in a sliding manner, the pushing and braking assembly is connected to the knife rest and is exposed out of the knife handle in a protruding manner, two ends of the knife rest are provided with installing parts, each installing part is provided with a blade, two ends of the knife handle are provided with telescopic ports; a first position, a medium position and a second position for positioning the pushingand braking assembly are arranged on the knife handle, when the pushing and braking assembly is positioned on the first position or the second position, one blade arranged on the knife rest extends out of the knife handle and the other blade retracts into the knife handle; and when the pushing and braking assembly is positioned at the medium position, the two blades arranged on the knife rest retract into the knife handle. Two ends of the knife rest can be provided with different kinds of blades, and the blades can be selected according to the demands during using, thus the demands on using multiple kinds of blades are met.

Description

technical field [0001] The invention belongs to hand tools, in particular to a two-way utility knife with blades extending from both ends. Background technique [0002] Existing manual knives that can extend the blade from the handle include a handle, a knife holder, a push assembly, and a blade. The outside of the knife handle is used to push and pull the knife holder to extend the blade on the knife holder out of the knife handle or retract it into the knife handle. But mostly this manual knife is to install a blade on the knife holder, it is difficult to meet the demand of using multiple blades during use. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defect that the existing manual knife installs one blade on the knife holder and it is difficult to meet the needs of using multiple blades, and to provide a two-way utility knife. [0004] In order to solve the above pro...
