Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic scissors, in particular to a novel pneumatic scissors. Background Art

[0002] After retrieval, application number 202021547434.0 discloses a hawk-beak type pneumatic scissors, including a tool holder, an upper blade of scissors, a lower blade of scissors and a cylinder push rod. The upper blade of scissors and the lower blade of scissors are cross-arranged and rotatably connected at the intersection. The handle of the upper blade of the scissors is located below the intersection and is the lower handle. The handle of the lower blade of the scissors is located above the intersection and is the upper handle. The telescopic end of the cylinder push rod is connected to the end of the lower handle.

[0003] During use, the eagle-beak type pneumatic scissors in this patent application use the cylinder push rod to push the upper handle and the lower handle to slide forward along the corresponding slide. Since the two slides intersect, the upper blade and the lower blade of the scissors close together for shearing during the forward sliding process. However, during such use, since the upper blade and the lower blade of the scissors of the device are moving while closing for shearing, the shearing position of the device is constantly changing, which can easily cause the shearing position of the material to shift and affect the processing quality. For this reason, we propose a new type of pneumatic scissors. Utility Model Content

[0006] Furthermore, a blade fixing screw is provided at the rear end of the action blade and is threadedly mounted on the left rear side of the horizontal end of the fixing bracket.

[0007] Furthermore, the bottom end of the gasket 1 abuts against the middle of the top wall surface of the blade screw shaft.

[0008] Furthermore, the top of the second gasket abuts against the bottom end of the self-locking nut.

[0009] Furthermore, a clearance through hole corresponding to the telescopic end of the cylinder is opened through the middle of the right wall surface of the vertical end of the fixing bracket.

[0010] Furthermore, a bracket fixing screw threadedly mounted with the right end of the cylinder is provided at the edge of the right wall surface of the vertical end of the fixing bracket.

[0011] Furthermore, the driving block is L-shaped.

[0012] Furthermore, the telescopic end of the cylinder is fixedly mounted on the right wall surface of the vertical end of the driving block.

[0013] Furthermore, the driving screw shaft is in a vertical state and is threadedly connected to the horizontal end of the driving block.

[0016] Beneficial Effects

[0017] The utility model provides a new type of pneumatic scissors, which has the following beneficial effects:

[0018] 1. This novel pneumatic scissors is provided with a driving mechanism. When in use, the device is fixedly installed at a designated position through a fixed bracket. When a shearing operation is required, the telescopic end of the cylinder is controlled to contract to drive the driving block to move to the left, and the driving block drives the driving screw shaft to move to the left and squeezes the inner wall of the linear slide groove on the rear end of the blade screw shaft, forcing the rear end of the blade screw shaft to rotate to the left with the fixed blade as the axis, thereby driving the front end of the blade screw shaft to rotate to the right and close to the front end of the action blade to complete the shearing operation, and then controlling the telescopic end of the cylinder to extend to drive the blade screw shaft to rotate and reset. The above operation is simple and practical, and the structure is reasonable and compact, so that the shearing position of the device remains unchanged, thereby improving the processing quality of the material by the device, and the connection method between the various components of the device is simple and convenient, which is convenient for the staff to install and disassemble the device and perform subsequent maintenance operations.

[0019] 2. This new type of pneumatic scissors is equipped with a self-locking mechanism. Since the self-locking nut limits the top of the compression spring through the gasket 2, the gasket 1 pushes the blade screw shaft and the action blade to always maintain a close fit under the elastic force of the compression spring, so that the blade screw shaft can better cooperate with the action blade to shear the material, thereby improving the practicability of the equipment.
