[0002] Tool scissors usually refer to a kind of manual tool for cutting materials, which are widely used in families, factories and various industrial occasions. According to the types of materials cut and their uses, tool scissors can be divided into ordinary scissors, metal scissors, electric scissors, and gardening scissors. When selecting tool scissors, it is necessary to consider that high-quality steel or stainless steel can improve durability and cutting effect, and an ergonomic design can reduce hand fatigue, and select the appropriate type of scissors according to actual needs.

[0003] In the current cutting process, the appropriate tool scissors are usually selected according to specific needs. However, traditional tool scissors often require manual pinching for cutting processing, which is not only time-consuming and laborious, but also has certain requirements for the technical level of operators. Since the thickness and hardness of different items vary, operators need to frequently replace the corresponding scissors to ensure the cutting effect. This situation not only reduces the cutting efficiency but also affects the convenience of work. For this reason, we propose a portable hydraulic tool scissor. Content of the Utility Model

[0023] The present utility model provides a technical solution: As Figures 1 - 5As shown in the figure, in this embodiment, a portable hydraulic tool shear includes a cavity 1.

A chute 11 is opened at one end of the mounting block 4. A second push-pull rod 25 is fixedly connected to one side of the second piston 22. One end of the second push-pull rod 25 extends into the chute 11. The extended end of the second push-pull rod 25 is fixedly connected to a moving block 16.
