[0024] Furthermore, a limit slot 205 is provided at the top of the outer wall of the translation seat 200, and a protrusion matching the limit slot 205 is provided at the inner bottom of the bearing seat 206. The limit slot 205 cooperates with the setting of the protrusion so that the movement of the bearing seat 206 on the translation seat 200 can be limited and guided, thereby maintaining the stability of the movement of the bearing seat 206. A plurality of ball grooves 107 are provided at the inner bottom of the rotating seat 101, and auxiliary balls 108 are movably connected to the inner sides of the plurality of ball grooves 107. The auxiliary balls 108 are movably connected to the inner sides of the plurality of ball grooves 107. The outer wall of the swivel seat 101 is movably fitted with the bottom end of the support shaft 102, and the ball groove 107 arranged on the inner side of the rotating seat 101 cooperates with the auxiliary ball 108, which can not only support the support shaft 102, but also reduce the friction resistance between the bottom end of the support shaft 102 and the inner bottom of the rotating seat 101, so that the rotation of the support shaft 102 is smoother. A rotatable driving screw 201 is arranged inside the translation seat 200, and a nut seat 202 is threadedly connected to the outer wall of the driving screw 201. The top of the nut seat 202 passes through the translation seat 2 The linear through groove at the top of 00 is fixedly connected to the inner side of the bearing seat 206. When the driving screw 201 is rotated clockwise or counterclockwise, the nut seat 202 can be driven to move along the outer wall of the driving screw 201. In this way, the movement of the nut seat 202 can drive the bearing seat 206 to move. At the same time, the locking effect between the driving screw 201 and the nut seat 202 can be used to lock the position of the bearing seat 206, so that the knife disc 100 can automatically keep the position fixed after being adjusted to the use position. Make the operation more convenient; one end of the driving screw 201 passes through the outer wall of the translation seat 200 and is fixedly connected to the auxiliary rotating handle 203, the inner side of the translation seat 200 is fixedly connected to the guide rod 204, the outer wall of the guide rod 204 is movably plugged into the round hole opened in the middle of the nut seat 202, the auxiliary rotating handle 203 can improve the labor-saving and convenience of manually driving the driving screw 201 to rotate, and the guide rod 204 can play a limiting and guiding role on the nut seat 202, thereby ensuring the stability of the driving screw 201 driving the nut seat 202.

[0025] In a preferred embodiment, the locking assembly includes a limit rod 104 movably plugged into the side wall of the rotating seat 101, a support seat 106 is fixedly connected to the top of the bearing seat 206, one end of the limit rod 104 passes through the side wall of the support seat 106 and is fixedly connected to a pull handle, an elastic compression spring 105 is fixedly connected between the outer wall of the limit rod 104 and the support seat 106, and the other end of the limit rod 104 can be plugged into the inner side of the positioning groove 103 at the corresponding position. When the locking assembly is used, it is only necessary to manually pull the limit rod 104 outward so that the limit rod 104 drives the elastic compression spring 105 to compress The deformation produces a reverse thrust, so that the end of the limit rod 104 can be pulled out from the corresponding positioning groove 103, and the limiting effect between the rotating seat 101 and the support shaft 102 can be released. In this way, the rotation of the cutter disc 100 can be limited, so that the cutter disc 100 can switch the tool to be used by rotation. After switching to the tool use position, only the tension on the limit rod 104 needs to be released, and the elastic reverse thrust of the elastic compression spring 105 can be used to insert the end of the limit rod 104 into the positioning groove 103 at the corresponding position of the outer wall of the support shaft 102.
