[0022] like Figure 1 and Figure 2As shown, a fastener processing tool comprises a base 100, a fixed shell 110 is fixedly connected to the upper side wall of the base 100, a positioning seat 120 is rotatably provided on the upper side wall of the fixing shell 110, four through grooves 130 are provided on the upper side wall of the positioning seat 120, a slider 140 is slidably provided in the through groove 130, a follower block 150 is fixedly connected to the upper side wall of the slider 140, a chuck 160 is detachably connected to the follower block 150 through an assembly component 200, a driving motor 170 is installed on the lower inner wall of the positioning seat 120, a screw 180 is fixedly connected to the output shaft end of the driving motor 170, the upper end of the screw 180 is rotatably connected to the upper inner wall of the positioning seat 120, and a lifting ring 190 is provided on the threaded sleeve of the screw 180 Four connecting rods 191 distributed in a ring array are hinged on the outer circumferential wall of the lifting ring 190, and the other end of the connecting rod 191 is hinged to the bottom wall of the slider 140. A rotating assembly 300 is also provided in the fixed shell 110. When the fastener is positioned, the fastener is placed at the center of the positioning seat 120, and the output shaft of the drive motor 170 can drive the screw 180 to rotate. When the screw 180 rotates, the lifting ring 190 can move downward. During the downward movement, the connecting rod 191 will pull the slider 140, so that the four sliders 140, with the follower block 150 and the chuck 160, approach the fastener at the same time. The chuck 160 clamps the fastener and fixes it. The four-way clamping greatly improves the fixing effect and avoids the fastener from shifting during processing.

[0023] Specifically, such as Figure 4As shown, a fastener processing tool, the assembly component 200 includes an assembly groove 210, a slide groove 220, a clamping block 230, a driving rod 240, a pull plate 250 and a spring 260. An assembly groove 210 is provided on one side wall of the follower block 150 near the center of the positioning seat 120, and two symmetrically distributed slide grooves 220 are provided in the assembly groove 210. A clamping block 230 is slidably provided in the slide groove 220. The clamping block 230 is fixedly connected to the driving rod 240 on a side wall away from the assembly groove 210. The other end of the driving rod 240 extends to the outside of the follower block 150 and is fixedly connected to the pull plate 250. A spring 260 is provided between the clamping block 230 and the side wall of the slide groove 220 away from the assembly groove 210. The spring 260 is sleeved on the driving rod 24 0, when removing the chuck 160, pulling the pull plate 250 can make the driving rod 240 pull the block 230 to retract into the slide groove 220. After losing the obstruction of the block 230, the chuck 160 can be removed. When installing the corresponding chuck 160, the connecting block 161 on the chuck 160 is inserted into the assembly groove 210 on the follower block 150. The connecting block 161 will squeeze the block 230, and the block 230 will retract into the slide groove 220 after being squeezed. When the connecting block 161 is fully inserted into the assembly groove 210, the block 230 loses its squeezing and is inserted into the slot 162 under the push of the spring 260. The connecting block 161 is fixed in the assembly groove 210, and the replacement of the chuck 160 is completed. The replacement method is convenient, fast and more practical.

[0024] Specifically, such as Figure 2 The worm gear 320 is fixed to the bottom wall of the positioning seat 120, and the worm gear 330 is fixed to the bottom wall of the positioning seat 120. The worm gear 320 is fixedly sleeved on the rotatable post 310, and the worm gear 330 is meshed with the worm gear 320 inside the positioning seat 120. One end of the worm gear 330 extends to the outside of the positioning seat 110 and is fixedly connected to the knob 340. During processing, when it is necessary to change the processing direction, the worker rotates the knob 340 to drive the worm gear 330 to rotate. When the worm gear 330 rotates, the worm gear 320 meshed with it drives the rotatable post 310 to rotate. The rotation of the rotatable post 310 drives the positioning seat 120 to rotate, so that the fastener is rotated. The worker does not need to hold the processing tool to change his own position, and can complete multi-directional processing, which is more flexible and practical.

[0025] Specifically, such as Figure 3 As shown, a fastener processing tool is provided, wherein a connecting block 161 is fixedly connected to one side wall of a chuck 160 close to a follower block 150 , and both side walls of the connecting block 161 are provided with a card slot 162 for inserting a card block 230 .

[0026] Specifically, such as Figure 4As shown, a fastener processing tool, the connecting block 161 and the clamping block 230 are wedge-fitted. The wedge-fitting connecting block 161 and the clamping block 230 can allow the clamping block 230 to be squeezed by the connecting block 161 and then retracted into the slide groove 220, making room for the connecting block 161 to enter the assembly groove 210.

[0027] Specifically, such as Figure 1 As shown, a fastener processing tool is provided, wherein the outer circumferential wall of the positioning seat 120 has an extension 121, and the bottom wall of the extension 121 is provided with a plurality of balls, which can provide support for the positioning seat 120, making the positioning seat 120 more stable when rotating.

[0028] When the clamping block 230 is pushed and pushed by the spring 260, the clamping block 230 is inserted into the clamping groove 220, and the clamping block 230 is fixed in the assembly groove 210, and the replacement of the clamping block 160 is completed. The replacement method is convenient and fast, and more practical. When positioning, the fastener is placed on the At the center of the positioning seat 120, the output shaft of the driving motor 170 can drive the screw 180 to rotate. When the screw 180 rotates, the lifting ring 190 can be moved downward. During the downward movement, the connecting rod 191 will pull the slider 140, so that the four sliders 140, with the follower block 150 and the chuck 160, are close to the fastener at the same time. The chuck 160 clamps the fastener and fixes it. The four-way clamping fixation greatly improves the fixing effect and avoids the fastener from shifting during processing. When the processing direction needs to be changed, the worker drives the worm 330 to rotate by turning the knob 340. When the worm 330 rotates, the worm gear 320 engaged with it can drive the rotating column 310 to rotate. The rotation of the rotating column 310 drives the positioning seat 120 to rotate, causing the fastener to rotate, so that the worker does not need to hold the processing tool to change his own position to complete multi-directional processing, which is more flexible and practical.
