[0027] Figures 1-3As shown in the figure, an electric wrench impact sub-head surface treatment equipment, including the body 1 and fixedly connected on the body 1 tool holder 2, tool holder 2 includes fixed seat 202 and slidingly connected with the fixed seat 202 slide 201, there is a gap 9 between the slide 201 and the fixed seat 202 for clamping tool 3, fixed seat 202 and slide 201 are provided with a plurality of adjusting bolts 8, when the adjusting bolt 8 is rotated, the slide 201 slides.

[0028] Figures 1-3 As shown in the figure, so when you need to clamp tool 3, turn the adjusting bolt 8, at this time the slide 201 sliding and the gap 9 becomes larger, so as to facilitate the tool 3 into the gap 9 and adjust the position of the tool 3, when the position adjustment is completed, reverse rotation adjusting bolt 8, at this time the slide 201 slide down and the gap 9 decreases, until the slide 201 and tool 3 form abutment and clamp tool 3.

[0029] Figures 2-4 As shown in the figure, the fixed seat 202 both sides of the wall is slidably connected with the stop block 4, when installing tool 3, the top surface of the stop block 4 and the top surface of the fixed seat 202 are in the same horizontal plane, when the tool 3 is installed, the top surface of the stop block 4 is higher than the top surface of the fixed seat 202, a plurality of slide grooves 6 are formed on the fixed seat 202, and each stop block 4 is fixedly connected with a plurality of sliding blocks 16 located in the slide groove 6 on the side wall close to the fixed seat 202. When the stop block 4 slides, the sliding block 16 slides in the slide groove 6.

[0030] Figures 2-4 As shown in the figure, so after placing the tool 3 in the gap 9 and adjusting the position, slide the stop block 4 upwards, at this time the sliding block 16 slides in the slide groove 6, which plays a role in limiting the sliding range of the stop block 4, until the top surface of the stop block 4 is higher than the top surface of the fixed seat 202, at this time the side wall of the tool 3 is in contact with the inner wall of the stop block 4, and the tool 3 is clamped by further sliding the slide 201, at this time the stop block 4 can effectively limit the activity range of the tool 3, avoiding the left and right deviation of the tool 3 during cutting.

[0031] Figures 2-4 As shown in the figure, the length of the slide groove 6 is less than the thickness of the fixed seat 202, so as to avoid the separation of the sliding block 16 from the slide groove 6 up and down during sliding.

[0032] Figures 2-4 As shown in the figure, the sliding block 16 is a T-shaped block, which can avoid the separation of the sliding block 16 from the slide groove 6 front and back during sliding.

[0033] Figures 2-4 As shown in the figure, two sliding blocks 16 are provided on each baffle, so that the stop block 4 can be uniformly stressed, avoiding the inclination of the stop block 4 during sliding.

[0034] Figures 2-4As shown, the fixed seat 202 and the block 4 are both provided with threaded holes 11, and the threaded holes 11 are threadedly connected with fixing bolts 5 for fixing the block 4. When the top surface of the block 4 is higher than the top surface of the fixed seat 202, the threaded holes 11 on the fixed seat 202 are aligned with the threaded holes 11 on the block 4.

[0035] Figures 2-4 As shown, when the cutter 3 is fixed on the tool seat 2 and the block 4 abuts against one side of the cutter 3, at this time, the block 4 is aligned with the threaded holes 11 on the fixed seat 202, and the fixing bolts 5 are further screwed into the threaded holes 11, so that the block 4 is fixed, thereby avoiding the block 4 from sliding downward to affect the cutting when the cutter 3 is cutting.

[0036] Figures 2-4 As shown, each block 4 is fixedly connected with two blocks 10 extending into the gap 9, and the blocks 10 are perpendicular to the block 4. The fixed seat 202 is provided with grooves 7 corresponding to the blocks 10. When the block 4 slides downward, the blocks 10 slide into the grooves 7.

[0037] Figures 2-4 As shown, by arranging the blocks 10, when the block 4 abuts against the side edge of the cutter 3, the blocks 10 also abut against the bottom surface of the cutter 3, thereby further limiting the movement range of the cutter 3, and avoiding the cutter 3 from gradually penetrating into the gap 9 to affect the cutting precision when the cutter 3 is cutting.

[0038] Figures 2-6 As shown, each groove 7 is provided with two opposite installation grooves 13 on the two side walls, and the installation grooves 13 are slidably connected with closing plates 12 which can abut against each other. When the top surface of the block 4 is higher than the top surface of the fixed seat 202, the two closing plates 12 in the same groove 7 abut against each other and the groove 7 is closed.

[0039] Figures 2-6 As shown, therefore, when the block 4 slides, the blocks 10 also slide into the grooves 7 along with the sliding of the block 4. At this time, due to the pushing of the blocks 10, the closing plates 12 slide into the installation grooves 13, and the groove 7 is opened to facilitate the entry of the blocks 10. After the blocks 10 enter the groove 7, the closing plates 12 are slid out of the installation grooves 13, so that the groove 7 is closed, thereby avoiding the cutting debris from entering the groove 7.

[0040] Figures 2-6 As shown, the installation grooves 13 are fixedly connected with springs 14 between the installation grooves 13 and the closing plates 12. When the closing plates 12 slide into the installation grooves 13, the springs 14 are deformed. Therefore, after the blocks 10 enter the groove 7, the deformed springs 14 push the closing plates 12 to slide, so that the groove 7 is closed. This design plays a role of automatically closing the groove 7.

[0041] Figures 2-6As shown in the drawings, each of the closing plates 12 is provided with a guide slope 15 on the opposite surface, which can facilitate the block 10 to push the closing plate 12 to slide along the guide slope 15.
