First chutes 3 are arranged on the upper parts on both sides of the crushing body 1, a first slider 4 is slidably installed inside the first chute 3, a connecting rod 5 is fixedly connected to one side of the first slider 4, and between the two connecting rods 5 and above the crushing body 1, a handle 6 is fixedly connected. The bottom of the handle 6 penetrates into the two connecting sleeves 2. On both sides of the top and bottom of the inner cavity of the connecting sleeve 2, first spring shock absorbers 7 are fixedly connected, one end of the first spring shock absorber 7 is fixedly connected to the surface of the handle 6, and an elastic buffer pad 8 that cooperates with the connecting sleeve 2 is installed on the surface of the bottom of the handle 6. An adjustable side grip assembly 9 is fixedly connected to the surface of the crushing body 1. The elastic buffer pad 8 is made of rubber.

[0024] The adjustable side grip assembly 9 includes a side grip connection box 10, a grip 11, and a bolt 12. The side grip connection box 10 is installed on the front surface of the crushing body 1. A connection frame 13 is slidably installed inside the side grip connection box 10. A second sliding groove 14 is formed at the rear part of the inner cavity of the side grip connection box 10. A second sliding block 15 is slidably installed inside the second sliding groove 14. The rear part of the connection frame 13 is fixedly connected to the second sliding block 15 through a connecting member. A first long groove 16 for cooperating with the grip 11 is formed on the front surface of the side grip connection box 10. The front side of the connection frame 13 is fixedly connected to the grip 11 through a connecting member. The grip 11 penetrates through the side grip connection box 10 and extends to the outside of the side grip connection box 10. Only the front end of the bolt 12 has threads for cooperating with the threaded hole 24, and the rest of the part has no threads.

[0025] Inner sliding grooves 17 are formed at both the front and rear parts of the inner cavity of the connection frame 13. Third sliding blocks 18 are slidably installed inside the inner sliding grooves 17. A cross plate 19 is fixedly connected between the two third sliding blocks 18 through a connecting member. Second spring shock absorbers 20 are fixedly connected to the front and rear sides of the top and bottom inside the inner cavity of the connection frame 13. One end of each second spring shock absorber 20 is fixedly connected to the surface of the cross plate 19. The cross plate 19 is fixedly connected to the third sliding blocks 18 on both sides through connecting members, ensuring that when the cross plate 19 is vibrated, it can move up and down stably; and a rubber elastic block 21 is arranged inside the connection frame 13, so that the swing of the cross plate 19 will not directly contact the connection frame 13.

[0026] Rubber elastic blocks 21 are arranged between the two second spring shock absorbers 20 at both the top and bottom inside the inner cavity of the connection frame 13.

[0027] A second long groove 22 for cooperating with the bolt 12 is formed on the side surface of the side grip connection box 10. A round hole 23 for cooperating with the bolt 12 is formed inside the cross plate 19. One end of the bolt 12 passes through the round hole 23 inside the connection frame 13 and extends to the outside of the connection frame 13.

[0028] A plurality of threaded holes 24 for cooperating with the bolt 12 are formed on the other side surface of the side grip connection box 10. Scale lines corresponding to the threaded holes 24 can be arranged on the side of the second long groove 22. The operator can determine the appropriate position to tighten the bolt 12 by selecting scale lines at different heights, so as to fix the grip 11.

[0029] The second long groove 22 is provided on the side surface of the side grip connection box 10. Marking lines corresponding to the screw holes 24 are engraved on the edge of the second long groove 22. The operator can first unscrew the bolt 12, move the grip 11 to slide up and down in the side grip connection box 10, and then tighten the bolt 12 after sliding to a suitable position to find a suitable holding position. During operation, the operator can turn on the equipment for crushing work. The crushing equipment will generate strong vibrations during work. The vibrations received by the grip 11 are sequentially transmitted through the crushing body 1, the side grip connection box 10, the bolt 12, the cross plate 19, the second spring shock absorber 20, and the connection frame 13, and finally transmitted to the grip 11. If the vibration is too large, the cross plate 19 will contact the rubber elastic block 21 to avoid rigid collision between the cross plate and the connection frame 13. The vibrations received by the handle are transmitted through the crushing body 1, the connecting sleeve 2, and the first spring shock absorber 7, and finally transmitted to the handle 6. The first slider 4 slides up and down in the first chute 3. The handle 6 is slidably connected to the crushing body 1 through the first slider 4. An elastic buffer pad 8 is provided at the overlapping part of the connecting sleeve 2 and the handle 6. The grip 11 and the handle 6 are both shock-absorbed and buffered by the first spring shock absorber 7 and the second spring shock absorber 20, avoiding harm to the operator caused by strong and continuous vibrations, and improving the health and safety of the operator when using the handheld crushing equipment.
