Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a handheld crusher. Background Technology

[0002] Rock drills are tools used to directly extract stone. They drill holes in rock strata to insert explosives to blast the rock, thereby completing the extraction of stone or other rock excavation projects. In addition, rock drills can also be used as breakers to break hard layers such as concrete. Currently, handheld rock breakers generate significant vibrations during use. These vibrations are transmitted to the operator's hands through the machine body. When the hands are subjected to vibrations for a long time, it affects the operator's stability in holding the machine and increases the possibility of the handheld rock breaker slipping from the hand. This needs to be improved. Utility Model Content

[0023] Please see Figure 1-4 This utility model provides a technical solution: a handheld crusher, including a body 1, a drill rod 2 at the lower end of the body 1, a main handle 3 fixedly installed at the upper end of the body 1, and a secondary handle 4 fixedly connected to the outer surface of the body 1. The surface of the secondary handle 4 is provided with an elastic band 5. By providing the elastic band 5 on the surface of the secondary handle 4, the hand can be tied to the secondary handle 4, and the secondary handle 4 can be used in conjunction with the main handle 3 to make it easier for people to lift the entire body 1. A threaded hole a6 is opened on the surface of the secondary handle 4, and a hand-tightening screw 7 is passed through the surface of the elastic band 5. The threaded design on the surface of the secondary handle 4 further enhances its appeal. Hole a6, and a hand screw 7 is provided through the surface of the elastic band 5. After the hand screw 7 is screwed into the threaded hole a6, one end of the elastic band 5 can be pressed and fixed. The surface of the elastic band 5 has a groove 8. A limiting plate 9 is fixedly installed on the surface of the secondary grip 4. By setting the groove 8 on the surface of the elastic band 5 and the limiting plate 9 fixedly installed on the surface of the secondary grip 4, when the limiting plate 9 passes through the inside of the groove 8, the other end of the elastic band 5 can be fixed. A rubber sleeve 10 is provided on the outer surface of the secondary grip 4 to increase the anti-slip properties of the surface of the secondary grip 4.

[0024] Please see Figure 1-4 A movable handle 11 is provided on the side of the body 1. By providing a movable handle 11 on the side of the body 1, the movable handle 11 can increase the gripping points on the surface of the body 1, making it easier for people to lift the body 1. A threaded post 12 is fixedly installed at one end of the movable handle 11. A threaded hole b13 is opened on the side surface of the body 1. The threaded hole b13 is adapted to the threaded post 12. By setting the threaded hole b13 on the side surface of the body 1 and setting the threaded hole b13 to be adapted to the threaded post 12, the movable handle 11 can be installed on the threaded hole b13 through the threaded post 12. The limiting plate 9 is smaller than the width of the slot 8. By setting the limiting plate 9 to be smaller than the width of the slot 8, the limiting plate 9 can pass through the inside of the slot 8. The limiting plate 9 is located inside the slot 8.

[0025] Example 2

[0026] Please see Figure 2 and Figure 3 An auxiliary mechanism is provided on the outer surface of the drill rod 2. The auxiliary mechanism includes an assembly plate 14, which is fixedly mounted on the outer surface of the drill rod 2. By installing the assembly plate 14 on the outer surface of the drill rod 2, it can support the baffle 15. The side of the assembly plate 14 is provided with a baffle 15 to block splashed stone particles. The side of the baffle 15 is fixedly connected with a rod 16, which is inserted into the surface of the assembly plate 14. By setting the side of the baffle 15 to be fixedly connected with the rod 16 and the rod 16 inserted into the surface of the assembly plate 14, the baffle 15 can be installed on the assembly plate 14 through the rod 16. The surface of the baffle 15 is fixedly provided with a protruding strip 17, which can trap some of the splashed stone particles and reduce the possibility of secondary splashing of stone particles.

[0027] Working principle: The machine consists of a body 1, drill rod 2, main handle 3, auxiliary handle 4, elastic band 5, threaded hole a6, hand screw 7, slot 8, limiting plate 9, and rubber sleeve 10. Before using the crusher, move the elastic band 5 to the surface of the auxiliary handle 4. Then, pass the hand screw 7 through the surface of the elastic band 5 and screw it into the threaded hole a6, fixing one end of the elastic band 5 to the auxiliary handle 4. Next, select a suitable slot 8 according to the operator's hand size. After selection, use the slot 8 to fit the other end of the elastic band 5 onto the limiting plate 9. The limiting plate 9 will pass through the slot 8, tightening the elastic band 5 onto the auxiliary handle 4. Take the rubber sleeve 10 and put it on the secondary grip 4. When holding the secondary grip 4, the elastic band 5 can bind the hand to the secondary grip 4, while the rubber sleeve 10 increases the anti-slip property, allowing people to hold the secondary grip 4 more firmly. Then, use the secondary grip 4 and the main grip 3 to lift the machine body 1 for use. By setting the auxiliary mechanism, the baffle 15 is moved at this time. During the movement of the baffle 15, the insertion rod 16 moves with the baffle 15. Then, use the insertion rod 16 to insert the baffle 15 into the assembly plate 14. The baffle 15 is then connected to the drill rod 2 through the assembly plate 14 and blocks a large number of flying stone particles to avoid too many stone particles flying onto the body.
