[0025] Specific examples are given below.

[0026] like Figure 1 、 2As shown in , 3 and 5, a hollow hammer for green building management comprises a handle 1; a telescopic rod 11 is installed on the top of the handle 1; a pin 12 is slidably connected to the top of the telescopic rod 11; a hammer head 13 is fixed to the top of the pin 12; a rotating rod 14 is threadedly connected to the middle of the telescopic rod 11; two groups of first grooves 15 are opened in the middle of the rotating rod 14; multiple groups of rubber plates 16 are fixed to the inner wall of the pin 12, and the rubber plates 16 are inclined upward; the rotating rod 14 is slidably set on the inner wall of the pin 12; when working, the staff needs to install the handle 1 together, and then pull the telescopic rod 11 to the outside to make it telescopic as a whole. When a new hammer head 13 needs to be installed at the end of the telescopic rod 11, the staff can align the pin 12 with the designated position at the top of the telescopic rod 11, and push the top of the hammer head 13. During the descent of the pin 12, the horizontal rotating rod 14 will pass through the middle of the pin 12 and the multiple groups of inclined rubber plates. The first groove 15 is squeezed and reinforced as a whole by the upward reset force of the rubber plate 16, thereby further reducing the problem of its shaking.

[0027] like Figure 1-3As shown, the outer wall of the telescopic rod 11 is fixed with two groups of spring rods 2; the output end of the spring rod 2 is fixed with a convex piece 21; the side wall of the convex piece 21 is slidably connected with a pull rope 22; the middle of the pull rope 22 is fixed with an impact ball 23; the inner wall of the output end of the telescopic rod 11 is fixed with two groups of elastic ropes 24; the end of the elastic rope 24 is fixed with a card plate 25, and the card plate 25 is slidably arranged on the inner wall of the convex piece 21; the pull rope 22 is located at the bottom of the card plate 25; when working, by arranging two groups of spring rods 2 in the middle of the telescopic rod 11, the staff can then fix one end of the pull rope 22 to the output end of one group of spring rods 2, and at the same time, the other end of the pull rope 22 can slide in the middle of the convex piece 21, and after the tension of the pull rope 22 is adjusted to the appropriate position, the staff can loosen the card plate 25 so that the card plate 25 will lose its supporting force and will The impact ball 23 is used to move the hammer head 13 on the wall, and the impact ball 23 is used to move the hammer head 13 on the wall. ...

[0028] like Figure 2 and 4 When the operator presses the latch 12 downwards, the middle of the latch 12 will directly contact the inner wall of the scraper 31 . After the latch 12 reaches the designated position and is fixed, the middle of the elastic member 3 will be squeezed and a reaction force will be generated, so that the hammer head 13 can be pushed upwards for a short distance and fill the gap between the rubber plate 16 and the contact end of the first groove 15 . This step is combined with the scraper 31 to reduce the accumulation of impurities in the middle of the latch 12 , so that after the middle of the latch 12 , impurities accumulate and subsequent movement becomes troublesome. At the same time, under the reaction of the elastic member 3 , the problem of shaking of the hammer head 13 during operation can be further reduced.

[0029] like Figure 3As shown, the end of the pull rope 22 is fixed with a magnet 4; the outer wall of the telescopic rod 11 is fixed with a metal plate 41, and the magnet 4 and the metal plate 41 are arranged to attract each other; during operation, by arranging the magnet 4 at the end of the pull rope 22, when the end of the pull rope 22 leaks out to the outside world for a long time, the staff can move the magnet 4 close to the position of the metal plate 41, so that the two generate suction and fix together. This step, combined with the arrangement of the magnet 4, can reduce the leakage position of the end of the pull rope 22, so that when the handle 1 is manually swung, the pull rope 22 will continue to shake and interfere with the vision of the staff.

[0030] like Figure 4 As shown, a second groove 5 is provided on the top of the scraper 31, and the second groove 5 and the bottom of the hammer head 13 are matched in shape; when working, a recessed second groove 5 is provided in the middle of the scraper 31, so that after the hammer head 13 is close to the scraper 31, its bottom will be deeply in contact with the second groove 5. This step, combined with the second groove 5, can increase the contact area when fixing the hammer head 13. At the same time, the recessed second groove 5 can collect some impurities scraped off the inner wall of the scraper 31 for subsequent cleaning of the impurities.

[0031] like Figure 3 As shown, multiple groups of rubber pads 6 are fixed to the bottom of the card plate 25, and the multiple groups of rubber pads 6 are arranged in contact with the pull rope 22; when working, by arranging rubber pads 6 on the inner wall of the card plate 25, when the card plate 25 slides under the action of the elastic rope 24 and approaches the position of the pull rope 22, the rubber pads 6 will directly contact the middle of the pull rope 22. This step is combined with the multiple groups of rubber pads 6 that are arranged, which can protect the middle part of the pull rope 22 when squeezing it, and at the same time can increase the friction between the two, thereby reducing the problem of slipping between the pull rope 22 and the card plate 25.

[0032] like Figure 5 As shown, the inner wall of the first groove 15 is fixed with a raised plate 7, and the raised plate 7 is arranged in contact with the rubber plate 16; during operation, by providing the uneven raised plate 7 on the inner wall of the first groove 15, when one side of the first groove 15 is close to the rubber plate 16, the bent rubber plate 16 will squeeze the raised raised plate 7. This step reduces the surface of the rubber plate 16 after long-term use, which makes it easier for the surface of the rubber plate 16 to slip when the first groove 15 is subsequently fixed.

[0033] Working principle: After the handle 1 is installed together, the telescopic rod 11 can be pulled outward to make it telescopic as a whole. When a new hammer head 13 needs to be installed at the end of the telescopic rod 11, the staff can align the bayonet 12 with the designated position at the top of the telescopic rod 11 and push the top of the hammer head 13. During the descent of the bayonet 12, the horizontal rotating rod 14 will pass through the middle of the bayonet 12 and multiple groups of inclined rubber plates 16. After the rotating rod 14 contacts the inner wall of the bayonet 12, the staff can use a tool to rotate the end of the rotating rod 14, so that the vertical first groove 15 changes to a horizontal position, and the inner wall of the first groove 15 contacts the top of the rubber plate 16. , and the rubber plate 16 is tilted to limit and fix the latch 12 as a whole. At the same time, when the latch 12 needs to be taken out again, the end of the rotating rod 14 can be rotated again. By setting two groups of spring rods 2 in the middle of the telescopic rod 11, the staff can then fix one end of the pull rope 22 to the output end of one group of spring rods 2, and the other end of the pull rope 22 can slide in the middle of the protrusion 21. After the tension of the pull rope 22 is adjusted to a suitable position, the staff can loosen the card plate 25, so that the card plate 25 will move downward after losing its supporting force, and squeeze the pull rope 22 that passes through the middle of the protrusion 21, so that the surface depth of the pull rope 22 contacts the inner wall of the protrusion 21, and tighten it. The fixing work is carried out, and when the staff swings the hammer head 13 on the wall to work, the impact ball 23 will continuously hit the surface of the telescopic rod 11 and generate a vibration force. By providing two sets of elastic members 3 on the top of the telescopic rod 11, when the staff presses the bayonet 12 as a whole, the middle of the bayonet 12 will directly contact the inner wall of the scraper 31. After the bayonet 12 reaches the designated position for fixing, the middle of the elastic member 3 will be squeezed and a reaction force will be generated, so that the hammer head 13 can be pushed upward for a short position and fill the gap between the contact end of the rubber plate 16 and the first groove 15. By providing a magnet 4 at the end of the pull rope 22, the end of the pull rope 22 is exposed to the outside. When the boundary is long, the staff can move the magnet 4 close to the metal plate 41 so that the two generate suction and are fixed together. By providing a recessed second groove 5 in the middle of the scraper 31, the bottom of the hammer head 13 will be deeply in contact with the second groove 5 after it approaches the scraper 31. By providing a rubber pad 6 on the inner wall of the card plate 25, when the card plate 25 slides under the action of the elastic rope 24 and approaches the pull rope 22, the rubber pad 6 will directly contact the middle of the pull rope 22. By providing an uneven raised plate 7 on the inner wall of the first groove 15, when one side of the first groove 15 is close to the rubber plate 16, the bent rubber plate 16 will squeeze the raised raised plate 7.
