[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a multifunctional percussion hammer, including a handle 1 and a hammer head 4. A U-shaped plate 2 is fixedly installed on the right end of the handle 1. A folding rod 3 is rotatably connected to the right end of the U-shaped plate 2 through a pin. The hammer head 4 is fixedly installed on the top right end of the folding rod 3. A snap-fit ​​mechanism 5 is provided between the U-shaped plate 2 and the folding rod 3. A tongue depressor mechanism 6 is provided inside the folding rod 3.

[0022] The locking mechanism 5 includes a through hole 501, a semi-circular slot 502, and a guide rod 504. The through hole 501 is located at the top and bottom of the folding rod 3 and communicates with the interior of the folding rod 3. The through hole 501 is located on the inner wall of the U-shaped plate 2. The top and bottom ends of the guide rod 504 are fixedly connected to the inner wall of the folding rod 3. A connecting plate 503 is slidably sleeved on the outer wall of the guide rod 504. There are two connecting plates 503, and two semi-circular blocks 506 are fixedly installed on the outer wall of each connecting plate 503. The semi-circular blocks 506 extend from the through hole 501, and the two semi-circular blocks 506 near the semi-circular slot 502 are engaged in the semi-circular slot 502. A spring 505 connects the two connecting plates 503. In use, the folding rod 3 can be rotated out of the U-shaped plate 2, utilizing the semi-circular slot 504. The locking block 506 is inserted into the semi-circular slot 502 to fix the folding rod 3. When not in use, the folding rod 3 is folded into the U-shaped plate 2 for easy carrying. Since the hammer head 4 is located at the top right end of the folding rod 3, the force applied during use is perpendicular to the torque required for the rotation of the folding rod 3, thus preventing the folding rod 3 from being rotated by force. The guide rod 504 is set to guide the connecting plate 503, so that the connecting plate 503 can only slide up and down relative to the folding rod 3. That is, during the rotation of the folding rod 3, the edge of the U-shaped plate 2 presses against the semi-circular locking block 506, causing the semi-circular locking block 506 to be retracted into the through hole 501. After the semi-circular locking block 506 is aligned with the semi-circular slot 502, the spring 505 pushes the connecting plate 503 to move, thereby causing the semi-circular locking block 506 to be inserted into the semi-circular slot 502.

[0023] The tongue depressor mechanism 6 includes a slide groove 601, a reset groove 602, and a slide rail 603. Both the slide groove 601 and the reset groove 602 are located on the outer wall of the folding rod 3. The reset groove 602 is connected to the left end of the slide groove 601 and is located above the slide groove 601. The slide rail 603 is slidably mounted inside the folding rod 3. A second spring 604 is fixedly installed on the top of the slide rail 603, and the top end of the second spring 604 is fixedly connected to the inner wall of the folding rod 3. A tongue depressor plate 605 is slidably mounted inside the slide rail 603. A T-shaped strip 606 is fixedly installed on the bottom of the tongue depressor plate 605. The T-shaped strip 606 rests against... Near the left end of the tongue depressor 605, the two ends of the T-shaped strip 606 away from the tongue depressor 605 extend out from the reset groove 602. When the tongue depressor 605 is not in use, the tongue depressor 605 is located inside the folding rod 3. When the tongue depressor 605 needs to be used, pull down the T-shaped strip 606 to move the tongue depressor 605 down, which in turn moves the slide rail 603 down, causing the slide rail 603 to stretch the second spring 604. After pulling the end of the T-shaped strip 606 into the slide groove 601, the T-shaped strip 606 can be pulled to move the tongue depressor 605. The right end of the tongue depressor 605 extends out from inside the folding rod 3, and the tongue depressor 605 can then be used.

[0024] A reinforcing rod 11 is fixedly installed at the bottom of the U-shaped plate 2. The length of the reinforcing rod 11 is the same as the length of the U-shaped plate 2. Because the force generated by the hammer 4 when it strikes is vertically applied to the U-shaped plate 2, setting a reinforcing rod 11 at the bottom of the U-shaped plate 2 can increase the strength of the U-shaped plate 2 and prevent the U-shaped plate 2 from undergoing deformation that cannot be recovered.

[0025] The bottom of the hammer head 4 is provided with an integrally formed connecting handle 401, and the top of the U-shaped plate 2 is provided with an arc-shaped groove 9. The inner diameter of the arc-shaped groove 9 is the same as the outer diameter of the connecting handle 401. When the folding rod 3 is folded into the U-shaped plate 2, the connecting handle 401 is inserted into the arc-shaped groove 9, so that the hammer head 4 will not obstruct the process of the folding rod 3 retracting into the U-shaped plate 2. At the same time, after the folding rod 3 is retracted into the U-shaped plate 2, the hammer head 4 is still located outside the U-shaped plate 2, and the hammer head 4 can also be used.

[0026] A light 10 is fixedly installed on the top of the U-shaped plate 2. The light 10 is close to the right end of the U-shaped plate 2. A measuring tape 8 is fixedly installed on the left end of the handle 1.

[0027] A pressing plate 7 is fixedly installed at the end of the T-shaped bar 606 that extends from the reset groove 602. The outer diameter of the pressing plate 7 is larger than the inner diameter of the reset groove 602. The pressing plate 7 is provided so that the user can press down the T-shaped bar 606 to move the end of the T-shaped bar 606 into the slide groove 601.

[0028] Working principle: When the tongue depressor 605 needs to be used, pull down the T-shaped bar 606 to move the tongue depressor 605 downwards, which in turn moves the slide rail 603 downwards. This causes the slide rail 603 to stretch the spring 604, pulling the end of the T-shaped bar 606 into the slide groove 601. Then, pulling the T-shaped bar 606 can move the tongue depressor 605, allowing the right end of the tongue depressor 605 to extend from the folding rod 3, thus enabling its use. Reversing the operation retracts the tongue depressor 605 back into the folding position. Inside the folding rod 3, when carrying and storing, rotating the folding rod 3 causes the semi-circular locking block 506, which is engaged in the semi-circular locking groove 502, to move into the through hole 501 under force. After the folding rod 3 is folded back into the U-shaped plate 2, the semi-circular locking block 506 near the semi-circular locking groove 502 is no longer under force. At this time, the spring 505 pushes the connecting plate 503 to move, thereby causing the semi-circular locking block 506 to engage in the semi-circular locking groove 502, thus fixing the folding rod 3.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
