[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] like Figures 1-4As shown, this utility model provides a technical solution: a claw hammer for vehicle repair, comprising: a claw hammer body 1; a connecting rod 2 is fixedly installed on one outer wall of the claw hammer body 1, and the connecting rod 2 is perpendicular to the claw hammer body 1; a sleeve 3 is slidably sleeved on the outside of the connecting rod 2, and the sleeve 3 rotates outside the connecting rod 2; an adjustment module 5 is provided on the outside of the sleeve 3, and the adjustment module 5 is at least used to release and lock the connection between the connecting rod 2 and the sleeve 3; a tip 6 is fixedly installed at the bottom of the claw hammer body 1; and a force application component 7 is provided at the top of the claw hammer body 1, and the force application component 7 is at least used to increase the impact force when the claw hammer body 1 drives the tip 6 to strike vehicle parts.

[0021] In this embodiment, it includes: a claw hammer body 1, which is a cylindrical structure and is made of alloy steel; a threaded head 11 is provided on the top of the claw hammer body 1, and a force application component 7 is detachably connected to the top of the claw hammer body 1 through the threaded head 11; the collar 71 at the bottom of the force application component 7 is threaded onto the threaded head 11.

[0022] It should be noted that when the force application component 7 is required (when the part needs to be struck hard), the force application component 7 can be mounted on the top of the claw hammer body 1. When the claw hammer body 1 is not needed, the force application component 7 can be removed from the top of the claw hammer body 1, and the claw hammer body 1 can be used alone, which improves the flexibility of the claw hammer body 1.

[0023] In this embodiment, a connecting rod 2 is fixedly installed on one outer wall of the claw hammer body 1, and the connecting rod 2 is perpendicular to the claw hammer body 1. The claw hammer body 1 and the connecting rod 2 are processed by welding to make them an integral structure. A pin 21 is provided on the outside of one end of the connecting rod 2. The pin 21 is slidably inserted into the inside of the sleeve 3. The pin 21 is a cylindrical structure. By sliding the pin 21 inside the sleeve 3 and achieving limiting, the stability of the connection of the connecting rod 2 inside the sleeve 3 is ensured. By moving the pin 21 inside the sleeve 3, the relative length of the connecting rod 2 and the sleeve 3 is changed.

[0024] In this embodiment, a sleeve 3 is slidably sleeved on the outside of the connecting rod 2, and the sleeve 3 rotates outside the connecting rod 2. An adjustment module 5 is provided on the outside of the sleeve 3. The adjustment module 5 is used to at least release and lock the connection between the connecting rod 2 and the sleeve 3. The adjustment module 5 includes a straight groove 51 provided on the outer wall of one side of the sleeve 3. A plurality of limiting ports 52 communicating with the straight groove 51 are provided on one side of the straight groove 51. A blocking strip 53 is provided inside the straight groove 51. The blocking strip 53 can be made of metal or elastic rubber material. When using metal, a magnet can be provided inside the straight groove 51 or a bolt can be used to achieve a fixed connection between the metal and the sleeve 3. When using elastic rubber material, it only needs to be deformed by force and inserted into the straight groove 51 to ensure its stability inside the straight groove 51. The blocking strip 53 is used to limit the pin head 21 inside the limiting port 52.

[0025] When it is necessary to adjust the relative length between the connecting rod 2 and the sleeve 3, the operation steps are as follows: first, remove the plug 53 from the inside of the straight groove 51; then, rotate the sleeve 3 so that the pin 21 on the connecting rod 2 moves out from the inside of the limiting port 52 and enters the inside of the straight groove 51. At this time, the sleeve 3 slides straight along the connecting rod 2. After adjusting to the appropriate length, the pin 21 is re-entered into the corresponding limiting port 52. Finally, the plug 53 is reinserted into the inside of the straight groove 51 to ensure the connection stability between the sleeve 3 and the connecting rod 2.

[0026] In this embodiment, a pointed tip 6 is fixedly installed at the bottom of the claw hammer body 1. The claw hammer body 1 and the pointed tip 6 are an integral structure, both of which are made of alloy steel, ensuring their rigidity and strength, and making it easier to lift and strike parts during vehicle maintenance. The pointed tip 6 consists of two parts: a conical structure and a curved pointed structure.

[0027] In this embodiment, a force-applying component 7 is provided on the top of the claw hammer body 1. The force-applying component 7 is used at least to increase the impact force when the claw hammer body 1 drives the tip 6 to strike the vehicle parts. The force-applying component 7 includes a collar 71 threadedly connected to the top of the claw hammer body 1. The top of the collar 71 has several equally spaced, ring-shaped surrounding plates 74, forming an outer frame structure for guiding the gravity ball 75. The openwork design also enhances its aesthetics. A threaded ring 72 is located at the top of the surrounding plates 74, and a sealing plug 73 is located above the inside of the threaded ring 72. The gravity ball 75 is placed inside the cavity between the surrounding plates 74, the sealing plug 73, and the collar 71. Since copper balls have the highest density and therefore the greatest gravity for the same volume, the gravity ball 75 is made of rotatable pure copper to ensure its impact force. When the worker holds the handle 4 and rapidly raises the claw hammer in an arc, the gravity ball 75 moves to the top inside the surrounding plates 74. When the worker strikes the part downwards, the tip 6 of the claw hammer quickly contacts the part, and the gravity ball 75 strikes again as it descends, improving the force application effect of the claw hammer.

[0028] In this embodiment, a handle 4 is fixedly connected to the end of the sleeve 3. The end of the handle 4 is chamfered, and the outer wall of the handle 4 is provided with anti-slip texture. The handle 4 is covered with an outer sleeve made of composite material, such as glass fiber or carbon fiber, to improve lightness and impact resistance.
