When faced with a bolt that is difficult to remove, the insufficient handle length may not provide sufficient force, resulting in an inability to remove the bolt. In addition, existing wrenches generally do not have a protective function. When using the wrench, when the wrench is twisted quickly, the hand holding the wrench is likely to hit the equipment that installs the bolt, thereby causing hand injuries.
[0004] Therefore, the utility model provides a product disassembly and assembly wrench with a protective device to solve the above problems. Utility Model Content

[0017] Beneficial effects
[0018] The utility model provides a product disassembly and assembly wrench with a protective device. Compared with the prior art, it has the following beneficial effects:
[0019] 1. When the operator's hand accidentally hits the equipment with the protective device of the product disassembly wrench, the outer protective plate will touch the equipment first. The protective plate is made of hard rubber with a certain toughness. The protective plate touches the equipment first to protect the operator's hand, reducing the damage to the operator's hand caused by the impact of the equipment, thereby realizing the protective function of the wrench.
[0020] 2. The disassembly and assembly wrench with a protective device uses a pulling block to pull the auxiliary rod out from the inside of the handle. After pulling it out, the force arm can be increased by applying force to the pulling block, thereby greatly increasing the force acting on the bolt at the other end. This solves the problem that when facing a bolt that is more difficult to remove, the handle may not be long enough to provide sufficient force, resulting in the inability to remove the bolt.

Therefore, they cannot be understood as limitations on the present application. The terms "install", "connect", and "connected" should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be directly connected, or indirectly connected through an intermediate medium, or they can be internal connections between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0028] The present application will be further described in detail below through the accompanying drawings and examples.
[0029] Reference Figures 1 to 4The embodiment of the present application provides a product disassembly and assembly wrench with a protective device, including a handle 1, a mounting plate 5 fixedly installed on the front of the handle 1, a disassembly and assembly component 2 is provided at the bottom of the mounting plate 5, a protective component 3 is provided on the outside of the handle 1, and an auxiliary component 4 is provided inside the handle 1. The protective component 3 includes a protective plate 31, and cross plates 32 are fixedly installed on the front and rear sides of the protective plate 31. The cross plates 32 are attached to the front and rear sides of the handle 1, and mounting bolts 33 are fixedly installed between the cross plates 32 and the handle 1. The mounting bolts 33 pass through the inside of the cross plates 32 and are screwed to the inside of the handle 1. Anti-slip grooves 6 are provided on both sides of the handle 1, and the anti-slip grooves 6 are located between the front and rear cross plates 32.
[0030] Auxiliary assembly 4 includes an auxiliary rod 44, which is inserted into handle 1. A pull block 41 is fixedly mounted on the back of auxiliary rod 44, located outside and behind handle 1. A magnet 43 is fixedly mounted on the top of auxiliary rod 44. A slide slot 42 is defined at the top of handle 1, and magnet 43 slides within slide slot 42. Handle 1 is made of stainless steel, and the outer side of magnet 43 fits into slide slot 42 and is attracted to its inner wall.
[0031] In this embodiment, when the wrench is in use, the operator holds the handle 1, and the anti-slip groove 6 on the outside of the handle 1 ensures stability when holding the handle 1. When the handle 1 is held tightly, the protective plates 31 are just located on both sides of the operator's hands. When the operator's hands accidentally hit the equipment, the outer protective plates 31 touch the equipment first, and the protective plates 31 are made of hard rubber with a certain toughness. The protective plates 31 touch the equipment first to protect the operator's hands, reducing the damage to the operator's hands caused by the equipment collision, thereby realizing the protection function of the wrench; and when using the wrench, if it is necessary to increase the force acting on the bolt, The auxiliary rod 44 can be pulled out from the inside of the handle 1 by the pulling block 41. After being pulled out, the force arm of the time force can be increased by applying the force to the pulling block 41, thereby greatly increasing the force acting on the bolt at the other end, thereby solving the problem that when facing a bolt that is more difficult to remove, the handle 1 may not be long enough to provide sufficient force, resulting in the inability to remove the bolt; and the setting of the magnet block 43 and the slide groove 42 restricts the movement of the auxiliary rod 44 through the magnet block 43, so that the auxiliary rod 44 is completely moved out of the handle 1, and the stability of the auxiliary rod 44 after movement can be ensured by the suction between the magnet block 43 and the handle 1.
[0032] Reference Figures 1 to 4 In one aspect of this embodiment, the disassembly and assembly component 2 includes a wrench head 21, a mounting block 22 is fixedly mounted on the top of the wrench head 21, and an insert block 24 is fixedly mounted on the bottom of the mounting plate 5, and the insert block 24 is inserted into the slot 23.
[0033] The cross-sections of the insert block 24 and the slot 23 are square and of equal size. The top of the mounting block 22 is affixed to the bottom of the mounting plate 5. A socket 27 and a screw hole 28 are defined within the mounting block 22. A central hole 26 is defined within the insert block 24. Central hole 26, socket 27, and screw hole 28 are aligned. A first bolt 25 extends through the central hole 26, socket 27, and screw hole 28. The bottom end surface of the first bolt 25 is threaded and screwed into the screw hole 28.
[0034] In this embodiment, the bolt is assembled and disassembled by putting the wrench head 21 on the bolt and rotating the wrench head 21 by the handle 1. The first bolt 25 is removed from the middle hole 26, the insertion hole 27 and the screw hole 28, and the fixation between the insert block 24 and the slot 23 can be released, so that the mounting block 22 and the wrench head 21 below can be disassembled. Wrench heads 21 of different sizes are respectively provided under a plurality of mounting blocks 22 and the slot 23 of the same size. The wrench heads 21 of different sizes are installed through the insert block 24 and the first bolt 25, so that the wrench can assemble and disassemble bolts of different sizes.
[0035] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0036] Working principle: When the wrench is in use, the operator holds the handle 1, and the anti-slip groove 6 on the outside of the handle 1 ensures stability when holding the handle 1. When holding the handle 1, the protective plates 31 are just located on both sides of the operator's hands. When the operator's hands accidentally hit the equipment, the outer protective plates 31 touch the equipment first, and the protective plates 31 are made of hard rubber with a certain toughness. The operator's hands can be protected by the protective plates 31 touching the equipment first, reducing the damage to the operator's hands caused by the impact of the equipment, thereby realizing the protection function of the wrench; and when using the wrench, if it is necessary to increase the force acting on the bolt, the auxiliary rod 44 can be pulled out from the inside of the handle 1 through the pull block 41. After pulling it out, by applying the force to the pull block 41, the force arm of the time force can be increased, thereby greatly increasing the force acting on the bolt at the other end, thereby solving the problem that when facing a bolt that is more difficult to remove, the handle 1 is not long enough and may not be able to be lifted. The screwdriver 24 is pressed against the screwdriver 25 and the screwdriver 26 is pressed against the screwdriver 27 to release the screwdriver 26. The screwdriver 24 is pressed against the screwdriver 27 and the screwdriver 26 is pressed against the screwdriver 27. The screwdriver 24 is pressed against the screwdriver 27 to release the screwdriver 26.
