[0030] The embodiment of the present application provides a multifunctional wrench that is easy to disassemble and replace, and the multifunctional wrench that is easy to disassemble and replace is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.
[0031] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.
[0032] Example 1
[0033] See also Figure 1-6In the embodiment, a multifunctional wrench that is easy to disassemble and replace includes: a wrench body 1, a hook wrench 4 is provided at one end of the wrench body 1, and a wrench head 302 is provided at the end of the wrench body 1 away from the hook wrench 4.
[0034] Among them, through the setting of the disassembly component, the wrench head 302 can be quickly replaced according to the shape of the bolt or the size and shape of other fasteners for maintenance and disassembly, thereby improving the applicability of the wrench body 1. There is no need for maintenance personnel to carry wrench bodies 1 of different sizes and shapes, thereby reducing the burden on maintenance personnel.
[0035] Example 2
[0036] On the basis of Example 1, a disassembly component is provided between the wrench body 1 and the wrench head 302 for quickly replacing different wrench heads 302 for use, and the disassembly component includes: a mounting groove 2 provided at the end of the wrench body 1, a mounting block 3 connected to one end of the wrench head 302, and the mounting block 3 is located in the mounting groove 2; a receiving groove 201 provided on the upper and lower surfaces of the wrench body 1, a mounting hole communicating with the mounting groove 2 is provided inside the receiving groove 201; a fixing block 203 is penetrated inside the mounting hole, one end of the fixing block 203 protrudes from the outer surface of the wrench body 1 and is connected to the pull plate 202, a fixing hole 301 matching with the fixing block 203 is provided on the upper and lower surfaces of the mounting block 3, one end of the fixing block 203 extends into the fixing hole 301, a reset spring 204 is provided in the receiving groove 201, and the reset spring 204 is sleeved on the outside of the fixing block 203, and the two ends of the reset spring 204 are respectively connected to the inner wall of the receiving groove 201 and the pull plate 202.
[0037] In the process of repairing and disassembling the equipment, since there are a large number of bolts or other fixing structures of different sizes on the equipment, and the existing wrench body 1 has only one end with a wrench head 302, and the shape and size of the wrench head 302 is fixed, it is necessary to use wrenches of different sizes and shapes for disassembly, and the maintenance personnel cannot carry a large number of wrenches of different sizes and properties, which is very inconvenient. At this time, the wrench head 302 can be disassembled and replaced with the corresponding wrench head 302 to meet the needs of repair and disassembly, and carrying the wrench head 302 can reduce the weight carried by the maintenance personnel compared with carrying the entire wrench body 1;
[0038] When removing the wrench head 302, the fixing block 203 can be pulled apart from the fixing hole 301 by the pull plate 202, thereby releasing the fixation of the wrench head 302, and the wrench head 302 can be taken out, and then the mounting block 3 on the new wrench head 302 can be inserted into the mounting groove 2. At this time, the pull plate 202 is released, so that the pull plate 202 rebounds under the action of the elastic force of the return spring 204, so that the fixing block 203 is inserted into the fixing hole 301, completing the clamping fixation of the wrench head 302.
[0039] Example 3
[0040] On the basis of Example 1, an adjustment component is provided inside the wrench body 1 for adjusting the overall length of the wrench body 1. The wrench body 1 is composed of a hand-held block and a connecting block. The adjustment component includes: two adjustment rods 401 connected to one side of the hand-held block, and a plurality of adjustment holes 402 are provided on the opposite sides of the adjustment rods 401; two adjustment slots 101 are provided on one side of the hand-held block, and the adjustment slots 101 are adapted to the adjustment rods 401; a movable slot 102 is provided inside the hand-held block, and two clamping blocks 107 are provided in the movable slot 102, and one end of the clamping block 107 extends to In the adjustment hole 402, a movable spring 103 is connected to the inside of the movable groove 102, one end of the movable spring 103 is connected to a movable block 104, a sliding groove communicating with the movable groove 102 is opened on the surface of the hand-held block, a moving block 105 with a T-shaped structure is connected to the surface of the movable block 104, and one end of the moving block 105 protrudes from the outer surface of the hand-held block, one side of the movable block 104 is rotatably connected to two connecting rods 106 through a rotating shaft, and the two connecting rods 106 are symmetrically arranged, and the end of the connecting rod 106 away from the movable block 104 is connected to the clamping block 107 through a rotating shaft.
[0041] Among them, a limiting groove 108 is opened on the opposite side of the two clamping blocks 107, and a limiting spring 1091 is connected inside the limiting groove 108. A limiting rod 109 is connected between the two limiting springs 1091, and both ends of the limiting rod 109 extend into the limiting groove 108.
[0042] When the wrench body 1 is used, since the length of the wrench body 1 is fixed, it is easily limited by the maintenance space during the process of removing the bolt. At this time, the overall length of the wrench body 1 can be adjusted to adapt to the narrow maintenance space, and at the same time, the length of the wrench body 1 can be increased to the maximum extent within the limited maintenance space, thereby increasing the torque in the direction of the user and reducing the force applied by the maintenance personnel;
[0043] When adjusting the length of the wrench body 1, the movable block 104 can be pulled by the moving block 105 to squeeze the movable spring 103, so that the movable spring 103 is squeezed to generate elastic force, and at the same time, the movable block 104 drives one end of the two connecting rods 106 to move, so that the connecting rods 106 pull the clamping block 107 into the movable groove 102, and then the clamping block 107 is separated from the adjustment hole 402, and the restriction on the adjustment rod 401 is released, and then the hand-held block is moved to adjust the overall length of the wrench body 1;
[0044] After the adjustment is completed, the moving block 105 can be loosened, so that the moving block 105 and the movable block 104 rebound under the elastic force of the movable spring 103, and then the clamping block 107 is pushed against the outer surface of the adjusting rod 401 through the connecting rod 106, and then the connecting block is slightly moved, so that the adjusting hole 402 on the adjusting rod 401 corresponds to the position of the clamping block 107, so that the clamping block 107 is inserted into the adjusting hole 402, and the position of the handle block and the adjusting rod 401 is fixed, thereby completing the overall length adjustment of the wrench body 1;
[0045] At the same time, during use, the adjustment rod 401 can be completely separated from the adjustment slot 101, so as to separate the connection block from the handheld block, so as to facilitate storage and carrying by maintenance personnel;
[0046] Then, during the movement of the clamping block 107 , the movement direction and distance of the clamping block 107 can be limited by the setting of the limiting rod 109 and the limiting groove 108 .
[0047] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
