Problems solved by technology

[0002] During the disassembly and assembly of the engine, due to the large number of internal parts and the small size of the box, the existing wrench is not only inconvenient to operate, but also easily interferes with other surrounding components, and the disassembly efficiency is low, and the force is applied due to local interference. Small, poor fastening, it is inconvenient to disassemble the long screws of the box
Therefore, it is necessary to improve the current wrench from the aspects of operating space and poor versatility of special tools, so as to solve the problems encountered in the actual operation and application process

Embodiment 1

[0029] Embodiment one: see Figure 1-Figure 5 , a quick-rotation wrench for vehicles according to the present invention, comprising a wrench body and a wrench head 4 arranged at the end of the wrench body, the wrench body includes a hand-pressed outer sleeve 1, and an inner sleeve that is matched and slidably sleeved in the hand-pressed outer sleeve 1 2 and the connector 3 fixedly arranged at the bottom of the inner sleeve 2, a guiding and rotating assembly is arranged between the hand-pressed outer sleeve 1 and the inner sleeve 2, and its wrench head 4 can be a socket wrench of different specifications on the market Head, socket wrench head matching activity card set on the connector 3.

[0030] Wherein, the guiding and rotating assembly includes a brake guide sleeve 5, a rotation guide sleeve 6 and a screw rod 7. The brake guide sleeve 5 is fixedly sleeved on the top of the inner sleeve 2 through threads, and the inner cavity of the brake guide sleeve 5 The bottom end is pr...

Embodiment 2

[0038] Embodiment two: see Figure 1-Figure 6, the structure of this embodiment is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that: when the pre-tightening force is too large to disassemble by pressing the outer sleeve by hand, press the outer sleeve by hand The tube and the inner casing are integrally fixed as one, and the disassembly and assembly are completed by using the wind gun, wherein the upper end cover 12 is provided with a pneumatic connection groove 16 connected with the wind gun transmission, and the hand pressure outer casing 1 and the inner casing 2 is provided with an integrated locking assembly, which includes at least one locking groove 17 provided on the outer wall of the inner casing 2 along the axial direction, and a locking groove 17 provided on the hand-pressed outer casing 1. Corresponding locking screw holes 18 and locking screw rods 19 matched in the locking screw holes, wherein the inner e...

Abstract

The invention relates to a dismounting tool. A quick-rotation wrench for a vehicle, comprising a wrench body and a wrench head arranged at the end of the wrench body. The connecting head at the bottom of the inner sleeve, a guide rotation assembly is arranged between the hand pressure outer sleeve and the inner sleeve; the axial linear motion of the hand pressure outer sleeve is converted into the rotation of the inner sleeve through the guide rotation assembly movement, which in turn drives the rotational action of the wrench head. In the present invention, through the cooperation of the rotating ratchet and the braking ratchet at the bottom of the rotating guide sleeve and the bottom of the braking guide sleeve, a unidirectional rotational force can be realized when pressing down the outer casing with the hand, and the screw can be tightened or loosened; When the brake ratchet is separated from the rotating ratchet quickly, the force transmission is interrupted, and the cooperation is smooth, so as to realize the one-way force transmission.

Description

technical field [0001] The invention relates to a disassembly and assembly tool, in particular to a quick-rotation wrench for vehicles. Background technique [0002] During the disassembly and assembly of the engine, due to the large number of internal parts and the small size of the box, the existing wrench is not only inconvenient to operate, but also easily interferes with other surrounding components, and the disassembly efficiency is low, and the force is applied due to local interference. Small, poor fastening, and it is inconvenient to disassemble and assemble the long screws of the box. Therefore, it is necessary to improve the current wrench from the aspects of operating space and poor versatility of special tools, so as to solve the problems encountered in the actual operation and application process. Contents of the invention [0003] Aiming at the problems and deficiencies mentioned above, the present invention provides a fast-rotating wrench for vehicles with...
