Description

Technical Field

[0001] The present application belongs to the field of wrenches, and in particular to a wrench with a detachable handle. Background Art

[0002] A wrench is a commonly used installation and disassembly tool, a hand tool that uses the principle of leverage to twist bolts, screws, nuts and other threaded fasteners that hold the openings or holes of bolts or nuts.

[0003] The existing publication number is CN211841741 U, which discloses a wrench, including: a body, a clamping ring and a limiting mechanism. The clamping ring is rotatably connected to the first end of the body, and the limiting mechanism is arranged on the body and can move along the length direction of the body.

[0004] Although the limiting mechanism of the above-mentioned wrench can limit the retaining ring in the length direction of the body, thereby lengthening the lever arm of the wrench, making it easier to remove the nut, the wrench handle cannot be removed, resulting in inconvenience in storing the wrench when it is idle. Utility Model Content

[0005] The purpose of this application is to provide a wrench with a detachable handle in order to solve the above-mentioned technical problems. The wrench handle can be disassembled when the wrench is idle, so that the wrench can adapt to various storage spaces. At the same time, the wrench can be replaced with different wrench heads to work, thereby increasing the versatility of the wrench.

[0006] The present application provides a wrench with a detachable handle, comprising a wrench head, a wrench handle, an adjustment block, and also comprising:

[0007] A disassembly assembly, wherein the disassembly assembly is mounted on the wrench handle;

[0008] An adjustment component, wherein the adjustment component is mounted on the wrench handle;

[0009] Among them, the disassembly and assembly components include a fastening cavity, a fastening block, a control cavity, an electric lock, and a driving device. The fastening cavity is arranged on the adjusting block, the fastening block is installed in the fastening cavity, the control cavity is arranged on the wrench handle, the electric lock is installed in the control cavity, and the driving device is installed in the control cavity.

[0010] When the wrench is idle, the wrench handle can be disassembled, and the control driving device drives the electric lock to extend or retract to determine the combination or separation of the adjustment block and the wrench handle connected to the wrench head; when the driving device drives the electric lock to extend to cooperate with the fastening block in the control chamber, the wrench head and the wrench handle are connected and can work; when the wrench is not needed to work, the electric lock is driven to retract until the electric lock is completely retracted into the wrench handle to unlock; at this time, the wrench handle can be smoothly removed for storage, so that the wrench can adapt to various storage spaces. At the same time, the wrench can be replaced with different wrench heads to work, which increases the versatility of the wrench.

[0011] Furthermore, the electric lock comprises:

[0012] A locking member, wherein the locking member is mounted on the driving device;

[0013] a first external thread, wherein the first external thread is disposed on the locking member;

[0014] A first threaded hole is provided on the fastening block.

[0015] When the electric lock is required to cooperate with the fastening block in the fastening cavity to lock, the driving device drives the locking piece to rotate, and the first external thread on the locking piece cooperates with the first threaded hole on the fastening block. Under the cooperation of the thread, the locking piece can be moved in the first threaded hole of the fastening block in forward and reverse directions. When the locking piece is rotated into the first threaded hole, the locking work is completed, and when the locking piece is rotated out of the first threaded hole, the locking is cancelled. No manpower is required to lock or cancel the lock, thereby reducing the labor intensity of the user.

[0016] Furthermore, the driving device comprises:

[0017] A motor, wherein the motor is installed in the control chamber;

[0018] A battery, wherein the battery is installed in the control chamber;

[0019] A rotating shaft, the rotating shaft is mounted on the motor and is provided with a second external thread;

[0020] a second threaded hole, wherein the second threaded hole is disposed on the locking member;

[0021] A control switch, wherein the control switch is installed in the control chamber;

[0022] A protection component is installed on the wrench handle.

[0023] When the driving device is required to drive the electric lock to rotate and move, the motor is controlled to rotate forward and reverse through the control component. The motor is started by a battery. The battery is a rechargeable battery or a disposable battery. The start of the motor drives the rotating shaft to rotate. The second external thread of the rotating shaft cooperates with the second threaded hole on the locking piece. The second external thread of the rotating shaft rotates to transmit the locking piece provided with the second threaded hole. The locking piece can be moved forward or backward by reversing the rotating shaft, so that the locking of the wrench handle and the wrench head is more automated, more convenient and more efficient.

[0024] Furthermore, the disassembly assembly also includes:

[0025] A buckle slot, the buckle slot is arranged on the wrench handle;

[0026] A buckle cover, the buckle cover is installed on the buckle groove;

When the drive device needs to be controlled to be forward or reversed, it can be achieved by pressing the corresponding button block. The protective cover is slidably installed in the slide slot. The protective cover is used to protect the button block to prevent the button block from being accidentally touched and affecting the normal operation of the wrench. Protecting the button block increases the stability of the wrench's operation. The pull handle can make it easier for the user to slide the protective cover, reducing the user's labor intensity.

[0036] Furthermore, the adjustment component includes:

[0037] A first protruding block, wherein the first protruding block is mounted on the wrench head and a through hole is provided on the first protruding block;
