Description

A quick telescopic socket wrench

technical field

The utility model relates to a wrench, in particular to a rapidly retractable socket wrench.

Background technique

The socket wrench is composed of a socket head with a hexagonal hole or a twelve-point hole and a handle, which is especially suitable for disassembling and fastening bolts or nuts where the space is very narrow or deeply recessed; but the handle of the socket wrench is currently The length is fixed. When disassembling and tightening bolts or nuts of different depths in a narrow space, it is often necessary for the staff to carry a variety of socket wrenches of different lengths and specifications, which not only increases the cost of use, but also reduces the workload. efficiency, and it is easy to cause confusion and inconvenience in collection management, and when disassembling relatively strong bolts or nuts, due to the relatively short arm of force, it is more laborious to twist; although there are also telescopic socket wrenches on the market, such as now A rotatable and extendable adjustable wrench is disclosed in the prior art 201521118288.9, and a connecting rod extensible box wrench is disclosed in the prior art 201420397183.0, which are all adjusted through threads, resulting in slow adjustment speed and greatly reducing work efficiency.

Contents of the invention

The purpose of the utility model is to provide a rapidly retractable socket wrench which can adjust the length of the handle according to the working space or the size of the rotating torque in order to overcome the deficiencies of the prior art.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a rapidly retractable socket wrench, including a socket head, a support handle connected with the socket head, a slidable adjustment handle sleeved on the support handle, A locking mechanism that can fix the support handle and the adjustment handle on the adjustment handle; the support handle is a hollow structure, and the surface is provided with a chute placed along the axis of the support handle; the lock mechanism includes a The lock pin on the adjustment handle is placed along the radial direction of the adjustment handle and passes through the chute; The stopper and the locking toggle arranged on the eccentric locking sleeve can drive the eccentric locking sleeve to rotate to make the stopper move toward the center of the circle of the eccentric locking sleeve.

Preferably, the support handle is connected to the sleeve head through an angle adjustment mechanism; the angle adjustment mechanism includes two connecting pieces arranged on the head of the support handle and placed at intervals, arranged on the sleeve head and placed between the two connecting pieces Connection blocks between the sheets and connected by bolts.

Preferably, the locking trigger is arc-shaped, and its outer end is away from the surface of the adjusting handle.

Preferably, the locking mechanism is arranged at an end of the adjusting handle close to the sleeve head.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The rapidly retractable socket wrench described in the utility model can adjust the length of the handle according to the working space or the size of the rotating torque, effectively reducing the number of socket wrenches that workers need to carry, thereby greatly saving the use cost and improving work efficiency , and easy to carry, more labor-saving.

Description of drawings

Below in conjunction with accompanying drawing, technical scheme of the utility model is further described:

Among them: 1. Sleeve head; 2. Connecting block; 3. Bolt; 4. Eccentric locking sleeve; 5. Locking trigger; 6. Adjusting handle; 7. Connecting piece; 8. Locking pin; 9. Chute ; 10, support handle; 11, block.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Accompanying drawing 1-3 is the socket wrench that can be retracted rapidly described in the utility model, comprises socket head 1, the support handle 10 that is connected with socket head 1, is sleeved on the support handle 10 and can slide the adjustment handle 6 1. A locking mechanism that is arranged on the adjustment handle 6 to fix the support handle 10 and the adjustment handle 6 together; the support handle 10 is a hollow structure, and the surface is provided with a chute 9 placed along the axial direction of the support handle 10; The locking mechanism includes a locking pin 8 arranged on the adjusting handle 6 and placed along the radial direction of the adjusting handle 6 and passing through the chute 9, an eccentric locking sleeve arranged on the outside of the adjusting handle 6 and sleeved on the upper end of the locking pin 8 4. The block 11 arranged in the support handle 10 and connected to the lower end of the lock pin 8 is set on the eccentric locking sleeve 4 to drive the rotation of the eccentric locking sleeve 4 so that the block 11 moves toward the center of the eccentric locking sleeve 4 Locking toggle 5; when in use: the eccentric locking sleeve 4 can be driven to rotate by pulling the locking toggle 5, so that the stopper 11 approaches or moves away from the center of the eccentric locking sleeve 4 to realize locking and loosening.

Further, the support handle 10 is connected to the sleeve head 1 through an angle adjustment mechanism; the angle adjustment mechanism includes two connecting pieces 7 arranged on the head of the support handle 10 and placed at intervals, arranged on the sleeve head 1 and placed The connecting block 2 connected between the two connecting pieces 7 and connected by the bolt 3 can adjust the angle between the support handle 10 and the sleeve head 1 through the angle adjustment mechanism, so as to give the user an optimal operating angle.

Further, the locking toggle 5 is arc-shaped, and its outer end is far away from the surface of the adjustment handle 6, so that the locking toggle 5 can be pulled to adjust the length.

Further, the locking mechanism is arranged on the end of the adjusting handle 6 close to the sleeve head 1, which can maximize the extension range.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The rapidly retractable socket wrench described in the utility model can adjust the length of the handle according to the working space or the size of the rotating torque, effectively reducing the number of socket wrenches that workers need to carry, thereby greatly saving the use cost and improving work efficiency , and easy to carry, more labor-saving.

The above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. All technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the utility model.
