[0021] The utility model is described in detail below in conjunction with the accompanying drawings.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] A special bracket for extending a socket wrench, such as Figure 1-3 As shown, it comprises a lifting component 2, a base 1 is provided at the bottom of the lifting component 2, and a positioning seat 3 for supporting an extension rod 5 is provided at the top of the support rod.

[0024] Specifically, when the extension rod 5 is subjected to external force, deformation and internal force will occur. If there is no support, the extension rod 5 may bend, twist, stretch, etc., and strengthening the fixation and support of the extension rod 5 can reduce the deformation and internal force of the extension rod 5, and ensure the stability and safety of the extension rod 5. The overall height of the bracket can be adjusted by the lifting component 2, and then coordinated with the position of the extension rod 5. Specifically, by adjusting the height of the lifting component 2, the axis of the extension rod 5 is aligned with the axis of the screw to prevent the force from being offset during rotation. The bracket can be placed on the working plane through the base 1 to ensure the support stability of the bracket. The positioning seat 3 can be used to support the extension rod 5 and position the support rod to prevent the support rod from being offset or even detached during use, thereby improving the stability of the bracket.

[0025] As another specific implementation, the positioning seat 3 is detachably arranged on the lifting assembly 2. When the positioning seat 3 is removed, the present solution can be used as a temporary height-adjustable support bracket.

[0026] As another specific embodiment, the lifting assembly 2 includes an inner rod 21, and the inner rod 21 is provided with a sleeve 22, and the sleeve 22 can move along the axial direction of the inner rod 21. The inner rod 21 is also provided with a limiter 23. The inner and outer rods can provide reliable support and protection, and can also achieve limit in the lifting process and positioning in the subsequent process, thereby ensuring structural stability. In addition, the inner and outer rod method has a stable and simple structure, is easy to operate, and has low cost, which is conducive to promotion and use. The base 1 is threadedly connected to the lower end inner rod 21, which can be disassembled for easy storage. In addition, an anti-slip pad is installed at the bottom of the base 1.

[0027] As another specific embodiment, the inner rod 21 is a screw rod, and the sleeve 22 is provided with an internal thread, and the internal thread matches the screw rod. The threaded lifting mechanism has high transmission accuracy, is easy to adjust the lifting height, and can achieve stepless adjustment. It can also ensure stability and stability during the lifting process. In addition, the structure is simple and compact, the lifting process is safe and reliable, and the cost is low.

[0028] As another specific embodiment, the limiting member 23 is a locking nut. When torque is applied, the locking nut generates a certain pressure, and generates friction between the gasket and the screw rod by means of the elasticity of the spring, thereby achieving self-locking on the screw rod and limiting the sleeve 22.

[0029] As another specific implementation, the inner rod 21 is fixedly disposed on the base 1 , the limiting member 23 and the sleeve 22 are both disposed on the inner rod 21 , and the limiting member 23 is disposed below the sleeve 22 .

[0030] In contrast to the previous embodiment, as another specific embodiment, the sleeve 22 is fixedly disposed on the base 1 , the inner rod 21 is disposed in the sleeve 22 , and the limiter 23 is disposed above the sleeve 22 .

[0031] Of the two methods, the first method is preferred, in which the sleeve 22 is connected to the positioning seat 3. The sleeve 22 has a larger cross-section, thereby ensuring the stability of the connection.

[0032] As another specific embodiment, the positioning seat 3 is provided with an arc-shaped guide groove 31, and the central angle of the guide groove 31 is not greater than 180°. The arc-shaped guide groove 31 can match the extension rod 5 to position the axis of the extension rod 5. Specifically, the central angle of the guide groove 31 is not greater than 180°, which can prevent the extension rod 5 from being stuck in the guide groove 31.

[0033] A socket wrench extension assembly, such as Figure 1 As shown, it includes a socket wrench body 4 and an extension rod 5, one end of the extension rod 5 is connected to the socket wrench body 4, and a special bracket for extending the socket wrench as described above is provided below the end.

[0034] As another specific implementation, the diameter of the guide groove 31 of the positioning seat 3 is not less than the diameter of the extension rod 5. It is ensured that the extension rod 5 can be placed in the guide groove 31. Preferably, the diameter of the guide groove 31 is equal to the diameter of the extension rod 5, so that accurate positioning can be achieved.

[0035] The embodiment discloses a special bracket for extending a socket wrench, which is mainly composed of an upper sleeve 22 and a lower inner rod 21. The upper sleeve 22 has an internal thread, which cooperates with the external thread of the lower inner rod 21. The thread is a trapezoidal thread with a large load-bearing capacity. When using the socket wrench body 4 plus the extension rod 5 to disassemble and assemble the horizontal position bolt, according to the actual use requirements, the upper sleeve 33 is rotated to adjust the lifting assembly 2 to a suitable length, and then the locking nut is rotated upward to lock the upper sleeve 22, and the special bracket is placed just above the tail end of the extension rod 5, and the extension rod 5 is placed in the semicircular guide groove 31 at the upper end of the bracket.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The present invention is extended to any new features or any new combination disclosed in this specification, and any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.

[0037] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.
