Description
Technical Field
[0001] The utility model relates to the technical field of wrenches, in particular to a magnetic elastic socket wrench. Background Art
[0002] A wrench is a commonly used installation and removal tool that uses the principle of leverage to turn bolts, screws, nuts, and other threaded fasteners. Wrenches are typically made of structural steel, either carbon or alloy, and are sturdy and durable. One or both ends of the wrench's handle are designed with openings or holes for clamping bolts or nuts. Users can apply external force to the handle and operate in the direction of thread rotation, easily tightening or loosening bolts, nuts, and other fasteners. A magnetic elastic socket wrench is a special type of socket wrench. Socket wrenches generally consist of multiple sockets with hexagonal or dodecagonal holes and are equipped with a variety of accessories such as handles and extension rods. They are particularly suitable for turning bolts or nuts in very narrow or deeply recessed areas. A magnetic elastic socket wrench may add a magnetic design to facilitate the absorption of bolts or nuts, as well as an elastic design, making it more convenient to use.
[0003] Since the holes reserved in the back panel are distributed at the four corners of the box, the space is very narrow, and there are various switches and wires. Most of the time, the staff's hands cannot reach the screws. When using a socket wrench or other tools to install the nuts, the nuts are easy to fall off and the threads are often not in place. Due to the length limitation of the socket wrench, most expansion bolts cannot be fully tightened, and the box often becomes loose due to the inadequate tightening of the nuts. For example, the patent with announcement number CN207415222U discloses a magnetic elastic socket wrench, which is provided with a socket wrench head, a first fixing plate, a second fixing plate, a magnet, and a spring. Among them, the interior of the socket wrench head is a cylindrical sleeve with a regular polygonal cross-section, the first fixing plate is a circular plate adapted to the inner diameter of the socket wrench head, and its diameter is smaller than the inner diameter of the socket wrench head; the second fixing plate is a circular plate with the same diameter as the inner diameter of the bottom of the socket wrench head, and is fixed to the inner side of the bottom of the sleeve of the socket wrench head; the spring is located in the hollow part of the socket wrench head, one end of which is fixed to the center position of the second fixing plate, and the other end is fixed to the first fixing plate and the magnet; when the spring is in a state of neither compression nor stretching, its length can make the outer end face of the component located in the socket wrench head flush with the end face of the socket wrench head, which can solve the problem of difficult installation and fixation of the low-voltage distribution box.
[0004] This patent uses components such as iron, springs, and isolation plates (i.e., the first fixing plate and the second fixing plate) to solve the problem of difficult installation and fixation of the low-voltage distribution box. However, when using the socket wrench, after the socket wrench is inserted into the bolt or nut, the magnet can adsorb the bolt or nut. However, since the bolts or nuts have different models and sizes, and the size of the hexagonal hole opened in the socket wrench is often fixed, after the bolt or nut enters the hexagonal hole of the socket wrench, a gap is likely to exist between the hexagonal hole and the bolt or nut. In addition, the bolt or nut cannot be well restricted or fixed, so that when the bolt or nut is tightened, the bolt or nut is likely to move or fall off, thereby failing to ensure a good tightening effect and inconveniently improving the applicability of the socket wrench. Therefore, in order to solve the above problems, a magnetic elastic socket wrench is proposed. Utility Model Content
[0005] The purpose of the utility model is to provide a magnetic elastic socket wrench to solve the problem mentioned in the above background technology that, due to the different models and sizes of bolts or nuts, the size of the hexagonal hole opened in the socket wrench is often fixed, so that after the bolt or nut enters the hexagonal hole of the socket wrench, a gap is likely to exist between the hexagonal hole and the bolt or nut. In addition, the bolt or nut cannot be well restricted or fixed, so that when the bolt or nut is tightened, the bolt or nut is likely to move or fall off, thereby failing to ensure a good tightening effect and making it difficult to improve the applicability of the socket wrench.
[0006] To achieve the above object, the present invention provides the following technical solution: a magnetic elastic socket wrench, comprising a housing, the housing comprising a cylinder, the top end of the cylinder being fixedly connected to a connecting rod, a gasket being provided on the inner side of the cylinder, the lower surface of the gasket being fixedly connected to a magnet;
[0007] A clamping mechanism is provided on the inner side of the cylinder, and the clamping mechanism includes an inclined surface block, which is movably connected to the inner side of the cylinder, a clamping block is fixedly connected to the surface of the inclined surface block, and a first spring is fixedly connected to the surface of the clamping block.
[0008] Preferably, the clamping mechanism further comprises a connecting sleeve, the connecting sleeve is sleeved on the surface of the cylinder, the surface of the cylinder is provided with threads, and the inner wall of the connecting sleeve is provided with an oblique groove.
[0009] Preferably, the inclined plane blocks are in six groups and are movably connected to the cylinder, and the connecting sleeve is movably connected to the cylinder via a thread.
[0010] Preferably, one end of the first spring is fixedly connected to the cylinder, and the other end of the first spring is fixedly connected to the clamping block.
[0011] Preferably, an auxiliary mechanism is provided on the inner side of the cylinder, and the auxiliary mechanism includes a fixed rod, which is fixedly connected to the inner wall of the cylinder, the inner wall of the fixed rod is fixedly connected to a second spring, and the surface of the second spring is fixedly connected to a movable rod.
[0012] Preferably, one end of the second spring is fixedly connected to the fixed rod, the other end of the second spring is fixedly connected to the movable rod, the movable rod moves inside the fixed rod, and the end of the movable rod away from the second spring is fixedly connected to the gasket.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. By rotating the connecting sleeve and cooperating with the setting of the thread, the connecting sleeve can drive the position of the inclined groove to change, and then the inclined groove can move downward to squeeze the inclined surface block. The clamping block can move under the action of the inclined surface block and can tighten the bolt or nut entering the cylinder, so as to achieve the effect of clamping the bolt or nut. Therefore, bolts or nuts of different sizes and types can be well fixed after entering the cylinder, which can prevent the bolt or nut from falling off from the cylinder, and can ensure the adsorption effect of the magnet on the bolt or nut, so that the socket wrench can stably twist the bolt or nut, which is conducive to improving the adaptability and flexibility of the socket wrench.
[0015] 2. By setting the second spring, the movable rod can move inside the fixed rod. After the magnet adsorbs the bolt or nut, the movable rod moves inside the fixed rod, and the gasket and the magnet drive the bolt or nut to move toward the inside of the cylinder. Then, the bolt or nut can better enter the cylinder, which can ensure the adsorption effect of the magnet on the bolt or nut, and also facilitate the clamping block to better clamp the bolt or nut, so that the bolt or nut is not easy to fall off.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1-5 , an embodiment provided by the utility model:
[0024] A magnetic elastic socket wrench includes a housing, the housing including a barrel 1, a connecting rod 11 fixedly connected to the top of the barrel 1, a gasket 12 provided on the inner side of the barrel 1, and a magnet 13 fixedly connected to the lower surface of the gasket 12. The magnet 13 can be used to adsorb bolts or nuts, and then the barrel 1 and the connecting rod 11 can be rotated to install and remove the bolts or nuts with the socket wrench, thereby making operation more convenient.
[0025] A clamping mechanism is provided on the inner side of the cylinder 1, and the clamping mechanism includes a ramp block 2, which is movably connected to the inner side of the cylinder 1, and a clamping block 21 is fixedly connected to the surface of the ramp block 2, and a first spring 22 is fixedly connected to the surface of the clamping block 2. The inclined groove 25 squeezes the ramp block 2, so that the clamping block 21 can clamp bolts or nuts of different sizes, thereby achieving the fixation of the bolts or nuts in the cylinder 1, making it difficult for the bolts or nuts to fall off, thereby facilitating the screwing of bolts or nuts of different sizes by a socket wrench, and improving the flexibility and applicability of the socket wrench.
[0026] Furthermore, the clamping mechanism also includes a connecting sleeve 23, which is sleeved on the surface of the cylinder 1. The surface of the cylinder 1 is provided with a thread 24, and the inner wall of the connecting sleeve 23 is provided with an inclined groove 25. Through the setting of the thread 24, the connecting sleeve 23 is rotated, and the connecting sleeve 23 can move on the surface of the cylinder 1. Then, the inclined groove 25 moves downward to squeeze the inclined block 2, so that the clamping block 21 can be moved under the action of the inclined block 2, which is convenient for clamping bolts or nuts of different sizes through the clamping block 21.
[0027] Furthermore, the inclined blocks 2 are movably connected to the cylinder 1 in six groups, and the connecting sleeve 23 is movably connected to the cylinder 1 through the thread 24. Through the setting of the clamping block 21, the bolts or nuts entering the cylinder 1 can be tightened, so that the bolts or nuts are more stable in the cylinder 1, which can ensure the effect of tightening the bolts or nuts.
[0028] Furthermore, one end of the first spring 22 is fixedly connected to the cylinder 1, and the other end of the first spring 22 is fixedly connected to the clamping block 21. Through the setting of the first spring 22, the clamping block 21 can be rebounded and reset, thereby facilitating the removal of the bolt or nut from the cylinder 1 or the placement of the bolt or nut into the cylinder 1.
[0029] Furthermore, an auxiliary mechanism is provided on the inner side of the cylinder 1, and the auxiliary mechanism includes a fixing rod 3, which is fixedly connected to the inner wall of the cylinder 1, and a second spring 31 is fixedly connected to the inner wall of the fixing rod 3, and a movable rod 32 is fixedly connected to the surface of the second spring 31. Through the elastic properties of the second spring 31, after the magnet 13 and the bolt or nut are adsorbed, force is applied to the cylinder 1 and the connecting rod 11, so that the bolt or nut can move toward the inside of the cylinder 1, and then the bolt or nut can better enter the cylinder 1, making it less likely for the bolt or nut to fall off, and the bolt or nut can be better screwed.
[0030] Furthermore, one end of the second spring 31 is fixedly connected to the fixed rod 3, and the other end of the second spring 31 is fixedly connected to the movable rod 32. The movable rod 32 moves on the inner side of the fixed rod 3, and the end of the movable rod 32 away from the second spring 31 is fixedly connected to the gasket 12. Through the setting of the second spring 31, the movable rod 32 can move on the inner side of the fixed rod 3, and then when the magnet 13 adsorbs the bolt or nut, the movable rod 32 moves toward the inner side of the fixed rod 3 to achieve tight contact between the gasket 12 and the bolt or nut, and then the bolt or nut can be better adsorbed with the magnet 13.
[0031] Working principle: When in use, the bolt or nut is inserted into the cylinder 1, the magnet 13 can adsorb the bolt or nut, and then the connecting sleeve 23 is rotated. The cooperation of the connecting sleeve 23 and the thread 24 enables the connecting sleeve 23 to move vertically on the surface of the cylinder 1, thereby realizing the lifting and lowering of the inclined groove 25. The connecting sleeve 23 drives the inclined groove 25 to move downward, and the inclined surface of the inclined groove 25 will squeeze the inclined surface block 2, and then the clamping block 21 moves in the cylinder 1 under the action of the inclined surface block 2. At this time, the first spring 22 is in a stretched state, which can realize the clamping block 21 clamping the bolt or nut, so that the bolt or nut is not easy to fall off; the connecting sleeve 23 is rotated to drive the inclined groove 25 to move upward, and the inclined groove 25 can cancel the squeezing of the inclined surface block 2, and then the clamping block 21 can be reset under the rebound action of the first spring 22;
[0032] When the magnet 13 and the bolt or nut are attracted, force is applied to the cylinder 1 and the connecting rod 11, so that the movable rod 32 moves inside the fixed rod 3 and the second spring 31 is deformed. Under the action of the movable rod 32, the gasket 12 can drive the magnet 13 to move upward on the inside of the cylinder 1, so that the bolt or nut can better enter the cylinder 1.
[0033] The above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
